Common AC Problems We Repair
We fix all air conditioning issues including no cooling, weak airflow, refrigerant leaks, frozen evaporator coils, compressor failure, capacitor problems, dirty condenser coils, thermostat issues, and electrical faults. Our trucks are stocked with common parts so most repairs are completed in one visit.
Refrigerant Leak Detection & Recharge
Low refrigerant is one of the most common causes of poor AC performance. Our EPA 608-certified technicians can locate and repair refrigerant leaks, then recharge your system to the correct level. Simply adding refrigerant without fixing the leak is a temporary fix — we address the root cause.
All Major Brands Serviced
We service all major air conditioning brands including Carrier, Lennox, Trane, Rheem, Goodman, Bryant, American Standard, York, Daikin, and more. Central air, ductless mini-splits, and heat pump systems are all within our expertise.
When Repair Is Not Enough
If your AC is over 12–15 years old, requires frequent repairs, or uses R-22 refrigerant (no longer manufactured), replacement may be the smarter investment. We will give you an honest assessment and let you decide — no pressure.
