Frequently Asked Questions

Do you really not charge extra for nights, weekends, and holidays?

Correct. We use job-based pricing, not hourly rates. The quote we provide is your final cost regardless of when we complete the work. An emergency furnace repair costs the same whether we fix it on Tuesday at 2 PM or Saturday at 2 AM.

Which equipment brands do you install?

We install premium brands, including Carrier, Trane, Lennox, Bryant, American Standard, Rheem, and Mitsubishi for ductless systems. We recommend specific models based on your home's size, layout, existing ductwork, and efficiency preferences.

How long do HVAC systems typically last in Buffalo Grove's climate?

With proper maintenance, furnaces typically last 15-20 years, and air conditioners typically last 12-15 years. Buffalo Grove's temperature extremes put equipment under stress, making seasonal tune-ups important for longevity. Systems without regular maintenance often fail years earlier.

How quickly can you respond to an emergency?

We guarantee a technician at your door within two hours of your call, any time of day or night. Most Buffalo Grove customers see us even faster because our office is local.

Can you service my older heating or cooling system?

Yes. Our 54 years of experience mean our technicians have worked on equipment from every era. While we can't always source parts for older units, we'll make every effort to repair your system if it's economically feasible rather than replace it.
