When to Repair Your Old AC Unit: Key Factors to Consider Before Investing

Knowing when to repair your old AC unit in Bucks County, Pennsylvania, comes down to a few key factors that are especially relevant to homeowners across Doylestown, Newtown, Langhorne, Bristol, and Perkasie. The region’s humid summers, where temperatures regularly climb into the upper 80s and 90s with oppressive humidity rolling in from the Delaware River Valley, put enormous strain on residential cooling systems throughout communities like New Hope, Quakertown, Yardley, and Warminster.

The unit’s age is the first critical consideration. If your AC system is over 10 years old and has been cooling a colonial, farmhouse, or split-level home in Bucks County through a decade of increasingly intense summer heat waves, it is likely operating far below its original efficiency rating. Older units in historic neighborhoods like Newtown Borough, the preserved districts of Doylestown Borough, or the established residential streets of Levittown were often installed during periods when energy standards were significantly lower, meaning replacement could dramatically reduce your monthly utility costs with PECO Energy.

Frequent breakdowns are another red flag that Bucks County homeowners cannot afford to ignore, particularly heading into peak cooling season between June and August when service calls from local HVAC companies serving Bensalem, Chalfont, Hatboro, and Richboro are at their highest volume. When your system is demanding repeated repairs, the cumulative cost quickly outpaces the investment in a modern, high-efficiency replacement unit.

Rising energy bills represent perhaps the most telling signal for Bucks County residents, where summer electricity costs already run high due to the region’s combination of older housing stock, large square footage in properties throughout Upper Makefield Township, Solebury Township, and Plumstead Township, and the prolonged cooling demands created by the area’s humid continental climate. If your cooling costs keep climbing season after season, replacement is almost always the smarter financial decision that pays for itself within a few years of lower monthly PECO bills and reduced repair expenses.

How Old Is Your AC Unit?

When it comes to repairing your old AC unit, age matters more than you might think — and if you’re a homeowner in Bucks County, Pennsylvania, that reality hits a little closer to home. From the historic colonial properties lining the streets of Newtown and Doylestown to the newer developments spreading across Warminster, Lansdale, and Chalfont, the age of your cooling system directly impacts your comfort and your wallet.

If your system is pushing 10 years or older, it’s time to take a serious look at whether repairs are still worth it.

Here’s why: as units age, their efficiency drops, and you’ll start noticing higher energy bills and more frequent breakdowns. That’s money walking right out your door — and in Bucks County, where summers along the Delaware River corridor bring heavy humidity alongside heat, an underperforming AC unit isn’t just an inconvenience. It’s a real problem.

Bucks County’s climate is no joke. The region experiences hot, muggy summers where heat index values regularly push into the upper 90s and above, especially in landlocked communities like Quakertown, Perkasie, and Sellersville. Older units already struggling with efficiency don’t stand a chance keeping up with that kind of seasonal demand, forcing them to run longer, work harder, and break down faster.

Units older than 20 years are well past their useful life. This is especially relevant across older Bucks County neighborhoods — think the historic districts of New Hope, Bristol Borough, and Yardley — where homes were built decades ago and original HVAC systems may still be limping along.

Older systems frequently run on R-22 Freon, a refrigerant that the EPA officially phased out on January 1, 2020. Finding R-22 in Bucks County today means hunting down limited stockpiles through local HVAC suppliers, and the costs are steep. What once cost a few dollars per pound now runs dramatically higher, making refrigerant-related repairs on old systems financially painful.

Bucks County homeowners also face a unique challenge that many other Pennsylvania counties don’t: a large percentage of the housing stock predates modern HVAC standards. Properties throughout historic townships like Solebury, New Britain, Buckingham, and Wrightstown were designed long before central air conditioning became standard.

Retrofitted systems in these homes often operate under additional strain, accelerating wear and shortening equipment life spans even further.

On the flip side, Bucks County homeowners have a distinct advantage — access to a strong network of local licensed HVAC contractors serving communities from Levittown and Bensalem in Lower Bucks to Doylestown and Plumstead in Central Bucks and up through Upper Bucks communities like Riegelsville and Springtown. Getting a professional age assessment and efficiency audit from a reputable local contractor gives you the clearest picture of where your system stands.

Knowing your unit’s age gives you the power to make a smarter financial decision — repair or replace — before costs spiral out of control.

