Combination Boiler Replacement and Hot Water Combi Boiler Installation Services

When your combination boiler replacement becomes necessary, Dual Temp Home Services delivers expert installation solutions that restore reliable hot water and heating to your home. Our certified technicians specialize in replacing aging or malfunctioning combi boilers with high-efficiency models from trusted manufacturers like Navien, Lochinvar, Bosch, Weil McLain, and NTI.

Common signs that indicate your combination boiler needs replacement include water heater not producing hot water, persistent leaking, strange noises during operation, inconsistent water temperature, poor heating efficiency, bad odors, pressure relief valve dripping, pilot light issues, and visible tank corrosion. These problems often signal that repair costs will exceed replacement benefits.

Our replacement process begins with a thorough assessment of your home's hot water and heating demands. Whether upgrading from an older Weil McLain unit or replacing a failing Bosch system, we ensure proper sizing and installation for optimal performance. Each new combination boiler installation includes comprehensive testing, system commissioning, and homeowner education on efficient operation.

With Dual Temp's precision installation techniques, your new combi boiler will provide years of dependable service, combining space-saving design with energy-efficient operation. We handle all aspects of the replacement process, from removing your old unit to connecting and testing your new system, ensuring seamless integration with your existing plumbing and heating infrastructure.

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.

David came out and did a great job and was done within an hour. didn’t try to sneak in any kind of fees or charge for extra time.

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!

Cynthia G.

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 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!

John F.

The technicians that came today were professional and explained the problem clearly. We are looking forward to implementing the new system.

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!

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

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.

Ann S.

This was our first experience with Dual TempPatrick serviced our Two air conditioner units, he was very thorough and explained everything that he was doing took lots of pictures to share the condition of our units with us. We will definitely be using Dual Temp for other services

Monica H.

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!

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.
