When you can't wait

Fast help when your HVAC fails

An AC that quits during a Texas heat wave — or a heater that dies in a hard freeze — is more than an inconvenience. It's a real problem for your family, your customers, or your crew. Texas Heatwave treats it that way, moving your call to the front of the line and getting a technician out fast.

We handle both cooling and heating emergencies for homes and businesses: no cool air, no heat, a system that won't turn on, burning smells, a breaker that keeps tripping, or water pouring from the indoor unit. We diagnose quickly, tell you straight what's wrong, and get you comfortable again as fast as we safely can.

Our team covers the Rio Grande Valley and Greater Houston six days a week, and we do our best to reach urgent calls the same day. Call early and call fast — the sooner we know, the sooner we're on the way.

HVAC emergencies we handle

If you're dealing with any of these in your Harlingen or Houston home or business, don't wait it out — call us and we'll move your repair to the front of the line.

No cool air

Your AC runs but blows warm, or won't cool at all, in the middle of the heat.

Loud bang or grinding

A sudden loud noise usually means a part has failed and needs attention now.

No heat

The furnace or heat pump won't warm the house during a hard freeze.

Water or flooding

Water pouring from the indoor unit can damage your home fast.

Business system down

A failed commercial system putting your business or tenants on hold.

Breaker keeps tripping

A breaker that pops again and again points to an electrical fault — shut it off.

Won't turn on

The system is completely dead and won't respond when you call for heat or cool.

Burning smell

A burning or electrical odor means shut the system off and call us right away.

Fixed on the spot

Questions, answered

Emergency HVAC FAQs

Straight answers to the emergency questions we hear most from homeowners and businesses across Harlingen and Houston.

What counts as an HVAC emergency?
No cool air in extreme heat, no heat in a freeze, a burning or electrical smell, water pouring from the unit, or a breaker that keeps tripping — anything unsafe or that can't wait. If you're not sure, call and we'll help you figure it out.
How fast can you get to me?
We treat emergencies as top priority and do our best to reach you the same day. Our teams run Monday through Saturday across Harlingen and Houston — call early in the day for the quickest response.
Should I turn my system off in an emergency?
If you smell burning, see smoke or sparks, hear a loud bang, or see water pooling, yes — shut it off at the breaker and call us. Running a failing system can turn a small repair into a bigger, costlier problem.
What can I do while I wait for the tech?
Turn the system off at the thermostat, keep family and pets out of extreme temperatures, and clear access to the indoor and outdoor units so we can get right to work when we arrive.
How much does an emergency call cost?
It depends on what's wrong. Our tech diagnoses the issue fast and gives you a clear, upfront price before any work begins — no surprises. Call your nearest location and we'll get moving.
Do you handle both AC and heating emergencies?
Yes. We respond to cooling and heating failures — AC, heat pumps, and furnaces — for homes and businesses across the Rio Grande Valley and Greater Houston.
Do you take commercial emergency calls?
Yes. We service commercial and rooftop systems as well as homes, so if your business loses cooling or heat, call us and we'll prioritize getting you back up and running.
