Emergency service

Ice on the refrigerant lines or coil? Shut the system off at the thermostat, leave the fan running to thaw it, and don't restart cooling until the ice is gone. Running a frozen system can damage the compressor — the most expensive part in the unit.

FAQ

Common questions

Why is my air conditioner blowing warm air?

The usual causes are a dirty filter choking airflow, a frozen evaporator coil, low refrigerant from a leak, a failed capacitor or contactor in the outdoor unit, or a thermostat set to fan-on rather than cool. We diagnose on-site and quote before any work starts.

How much does AC repair cost in Peterborough?

It depends on the unit and the part involved. We give you a firm quote after diagnosing the problem, before any work begins, so the invoice matches what you agreed to. Estimates are free.

How often should my air conditioner be serviced?

Once a year, ideally in spring before the first hot stretch. An annual tune-up keeps the coils clean, verifies refrigerant charge and airflow, and catches worn electrical components before they fail on the hottest weekend of the year.

Why is my AC freezing up or icing over?

Ice on the lines or coil almost always means restricted airflow or low refrigerant. Start by checking the filter and making sure supply vents are open. Shut the system off and let it thaw before running it again, then call us — running a frozen system can damage the compressor.

When should I replace my air conditioner instead of repairing it?

Central AC units typically last 12 to 15 years. If yours is in that range, needs repeated repairs, or uses a refrigerant that is now expensive and hard to source, replacement often costs less over a few seasons than repeated fixes. We will give you the honest math either way.

Do you install ductless mini-splits?

Yes. Mini-splits are a good fit for additions, converted garages, older homes without ductwork, and rooms that never quite keep up with the rest of the house. Call us and we will assess what makes sense for the space.

Do you offer emergency AC repair?

Yes. We run 24/7 emergency dispatch, and heat is a real health risk for seniors, infants, and anyone with a respiratory condition. Do not wait it out if the house is not cooling in a heat warning.

What AC brands do you service?

We service Keep-Rite, Continental, Goodman, Rheem, and most other major central air and heat pump brands, along with the matching indoor coils and air handlers.
