Great tech, good communication and people skll s along good technical trouble shooting and diagnostic skills
Having some issues with our ac, and Nate arrived promptly, diagnosed the problem, and got the job done efficiently. I would recommend Dual Temp to anyone.
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.
Patrick is extremely knowledgeable and did an excellent job servicing my heating system. I would highly recommend him to anyone!
Very pleasant atmosphere. Customer friendly. Has always been a pleasure dealing with any person there, from technicians all the way to the owner himself.
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!!
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! 👍
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.
Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff
Dual Temp Home Services delivered a great customer experience - easy scheduling, proactive communications, and reasonable pricing.

Dual temp home services have been great to work with. They are always on time for service calls, and they take great pride in their work. Patrick is really committed to sharing specifics to make sure that I understand. Recommend them highly as a trusted company!
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!
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.
Fantastic service, very friendly, prompt.. overall they're just fantastic! Highly recommend!
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 have the joy of working with the Dual Temp home services team on a regular basis. From Patrick in service, to David and Shawn in install, to Joe and Kim in the office, I can tell you these guys are truly top notch in their trade and even better human beings. They genuinely care for their customers and demonstrate it every day.
Patrick was considerate and professional in installing our new hot water heater. It was a pleasure dealing with Patrick and everyone at Dual Temp.
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!
Patrick was able to fix our furnace issue, including locating the spare parts at an acceptable price level. I appreciate the professionalism and quality of service. Thank you
Patrick did a nice job, very thorough, explained everything, streamlined a few items, pleasant and efficient.
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!
