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.

Julianne M.

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!

Terry W.

Very responsive and thorough which is hard to find these days. The service was definitely worth the value.

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!

Jackie L.

Very nice to work with. I love the system a lot.

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.

Celene H.

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.

Todd P.

Patrick Boyle, my Technician, went above and beyond to complete my furnace tuneup to my Total Satisfaction. From the text to inform me that he was on his way, to a follow-up phone call to explain what work was preformed. This was my first time using Dual Temp, And they are now the ONLY HVAC company that I will ever use! Thanks Patrick…. And Dual Temp.

Peggy P.

Patrick was very knowledgeable and thorough. He did a great job servicing our heating and air conditioning units.

Bill D.

Best commercial HVAC company anywhere!

Stephanie R.

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.

Terry N.

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!

Marcia Z.

Patrick is amazing. So is the entire dual temp team. They really take their customer service to the level of extraordinary. I highly recommend dual temp for any and all HVAC needs. So happy they are doing residential now. Just amazing updated June 2025

Skylar S.

Awesome job very professional clean work

Ralph C.

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

Kevin B.

Always timely, polite, professional and informative. Makes making decisions easy. Great to work with outstanding service. I can highly recommend.

Steve M.

One of the best in the Lehigh Valley when it comes to HVAC!

Vicky D.

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 .

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!

Kadir M.

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

Penny R.

Great service! This company repaired my air conditioning unit this week . David is an awesome technician. He’s polite respectful and thorough. I’m incredibly happy with the companies service this week and David is a great representation of your company…. Thank you
