We have completed many HVAC system change-outs this summer. We have frequently seen large holes in the return ductwork. We have also seen poorly vented attics, which result in temperatures over 130° F and should only be reaching a max temperature of 110° F. These issues cause your HVAC system to overwork, which drives up energy costs. If your A/C seems to be struggling this summer give us a call at the Office: (864) 485-6509 or (828) 415-3334.
