Air Conditioner Maintenance in Chicagoland

Serving McHenry, Kane, Lake, DuPage, Cook Counties and more!

As part of regular maintenance for your car, you get regular oil changes, tire rotations etc. The same is true for an AC unit. You don’t just install one and leave it. To keep your equipment lasting longer, running at peak efficiency, and avoiding costly repairs, you must perform regular maintenance on it. A lack of regular maintenance can raise energy costs, negatively impact indoor air quality, and make your home uncomfortable. Often, regular maintenance is required on units to maintain warranty coverage. At Black Diamond, we recommend an annual tune-up on your equipment.
