Most people’s heating and cooling systems are the last thing that is on their mind until it does not work. So you come home from a hard day of work and it if cold in your house. What do you do??
1) Check your thermostat:
Many consumers have thermostats that have battery back up. If your thermostat is blank take the thermostat off the wall and change the batteries. If your thermostat does not have batteries and is blank you may have a break in the line from the circuit board to your thermostat. In the case where your thermostat is showing a screen, turn up the temperature on your thermostat and press the hold button. By chance if your unit does come on the programs in your thermostat may not be set right.
2) Check your filter:
Filters should be changed once a month. Your filter may be clogged which is causing the unit to go off on high limit. If your filter is clogged replace the filter. Turn the unit off and then back on. If your unit does not fire, call a heating contractor.
3) Check your breaker:
Certain areas may experience power surges and pop your breaker. Go to your electrical breaker and make sure your breaker for your furnace is in the proper position.
If you ever hear an unusual noise/smell coming from your unit or these steps doe not rectify your issues call a qualified Heating contractor. Within the past 10 years furnaces have become more complicated with electronics and diagnostics that are involved. It often makes it more difficult for homeowners to troubleshoot and repair their own unit. When in doubt, contact your heating and cooling company.
