Extending the Life of Your HVAC System – Things to Avoid

Extending the life of an HVAC system is doable. So, unfortunately, is shortening its expected service life. The combined average life expectancy of an air conditioner and furnace averages about 15 years. Typically, the furnace lasts longer than the A/C. However, that 15-year estimate is based on the assumption that both systems are professionally installed, receive regular maintenance and are operated according to manufacturer’s recommendations. If that doesn’t happen, all bets are off.

To increases the odds of extending the life of an HVAC system, avoid these mistakes:

  • Unqualified installation. Every new furnace or air conditioner should be properly sized to the BTU requirements of the home before installation. This means an accurate load calculation must be performed by a professional HVAC contractor. Over-sized and under-sized units not only under-perform in heating and cooling and cost more to operate, they tend to wear out much sooner.
  • Skipping annual check-ups. Your furnace or air conditioner manufacturer’s warranty probably requires yearly professional maintenance. That’s because it’s vital to maximize expected service life. Each unit should get seasonal preventive maintenance from a qualified HVAC technician at the outset of the heating and cooling seasons, respectively.
  • Ignoring important upkeep. As the homeowner, you can contribute to longer service life by changing the system air filter monthly—an easy DIY procedure that’s also inexpensive when you buy replacement filters in multi-packs. A dirty, clogged filter reduces system airflow. Low airflow not only raises operating costs, it also over-stresses vital system components like the air conditioner compressor and furnace heat exchanger. Early failure of these very expensive parts may mean early replacement of the entire unit.
  • Inefficient operation. Use of an outmoded manual thermostat often means the furnace or air conditioner is cycled on and off much more frequently. This adds to system wear and tear, shortens expected service life and consumes more energy. A digital programmable thermostat automates temperature changes with fewer on/off cycles to maintain a more comfortable indoor environment at lower cost.

"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."
