AC Capacitor Replacement in Chicago, IL

AC capacitor replacement in Chicago, IL is one of the fastest repairs we do, and one of the most common on hot afternoons. The capacitor stores a charge that kicks the compressor and the outdoor fan motor into motion. When it weakens, the unit hums and won't start, or the fan needs a push with a stick to get going.

Heat is what kills capacitors. They sit inside the condenser cabinet, and on a 100 degree day that cabinet runs much hotter. A dual run capacitor rated 45/5 microfarads that reads 38 on our meter is on its way out, even if the unit still starts some days. A bulged or leaking top is the obvious sign.

Our crew discharges the old capacitor, matches the microfarad and voltage rating exactly, and checks the contactor while the panel is open, since pitted contactor points often fail alongside a weak capacitor. After the swap we read amp draw on the compressor to confirm it is starting clean.

If a bad capacitor was left too long, the (/services/compressor-repair) may have been straining. We check. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Capacitor Replacement 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.
How often should I get an AC tune up?
Once a year, in spring, before the first long stretch of hot weather. In long cooling season states, some homeowners book a second check in late summer. A yearly AC tune up catches weak capacitors, pitted contactors and clogged drain lines while they are still cheap fixes.
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
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.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
