AC Not Turning On in Peterborough, NH

AC not turning on in Peterborough, NH is a control problem more often than a mechanical one. The thermostat calls for cooling, nothing happens, and the house heats up. Our crew starts on the low voltage side because that is where the answer usually is.

The 24 volt control circuit runs from a transformer in the air handler or furnace to the thermostat and out to the condenser. A blown 3 amp fuse on the control board kills the whole thing. So does a float switch in the drain pan that tripped because the condensate line backed up. That safety switch is doing its job, and the real fix is clearing the drain line.

Other causes on our list: dead thermostat batteries, a loose wire at the thermostat base, a tripped breaker at the panel, a pulled disconnect at the outdoor unit and a failed transformer. On older systems we sometimes find a rodent has chewed the thermostat cable where it runs along the foundation.

We test each point with a meter and show you the reading. Call (866) 703-1217 when your AC not turning on leaves you guessing.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Not Turning On in Peterborough, NH.

Talk to our crew
Why is my central AC running but not cooling the house?
The usual causes are a clogged filter, a dirty outdoor condenser coil, low refrigerant from a leak, or a failed capacitor that has stopped the outdoor unit while the indoor blower keeps running. Our crew measures the temperature split across the indoor coil to narrow it down before we quote anything.
Why does my AC keep tripping the breaker?
Common causes are a compressor struggling to start because of a weak capacitor, a shorted fan motor, a compressor with a winding shorted to ground, or loose and overheated wiring. Resetting the breaker over and over can make it worse. Leave it off and call us.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
What should I do before the technician arrives?
Check that the thermostat is set to COOL and below room temperature, check the breaker and the outdoor disconnect, and look at the filter. If there is ice, turn cooling off and run the fan. If there is a burning smell, shut the breaker off and leave it off.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
