Your furnace is one of the most important appliances in your home. It keeps you warm and comfortable all winter long. But, like any other appliance, it can sometimes have problems that may lead to discomfort or even safety hazards. In this article, we will discuss five of the most common furnace issues.
1. The Furnace Won’t Turn On
Your furnace may not turn on for a variety of reasons. The most common reason is that the thermostat isn’t working. Check the batteries and make sure it’s set to “heat.” If you have a programmable or smart thermostat, try resetting it by holding down the power button for about five seconds.
If this doesn’t work, check if the furnace switch is turned on. If it is, then you probably have a tripped breaker or blown a fuse.
2. The Furnace Runs but Doesn’t Get Hot
If your furnace runs but doesn’t get hot, it may be because the air filters are dirty. Change the filters to see if the problem goes away. If it doesn’t, there could be a blockage in the airflow. Ensure the vents are clear of obstructions and that all of the registers are open.
3. The Furnace Makes Strange Noises
If your furnace starts making strange noises, there’s a good chance something is wrong. If it’s a rattling noise, that could mean something is loose inside or outside the unit. A high-pitched squeal could mean the blower wheel is loose or unbalanced. A grinding noise could be a sign that something has broken and is rubbing against another part of the unit.
Plus, you must also check with common furnace smells and what they mean, and call an HVAC technician to come to take a look at your furnace as soon as possible.
4. The Furnace Doesn’t Heat Evenly
If some rooms are colder than others, or the heat seems to be coming and going, you might have a duct problem. Your ducts may not be properly insulated, or they could have leaks that let heated air escape into your walls or attic space. You can check this by looking for dust blowing out of cracks in the ducts or insulation.
If you do have a duct issue, an HVAC company in Atlanta can help you fix it.
5. The Furnace Keeps Going On and Off
If your furnace turns on and off repeatedly, there’s likely an issue with the thermostat. Try resetting it by holding down the power button for about five seconds. If that doesn’t work, the thermostat may need to be replaced or you may need to replace your furnace.
These were the six most common furnace issues. If you’re experiencing any of these issues, don’t hesitate to call an HVAC technician for help. They can diagnose and fix the issue quickly, so you can get back to being warm and comfortable in your home.
