"Mountain Valley gave a reasonable estimate and did what they said they would do. A/C installed and working great. The installers were super nice - it took them over 8 hours and they never complained once. They interfaced well with the electrician and made sure everything was working properly before leaving. Also they cleaned up and explained everything. Would certainly recommend them."

"Straight forward, knowledgeable, not pushy, very informative. I’ve dealt with some larger HVAC services companies, and I unquestionably prefer to work with Mountain Valley. They focus on addressing your needs rather than trying to sell you something. I like that, will always go back to them for any HVAC service or replacement. And their pricing is very competitive."
