"So happy I worked with Magna for my issue! They came within 45 minutes of me posting on Angie's List... that has to be some kind of record. They diagnosed the issue quickly, clearly communicated what was needed and what the cost would be, and I moved forward with it. My AC was back up and running within an hour. Highly recommend! I've saved Magna Tech's phone number in my contacts and they will be the first company I call every time I have an HVAC issue."

"I cannot recommend Polar Bear HVAC more highly. They offered the most affordable quote of the pros that Angi recommended and they are a family-owned business with super kind and knowledgable staff. Additionally, they were able to work with me on a great financing deal for my new HVAC and got the job done in a day and a half. Would definitely go with them again."

"McCrea replaced a 20 year old HVAC system with a new Trane 4-ton XL16i condenser, XV80 furnace and new coils. The salesman, Mark, was very responsive to my request for quote changes or additional items, including financing options. He was very knowledgeable and patient through the entire process as I worked with other companies for competing quotes. As a result of Mark’s recommendations and excellent pricing, I added on a new Aprilaire 1210 filter box (including replacing a portion of the return duct work/box) and an Aprilaire 600M whole house humidifier. I was able to schedule install four days after signing the contract. The installers, Charles and Christian, arrived on time and removed the old and installed the new in about 7 hours. They provided an overview of system operation and cleaned up so well, you couldn’t tell that a significant installation had occurred. I would recommend McCrea, especially Mark, Charles, and Christian to anyone...they were professional and did an excellent job. My home is so much more comfortable with a system that will be better on the summer and winter utility bills."
