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.
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.

Very professional and highly qualified. Worked on my commercial freezer and fixed a long time problem no one else has. Highly recommend and thanks!!!!
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
Joe was professional and personable. He shared all relevant information and added much to our understanding of what was available. A really good interaction.
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.
Fantastic service, very friendly, prompt.. overall they're just fantastic! Highly recommend!
Patrick did a nice job, very thorough, explained everything, streamlined a few items, pleasant and efficient.
Patrick was considerate and professional in installing our new hot water heater. It was a pleasure dealing with Patrick and everyone at Dual Temp.
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!
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!
Very pleasant atmosphere. Customer friendly. Has always been a pleasure dealing with any person there, from technicians all the way to the owner himself.
