Heating done right

Warm, reliable heat for homes and businesses

When a norther rolls through and the heat won't turn on, a house gets uncomfortable fast. Texas Heatwave gets a real technician to your door, finds why your furnace or heat pump quit, and fixes it for a fair price — no guesswork, no upselling. We keep homes and businesses warm across Harlingen and Houston.

We handle the whole range of heating trouble: a furnace that won't ignite, a heat pump blowing cool air, weak or uneven warmth, short cycling, strange smells, or a system that keeps tripping the breaker. If your system is past saving, we'll walk you through a new furnace or heat pump honestly — sized and matched to fit your home.

Our team works on all major furnace and heat pump brands, gas and electric, for both homes and commercial spaces from the Rio Grande Valley up to Greater Houston. Same family-owned crew, same honest service, on both sides of Texas.

Signs it's time to call

Signs your heater needs service

Heating systems usually warn you before they quit on the coldest night. Catch these early and a small fix stays small. Notice any of these in your Harlingen or Houston home? Give us a call.

Blowing cool air

The system runs but the air from the vents never really warms up.

Strange noises

Banging, rattling, or squealing when the heat kicks on points to a worn part.

Burning smell

A burning or acrid odor when the heat starts shouldn't be ignored.

Weak or uneven heat

Some rooms stay cold while others feel fine — a sign something's off.

Rising energy bills

Heating costs that jump each winter can mean the system is straining.

Short cycling

The heater turns on and off over and over without warming the room.

Won't turn on

No response when you call for heat usually points to an ignition or electrical fault.

Yellow burner flame

A yellow (not blue) gas flame can signal a combustion problem — call us right away.

Our tech checks the full heating system — ignition, gas or electric heat, airflow, and controls — to find the real cause, not just the symptom.

You get a plain-English rundown of what's wrong and a clear price before any work starts. Repair or replace, it's your call.

With your go-ahead, we make the repair with quality parts, or install your new furnace or heat pump — sized right and done clean.

Questions, answered

Heating FAQs

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

Why is my heater blowing cold air?
A few things can cause it: a heat pump stuck in the wrong mode, a furnace that isn't igniting, a dirty filter choking airflow, or a thermostat setting. Our tech checks the whole system, finds the real cause, and explains your options before any work.
Should I repair or replace my furnace or heat pump?
If your system is under about 10 to 15 years old and the repair is affordable, fixing it usually makes sense. If it's older, breaks down often, or needs a costly part, we'll walk you through a new system honestly — with no pressure either way.
Do you install heat pumps and gas furnaces?
Yes. We install and replace both gas and electric furnaces and heat pumps for homes and businesses across the Rio Grande Valley and Greater Houston, sized right for your space.
How much does heating repair or a new furnace cost?
Every system and problem is different, so we don't quote a flat price sight unseen. After we diagnose the issue or measure for a new system, you get a clear, upfront price before any work begins. Call your nearest location for a free quote.
Do you offer same-day heating repair?
Often, yes — especially during a cold snap when heat matters most. We move fast on no-heat calls across Harlingen and Houston; call early in the day for the best shot at a same-day slot.
Is a strange smell from my heater dangerous?
A dusty smell on the first cold day is normal and usually burns off. But a persistent burning, electrical, or gas-like odor is not — shut the system off and call us right away so we can check it safely.
Do you guarantee your heating work?
We back small repairs with a 100% satisfaction guarantee and 30 days of labor coverage. Certain parts may carry a manufacturer warranty — ask us and we'll tell you if your part qualifies.
