Thanks to McMaster HVAC I now have the BEST DESIGNED and MOST PROFESSIONALLY INSTALLED AND TESTED Heating and Air Conditioning System possible. With a Very Fair Price. James Maloney (super nice person) explained that my too small existing asbestos (health hazard) ducts could be removed and that new, better sealed, insulated & designed ducts would improve air flow. He and their Amazingly Thorough Tech, Andrew calculated that I could actually get a much higher SEER and quieter AC condenser and a better furnace and then - after testing - qualify for HUGE electric and gas company rebates. And it would cost less than getting less costly components with no rebates. The install went smoothly and fast - great teamwork. Then Andrew spent 4 hours testing for safety and performance using their $16,000.00 worth of special test equipment. The HERS rater (state Energy Upgrade official) certified that the test results were all extremely positive. Carrier is a Highest Rated brand. I called McMaster due to their Positive Ratings. They are the only dealer in the area to receive Carrier’s Presidents Award (and for 5 years running). I will now have lower gas and electric bills. I couldn’t be more pleased.
