How to find, select and work with an HVAC Contractor:

  • Ask for referrals. Find out if your HVAC contractor offers rebates through BGE’s Residential HVAC Rebate Program. Ask people you know for references about the contractor’s installation or service performance, and if the job was completed on time and within budget. You also can contact local trade organizations for members in your area.
  • Get written, itemized estimates. Do not expect or accept a quote over the phone. When comparing contractors’ estimates, be sure to compare cost, energy efficiency, and warranties. A lowest price may not be the best deal if the equipment being offered is not the most efficient—your energy costs could be higher.
  • Look for evidence of quality work, rather than focusing on lowest price.
  • Ask for a load calculation, which uses design information on your home to calculate equipment size. Do not use an HVAC contractor who wants to size your unit solely on the square footage of your home.
  • Get it in ink. Sign a written contract before work gets started. This protects you by specifying project costs, model numbers, job schedule and warranty information.
  • Ask for qualified ENERGY STAR equipment. These products meet strict guidelines set by the U.S. Environmental Protection Agency and offer significant long-term energy savings. Contractors should be able to show you calculations of savings.
  • Choose a participating HVAC contractor who will properly inspect your home’s duct system and provide any sealing, repairs or modifications needed.
  • Ask for verification from the contractor that the system will be installed according to manufacturer’s specifications.
