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.

Wow, what a great experience! I had Dual Temp install a Tankless Hot Water Heater in my home. The entire experience and crew was tip top from 1st inquiry call to final install. Dual Temp was professional, experienced, respectful of my home and they worked really hard to make everything PERFECT.. They did such a great job, now i even gained closet space where the old hot water heater was!!! Thank you Dual Temp, I look forward to recommending you to my friends and family. Thanks again!!

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!

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.

Patrick Boyle was very knowledgeable and likeable. Great tech ❗

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.

Dual Temp is a dependable and customer focused organization. They quickly respond and the scheduling process is user friendly. Patrick has been to our home on multiple occasions and is thorough, explaining the work he’s doing, what he finds, and recommendations for repairs and/or upgrades.

A great company to partner with!

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!

google

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

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 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.

Patrick is polite and very informed. He shows concern and makes recommendations to address anything that could be problematic or preventative for future issues with our furnace.

google

Although we weren’t able to solve the problem during his visit, Patrick was very helpful in explaining the issue and course of action needed.

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.

google

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.
