What Our Customers Say About Us
Common AC Repairs We Handle
After years of Central Texas summers, we've seen just about every way an air conditioner can fail — and most of them are fixable a lot faster (and cheaper) than people fear. Here's what we repair most often:
Refrigerant leaks and low charge
If your AC is running but barely cooling, you're often low on refrigerant — and that almost always means a leak somewhere, not just "needs a top-off." We find the leak, fix it properly, and recharge to manufacturer spec, so you're not back to square one in a month.
Failed capacitors and contactors
These are the small electrical parts that start your system every cycle, and they're the single most common repair we make. In the Texas heat they wear out fast. The good news: it's usually a same-visit, affordable fix.
Frozen evaporator coils
Ice on your indoor unit looks dramatic but the cause is usually simple — restricted airflow from a dirty filter or a refrigerant issue. We thaw it, find the real cause, and fix that, instead of just scraping ice and sending you a bill.
Compressor problems
The compressor is the heart of your system. When it struggles, we'll give you a straight answer on whether it's worth repairing or whether you're better off putting that money toward a replacement — no upsell, just the honest math.
Blower motor and fan failures
If air isn't moving, even a perfectly charged system can't cool your home. We diagnose whether it's the motor, the capacitor that runs it, or a control board issue.
Thermostat and control issues
Sometimes the "broken AC" is actually a thermostat that's mis-wired, failing, or just set wrong. We check the cheap stuff first — because you shouldn't pay for a compressor diagnosis when it's a $20 part.
Furnace & Heater Repair
Usually the AC repair involves some work on the Air Handling Unit (AHU) or completing furnace repairs. No worry, our experts can fix the problem regardless of where the culprit hides!
Whatever's wrong, we diagnose it accurately, explain it in plain English, and show you the price before we touch a wrench.

Signs Your AC Needs Repair
A struggling air conditioner doesn’t always stop working completely — sometimes it sends early warning signs that a breakdown is coming. Catching these issues early can save you from more expensive repairs and keep your home comfortable through the Texas heat.
Watch for these common indicators:
- Warm air coming from vents – Your system may be low on refrigerant or have a compressor issue.
- Weak or inconsistent airflow – Often caused by a clogged filter, duct problems, or a failing blower motor.
- Unusual noises – Grinding, banging, or squealing sounds can mean loose or damaged components.
- Higher energy bills – A sudden spike often means your AC is working harder than it should.
- Leaks or moisture around the unit – This could be refrigerant or drainage issues that need immediate attention.
If you notice any of these signs, it’s best to have a professional inspect your system as soon as possible. Small problems left unchecked can quickly turn into major repairs, especially during peak summer heat in Austin.
Repair or Replace? We'll Give You the Honest Answer
Nobody likes being told they need a whole new system when they called about a repair — and you've probably heard horror stories about companies that push replacement on every call. That's not how we operate.
When we diagnose your system, we'll tell you honestly whether a repair makes sense or whether you'd be throwing good money after bad. A good rule of thumb: if the repair costs less than a third of a new system and your unit is under about 10 years old, repair is usually the smart move. If your system is older, on R-22 (the old, expensive refrigerant), or facing a major component failure like the compressor, we'll lay out both options with real numbers and let you decide.
And because our replacement prices are posted right on our site, you can see exactly what the alternative would cost before you make the call — no sales presentation required. And if replacement is the call, the most important thing to get right is the size — here's how to size an AC for your home, and why bigger isn't better. See our AC replacement pricing →
