I live in the northeastern region of the country, in an area that is known for the long and severe winter weather. School closings and driving bans are a frequent occurrence. We experience blizzard conditions with record temperatures and snowfall. Because of the cold weather, I spend a lot of time inside the house. The furnace carries a heavy workload and often runs for eight straight months. My gas furnace is a top-of-the-line model that achieves a 98% AFUE rating. Despite the exceptional efficiency rating, my heating bills are expensive. I’m always searching for new ways to trim costs. I’ve taken every possible measure to tighten up the house and prevent the heated air from escaping. I’ve caulked and weatherstripped to stop the cold outside air from coming in. While these efforts minimize stress on the furnace and reduce energy consumption, I’ve also eliminated essential ventilation. I noticed that my house started to feel and smell a bit stuffy. There was an excessive amount of dust floating in the air and settling on surfaces. Vacuuming and cleaning didn’t make much of an improvement. I finally contacted an HVAC professional and asked for a recommendation. He encouraged me to install a heat recovery ventilator. The ventilation system operates 24/7, bringing in fresh air and pulling out stale air. It provides all the benefits of opening a window but without the energy waste. The ventilator actually uses the stale outgoing air to preheat the incoming air. It has helped to not only improve comfort and indoor air quality but reduce heating costs as well.
