Does your home have an attic fan? It could be costing you on your energy bills. Attics can reach temperatures between 110-130 F during hot summer days. This air is being pulled into your home while your AC is running causing your AC to work harder. We estimate an attic fan can increase your heating and cooling costs by 4-10%. Isolating your attic fan can save you money off your power bill and improve your indoor air quality. Give us a call at Blue Ridge Heating and Air to find out how to save money on your energy bills.
