Air Conditioning Contractor Las Cruces | Local Cooling Experts You Can Trust
Hi, I’m Gustavo—owner of A to Z Plumbing Heating and Cooling. If you live in Las Cruces, you know how brutal the summer heat can get. We’re not just talking about feeling warm—we’re talking 100+ degree days where your house turns into an oven if the AC so much as hiccups.
That’s why we take air conditioning seriously. My team and I have been keeping homes and businesses cool all across Las Cruces—from Mesilla and Northrise to Fairacres and Radium Springs. We don’t show up late. We don’t guess. We show up, fix it right, and leave you with cold air and peace of mind.
I’ve worked on old gas furnaces in Mesilla homes from the 50s and replaced broken blower motors in modern units out in Northrise. No matter what kind of setup you’ve got, we know how to keep the heat on.

Why Las Cruces AC Problems Aren’t Like Anywhere Else
Las Cruces heat hits different. We’ve got:
Long, dry summers that push AC systems to the limit
Dust storms that clog up outdoor units and filters
Hard water that wrecks condensate lines if not flushed properly
Older homes with poor insulation and undersized ACs
We’ve seen brand-new systems fail just because no one cleaned the coils or adjusted the charge for high heat loads. Our dry air, scorching temps, and sudden monsoons make Las Cruces a tough place for cooling systems.
That’s why it pays to hire a local contractor who knows the land—and the systems.

Las Cruces AC Systems Need More Than Just Cold Air
Most folks think air conditioning is just about blowing cold air—but here in Las Cruces, your system needs to handle:
High desert heat that pushes systems to their limit by mid-May
Dust and pollen that clog filters and coat coils fast
Monsoon moisture that can cause rust, corrosion, and short-circuits
Hard water issues that damage condensate drain lines
We’ve seen systems shut down just because the drain line got clogged with mineral buildup from Las Cruces water. That’s why we look at the whole system—not just the symptoms.
We Work on Every Type of System
Whether you’ve got a brand-new setup or something running since 1998, we’ve worked on it. We service:
Central air systems – split systems, package units, and gas/electric combos
Ductless mini-splits – ideal for garages, studios, or older homes
Heat pumps – efficient for year-round use in Las Cruces
Evaporative (swamp) coolers – common in older homes and add-ons
Multi-zone systems – for large homes with separate living spaces
Smart thermostats – we install and configure for real Las Cruces temps
No matter the system, if it cools air—we know how to fix, maintain, or replace it.
We keep it simple:
No hard sells
No upsell packages
No hidden fees
Just real heating service that works. Fast.

Warm air from vents when the system should be cooling
Unit runs constantly, but rooms stay hot
Weak airflow in one or more rooms
Bad smells or burning odors near vents
Strange noises—banging, buzzing, or rattling
Water leaks or puddles near the indoor unit
High electric bills with no change in usage
If you see any of these, it’s time to call a licensed air conditioning contractor—fast.
Uneven heating across rooms
Short cycling (turning on/off too often)
Sudden spike in your gas or electric bill

Want Lower Energy Bills? Let’s Talk Efficiency.
Upgrading to a newer, more efficient system can cut your cooling costs in half—especially if you’ve got a unit that’s 10+ years old. We help Las Cruces homeowners:
Choose the right SEER-rated unit for our climate
Size it properly for your home (not too small, not too big)
Install smart thermostats for better control
Balance your duct system for even cooling
We don’t just slap in a new unit—we make sure it works smarter for the way you live.
✅ What Las Cruces Homeowners Should Know About Their AC
We get a lot of questions from locals, so here’s what you should know if you want your air conditioning system to last—and run efficiently—in our unique climate.
1. Las Cruces Heat Load Is Tougher Than It Looks
Even though it’s a dry heat, homes in Las Cruces still need powerful AC systems. If your system was sized for another climate, it might be too small. Undersized units run constantly and break down faster. We always calculate for local heat load, not just square footage.
2. Filters Should Be Changed Monthly During Summer
Las Cruces is dusty. If you live near open desert (like in Vado or on the edge of Sonoma Ranch), your filters clog faster than most places. Changing your filter every 30 days can reduce energy use by up to 15% and extend the life of your blower motor.
3. Monsoon Season = Mold Risk
We’re dry most of the year—but during July and August, the humidity spikes. If your system isn’t draining properly, water can back up into the blower cabinet and grow mold fast. That’s why checking and clearing your AC drain line before monsoon season is so important.
4. Older Thermostats Waste Power
Still using a dial thermostat or basic digital one? Upgrading to a smart or programmable thermostat can save $100+ per year. Plus, it keeps your system from short-cycling when temps swing 20+ degrees in a day (very common here).
5. Duct Leaks Are Common in Las Cruces Homes
Many homes—especially in Northrise, Alameda-Depot, and older areas—have ducts that are leaking cool air into attics or crawlspaces. If your back rooms are hot, it might not be your AC unit—it could be poor ductwork wasting your cold air.
6. AC Tune-Ups Actually Save You Money
Most people skip annual maintenance. But here’s the deal: one dirty coil or a low refrigerant charge can spike your electric bill and wear out your compressor. A tune-up in May can cut your summer energy bill by 10–30% and prevent mid-season breakdowns.
7. Cooling an Add-On Room or Garage? Use a Ductless Mini-Split
If you’ve got a room addition, sunroom, or garage that stays hot, don’t oversize your main AC. Instead, a ductless mini-split is often the better move. It’s more efficient, doesn’t strain your existing system, and gives you control over just that space.

Frequently Asked Questions Las Cruces AC Customers Ask Us
How often should I service my AC in Las Cruces?
At least once a year—preferably in April or May, before the summer heat hits. In dusty areas like Fairacres or Vado, we recommend checking filters and coils more often. The dust here can shorten your system’s lifespan if ignored.
Why is one room in my house always hotter?
We see this a lot in homes around Sonoma Ranch and Las Colinas. Often it’s due to bad duct layout, leaks, or low airflow in longer duct runs. We offer airflow balancing and duct inspections to fix those hot spots.
Is it worth upgrading my AC in Las Cruces?
Yes—especially if your unit is 10+ years old. Newer systems are more efficient and better at handling high heat. With electric rates rising, an upgrade could cut your bill significantly during peak summer months.
Do you work on swamp coolers too?
We do! Some older homes in Alameda-Depot, Doña Ana, and downtown Las Cruces still use evaporative coolers. We can service, clean, or help you upgrade to refrigerated air if you’re ready.
Can you install AC in homes without existing ductwork?
Yes—ductless mini-splits are perfect for older homes in Mesilla Park, casitas, or garage conversions. They’re quiet, energy-efficient, and don’t need full duct systems.
Do you offer emergency AC repair in Las Cruces?
Absolutely. During July and August, we get flooded with urgent calls. We keep slots open for same-day or next-day service, especially for families and elderly customers in the heat.
