Your home’s furnace requires a lot of care and attention. Ignoring it could lead to unit break down and failure. If your furnace does deteriorate, this could leave you unable to heat your home or access hot water.

During cold spells, limited access to heat can be a threat to life. Due to climate change, global temperatures are becoming very unpredictable and winters are becoming considerably colder than they ever have been in previous years.

Maintaining and caring for your furnace is the best way to ensure your family never has to worry about being left without heat. Keep reading to find out about the most common furnace problems and their respective fixes.

Blocked Filters

It is very common for people’s furnace filters to get blocked. If a filter gets blocked, air cannot circulate through it. Blocked filters can cause major problems and unit deterioration. If your furnace’s filters are blocked, now’s the time to act.

Delaying repairs can lead to problems getting much worse. The ultimate fix, according to United Filter, is to replace them. It is possible to clean them out but eventually filters become tatty and unusable. If yours have, totally replace them.

You can typically do this yourself although it’s worth enlisting a professional’s help if you don’t know what to do.

Malfunctioning Thermostat

A malfunctioning thermostat can cause big problems, especially if it’s set higher than it needs to be. Thermostats that are malfunctioning can either make your house uncomfortably warm, bordering on extremely hot or fail to kick in when your house gets cold enough.

The easiest way to repair a malfunctioning thermostat is to hire a professional who’s experienced in thermostat repairs. Unfortunately, it is typically not possible for people to repair their own thermostats.

Blower Running

Sometimes, furnace blowers run even when they’re turned off. This can be caused by a number of different things. It’s worth noting that if you do not repair this, it could lead to your furnace’s motor breaking down.

Sometimes, all that’s needed to fix this is toggling the fan’s limit switch. You can also repair this by flicking your unit’s fan from AUTO to ON or OFF. If none of these fix it, however, you should consider enlisting an expert’s support. An expert will be able to give your unit the care it needs to ensure that it does not deteriorate any further.

Cracked Heat Exchanger

An expert will be able to repair your heat exchanger relatively quickly. Make sure that you find the most qualified repairman that you can. A repairman’s reviews will give you insight into what they are going to be like to work with. Always read reviews.
