Why Choose 3N1 HVAC? Here’s What Our Customers Are Saying

The team from 3N1 HVAC that installed my new system was just awesome. They were incredibly professional and detailed, and explained everything they were doing along the way. Before they left, they made sure I understood everything about my new system, and even registered the warranty for me. I’d recommend 3N1 to anyone who’s looking for a top-notch HVAC company.
Greg R
HONEST, RELIABLE & FAIR! Dealing with Micah was like a breath of fresh air, he presented me with options and NO pressure. The other company’s quotes I received were a complete waste of time.
Nick S
Excellent service, very knowledgeable technicians and totally respectful of your home and property. I highly recommend this company, you will not be disappointed.
Henry B
We lost our A/C when the temperatures were in the high 90s. Called our regular HVAC person. They came out and said we needed a new blower. Could not find one in the US. Quoted a price and ordered one (I assume from China). Waited 10 days, never received blower. Someone recommended 3N1 HVAC. Called them. They came out. Quoted price half of first company. Installed blower next day. Would highly recommend this company.
Martha G
Micah and Danny were awesome. Friendly and attentive to details. They completed the inspection and reported the finding. Micah was great with his former company and now he is creating a company he is proud of. I am impressed and a customer for life.

I’ve been in the home servicing industry for many years and I can’t say enough good things about 3N1 HVAC. I have seen plenty of big box HVAC companies, how they operate, train their associates, and work on homeowners units. Luckily, 3N1 is offsetting these sneaky industry norms and providing homeowners with honest and trusted services. I’m grateful for the team working with me and answering my many questions so that my family and home are comfortable and safe. I would highly recommend 3N1 HVAC to anyone in the surrounding area.
Kirk K
Enjoyed meeting the owner Micah and associate Danny. Discussed the pros and cons of future systems b/c it will be happening for us sooner than later. I look forward to doing business with 3N1HVAC in the years to come.

Delivering Fair and Honest Services, Rooted in Our Family Values

I’m Micah, the owner of 3N1 HVAC. I’ve been fortunate to learn the ropes from Kent Buckalew, a seasoned professional who ran a successful heating and cooling company in the Carolinas for decades. In fact, I’m proud to say I became one of the youngest mechanical contractors in North Carolina. Within just 12 months, I also secured my SC license, NC commercial mechanical license, and a limited electrical license.

My core belief is simple: we aim to deliver fair, honest, and transparent services at reasonable prices. In a world filled with commission-driven and overpriced companies, our mission is to glorify God by providing the best and fairest service possible in everything we do.

Like you, we live and work in this community and consider our customers our friends. We see them at the local ballfields and grocery stores, and truly care about their comfort and well-being. For an HVAC company that always has your best interests in mind, contact our professionals at 3N1 today to schedule an appointment.
