We’ll let you know when we’re on our way

On the day of your appointment, you’ll receive a text message from us when our technician is 10-15 minutes out from your home. For your peace of mind, our techs travel in officially marked King service vehicles.


We inspect your heating system

Our technician will greet you at the door and answer your questions. Then, they’ll start by taking a thorough look through your system to see if there are any issues that need to be addressed prior to starting the tune-up.


We’ll start our 40-point tune-up

Many HVAC companies offer heater maintenance service in Chicago. However, few tune-ups are as thorough as ours. Our tune-up addresses all the key performance points of the system to ensure it’s ready for the winter ahead.


Our tech will run through a final checklist

Before leaving your home, our technician will run through a final checklist and confirm that your furnace is heating your home as expected. We’ll also calibrate your thermostat for maximum efficiency and comfort.
