Tucson homeowners call Temperature Control when an air conditioner stops cooling, a replacement is due, or a tune-up should happen before summer. Technicians diagnose first and explain the repair-or-replace choice before work starts, from Midtown to Casas Adobes. Heat pumps, furnaces, plumbing and electrical come from the same team. Call (520) 815-5665 or request service online.

Air Conditioning Repair

Our air conditioner technicians repair central air conditioners that blow warm air, short cycle, freeze up, leak water or will not start. Every repair begins with a diagnosis of refrigerant charge, airflow, electrical connections and the thermostat, and you hear what failed and what your options are before any work begins. Failed capacitors, contactors, fan motors, refrigerant leaks and clogged condensate drains are all part of the work, and the full list is on our air conditioning repair page.

Tucson homes run from mid-century bungalows in Sam Hughes to newer subdivisions around Rita Ranch. A repair call in either one works on the system that is actually installed, whatever its age, brand or ductwork, and we explain the problem in plain terms before recommending a fix.

Air Conditioner Replacement & Installation

When repairs stop making sense, we size a replacement from the home itself: a load calculation, a review of the existing ductwork, and equipment options laid out side by side. We remove the old system and install the new one, and financing is available for full system replacements. Details are on our air conditioning installation page. Tucson Electric Power’s 2026 Efficient Home Program lists early-retirement rebates of up to $600 for a central air conditioner and up to $720 for a heat pump. Amounts change with each program year, so we confirm current figures before you decide.

A multi-level home in the Catalina Foothills and a compact ranch near Reid Park call for different equipment sizing, so the plan starts with the house rather than the unit being removed. Whether you are replacing a system that failed or planning ahead before it does, we walk through the options for your home and your budget.

Emergency Air Conditioning Service

Our team is available 24/7 for emergency AC repairs, because a failed system in a Tucson summer is not a problem to leave for the next business day. When you call, tell us whether the system is blowing warm air, not starting or leaking water. That tells the technician where to begin, and the technician diagnoses the system and explains what failed before starting the repair. If the system is leaking or has iced over, shut it off at the thermostat while you wait.

We take emergency calls from the Tucson Mountains foothills on the west side to the neighborhoods around Tanque Verde on the east. A house without cooling in July gets uncomfortable quickly, and that is especially true for children, older adults and anyone with a medical condition, so we treat a no-cooling call as urgent.

AC Maintenance & Tune-Ups

A tune-up checks the parts that fail first: coils, refrigerant charge, electrical connections, the condensate drain and airflow. Our maintenance plans put that visit on the calendar so a worn part is replaced on an ordinary afternoon instead of the hottest one.

Scheduling before the first run of 100-degree days gives the system its checkup while it is still working. For a home in Fort Lowell or one near Davis-Monthan, that means the equipment has been looked at before the long cooling season, not after the first breakdown.

Heat Pumps & Heating Repair

Our heat pump technicians install, repair and maintain heat pumps that cool through the summer and heat through the winter, and our furnace technicians repair and replace gas furnaces. Heating matters less in Tucson than cooling, but a cold January morning still needs a system that starts, and we diagnose both the outdoor unit and the air handler or furnace inside.

Homes in Barrio Viejo and across the downtown core use a mix of equipment, from older gas furnaces to newer heat pumps. We work on the system you have and tell you plainly whether it is worth repairing or time to plan a replacement.

Ductless Systems, Zoning & Ductwork

Rooms without ducts, additions and homes with one stubborn hot room are where ductless systems and zone control systems earn their cost. We also repair, seal and clean ductwork through our air ducts service, since a leaking duct sends cooled air to the attic instead of the living room.

Some older homes in Armory Park and nearby neighborhoods predate central air, so ductless and zoning are worth asking about when existing ducts cannot reach a room. We look at the home and how you use it before suggesting a ducted or ductless route.

Plumbing, Electrical & Commercial Service

The same team also covers plumbing, including water heater repair and leak detection, and electrical work such as electrical panel upgrades. When a cooling problem traces back to a tripped breaker or a wiring fault, one company can fix both sides of it. Businesses get the same diagnosis-first approach from our commercial services team.

Whether the job is a home off Oracle Road or a shop on Speedway Boulevard, the call is the same: tell us what is happening, and we send the right technician for the trade.

Air Conditioning and HVAC Questions, Answered

Should I repair or replace an air conditioner that fails in a Tucson summer?

Repair a single failed component on a system that otherwise runs well. Replace when repairs keep stacking up, the unit is near the end of its life, or the house never gets comfortable even while it runs. Ask the technician for both options side by side so the numbers are on the table before you commit.

My AC stopped on a weekend night. What should I check before I call?

Confirm the thermostat is set to cool and has power, check that the breaker for the air handler and outdoor unit has not tripped, and replace a clogged filter. If none of that restores cooling, call us. Emergency AC repairs are available 24/7.

When is the right time for an AC tune-up in Tucson?

Late winter or early spring, before the system starts running most of the day. In Tucson that usually means February or March, ahead of the first stretch of 100-degree days. A tune-up checks the coils, refrigerant charge, electrical connections, condensate drain, filter and airflow, and a visit at that time leaves room to order a part if something is worn, rather than waiting on one in the middle of a July heat wave. If you missed that window, schedule it anyway, because a summer visit still catches a failing part before it stops the system. Our AC maintenance page covers what each visit includes, and the TEP rebate answer below lists the program amounts that apply to some tune-up work.

Which TEP Efficient Home rebates apply to AC service and replacement in Tucson?

TEP’s 2026 program listed $40 for coil cleaning and $80 for a refrigerant charge repair (once per unit), early-retirement rebates of up to $600 for central AC and $720 for a heat pump when the old compressor still runs for 15 minutes, and emergency-replacement rebates of up to $240 and $360. Amounts and rules change each year, so we check the current program with you first.

Is a heat pump worth considering in Tucson instead of AC plus a gas furnace?

Often, because one system cools through the long summer and heats through the short winter. Whether it fits depends on the home, the existing ductwork and whether gas service is already in place, so we look at the house before recommending either route.

I have an older home near the University of Arizona with no ducts. What are my options?

A ductless system cools room by room without opening walls, and a new duct system is possible when the structure allows it. A technician looks at the home, how you use it and what cooling it has now before suggesting one.
