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.
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.
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!
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.
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.
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!
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!
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 from Dual Temp was very knowledgable, asked clarifying questions to understand what we want and what we need to get us the best benefit and pricing proposals. Very Satisfied!
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
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! 👍
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.
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 D'Agostino was very thorough, professional and knowledgeable about my furnace and heat pump. He explained about the failed part, gave me the option to replace or wait. Great service call. I will have Dual Temp and hopefully, David, for future maintenance.
Great tech, good communication and people skll s along good technical trouble shooting and diagnostic skills
We will definitely use Dual Temp again. From Joe doing the estimate to Patrick installing new baseboard heat registers they were friendly, professional and we were very happy with the price. Patrick did a great job, so happy we chose them!
Fantastic service, very friendly, prompt.. overall they're just fantastic! Highly recommend!
Patrick was very knowledgeable and thorough. He did a great job servicing our heating and air conditioning units.
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.
