Commercial HVAC in San Antonio, TX

Commercial HVAC is a different animal from residential work. The equipment is larger, the systems are more complex, the load requirements vary by industry and occupancy, and the cost of downtime is real — measured in lost revenue, uncomfortable customers, or staff who can't work in an environment that's 85 degrees in August.

Above & Beyond Air Conditioning & Heating serves commercial clients across San Antonio and surrounding areas — offices, restaurants, retail, warehouses, medical facilities, schools, and more. We handle installation, repair, replacement, and maintenance on all major commercial system types and brands.

We serve San Antonio, Helotes, Bulverde, Canyon Lake, New Braunfels, Schertz, and Cibolo.

Commercial AC Repair

When a commercial AC system goes down in San Antonio summer heat, every hour matters. A hot building affects employee productivity, drives customers out the door, and in some industries — food service, healthcare, data-sensitive environments — can create compliance or safety issues fast.

We respond to commercial AC repair calls with the same urgency the situation demands. Our service vehicles carry common commercial parts, and most repairs can be diagnosed and resolved in a single visit.

Common commercial AC problems we repair:

Inconsistent temperatures across zones or floors
Rooftop unit failures
Refrigerant leaks
Compressor issues
Failing blower motors or condenser fans
Thermostat and control system malfunctions
Reduced airflow from ductwork problems or clogged filters
Electrical faults — capacitors, contactors, wiring

We provide transparent estimates after diagnosis, before any work begins. Emergency service is available 24/7 for critical failures — we understand that commercial HVAC problems don't wait for business hours.

Commercial AC Installation

Installing a commercial AC system correctly from day one prevents years of performance problems, inefficiency, and premature failures. The most common cause of commercial AC problems we diagnose isn't equipment failure — it's improper sizing or installation from the start.

We begin every commercial installation with a proper load calculation — analyzing your building's square footage, occupancy patterns, equipment heat loads, insulation, ceiling height, and ventilation requirements before recommending any equipment. Oversized systems short-cycle and create humidity problems. Undersized systems run constantly and never catch up on peak days.

What we handle:

Rooftop units (RTUs)
Split systems
Packaged systems
VRF (variable refrigerant flow) systems
Ductwork design and installation
Zoning systems and controls
Permit applications and inspections

We coordinate with contractors, facility managers, and building owners to schedule installations that minimize disruption to operations. All installations are permitted, inspected, and backed by manufacturer warranties. Financing is available at 0% interest for qualified applicants.

Commercial AC Replacement

At some point, repairing an aging commercial system stops making financial sense. When repair costs are accumulating, the system is struggling to keep up with demand, or energy bills have climbed significantly without a usage change, replacement usually delivers better long-term value than continued repair.

When replacement makes sense:

System is over 15 years old with increasing repair frequency
Annual repair costs approach 50% of replacement cost
The system uses R-22 refrigerant, which is no longer manufactured and increasingly expensive to source
The building's cooling load has grown beyond the system's capacity
Energy consumption is significantly higher than modern equivalents

Modern commercial systems offer 30–50% better energy efficiency than equipment from 15+ years ago. That difference shows up on your utility bill every month. We provide detailed side-by-side comparisons of repair cost vs. replacement cost with projected energy savings so you can make an informed decision.

We handle full removal of old equipment, installation of new systems, permit and inspection coordination, and staff training on new controls — all with scheduling designed to minimize business disruption.

Commercial Heating & Furnace Repair

San Antonio winters are short but not trivial — especially for businesses open early morning or late evening when temperatures drop fastest, or for facilities where staff safety and comfort is a liability concern.

Commercial furnace problems show up differently than residential ones. Uneven heat across a large space, a yellow or flickering burner flame, unexplained spikes in gas or electric bills, or a system that runs constantly without reaching set temperature all signal issues that need professional diagnosis — not just a thermostat adjustment.

We repair commercial:

Gas furnaces (all major brands)
Electric furnaces
Rooftop heat units
Heat pumps in commercial applications
Burner, ignition, and flame sensor issues
Heat exchanger inspections (cracks are a CO safety concern)
Blower motor and airflow problems
Thermostat and control system failures

Gas odors or carbon monoxide detector alarms in a commercial building require immediate evacuation and emergency response — not a service ticket. Call us and call 911.

Commercial HVAC Maintenance

Commercial HVAC systems run harder and longer than residential equipment — and the consequences of unexpected failure are more significant. A planned maintenance program is the most cost-effective way to protect that equipment and avoid the disruption of emergency repairs.

We recommend at minimum two service visits per year — once in spring before the cooling season and once in fall before heating season. High-use facilities, restaurants, medical spaces, and data environments benefit from more frequent service.

Standard commercial maintenance includes:

Full system inspection — indoor and outdoor units
Coil cleaning (evaporator and condenser)
Refrigerant level check
Electrical connections inspection and tightening
Capacitor and contactor testing
Filter replacement
Thermostat calibration and control testing
Ductwork inspection for leaks
Drain line inspection and clearing
Burner and heat exchanger inspection (heating season)
Full performance test and documentation

We provide detailed service reports after every visit and can structure maintenance agreements around your schedule — including off-hours service for businesses that can't afford downtime during operating hours. Maintenance agreement clients receive priority scheduling and preferred pricing on repairs.

Industries We Serve

Offices and Professional Buildings

Office environments need consistent temperatures across diverse spaces — open work areas, conference rooms, private offices, server rooms. We design and maintain systems that handle variable occupancy throughout the day while optimizing energy use during nights and weekends. Multi-tenant buildings get particular attention to zone control and proper distribution.

Restaurants and Hospitality

Food service demands more from HVAC than almost any other commercial environment — kitchen heat loads, ventilation for cooking odors and grease, humidity management in dining areas, and reliable operation 365 days a year. We understand the stakes when a system goes down mid-service, and we respond accordingly.

Retail Stores and Shopping Centers

Retail comfort directly affects how long customers stay and whether they come back. Consistent temperatures, proper humidity control, and quiet operation are all factors. We work around retail hours and accommodate the specific challenges of high-traffic entryways and large display windows.

Industrial and Warehouse Facilities

Large square footage, high ceilings, equipment heat loads, and worker safety requirements make industrial HVAC a specialized discipline. We handle high-volume air movement systems and industrial-grade cooling solutions calibrated to the demands of each facility.

Medical Facilities and Clinics

Healthcare HVAC has strict requirements — filtration standards, pressurization, temperature consistency, and redundancy. We maintain current training on healthcare-specific standards and understand the consequences of system failure in patient care environments. No guesswork, no shortcuts.

Schools and Educational Facilities

Academic facilities have complex scheduling — classrooms, gymnasiums, labs, auditoriums — and HVAC decisions that directly affect student health and learning. We schedule major service work during breaks and unoccupied periods, and we design systems with energy efficiency in mind given the budget constraints common in education.

Churches and Houses of Worship

Religious facilities present unique challenges — intermittent use, large open spaces that need to transition from unoccupied to full capacity quickly, and often historic structures where equipment placement requires creativity. Quiet operation during services is non-negotiable. We've solved these problems before.

What We Service

We work on all major commercial system types and brands, including:

System types: Rooftop units, split systems, packaged units, VRF systems, chillers, heat pumps, commercial boilers, and air handlers.

Brands: Trane, Carrier, Lennox, Goodman, York, Daikin, Mitsubishi, and others.

If it heats or cools a commercial space in San Antonio, we work on it.
