The San Antonio78250 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.
Water pooling around the indoor unit or ceiling stains

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 78250 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.
Around San Antonio, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Heating season here is December through February. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

San Antonio78250 HVAC questions, answered
How often should I change my filter in 78250?
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 much does an HVAC service call cost in 78250?
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.
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.
Why is my system short cycling?
Short cycling in San Antonio most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
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.
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.
