Our old central air/heat system drew its last breath recently and it was time to replace the 30+-year-old system and ductwork. I appreciate an owner/manager was responsible for the quoting and checked on the quality of the installed work. The team on site was awesome. Professional and courteous they made the difference. For a middle-class homeowner, this is a big investment and I would recommend Nash and team without hesitation.

After my A/C suddenly went out one afternoon in mid-August, I called Nash Heating & Air Conditioning and by the next morning it was fixed and back to normal. Greg was a consummate professional and friendly, while quickly diagnosing the problem and fixing it. I highly recommend Nash Heating and AC.

Devon and Anthony came and replaced the ducts and plenums in our house. They were prompt, courteous, professional, and knowledgeable. They completed their job in a timely manner and cleaned up their work area. They also explained the work they were doing and answered any questions we had. We highly recommend them for any heating and ac work.
