What to Know about Furnace Preventative Maintenance

Schedule Now

Fall is the season to think about furnace preventative maintenance. Don’t risk a major heating outage during the worst cold spell later this winter — that’s the time when a poorly maintained furnace is most likely to fail completely. Furnace preventative maintenance lowers operating costs due to improved energy efficiency, as well as delivering more effective heating performance. Because a gas-fired furnace involves a high-temperature open flame, flammable natural gas and dangerous exhaust byproducts like carbon monoxide, for safety reasons it’s best to leave most maintenance to a trained, qualified HVAC technician. Here’s what you can do and what to leave to the pros.

Change the Filter

Adequate system airflow is critical to all heating functions, and a clean air filter is what keeps airflow rates up to specifications. Start the heating season with a fresh filter and keep changing it every month as the winter goes on. It’s an easy DIY task; ask your HVAC contractor to show you how if you don’t know.

Clear the Area

Vacuum dust and dirt from around the furnace cabinet. Move any items that may have been placed there over the summer a safe distance away from the unit.

Schedule a Fall Maintenance Check-up

Here’s where the professionals take over. A regular annual maintenance evaluation should be scheduled with your HVAC contractor at the outset of the heating season, ideally at the time of seasonal furnace startup. This allows a qualified professional technician to conduct a standard list of furnace preventative maintenance procedures to ensure optimal performance and efficiency throughout the season. Most importantly, the annual procedure includes critical safety checks to test for proper combustion and the presence of dangerous carbon monoxide emissions, as well as inspect the venting system. It also gives the technician an opportunity to detect any issues that could develop into a major malfunction later in the winter when the system is under maximum load.

To schedule furnace preventative maintenance this fall, contact the heating professionals at Apollo Home Heating, Cooling, Electrical and Plumbing.

"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."
