Is your home the wrong temperature?
Learn how to troubleshoot common thermostat problems before calling for HVAC repair in
Baltimore when your thermostat is not working. Sometimes, a heating or cooling problem has
nothing to do with the heavy equipment, and if your system is short-cycling or refusing to turn
on, check your wall thermostat first. If the digital screen goes completely blank, the most
common culprit is dead batteries, so swap them out; if it remains blank, you may have a tripped
circuit breaker or a blown fuse on the furnace control board. If you notice mismatched
temperatures where the room feels hotter or colder than the screen reading, the thermostat
might be dirty inside or installed in a poor location like direct sunlight or near a drafty door. If
your HVAC system doesn’t respond when you change the temperature, ensure the switch is fully
locked into the heat or cool setting rather than stuck in the middle. If fresh batteries and a quick
dusting don’t solve the problem, Five Star HVAC can recalibrate your existing thermostat or
upgrade you to a smart, Wi-Fi-enabled model.
