In the section where I live, the temperature fluctuates between twenty below zero and ninety degrees. All of us deal with an annual snowfall of approximately numerous feet, vicious wind chill, tons of rain, high winds and excessive humidity. I depend on either the furnace or undefined for most of the year, and devote half my budget to temperature control. Because of this, I’ve taken proactive strategies to reduce the workload of the heating and cooling system. I do everything possible to eliminate energy waste. I’ve replaced all the windows in the lake lake house with Energy Star rated windows. I’ve improved the integrity of the insulation in the walls, ceilings and attic. I’ve added ceiling fans, caulked around the windows and installed weatherstripping on the exterior doors. I’ve updated to a programmable control equipment to help regulate temperature and trim energy use when my family is either out of the lake house or sleeping. While these energy saving measures have significantly improved comfort and trimmed running costs of the Heating, Ventilation as well as A/C system, the same stale air is trapped in the house. There is no source of fresh air to ventilate contaminants such as dust, pollen, dander and bacteria. The air began to aroma musty, and there were concerns with humidity. I finally contacted a local Heating, Ventilation as well as A/C dealer to get recommendations to improve indoor air conditions. He recommended a heat reusey ventilator, which brings in fresh outside air without adding to the workload of the furnace or undefined. It really uses the preheated stale air to warm up the incoming air in the Winter season. The ventilator also helps with humidity in the Summer. The lake house is cleaner, aromas fresher and feels more comfortable, and yet I’ve cut back on the cost of temperature control.
