Commercial AC repair, installation & maintenance in North Texas
North Texas summers are unforgiving. When a commercial AC system goes down in July or August, it doesn't just create discomfort — it drives customers out, disrupts operations, and in some environments creates safety concerns. Rock Hard Refrigeration provides commercial air conditioning services built for the demands of commercial facilities throughout North Texas.
We service all types of commercial AC systems — rooftop package units that serve retail centers and restaurants, commercial split systems for offices and multi-zone buildings, and ductless mini-splits for server rooms, additions, and spaces that need individual temperature control. Our HVAC license (TACLA113168C) covers the full scope of commercial AC work, and our technicians come prepared with diagnostic tools and OEM parts to resolve most issues on the first visit.
Commercial AC services we offer
Commercial AC systems we service
We work on every type of commercial air conditioning equipment throughout North Texas — from single-zone units to multi-system commercial HVAC installations.
Aftermarket AC parts may cost less upfront but often fail sooner and can void manufacturer warranties. We stock and source OEM components for Trane, Carrier, Lennox, and all major commercial HVAC brands so your system performs reliably after every repair we complete.
Common commercial AC repairs we perform
Our technicians carry diagnostic equipment and OEM parts for the most frequent commercial AC failures, resolving most issues on the first visit.
Commercial AC maintenance in North Texas
Commercial AC systems that aren't maintained fail at the worst possible times — peak summer heat, maximum occupancy, your busiest week of the year. A pre-season maintenance visit in spring catches failing components, dirty coils, low refrigerant, and worn belts before they shut your system down in the middle of July.
Our commercial maintenance memberships include scheduled AC preventative maintenance visits covering refrigerant level checks, coil cleaning, electrical inspection, capacitor and contactor testing, filter service, and full system performance verification. Priority scheduling and discounted repair rates are included.
Texas summers don't wait — neither should your AC repair
North Texas averages over 100 days above 90°F each year. When a commercial AC system fails during peak summer, you're not dealing with a comfort issue — you're dealing with a business continuity issue. Staff can't work efficiently, customers leave, perishable inventory is at risk, and in some facilities, you're facing compliance problems.
Rock Hard prioritizes commercial AC emergencies. We dispatch fast, arrive with parts, and focus on first-visit resolution. For businesses that can't afford extended downtime, that's the difference between a disruption and a disaster.
The commercial AC contractor North Texas businesses trust
We don't service residential systems. Every AC call we take is commercial — which means faster diagnosis, deeper equipment knowledge, and less wasted time explaining what your system is to a technician who mostly works on residential units.
