All HighTech Heating and Airconditioning did an excellent job installing a furnace, a Central air unit and enhancing our electrical system. They came on time, were extemely professional, cleaned up thoroughly before they left and addressed all our concerns and answered all our questions. They had a competitive price (we had four quotes) and I would reccomend them to everyone who needs any of the above services. Shamsuddin (Bellevue)
