A Pueblo summer is a long test for an air conditioner

Pueblo sits on the Arkansas River at about 4,700 feet, and its summers are long and hot. The National Weather Service station at Pueblo Memorial Airport logged these numbers:

89 days	at 90°F or hotter in 2024, with a high of 106°F on July 12 and again on July 14.
70 days	at 90°F or hotter in 2025. The year topped out at 103°F — on five separate days between June 20 and August 7.
109°F	Pueblo’s all-time record, set July 13, 2003.
28 days	of 100°F or more in a single year — the record, reached in both 2003 and 2012.
1,078	cooling degree days in a normal year (1991–2020 normals).

What that means at your house: from late June through August, the outdoor unit can run most of the afternoon, every afternoon. A clogged filter, a weak capacitor or a slow leak that went unnoticed in May tends to announce itself during the first long run of upper-90s days. If your system is struggling early in the season, calling before the heat peaks is the easy way to stay ahead of it.

Before you call: four quick checks

These take five minutes and sometimes solve the problem outright. If they don’t, you’ve saved the technician a step.

Thermostat on Cool, set below room temperature. Fresh batteries if it has them. After you change a setting, give it about five minutes — most thermostats hold the compressor off for 3–5 minutes to protect it.
Breaker in the main panel. If the AC breaker has tripped, reset it once. If it trips again, leave it off and call — that’s an electrical fault, not a nuisance.
Outdoor disconnect. The small gray box on the wall beside the outdoor unit. Make sure it hasn’t been switched off or had its pull-out block removed. Many systems also have a switch near the indoor furnace or air handler.
Air filter. A filter packed with dust starves the system of airflow and can freeze the coil. If it’s gray and matted, replace it.

Hear a humming outdoor unit with a fan that won’t spin, or smell something burning? Skip the checks, turn the system off and call. More on that on our won’t-turn-on page.

When you call us

Tell us what’s happening. We’ll ask for your ZIP code, what kind of system you have — central air, swamp cooler, mini-split or heat pump — and what it’s doing.
We set the visit. You get the soonest window we can offer, around the clock when it can’t wait.
The technician diagnoses first. You hear what failed and what the fix involves before any work starts, and you decide.

The full walkthrough is here.

Cooling in Pueblo homes

Central air, swamp coolers and the houses that have both

Pueblo is dry enough for evaporative cooling to work well, so a lot of homes here still have a cooler on the roof — and plenty of house listings around town show evaporative cooling and central air in the same home. We work on all of it: split-system air conditioners, evaporative coolers, ductless mini-splits and heat pumps.

Older houses, older systems

The City of Pueblo puts the average home here at more than 55 years old, and about half of its single-family houses were built before 1980. In those homes the air conditioner often shares the job with older wiring, a ductwork layout that has been changed over the years, or an indoor coil sitting on top of a decades-old furnace. Our technicians look at the whole path — power, airflow, drainage, refrigerant — not just the part that failed.

When the power is the problem

Black Hills Energy supplies electricity in the city of Pueblo. Since 2025 it has had a Public Safety Power Shutoff program, cutting power to some areas during extreme wind and fire danger; in February 2026, about 90 customers in part of North Pueblo were without power for around four hours under one. If the whole house is dark, check for an outage before you call us. When power comes back, if the AC doesn’t start normally, that’s when we can help.

Is anyone at risk in the heat?

Someone feeling sick from the heat? Health first, AC second.

If anyone in the house is elderly, ill, very young, or showing signs of heat illness, don’t wait on a repair. Get them somewhere cool now: an air-conditioned home of family or friends, or an air-conditioned public building.

Call 911 for signs of heat stroke: a body temperature of 103°F or higher; hot, red, dry or damp skin; a fast, strong pulse; confusion; or passing out. While you wait, move the person somewhere cooler and cool them with wet cloths or a cool bath. Don’t give them anything to drink.

Heavy sweating, cold and clammy skin, a fast but weak pulse, nausea, cramps or dizziness point to heat exhaustion. Move to a cool place, loosen clothing and sip water, and get medical help if they vomit, get worse, or aren’t better within an hour.

Questions we hear

Do you really answer at night and on weekends?

Yes. The number is answered 24/7, including weekends and holidays. The hottest stretches in Pueblo don’t keep business hours, and neither do we. Call (719) 670-8043 and tell us what the system is doing; we’ll set up the soonest visit we can.

Do you cover Pueblo West?

Yes — Pueblo West (81007) and every Pueblo ZIP from 81001 through 81012. If you’re west of town, see our Pueblo West page for the few things that are different out there, like which electric co-op serves your side of Highway 50.

My AC is old and uses R-22. Can it still be repaired?

Often, yes. New R-22 hasn’t been produced or imported in the U.S. since January 1, 2020, but recovered and reclaimed R-22 can still legally be used to service existing systems, and nothing requires you to tear out a working unit. The catch is supply: it’s finite, so refrigerant repairs on these systems tend to cost more each year. If the repair involves a big leak or a compressor, we’ll talk through whether replacement makes more sense.

Should I keep running the AC if I see ice on it?

No. Switch cooling off at the thermostat and let the ice melt — running a frozen system can damage the compressor. Don’t chip at the ice. Our frozen coil page walks through what to do while it thaws.

How much will the repair cost?

It depends on what failed. A capacitor or contactor is a small part; a refrigerant leak, a fan motor or a compressor is a much bigger job, and the type of refrigerant in the system matters too. The technician diagnoses first and tells you what the fix involves before doing it. Our cost page explains what moves the price up or down.

Do you work on swamp coolers too?

Yes. Plenty of Pueblo houses still cool with a roof-mounted evaporative cooler, and some have one alongside central air. Pads, pumps, belts, motors, float valves and water lines are all part of the job. See swamp cooler repair.
