Whether it is small problem or a large one, anything that keeps your furnace from working properly needs to be addressed right away. And some issues that are found and repaired soon enough can save you a lot of money down the road. What are some common problems, you ask?

Dirty Air Filters. Air filters should be cleaned or replaced once a month. Be sure to follow the manufacturer’s guidelines. Dirty filters make the furnace work harder to circulate air because it hinders the air flow. Eventually, it might affect the limit switch that runs the fan.

Too Much Noise. A noisy furnace can have many causes. There may be a mechanical malfunction or clogged air flow. Turning off and on too often can be a defective thermostat. Rumbling and sputtering is not the sign of a healthy or effective furnace.

Not Enough Heat. Obviously, you should make sure the unit is large enough for your space. After that, the thermostat should be checked to make sure it is working properly. Settings for the thermostat and working batteries can also affect this function. When all else fails, you should check the power and the pilot light.

Improper Maintenance. Your furnace should be inspected by a professional at least once a year. They can fix small problems and recommend preventative measures to keep your furnace running at top performance.

A well-functioning furnace is vital to your home’s comfort. It also reduces your power bill. Keeping ahead of the problems and following these few guidelines will give you a furnace that will last for years.

    It has been a while since the heating system has started making a lot of noises, and it has gotten me worried. I decided to research about it because I need some kind of confirmation before I go out and call a heating repairman. You said here that loud noises from the heating system can indicate a lot of things such as mechanical malfunction or poor air flow and that it must be seen by a professional right away. Thanks for sharing this. I will do something right away.

    I’m grateful for your advice that we should have a heating repair if there’s not enough heat on it. Aside from that, we’re also hearing an unusual noise from our unit. With these two instances alone, I guess we need to look for a professional contractor who can check our system at the soonest possible time.
