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 78248 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.
Because Texas swings between seasons quickly, a lot of our San Antonio calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
The busiest week of our year in San Antonio is the first stretch of sustained march weather. Systems that idled all season fail in clusters.

San Antonio78248 HVAC questions, answered
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
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 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.
How often should I change my filter in 78248?
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 brands do you service in San Antonio?
All of them. Our 78248 technicians are trained on Mitsubishi Electric, Daikin, Bryant, Rheem 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.
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.
