Warning Signs
When to Call for AC Repair
In St. George and across Southern Utah, your air conditioner works harder than almost anywhere else in the country. When summer temperatures regularly exceed 110 degrees, even minor AC issues can quickly escalate into major problems — or even a complete system failure. Recognizing the early warning signs of a struggling AC system can save you from an uncomfortable and potentially dangerous situation.
Warm or inconsistent airflow is one of the most common signs that something is wrong. If your vents are blowing lukewarm air or some rooms are significantly warmer than others, your system may have a refrigerant leak, a failing compressor, or a problem with your ductwork. In our desert climate, even a small drop in cooling performance is immediately noticeable.
Unusual noises such as grinding, squealing, banging, or rattling should never be ignored. These sounds often indicate loose or worn components, a failing motor bearing, or debris caught in the blower assembly. What starts as a minor noise can quickly become a major mechanical failure if left unaddressed.
Rising energy bills without a corresponding increase in usage are a telltale sign that your AC is losing efficiency. When components wear down or refrigerant levels drop, your system has to work harder and run longer to maintain the same temperature, driving up your electricity costs significantly.
Frequent cycling — your AC turning on and off repeatedly in short intervals — puts enormous stress on the compressor and other components. This short-cycling behavior can be caused by an oversized system, a faulty thermostat, low refrigerant, or electrical problems. Left unrepaired, it dramatically shortens the lifespan of your equipment.
Moisture or leaking around your indoor unit can indicate a clogged condensate drain, a frozen evaporator coil, or even a refrigerant leak. Any moisture issue should be addressed promptly to prevent water damage, mold growth, and further system damage.

Common AC Problems We Fix
Our technicians have seen and repaired thousands of AC issues. Here are the most common problems we encounter in Southern Utah homes.
Refrigerant Leaks
Low refrigerant is one of the most common causes of poor cooling performance. Leaks can develop in the evaporator coil, condenser coil, or refrigerant lines over time. We locate the leak, repair it, and recharge your system to manufacturer specifications. Running a system with low refrigerant causes the compressor to overheat and can lead to complete compressor failure, which is a far more expensive repair.
Frozen Evaporator Coils
When airflow is restricted or refrigerant levels are low, the evaporator coil can freeze over, causing your AC to blow warm air or stop working entirely. Common causes include dirty air filters, blocked return vents, a failing blower motor, or refrigerant issues. We identify the underlying cause, thaw the coil safely, and make the necessary repairs to prevent it from happening again.
Clogged Filters & Airflow
The fine desert dust in St. George clogs air filters much faster than in other climates. A severely clogged filter restricts airflow, forcing your system to work harder and potentially causing the evaporator coil to freeze. We replace your filter, check your ductwork for obstructions, and ensure proper airflow throughout your home for maximum comfort and efficiency.
Electrical Failures
Capacitors, contactors, relays, and wiring connections can all fail due to the extreme heat and constant operation that St. George summers demand. Electrical issues can cause your system to stop running entirely, trip breakers, or operate intermittently. Our technicians carry common electrical components on their trucks so most repairs can be completed in a single visit.
Thermostat Malfunctions
A faulty thermostat can cause your AC to cycle improperly, fail to reach the set temperature, or not turn on at all. We diagnose whether the issue is with the thermostat itself, the wiring, or the connection to your system. If a replacement is needed, we can install and program a new smart or programmable thermostat for optimal comfort and efficiency.
Compressor Issues
The compressor is the heart of your AC system, and when it fails, your entire system stops cooling. Compressor problems can result from electrical issues, refrigerant problems, or simply years of hard use in our extreme climate. We diagnose compressor issues accurately and advise you honestly on whether a repair or a system replacement is the best investment for your situation.
