Cowboys ranks first for combining urgent response, ongoing care and a wide service menu. Confirm escalation contacts, access requirements, invoicing, service-area charges and authorization limits.
2. Comfort-Air Engineering & Primo Plumbing — Best for Commercial and Mixed-Use Properties
Comfort-Air Engineering & Primo Plumbing provides residential and commercial HVAC and plumbing services in San Antonio. Its commercial capabilities include repair, replacement, maintenance, new-construction installation, specialized systems and indoor-air-quality work.
The company also publishes information about planned commercial maintenance and services for real-estate development. This may suit managers overseeing offices, retail spaces, multifamily communities, mixed-use buildings or properties with more complex mechanical needs.
Ask whether an account manager is assigned, how maintenance is documented and whether trades require separate agreements. Confirm equipment coverage and multi-location approval procedures.
3. Shafer Services Plus — Best for HVAC and Plumbing Coordination
Shafer Services Plus advertises residential and commercial heating, cooling, plumbing and drain services across San Antonio and surrounding areas. Its service information includes repair, installation, system replacement, maintenance plans and emergency support.
The multi-trade structure may benefit managers who want fewer vendor relationships for common comfort and plumbing issues. It can also simplify coordination when a problem crosses systems, such as condensate drainage, water damage near mechanical equipment or work requiring both HVAC and plumbing review.
Confirm which division handles each request, whether separate licenses and invoices apply, and how after-hours work is authorized.
4. ASC Heating & Air — Best for HVAC-Focused Residential and Light-Commercial Work
ASC Heating & Air provides air-conditioning and heating repair, installation and maintenance for San Antonio homes and commercial businesses. Its service menu includes air conditioners, furnaces and heat pumps, along with preventive maintenance plans.

Verify commercial equipment capabilities, emergency availability, service boundaries and account billing. For replacements, request sizing, equipment, efficiency and warranty details.
5. Rosenberg Plumbing & Air — Best for Direct Communication and Broad Home-System Service
Rosenberg Plumbing & Air offers AC repair, installation and maintenance, heating services, indoor-air-quality work, plumbing and commercial service in San Antonio. Its public information emphasizes that callers speak with a person rather than a recording and that repair pricing is provided upfront.
That communication approach may appeal to managers who need clear dispatch information and repair expectations before authorizing work. Its combination of HVAC and plumbing can also be useful for residential rentals or smaller mixed portfolios.
Confirm the commercial scope, response process, account contacts and visit documentation. Ask whether estimates can be separated by property, unit and work order.
What Should Property Managers Compare Before Choosing an HVAC Vendor?
Use the same checklist for every provider:
- Active Texas licensing and insurance
- Residential and commercial equipment capabilities
- Geographic coverage for every managed property
- Emergency dispatch and escalation procedures
- Standard authorization limits for repairs
- Itemized estimates and approval requirements
- Maintenance scope, frequency and inspection reports
- Unit-level, building-level and portfolio-level invoicing
- Tenant communication and property-access procedures
- Manufacturer, labor and workmanship warranties
- Permitting and code-compliance responsibilities
- Equipment history and service-record retention
- Primary and backup account contacts
A property-management agreement should also explain who may approve work, when emergency repairs can proceed without advance authorization and how photos, diagnoses, invoices and warranty records will be delivered.
Which HVAC Provider Is the Best Fit for a Property Portfolio?
Cowboys Air Conditioning & Heating is the top overall selection for managers seeking 24/7 availability, broad HVAC capabilities and service across San Antonio and nearby counties. Comfort-Air may be a strong comparison for commercial or development-related work. Shafer offers HVAC and plumbing coordination, ASC provides focused heating and cooling service, and Rosenberg emphasizes direct communication alongside HVAC and plumbing.

Frequently Asked QuestionsWhat HVAC information should a property manager keep for each building?
Keep equipment make, model, serial number, age, location, filter size, warranty documents, service history, maintenance schedule and access instructions. Store permits and replacement records with the property file.
Should a property manager use one HVAC company for every property?
Not always. One provider can simplify records and communication, but a portfolio may need backup coverage for emergencies, distant service areas, specialized equipment or large commercial systems.
What should an HVAC maintenance report include?
The report should identify the property and equipment, work completed, measurements, observed defects, recommended actions, replaced parts and the technician’s service date. Photos can improve documentation.
How should after-hours HVAC repairs be authorized?
Create written thresholds defining who can approve dispatch, diagnosis, temporary work and permanent repair. Include escalation contacts, tenant-access instructions and documentation requirements.
