Mathew and his team were incredibly respectful and professional considering the limitations of Covid 19 and me having a pregnant wife in the house too. He worked around our difficult schedule at all times and on top of the full retro fit, he even worked with the weather to make sure we didn't go without AC during the hot days.
He pulled down all the 70 year old duct work(that was totally clogged with dust) and put up much neater, more efficient ductwork. The retro fit made my basement look modernized and much cleaner. And let's not forget that my gas bill dropped 40%. He added air returns where we needed them and moved around the heat runs. What a difference. And when the thermostat i bought didn't work properly, Mathew personally came the same day i called him and reprogramed the thermostat to make it work proper with my system. I can't say enough good things about revolution energy.
