Furnace Repair Service Las Cruces — Honest Heat When You Need It Most

Hey, I’m Gustavo — owner of A to Z Plumbing Heating and Cooling, right here in Las Cruces. I’ve been fixing furnaces around this city for over 15 years. From freezing mornings in Mesilla to busted blowers in Doña Ana, I’ve seen what happens when a furnace quits working — and how fast things can go from chilly to stressful.

One time we got a call from a family over near Alameda-Depot. Their furnace had died in the middle of the night. It was 29 degrees outside. They had two little kids and a dog wrapped in blankets. We got there by 9 AM, swapped out a bad ignitor, and had the heat back before lunch.

That’s what we do. Real repairs. No drama. Just solid work to keep your home or business warm.

Why Furnace Repairs Matter in Las Cruces

Most people think Las Cruces is always hot. But those of us who live here know better.

Winter mornings hit hard. Temps can drop into the 20s. And in older homes — like the ones you find in Mesilla Park, Alameda-Depot, and even parts of Sonoma Ranch — poor insulation makes it worse. Your furnace has to work overtime just to keep up.

We’ve seen systems shut down from:

  • Dust and dirt in the burners

  • Cracked heat exchangers

  • Bad flame sensors

  • Blower motors that grind to a stop

  • Thermostats that misfire

And in newer homes? It’s often cheap parts, bad ductwork, or oversized units running wrong.

What Furnace Repair Service Includes

Here’s what we usually check and fix when you call us:

  • Thermostat problems

  • Blower motor issues

  • Flame sensor and ignitor replacement

  • Gas valve checks

  • Electrical troubleshooting

  • Pilot light issues

  • Clogged filters

  • Noisy or vibrating units

  • Heat exchanger safety inspection

  • Airflow and pressure readings

We work on all types — gas, electric, and combo units. And yes, we fix both home and commercial furnaces.

What It’s Like When We Show Up

We keep it simple:

  1. We show up when we say we will

  2. We look at the system — no guessing

  3. We explain what’s wrong in plain words

  6. You stay warm

Real Work Across Real Neighborhoods

We’ve worked everywhere — old ranch homes in Mesilla, newer townhomes in Northrise, businesses near University Ave, and even an office that used to be a house in Fairacres.

A guy called us last January from Las Alturas — his furnace ran nonstop and never hit the target temp. We found his ductwork leaking into the attic. Sealed it. Rerouted a couple of vents. Problem solved.

Quick Fix in Mesilla Park

We had a couple in Mesilla Park call us after waking up to 55° inside. Their furnace was running, but no heat. Turned out the filter was so clogged it choked the airflow. We swapped it out, cleaned the blower, and had the heat back in 30 minutes. Simple fix — but they’d been freezing for days.

Furnace Trouble at a Small Business in Mesilla

We once helped a little bakery off Avenida de Mesilla. Their heater quit right before a weekend rush. Their dough wouldn’t rise, and customers were bundled in coats. We found a failed control board and had it replaced the same day. They didn’t lose a single hour of service. That’s the kind of work we’re proud of.

Common Furnace Problems We See Around Las Cruces

Some issues are more common in certain areas:

  • Dust buildup is worse in homes near open fields, like Vado and Fairacres

  • Old ignitors fail often in houses built before 2000, especially in Mesilla Park

  • Oversized units are common in new builds around Sonoma Ranch — they short-cycle and waste energy

  • Improper duct design in remodeled homes near University Park leads to cold spots and airflow issues

Knowing how homes are built in Las Cruces helps us find and fix problems faster.

Do Businesses Need Furnace Repair?

Absolutely. We’ve worked on:

  • Office buildings near Downtown Las Cruces

  • Auto repair shops on Valley Drive

  • Restaurants near University Ave

  • Medical clinics in Las Alturas

If it heats up a space, we can fix it — fast, clean, and without slowing down your day.

Furnace Repair vs Replacement — What We Think

Some companies will push you to replace your furnace right away. We don’t.

Here’s how we break it down:

  • If the unit is under 15 years old, a repair is usually the better option

  • If the heat exchanger is cracked or repairs cost over 50% of a new unit, we’ll talk about replacement — not before

We give our honest take, every time. We don’t sell what you don’t need.

Keep Your Furnace Healthy

Here are a few quick ways to keep your system running right all winter:

  • Keep your thermostat batteries fresh — it solves half the “my heat won’t turn on” calls

  • Make sure your outside vents aren’t blocked by leaves, dust, or animals

  • Don’t shut too many vents — it throws off pressure and makes your furnace work harder

  • Always call for help if you smell burning plastic or gas

We keep it simple:

  • No hard sells

  • No upsell packages

  • No hidden fees

Just real heating service that works. Fast.

Emergency Call in Tortugas

Last winter, we got a call from a family in Tortugas just after midnight. Their furnace stopped working, and the home was dropping below 50 degrees inside. We were on-site before sunrise, found a shorted limit switch, and had the system running before breakfast. They were surprised we even answered the phone — we just call that doing the job right.

Messy Repair Follow-Up in University Park

A customer in University Park reached out after another company installed a new gas furnace but left behind a mess — parts on the ground, wires barely taped, and no airflow to two of the bedrooms. We fixed the install, cleaned up the mess, and balanced the ductwork. That homeowner now recommends us to everyone on their block.

Heating Fix for a Rental in Vado

We’ve done a lot of work on rentals in Vado, especially older duplexes with wall furnaces or combo units. One unit wouldn’t start, and the tenant had been using space heaters for a week. We found a stuck gas valve and got it replaced same day — heat was restored, and the landlord finally had a vendor they could trust.

Heater Issues at a Shop Near Valley Drive

There’s a small detailing shop off Valley Drive that kept losing heat overnight — the furnace would shut off around 2 a.m. and not restart until morning. Turns out the thermostat was wired through a faulty breaker. We re-ran the connection, replaced the board, and that shop’s been warm ever since.

Furnace Tune-Up Blitz in Sonoma Ranch

Before the first cold snap last fall, we did back-to-back furnace checkups in Sonoma Ranch — five homes in one day. Every system had some sort of issue: dirty filters, weak ignitors, loose wires, or airflow problems. No breakdowns were reported that winter. That’s the kind of proactive work that makes a difference.

Furnace Noise Call in Fairacres

We had a homeowner in Fairacres call about a loud banging noise every time their furnace kicked on. Turns out the ductwork was expanding too fast from heat buildup — the blower speed was set too high, and the return was undersized. We reprogrammed the board, adjusted the flow, and added a return grill. No more noise, and the home heats up more evenly now.
