Living in Elgin, Illinois, the weather is always a consideration! My friend and I don’t buy tickets to activitying events or concerts between the months of December as well as April because of the potential for blizzard conditions as well as icy roads. My friend and I need a wardrobe that includes heavy boots, wool coat, gloves as well as hats as well as shorts as well as tank tops, however it’s helpful to drive a four-wheel-drive automobile as well as necessary to own snow shovels as well as ice scrapers, however over the winter, the temperature is constantly below cold as well as constantly dips below zero, the snow can accumulate in feet overnight as well as the wind chill can be dangerous, then during Spring as well as fall, my buddy and I expect thunderstorms, high winds as well as heavy rainfall. There can be power outages as well as flooding… While summers are correctly short, they are hot as well as especially humid. I usually switch from running the heating system to starting up the cooling system system with no split in-between. There is seldom an opportunity to open the windows as well as welcome in fresh air, but because of the expense of heating as well as cooling, keeping a tightly sealed thermal envelope is a priority. I’ve caulked, insulated as well as weatherstripped to prevent energy waste, and however, the lack of natural ventilation creates concerns with indoor air quality! Contaminants get trapped indoors, circulated throughout the household as well as can lead to health risks. The air starts to feel stale as well as stuffy. When I mentioned these concerns to an HVAC dealer in Elgin, she recommended the upgrade of a heat reclaimy ventilator. An HRV brings in a steady supply of fresh air to replace the stale air. By using the outgoing air to preheat the incoming air in the winter, it lessens demands on the heating system.
