Air Conditioning Repair

Summer is rapidly approaching, and with plenty of hot days ahead of us, every homeowner needs a great AC system to keep their home nice and cool. If you’re like most homeowners, you’ll be running your AC a lot during the summer, and if all that extra use causes your system to break down, you need to call Deljo Deljo Heating & Cooling. At Deljo, we provide comprehensive air conditioning repair in Lincoln Square and other areas throughout Chicagoland.

We repair all types and brands of AC systems, and no matter what kind of problem you encounter, call us and in no time, one of our NATE-certified technicians will be there to help. Our technicians are available 24/7 for emergency repairs because we know that on a hot summer night you need your AC system working so you can get a good night’s sleep.

Deljo Heating & Cooling has been in business since 1922, and for decades we’ve provided AC repair service for homes and businesses throughout Chicago and its suburbs. During that time we’ve worked on all kinds of systems, and we know you need to call in the professionals from Deljo at the first sign of trouble.

Here are some of the common problems we see, so be on the alert for any of the following.

Clogged Air Filter

A clogged air filter is a common cause of AC problems. The filter is there to protect the interior moving parts from dust and debris. A clogged filter can restrict the flow of air through the system leading to increased wear and tear, reduced efficiency and more.

Strange Noises

When your AC system begins making strange noises – squealing, hissing, gurgling or buzzing – that probably means something inside the system has gone wrong. If that happens, call Deljo at once, because running your system with broken parts only makes the situation worse.

Not Enough Cooling

If your home isn’t cooling, you need to call us immediately for repair service. The cause could be something pretty simple, like a clogged filter. Or, it could be caused by a more serious problem like a broken fan motor, low refrigerant or a broken compressor.

If your AC system isn’t working the way it should, keeping your home or business cool and comfortable, call Deljo at 773-829-4295 for fast, reliable and professional air conditioning repair in Lincoln Square and other areas of Chicagoland.

Joe was great. We came home to a cold house on a Sunday night and he came out to diagnose the issue right away. Very knowledgeable, very friendly.

We’ve been using Deljo for several years and have had a great experience with them. They’re prompt, reliable, and trustworthy. The technicians (David was the most recent) have been great.

Ari Telisman Chicago IL.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
