New system, done right

A new AC system, sized and installed right

Replacing an air conditioner isn't an emergency you rush — it's a decision you want to get right. When your system is aging, breaking down, or costing too much to run, Texas Heatwave walks you through your options in plain language and helps you pick a unit that actually fits your home. No overselling, no pressure.

Getting the size right matters more than most people think. An AC that's too big cools in short bursts and leaves rooms humid; one that's too small runs all day and never keeps up. We measure your space, factor in the Texas heat, and match you with a right-sized, efficient system built to handle summers from the Rio Grande Valley to Greater Houston.

Then we install it right — level pads, proper line sets, the correct refrigerant charge, and a clean finish. We handle full system replacements, brand-new installs, and upgrades for both homes and businesses, so the AC you pay for is the AC you actually get.

Repair or replace?

Signs it's time to replace your AC

Not every problem means a new system — but some do. If you're seeing a few of these in your Harlingen or Houston home, a replacement may cost less than one more round of repairs. We'll always give you an honest read before you spend a dollar.

Weak or uneven cooling

Some rooms never get comfortable no matter where you set the thermostat.

Louder every year

New rattles, hums, or a unit that's just noisier often means worn-out parts.

Runs nonstop in summer

An AC that never shuts off is working too hard to keep your home cool.

Sticky, humid air

Older systems struggle to pull humidity, leaving your home muggy and warm.

Rising energy bills

Cooling costs that climb every summer often point to a tired, inefficient system.

Frequent breakdowns

When repair bills start stacking up, a new system can cost less over time.

10–15+ years old

Most air conditioners are near the end of their service life by this age.

Old R-22 refrigerant

Phased-out refrigerant is costly to add, so replacing is often the smarter move.

Questions, answered

AC installation FAQs

Straight answers to what homeowners and businesses across Harlingen and Houston ask most when it's time for a new system.

How much does a new AC system cost?
Every home and system is different, so we don't post a one-size price. After a quick in-home assessment we give you clear options and an upfront quote with no obligation. Call your nearest location to set one up — it's free.
Should I repair or replace my air conditioner?
If your unit is under about 10 years old and the repair is affordable, fixing it usually makes sense. If it's older, breaks down often, uses R-22, or needs a costly part like a compressor, replacement often saves money over time. We'll give you an honest recommendation either way.
What size AC do I need for my home?
The right size depends on your square footage, layout, insulation, and the Texas heat — not just a rule of thumb. We measure your home and run a load calculation so your new system is sized correctly, because an oversized or undersized AC costs you both comfort and money.
How long does an AC installation take?
Most standard residential replacements are finished in a single day. Bigger homes, tricky attic access, ductwork changes, or commercial jobs can take longer — we'll give you a realistic timeline along with your quote.
Which efficiency (SEER2) should I choose?
Higher-efficiency systems cost more up front but use less energy every summer. We walk you through the trade-offs for your budget and how hard you run your AC, so you can pick what makes sense — no upselling.
Do new AC systems come with a warranty?
Yes. New equipment usually comes with a manufacturer warranty on certain parts, and coverage varies by brand and model. Ask us and we'll tell you exactly what your system qualifies for.
Do you install AC for businesses too?
Absolutely. We install and replace AC systems for both homes and businesses across the Rio Grande Valley and Greater Houston — from single residential condensers to rooftop and commercial units.
