OLD SYSTEMS WEAR OUT FASTER HERE
Cooling season in Harlingen stretches past nine months. Ecotech Heating & Cooling sizes replacement systems for that kind of run time.



Signs Your System Is Ready to Retire
Nobody replaces an air conditioner for the fun of it. The decision creeps up over a couple of summers, and by the time somebody lands on a page like this one, they’ve usually got a hunch already.
Two or three of those together and repairs quit paying for themselves. Our AC Installation page covers what comes next.
When Replacement Beats Repair
Most air conditioners down here give you somewhere between twelve and fifteen good years, and the run time in this climate shortens that rather than stretching it. System age by itself doesn’t settle the question, but once a unit crosses that mark the parts inside are all wearing out at about the same pace.
Refrigerant settles a lot of arguments. Units built before 2010 mostly run on R-22, which stopped being produced years ago, so a leak means paying steep money for something nobody manufactures anymore.
Then there’s what the system already costs you. Rising bills with no change in how you live usually mean the compressor is straining for less cooling than it used to give. Add two or three service visits in one season and the gap between fixing and replacing gets pretty thin.
Right-Sizing Your System
Sizing is where a changeout goes right or wrong, and it has little to do with whatever was bolted down before. We run a Manual J load calculation, which is a room by room measurement of the house: square footage, ceiling height, window area and direction, insulation, and how leaky the place is. That math hands us the tonnage your home actually needs.
Oversizing is the classic mistake in this part of Texas. Equipment that’s too big hits the set temperature in a hurry, shuts off, and never runs long enough to pull moisture out of the air, so the house ends up cold and clammy at the same time. Right-sized equipment holds longer cycles, dries things out, and costs less to run.
SEER2 and Real Savings
SEER2 is a mileage rating for air conditioners: the higher the number, the less electricity a system burns moving the same heat out of the house. Stepping up a tier costs more on install day and hands it back every month afterward, and with a cooling season this long the payback shows up faster than it would up north.
Here’s what a full replacement covers:
None of it pays off if the pieces don’t belong together. A matched system means the outdoor unit and the indoor coil were engineered as a pair and tested to hit their rated numbers. We’re an authorized Ruud dealer, and we install Goodman and Lennox too, so you get a couple of real options priced side by side.
Who You’re Hiring for the Job
Anthony Longoria has swung tools in this trade since 2008, and he put his own name on Ecotech Heating & Cooling in 2018. That history counts for more on a replacement than it does on a small repair. The man who measures your house is the same one on the ladder install day, and the same one who picks up the phone two years later.
The 60+ Google reviews on our profile keep circling back to fair pricing and honest bids, which is about the best thing a homeowner can say about a contractor. Licensing and insurance are in place, the crew carries EPA certification, and our satisfaction guarantee stands behind the workmanship. Financing is available with approved credit.
Replacements Around the Valley
Our address is 1525 S H St, so a job in town is usually a ten minute drive from the bay door. Treasure Hills and Stone Pine have whole streets of houses built in the same stretch of years, which means the original equipment in them ages out around the same time.
We handle changeouts in Combes, Santa Rosa, Mercedes, Weslaco and San Benito as well. Those homes get the same load calculation and the same equipment choices as a job three blocks from the shop.
A lot of Valley homes sit empty for part of the year. Winter Texan owners often book the changeout for the off season, which is easier on everybody, and we can run the whole job with a key, a set of photos and a phone call north.
Get Your Free Estimate
A quote from us starts with a walkthrough, not a price sheet. We look at the ductwork, the electrical, where the equipment sits and how the rooms lay out, then we put numbers on paper. What you get back lists the model, the tonnage and the total, and it costs you nothing.
Utility and manufacturer rebate programs come and go around here, so we won’t quote you a number nobody can back up. What we will do is flag whatever your particular install qualifies for at the time we write it up, in plain language on the page.
The office runs Monday through Friday, 8:00 AM to 5:00 PM. Ring (956) 970-0814 or send your details over from the contact page, and we’ll set up a walkthrough.
What Customers Say After the Install
Replacement customers tend to write about what install day was actually like, and whether the final bill matched the paper. Over 60 Google reviews in, we’re glad to let those do the talking. One example:
“Our fifteen year old unit finally quit and Ecotech had a new Ruud running by the following week. Anthony measured the house first instead of guessing, and the back bedrooms actually cool now. Price matched the quote.”
Replacement Jobs We Ran

Every one of these started as a house with equipment past saving. Old gear out, pad leveled, new line set run, refrigerant charged by weight, and airflow read at the registers before anybody packs up the truck.
Curious how a Central AC Installation actually goes, start to finish? Ask for the photo set from a house near yours with similar square footage. Seeing the old unit parked next to the new one settles most doubts.
You ask. We answer
Units start around $2,800 installed and climb from there. What moves the number is tonnage, the SEER2 tier you pick, single-stage against variable-speed, the shape your ductwork is in, whether the line set gets replaced, and how hard the equipment is to reach. Financing is available with approved credit.
Honestly, plenty of systems are worth fixing. Under about ten years old with a bad capacitor or contactor, repair it and move on. Once a compressor fails on a unit past twelve, or a repair quote climbs toward a third of a new install, the money goes further on replacement.
We run a Manual J load calculation instead of copying whatever is stamped on the old unit. It accounts for square footage, ceiling height, window area, insulation and which way the house faces, then gives us the tonnage that fits. Plenty of the homes we look at are running a size larger than they need.
It is. R-22 production ended in 2020, so what remains comes from recovered stock at a price that keeps climbing. A leak on one of those systems can cost more to recharge than the equipment is worth, and that alone pushes a lot of Valley homeowners toward a new system.
Most straight changeouts wrap in a single day. We pull the old equipment in the morning, set the new condenser and air handler, run the connections, pressure test, charge by weight and check airflow before leaving. Figure on a second day if the ductwork or the electrical isn’t ready for it.
We’re an authorized Ruud dealer, so that line is what we know best and what we stock. Goodman and Lennox go in too, when a homeowner asks for one or the budget points that direction. You’ll see the tradeoffs of each laid out plainly before anything gets ordered.
Usually, and the older your current unit the wider the gap. Trading a tired ten SEER system for modern SEER2 equipment tends to cut cooling costs noticeably. A variable-speed blower helps more here than it would up north, since it runs longer and pulls more humidity out along the way.
Manufacturer parts coverage on a matched system generally runs ten years once the equipment is registered, and we file that paperwork for you. Our labor coverage sits on top of it, and our satisfaction guarantee covers the workmanship. Ask and we’ll hand you those terms in writing.
