Frequently Asked Questions
Why is my AC not cooling my home?
Common causes include low refrigerant, a dirty air filter, frozen evaporator coil, faulty capacitor, or a failing compressor. Our technician will identify the exact issue.
My AC is running but not cooling — what should I do?
Check your air filter first. If it's clean, the issue may be low refrigerant or a refrigerant leak. Turn the system off and call us to prevent further damage.
How much does AC repair typically cost?
Repair costs vary widely depending on the issue. Minor repairs like capacitor replacement may cost $150-300, while refrigerant recharge or compressor issues can be more. We provide upfront quotes.
Is it better to repair or replace my old AC?
If your AC is over 12-15 years old and needs a major repair, replacement often makes more financial sense. We'll give you an honest comparison of both options.
