6 Simple Steps To Try Before Calling For HVAC Service

hvac tips before calling for serviceYikes! Your furnace or air conditioner isn’t working, what do you do? Checking these simple items first might be able to save you the cost of a service repair call.

Before you call for repair:

  1. Is the thermostat set in the correct mode? Verify that it is set either to heat or cool, and that the system is turned on. Most systems have a built in delay, so wait a few minutes after making any adjustment to see if your system comes on.
  2. Verify your thermostat batteries are not dead. Many but not all thermostats have batteries to do a variety of tasks.  It is a good idea to change your thermostat batteries every six months when you change the batteries in your smoke detector. Often there is an indicator on the display (look for something like “batt”) when the batteries are weak.  If you are not sure how to access the batteries (or if your unit has them at all), have your technician show you at your next preventive maintenance appointment.
  3. Make sure your windows are all closed. When we are at the time of year where you are alternating between running your HVAC system and opening your windows, it is easy to miss one.
  4. Check your airflow. If a decrease in your HVAC system’s airflow is concerning you, make sure that something is not blocking your supply or return air registers.  This is also a good time to make sure that the filter is clean or replaced with a fresh one.
  5. Check the outdoor temperature. Most air conditioners are only able to cool the air about 20 degrees from what the outdoor air temperature is. On a very hot day if your air conditioner seems to be struggling to keep up, just be patient and try to avoid activities that can heat up the house.
  6. Check your fuse box. Sometimes resetting the breaker is all that is needed to get your HVAC system running again. Be careful with this one though, if it happens more than once a technician should be called to determine the reason.

If your furnace or air conditioner does not come on, it is time to call the professionals. Call P.K. Wadsworth Heating & Cooling and one of our trained technicians will get your HVAC system running again.
