What air conditioning repair involves
Most no-cooling calls come down to a handful of failures. We work through them in order of likelihood and cost, cheapest and most probable first.
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
We finish by verifying superheat and subcooling, temperature split across the coil, and that condensate actually drains where it should.
When replacement makes sense
R-22 systems, failed compressors and units past 15 years with repeated repairs are the cases where replacement is genuinely the better value. We'll show the math.
Questions from Hardyston homeowners
- Why does my AC freeze up?
- Almost always low airflow or low refrigerant. Shut it off, let it thaw, change the filter, then call us.
- Can you just add refrigerant?
- We can, but low refrigerant means a leak. We'd rather find it than sell you the same repair every summer.
