How We Work

Getting Your Home Back to Comfortable Is Easy

Connect with our friendly team by phone or through our quick online form. Share a few details about the issue you're experiencing so we can dispatch the right technician with the right equipment.

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.

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.

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.

I recently called Dual Temp to fix a broken hose faucet outside my house. I couldn't be happier with the service! Patrick arrived promptly, fixed the issue in no time, and was incredibly polite. He made sure the work was done neatly and left everything spotless. I again have water outside my house! A great experience! I'll definitely use them again!

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.

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.
