Countless homeowners have problems with a much cooler house than desired in the course of the winter season. If one keeps the filter clean, gives the heating system yearly or bi-annual tune ups and keeps the thermostat at a consistent temperature, the furnace or boiler is most likely not to blame. Heat loss by means of leakages, gaps, and insufficient insulation is a large concern among homeowner. Nearly 30 % of these leaks are air leaks. Air leaks are happening in air ducts and venting.

Duct tape is a wonderful choice for leaky air ducts. To read more about adequate insulation and other sources of heat loss around the household, check this website out!
