Fast, honest heating and cooling help for Lewisville homes, with repairs, maintenance, and same-day system replacements available.
— Our Top Services
In Lewisville, a dependable HVAC system is not a luxury. It is part of daily comfort. Between long North Texas summers, sudden temperature swings, and days with high humidity, your air conditioner and heating system need to work hard almost year-round. At NTM Services, Inc., we help Lewisville homeowners keep their homes comfortable with honest HVAC service, clear communication, and quality workmanship.
We proudly serve families across Lewisville and nearby DFW communities. Whether you are near Old Town Lewisville, Castle Hills, Lake Lewisville, Vista Ridge, or Valley Ridge, we understand the kind of wear local weather puts on home comfort systems. Our job is simple: fix what can be fixed, replace what truly needs replacing, and make the process easy from start to finish.
Every home has different needs. Some homeowners call us for a fast AC repair during a summer breakdown. Others need a full HVAC replacement because an older unit cannot keep up, runs up utility bills, or needs frequent repairs. We service all major brands and we are a preferred Trane dealer, so we can recommend a system that fits your home, comfort goals, and budget.
As a family-owned company, we believe customers deserve straight answers. We do not push services you do not need. We explain your options clearly so you can make the right decision for your home.
If your system needs to be replaced, we make the process as smooth as possible. Replacement estimates are free. After we inspect the system, we can provide up to three options, such as repair, standard replacement, or an upgraded system. That gives you a clear picture of what makes the most sense.
Most full system installs are completed in under 8 hours by our two-person team. In many cases, that means same-day installation. We show up prepared, complete the work carefully, clean the area when we are done, and register your manufacturer warranty after installation. We also back our work with a 1-year labor warranty, with optional extended labor coverage available on qualifying systems.
When you invite an HVAC company into your home, trust matters. We work hard to earn that trust on every job.
We are proud to serve homeowners who want the job done right the first time. That means arriving on time, communicating clearly, and treating your property with respect.
We provide heating and cooling service throughout Lewisville, including areas around Old Town Lewisville, Castle Hills, Indian Oaks, Timber Creek, Vista Ridge, Valley Ridge, and nearby neighborhoods. If you are in Lewisville and your AC is not cooling, your furnace is acting up, or your system is simply getting old, we are ready to help.

He checked all the components inside my house to make sure our air conditioner was working to it full potential. Great company to go with for all your heating and cooling needs."
"Dave Vest has retired and the new owners of N.T.M. Services, Adam and Claudia, couldn't be nicer! Adam came out for pre-season preventive maintenance and recommended I replace the capacitor, which he came back and did 2 days later. The second time he brought Claudia with him to meet me. Having been a customer of N.T.M. Services under Dave for over 25 years, I'm glad that Adam and Claudia will continue the customer service focus I've come to know and appreciate."

"Mike is the most underrated tech in all of DFW. Hands down. Dude was the on call guy on a weekend after hours busy with many clients, and remembered my name and situation from last year after one simple phone call. He gave me a quick rundown of what he thought the problem might be and boom we are shaking and baking once more. #magicmike #talledegamike #ifyouaintfirstyouaintmike"
