What AC Repairs Do We Handle?
Our Rockford HVAC team is fully equipped to repair any air conditioning issue, including:
Capacitor & Contactor Replacement: Failed capacitors are the most common AC problem we see in Rockford. When your capacitor fails, your air conditioner won't start or may hum without running. We replace worn capacitors and contactors quickly to restore cooling, typically within 1-2 hours.
Refrigerant Leaks & Recharge: Low refrigerant from leaks prevents your AC from cooling effectively. We use professional leak detection equipment to find even small leaks, repair them properly, and recharge your system with the correct refrigerant type, whether R-410A for newer systems or R-22 for older units.
Compressor Repair & Replacement: The compressor is your AC's heart. When it fails, your system won't cool at all. We diagnose compressor problems accurately and provide honest recommendations about repair versus replacement, since compressor replacement often costs $1,200-$2,500.
Fan Motor & Blower Service: Indoor blower motors and outdoor fan motors circulate air through your system. When they fail, you'll have weak or no airflow. We repair or replace failed motors to restore proper air circulation and cooling throughout your home.
Frozen Coil Repair: Ice forming on your indoor or outdoor coils indicates serious problems—low refrigerant, restricted airflow, or failed components. We identify the root cause, thaw your system safely, and fix the underlying issue to prevent re-freezing.
Thermostat Problems: From dead batteries to faulty wiring and calibration issues, thermostat problems prevent your AC from responding to temperature adjustments. We diagnose and repair all thermostat issues or install new smart thermostats if needed.
Condensate Drain Cleaning: Clogged condensate drains cause water leaks inside your home and can shut down your AC. We clear blocked drains, repair cracked pans, and ensure proper drainage to prevent water damage.
Common Signs You Need AC Repair
If you notice any of these warning signs, don't wait—call Gilley's for professional diagnosis and repair:
Weak Airflow from Vents: Weak airflow indicates blower motor problems, duct issues, or failing components that need immediate attention before complete failure.
Not Cooling Adequately: Your house staying 5-10°F warmer than the thermostat setting despite the AC running constantly shows your system isn't working properly.
Strange Noises: Grinding, screeching, or hissing sounds signal component failures—compressor bearings, fan motor issues, or refrigerant leaks requiring professional repair.
Frequent Cycling: Your AC turning on and off every 5-10 minutes instead of running steady 15-20 minute cycles indicates serious problems with your system.
Rising Energy Bills: Cooling costs increasing 20-30% without usage changes shows efficiency loss from failing components or refrigerant issues.
Ice Formation: Ice on your outdoor unit or indoor coils indicates refrigerant leaks or restricted airflow requiring immediate professional service.
Ignoring these warning signs can lead to complete system failure during the hottest days. Our technicians can inspect, diagnose, and fix the issue before it turns into an emergency.

Common Questions About AC Repair
-
Common causes include low refrigerant from leaks, dirty condenser coils restricting heat transfer, failed compressors unable to circulate refrigerant, frozen evaporator coils from airflow restrictions, or clogged air filters preventing proper air circulation. We diagnose the exact cause and provide appropriate repairs to restore cooling quickly. Don't wait until summer heat becomes unbearable—call for professional service at the first sign of cooling problems.
-
Your AC running constantly without cooling indicates serious problems like low refrigerant levels preventing proper heat transfer, oversized ductwork losing cool air, dirty outdoor coils unable to release heat effectively, failed compressors not circulating refrigerant, or undersized systems unable to handle Rockford's summer heat loads. We'll diagnose the root cause and recommend whether repair or replacement makes more sense for your situation.
-
During cooling season (May-September), we offer same-day service for 90% of calls received before 2pm. Emergency service is available 24/7 during peak summer months (June-August) when AC failures are most critical. Our average response time during emergencies is 2-4 hours, and we prioritize calls based on outdoor temperature and customer vulnerability.
-
Generally, repair your AC if it's under 10 years old and repair costs less than $600. Replace if it's 12+ years old, requires repairs exceeding $1,000, uses R-22 refrigerant (expensive and being phased out), or you've had 3+ repairs in 2 years. The 50% rule helps: if repair costs exceed 50% of replacement value AND your unit is over 10 years old, replacement offers better long-term value. We'll walk you through the cost-benefit analysis honestly.
-
AC systems freeze due to restricted airflow from dirty filters or failed blower motors, low refrigerant from leaks preventing proper heat absorption, blocked return vents restricting air circulation, or running the system when outdoor temperatures drop below 60°F. We identify the specific cause, thaw your system safely, fix the underlying problem, and prevent future freezing. Never ignore frozen coils—continuing to run a frozen AC causes expensive compressor damage.
-
Yes, our EPA-certified technicians are trained to repair all major AC brands including Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, American Standard, Amana, and more. We stock common parts for most brands and can order specialized components quickly when needed. Our experience with thousands of repairs means we understand the common failure points across all manufacturers.
-
Schedule professional AC maintenance annually before cooling season starts (typically April-May). Annual tune-ups catch small issues before they become expensive breakdowns during summer heat, maintain peak efficiency to keep operating costs low, extend equipment lifespan by 3-5 years, and keep manufacturer warranties valid. Many warranties require proof of annual professional maintenance. We offer Comfort Club memberships with automatic scheduling and priority service.
-
We accept all major credit cards, checks, and cash for your convenience. For larger repairs like compressor replacements, we can discuss payment plan options that fit your budget. Payment is due upon completion of the work unless other arrangements have been made in advance.
