Your technician diagnoses the problem at no charge — no trip fee, no $65 diagnostic just to walk through the door. If you don't want to move forward, you owe nothing and we leave.
Written Price, Every Time
Before a single part comes off your system, you see the price in writing. What you're told is what you pay — nothing grows after the truck is already in your driveway.
You Decide — Zero Pressure
If you decide not to move forward, you're charged nothing. "If you want us to do it, great. If not, we leave and you're charged nothing." That's been the policy since 2007 — and it's still true.

Universal City summers are brutal and the cold fronts don't give much warning. These are the signals worth acting on before a manageable problem turns into a full breakdown — and a much bigger bill.
Unusual Noises — Banging, Grinding, Squealing
A healthy system runs quietly in the background. Banging often means a loose or broken component. Grinding points to a motor bearing under stress. Squealing is usually a belt issue. None of these fix themselves — and they tend to get worse fast in the Texas heat.
Warm Air Coming From the Vents
If your AC is running but the air feels lukewarm — or outright warm — the system isn't doing its job. Low refrigerant, a failed compressor, or blocked airflow are the usual causes. Each one needs a technician, not a filter change.
Ice on the Lines or Outdoor Unit
Ice on refrigerant lines or the outdoor unit means something is wrong — blocked airflow, low refrigerant, or the system running in conditions it can't handle. Shut it off and call. Running it iced up damages the compressor, and compressors are expensive.
Short-Cycling — On and Off Every Few Minutes
A system that starts, runs briefly, shuts off, and restarts repeatedly isn't just annoying — it's a warning sign. Dirty filter, low refrigerant, an oversized system, or a control board problem can all cause it. The faster you catch it, the less damage gets done.
Electric Bill Spiked With No Change in Habits
Same thermostat settings, same household routines — but the bill jumped. That's almost always a system working harder than it should. Refrigerant leak, a worn motor, or restricted airflow are common culprits. Catching it early costs less than letting it run degraded all summer.
Certain Rooms Always Hot or Cold
Uneven temperatures in Universal City homes often trace back to a duct that has come loose in a wall cavity, a damper problem, or a system that was never sized right for the home's layout. Couling looks at the whole system — not just the outdoor unit.
Recognize any of these? The visit is free — and so is the diagnosis.
Call (210) 545-0088Repair It or Replace It? Here's the Honest Framework
This is one of the biggest financial decisions your home puts in front of you. You'll get a straight recommendation during the free visit — here's the framework so you come in knowing what questions to ask.
Usually Worth Repairing
When fixing it makes financial sense
- System is under 10 years old and this is the first significant breakdown
- Repair cost is under half the price of a comparable new system
- The system runs efficiently between breakdowns
- The failed component isn't the compressor or heat exchanger
Probably Time to Replace
When a new system pays off faster
- System is 12+ years old with two or more repair calls in the last couple of summers
- Still running on R-22 refrigerant — phased out, and replacement is expensive
- Compressor has failed — the single most expensive component on the unit
- Energy bills have climbed steadily even between repair calls
Here's Exactly What Happens When You Call Couling
Every call to a new HVAC company involves some uncertainty. Here's what the process looks like from the moment you reach out to the moment your home is back to normal.
You Call or Request Online
Tell us what's going on — AC not cooling, heat won't kick on, or you want a quote on a new system. We schedule a real arrival window, not "sometime between 8am and 5pm." Your time is worth more than that.
Free Diagnosis — No Charge Just to Look
Your technician diagnoses the problem and explains it in plain language — not HVAC jargon. You hear exactly what's wrong, why it happened, and what it takes to fix it. The diagnosis costs nothing, no matter what.
Written Price Before Any Work Starts
Before a single part is touched, you see the number in writing. You decide whether to move forward. If you say no, you owe nothing — no trip fee, no diagnostic charge. That policy hasn't changed since 2007.
Work Done Right — Usually in One Visit
Most AC repairs and heating repairs are completed the same day. New systems are scheduled promptly, right-sized for your Universal City home — no mess left behind, no "we'll have to come back for the rest."
5.0 Stars from 61+ Google Reviews — A Few Examples
These are real reviews from real customers. The full list is on Google.
