Verified Company
I was referred to Delta T by a friend for a second opinion after a no-heat issue that another HVAC company couldn’t solve and was just throwing parts at. Delta T came out the same day, properly diagnosed the problem, and restored our heat — all for a fair price. I couldn’t be happier, and Delta T is now my primary HVAC company.

Delta T did a great job giving me a run down of the system condition on our 2 units for a home we just purchased. I know Keith the owner very well and see him every week at our networking meeting. These guys are true professionals and gave me clear, expert analysis so we can make the best decisions for our new home. Highly recommend giving them a call.

Dear Cheryl, thank you for your feedback! We're delighted to know you had a positive experience. We're always here to provide excellent service. Your support means a lot to us!
They did a GREAT JOB!! They've replaced my thermostat and my HVAC unit over the last year. Not only were they way cheaper than the other guys I called, they were honest too! I highly recommend them I over any other HVAC company in this area!

I can’t say enough good things about Delta-T NC HVAC of the Triangle. From start to finish they were responsive, professional, and extremely detail-oriented. Their technicians took the time to diagnose the problem correctly, offered honest recommendations, and delivered high-quality work. The level of care and expertise they bring is exceptional. If you want an HVAC company you can trust, Delta-T is the one.

I have worked a lot with Delta T this year. First to replace my AC and furnace, which was an incredible value for what we had done. Since then, also needed our damper motor replaced.
Every time, the team at Delta T has been quick, courteous, and never shy about explaining exactly what’s going on with my HVAC system.
These folks truly are the definition of a neighbor-owned company that looks out for its community. Heck, the owner took my phone call and worked out a plan for me to pay part of the HVAC replacement up front so I could get on the schedule while waiting for my new line of credit to open to pay for the rest.
I can’t recommend Delta T enough. 10/10.

I worked with Delta T NC HVAC to obtain estimates for new HVAC installation. They handled this estimate with clarity and care.”
I was pleased wtih myservice form Delta T. The representative checked our units thoroughly and gave us honest information concerning pricing and the pros and cons of purchasing new units. One thing we did notice is that, despite the thorough check, there was some lack of clarity about the process that occurred after the check and the quote proposal which caused a little confusion as we thought he had left without turning our units back on when in reality he was still at the home but outside waiting to confirm pricing with the company. Overall, though, we were satisfied and would recommend this company in the future to anyone in our area seeking service or pricing estimates. One thing that stood out was the team's professionalism. Although we did not hire this service for our installation, I felt they understood our needs and would support us if necessary to meet them. You can trust this team because they are professional and have systems in place to support sales efficiency. If you want honest feedback about your HVAC situation and quick follow-through, you will gain these things by using Delta T HVAC.
