How Balanced Home Ventilation Keeps You Comfortable

Schedule Now

Balanced home ventilation means exhausting stale indoor air and inducting fresh outdoor air in equal volume, without impacting indoor temperatures. Usually, that won’t happen simply by opening windows. Standard exhaust fans can remove too much indoor air, depressurizing the house and drawing in unfiltered hot outdoor air in summer and cold air in winter. Balanced home ventilation utilizes a technology called a heat recovery ventilator (HRV) to ensure that incoming and outgoing ventilation are equalized and temperature-controlled.

Here’s how balanced ventilation keeps your indoor air quality comfortable and healthy in all seasons:

  • An HRV system incorporates dedicated small-diameter ductwork to supply and remove air from living spaces. Both sides of the system connect to a central controller that includes twin fans and a heat exchanger.
  • Exhaust ducts take stale air from areas such as the kitchen, bathrooms and utility rooms and channels it through the central controller before exhausting it to the exterior of the house. Meanwhile, the intake stream inducts an exactly equal volume of fresh outdoor through the controller and distributes to bedrooms, living rooms and other common areas of the house.
  • Inside the controller, the heat exchanger transfers heat from the warmer air stream to the cooler stream. In summer, heat energy is extracted from hot incoming outdoor air and added to the cooler exhaust stream as it leaves the house, reducing the cooling load on your air conditioner and lowering costs. In winter, the reverse occurs: heat produced by your furnace is removed from the exhaust stream and transferred to pre-warm incoming cold, fresh air from the outdoors. As much as 90 percent of the heat energy can be recovered to minimize furnace cycles and keep heating costs low.
  • A variant known as an energy recovery ventilator (ERV) transfers heat just like an HRV but also extracts water vapor from the more moist air stream, transferring it to the drier stream. This reduces infiltration of excess outdoor humidity in summer and makes the indoor environment less dry in winter.

"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."
