Our Air Conditioning Services
A strange noise, warm air blowing from the vents, or a unit that won’t turn on — whatever the issue, we diagnose it accurately and fix it right the first time. We repair all residential AC brands and models, from older R-22 systems to the latest high-efficiency units.
Installing a new air conditioning system is one of the biggest investments in your home. We help you choose the right unit based on your home’s square footage, insulation, ductwork, and cooling needs — then install it with precision so it runs efficiently from day one. We install central AC systems, split systems, and package units from every major manufacturer.
San Antonio heat puts extreme stress on AC systems. A yearly tune-up catches worn parts, low refrigerant, dirty coils, and electrical issues before they turn into expensive repairs. Our maintenance visits include a full system inspection, filter check, refrigerant level verification, and performance testing.
Heat pumps provide both cooling and heating in one system — an efficient option for San Antonio’s climate where extreme cold is rare but summer cooling runs eight months or more. We install, repair, and maintain all heat pump brands, including air-source and ductless heat pump systems.
When your AC breaks down at night, on a weekend, or during a 100°F afternoon, you can’t wait until Monday. EMAX HVAC offers emergency air conditioning repair in San Antonio — call 210-920-1412, and we’ll work to get a technician to your home as fast as possible.
Ductless mini-split systems are the solution for homes without existing ductwork, room additions, converted garages, or spaces where traditional central AC can’t reach. We install single-zone and multi-zone ductless systems that let you control the temperature in each room independently — and they run quieter and more efficiently than window units.

FAQs About Air Conditioning in San Antonio Tx
How often should I schedule AC maintenance in San Antonio?
At least once a year, ideally in early spring before the summer heat arrives. San Antonio AC systems run heavily from April through October, so catching issues early prevents mid-summer breakdowns and extends the life of your unit.
What's the difference between central AC and a ductless mini-split system?
Central AC uses ductwork to cool your entire home from a single unit. Ductless mini-splits cool individual rooms without ducts — ideal for home additions, converted garages, or older homes without duct infrastructure. We install and service both types.
How do I know if I need AC repair or a full replacement?
If your AC is under 10 years old and the repair costs less than half the price of a new unit, repair usually makes sense. If it’s over 12 years old, needs frequent repairs, or uses R-22 refrigerant (which is phased out), replacement is typically more cost-effective. We’ll give you an honest recommendation during your free estimate.
Can you replace my old AC system and haul away the old one?
Yes. When we install a new air conditioning system, we remove and dispose of the old unit as part of the job. You don’t need to arrange separate hauling or disposal.
