"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."

"Douglas was so very informative as to how to fix my heating and duct work issues I had to hire him do the job. Douglas was very professional and courteous. He charged for the job as he should, he showed up on time to do the job as promised and showed me what he was doing all the while answering any questions I had. He’s a stand up guy. He’s full of info regarding heating systems. He knows what he’s doing. Hire him to do your job. You’ll be so happy with him himself and his work you’ll want to refer him to your own family."

"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!!"
