Heating and air conditioning service built around San Antonio
We treat 78204 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.
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.

San Antonio78204 HVAC questions, answered
How often should I change my filter in 78204?
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.
What does a new system cost in San Antonio?
A complete residential replacement in the 78204 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
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.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Texas is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Do you offer maintenance plans?
We do. A two-visit plan in Texas covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
What brands do you service in San Antonio?
All of them. Our 78204 technicians are trained on Mitsubishi Electric, Heil, Rheem, Trane 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.
