One or two rooms that never reach the set temperature

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 78221 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.
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.
Because Texas runs high-capacity split air conditioning with gas or electric heat, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

San Antonio78221 HVAC questions, answered
What does a new system cost in San Antonio?
A complete residential replacement in the 78221 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.
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.
How quickly can a technician get to San Antonio?
For the 78221 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.
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.
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.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In San Antonio we see algae and dust clogging drain lines constantly during March through November. It is a fast fix but ignoring it ends in ceiling damage.
