The San Antonio78237 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.
Loud banging on start-up (compressor slugging)
Heat pump stuck blowing cold air in heating mode
Short cycling — on and off every few minutes
No cool air, or air that is barely cooler than the room
Water pooling around the indoor unit or ceiling stains
Breaker trips every time the system starts
Heating and air conditioning service built around San Antonio
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
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.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

San Antonio78237 HVAC questions, answered
How often should I change my filter in 78237?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in San Antonio with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
How quickly can a technician get to San Antonio?
For the 78237 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
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.
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.
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.
How much does an HVAC service call cost in 78237?
A diagnostic visit in San Antonio typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
