In the chill of the winter months, having a working furnace is imperative to the safety of your home and your family’s comfort.

While you can wait around for a professional to assess your system, it would be quicker if you fixed it yourself.

Here are some of the most common problems that people experience and tips on how to fix them.

Thermostat Problems

Some of the most common problems that you’ll experience will be with your thermostat. While it may seem like a no-brainer, many people tend to forget to change the setting on their thermostat to heat. For your furnace to work correctly, your thermostat needs to be set at five degrees above the room temperature. This will ensure that your furnace will continue to heat your home throughout the night.

If your thermostat doesn’t turn on, it may be due to the battery. It’s very common for thermostats to need their batteries replaced every few months. Most will take simple AA batteries or something similar. It’s best to have some extra batteries on hand so you can replace yours if they’ve run out of power. If you can’t find batteries on your thermostat, it likely runs straight to your home’s electrical system. In that case, it may be a problem with the breaker.

Furnace Isn’t Producing Heat.

When your furnace isn’t producing heat, it could be due to several different issues. Most of the time, they’re fairly easy issues to deal with and will only take a few moments to remedy. Once you’ve double-checked your thermostat to ensure that it’s on the heat setting, it’s time to move onto your home’s circuit breaker.

The breaker for your furnace may have blown. Check the breaker that is labeled for your furnace and see if it’s in the on position. If it’s not, then the breaker blew. Simply reset the breaker and see what happens. If the breaker doesn’t trip again, then you should be fine. However, if the breaker instantly trips, there’s a problem with your wiring. If you are still confused, then you can check

Not Producing An Adequate Level Of Heat

When it comes to producing heat, your furnace should be able to heat your home fairly quickly. Most homes will heat up in a couple of hours as long as there are no sub-zero temperatures outside. If it’s been a few hours and the heat isn’t getting any better, it could be due to a clogged filter.

When it comes to both your furnace and air conditioning system, they tend to utilize the same air filter. This filter needs to be regularly replaced every three months or so depending on various factors of your lifestyle. Take the filter out and check out its condition. If you can see through the filter, then it’s likely not a filter problem.

If you can’t see through the filter, then you have a clogged filter. Most homeowners use disposable filters. You’ll throw out the old one and replace it with a new one. If you have a washable filter, you’ll need to clean it thoroughly and then replace it. Either of these tasks should remove the debris from the filter and aid in the free flow of air in your system. Your home should heat up soon.

Furnace Isn’t Turning On.

Most furnaces are constructed with a safety switch on their door. This is to provide a measure of safety for the homeowner. How it works is, when the furnace door is opened, it pops the safety switch. This prevents the burner and fan from turning on when the door is open. Check to ensure the door is properly shut first. If this turns the furnace on, then you know that the safety switch wasn’t engaged.

Pilot Or Electric Light Issue

One of the oldest problems that HVAC professionals have been dealing with since the beginning of indoor heating is the pilot light. In gas furnaces, there is a pilot light that must be lit. It maintains a constant flame. When this light goes out, there is no heat for the furnace. In most newer systems, the traditional pilot light has been replaced with an electric igniter.

If you’ve switched from your air conditioning unit to your furnace and it isn’t working, you should turn it off. You’ll want to inspect the heating elements of the furnace. If the igniter looks cracked or damaged, it’ll need to be replaced. If it looks fully intact, then you’ll want to reset the igniter. Each furnace is going to have a different procedure for doing this. It’s best to follow the manual that comes with the furnace you have in your home.

Systems Noises

One of the scariest parts about owning an air conditioner and heating system is the unexpected noises. They crop up out of nowhere, and all you can think about is the money they’re going to cost you to fix. The truth is that some of these noises can be easily fixed when you know what to look for.

Rattling Noises – Likely, some of the panels on your furnace are simply loose. Go through and touch each panel to see if it moves and recreates the rattling noise. Tighten up the panel, and the noise should be eliminated.

Squealing Noises – This type of noise from your air conditioner or furnace indicates there is a problem with a belt. There is a belt in your system that connects the motor to the fan. If it’s slipping or wearing out, it’s going to need to be put back on or replaced accordingly.

Popping Noises – When you first turn on your furnace, you may hear some popping noises throughout your home. This is attributed to the expanding and contracting of the ductwork that runs throughout the walls in your home. It will go away after the ductwork reaches an adequate temperature.
