Outstanding service and top notch customer service. Patrick came over was super friendly and very professional. He explained all my issues and options to get my home running safely again. I will definitely call again to schedule a full upgrade. Thanks to Patrick and this company I now know how I was blind to the dangerous furnaces I been running in my home. Thanks for coming right away when all the other companies only gave excuses and appointments for a future day.

David called to ask if he could arrive a little earlier than he was expected. He was coming to do my routine yearly service on my furnace. Once he was there he did an excellent job and I would definitely recommend Dual Temp!

David S.

Service was excellent. The technician Patrick Boyle showed up on time, check over other contractors work to make sure it was right, install the new part continued to make sure everything was correct before adding the refrigerant. He also explained everything that he was doing to me and answer all my question in detail, and I had a lot of questions. Would recommend to anybody needing HVAC work.

I recently had two HVAC units installed in my home by Dual Temp Home Services, and I have to say, they exceeded my expectations in every way. I’m not easily pleased, but from start to finish, their team went above and beyond. The installers were professional, efficient, and took great care to keep my house clean. They were also mindful of my pets, which I truly appreciated!

Matt H.

I recently had a great experience with Dual Temp. From start to finish, their service was top-notch. Joe, the sales manager, was incredibly friendly and knowledgeable. He came out the same day to give us quotes on both a tankless and a regular water heater, taking the time to carefully explain the pros and cons of each option. Once we decided on the best option for our home, David came out the next day to handle the installation. He was punctual, very clean in his work, and incredibly thorough. It was clear he took pride in doing the job right. Overall, I couldn’t be happier with the service we received. If you’re looking for a company that’s responsive, professional, and cares about getting the details right, I highly recommend Dual Temp Co Inc.

Hi ,we Hired Dual Temp to install a new gas furnace and new water Heater, They did an excellent job! They are very professional and the price was very reasonable. I would definitely hire them again in the future.Thank you !! Sincerely Harry R.

Antonio P.

Patrick was very professional in his time at my house. Went over my system to troubleshoot the issues I was having with my ac unit. Gave me a great description of what happened and options to repair. He also found an issue with my propane water heater that was a potential safety concern and I was able to get that resolved. It was still under warranty from our plumber so with Patrick find he was able to solve the issue. It was lucky I made the call to Dual Temp for Service.

Kathryn R.

Patrick is polite and very informed. He shows concern and makes recommendations to address anything that could be problematic or preventative for future issues with our furnace.

Celene H.

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.

Peter L.

Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff
