 When things go wrong with your furnace on a cold winter night, you need fast, reliable solutions and immediate results. Intelligent Service’s expert technicians provide world-class service and real world solutions to your heating needs.



The thermostat is “the brain” of your heating system. When it’s not functioning properly, your home temperature becomes unreliable. We inspect and test thermostats, and can fix existing and install new systems as needed (including digital systems).



With forced heat comes dry air that cracks your skin and leaves allergens floating in the air. A properly installed and maintained humidification system allows you to keep the proper level of moisture in the air to maintain comfort and health all winter long.

“Outstanding service all around. They got me on the schedule super quick. Even called me the morning of the appointment to let me know that my tech could be running late because of some emergency calls. Still made it within the time window. Not only did he fix my issue but walked me through the house and explained my overall service since this was a recently purchased house. Couldn’t have been happier with the service.”
