"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"Josh installed a new water heater, provided us with instructions on proper use and maintenance and has serviced it since. He is honest, thorough, and trustworthy. He also maintains my dad’s HVAC needs too. He has come out for emergency calls too. Suggest things to prevent future additional repair expenses. His prices are reasonable, especially for the personal, friendly customer service and service provided. I would highly recommend Northwoods HVAC."

"Estimator picked the wrong place to install it. Fortunately, the crew knew where it should go. It makes more sense for heat to rise and even I knew that. However I spent a lot of time making the appraiserâ s suggestion cleared for the job and it turned out to be a waste of my time."

"Matthew and his crew were extremely professional and efficient. The work was completed on the day scheduled and they cleaned up after themselves. Heat pump works great and they were able to direct me to an Effeciency Maine site where I received a substantial discount on the installation, equipment and cleaning plan!! Great company to do business with and will recommend them to family and friends. I will definitely not hesitate to use this company again if the need should arise!!"
