Cooler summer temperatures are here, and it’s time to get the AC running. But you don’t have to pay a fortune for air conditioning. You can save big at home by switching to A/C units with energy-saving technology — and get comfortable in your own home without that cranking sound that drives you crazy! At Jack Kiefer Heating & Air, before we look to see what’s causing your air conditioning system to blow warm air up through the vents, we have to make sure nothing is causing a refrigerant leak. It could be as small as a loose piece of wire or power supply or something as large as a broken compressor or condenser. Our technicians will make sure before they dig any deeper into the problem. Moreover, Our licensed professionals can help you select the right size and type of air conditioner for your home. For more information, call our ac company in Neenah.
