When your AC fails in Arizona's summer heat, Precise Air & Heating provides 24/7 emergency AC repair in Gilbert, Mesa, Chandler, Queen Creek, San Tan Valley and the Greater Phoenix Metro.
NATE-certified technicians diagnose the HVAC issue, verify any manufacturer part warranties and provide upfront pricing on repairs

Hot air blowing from vents, unexpected shutdowns, or an AC that won't turn on can have different underlying causes.
Our technicians use advanced HVAC diagnostic tools and technology to test electrical components, motors, safety controls, airflow, and refrigerant system operation as needed.
Our approach is repair first not upselling to replace equipment or components without a verified reason and solutions. We rely on actual test results to identify the problem and recommend the appropriate repair.
Fully Stocked Service Vehicles Prepared to Restore Your Cooling
Our service vehicles carry a wide selection of commonly needed AC repair parts, including compatible universal replacement components, helping us complete most repairs during the initial visit.
When a manufacturer-specific part isn't available, we evaluate whether a safe, compatible temporary repair can restore cooling while waiting for the correct part. Not every failure allows a temporary solution, and we never compromise equipment safety to get a system running.
Once an approved repair is completed, we verify proper system operation and cooling performance.
During Arizona's extreme summer heat, an air conditioner can continue running even when cooling has failed. Not every AC problem requires after-hours service, but certain warning signs can indicate an urgent cooling failure, electrical hazard, or risk of additional equipment damage.
AC Running but Blowing Warm Air
If your AC runs continuously but blows warm or room temperature air, the outdoor cooling system may not be operating properly. Possible causes include a failed capacitor, condenser fan motor, compressor, or refrigerant related problems. If indoor temperatures continue rising, emergency service may be necessary.
Air Conditioner Won't Turn On
A failed electrical component, thermostat, control board, or condensate safety switch can prevent your AC from starting. If the circuit breaker repeatedly trips, leave the system off. Repeatedly resetting the breaker can create a safety hazard or cause additional equipment damage.
Burning Smells, Smoke, or Electrical Problems
Burning electrical odors, visible sparking, or smoke may indicate overheating wiring, damaged electrical components, or a serious electrical failure. Turn off the system if it's safe to do so. If smoke or fire is present, evacuate the area and call 911.
Loud Grinding, Screeching, or Banging
Unusual mechanical noises can indicate failing motor bearings, damaged fan components, or compressor problems. Continuing to operate the equipment could cause further damage. Shut the system off and arrange professional service.
Frozen Evaporator Coil or Water Leaking
Ice on refrigerant lines or the indoor evaporator coil may indicate restricted airflow, blower problems, or a refrigerant-system issue. Water around the indoor unit may result from a clogged condensate drain, overflowing drain pan, or melting ice. Turn cooling off, avoid contact with wet electrical equipment, and never attempt to chip away ice or bypass safety switches.
AC Struggling to Maintain Temperature During Extreme Heat
When outdoor temperatures exceed 110°F, air conditioners may run longer to maintain indoor comfort. However, a steadily rising indoor temperature, significantly reduced cooling, or a system that repeatedly shuts down may indicate a problem requiring service.
If indoor heat becomes unsafe, especially for infants, older adults, or anyone sensitive to high temperatures, move to a cooler location while arranging assistance.
Need Emergency AC Repair?
If you're experiencing any of these warning signs, call (602) 396-0869 to discuss your cooling problem and confirm the earliest available emergency appointment.
Once your emergency AC service appointment is confirmed, a few simple preparations can help your technician identify the problem efficiently.
Avoid opening electrical panels, handling refrigerant components, or attempting repairs yourself.
1. Check Your Thermostat Settings
If there are no signs of electrical or mechanical hazards, verify that your thermostat is set to COOL, the temperature is set below the current room temperature, and the fan is set to AUTO. Note any error codes or unusual thermostat messages.
2. Inspect Your Air Filter & Vents
A severely dirty air filter or blocked return grille can restrict airflow and contribute to cooling problems. Check accessible filters and make sure supply and return vents aren't obstructed. Don't restart equipment that was shut off because of a safety concern and may reset prior error codes.
3. Document What Happened Before the Breakdown
Note when the cooling problem started, whether the outdoor unit was operating, and any unusual noises, odors, or thermostat alerts. Photos of error messages, visible ice, or water leaks can provide helpful information, even if those symptoms disappear before the technician arrives.
4. Make Your HVAC Equipment Accessible
Clear a safe path to the thermostat, indoor air handler, and outdoor condenser. If equipment is located behind a locked gate or inside a utility closet, arrange access before the appointment. Secure all pets so the technician can work safely.
5. Reduce Indoor Heat While Waiting
Close blinds and curtains exposed to direct sunlight and avoid using ovens or other appliances that add unnecessary heat. Monitor indoor temperatures, especially when children, older adults, or heat sensitive individuals are present.
If your home becomes dangerously hot, seek an air-conditioned location rather than waiting inside. Arizona's official Heat Resource Hub provides information on cooling centers and heat-relief resources.
The emergency diagnostic charge and the cost of repairing your air conditioner are two separate things. We confirm the service charge before dispatch and provide the actual repair price once the cause of the failure has been properly identified.
24/7 Emergency Diagnostic Trip Charge: $189–$289
Our emergency diagnostic trip charge ranges from $189 to $289, depending on current service demand and technician's' availability. This includes after-hours, weekends, and holiday emergency service. The applicable charge is confirmed before a technician is dispatched.
What's Included in the Emergency Diagnostic Charge?
The charge covers the service visit and professional evaluation required to determine why your air conditioner isn't working. Replacement parts, refrigerant, and repair labor are separate from the diagnostic charge. Any recommended repairs are quoted for your approval before work begins.
What Determines the Final Emergency AC Repair Cost?
Repair costs vary because not every cooling failure requires the same parts, labor, or amount of work. Replacing a failed electrical component is different from repairing a refrigerant leak, diagnosing a compressor failure, or accessing equipment in a difficult attic or rooftop location.
The final price depends on the confirmed failure, equipment type, required parts and their availability, system accessibility, labor involved, and any refrigerant or leak-related work. Some repairs can be completed during the initial visit, while others may require manufacturer-specific parts.
Will I Know the Total Repair Cost Before Approving the Work?
Yes. After identifying the problem, your technician explains the recommended repair and provides the price before any work is performed. You'll know what needs to be repaired and what it will cost before deciding whether to proceed.
No repairs or parts replacements are performed without your authorization.
Can I Schedule Service During Normal Business Hours Instead?
Absolutely. If your cooling problem isn't urgent and it's safe to wait, scheduling during normal business hours can reduce your diagnostic expense.
Our standard AC diagnostic is $89.95, and that charge is applied toward an approved repair completed during the same visit.
For nonemergency cooling problems, visit our AC Repair service page to learn more about standard diagnostics and scheduling.

