Is Your AC Showing These Symptoms? We Have the Solution.
Air conditioning systems often give warning signs before a complete breakdown. Recognizing these common problems can help you act quickly and prevent more extensive damage. We specialize in resolving a wide range of AC issues common in O'Fallon homes and businesses.
AC Blowing Warm Air or Not Cooling
This is a common and frustrating issue. Causes can range from low refrigerant levels due to a leak, a dirty condenser coil, a faulty compressor, or issues with the fan motor. Our repair approach involves leak detection, refrigerant recharge (if applicable), thorough cleaning, or component repair/replacement.
AC Making Strange Noises
Unusual sounds like grinding, squealing, banging, or hissing can indicate various problems. Grinding might signal a failing motor bearing, squealing could be a worn belt, and banging often points to a loose or broken part. We accurately pinpoint the source of the noise and make the necessary adjustments or replacements.
Frozen Evaporator Coils
If you notice ice on your indoor unit's coils, it usually points to a lack of airflow or low refrigerant. Causes include a clogged air filter, blocked return air vents, a malfunctioning blower motor, or a refrigerant leak. We address the root cause, whether it's airflow restriction or refrigerant management.
Water Leaks Around Your AC Unit
Water pooling around your indoor unit is a sign of trouble, often a clogged condensate drain line or a frozen evaporator coil that's now melting. Our service includes clearing blockages, inspecting the drain pan, and addressing any issues leading to the leak.
AC Cycling On & Off Frequently
Known as "short cycling," this can be due to an oversized unit, a faulty thermostat, a dirty air filter, or refrigerant issues. Frequent cycling not only reduces comfort but also increases energy consumption and system wear. We diagnose the specific cause and calibrate or repair as needed.
AC Not Turning On At All
This could be a simple tripped circuit breaker, a faulty thermostat, or a more serious electrical issue within the unit or its components. Our technicians meticulously check the electrical system, from the thermostat to the outdoor unit, to restore power and operation.

Our expertise covers all critical components of your air conditioning system:

Navigating Your Options: AC Repair vs. Replacement
A common question for homeowners in O'Fallon is whether to repair their existing AC or invest in a new system. This decision depends on several factors, and we provide honest, unbiased advice to help you make the best choice for your situation.
Consider the "5,000 Rule": Multiply the age of your unit by the estimated cost of the repair. If the total exceeds $5,000, replacing the unit might be the more cost-effective long-term solution. Other factors include:
- Age of Unit: Systems older than 10-15 years are generally less efficient and more prone to breakdowns.
- Frequency of Repairs: If your unit requires frequent, costly repairs, replacement might save you money in the long run.
- Current Repair Cost: Is the cost of the repair a significant percentage of a new system's price?
- Energy Efficiency: Newer AC systems are significantly more energy-efficient, offering substantial savings on utility bills.
- Comfort Needs: If your current system struggles to maintain consistent comfort, an upgrade could be beneficial.
Our technicians will provide a comprehensive assessment, detailing both repair options and the benefits of a new installation, allowing you to make an informed decision based on your budget and needs.
