Can AC Repair Lower My Electricity Bill?
In the summer, your air conditioner can account for as much as 50% of your household electricity usage. Common issues like a refrigerant leak, a faulty compressor, or a failing fan motor cause your air conditioner to work harder to remove humidity and maintain a comfortable temperature, leading to significant energy waste. By scheduling the repair as soon as possible, you can minimize the impact on your next utility bill and boost your home’s comfort.
Should I Repair or Replace My Air Conditioning Unit?
Generally speaking, if your AC unit is under 10 years old, it’s rare that you will need to replace it rather than have it repaired. There are some instances in which a replacement is your best bet, though. Age is the top determiner, so if your unit has been running for 10 to 15 years, it’s likely time for an upgrade. Furthermore, if your unit needs major repairs, a replacement is definitely needed. The best way to determine the move you should make is by having an A+ Derr professional out to assess the situation!

AC Repair FAQs
When should I have my AC unit repaired?
If your AC unit is met with issues that are hindering its performance, you shouldn’t wait to schedule an AC repair with us to get things back up and running. Delaying repairs will lead to worsening issues and possible shutdowns.
Why is my energy bill so high?
Abnormally high energy bills can be due to your AC unit utilizing more energy than it should, likely due to a failing component or refrigerant leak. If this is the case for you, there is likely an issue with it that should be addressed and corrected ASAP.
Should I turn off my AC if there's an issue?
Continuing to run your air conditioner while awaiting repairs can lead to increased electricity bills, safety risks, and increased wear on your unit, potentially leading to a more costly fix. We recommend turning off your AC and calling for repair as soon as possible if you notice weak airflow, strange noises, or odors.
