Air Conditioning Repair Services We Provide

Our technicians repair the problems that leave a Tucson home too warm, from a system that will not start to one that runs all day and never catches up:

• No cooling or warm air from the vents: finding the cause of a system that runs without cooling the house
• Capacitor, contactor, and relay failures: replacing the electrical parts that start the compressor and fan
• Fan motor repair: fixing condenser and indoor blower motors that are noisy, slow, or stalled
• Refrigerant leaks: locating the leak, repairing it, and restoring the system's charge
• Frozen evaporator coils: clearing the ice and correcting what caused it
• Clogged condensate drains: stopping water leaks and drain-pan overflow
• Thermostat and control problems: repairing or replacing a thermostat that misreads or ignores the system
• Short cycling: diagnosing a system that shuts off soon after it starts
• Heat pump repair: servicing heat pumps that cool the home through the summer

24/7 Emergency AC Repair

If your cooling quits at night, on a weekend, or on a holiday, call us. We answer emergency repair calls around the clock, and the technician who arrives diagnoses the system, explains what failed, and gives you a free pricing quote before starting the repair. If your system is leaking water or has iced over, shut it off at the thermostat while you wait so the problem does not grow.

When summer highs in Tucson pass 100 degrees, a house without cooling gets uncomfortable fast. From a home near Sam Hughes to one on the far southeast side by Rita Ranch, we treat a no-cooling call as urgent, especially when children, older adults, or anyone with a medical condition is inside.

AC Blowing Warm Air or Not Cooling

A system that runs but blows warm air usually points to an airflow, refrigerant, or electrical problem. Our technicians check the thermostat settings, filter, and coils first, then test the capacitor, contactor, fan motors, and refrigerant charge to find the failing part. You get a clear explanation of what failed and what the repair involves before work begins. Our guide to why an air conditioner blows warm air walks through the common causes.

If your air conditioner cools in the morning but loses ground in the afternoon, when it works hardest, call before it fails completely.

AC Short Cycling, Strange Noises, and Uneven Cooling

An AC that shuts off minutes after it starts, rattles, squeals, or leaves one room hotter than the rest is telling you something is wrong. Short cycling can come from a failing component, a frozen coil, or restricted airflow, while a new grinding or squealing sound often points to a motor or bearing. Catching these early can keep a small repair from becoming a system replacement, and routine AC maintenance is one way to spot worn parts before they fail. Our guides explain why an AC keeps turning on and off and why an AC makes loud noises.

Hot and cold spots across the house can also point to airflow trouble, so we look at the system and the air it delivers. Whether the home is in Catalina Foothills or on the northwest side, a room that will not cool is worth a closer look at the ducts as well as the equipment.

Heat Pump Repair

A heat pump cools the home in summer using the same refrigerant cycle as a central air conditioner and can fail in many of the same ways. We repair heat pumps for weak cooling, frozen coils, failed capacitors, noisy fans, and control problems, and we diagnose both the outdoor unit and the air handler inside.

If your heat pump struggles to cool in summer, getting it checked now means it is ready when the weather turns cold. Our heat pump repair team handles the repair, and you can ask about our maintenance plan for regular checkups.

AC Repair or Replacement

Repair is usually the right call for a newer system with one failed part. Replacement starts to make sense when the system is old, breaks down repeatedly, uses an older refrigerant, or needs a repair that costs a large share of a new unit. We tell you which applies to your system and what each path involves, so you can decide with the facts in front of you.

If replacement is the better value, our AC installation team can quote a new system, and you can ask about financing, subject to approved credit. If a repair will carry you through, we fix it and tell you what to watch for.

AC Repair Questions Answered Before You Call

Is it normal for my AC to run all day during a Tucson heat wave?

On the hottest afternoons, a system that runs for long stretches can be working as designed, especially if it still holds the temperature you set. It is a warning sign when the house keeps warming despite constant running, airflow from the vents weakens, ice forms on the indoor unit, or the outdoor unit shuts off soon after it starts. Any of those points to a failing part or a refrigerant problem, and it is worth a call before the next heat wave makes it worse. Our technicians can tell a system doing its job from one that is falling behind.

Does TEP offer a rebate for AC refrigerant repair or coil cleaning?

For TEP customers, yes. The 2026 Efficient Home Program lists $80 for a refrigerant charge repair, which applies once per unit, and $40 each for indoor and outdoor coil cleaning. We are a TEP participating contractor and provide the itemized invoice you need to apply. Amounts and eligibility change from year to year, so confirm current terms with TEP or when you call. Our 2026 TEP Efficient Home Program guide lists the details.

If my AC dies completely, can I still get a TEP rebate on a replacement?

Yes, but a system that no longer runs qualifies for a smaller rebate. The 2026 program lists up to $240 for a central air conditioner and up to $360 for a heat pump when the old unit is not operational. A system that still runs can qualify for an early-retirement rebate of up to $600 for central AC or $720 for a heat pump, if its compressor runs for 15 minutes and it meets the program's efficiency limit. The new equipment must meet TEP's requirements, so if your system is struggling, ask us about the program before it fails completely. The TEP rebate breakdown shows how each amount is calculated.

Can a monsoon storm or power surge damage my Tucson AC?

It can. Storms and utility switching can cause power surges, and a surge can trip a breaker or damage electrical parts such as the capacitor or control board. After an outage, wait a few minutes before restarting the system, and if it will not start, check that its breaker has not tripped before you call us. A whole-home surge protector installed at the panel can reduce the risk, and our electricians install them. Our guide to protecting your home during monsoon season has more.

My Tucson home has a heat pump instead of a central AC. Does that change the repair?

The cooling side is repaired much like a central air conditioner, but a heat pump has extra parts, including a reversing valve and defrost controls, because it also heats the home in cooler weather. We repair the outdoor unit, the indoor air handler, and those controls.
