A hot office and a failed walk-in cooler need different skills. You need a team that can explain the fault and give a clear quote.
First, ask if the team works on your type of unit. Ask how the job will affect your workday. Find out who will help if the repair does not hold.
These five commercial HVAC companies serve the San Antonio area. Each does work that may fit your needs. Use the table to narrow it down, then compare written bids for the same job.

No. 1: Murray Air Conditioning
La Vernia / San Antonio★4.9(1,001 Google reviews)
A starting point for ongoing HVAC care and rooms that never cool evenly.
If the front office feels fine but the back rooms stay hot, ask about airflow before buying a new unit. Murray’s commercial HVAC team lists zoning and airflow balancing, along with repairs and replacement. That mix puts it first on this list for ongoing care.
The company is based in La Vernia and serves the San Antonio area. Its listed work covers shops, offices and restaurants. Schools, health care sites and buildings with several tenants are also in its scope.
Murray describes a site visit followed by a written scope and price. Bring a floor plan and note when the hot spots occur. Ask what the team checked. Find out how it will test the fix.
The site lists a work guarantee and financing for clients who qualify. Ask for the actual terms with the bid. The care plan should list the tasks it covers, plus any extra fees for an urgent call.
A restaurant may need help with the dining room AC and the walk-in cooler behind the kitchen. Rosenberg’s commercial services cover both, giving the manager one team to call.
It works on rooftop units and split systems. The list also covers chillers and variable refrigerant flow (VRF) systems. Routine care includes filter service and coil cleaning. The company also offers checks when tenants move in or out.
Rosenberg had the most Google reviews among these five in the September 24 snapshot. There is plenty of feedback to read. Some comes from home AC calls.
Share the make and model of any cooler or freezer before booking. Ask if the plan covers that unit. Check the after-hours terms. Decide who can approve work while the manager is away.
Call Comfort-Air for a project that goes beyond one unit. Its specialized systems page lists plant rooms with chilled-water systems or boilers. It also covers make-up air units for commercial kitchens.
Its wider commercial work includes system design and installation. Ask who will lead the design. Find out how the team will test the work.
Bring a list of your units and any plans you have, then ask for a past job like yours. If part of the site will stay open, agree on work zones and when the crew can shut units down.
The Google page covers both Comfort-Air and Primo Plumbing. Some reviews concern plumbing. Look for jobs that match yours. The total does not rate the firm’s HVAC design work.
Written system reports for tenant changes and property sales.

The gap between tenants is a good time to find out what shape the HVAC is in. Air Authority lists written condition reports for tenant changes and property sales. The report tells you the state of the system and the work it needs.
The firm also replaces rooftop units and ducts, offers care plans for each site and fits controls with web access.
For a landlord, a written report gives the next service call a starting point. Ask whether it names each unit and includes photos. For new controls, check that they will work with the equipment you have.
The website brands the business as Air Authority, A Riteway Service Company. Ask who will work at your site and get the name of your main contact before you need an urgent call.
An off-site owner may need proof of the fault before saying yes. Atlas lists photos, videos and clear bills on its San Antonio commercial HVAC page. Those records help the owner choose what to do.
Atlas repairs and replaces systems, including rooftop units. Its page lists service-call and routine-care rates. It says it works within the agreed budget. Ask for a price for each fix. Check when the crew will need to shut off the AC.
Atlas is an option for light commercial work. Confirm your unit sizes when booking. The page’s size limit and one price band do not match. Get the scope for your units in writing.
The BBB complaint record listed four complaints over three years in the September 24 research. That record covers the head office and company-owned branches. Read the complaints and replies together. The count alone tells you little about a job like yours.
Send each team the same details. Include each unit’s brand and model if you know them. Describe the fault and give your work hours. Explain how the crew can reach each unit.
For a replacement, ask what the team will check before choosing the unit size. For a repair, ask how it found the cause. You should be able to follow the bid without knowing the trade.
Ask about
What to get in writing
Work scope
Units covered, the fault found and the proposed fix
Full price
Parts, labor, exclusions and any service-call fee
Site access
Roof access, crane needs and who arranges each step
Business hours
Likely shutdown time and work that can happen while you stay open
Aftercare
Labor warranty, maintenance tasks and after-hours charges
Approval
A spending limit and who must approve extra work
A high star score is a useful starting point. A recent client with a job like yours can tell you more. Ask the person what the crew did when the work changed or a fault came back.
If you manage several sites, agree on how reports and bills will be sent. Decide who can approve an urgent repair. That saves a round of calls when a unit fails on a busy day.
Your next step: Pick two or three teams whose services match your building. Send each the same list of units. Ask for the scope in writing before you choose.
Frequently Asked Questions
Which company should I call for a walk-in cooler or freezer?
Rosenberg explicitly lists walk-in coolers and freezers among its commercial services. Share the make and model when you call. Ask whether cold storage is part of the plan and what happens if the fault occurs after hours.
Who handles uneven cooling in an office?
Murray lists zoning and airflow balancing on its commercial service page. Describe which rooms are hot, when the issue starts and whether it affects the whole floor. Ask the contractor to check airflow before you approve a full replacement.
What should a commercial HVAC quote include?
Ask for the equipment and work scope, with labor and parts shown clearly. Check exclusions and fees for after-hours work. For a replacement, ask about crane access and any duct or controls work. Get the shutdown plan and warranty terms in writing.
Are the Google ratings just for commercial HVAC work?
No. They cover the listed businesses as a whole. Reviews may describe home AC calls or plumbing work. Read recent reviews about jobs like yours and ask for a commercial reference with similar equipment.
How much does commercial HVAC work cost in San Antonio?
The cost depends on the fault, unit size and site access. A service-call fee is not the full repair bill. Ask each contractor for the same scope, then compare the parts, labor and exclusions. For a maintenance plan, ask which repairs and after-hours costs are extra.
