We have only been working with Dual Temp for approximately two months, but we cannot say enough good things about them. Our commercial building has a unique HVAC system, to say the least, and we have already had several occasions on which we have had to make service requests. Dual Temp responds to calls and emails quickly and keeps the customer updated of progress. Nate and his great team of techs—specifically, Noah, Jeff, Bill and the other Noah—are all knowledgeable and very relatable when sharing information and options. It was a very lucky day for us when we connected with Bob, our Dual Tech salesperson, who is diligent about keeping in touch to ensure our needs are being met. Dual Temp now has our finicky HVAC equipment up and running, and we are most appreciative!

Excellent trouble shooting and great remedial proposals. Knowledgeable and efficient technician

Wow, what a great experience! I had Dual Temp install a Tankless Hot Water Heater in my home. The entire experience and crew was tip top from 1st inquiry call to final install. Dual Temp was professional, experienced, respectful of my home and they worked really hard to make everything PERFECT.. They did such a great job, now i even gained closet space where the old hot water heater was!!! Thank you Dual Temp, I look forward to recommending you to my friends and family. Thanks again!!

Joe was prompt, professional & helpful! His communication skills are excellent & I appreciate the organization of his work flow. Very glad we were referred to him!

We are pleased to post the exceptional experience we received from DUAL TEMP today. From the initial contact with Kim , who professionally and promptly dispatched a skilled tech named Patrick. Between these two 5star team players , our HVAC issue was resolved in a timely manner and at a reasonable rate. We’re definitely going to be repeat customers and highly recommend them.

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.

HIGHLY RECOMMEND!! On time, friendly, informative, and super efficient. Extremely pleased with Patrick and the job he did servicing our boiler, tankless water htr, & mini-split systems. Great job! 👍

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

Patrick Boyle was awesome, straightforward and right to the point. That we didn’t follow through with the plan we knew exactly where we stood with Patrick and Dual Temp . Thank you, Ralph

Needed a new heating/ac system installed. Received a few estimates and had a friend refer me to Dual Temp because she had a great experience. Joe came out promptly and provided us with 4 options. Very knowledgeable in helping with our unique situation. Installation was prompt and quick. The young men who came out were extremely professional and very considerate. Would highly recommend them!

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.

Great Job!! I was really impressed with the in-depth knowledge that tech had with my system. Clean and thorough!

Our furnace decided to give us a problem and stop working on one of the coldest days of the year!!! I frantically called/left messages with numerous HVAC companies who either couldn’t help us because we weren’t regular customers or couldn’t get to us for at least two days! Our technician David returned my call, got info he needed to see if he could help and got back to me immediately to say he had the part and could be here in 30 minutes. He was extremely knowledgeable, professional and polite. Our furnace was repaired quickly and kicking out heat again. Price was also much lower than others for emergency call. We are very pleased and highly recommend.

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!

The technician was very professional. I had annual service on my AC, furnace and water heater. The tech reviewed findings with me and discussed options. He gave honest feedback even when the answer was probably not worth it considering the expected life of my water heater. That showed they are a company you can trust. Not one that just looks to sell unnecessary modifications. Very pleased and will continue to use their services .
