Our technicians specialize in repairing and installing A/C systems if yours is no longer cooling your home. The HVAC professionals at Zimmerman can assist you in having the most functional and energy saving cooling unit for your home. Besides traditional air conditioners and a/c-gas furnace systems, common Pennsylvania cooling systems include:

  • Heat Pumps: Very common cooling systems for Central PA residents, heat pumps are energy-efficient and transfer heat from inside your home to the outside air.
  • Geothermal Heat Pumps: Environmentally friendly and more energy-efficient than a traditional A/C system, geothermal heat pumps use the earth’s natural heat to regulate the temperature of your home through pipes that connect your home to a heat pump to the earth. When it’s hot outside, the geothermal heat pump whisks heat out of your home and back into the ground.
  • Ductless Mini Split: Without using a traditional duct system, ductless mini splits offer a variety of cooling options and installation locations. You can choose to have a single indoor and outdoor unit cooling single rooms of your home, or have an intricate system that efficiently cools your entire house.

If your current system is working, but you’re hoping to add upgrades for added efficiency, ask one of our technicians about adjustments that can be made to your current system. Options include improved air filtration, air purifiers, duct modifications, duct cleanings, attic insulation or zone control, or installing a new programmable thermostat.
