Specialized HVAC Services in San Antonio

Commercial Refrigeration Services

Our commercial refrigeration expertise covers every aspect of cold storage and food service equipment. For restaurants, we service walk-in coolers and freezers, reach-in refrigerators, prep tables, ice machines, and display cases. For grocery and retail, we maintain refrigerated display cases, walk-in coolers, frozen food storage, and specialty refrigeration. Common issues we repair include refrigerant leaks, compressor failures, thermostat malfunctions, door seal problems, evaporator coil icing, and drainage issues. We stock refrigerants and common parts on our service vehicles to minimize downtime. Emergency refrigeration service is available 24/7 because we understand equipment failure can mean thousands of dollars in spoiled inventory.

HVAC Duct Cleaning

Professional duct cleaning removes years of accumulated dust, debris, allergens, and contaminants from your HVAC ductwork. Our process begins with a thorough inspection using cameras to assess duct condition and contamination levels. We then use powerful HEPA-filtered vacuum systems and rotary brushes to dislodge and remove buildup from every duct, plenum, and vent. Special attention goes to return air ducts where the most debris accumulates. After cleaning, we sanitize ducts to eliminate mold, bacteria, and odors. We also clean or replace air filters and inspect the system for leaks or damage. Benefits include improved indoor air quality, reduced allergy symptoms, better HVAC efficiency, and elimination of musty odors.

Indoor Air Quality (IAQ) Solutions

Indoor air can be 2-5 times more polluted than outdoor air due to trapped allergens, dust, pet dander, mold spores, VOCs from cleaning products, and cooking fumes. Our IAQ solutions address these issues with proven technology. Whole-home air purifiers integrate with your HVAC system to filter out particles, allergens, and odors from every room. UV germicidal lights installed in ductwork kill mold, bacteria, and viruses before they circulate. HEPA filtration captures 99.97% of airborne particles down to 0.3 microns. Humidity control systems prevent excess moisture that encourages mold growth or dry air that irritates respiratory systems. We start with air quality testing to identify your specific concerns, then recommend targeted solutions that fit your budget and health goals.

Smart Thermostats

Smart thermostats replace outdated manual or programmable thermostats with Wi-Fi-connected devices that learn your schedule, optimize energy use, and provide remote control via smartphone apps. Popular models like Nest Learning Thermostat, Ecobee SmartThermostat, and Honeywell Home T9 offer features including adaptive scheduling that learns when you're home and away, geofencing that adjusts temperature based on your phone's location, energy reports showing usage and savings, voice control via Alexa or Google Assistant, and zoned control when paired with multiple sensors. Installation typically takes 1-2 hours. Our technicians ensure compatibility with your HVAC system, proper wiring, Wi-Fi connection, and complete programming. Most customers see 10-23% reduction in heating and cooling costs within the first year.

Ductless Mini-Split Systems

Ductless mini-split systems provide efficient heating and cooling for spaces without existing ductwork—perfect for room additions, converted garages, workshops, or homes where installing ducts is impractical. Each system consists of an outdoor compressor unit and one or more indoor air handlers mounted on walls or ceilings. Benefits include zone control (different temperatures in different rooms), high energy efficiency (no duct losses), quiet operation, easy installation without major construction, and both heating and cooling capability. Popular brands we install include Mitsubishi Electric, Daikin, LG, and Fujitsu. Applications include sunrooms and additions, garage workshops, converted attics, older homes without ductwork, and supplemental cooling for hot spots. Installation requires only a small hole through the wall for refrigerant lines and electrical connections.

24/7 Emergency Service

Call (210) 501-9445 anytime—nights, weekends, holidays—and reach a live person, not an answering service. Our on-call technicians respond quickly with fully stocked service vehicles ready to diagnose and repair most issues on the first visit. We prioritize emergency calls for restaurants, food service businesses, and critical refrigeration failures that threaten inventory or business operations.
