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.

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!

Jackie L.

Ashi S.

Fantastic service, very friendly, prompt.. overall they're just fantastic! Highly recommend!

Michael S.

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

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 .

The best Home Heating, A/C and Water Heater Services Team is Dual Temp Home Services in Lansdale, PA Patrick was on time and did a thorough oil heat system and water heater maintenance service as part of my contract. He was professional, friendly and knowledgable.

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.

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.

Mike S.

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! 👍

Tom H.

A great company to partner with!

Marilyn C.

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.

Matt H.

I recently had a great experience with Dual Temp. From start to finish, their service was top-notch. Joe, the sales manager, was incredibly friendly and knowledgeable. He came out the same day to give us quotes on both a tankless and a regular water heater, taking the time to carefully explain the pros and cons of each option. Once we decided on the best option for our home, David came out the next day to handle the installation. He was punctual, very clean in his work, and incredibly thorough. It was clear he took pride in doing the job right. Overall, I couldn’t be happier with the service we received. If you’re looking for a company that’s responsive, professional, and cares about getting the details right, I highly recommend Dual Temp Co Inc.

Alec R.

The technician was punctual, thorough, clean, and friendly. Our home is in good hands with Dual Temp.

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.

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.

Bill M.

Very professional and highly qualified. Worked on my commercial freezer and fixed a long time problem no one else has. Highly recommend and thanks!!!!

Mike K.

Very pleasant atmosphere. Customer friendly. Has always been a pleasure dealing with any person there, from technicians all the way to the owner himself.

Joshua M.

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.

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.

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!

Duane O.

we were on vacation when our air conditioner went on the fritz with only our dog sitter at our house. We called Dual Temp and they got a guy out there the next morning to work on it. The technicians name was Patrick, who is definitely accredited, his profession, very professional and friendly, got our system up and running in no time answered all our questions Any potential problems that we have that need to be addressed. What a great experience. These guys put us at ease and took care of our problems so it didn’t affect our vacation. Thank you, Dual Temp and Joe
