Common Furnace Issues to Look Out For this Season

February 17, 2017

No one likes to be stuck without heat during the colder months, and why should you have to be?! Professional HVAC technicians are specially trained in heating and cooling system maintenance and are readily available to you no matter where you live. But did you know there are things you can do before calling an expert to troubleshoot certain issues on your own? Here are some common furnace issues to look out for:

wall thermostat causing issues with your temperature

Thermostat Error

Most thermostat issues can be solved without hiring a professional. If you still have the manual to your thermostat, it’ll come in handy when your furnace isn’t heating properly. If you don’t, you should be able to access it on the web by entering the brand and model number. Ensure that your thermostat’s HEAT setting is in the “on” position, and that any COOL setting is set to “off.” Replace thermostat batteries if the screen isn’t working properly. Compare the temperature setting to the actual room temperature. If there is a wiring issue with the thermostat or the problem cannot be fixed with these simple steps, it’s best to call a professional.

Dirty Filter

One of the most common causes of furnace problems is a dirty air filter. Your air filter should be in a labeled area of your furnace and relatively easy to find. Filters should be checked once a month and changed whenever they acquire buildup (usually once every 1-3 months). Dirty, clogged filters are caused by dust and dirt entering your furnace and can cause overheating of the heat exchanger, causing the system to shut off. Filters can be purchased at your local hardware or grocery store!

Electrical Trouble

Believe it or not, furnace issues can sometimes be solved by simply restarting the power to your unit. If your furnace stops working, first make sure the electrical breaker to the system hasn’t been tripped. Then, shut off and turn back on the switch to your furnace from the circuit breaker. Wait 15 minutes and check to see if the issue has been corrected. As always, if you are uncomfortable troubleshooting electrical issues, seek the help of a professional.

No Gas

For gas-powered furnace issues, always make sure that the gas valve is turned on. If for any reason the flow of gas has been turned off or restricted, the furnace can cease to perform properly. Ensure that the pilot light is lit. Sometimes the gas company shuts off gas to certain neighborhoods while they are performing maintenance or tests. If necessary, call your gas provider and ensure that there is no current gas service interruption.

If your furnace or heating system is having any of the problems above, or is giving you other signs it isn’t working properly, give the professionals at Cool Breeze a call today.
