What air conditioning repair involves
We diagnose with gauges and temperature readings rather than adding refrigerant and hoping. If a system is low, it's low because it leaks — and the leak is the actual repair.
Central air diagnosis and repair — capacitors, contactors, fan motors, refrigerant leaks and drainage.
Common problems and warning signs
- Outdoor unit runs but the air inside isn't cold
- Air handler hums and the fan won't start
- Ice on the indoor coil or the refrigerant line
- Water around the air handler or a stained ceiling below it
- System trips the breaker
How we repair it
We finish by verifying superheat and subcooling, temperature split across the coil, and that condensate actually drains where it should.
Repair or replace?
If a repair keeps the system running reliably for several more seasons, that's what we recommend — even when a replacement would be the bigger ticket for us.
Questions from Sandyston homeowners
- How fast can you get out for no cooling?
- In hot stretches we run full days but voicemail gets a same-day callback and we work through calls in order.
- Should I replace the furnace with the AC?
- Only if the furnace is also near the end. If it's sound, we'll match a new coil and condenser to it.
