Our Story

Diamondback AC, Heating & Refrigeration is a locally owned and operated HVAC-R company in La Vernia, Texas. In addition to HVAC services, Diamondback also provides Electrical and Sheet Metal Services.

We have been providing quality heating, ventilation, air conditioning, and commercial refrigeration services for Wilson County, Bexar County, and surrounding areas for years. We take pride in providing the best for our customers by being licensed technicians who ensure quality driven work and courteous, professional service. We provide the highest quality workmanship in new installations, service, repair, and replacements of all major brands of residential and commercial Heating and Cooling systems. As we work hard to maintain our relationships with customers, we find the more they need, the more we have been willing to dedicate ourselves to the craft of our trade. HVAC demands much more than just what it is, hence why we also have an Electrical and Sheet Metals division to provide a full range of services. Whatever the demands of your request or HVAC system might need, we’re able to complete it all.

We are certified air conditioning and heating professionals, as well as can maintain commercial refrigeration setups. We maintain a high level of quality among our staff. All of our installers and technicians are trained on a regular, on-going basis. We don’t like duplication of efforts and by expanding our service lines to include electrical services and sheet metals, we’re able to foresee that a job is completed properly from start to finish, without error.
