Heating & Cooling Services in Northbrook IL

Your Heating and Cooling Expert

CRNE’S HVAC services (industry shorthand for heating, ventilation and air conditioning) are designed to meet each customer’s individual needs. Our expert contractors can repair or service any furnace, AC unit, or boiler, and when it’s time for an upgrade, we can recommend energy-efficient equipment that will be easy on your utility bills. As an authorized Carrier dealer, we offer a 100 percent satisfaction guarantee on any new Carrier product. Financing also may be available.

To keep your system running smoothly, CRNE’S also offers maintenance agreements intended to maximize efficiency and reduce the likelihood of breakdowns. For example, our technicians will perform more than 30 safety checks on your furnace, air conditioning unit, and water heater. Regular service should address the problems we see most in the field and help you avoid those preventable — and costly — repairs.

More than a HVAC Company

In addition to our many heating and cooling services, CRNE’S can repair and install sump pumps, water heaters and home generators. We make your comfort our priority! We also offer air quality services, including whole-house humidifiers and duct cleaning. These add-ons improve the way your systems work and will allow you to breath easier.
