We have been using Dual Temp for several years now and we are very satisfied with the service. Reactionary maintenance and/or emergency items are hard to manage from a remote site. Dual Temp does a GREAT JOB of taking care of our maintenance needs and they react in a timely manner.

Chris O.

Dual Temp Home Services delivered a great customer experience - easy scheduling, proactive communications, and reasonable pricing. Our technician Patrick Boyle was awesome - arrived on time, friendly, knowledgeable, helpful, and courteous! A true professional! Definitely recommend having Dual Temp and Patrick support your HVAC needs!

Joe came over to give me an estimate on a new boiler. He was very professional and knowledgeable. He explained my options and answered all the questions that I had I feel it was a very productive meeting and I walked away feeling comfortable.

Ashita D.

Patrick Was quick professional and very knowledgeable and efficient

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.

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.

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.

we were on vacation when our air conditioner went on the fritz with only our dog sitter at our house. We called Dual Temp and they got a guy out there the next morning to work on it. The technicians name was Patrick, who is definitely accredited, his profession, very professional and friendly, got our system up and running in no time answered all our questions Any potential problems that we have that need to be addressed. What a great experience. These guys put us at ease and took care of our problems so it didn’t affect our vacation. Thank you, Dual Temp and Joe

Kris F.

Technician responded quickly on a holiday and we scheduled for a repair the next day. He was commutative and friendly through out the repair process as well as a problem solver when faced with a change. Pricing was more than fair!

Kathy D.

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.

Bill D.

Best commercial HVAC company anywhere!

Santa B.

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!

Mike K.

Very pleasant atmosphere. Customer friendly. Has always been a pleasure dealing with any person there, from technicians all the way to the owner himself.
