Commercial HVAC Services

Commercial HVAC Installation and Replacement

Choosing the right system is one of the most important decisions a business owner or property manager will make. Oversized equipment wastes energy and short-cycles. Undersized systems struggle to maintain temperature and wear out quickly. Our installation process begins with load calculations, airflow evaluation, and operational needs so the equipment fits the building, not just the square footage.

We install systems for:

• Office buildings
  
• Retail centers
  
• Restaurants and food service facilities
  
• Medical offices and clinics
  
• Warehouses and distribution centers
  
• Educational facilities
  
• Multi-tenant commercial properties
  

Our team evaluates occupancy levels, lighting heat load, equipment heat generation, ceiling height, and ventilation requirements. This allows us to recommend equipment designed for consistent comfort and predictable operating costs.

When replacement is necessary, we coordinate the project to minimize disruption to business operations. Scheduling, crane placement, electrical tie-ins, and system commissioning are handled in an organized process so your building returns to normal operation as quickly as possible.

Rooftop Units (RTU) Service and Installation

Rooftop units are among the most common commercial HVAC systems. RTUs combine heating, cooling, and ventilation into a single cabinet installed on the roof, making them efficient and space-saving for commercial buildings. However, because they operate outdoors year-round and run for long hours, they require proper maintenance and experienced service.

We provide full RTU support including:

• Installation and system replacement
  
• Economizer repair and calibration
  
• Heat exchanger inspection
  
• Refrigerant diagnostics and leak detection
  
• Blower motor and belt service
  
• Control board troubleshooting
  
• Airflow balancing and ventilation adjustments
  

RTU failures often develop gradually. Reduced airflow, uneven temperatures, or rising energy bills are usually early warning signs. Our technicians inspect electrical components, coils, and dampers to identify performance issues before they become emergency shutdowns.

We also verify economizer operation. A properly functioning economizer brings in outside air for cooling when conditions allow, significantly reducing energy consumption. Many commercial systems lose this feature due to failed sensors or stuck dampers, and the building ends up cooling mechanically when it doesn’t need to.

Package Unit Expertise

Package units are similar to rooftop units but may be installed at ground level or on platforms adjacent to the building. These systems house all major components—compressor, evaporator, condenser, and heating section—in one enclosure. Because everything is integrated, proper setup and airflow configuration are critical.

Our package unit services include:

• New equipment installation
  
• Heating and cooling diagnostics
  
• Gas heating section service
  
• Condensate drainage correction
  
• Coil cleaning and restoration
  
• Static pressure and airflow testing
  

Package units often serve open commercial spaces such as retail stores and large offices. If airflow is restricted or improperly balanced, certain areas become uncomfortable while others overcool. We measure duct static pressure and adjust fan speeds and dampers to stabilize temperatures across the space.

We also check combustion safety for gas heating sections, verifying ignition performance, gas pressure, and venting operation. This helps maintain safe indoor air conditions while preventing premature heat exchanger failure.

Commercial HVAC Repairs

Unexpected downtime affects revenue, employee productivity, and customer satisfaction. Our repair services focus on accurate diagnostics rather than trial-and-error part replacement. We test system components individually to identify root causes.

Common commercial HVAC issues we repair include:

• Compressor failures
  
• Refrigerant leaks
  
• Frozen evaporator coils
  
• Electrical faults and tripped breakers
  
• Thermostat and control malfunctions
  
• Poor airflow and duct restrictions
  
• Intermittent system shutdowns
  

We carry common commercial parts and coordinate sourcing for specialized components when needed. Our goal is to restore operation quickly while preventing recurring breakdowns.

Preventive Maintenance Programs

Commercial HVAC systems run significantly longer hours than residential equipment. Without maintenance, efficiency drops and parts fail prematurely. A preventive maintenance program helps stabilize operating costs and reduces emergency repairs.

Routine service visits typically include:

• Filter replacement
  
• Coil cleaning
  
• Electrical inspection
  
• Refrigerant level verification
  
• Motor lubrication
  
• Belt and pulley adjustment
  
• Safety control testing
  
• Thermostat calibration
  

Maintenance also helps extend equipment life. Many systems fail early not because of age but due to neglected airflow or electrical wear. Scheduled inspections allow us to correct small issues before they damage compressors or heat exchangers.

Commercial Controls and Thermostats

Modern buildings rely on control systems to manage temperature, ventilation, and scheduling. Improper programming often leads to wasted energy and occupant complaints. We configure and service commercial thermostats and building control interfaces to ensure systems operate only when needed.

We assist with:

• Programmable thermostat setup
  
• Multi-zone control balancing
  
• Occupancy scheduling
  
• Sensor calibration
  
• Temperature consistency correction
  

Even minor control adjustments can significantly reduce operating costs, particularly in buildings with varying occupancy hours.

Indoor Air Quality for Commercial Spaces

Indoor air quality affects employee health, customer comfort, and regulatory compliance. Poor ventilation or filtration can contribute to odors, dust accumulation, and airborne irritants. Our commercial air quality services improve circulation and filtration without overloading the HVAC system.

Solutions include:

• High-efficiency filtration systems
  
• Ventilation balancing
  
• Fresh air intake adjustments
  
• Humidity management
  
• Air purification equipment
  

We ensure the building receives adequate outside air while maintaining stable temperatures and energy efficiency.

Emergency Commercial HVAC Service

Commercial equipment failures rarely occur at convenient times. When systems shut down, the building environment can quickly become unsafe for occupants or sensitive equipment. TemperaturePro San Antonio provides responsive service to restore operation and stabilize conditions.

Our technicians troubleshoot electrical systems, controls, compressors, and airflow components to quickly identify the source of failure. When immediate full repair is not possible, we implement temporary solutions to keep the building operational while parts are secured.

Our Service Approach

We work closely with facility managers, property owners, and business operators to simplify HVAC management. Every service call includes system performance feedback and recommendations so you understand your equipment condition.

Our commercial service philosophy emphasizes:

• Accurate diagnostics
  
• Transparent recommendations
  
• Preventive maintenance planning
  
• Equipment longevity
  
• Operational efficiency
  

Whether you operate a single building or manage multiple properties, our team provides structured service that helps you anticipate needs rather than react to failures.

For dependable commercial heating and cooling support, TemperaturePro San Antonio delivers installation, repair, and maintenance services designed to keep your building operating consistently and efficiently.
