Before you hire

In Maryland, look up the company with the State Board of HVACR Contractors, and for home improvement contracts the Maryland Home Improvement Commission. This directory does not verify licenses. Ask for the license number and look it up before you sign, and ask for a Manual J load calculation before anyone sizes a heat pump.
