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
- AC runs nonstop and never reaches the thermostat setting
- Weak airflow at the registers
- Loud buzzing at the outdoor unit
- Musty smell when the system starts
- Upstairs is hot while downstairs is cold
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?
When it is time, we'll size the replacement to the ductwork you have and tell you honestly whether the ducts need work too.
Questions from Fredon 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.
