What air conditioning repair involves
AC repair means checking the electrical side (capacitor, contactor, wiring), the mechanical side (compressor, fan motors), the refrigerant circuit (charge, leaks, metering device) and the air side (filter, coil, ductwork, drainage).
Central air diagnosis and repair — capacitors, contactors, fan motors, refrigerant leaks and drainage.
Common problems and warning signs
- Short cycling — starting and stopping every few minutes
- Outdoor fan spinning slowly or not at all
- Rising electric bills with no change in usage
- Hissing or bubbling near the lineset
- System worked fine last summer, nothing this summer
What the repair involves
For refrigerant problems we find and repair the leak, then weigh in the correct charge. Topping off a leaking system is a bill you get to pay again next year.
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 Sparta 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.
