A Personal Guarantee From Dave Musial


My name is Dave Musial and I’m the owner of Four Seasons Heating, Air Conditioning, Plumbing, and Electric. I’ve created this page to give you my personal guarantee that I’m fully committed to your satisfaction and a job well done.

For over 50 years my family has worked tirelessly to build our reputation of trust and accuracy, and without customers like you, we couldn’t have grown to become Chicagoland’s largest and most trusted HVAC contractor.

I always tell my employees to treat every home as if it’s their own. Do what’s right, and always in the best interest of our customers.

At Four Seasons, we strive for 100% customer satisfaction, and 99% of the time we hit our goal. Being in over 250,000 homes per year, it would be silly of me to say we never make mistakes.

Mistakes are a part of life. But I can assure you that if we do make a mistake on your repair, we will happily refund your money in full and make it right. We also offer a 2 year 100% Satisfaction Guarantee, or your money back on all new installations.^

We spend an enormous amount time training our employees and providing continuing education to offer best-in-class service and accurate diagnostics for all your heating, cooling, plumbing, and electrical equipment. We have an internal double-check policy to help ensure accurate diagnosis of all HVAC repairs.

This is my personal guarantee to you.

In closing, I would like to thank you for your business and give you the peace of mind that Four Seasons is committed to your satisfaction. If you should ever feel otherwise, please call me direct at 773-284-6161 ext 5500. If your call is an emergency, please call 773-284-6161 and press #1 and my call center will assist you.

For All the Right Reasons,


Dave Musial
Owner & CEO
