COMMON HVAC PROBLEMS

Why is my AC running but not cooling?
The most common causes are a dirty air filter restricting airflow, a failed run capacitor preventing the compressor from starting, low refrigerant from a leak, or dirty condenser coils overheating the system. A $89 diagnostic tells you exactly which one — most are $150–$300 to fix.
How do I know if I need a repair or full replacement?
If your system is under 10 years old, repair almost always makes more sense. Over 15 years old, replacement often pays for itself within 3–5 years in energy savings. In the 10–15 year range, it depends on what's broken. We give you both options with honest numbers and let you decide.
Why does my house have hot and cold spots?
Uneven temperatures are usually caused by duct leaks, incorrectly sized equipment, blocked vents, or dirty coils. It's rarely a failing unit — more often it's an airflow or distribution issue we can address without replacing anything.
What's included in an HVAC tune-up?
Our tune-up covers coil cleaning, refrigerant check, electrical connection tightening, capacitor testing, filter check, thermostat calibration, drain line flush, and a full system performance test. Most breakdowns we see could have been caught at a tune-up.