An AC breakdown does not automatically mean you need a new system. We consider the failure, equipment condition, repair history, refrigerant type, and remaining warranty coverage.
One failed component in an otherwise sound system
A capacitor, contactor, control, or motor repair may be practical when the rest of the equipment is in good condition. We explain whether the failure appears isolated or connected to another problem.
An expensive compressor or coil repair
Compare the full repair price with a replacement estimate. Manufacturer parts coverage can affect the comparison, but labor, refrigerant, and the condition of the remaining components also matter.
Repeated breakdowns or several deteriorating components
A repair may restore operation without resolving other developing problems. We explain what the proposed work addresses and what concerns would remain.
Poor comfort before the breakdown
Hot rooms and weak airflow can involve ductwork, equipment setup, or other home conditions. A new air conditioner alone may not correct those issues.
Repair costs approaching a substantial share of replacement
Review both options before committing. Age or a price percentage alone should not make the decision for you. We help you compare the scope, warranty protection, and limitations of each option.
If replacing your AC is the better investment, we provide a free replacement estimate detailing the recommended equipment, installation scope, and total price.
We do a full heat load calculation to properly size your HVAC system and evaluate whether your airflow and ductwork need any modification's. Financing options are available, subject to credit approval.
Your new system includes a 10-year manufacturer parts warranty, subject to manufacturer terms and registration requirements, plus our 5-year workmanship warranty on the installation.

Answers about troubleshooting, after hour Ac repairs refrigerant, warranty coverage, and keeping your home comfortable during Arizona’s cooling season.
Set the thermostat to Cool with the temperature below the current room temperature. Check an accessible air filter and make sure supply vents and return grilles are unobstructed.
Note whether the indoor blower and outdoor unit run, and whether you see ice or water. Share those observations when scheduling. Do not remove electrical covers, bypass safety switches, or repeatedly reset a breaker that trips.
Hearing the indoor fan does not confirm that the outdoor unit or compressor is operating. If the thermostat fan is set to On, it can also circulate room-temperature air between cooling cycles.
If the system is calling for cooling but the house remains warm, we check airflow, indoor and outdoor equipment operation, and refrigerant performance. Warm air alone does not prove you need refrigerant or a new compressor.
No. An air conditioner circulates refrigerant through a closed system and does not normally consume it. A low charge may result from a leak or an incorrect charge from previous work.
We evaluate the system before recommending refrigerant. If leak testing is needed, we explain the method and cost. Adding refrigerant does not repair a leak, and repeated top-offs can leave the underlying problem unresolved.
A first-visit repair depends on the confirmed failure, the correct part being on hand, and the work required. Some repairs can proceed after you approve the price; model-specific motors, boards, coils, or compressors may require ordering. We offer same-day AC service, but some repairs require another visit. Your technician explains the next steps and expected timing before you commit to the work.
A manufacturer parts warranty is different from labor coverage. It may cover an eligible replacement part while leaving diagnosis, labor, refrigerant, shipping, or other charges your responsibility.
Coverage depends on the warranty terms, registration, equipment age, and failure involved. We check applicable coverage and explain what is covered and what you would pay before requesting approval.
Long cooling cycles can be normal in extreme heat. Variable-capacity equipment may also run for extended periods at lower output.
Consider whether the system maintains the thermostat setting and whether performance has changed. Rising indoor temperatures, noticeably weaker airflow, ice, or a sudden loss of cooling deserve investigation. Runtime alone does not tell you whether the equipment is failing or incorrectly sized.
Yes. A heat pump provides air conditioning as well as heating. We diagnose cooling problems involving the compressor, fans, electrical components, controls, refrigerant circuit, and reversing valve.
Tell us whether the problem occurs in cooling, heating, or both. That information helps guide testing. We also service central air conditioners, packaged rooftop units, air handlers, and ductless mini-splits.
Yes. Call (602) 396-0869 for 24/7 emergency AC service and current scheduling information.
The diagnostic fee for after-hours, weekend, and holiday visits ranges from $189–$289, depending on call demand and technician availability. We confirm the diagnostic fee before scheduling. Repair work is quoted separately after diagnosis.
Tell us when the problem started, whether the system still runs, and which areas of your home are affected. We will help you arrange the next step.
