The San Antonio78257 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.
Yellow or orange burner flame instead of steady blue
Refrigerant leak at a flare or coil connection
Heat pump stuck blowing cold air in heating mode
Outdoor condenser humming but the fan not turning
Loud banging on start-up (compressor slugging)
Dead or bulging run capacitor on the condenser
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. Our San Antonio teams are set up for exactly that: rapid response, flat-rate pricing quoted before work begins, and no surprise overtime charge for nights or weekends.
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.
Peak cooling demand here runs March through November. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

What San Antonio homeowners say

— Marcus T., verified San Antonio customer
San Antonio78257 HVAC questions, answered
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.
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.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Texas, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
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.
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.
