The San Antonio78242 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
Dead or bulging run capacitor on the condenser
Pilot light or hot surface igniter failing repeatedly
Heat pump stuck blowing cold air in heating mode
Frozen evaporator coil or ice on the refrigerant lines
Short cycling — on and off every few minutes
Heating and air conditioning service built around San Antonio
If your high-capacity split air conditioning with gas or electric heat has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — San Antonio generates some of the highest call volume we handle in Texas. Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm.
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.
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 Antonio78242 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.
How much does an HVAC service call cost in 78242?
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.
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.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
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.
What does a new system cost in San Antonio?
A complete residential replacement in the 78242 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.
