How a 15-Minute Monthly Ritual Can Save You Thousands
Speaking of those air filters, what if we told you there’s a simple 15-minute routine that could prevent thousands in repair costs?
It’s true. Mark your calendar for the first of every month. That’s your AC maintenance moment. Check and replace dirty filters, clear debris around outdoor units, and listen for unusual sounds.
Clean condenser coils annually to maintain efficiency. This ritual prevents the costly cascade of failures that technicians profit from.
Dirty filters force your system to work harder, leading to frozen coils, compressor damage, and eventually complete system failure. Regular maintenance can significantly reduce expensive AC repairs, ensuring your system runs smoothly.
We’ve seen $8,000 replacements that could’ve been prevented with this simple monthly habit.
Essential DIY Maintenance Tips for Boosting AC EfficiencyBeyond the Filter: Additional DIY Maintenance Tips That Boost Efficiency
While changing your air filter monthly works wonders for efficiency, it’s just the beginning of your money-saving AC maintenance journey.
Don’t stop there! Grab a garden hose and gently clean your outdoor condenser unit‘s fins, removing debris that blocks crucial airflow.
Inside, vacuum your supply registers and return vents to eliminate dust buildup.
We also recommend checking your condensate drain line quarterly—pour a cup of vinegar through it to prevent clogs that could cause water damage.
Finally, clear vegetation around your outdoor unit, maintaining at least two feet of space for optimal performance. Regular maintenance, including cleaning and inspections, can lead to significantly reduced operating costs and ensure your system runs at peak efficiency.
These simple DIY steps keep your system humming efficiently between professional visits.
