Like other fables, home energy myths tend to be accepted and passed along without ever being subjected to scientific proof. Relying on untested methods for energy savings often results in the opposite: increased energy use and higher operating costs. Science doesn’t yet know everything about how to make a home as energy efficient as possible. However, we can be certain about a number of things that don’t work. Here are four home energy myths that don’t stand up to a closer look:
Myth: Upgrading attic insulation only causes more heat loss through the walls and floor.
Fact: Heat energy inside a house isn’t like air pressure. Fixing heat loss in one spot doesn’t increase heat loss elsewhere. Heat passes through solid surfaces by conduction and radiation. Wherever it’s installed, proper insulation inhibits heat loss and doesn’t cause it to increase elsewhere.
Myth: Closing supply vents in some rooms saves energy.
Fact: Your furnace or air conditioner doesn’t “know” if vents are open or not. It just keeps on generating the same amount of heating or cooling and the same amount of energy is consumed whether or not all vents are open. Closing supply vents may actually cause the system to run longer “on” cycles and use more energy.
Myth: When you turn off an electronic device, it stops consuming electricity.
Fact: Many devices such as battery chargers, printers and home entertainment equipment actually go into “standby” mode when turned off and continue to use some electricity, although at a reduced amount. Plugging these devices into a switched outlet strip then turning off the strip is the only way to completely stop electrical consumption.
Myth: Replacing standard windows with high-efficiency windows pays for itself in energy savings.
Fact: Not for a very, very long time. The high cost of window replacement rarely pays for itself in a reasonable time frame. For a low investment and fast payback, caulking and weatherstripping to seal air leaks and upgrading attic insulation are a better bet.

"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."
