Retrofitting Your Gas-Fired Furnace Can Make Dollar Sense

Schedule Now

Looking for some ways to save money this winter? Want to make your house more energy efficient? Retrofitting your gas-fired furnace can make it more energy efficient, saving you money and keeping you toasty warm on these cold winter nights.

Here are a few ways of retrofitting your gas-fired furnace that you might consider:

  • Vent dampers: Adding a vent or flue damper keeps heat from escaping up the chimney by closing the boiler’s vent when it isn’t firing. Larger boilers benefit more from this retrofit than smaller ones, and a vent damper may not be cost-effective if you have a newer, properly sized furnace model.
  • Intermittent-ignition devices: If you have an older furnace or boiler that has a continuous pilot light, it can be retrofitted with an intermittent-ignition device. This device will light the boiler only when necessary, reducing fuel consumption.
  • Modulating aquastats: The water in your boiler is typically kept at 180 degrees when heating needs are not as heavy, like in the spring and fall. A modulating aquastat senses the outdoor temperature and lowers the holding temperature in the boiler, improving overall efficiency.
  • Time-delay relay: When this device is installed in your heating system, the relay sends a signal to circulate hot water throughout the system without igniting the boiler. After a certain amount of time the boiler will turn on.

Any one (or all) of these retrofits can improve the efficiency of your heating system, resulting in lower monthly bills and increased home comfort. Retrofitting your gas-fired furnace should only be done by a licensed HVAC professional. If you have any additional home comfort questions or would like to schedule a time to get an estimate, please feel free contact one of our experts at Apollo Home Heating, Cooling 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."