For Bucks County residents navigating aging homes, rising utility costs through PECO Energy service areas, and summers that seem to get longer and hotter every year, that knowledge isn’t just useful. It’s essential.

Is Your AC Breaking Down Too Often?

How many times have you called your HVAC technician this past summer alone? If it’s been three or more times over the past decade, that’s a red flag worth taking seriously — especially for homeowners in Bucks County, Pennsylvania, where summers bring punishing humidity and heat that push cooling systems to their absolute limits. Frequent breakdowns rarely happen in isolation — they’re usually a sign of deeper, underlying issues wearing your system down.

Bucks County’s climate is no joke. From the river towns of New Hope and Lambertville-adjacent communities along the Delaware River to the sprawling suburban neighborhoods of Doylestown, Newtown, and Langhorne, residents here deal with intense July and August heat indexes that regularly climb above 95°F.

Older homes in historic areas like Doylestown Borough, Perkasie, and Bristol Township — many built decades before modern high-efficiency AC systems existed — place even greater strain on aging HVAC equipment that was never designed for today’s extreme seasonal swings.

Here’s where the math gets real: if your repair bills are creeping past 50% of what a new unit costs, you’re essentially paying for a replacement without actually getting one. For the average Bucks County homeowner — whether you’re in a colonial in Chalfont, a twin in Levittown, or a farmhouse conversion in Plumstead Township — that means throwing money away on a system already on borrowed time.

And when major components like the compressor or condenser coil start failing, those repairs get expensive fast, particularly when local demand for HVAC technicians peaks during Bucks County’s brutal midsummer stretches.

The county’s mix of older housing stock, mature tree cover in neighborhoods like Yardley and Buckingham, and the region’s characteristically humid continental climate means AC units here often work harder and wear out faster than in drier parts of the country.

High pollen counts, seasonal moisture from the Delaware River corridor, and fluctuating spring and fall temperatures create conditions that accelerate wear on refrigerant lines, coils, and electrical components alike.

Your A/C’s reliability tells a story. If it keeps breaking down through Bucks County summers — the same summers drawing crowds to Peddler’s Village, Lake Galena, and Tyler State Park — it’s likely telling you its useful life is nearly over.

What Does Your Repair History Say About Replacement?

Your repair history doesn’t lie — it’s essentially a financial report card on your AC unit’s remaining value. For homeowners across Bucks County, Pennsylvania, from the historic rowhouses of Newtown Borough to the sprawling colonial-style homes in Doylestown and the newer developments in Warminster and Horsham, that report card carries serious weight when summer temperatures climb into the upper 90s along the Delaware River corridor.

If you’ve called a technician three or more times in the past decade, that’s your system telling you something important. Given Bucks County’s humidity-heavy summers — where communities like New Hope, Langhorne, and Yardley regularly experience heat indexes that push well past 100°F — an unreliable AC unit isn’t just an inconvenience. It’s a genuine health and comfort risk.

We recommend applying the 50% rule: if your repair costs are approaching half the price of a new unit, replacement makes more financial sense. Think of it this way — every dollar you pour into an aging system is a dollar that could’ve funded a reliable upgrade, especially when local HVAC contractors serving Bucks County townships like Middletown, Bristol, and Northampton can equip your home with modern, energy-efficient systems better suited to the region’s demanding seasonal swings.

Frequent breakdowns rarely happen in isolation. They usually signal deeper mechanical problems lurking beneath the surface. In Bucks County, where older housing stock in places like Perkasie, Quakertown, and Buckingham Township often runs aging ductwork and outdated infrastructure, those underlying mechanical issues tend to compound faster.

Continuing to invest in a struggling unit means escalating costs and inconsistent comfort — two things nobody wants heading into another long, humid Bucks County summer.

Are Your Energy Bills Quietly Climbing?

Sometimes the clearest sign that your AC unit is struggling shows up somewhere you mightn’t immediately connect to it — your monthly energy bill. For homeowners across Bucks County, Pennsylvania, from the tree-lined neighborhoods of Doylestown and New Hope to the sprawling suburban developments of Warminster, Langhorne, and Levittown, this is one of the most common — and most overlooked — signals that an aging system is losing its edge.

Bucks County sits in a climate zone that demands serious work from HVAC systems. Summers bring stretching stretches of high humidity rolling in from the Delaware River corridor, and the dense tree canopy in areas like Perkasie, Quakertown, and New Britain, while beautiful, can trap moisture around homes and push AC units to work harder. That effort shows up directly in your PECO energy bills.

