Commercial and Industrial HVAC Maintenance in San Antonio, TX
Your rooftop units work hardest when the Texas heat peaks, and so do your walk-in coolers. Diamondback keeps both running with custom maintenance agreements for businesses in San Antonio, New Braunfels and the towns within 30 miles.
Downtime Costs More Than Maintenance
A broken unit in July does not wait for a slow week. A dead walk-in can spoil a full load of stock overnight. A hot sales floor sends shoppers out the door.
Preventive maintenance finds the worn belt, the low charge or the clogged coil before it shuts you down. Our licensed, background-checked techs fix small problems on a set schedule. That means fewer emergency calls and fewer surprise bills.
What We Maintain
Rooftop Units
Rooftop units sit in direct sun all summer, and the heat wears down compressors, fan motors and belts. On each visit we check refrigerant charge, clean coils, test motors and look for gaps at the roof curb and ductwork. Clean coils and a correct charge let the unit cool the same space in less run time. That cuts energy waste and puts less strain on parts.
Commercial Refrigeration and Walk-Ins
Walk-in coolers, walk-in freezers and reach-in units run around the clock. We check door seals and gaskets, clean condenser coils, watch temperature control and test defrost cycles. A torn gasket or a dirty coil makes the compressor run longer. Catch it early and you protect the equipment and the food inside it.

Industrial HVAC Systems
Warehouses, plants and large facilities run high-capacity systems that cost real money to replace. We build a maintenance schedule around your hours and your equipment. Our crew also builds custom ductwork and vents in-house when a fix calls for it.

Who We Work With
Property Managers
You handle tenants, budgets and work orders. You need an HVAC partner who shows up on schedule and sends clear notes after every visit. We work directly with your facility team and can cover several properties under one agreement.
Restaurants
Your kitchen and your walk-in cannot go down on a Friday night. We schedule visits around service hours and keep refrigeration and cooling on the same agreement.
Retail Stores
Customers notice a warm store. We keep rooftop units and split systems tuned so your sales floor stays comfortable. Chains with more than one location can put every site into one agreement.
Industrial Facilities
Large systems need regular care to reach their full service life. We plan visits around shifts and production so maintenance doesn’t slow your work.
Custom Scheduled Maintenance Agreements
Every site is different. One store might have 4 rooftop units, while a warehouse might have 30 or more. That’s why we build each agreement around the equipment you actually have.
Two Major Inspections a Year
Your agreement follows the maintenance schedule each manufacturer recommends for your HVAC and refrigeration equipment. We come out for two major inspections a year, one every six months.
Minor Repairs During Your Visit
Our techs can handle minor repairs during each scheduled visit, up to a set limit per system. Anything bigger gets a written request first, and you approve it before we start.
Records That Protect Your Warranties
We record every inspection. Many manufacturers require yearly maintenance to keep parts warranties valid, and our records give you proof the work was done.
Lower Repair Costs
Agreement customers get 5% off repairs during the agreement year. You also get a locked-in labor rate for any service or repairs after maintenance.
Flexible Payment
You can pay for the year up front, twice a year, quarterly or monthly. Agreements renew each year unless you cancel before the renewal date.
Make Your Equipment Last Longer
Most equipment fails early for the same few reasons. Dirt builds up on coils. Belts stretch. Refrigerant leaks slowly. Electrical parts wear out.
None of this shows up on day one. It adds up over the years. Regular service catches each problem while it’s still a cheap fix, so your rooftop units and walk-ins last longer and the big replacement bill gets pushed further out.
