How to Perform Simple Furnace Maintenance

Schedule Now

Like anything we use on a regular basis, furnaces benefit greatly from regular maintenance. While furnace maintenance requires the assistance of a professional, there are also things you can do to keep your furnace working at its best. If you’re wondering what can you do to keep your furnace running smoothly during the cold Midwestern winter, here are a few tips to get you started.

Air Filters

Take the time every month to check your HVAC system air filter. (An important safety guideline is to turn off your furnace and fuel supply before inspecting and removing components.) Cleaning or replacing filters can help to reduce stress on your system. Make sure to:

  • Check for excessive dirt or buildup
  • Clean permanent filters by following manufacturer instructions
  • Replace filters as soon as dust has begun accumulating.

Overall Inspection

While you might not be a professional, most homeowners can spot something that doesn’t look quite right. Regularly check simple things such as ducts, seals and joints, and make sure the screws are in place.


Two great ways to assure safety in your home is to have a carbon monoxide (CO) detector installed in your home. Also make sure to keep the area around your furnace clear of clutter and clean.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
