I live in the northeast, and the weather is always a problem.
The winter season tends to last around seven straight months, and brings temperatures down to twenty below zero. The windchill makes it worse, and the furnace runs just about non stop. Because of the damp and chill of spring and fall, we typically need to continue to rely on the furnace. Although the summer season is brief, the temperatures up into the nineties and excessive humidity require central air conditioning. Because of the high cost of temperature control, energy efficiency is a priority. I don’t want to waste any of my conditioned air or allow the outside air to come in. I’ve gone to great lengths to tighten up the thermal envelope and trim utility costs. While I’ve managed to improve the comfort of the home and reduce strain on the HVAC system, I’ve also eliminated necessary ventilation. The same stale air gets trapped inside the house. The air filters of the furnace and air conditioner aren’t sufficient to manage the airborne contaminants. Dust, dander, pollen and musty smells quickly become a problem. When there’s issues with indoor air quality, there’s also concern over health risks. After consulting with an HVAC professional, I ended up investing in a heat recovery ventilator. The ventilator is better than opening the windows. It brings in a steady supply of fresh air but with no energy waste. It helps to keep a cleaner, healthier and more comfortable home and actually helps out the heating and cooling system. The ventilator uses the stale air to preheat the incoming air in the winter. During the summer, it works to get rid of humidity.