"James runs a different type of HVAC company — one that doesn't nickel and dime you for every issue. He found and fixed a thermostat problem that the previous company wanted to charge us hundreds for. Didn't charge us a dime."
"We've used Couling AC & Heating exclusively for almost 30 years. James, Orlando and crew have always been prompt, courteous and honest. Recently had our 25+ year old system replaced — very pleased with the quality, workmanship and price."
"James provides the absolute best customer service one could ask for. We've had him out to the house multiple times — always arrives on time, treats us with courtesy, and never tries to make unnecessary charges. Found our go-to HVAC company."
"James and his team are the best. Over the years they maintained our old HVAC unit and later replaced it with a brand new system. James is always responsive to any requests and provides honest advice. Can't recommend them enough."
Six Reasons Universal City Homeowners Keep Coming Back
Plenty of HVAC companies serve the northeast San Antonio corridor. Here's what makes Couling different in ways that actually matter when it's 98° and your AC is out.
Free Visit — No Trip Fee, Ever
Many HVAC companies charge $65–$95 just to show up. Couling comes out, diagnoses the problem, explains it in plain language — no charge. If you decide not to proceed, you owe nothing and we leave.
Written Price Before Any Work Starts
You'll never hear "once we got into it, it turned out to be more." The price you see in writing is the price you pay. What's quoted is what's charged — no additions after the truck is in your driveway.
Same-Day Service — Real Arrival Windows
When your AC is out in a Texas July, an all-day wait isn't acceptable. Couling gives you an actual arrival window and shows up in it. You get your day back.
10% Military Discount — Active-Duty & Veterans
Universal City is home to a large military community. Couling gives 10% off repairs for active-duty and veteran military — just mention it when you call or when the technician arrives. No paperwork, no hoops.
Family-Owned Since 2007 — Not a Franchise
James Couling runs the business. Your system history stays with the same owner and the same team. No rotating crew of strangers, no franchise upsell playbook — just the same people every time you call.
50 Years of HVAC Expertise Since 1976
James has been in the HVAC industry since 1976 — through every refrigerant transition, efficiency standard, and heat pump generation the San Antonio market has seen. That depth shows in the diagnosis.
Questions Universal City Homeowners Ask Before They Call
Straight answers — no hedging, no sales pitch.
No. Couling comes out and diagnoses the problem at no charge — no trip fee, no diagnostic charge just to walk in the door. You get a straight explanation of what's wrong and a written price before any work starts. If you decide not to move forward, you owe nothing.
Most calls are handled same-day or next-day. Couling schedules real arrival windows — not all-day waits. The sooner you call, the better the odds of a same-day slot during peak summer months.
Rough rule: if it's under 10 years old and this is the first real repair, fix it. If it's over 12 with two or three repair calls in the last couple of summers, replacement may be the smarter money. You'll get an honest read during the free visit — including the times a repair is clearly the right call.
Usually one of three things: a duct that has come open and is leaking conditioned air into a wall cavity, a damper issue, or a system that was never sized right for your home's layout. Couling diagnoses the whole system — not just the outdoor unit.
A furnace burns gas and produces intense heat fast. A heat pump moves heat rather than creating it — more efficient in mild weather, less effective in prolonged hard freezes. For most San Antonio-area winters, a heat pump performs well. For homes that see multiple hard-freeze weeks, a dual-fuel system or gas furnace may be the better fit. You'll get a recommendation based on your home, not what's easiest to install.
A new AC system in the San Antonio area typically ranges from roughly $5,000 to $12,000 depending on your home's size, the efficiency rating, and whether existing ductwork needs attention. Heating systems vary similarly. Couling gives written pricing on every job — no estimates that grow after the truck arrives.
Yes. Couling gives 10% off repairs for active-duty and veteran military. Universal City has one of the highest concentrations of military families in the area — just mention the discount when you call or when your technician arrives.
A cracked heat exchanger is the primary CO risk in a gas furnace — and it's exactly what Couling checks during every heating service call. Ruud furnaces Couling installs carry a Limited Lifetime Heat Exchanger Warranty. If your furnace hasn't been looked at recently, a safety check before the cold months is worth doing.
