The San Antonio78245 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.
Frozen evaporator coil or ice on the refrigerant lines

Heating and air conditioning service built around San Antonio
We treat 78245 as a dedicated service zone. Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm. Because the equipment here works hard for a long season, we lean heavily on catch-it-early diagnostics rather than emergency replacements.
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 Antonio78245 HVAC questions, answered
How often should I change my filter in 78245?
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 78245 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.
What brands do you service in San Antonio?
All of them. Our 78245 technicians are trained on Heil, York, Daikin, Lennox and essentially every other residential brand sold in Texas, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
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 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.
