Our HVAC checklist may save you unnecessary service calls

When our customers have a heating or air conditioning system that doesn't seem to be working properly, we'll go through the following checklist with them on the telephone. This helps our technicians to determine what the problem might be. Sometimes, it even prevents an unnecessary visit, saving our customers money.

Problem:
My air conditioning unit doesn't seem to be cooling.
What to investigate:
  1. Check the thermostat. Is it set on cooling mode? If not, switch it to cooling mode and that should solve the problem.
  2. Check the thermostat. Is the desired temperature setting below the current room temperature? (If not, adjust the desired temperature setting lower; the unit should now come on.)
  3. Do you have a utility company cycling box? If so, the utility company may be cycling off your air conditioner during periods of peak demand. If this is the case, the air conditioning should resume cooling within 15-30 minutes.
Problem:
The fan for my heating or air conditioning unit isn't running.
What to investigate:
Check the circuit breakers for both the indoor and outdoor unit.
Problem:
My heating or air conditioning unit does not seem to be working properly.
What to investigate:
  1. Check to see if the indoor unit is on. You can tell by the air coming through the registers.
  2. Check to see if the outdoor unit (for heat pumps and central air conditioning) is running. You can usually hear it or see the internal heat pump fan rotating.
  3. Check to see if the air filter is clean. Remove a filter from the unit and visually inspect it. If it is covered with dust and dirt, change it.

If you've gone through this checklist and can't resolve the problem on your end, give us a call. We'll schedule a service appointment with you right away.
