When the weather is cold outside, your HVAC system will work a lot harder to heat your home. This extra use can cause some common problems that may cause your system to not work properly. It can be things like the system coming on too often, or other problems with relay switches that can be tripped when there is too much of an electrical load on the system. These are three of the common problems that you will want to check on your heating system.
1. Tripped Breakers And Electrical Safety Switches
The electrical service for your HVAC system has many different safety switches. This can be the main service, breakers and switches for furnaces and AC units. When there is an electrical surge on the system, these safety switches can be tripped to prevent damage to your system. This is one of the first things you should check when your heating is not working. Check the breaker box, switches for the furnace and even the outside breaker for the AC.
2. Constant Running Of The System Due To Faulty Thermostat
When the thermostat on your system is bad, it can cause your system to not work properly. It may not come on at all, or it may constantly come on even when you do not need your heating. To check it, turn the system off, and then turn the temperature up and see if the system comes on. If the system starts when it should not, or does not start when it should, you will want to replace the thermostat of your HVAC system.
3. Check To Make Sure The Furnace Igniter Is Working
The igniter for your furnace is what lights the gas when the furnace comes on. If it is worn or dirty, your furnace may not come on when you need your heating. You can check this by removing the access panel on the furnace and then looking to see if the furnace lights when the heating comes on. If the furnace does not come on, you will want to turn the system off and call a repair service. You should also be careful while inspecting a gas furnace, and if you do not feel comfortable, contact a professional HVAC technician.
These problems can cause your furnace to quit working when you need it most. If you checked these things, and your heating is still not working, contact a heating service to get the problem fixed and your heating back on.
Hi! I'm Adam Burkhard. As a young lad, I never paid much attention to the cleanliness of my environment. Once my first son was born, however, I started scouring the house top to bottom to create the cleanest environment possible. Unfortunately, during that time, I uncovered a serious mold problem in my home. The problem was so bad, it caused my newborn son to develop an allergic reaction. We instantly hired professionals to remove the mold and restore our home to new. Since I was interested in the process, I followed along with each step to learn more. I want to use this site to give people hope about the ability to remove mold without a trace. It's definitely possible to restore a home after mold takes hold behind the walls or under the flooring. I hope you learn lots about mold remediation services from my site.
