Real Texas Plumbing - Heating and Air is a family-owned HVAC and plumbing company at 20811 Dawn Drive in Lago Vista, with a second location in Lakeway. When your AC quits, we prioritize no-cooling calls for homes in Lago Vista, Jonestown, The Hollows, Point Venture and Lakeway. Call early and we’ll do everything we can to get to you the same day.
An AC emergency is no cooling when the heat is a risk to someone in your home, water coming from the unit, or a burning smell or breaker that won’t stay on.
Call right away if
Your AC isn’t cooling and someone at home is an infant, an older adult, or has a medical condition
Water is leaking from the indoor unit or through the ceiling
You smell burning
The breaker keeps tripping
Can it wait until the next opening?
Usually yes if the air is just a little warm, the weather is mild, or the system is noisy but still cooling. Don’t keep running a system that’s icing up or tripping its breaker.
Set the thermostat to COOL, below room temperature. If the display is blank, try fresh batteries.
Check the breaker once. If it trips again, leave it off and call us.
Look at the air filter. If you can’t see light through it, swap it.
See water around the indoor unit? Turn the system off to protect your ceiling.
Ice on the coil? Set the thermostat to OFF and the fan to ON so it can thaw.
Smell burning or see sparks? Turn it off at the thermostat and the breaker, then call us.
If anyone in the house is at risk from the heat, move them somewhere cool while you wait.
The visit starts at a $65 trip charge, which we apply toward the repair when you schedule. After we test the system, you get a written price before we touch anything.
What changes the price
Parts, the kind of failure, and the age of the system. A capacitor or a clogged drain line costs far less than a blower motor or a refrigerant leak.
Repair or replace?
If your AC is 12+ years old and the repair is a big one, we’ll quote the repair and a replacement side by side and tell you which we’d choose in your house. See AC replacement.
If the AC runs but some rooms stay hot, the problem is often leaky or disconnected ducts in the attic. See air duct repair.
Emergency calls get priority, and we’ll do everything we can to get to you the same day. Call early. Our phones are answered Monday–Friday 7:30 AM–8 PM and Saturday 8 AM–noon.
We don’t dispatch overnight. If your AC stops after we close, use the steps above, move anyone at risk from the heat somewhere cool, and call us when we open. Call early and we’ll do everything we can to get to you the same day.
Lost heat instead of cooling? See our emergency heating repair page for furnace and heat pump safety steps.
You call or text. We ask what the system is doing and give you safe steps to take until we arrive.
We test the whole system. Thermostat, capacitor, contactor, refrigerant pressures, airflow, coils and the drain line, on both the indoor and outdoor units.
You get the answer and the price. We tell you what failed, and you get a written price before any work begins.
We repair it and prove it. We confirm the fix with real measurements: temperature split, pressures, amp draw and airflow.
Cooling season here runs April into October with long stretches over 100 degrees. In August heat, a failed capacitor is the part we replace most. Humid attics keep condensate drain lines busy, and hillside homes around the lake often cool unevenly. We work across Bar-K Ranches, Tessera, Highland Lake Estates, The Hollows, Point Venture and Jonestown. For the full list of common AC problems, see our AC repair page.
“Scheduling was quick and easy. Derek came out and got my AC back up and running in no time.” — Matt S.
“Same day service. Replaced the capacitor. Fast, reliable.” — Erik
“...laid out the solution clearly without any high-pressure sales pitch.” — Karina M.
When you contact Real Texas Plumbing - Heating and Air for emergency AC repair, we quickly ask about airflow, thermostat issues, warm air, strange noises, water leaks, or a frozen unit. That helps us prioritize the call, give a realistic arrival window, and prepare the right tools and common parts before we head out.
Once on site, we inspect the full cooling system, including the condenser, evaporator coil, electrical components, drain line, and refrigerant levels, to pinpoint the failure. We explain what caused the breakdown, what needs immediate attention, and provide an honest repair recommendation before any work starts.
After your approval, we complete the repair using proven methods and quality parts, then test system performance, temperature split, airflow, and safety controls to make sure the AC is cooling properly. Before we leave, we walk you through the fix, answer questions, and make sure the job area is clean and complete.
