What Homeowners Say About Comfort Masters’ HVAC Services

“I first talked with Brian to get an opinion on the kind of service I needed. He was awesome and gave me great advice. Got a call from the scheduler in the office and she was very friendly, knowledgeable and helped get me the perfect time slot for my schedule. The technician Chris came by, was on time, polite and efficient. He did routine maintenance on my AC and furnace and checked for a minor problem with my AC. The price was very reasonable. I would highly recommend Comfort Masters!“​

“Our Carrier air conditioner wouldn’t turn on. Initially we thought the problem might also be with the thermostat. It was so easy dealing with Comfort Masters Ltd. They responded promptly to my service request and accommodated an early morning appointment to fit within my schedule. They sent regular text message reminders to keep me informed. The technician Sohrab arrived on time, removed his shoes without being asked, and was very professional. He immediately diagnosed the problem and provided helpful tips on how to maintain the A/C unit and furnace. He replaced the faulty part and had the air conditioner working in no time at all. I highly recommend Comfort Masters Ltd. to others and will not hesitate to contact them again in the future. Thank you, Sohrab and the Office Team!”
