Absolutely incredible experience. First HVAC company to ask me if my airflow is comfortable. They did a thorough review and adjusted the dampers to provide better air flow and comfort. They did a really nice job installing a new humidifier for me. And also they installed a Reme Halo Air Purification in my home. They were professional and clean. Highly recommend.

After using another company to try to figure out an issue with our mini splits over the course of several visits, we called Dual Temp - they sent 2 people out the same morning who identified the issue within an hour, explained how the whole system worked, and explained the needed repairs. We’re very happy to move forward with Dual Temp and appreciate the professionalism and expertise!

I recently called Dual Temp to fix a broken hose faucet outside my house. I couldn't be happier with the service! Patrick arrived promptly, fixed the issue in no time, and was incredibly polite. He made sure the work was done neatly and left everything spotless. I again have water outside my house! A great experience! I'll definitely use them again!

I can’t say enough good things about our experience with Dual Temp. After several issues with our AC over the last several months it was determined that it was time to start looking for a new system. I called on a Friday morning to request a quote. They were able to have someone come out the same day. Joe was great. He was very nice and answered my husband’s questions as well as address a concern we had with air flow to our bedroom due to a smashed piece of ductwork that’s been that way apparently since the house was built. I had an estimate in my email around 5 PM that same evening. We were provided with 3 options in the quote. Sort of a good, better, best option. We had a few additional questions which I emailed Joe about and he was very quick and responsive to my questions. After getting one other quote from another company we decided to go with Dual Temp. After only 2 weeks from the initial quote our new system was installed this week. Patrick and David were the technicians that came to install and they were just as amazing to work with. They were polite, knowledgeable and explained the system and new thermostat very well. I am not one to typically write reviews but I do read them while doing my research. I can only suggest that you give them a chance at addressing your needs. Thanks again for the great service. I look forward to the same great service in the future for routine maintenance as needed.
