Whether you’re looking for prompt AC repair or to upgrade from your flimsy window unit to a central air conditioner, our NATE-certified technicians are experts in all AC makes and models. We provide the following services:

  • AC installation – Want to install an air conditioner in your home? Does your current AC unit need to be replaced? Our HVAC technicians can help you choose the best make and model air conditioning unit for your home without emptying your wallet.
  • AC repair – A broken air conditioner is never good news, especially when you need cool relief on a hot, muggy summer day. Let our licensed cooling professionals diagnose and repair your home’s cooling system and restore comfort to your home.
  • AC maintenance – Regular maintenance can help extend the life span of your air conditioner and increase your cooling system’s efficiency.

Heat Pump & Cooling Zoning Systems

GAC Services also has expertise in alternatives for homes where traditional HVAC systems aren’t the right choice.

  • Heat pumps: A heat pump is a device that uses smaller amounts of energy to pull heat out of the air or ground to heat a building. They can also be used in reverse to cool a building by pulling hot air out of a building.
  • Cooling zoning systems: A zoning system is a great way to keep your Maryland home warm in the winter and cool in the summer while maximizing your heating and cooling system’s efficiency. If you notice inconsistent temperatures throughout your house, consider adding a zoning system to your home’s comfort system.