Watch for these warning signs specific to Bucks County homes:

• Consistent month-over-month increases on your PECO bill through the June–September peak cooling season
• Rising energy costs even during mild shoulder months like May or early October, when temperatures along the Delaware Valley are moderate
• Your unit running longer cycles to manage the region’s notorious summer humidity, not just the heat
• Older Colonial-style homes and split-level properties common in Doylestown Borough, Buckingham Township, and Chalfont often suffer from uneven airflow, causing units to overcompensate
• Historic homes near New Hope and Washington Crossing that were retrofitted with central air may show earlier efficiency decline due to aging ductwork
• A single spike during a heat wave at Tyler State Park-level temperatures isn’t alarming, but sustained elevation across multiple billing cycles is a red flag
• Several consecutive months of elevated bills warrant scheduling a professional quote with a licensed HVAC contractor serving Bucks County

Homeowners in newer developments like those in Warrington, Horsham adjacent communities, and Southampton often benefit from homes built with energy efficiency standards in mind. However, systems installed during the building boom of the late 1990s and early 2000s are now reaching the end of their efficient service life.

If your home was built during that era, your AC may be costing you more than you realize.

We recommend tracking your monthly PECO expenses closely alongside average temperature data from the Doylestown weather station or the National Weather Service Philadelphia forecast zone, which covers Bucks County directly. If the numbers keep climbing, your aging AC’s efficiency is likely declining — and a newer, energy-efficient unit rated for the Mid-Atlantic humidity profile could actually save Bucks County homeowners significant money over the long term, especially heading into increasingly warm Pennsylvania summers.

When Does AC Repair Cost More Than a New System?

Once those PECO Energy bills start climbing and won’t come back down — whether you’re in Doylestown, Newtown, Lansdale, or anywhere across Bucks County — the next question hits fast: is it smarter to keep repairing the old unit or put that money toward something new?

Here’s a solid rule of thumb: if repair costs exceed 50% of what a new system costs, replacement wins. Major AC repairs in the Bucks County area often run $1,000 to $3,000, and that adds up fast for homeowners already managing the high cost of living in one of Pennsylvania’s most sought-after counties.

Bucks County’s climate creates a particular challenge. Summers along the Delaware River corridor — from New Hope and Yardley down through Bristol and Levittown — bring intense humidity and heat that push older systems past their limits.

Historic homes in Doylestown Borough, New Hope, and Langhorne that were built decades ago often house aging HVAC equipment that was never designed for the kind of extended cooling seasons Bucks County now regularly sees.

If your unit has needed three or more repairs over the past decade, reliability is already gone. For homeowners in master-planned communities like Toll Brothers developments in Warminster, Chalfont, or Horsham — or in the older row homes of Levittown and Bristol — frequent breakdowns signal that a system is costing far more than it should.

Units older than 10 years also tend to demand increasingly costly fixes, and many homes across Upper Makefield, Middletown Township, and Lower Makefield still have systems installed during the housing booms of the 1990s and early 2000s that are well past their prime.

If your unit still runs on R-22 Freon, that refrigerant has been federally phased out and is now scarce nationwide, making repairs in the Bucks County market even pricier.

Local HVAC contractors serving communities like Warrington, Buckingham, and Richboro are seeing R-22 service calls skyrocket in cost precisely because sourcing that refrigerant has become so difficult.

Pennsylvania’s Act 129 energy efficiency standards and available rebate programs through PECO Energy also make replacement a smarter financial move for Bucks County residents willing to invest in a high-efficiency system.

ENERGY STAR-certified units can significantly reduce cooling costs during the county’s characteristically humid summers, and newer systems handle the temperature swings between Bucks County’s cold winters along the Route 202 corridor and its sweltering July and August heat far more efficiently than an aging unit ever could.

Sometimes the smarter investment for a Bucks County homeowner isn’t another patch — it’s a fresh start that actually fits the demands of where you live.

Frequently Asked Questions

What Is the $5000 Rule for AC?

The $5,000 Rule for AC: What Bucks County, Pennsylvania Homeowners Need to Know

The $5,000 Rule helps homeowners in Bucks County decide when to replace an aging air conditioning unit rather than continuing to pour money into repairs. The formula is straightforward: multiply your AC unit’s age (in years) by the estimated repair cost. If that number exceeds $5,000, replacing the unit is almost always the smarter financial decision.

