Schertz and Cibolo are full of newer homes — and newer homes often come with builder-grade HVAC that's undersized, poorly installed, or already struggling.

Your Home Warranty Isn't Going to Fix This. Here's the Faster Path.
Schertz and Cibolo have some of the newest housing stock in the San Antonio area — and a lot of those homes came with builder-grade HVAC and a home warranty that sounds better than it works.
Home Warranty Route
- 1 Call the warranty company. Wait on hold 20–40 minutes.
- 2 They dispatch an approved contractor — usually 3 to 7 days out.
- 3 Contractor arrives, says the problem is a "pre-existing condition" or "improper installation."
- 4 Warranty company denies the claim. You argue. You're still without AC.
- 5 You're back to square one, days later, in a Texas summer.
Call Couling
- 1 Call (210) 545-0088. A person picks up.
- 2 Tech comes out same day or next day — no waiting on approvals.
- 3 Free diagnosis. Straight explanation of what's wrong — no guessing, no upselling.
- 4 Written price before any work starts. You say yes or no.
- 5 If you say no, you owe nothing. If you say yes, it gets fixed.
If your home warranty does cover it, great — use it. But when it doesn't, or when you can't afford to wait, Couling is the direct path. Same people, same number, since 2007.
The Price You're Told Is the Price You Pay. Every Time.
No number on the estimate that grows once the truck is in your driveway. Couling quotes written prices on every job — whether it's a repair or a new system.
Free to Come Take a Look
No trip fee. No diagnostic charge just to walk through the door. The visit is free — you only pay if you decide to move forward with the work.
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 — no surprises when the invoice arrives.
You Decide — Zero Pressure
"If you want us to do it, great. If not, we leave and you're charged nothing." That's the policy — and it's been the same since 2007.

Newer homes in Schertz and Cibolo often have HVAC systems that were sized to the minimum spec. These symptoms get written off as "just how the house is" — until a summer heatwave turns a minor issue into a full failure.
AC Runs Constantly but Won't Cool Below 80°F
An undersized unit will run non-stop trying to hit a setpoint it can't reach. Common in newer Schertz subdivisions where the builder installed the smallest unit that passed code — not the right size for your layout and heat load.
Inside Feels Sticky Even When the AC Is Running
Air conditioning removes humidity, not just heat. If your home feels like the air outside despite a running system, the unit may be oversized, short-cycling, or the coil may be dirty — all fixable problems.
One Room Is Always Much Hotter Than the Rest
Usually a duct that has come apart inside the wall, a damper stuck closed, or an add-on room that was never properly connected to the system. Couling checks the full system, not just the outdoor unit.
System Kicks On and Off Every Few Minutes
Short-cycling — the unit starts, runs briefly, shuts off, and repeats. It wears out components fast, never fully dehumidifies, and usually signals a refrigerant, airflow, or sizing problem. Not something to ignore through a summer.
Banging, Squealing, or Grinding Sounds
Rattles can mean a loose panel. Banging usually means something has broken inside the blower or compressor. Squealing often points to a worn belt or failing motor bearing. None of these get better on their own.
Electric Bills Noticeably Higher Than Last Year
A system working harder than it should — dirty coils, low refrigerant, a failing capacitor — shows up on your electric bill before it shows up as a complete failure. Catching it early is always cheaper than replacing it in an emergency.
What Happens When You Call Couling
No dispatcher running you between departments. No waiting on a warranty company to approve anything. Four steps — start to finish.
You Call — We Pick Up
Call (210) 545-0088. You reach Couling directly — not a call center, not an answering service. Same-day scheduling is available for most Schertz and Cibolo calls, especially if you call in the morning.
Tech Arrives in Your Window
You get a real arrival window — not an all-day "sometime between 8 and 5." Couling schedules like your time matters, because it does.
Free Diagnosis — Straight Explanation
Your technician looks at the whole system, not just the obvious symptom. You get a plain-language explanation of what's wrong — no technobabble designed to confuse you into approving something you don't need.
Written Price — You Decide
Before any work starts, you see the price in writing. Say yes and it gets fixed. Say no and you owe nothing — no trip fee, no diagnostic charge. The choice is always yours.
5.0 Stars — 61+ Google Reviews
Family-owned since 2007. The reviews are real — and the pattern is the same: free visit, honest diagnosis, written price, no pressure.
"My AC quit on a Friday afternoon. Called Couling and they were out Saturday morning. Tech explained exactly what was wrong, gave me the price in writing, and fixed it in under two hours. Never felt pressured. Will call them every time."
"Home warranty tried to send someone out in five days. Called Couling instead — they came out the next morning, found the problem in 20 minutes, and had it fixed by noon. Honest price, no upsell. Exactly what I needed."
"Our 4-year-old builder system was already struggling. Couling came out, told us it was undersized for our square footage, and gave us options — not a sales pitch. We replaced it with a properly sized Ruud unit and the difference is night and day."
"Called James after another company told me I needed a full system replacement. Couling came out, found it was a failing capacitor — $180 fix. They could have sold me a new unit and I wouldn't have known the difference. That's the kind of company you call back."

Questions Schertz Homeowners Ask Before They Call
Straight answers — no sales angle behind them.
Call Couling directly. You get a free diagnosis, a straight explanation of what's actually wrong, and a written price before any work starts. No waiting on a warranty company to approve a contractor, no disputed claim. If it makes more sense to repair than replace, you'll hear that. If not, you'll hear that too — with the numbers to back it up.
It happens more than you'd expect in newer Schertz and Cibolo subdivisions. Builder-installed systems are often sized to the minimum spec for code — not right-sized for the actual layout and heat load of your specific house. Couling can tell you whether the system is undersized, whether there's a fixable problem, or whether it was simply the wrong unit from the start.
Yes. Couling serves the entire Schertz–Cibolo–Selma corridor. Same free-diagnosis policy, same written price, same same-day availability — it doesn't matter which side of the zip code line you're on.
No. Couling comes out, diagnoses the problem, and tells you exactly what's wrong and what it costs to fix — at no charge for the visit. If you decide not to move forward, you owe nothing. No trip fee, no diagnostic charge just to walk through the door.
Most calls are handled same-day or next-day. Call early and your chances of a same-day slot are good — especially during summer peak months when slots fill fast.
At 12 years with one or two repair calls behind it, you're in the gray zone. Couling gives you both numbers — what the repair costs and what a new system would run — and you decide. No pressure either way. If a repair is genuinely the right call, that's what you'll hear.
A new AC system in the San Antonio area typically ranges from roughly $5,000 to $12,000 depending on home size, efficiency rating, and whether existing ductwork needs attention. Heating systems vary similarly. Every Couling job comes with a written price — the number you're given is the number you pay.
Yes. 10% off repairs for active-duty and veteran military. Just mention it when you call or when your technician arrives — no paperwork required.
