- Licensed TDLR Contractor
- 24/7 Availability
Commercial HVAC Services You Can Build a Maintenance Plan Around
Commercial HVAC problems cost more than discomfort — they cost revenue. When an office building loses cooling in July or a restaurant kitchen overheats during dinner service, every hour of downtime hits the bottom line. EMAX HVAC provides commercial HVAC repair, installation, and maintenance for businesses across San Antonio, Texas. We hold an active TDLR license (TACLA158965E), carry full commercial liability insurance, and respond to emergency breakdowns 24 hours a day, 7 days a week.
Whether you manage a single retail location or oversee multiple commercial properties, we treat your system with the same technical precision we bring to every job — because your tenants, employees, and customers depend on it.
Why San Antonio Businesses Trust EMAX HVAC
Licensed and Insured for Commercial Work
EMAX HVAC holds Texas TDLR license TACLA158965E — the same license required for commercial and residential HVAC work in the state. We carry full commercial general liability insurance. Every technician dispatched to your property is covered, and we provide certificates of insurance on request for property managers and building owners who require them.
10 Years of Commercial and Residential Experience
Founded in 2016, EMAX HVAC has spent a decade working on systems across San Antonio — from 2-ton residential splits to multi-zone rooftop units on commercial buildings. That dual experience means we understand both the technical demands of commercial equipment and the service expectations of business owners who cannot afford extended downtime.
All Major Commercial Systems — Not Just Residential Units
Some contractors list “commercial” on their website but only work on small split systems. EMAX HVAC services rooftop units (RTUs), package units, commercial split systems, VRF/VRV systems, make-up air units, and exhaust ventilation. If it heats or cools a commercial space in San Antonio, we work on it.
24/7 Emergency Response for Businesses
A failed HVAC system in a commercial building is not a next-day problem. We answer emergency calls around the clock — nights, weekends, and holidays. When your system goes down during business hours, our goal is to get a technician on site as fast as possible with a stocked service vehicle to minimize your operational disruption.

Commercial HVAC Systems We Service
Rooftop Units (RTUs)
The most common commercial HVAC system in San Antonio. We repair, replace, and maintain single-zone and multi-zone RTUs from Carrier, Trane, Lennox, York, Daikin, and Goodman. If your rooftop unit is short-cycling, leaking refrigerant, or failing to maintain set temperature, we diagnose the root cause — not just the symptom.
Self-contained heating and cooling in one cabinet. Common in strip malls, small offices, and portable buildings. We handle compressor replacements, heat exchanger inspections, economizer repairs, and full unit changeouts when the system reaches end of life.
Larger versions of residential splits, typically serving server rooms, individual suites, or supplemental zones in commercial buildings. We install, repair, and maintain commercial-grade split systems with proper refrigerant charging and duct verification.
Variable Refrigerant Flow systems are increasingly popular in multi-zone commercial buildings — offices, medical facilities, and hotels. EMAX HVAC installs and services VRF systems from Daikin, Mitsubishi, and LG. These systems require specialized training that most residential-focused contractors do not have.
Restaurants, commercial kitchens, and manufacturing spaces require balanced ventilation. We service make-up air units and commercial exhaust systems to maintain proper air pressure, indoor air quality, and code compliance.
Commercial Properties We Serve in San Antonio
EMAX HVAC works with property managers, business owners, and facility directors across property types that each bring specific HVAC challenges:
Offices and Corporate Spaces
Multi-zone temperature control, tenant comfort complaints, and energy management. We help office managers maintain consistent climate across floors and suites without excessive utility costs.
Restaurants and Commercial Kitchens
Kitchen exhaust, make-up air, walk-in cooler adjacency, and high-heat environments make restaurant HVAC uniquely demanding. A cooling failure during service means lost revenue and potential health code issues.
Retail Stores and Strip Malls
RTUs and package units on retail buildings take heavy abuse from San Antonio summers. We keep storefronts comfortable for customers and employees without interrupting business hours.
Warehouses and Industrial Spaces
Large-volume spaces with specific ventilation, humidity, and temperature requirements. We work on warehouse HVAC systems including unit heaters, large-capacity RTUs, and evaporative cooling setups.
Churches, Schools, and Community Buildings
High-occupancy spaces with variable loads — packed on Sunday, empty on Tuesday. These buildings need systems designed for rapid pulldown and energy efficiency during low-occupancy periods.
Multifamily and Apartment Complexes
Property managers with 20, 50, or 100+ units need a contractor who can handle volume, respond to tenant emergencies, and maintain consistency across the property. We offer maintenance agreements built for multifamily operations.
Commercial HVAC Maintenance Plans
Reactive repairs cost more than preventive maintenance — in parts, labor, downtime, and tenant complaints. EMAX HVAC offers preventive maintenance agreements tailored to commercial properties
What a commercial maintenance visit typically includes:
- Full system inspection: electrical connections, refrigerant levels, airflow, thermostat calibration
- Coil cleaning (evaporator and condenser)
- Belt and bearing inspection on RTUs
- Economizer and damper operation check
- Filter replacement
- Condensate drain clearing
- Performance documentation with recommendations
Why it matters for your bottom line: a commercial system running on dirty coils and low refrigerant uses 15–30% more energy than a maintained unit. On a 10-ton RTU running 10 hours a day in a San Antonio summer, that translates to hundreds of dollars per month in excess utility cost.

Commercial HVAC Questions from San Antonio Business Owners
What types of commercial properties does EMAX HVAC service?
We work on offices, restaurants, retail stores, strip malls, warehouses, churches, schools, medical clinics, and multifamily apartment complexes. If your building has a commercial HVAC system, we can service it.
Do you offer preventive maintenance contracts for commercial buildings?
Yes. We offer customized maintenance agreements based on the number of units, system types, and frequency you need. Most commercial clients schedule seasonal maintenance twice a year — once before summer and once before winter. Multifamily and restaurant clients often require quarterly visits. Contact us to build a plan that fits your property.
Can you work on rooftop units?
Rooftop units are one of the most common systems we service in San Antonio commercial properties. We repair, replace, and maintain RTUs from Carrier, Trane, Lennox, York, Daikin, and Goodman — including compressor replacement, economizer repair, and full unit changeouts.
How is commercial HVAC service different from residential?
Commercial systems are larger, more complex, and serve spaces with higher occupancy and stricter code requirements. Rooftop units, VRF systems, and make-up air units require different diagnostic tools and technical knowledge than a residential split system. EMAX HVAC has the training and equipment for both.
Can you schedule maintenance outside of business hours?
Yes. We understand that HVAC maintenance during operating hours disrupts your business. We schedule commercial maintenance on evenings, overnight, or weekends to work around your operations — at no additional charge for off-hours scheduling on maintenance agreement clients.
Do you provide certificates of insurance for commercial jobs?
Yes. We carry full commercial general liability insurance and provide COIs on request. Property management companies and building owners who require contractor insurance documentation before work begins can receive certificates within 24 hours.
What commercial HVAC brands do you work on?
We service all major commercial HVAC manufacturers including Carrier, Trane, Lennox, York, Daikin, Goodman, Rheem, and Mitsubishi. We are not locked into a single brand — we recommend equipment based on your building’s needs and budget, not dealer incentives.
Do you handle HVAC for tenant buildouts and new construction?
Yes. If you are building out a new commercial space or renovating an existing tenant suite, we design and install HVAC systems sized for the specific layout, occupancy, and use case. We coordinate with general contractors and provide submittals and equipment specifications as needed.