For example, if your AC unit is 12 years old and a technician quotes you $450 for a repair, the calculation looks like this: 12 × $450 = $5,400. Since that figure surpasses the $5,000 threshold, investing in a new system makes more sense than spending money on a unit that is already past its prime.

Why This Rule Matters Specifically for Bucks County Residents

Bucks County homeowners face a distinct set of challenges that make the $5,000 Rule especially relevant. The region experiences hot, humid summers along the Delaware River corridor, running through communities like New Hope, Yardley, Bristol, and Langhorne, where temperatures regularly climb into the upper 90s with oppressive humidity levels. Neighborhoods in Doylestown, Warminster, Horsham, and Newtown place heavy seasonal demands on residential HVAC systems, causing older units to work harder and break down more frequently.

The county’s housing stock also plays a significant role. Bucks County is home to a large number of older colonial, farmhouse-style, and Victorian properties, particularly in historic boroughs like Doylestown, Quakertown, and Perkasie. Many of these homes were originally built without central air conditioning and had systems retrofitted later. Retrofitted units in older homes often run less efficiently, age faster, and require more frequent servicing than systems installed during original construction.

Seasonal temperature swings across Bucks County are also more dramatic than in many neighboring regions. Winters along the upper county near Riegelsville, Durham, and Nockamixon State Park can be bitterly cold, while summers in the lower county near Levittown, Middletown Township, and Bensalem bring sustained heat and humidity. This wide temperature range means HVAC systems cycle on and off repeatedly throughout the year, accelerating wear on compressors, capacitors, refrigerant lines, and coils.

Understanding When Your Bucks County AC Unit Has Reached Its Limit

Most standard central air conditioning units are designed to last between 10 and 15 years under normal operating conditions. In Bucks County, where systems run aggressively during prolonged summer heat waves and shoulder seasons, many units begin showing signs of significant wear closer to the 10-year mark. Common warning signs that your unit may be approaching replacement territory include:

• Frequent refrigerant leaks, which are especially common in older systems using R-22 refrigerant, a substance that has been phased out federally and is now expensive and difficult to source
• Compressor failures, which are among the costliest repairs and often signal the beginning of the end for an aging unit
• Inconsistent cooling across rooms, a common complaint in older Bucks County homes with multi-story layouts, finished basements, or additions that strain existing ductwork
• Rising energy bills despite normal usage patterns, indicating the system is losing efficiency and working harder to maintain comfortable indoor temperatures
• Repeated service calls within a single cooling season, a clear signal that the unit is deteriorating

How Local Climate and Infrastructure Affect AC Longevity in Bucks County

The Delaware Valley’s humid continental climate means that AC units in Bucks County deal with high moisture loads throughout the cooling season. Units must not only cool the air but also dehumidify it continuously, placing extra strain on the system’s components. Homes near bodies of water, including the Delaware River, Lake Nockamixon, Core Creek Park, and Silver Lake Nature Center in Bristol, may experience even higher ambient humidity levels, which shortens the effective lifespan of poorly maintained systems.

Additionally, Bucks County’s suburban and semi-rural character means many homes sit on larger lots with mature tree coverage. While shade trees common throughout communities like New Britain, Chalfont, and Buckingham Township can reduce cooling loads, they also drop debris onto outdoor condenser units, restricting airflow and causing mechanical issues over time if units are not properly maintained and cleared.

Applying the $5,000 Rule as Part of a Broader Replacement Decision

For Bucks County homeowners, the $5,000 Rule should be treated as a starting point rather than a definitive answer. Local HVAC contractors serving areas such as Warminster, Levittown, Doylestown, and Langhorne will typically factor in additional variables, including your home’s square footage, existing ductwork condition, insulation quality, and current energy costs. Pennsylvania’s energy utility rates and available rebate programs through PECO Energy can also influence the overall cost-benefit calculation when comparing repair versus replacement.

Upgrading to a high-efficiency ENERGY STAR-rated system often qualifies Bucks County homeowners for federal tax credits under current energy efficiency incentive programs, as well as potential rebates from PECO, making replacement a financially attractive option when the $5,000 threshold is met or exceeded. Modern systems with SEER2 ratings of 16 or higher deliver significantly better performance in the humid conditions common to southeastern Pennsylvania, translating directly into lower monthly utility costs and more consistent indoor comfort throughout the cooling season.

