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.

We are pleased to post the exceptional experience we received from DUAL TEMP today. From the initial contact with Kim , who professionally and promptly dispatched a skilled tech named Patrick. Between these two 5star team players , our HVAC issue was resolved in a timely manner and at a reasonable rate. We’re definitely going to be repeat customers and highly recommend them.

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.

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!

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.

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

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!

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.

S B.

David called to ask if he could arrive a little earlier than he was expected. He was coming to do my routine yearly service on my furnace. Once he was there he did an excellent job and I would definitely recommend Dual Temp!

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.

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.
