The San Antonio78240 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.
Heat pump stuck blowing cold air in heating mode

Skyrocketing utility bills with no change in usage
Thermostat reading several degrees off from reality
One or two rooms that never reach the set temperature
Yellow or orange burner flame instead of steady blue
Heating and air conditioning service built around San Antonio
Most of the work we do in San Antonio starts the same way: the system is running but the house is not comfortable. Before we replace anything, we measure airflow, static pressure and temperatures so you are paying for the actual fault.
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 Antonio78240 HVAC questions, answered
What does a new system cost in San Antonio?
A complete residential replacement in the 78240 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.
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.
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.
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.
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.
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.
