About AC Repair & Service
AC repair covers everything that keeps your central air conditioner or heat pump cooling: refrigerant leaks and low charge, failed capacitors and contactors, seized compressors and fan motors, frozen evaporator coils, clogged condensate drains, and thermostat and control faults. Many “dead” systems are actually a single inexpensive part, the key is a technician who diagnoses correctly instead of replacing components by guesswork.
Our technicians arrive fully stocked and test the system end to end: electrical readings, refrigerant pressures, airflow, and the safety controls. You get a clear explanation of what failed, why, and the repair options before we touch anything, no jargon and no scare tactics.
We service all brands of central air and heat pumps, and because we also install systems, we can tell you honestly when a repair is the smart move and when an aging unit is throwing good money after bad.

We complete the fix, confirm the system is cooling to spec, and leave the work area clean.
Frequently Asked Questions
Check the simple things first: the thermostat is set to cool and the fan to “auto,” the breaker for the outdoor unit has not tripped, and the filter is not clogged. If it still will not cool, turn the system off so a low refrigerant charge or a frozen coil does not damage the compressor, then call us at (847) 497-8149. We offer 24/7 emergency HVAC service and prioritize no-cool calls during heat waves.
Common causes are low refrigerant from a leak, a dirty or frozen evaporator coil, a failed capacitor or compressor, or a clogged filter restricting airflow. A proper diagnostic pinpoints which one so you do not pay for the wrong repair.
It depends entirely on the failed component, a capacitor is inexpensive, while a compressor or refrigerant-leak repair is more involved. We provide an upfront, written price after diagnosing the problem so you can decide with full information.
It depends on what failed and on the shape of the rest of the system. Look at four things: which part failed (a capacitor or contactor is a small repair, a compressor or a leaking coil is a big one), whether the unit uses phased-out R-22 refrigerant, how often it has needed repairs lately, and whether it still keeps the house cool on hot days. We give you a price to repair and a price to replace so you can compare.
Yes. Along with AC repair, we service central air conditioners and heat pumps across Glenview. A yearly cooling tune-up, ideally in spring, cleans the coils, checks the refrigerant, airflow, and electrical parts, and catches small problems before the first heat wave. Ask about our maintenance agreements.
Once a year, ideally in spring before cooling season. Annual tune-ups catch small problems early, keep efficiency up, and protect your manufacturer warranty. Ask about our maintenance agreements.
Usually it is the condensate drain. Your AC pulls moisture out of the air, and that water runs away through a drain line and sometimes a small pump. If the line clogs or the pump fails, the water backs up and spills. A frozen evaporator coil can also drip as it thaws. Turn the system off, check the filter, and call us. We clear the drain, check the pump, and find out why the coil froze if that is the cause. We have top of the line diagnostics and leak detection equipment.
Ice on the indoor coil or the refrigerant line usually means too little airflow or too little refrigerant. A clogged filter, closed vents, or a weak blower starves the coil of warm air, and a refrigerant leak drops the coil below freezing. Turn the cooling off, run the fan only to thaw it, and change the filter. If it freezes again, there is likely a leak or an airflow problem that needs a diagnostic. Running a frozen system can damage the compressor.
On the hottest days a healthy system may run nonstop and still sit a little behind the thermostat setting. If it falls further behind, common causes are a dirty outdoor coil, a clogged filter, low refrigerant from a leak, a weak capacitor, leaky ductwork, or a system that is too small for the house. We test refrigerant pressures, airflow, and the electrical parts to find which one it is.
Yes, turn it off before it freezes. Running a system that is low on refrigerant or iced over can destroy the compressor, which is the most expensive part. Check the filter and the breaker, and if it still will not cool, call us at (847) 497-8149.
Usually within an hour, unless we're very busy. We offer 24/7 emergency HVAC service.
