The San Antonio78239 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Outdoor condenser humming but the fan not turning
Short cycling — on and off every few minutes
Frozen evaporator coil or ice on the refrigerant lines
One or two rooms that never reach the set temperature
Heat pump stuck blowing cold air in heating mode
No cool air, or air that is barely cooler than the room
Heating and air conditioning service built around San Antonio
Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm. Across the 78239 area that translates into a steady stream of failed capacitors, clogged filters, dying blower motors and refrigerant leaks — most of which we can diagnose and repair in one visit.
Homes in Bexar County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
The busiest week of our year in San Antonio is the first stretch of sustained march weather. Systems that idled all season fail in clusters.

San Antonio78239 HVAC questions, answered
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in San Antonio, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In San Antonio we see algae and dust clogging drain lines constantly during March through November. It is a fast fix but ignoring it ends in ceiling damage.
Do you service commercial and light commercial properties?
Yes. Around San Antonio we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Are your technicians licensed and insured?
Every technician dispatched into San Antonio is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in San Antonio see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
