We offer same-day scheduling in most cases. A certified technician arrives at your door ready to diagnose the problem and determine exactly what it takes to fix it.

After our evaluation, you receive a clear, written estimate tailored to your home and budget. No hidden fees, no pressure — just honest numbers and honest answers before any work begins.

Once you give the green light, our licensed technicians get straight to it. We travel fully stocked, so most problems are resolved in a single visit without waiting on parts.

Before we leave, we verify your system is operating correctly and clean up the work area completely. Your home gets its comfort back — and stays spotless.

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.

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.

Great Job!! I was really impressed with the in-depth knowledge that tech had with my system. Clean and thorough!

Daniella A.

We moved into an old home with an old oil furnace that we knew was on its way out. Joe, David, and crew were great and replaced our old furnace with a new one. We had only one issue which was that the additional room that was added onto this house in 2010 didn’t include a way to bleed out the baseboards. They found a solution and fixed the issue. Dual temp is a great company with great people!

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

Antonio P.

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.

Dottie M.

Patrick was very helpful. He told us exactly was he was doing and what was going on with our system. I would recommend Dual Temp for your home services needs.

Jim G.

Patrick showed up on time and is a great guy! He did a awesome job and is very knowledgeable. He was very thorough and ensured that everything was properly cleaned and works like new. Thank you!

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.

Ashita D.

Very professional and quick service. I highly recommend it.

Steve M.

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

Wellington A.

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.
