Rust on the outside usually means something's been overlooked on the inside. ⚙️
Commercial units work hard year after year, and it's easy to forget about them when they're tucked away on the side of the building. That weathered look can hide worn components, aging electrical connections, and refrigerant lines that need attention. Catching those issues early with routine HVAC service is a lot cheaper than an emergency breakdown mid-season.
Whether your building runs one Carrier unit or a dozen, H&K HVAC provides HVAC repair and maintenance for businesses in Chicago and the nearby suburbs. We handle everything from air conditioning repair on older systems to air conditioning installation when a unit has simply run its course.
Here's what we look for on commercial equipment:
✔ Rust and corrosion around electrical housing
✔ Worn fan motors and loose connections
✔ Insulated refrigerant lines that are breaking down
Don't wait for a complaint from the top floor. Reach out to H&K HVAC and get your commercial system checked while the weather cooperates.
