Three tips for troubleshooting a thermostat

Setting a Dial Thermostat

Nothing can be more alarming than finding out that your thermostat doesn't seem to be responding and registering any changes. If you're in the middle of a heavy storm or a particularly dramatic cold spell, this is simply not a problem you want to be dealing with. But if you discover that your thermostat isn't working, and your favorite Gaithersburg HVAC service isn't picking up the phone, it may be a good idea to familiarize yourself with some of the most common problems that come up with these devices and how to diagnose them.

Here are some pretty frequent problems that we see with thermostats:

  • It's positioned poorly: If you feel like your thermostat works, but that it doesn't react quickly enough and seems to take a long time to respond to your living space being too cold, it may be in the wrong place. Ideally, it should be installed in a central location away from both sources of cold air, like a draft, and objects that create heat, such as electronics or a lamp.
  • Take the cover off your thermostat and make sure all the wires running into the unit are firmly attached and haven't come loose.
  • The dial is set to "cool" when it should be on "heat:" Sometimes thermostatsĀ have a switch that tell them to activate heating or air conditioning, depending on the season. If yours has such a setting, make sure it's on the right oneĀ and that it's not waiting for your home to heat up to a certain point so that it can activate the AC.

If you've tried fiddling with your thermostat and it just doesn't seem to be working, we recommend calling John C. Flood to have one of our Maryland heating repair specialists take a look. It may be a simple issue of wire connections, or it may be that the thermostat itself is old and in need of replacement or relocation to a new part of the house.
