Whole-House Ventilation Is One Important Spoke of the HVAC Wheel

Schedule Now

Addressing ventilation issues is key to improving air quality, maintaining proper moisture levels and controlling heating and cooling costs in your home. Air sealing methods in many of today’s airtight homes can trap harmful contaminants such as formaldehyde, volatile organic compounds (VOCs) and radon indoors. Improper moisture levels can cause mold and mildew, as well as worsen allergies and breathing problems. Proper ventilation techniques however, can reduce the heating and cooling load on your HVAC system and lower energy bills.

Benefits of Whole-House Ventilation

Whole-house ventilation provides controlled, uniform air circulation throughout your home using fans and duct systems to remove stale air and bring fresh air. There are four types of whole-house systems:

  • Exhaust systems – These depressurize your home, are relatively inexpensive and simple to install, and work well in cold climates. Exhaust systems, however, may increase heating and cooling costs and cause backdrafting in combustion appliances.
  • Supply systems – Supply systems pressurize your home, are also inexpensive and simple to install, and allow better control than exhaust systems. They prevent carbon monoxide backdrafting and allow dehumidification of outdoor air, as well as filtering of pollen and dust. They may also increase HVAC costs and can cause moisture problems in cold climates.
  • Balanced systems – These don’t affect the pressure in your home, but they do introduce equal quantities of air into and out of it. Though they’re a little pricier, they are appropriate for any climate. They don’t control moisture and can also affect heating and cooling costs.
  • Energy recovery systems – A superior choice to ventilate your home, these systems also minimize energy loss. In the winter, ERVs transfer heat from warm exhausted air to fresh (cold) air being brought into your home, and vice versa in the summer. They cost more than other systems, but reduce heating and cooling costs, making them cost-effective and a great choice for climates with extreme summers or winters. An experienced contractor is necessary to properly install these systems.

"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."