What Is the 20 Rule for Air Conditioning?

The 20 Rule for air conditioning is a straightforward guideline that helps homeowners in Bucks County, Pennsylvania, make smarter financial decisions about their HVAC systems. Simply put, if your AC repair costs exceed 20% of the unit’s original purchase price, replacing the unit entirely is the more cost-effective choice. For example, on a $4,000 central air conditioning unit — a common system found in the colonial-style homes and townhouses throughout Doylestown, Newtown, and Langhorne — that replacement threshold sits at $800. If a repair quote from a local Bucks County HVAC contractor comes in above that number, investing in a new system makes more financial sense than patching an aging unit.

Bucks County homeowners face particularly relevant challenges when applying the 20 Rule. The region’s humid continental climate brings brutally hot and sticky summers, with heat indexes regularly climbing well above 90°F along the Delaware River corridor in New Hope, Bristol, and Yardley. That kind of sustained heat stress accelerates wear on compressors, capacitors, and refrigerant lines, especially in older homes throughout historic neighborhoods like Perkasie, Quakertown, and Buckingham Township, where housing stock can date back several decades or more.

Relevant entities and factors Bucks County residents should consider when applying the 20 Rule include:

• Unit age: Most central AC systems in Bucks County homes last between 15 and 20 years. Units installed during large residential development booms in communities like Warminster, Horsham, and Lower Makefield during the 1990s and early 2000s are now approaching or exceeding that lifespan.
• Repair type: Common costly repairs that trigger the 20 Rule include compressor replacements, refrigerant recharges due to R-22 freon phase-outs, and evaporator coil failures — all frequently cited by HVAC technicians serving the Route 611 and Route 202 corridors.
• Energy efficiency ratings: Older units running on outdated SEER ratings waste significantly more energy than modern systems. With PECO Energy serving much of eastern Bucks County, upgrading to a high-efficiency unit can reduce monthly utility costs, partially offsetting the replacement investment.
• Home size and layout: Larger properties in Upper Makefield and Solebury Township, or multi-story homes in Doylestown Borough, often run their AC systems harder and longer, accelerating mechanical wear and making the 20 Rule threshold easier to reach within a shorter timeframe.
• Local contractor pricing: HVAC service costs in Bucks County reflect the area’s higher cost of living compared to surrounding regions. Labor rates from established local companies operating out of Chalfont, Langhorne, or Warminster can push repair bills toward the 20% threshold faster than homeowners might expect.
• Pennsylvania rebate programs: PECO and PPL Electric Utilities offer energy efficiency rebates for qualifying high-efficiency AC replacements, which can make crossing the 20 Rule threshold an opportunity rather than just an expense for Bucks County residents.
• Seasonal timing: Given the county’s hot summers and the heavy demand placed on HVAC contractors between June and August, applying the 20 Rule proactively in spring — before peak season pricing and scheduling delays hit — is especially practical for homeowners throughout the county’s townships and boroughs.

Understanding the 20 Rule in the context of Bucks County’s climate, housing stock, utility providers, and local service market gives residents a meaningful decision-making framework that goes well beyond a simple dollar figure.

Is It Worth Fixing an Old AC Unit?

When deciding whether to fix or replace an aging AC unit in Bucks County, Pennsylvania, the answer depends on several key factors specific to the region’s climate and homeowner needs. The general rule of thumb is straightforward: if your repair costs exceed 50% of the replacement cost, it’s time to invest in a new system.

Bucks County homeowners face a particularly demanding cooling season. From the historic streets of Doylestown and New Hope to the sprawling suburban developments of Newtown, Warminster, and Langhorne, summers bring intense humidity and heat that push older AC units to their limits. The Delaware River Valley’s geography creates a humid continental climate that causes AC systems to work harder than in drier regions, accelerating wear and tear on aging units.

Older units—especially those common in Bucks County’s historic homes in places like Peddler’s Village, Washington Crossing, and Bristol Borough—tend to run on outdated R-22 refrigerant, which is now heavily regulated and expensive to source. This alone can make repairs disproportionately costly for local homeowners.

Beyond repair costs, energy inefficiency is a serious concern. An aging unit running through a Bucks County summer means higher PECO Energy bills month after month. Modern high-efficiency systems can dramatically reduce those costs, often paying for themselves within several years through energy savings alone.

