Furnace Repair, Installation & Replacement in Clemmons
Our furnace services cover the full range of what Clemmons homeowners need. We diagnose and repair heating problems across gas and electric furnace systems, handle complete installations sized to your home’s actual heating load, and manage full system replacements when repairs no longer make financial sense. Light commercial customers in the area are welcome, too.
Every repair visit starts with a diagnostic inspection so we understand the root cause before recommending any work. Our technicians walk you through their findings in plain language, answer your questions, and give you a clear picture of your options. Transparent pricing means no surprises. For homeowners facing a system replacement, financing options are available to make the investment more manageable, and weekend service availability gives you scheduling flexibility.
The Home Care Club: Year-Round Furnace Protection
A furnace that’s serviced regularly can run more efficiently, last longer, and be less likely to fail mid-winter. Our Home Care Club maintenance plan gives Clemmons homeowners a straightforward path to that kind of reliability. A typical preventive visit includes inspecting the heat exchanger, checking the ignition system, testing safety controls, cleaning key components, and verifying airflow throughout the system.
Catching a small issue in October can cost far less than a replacement in February. The Home Care Club is built around that logic, with flexible scheduling and weekend availability to fit your calendar. If keeping your heating system in peak condition year after year matters to you, it’s worth a conversation.

"Our experience with All Phase was very professional and very pleasant."
The All-Phase staff was very pleasant to work with. They were very helpful in explaining what we needed and how it would benefit us. Brad was very knowledgeable, helpful, and kind. Jessica was very courteous and helpful in scheduling and answering any questions we had. Their prices were fair and the techs were experienced. Would recommend them to anyone.

"I'll certainly call upon them again whenever there's a problem in the future"
I had problem with my cooling system which was caused by the negligent work of the previous company that I had hired. Apparently, system malpractice is not rare nowadays. All-Phase sent over Evan to rescue us from our air conditioning meltdown. He was a young fellow, but sharp as a tack. He had an aire of professionalism and respectfulness which has become uncommon, as if he had stepped out of the 1950s. The reason I picked the company was because the website made it appear as if were operated by a good family. They looked trustworthy. I wasn't disappointed in my decision. My expectations were exceeded. There was basically a thicket that had grown up around the outside unit, so he had to fight his way through it, in order to get the job done. There was not one complaint. He did the job fast and well, while maintaining a positive attitude the whole time. Even the dog liked him, and "killer" doesn't like anybody. When everything was finally completed, I was pleasantly surprised by the charge. It doesn't seem proper to site numbers, but it was very reasonable, and considerably less than what I was accustomed to. I'll certainly call upon them again whenever there's a problem in the future.

"Overall, it’s a great company with great morals and values that shine through the respectful treating of their customers."
I had a great experience! Ask for Evan. He came out promptly, diagnosed my heat pump quickly and came back the next day to fix it. In the process, I learned a lot about how heat pumps work. He really took the time to explain things. Would highly recommend!

"Derick, Gina, and the rest of the All-Phase team are absolutely amazing!!!!"
Highly recommend this team for your heating and AC needs. I have been a customer for almost 5 years now and I am enrolled in a maintenance plan (every customer should enroll in this). Not only do they keep up with the routine check-in's, they are also quick to respond when something goes wrong. Love this team!

A Furnace Partner for Clemmons, Not Just a Service Call
Clemmons sits about 10 miles southwest of Winston-Salem in the heart of Forsyth County, where winter temperatures in the Piedmont Triad can dip into the 20s. A furnace that can’t keep up isn’t just uncomfortable. It’s a real problem for families trying to stay warm and safe. As North Carolina natives, we understand these regional conditions and the housing stock common to this area.
Our reputation across Forsyth County is built on long-term relationships, not one-time transactions. Hundreds of local families have trusted us with their heating systems, and we take that seriously. Brad and Gina’s presence on every job site isn’t a marketing point. It’s how we make sure every installation and repair meets the standard we’d expect in our own homes. New system installations come with a 10-year labor warranty because we stand behind the work long after we leave.
