AC Not Turning On in Chicago, IL

AC not turning on in Chicago, IL is a control problem more often than a mechanical one. The thermostat calls for cooling, nothing happens, and the house heats up. Our crew starts on the low voltage side because that is where the answer usually is.

The 24 volt control circuit runs from a transformer in the air handler or furnace to the thermostat and out to the condenser. A blown 3 amp fuse on the control board kills the whole thing. So does a float switch in the drain pan that tripped because the condensate line backed up. That safety switch is doing its job, and the real fix is clearing the drain line.

Other causes on our list: dead thermostat batteries, a loose wire at the thermostat base, a tripped breaker at the panel, a pulled disconnect at the outdoor unit and a failed transformer. On older systems we sometimes find a rodent has chewed the thermostat cable where it runs along the foundation.

We test each point with a meter and show you the reading. Call (866) 703-1217 when your AC not turning on leaves you guessing.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Not Turning On in Chicago, IL.

Talk to our crew
How much does central AC repair cost?
It depends on the part. A capacitor or contactor is a small repair. A refrigerant leak or a compressor is a much bigger one. We diagnose first, then give you the price before any work starts, so you decide with the number in front of you.
Can you just add refrigerant to my AC?
We can, but it rarely makes sense on its own. A central AC system is sealed, so low refrigerant means a leak. Topping it off without fixing the leak means the charge leaks out again. We find the leak, repair it and weigh in the correct charge.
Why does my AC keep tripping the breaker?
Common causes are a compressor struggling to start because of a weak capacitor, a shorted fan motor, a compressor with a winding shorted to ground, or loose and overheated wiring. Resetting the breaker over and over can make it worse. Leave it off and call us.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
What should I do before the technician arrives?
Check that the thermostat is set to COOL and below room temperature, check the breaker and the outdoor disconnect, and look at the filter. If there is ice, turn cooling off and run the fan. If there is a burning smell, shut the breaker off and leave it off.
