Comfort built on trust, one neighbor at a time.
We're a family-owned, licensed HVAC team serving Sierra Vista, Hereford & all of Cochise County — with honest pricing, expert work, and service you can count on day or night.
Two daughters. One family business.
The N in N & M and the M in N & M are the first initials of Monce and Mayra's two daughters. The business is named for them, because it was built for them — owning something of their own, helping people, and making a life here in Cochise County was a dream Monce and Mayra shared long before they started it in 2022.
Monce is the founder, owner and lead technician, with 20 years in HVAC, and he is still the one on service calls and installations. Mayra runs the office. When you call N & M, you are talking to the family whose name is on the truck — not a call center, and not someone who will hand you off.
What that means in practice: honest recommendations, fair pricing and quality workmanship. We won't tell you to replace a system when a repair makes sense. Where your comfort is our priority.
