A weak cooling system often points to low refrigerant from a leak, dirty coils or filters restricting airflow, or a failing compressor. Our HVAC technicians will inspect the unit, locate and repair any leaks, recharge the system to proper levels, clean or replace filters and coils, and determine whether the compressor or electrical controls need attention. Prompt professional AC repair ensures your cooling system returns to peak performance and prevents further damage.

Rattling, grinding or screeching sounds usually indicate loose screws, worn fan bearings or lack of lubrication in the compressor. Other noises like whistling or banging can come from air leaks in ductwork or failing motors and should be checked immediately. Continuing to run a noisy unit risks costly damage – our cooling repair specialists diagnose the issue, tighten components, lubricate moving parts and replace damaged motors or compressors as needed.

We consider the system’s age, repair history, and efficiency before recommending repair or replacement. If your air conditioner is more than ten years old or the cost of repairs multiplied by the unit’s age exceeds about $5,000, replacement with a newer high‑efficiency model may be smarter. For newer systems (under five years) or minor issues, a professional AC repair can extend the unit’s life and save on upfront costs. Thinking about a new system? See our AC replacement page.

It’s best to schedule a professional tune‑up at least once a year – ideally in the spring before peak cooling season to clean coils and filters, check refrigerant levels and electrical controls, and verify safe operation. Regular maintenance improves energy efficiency, catches small issues early and helps your air conditioner last 10-15 years. Our HVAC maintenance plans make it easy to keep your AC running smoothly and avoid unexpected cooling repairs.

Water leaks often come from a clogged condensate drain line or a frozen evaporator coil. Turn off the unit to prevent damage and call a professional to diagnose and fix the issue.

Short cycling can indicate an oversized system, a dirty air filter or a malfunctioning thermostat. Frequent starts and stops reduce efficiency and can shorten the life of your equipment, so have a technician evaluate the system.

Use high‑quality air filters, schedule regular maintenance and consider adding a whole‑home air purification or filtration system. Cleaning ducts and maintaining proper humidity levels also help.

Keep filters clean, close unused vents, seal duct leaks and set your thermostat at an efficient temperature. Annual tune-ups keep the coil and blower clean so the system uses less energy, and energy-efficient upgrades like a smart thermostat or a higher-efficiency unit can lower your bills further. We can check your system and suggest what will help most.

Check that the thermostat is set to COOL and below room temperature, and replace its batteries. Then check the breaker and the outdoor disconnect switch. A full condensate pan or a clogged drain can also trip a float switch that shuts the system off. If none of those is the problem, a failed capacitor, contactor or control board is a common cause.

Ice usually means the system doesn’t have enough airflow, from a dirty filter, closed vents or a failing blower, or that it’s low on refrigerant, which means there’s a leak. Turn the cooling off and run the fan only to thaw it, and change the filter. If the ice comes back, call us, because running a frozen system can damage the compressor.

It depends on what failed (a capacitor, a fan motor, a refrigerant leak or the compressor), the age and brand of the system, the availability of parts, and how long diagnosis takes. Older systems that use R-22 refrigerant can cost more to recharge. We diagnose first and give you an upfront quote before any work. Call 312-500-4822.

Many common repairs, like capacitors, contactors, fan motors and clearing a clogged drain line, can be finished in one visit once the problem is found. Finding and repairing a refrigerant leak, or replacing a coil or compressor, can take longer, especially if parts have to be ordered. Your technician will explain the timeline before starting.

If the outdoor unit hums but the fan won’t spin, the usual causes are a failed capacitor, a worn fan motor, or a contactor that’s stuck or burned. Turn the system off. Running it without the fan can overheat and damage the compressor. Call a technician; capacitors carry a dangerous electrical charge even when the power is off.

On the hottest, most humid Chicago-area days, a properly sized system may run nearly nonstop, and that’s normal. If it runs constantly but the house never reaches the set temperature, check for a dirty filter, a dirty outdoor coil, low refrigerant or leaky ducts. A tune-up or diagnostic visit can find the cause.
