AC Repair FAQ

How much does it cost to repair a central air conditioner?

Prices for residential air conditioning repair vary widely depending on what exactly needs fixing. We can give you a better idea of the estimated cost if you call and describe the issue. Sometimes we can even help people troubleshoot the problem over the phone! Rest assured we always provide a firm price quote up front before getting to work – you’ll never get stuck with surprise costs.

Why is my AC running but not cooling the house?

There are many things that could cause this – some easy fixes you can try on your own, others you’ll need a technician for.

  1. It’s always a good idea to check the fan setting on your thermostat – it could be the fan is set to run constantly (instead of only when the cooling system is engaged).
  2. Making sure your HVAC filter and outside AC unit are clean is another good way to troubleshoot.
  3. Finally, it could be the circuit breaker in your outside unit. If it’s tripped it’ll keep blowing air without cooling. If the outside circuit breaker trips repeatedly you should get it checked out by a professional.

If none of those work, it could be a refrigerant leak, duct leak or a bad compressor – all of which require an HVAC technician to resolve.

Why does my air conditioning keep going on and off?

AC short cycling can be caused by a few different things. The first thing to check is your air filter. A dirty filter reduces airflow and leads to a whole world of possible problems (including a frozen evaporator coil, one of the causes of short cycling).

It could also be a problem related to the location of your thermostat. If the temperature controls are near a particularly hot or cool area (like in direct sunlight, or close to an air vent) it can lead to constant on/off cycling.

Low refrigerant can also lead to short cycling. Low refrigerant means low pressure, which can trigger a safety shutoff. When off, pressure comes back up, the AC restarts, and the cycle repeats.

And finally, if the cooling system is too large for the home it’s installed in, this can also cause it to turn on and off frequently because it cools so quickly.

Whatever the cause, an air conditioner that turns on and off frequently needs to be addressed. Otherwise it runs up energy bills, increases your odds of a breakdown and reduces the service life of your equipment.

How long should a residential air conditioner last?

It’ll depend on the brand and age of air conditioner, and how well it’s cared for (or not) over the years. As a ballpark number, a modern high-efficiency residential cooling system should last for 15-25 years with proper maintenance. Learn more about replacing air conditioning systems.