For homeowners in communities like Quakertown, Chalfont, and Buckingham Township, where larger lot homes and older construction present unique HVAC challenges, a new unit also offers better zoning capabilities and improved air quality control—critical during Bucks County’s pollen-heavy spring and muggy summer months.

Is AC Good for BP Patients?

For residents across Bucks County, Pennsylvania — from the historic streets of Doylestown and New Hope to the suburban neighborhoods of Levittown, Newtown, and Langhorne — air conditioning is more than a comfort. It’s a meaningful part of managing blood pressure health.

Bucks County’s humid continental climate brings intense summer heat and high humidity, particularly along the Delaware River corridor and in densely developed areas like Bensalem and Bristol Township. This heat exposure triggers dehydration and elevated heart rates, two conditions that directly spike blood pressure levels. For BP patients in the region, staying in a consistently cool indoor environment helps stabilize cardiovascular function and reduce strain on the heart.

The county’s older housing stock, including the mid-century Cape Cods of Levittown and the colonial-era homes near Perkasie and Quakertown, often lacks modern insulation and efficient airflow, making indoor temperatures harder to regulate without a properly functioning AC system. Local HVAC providers serving communities like Warminster, Horsham, and Chalfont understand these structural challenges and can recommend systems suited to older architecture.

Beyond temperature, air conditioning in Bucks County homes filters out regional allergens, including pollen from the county’s abundant farmland, parks like Tyler State Park, and tree-lined neighborhoods in Yardley and Buckingham Township. Allergen-related inflammation and respiratory stress are known contributors to blood pressure elevation.

For BP patients attending follow-ups at St. Mary Medical Center in Langhorne or Grand View Health in Sellersville, local physicians consistently emphasize controlling environmental stressors at home, with indoor climate management being a primary recommendation.

Deciding whether to repair or replace your AC doesn’t have to feel overwhelming, especially for homeowners across Bucks County, Pennsylvania, where the region’s humid subtropical climate brings sweltering summers that push HVAC systems to their limits. From the historic rowhouses of Doylestown and New Hope to the sprawling suburban developments of Newtown, Lansdale, and Warminster, every home in Bucks County depends heavily on a functioning air conditioning system during those long stretches of July and August heat when temperatures regularly climb into the upper 80s and 90s with oppressive humidity rolling in from the Delaware River Valley.

We’ve walked you through the biggest factors—age, breakdown frequency, repair costs, and rising energy bills—so you can make a confident, informed choice. For Bucks County residents, those factors carry added weight. Older homes in communities like Perkasie, Quakertown, and Bristol often house aging HVAC systems that were installed decades ago and struggle to keep up with modern cooling demands. The region’s older housing stock, much of it built in the post-war boom years or even earlier in colonial-era townships like Solebury and Buckingham, frequently presents homeowners with units that are well past their typical 15-to-20-year lifespan.

Trust what the numbers are telling you. With energy costs consistently climbing and PECO Energy serving as the primary electric utility for most of Bucks County, inefficient older AC units hit local homeowners especially hard in their monthly utility bills. A system operating at a SEER rating well below today’s minimum efficiency standards is essentially draining money every time it runs, and during a Bucks County summer, it runs constantly. Homeowners in densely populated areas like Levittown and Langhorne, where homes sit close together and retain heat, often find their outdated systems running nonstop without ever reaching the desired thermostat setting.

Sometimes sticking with repairs makes perfect sense, particularly when your unit is under 10 years old and the repair cost falls well within the industry-standard “Rule of 5,000” threshold. Local HVAC contractors operating throughout Bucks County—many of them certified professionals familiar with the specific demands of both the county’s older architectural styles and its newer planned communities in places like Richboro and Holland—can give you an honest assessment of whether a targeted repair will extend your system’s useful life through several more cooling seasons.

Sometimes a new system saves you more in the long run, and for many Bucks County homeowners, a high-efficiency replacement unit qualifies for federal tax credits under the Inflation Reduction Act as well as rebates offered through PECO’s energy efficiency programs, making the upfront investment more manageable. Either way, you’re now equipped to make the smartest decision for your home and budget, whether you’re cooling a centuries-old stone farmhouse in Upper Makefield Township or a newer construction home in the growing developments along Route 611 in Warrington.
