After receiving 5 estimates from various air conditioning and heating companies, my last call was to Green Heating and Cooling. The response was immediate and an appointment was set up for the following day. Gerti was the main principal who I met with to review my needs for an air conditioning and heating system. He was extremely knowledgeable, courteous, patient and quite detail oriented. After a lengthy conversation, I decided to award the contract to his company because of his thoroughness and the fairness of his price. The job was completed in a timely fashion with an excellent team of workers who were careful, clean, efficient and complete. In fact, I was so satisfied that I awarded them a second contract for a major electrical job what had to be done at our home. The questions is "Do I recommend them?" The answer is highly.
