"responsive, and I only use him for HVAC."

"Highly capable, professional, thorough, and great at ongoing communication throughout the project. A total pleasure to work with. I had a very challenging HVAC issue that 67 degrees was able to solve after many had not been able to. I highly recommend hiring them!!!"

"Received a call back from Jeff within an hour. He was able to get to my job same day for the same price. Excellent job well done and great communication. Will use him in the future."

"Jake diagnosed a long running problem with my ac system (a poorly performing thermostat) and fixed it."

"Dan S. and Don N. both did an amazing job. They initially came late, but called to let me know that they schedule had changed, which is appreciated. They were going to replace both the furnace and the AC. They managed to get the furnace into working condition on the first day, which I needed because I had had no heat for the last couple of days. They finished complete installation in a few days. They left the area they worked in clean. They walked me through everything they were doing and why they had made certain choices. Very professional job. Will definitely use them again and recommend them."

"The team at TJ's HVAC is courteous, professional and very knowledgeable. You can count on the job being done right the first time, and their maintenance program is great. I have had numerous jobs accomplished by them including furnace replacement (upgrade), AC replacement (upgrade), air exchanger/purifier system installed, humidifier installed, water heater replacement, ventilation system/duct cleaning, and house water filter system installed. Their maintenance plan is perfect and maintains all my systems in tip top shape."

"Mike was above and beyond helpful! He even walked around the house and talked about my air conditioning and heating unit, which was great. He was knowledgeable and did great work."

"Buck and Wayne installed a mini split heating and cooling system in an attic bedroom/bath. The space was very tight and it took a lot of expertise and creativity on their part to hide all the piping. The outside unit mounted on the back of the house above a porch is a lot more visible than I thought it would be but they did everything they could to make it less intrusive. They arrived before 8 am and had to work outside in some bitter temperatures to install the outdoor unit. At the end of the day, Buck and Wayne took time to made sure that I knew how to operate the unit and that I could call if I had questions. I did a walk-through after they left and the rooms including the attic storage space were spotless. I would highly recommend them for any heating and cooling work you are considering."
