AC Repair in Terrell Hills, TX
Terrell Hills is its own incorporated city, wrapped entirely by San Antonio and about 5 miles from our shop. Smart Choice Heating and Cooling repairs air conditioning here every week, and we work these houses for what they are. The median home dates to 1957, and only 105 units in the whole city have been built since 2010, so square footage here has grown by addition rather than replacement. We are family owned, licensed by the Texas Department of Licensing and Regulation, TACLB 103516E, with NATE certified technicians available 24/7.
We repair every major brand of air conditioning equipment, Amana, Goodman, Carrier, Trane, Lennox, Rheem, and more, in Terrell Hills homes where an addition was tied into ductwork laid out in the 1950s.
With almost no new construction since 2010, this city adds rooms instead. When new space hangs off the original duct trunk, distribution is usually the fault we find.
Why one added room stays warm while the rest of the house is fine
Terrell Hills was finished in a single push. American Community Survey Table B25034 for Terrell Hills city, Texas counts 1,962 housing units, of which 778 were completed between 1950 and 1959 and 1,217, or 62.0 percent, stood before the decade turned. Only 105 units, 5.4 percent of the total, date from 2010 or later.
The Census counts the year a building went up, not what happened to it later, so the next part is ours to say. What we see on these calls is a primary suite off the back, a family room where a porch used to be, a bedroom over the garage.
What we find behind that work is new space fed from the trunk line already in the attic, with a branch added and nothing else reworked. The branch is long, or narrow, or both. The thermostat, meanwhile, still hangs in the older part of the plan, so it reaches setpoint and stops the blower while the newer rooms are still climbing.
A homeowner reads that as an air conditioner too small for the square footage, and a bigger one looks like the obvious remedy. It is the expensive wrong answer, because added capacity still has to travel the same narrow path. We measure what each room receives before anyone talks about equipment.
What we do about it
We start in the room you called about. An AC repair visit here begins at the vent that is losing, not at the condenser, because a complaint that follows one room around is seldom a failed component.
We look at supply and return as one path. A long run to a newer room sheds air at every joint, and a space with no way to send air back will not hold a temperature. Duct sealing recovers more here than a parts swap does.
We can put the capacity where the shortfall actually is. A ductless mini split head serves a converted garage or a sunroom directly, on its own thermostat, and asks nothing further of ductwork laid out seventy years ago.
We check the cold months on the same trip. One blower and one duct system carry both seasons, so the room that lags in August is normally the room that stays chilly in January. Heating repair gets looked at with the cooling side, and our contact page is where to tell us which rooms to watch.
What Terrell Hills homeowners tell us
Two mini split heads, finished inside a day
V had two ductless heads put into a home, the same fix we often propose for an added space here. The work ran on schedule with the owner, Alonzo, on site.
“Highly recommend!! We did 2 mini-splits for a residential home. Alonzo and his team made this experience smooth and easy. Very professional, on-time for appts, great response time when called or text, and entire staff is kind, knowledgeable, honest, listened and honored our requests without a problem. Best thing was price was incredible and warranty great. We spent less than expected and still received a top of line product. Very thankful how quickly and professionally they got the job done within 1 day.”
A two head job landing inside one day is what we plan for. Cost and warranty terms follow the equipment and the scope, so both are on paper before anyone opens a wall.
An agent puts her referrals on the line
Rachael sends clients to us, so a job she refers carries her name as well as ours. Agents working houses of this vintage field hard questions from buyers.
“As a dedicated real estate agent, I understand the importance of recommending reliable service providers to my clients, especially when it comes to their HVAC needs. Smart Choice AC and Heating, led by Alonzo Martinez and his team, has consistently proven to be a trustworthy and professional company in San Antonio and the surrounding areas. Their commitment to providing quick and effective solutions for my clients, as well as their willingness to guide individuals through any HVAC issues, has been truly commendable. I am confident in continuing to recommend their services to my clients and look forward to utilizing their expertise in my own new home.”
Referral work holds us to a plain standard. Explain the system, show the readings, quote what the building needs, whether an agent sent you or not.

Signs You Need AC Repair
Addition Runs Hot
A room added to a 1950s plan and fed off the original trunk rarely gets the air it needs.
Upstairs Never Cools
Space added above an older house sits several degrees warmer than the floor below it.
Blowing Warm Air
When no vent in the house blows cold, the fault sits at the equipment and not in the ductwork.
Strange Noises
Metallic grinding or a squeal at startup traces to a worn bearing, a blower motor or a contactor.
Humid Indoor Air
Air that feels clammy at 74 degrees means the system is not pulling moisture out.
High Energy Bills
A system straining to reach added rooms runs longer and costs more on the same setting.
Repair or Replace? We Show You the Math
Repair if:
The equipment is sound, the part is available, and the repair costs a fraction of replacement. A comfort complaint in an added room is rarely the condenser.
Consider replacement if:
The system is past 15 years, uses R-22, or has been repaired repeatedly. In a 1950s house that has grown, we start from a load calculation for the building as it stands today and correct distribution with it, because new equipment on the same trunk repeats the same complaint.
Our AC Repair Process
Real appointment windows
We give you a window we can keep and call before we arrive. Terrell Hills is about 5 miles out, so a no cooling call gets same day attention, at any hour.
Complete diagnostic, measured
We check charge, electrical, drainage and controls, then measure static pressure and room by room delivery. That step matters most here. A house that gained square footage long after its ducts were drawn will look short on capacity when it is really short on delivery, and only measurement separates the two.
Upfront options in plain English
You get a written price before work starts, the replacement figure beside it when both apply, and a zoning or mini split option costed out when that is the better answer.
Repair done right, mess cleaned up
We finish the repair, verify airflow and temperature split in the rooms you called us about, and leave the work area clean.

Frequently Asked Questions
Do you really cover Terrell Hills?
Yes. Terrell Hills is about 5 miles from our shop off Perrin Beitel, one of the closest cities we serve. We answer calls 24/7 and reach most no cooling calls same day.
Why does one room never cool?
In a house of this era it is usually a later addition fed off the original duct trunk. The branch is too small or too long for the load, so we measure delivery first.
Will a bigger system fix it?
Usually not. Oversized equipment short cycles, removes less humidity, and still cannot push air down a branch never sized for that room. Distribution is the actual fix.
Do you install ductless mini splits?
We do. For an addition or a converted space, a mini split head or a zoned setup treats that area as its own load rather than straining ductwork laid out in the 1950s.
Should I repair or replace my AC?
That depends on age, refrigerant and repair history. We quote both, and in a house that has been added onto we price the distribution work with it so the comparison is real.
