Air Conditioning Repair
When your AC is running but your home is still warm, constantly cycling, making unusual noises, leaking water, or not turning on at all, the problem can come from several different components.
Our technician can inspect the complete cooling system, including the outdoor condenser, evaporator coil, refrigerant circuit, electrical components, thermostat, blower, capacitors, contactors, and condensate drainage system.
We service common AC problems including:
AC not cooling
AC blowing warm air
Air conditioner not turning on
Outdoor condenser not running
AC repeatedly turning on and off
Frozen evaporator coil
Weak airflow from vents
Refrigerant leaks
Water leaking around the furnace or air handler
Faulty capacitors and contactors
Thermostat problems
Unusual HVAC noises
High indoor humidity
Our goal is to determine why the system failed rather than simply replacing parts without proper diagnostics.
Heating & Furnace Repair
A dependable heating system is essential during an Illinois winter. Alan HVAC provides professional furnace and heating repair for residential and commercial customers.
We diagnose problems involving ignition systems, burners, flame sensors, inducer motors, blower motors, control boards, thermostats, pressure switches, safety controls, and other furnace components.

HVAC Maintenance & System Performance
Regular HVAC maintenance can help identify developing problems before they result in an unexpected breakdown.
During HVAC service, components can be inspected for wear, airflow restrictions, electrical problems, drainage issues, dirty coils, and other conditions that may affect heating and cooling performance.
Properly maintained equipment can operate more efficiently, provide more consistent indoor temperatures, and reduce unnecessary stress on major HVAC components.
HVAC System Replacement
Sometimes repairing an older heating or cooling system is no longer the most practical option.
If your equipment has a major failure, requires frequent repairs, uses outdated components, or has reached the end of its useful service life, we can discuss HVAC replacement options.
We can help evaluate the existing system and recommend an appropriate heating and cooling solution based on the property, existing ductwork, equipment configuration, and comfort requirements.

Frequently Asked Questions
Do you repair both air conditioning and heating systems?
Yes. Alan HVAC provides both AC repair and heating repair. We diagnose central air conditioning systems, furnaces, thermostats, blowers, condensers, evaporator coils, electrical components, and other HVAC equipment.
How much is an HVAC service call?
Our standard residential service call is $85. The service includes the technician’s visit and diagnostic evaluation. After diagnosing the system, we provide an estimate before completing the repair.
Is the service call applied toward the repair?
Yes. When you approve and proceed with the recommended repair through our company, the service call fee is applied toward the repair.
Why is my air conditioner running but not cooling?
Several problems can cause an AC system to run without properly cooling the home. Possible causes include restricted airflow, a dirty or frozen evaporator coil, electrical component failure, refrigerant problems, condenser issues, thermostat problems, or compressor-related faults. Proper diagnostics are necessary to determine the cause.
Why does my AC keep turning on and off?
Short cycling can be caused by electrical problems, thermostat issues, airflow restrictions, overheating, refrigerant conditions, safety controls, or other system faults. A technician should diagnose the system before parts are replaced.
Do you repair furnaces?
Yes. Furnace and heating repair remain an important part of our HVAC services. We diagnose ignition problems, burners, flame sensors, blower motors, control boards, pressure switches, thermostats, and other furnace components.
Do you repair refrigerant leaks?
Yes. We can diagnose HVAC cooling problems and inspect the system when a refrigerant leak is suspected. The appropriate repair depends on where the leak is located and the condition and age of the equipment.
Do you replace HVAC systems?
Yes. When an existing air conditioner or heating system is no longer economical to repair, we can discuss replacement options and recommend equipment appropriate for the property.
