It’s not a luxury or option to have your central heating working effectively and efficiently. When your central heating system can’t keep up and keep your home warm, everybody suffers. By performing routine maintenance to your furnace, you should be able to avoid costly problems.
As you’re maintaining or trouble-shooting your central heating system, visit the U.S. Department of Energy for helpful information about one of the important components of your heating system – the ductwork. Although you can’t see every part of the ductwork system, it’s an integral part of the heating system, delivering warm air throughout your home.
Once you know the top five central heating problems, you’ll be in the perfect position to keep your house warm and comfortable.
1.Complete Loss of Heat
If you turn on your furnace and get absolutely no response from the heating system, the first thing to do is try to isolate the problem – figure out where the issue lies. If the heating system isn’t getting electrical power, you should probably call an electrician. Check the pilot light – is it igniting? If not, the issue probably lies in the gas supply and you should call the company that supplies your gas. Check the thermostat to make sure it’s set to “on” and that the temperature is set high enough to activate the furnace.
2.Partial Loss of Heat
If you notice that you are still getting heat, but the furnace doesn’t seem to be operating at peak efficiency, you may have a few different issues going on. It’s possible that your ductwork system has problems with leaks or blockages. If you have radiators, it’s also possible that your radiators need bleeding to release trapped air.
Because the ductwork system is so extensive throughout your home, there are many places where blockages can occur from rodents or insects. A ductwork blockage will generally require the service of an expert, who can diagnose and fix the issue. Ductwork leaks, resulting in heat escaping from the ducts and not expelling where you want it, also requires expert service to repair.
If you notice that the temperature of your home begins to have wild extremes, with high temperatures one minute and freezing temperatures soon after, the thermostat may be malfunctioning. This could cause the furnace to misread the actual temperature of your home and run when it shouldn’t or fail to run when it should. Call a professional to come out and recalibrate your thermostat. If your thermostat can’t be repaired, consider replacing it with a programmable thermostat that will help you reduce your heating bills.
For proper heating, the pilot light of your furnace must be lit continuously. If you check and you don’t see it lit, you will need to reignite it. If you see that the pilot light is on, check to assess its strength. The pilot light flame should be strong and blue – not yellow and weak. A weak pilot light could be a dangerous situation, resulting in high levels of carbon monoxide in your home, which could be fatal. Call a professional if you see indications of pilot light problems.
