Home Energy Efficiency in Fort Worth: Solutions by Calverley Service Experts Heating and Air Conditioning Did you know that, regardless of the actual heating and cooling system's energy efficiency rating, the average heating and AC system may only be 57% efficient at delivering conditioned air to the desired rooms in your home? This is usually because of significant deficiencies in the home’s duct system and/or insulation. Duct problems and insufficient insulation increases energy consumption and costs. As part of our Total Home Comfort approach, we conduct a thorough evaluation of your home's entire duct system (the “veins and arteries” of the home) to ensure that the air you are paying money to heat and cool is most efficiently getting to all of the rooms throughout your home. We’ll rate your system’s performance and actual efficiency level, including proper operation of duct work, registers and insulation. Many energy-wasting duct and insulation problems can be corrected with the right duct design, properly sealed ducts, and the recommended level of insulation for your home.
