Why Does My Thermostat Click When It Comes On?

January 20, 2020

There’s a chill in the air, and you instinctively reach for your home thermostat to turn up the heat. The thermostat clicks ominously, and you know this can’t be good. The question is what makes it click, and how can this situation be remedied?

It Clicks Because the Setting Is Too Low

Your thermostat should be set to a temperature above the current air temperature of the room. You may need to turn it up a bit to jump-start, especially if the heat hasn’t been used for a while. Turn the temperature setting down once the heating action begins.

Your Thermostat Clicks Because the Gas Supply is Off

Do you have a gas furnace heating your home? The most obvious reason for clicking is that your gas supply is turned off. The gas supply needs to be in the “on” position, and it needs to be connected to an electrical power source. If you smell gas at any time, turn off the gas supply and contact an HVAC professional immediately.

A Dirty Filter Is a Filter That Needs Replacement

The gas filter may be dirty and restricting the flow of heat. Clogged filters lower the efficiency of your heating system and raise the cost of monthly bills. Having the filter cleaned or changed completely every month is an excellent way to prevent this scenario.

Those Clicks Indicate That the Pilot Needs Some Attention

Clicking is an indicator that the pilot ignitor needs cleaning. A clogged pilot ignitor isn’t going to send timely signals to the furnace unit to operate at the direction of the thermostat. If you are familiar with the working parts of your furnace, you can remove the front panel and examine whether this is the case.

Better to have a Professional take a Look

When you’re dealing with a furnace, there’s always the chance of a potentially dangerous situation. It’s safer and far more convenient to have a certified HVAC technician from Hunter's Air & Heat, Inc. in Boling-Iago, TX, to assess whatever is going on with your heating system.
