Heating Maintenance

In the Chicagoland Area

Serving Your Chicagoland Home

Your furnace requires routine care to continue running efficiently, extend its life span, and avoid costly repairs. A lack of regular maintenance can raise energy costs, negatively impact indoor air quality, and make your home uncomfortable. Often, regular furnace maintenance is required on units to maintain warranty coverage. At Black Diamond, we recommend scheduling an annual tune-up of your heating equipment.

What’s Included in Furnace Maintenance?

Our services include but aren’t limited to:

Testing and adjusting the burners for maximum efficiency
Inspecting the heat exchanger
Inspecting and adjusting the ignition system
Calibrating the blower assembly
Testing the thermostat
Replacing the filters
Testing for continuity and amp draw across the blower motor

Furnace Maintenance Plans

Because we feel so strongly that every home should have annual HVAC maintenance, we’ve designed an exclusive membership program that does just that. Our Crystal Club program offers two- and three-year options for equipment maintenance, discounts, and more.

24-Hour Heating Service

Black Diamond is proud to provide emergency service 24 hours a day, seven days a week. We also offer flexible weekday scheduling, and Saturday is a regular working day for us to accommodate busy families.

Chicagoland residents have chosen us for exceptional HVAC services for years. You’ll always speak with a Black Diamond team member when you call us, never an answering service or machine.
