CRNE'S Environmental Control

CRNE'S Environmental Control has maintained a stronghold in Northbrook for 36 years, earning a 4.9-star rating across 178 verified reviews. This Carrier Factory Authorized Dealer operates around the clock, handling residential and light commercial projects throughout the Near North Suburbs including Deerfield, Wheeling, Highland Park, Lake Forest, and Glenview. Their NATE-certified technicians tackle everything from routine filter changes to full system overhauls, giving homeowners peace of mind whether they're facing a midwinter boiler failure or planning a springAC replacement.

What distinguishes CRNE from neighboring competitors is their dual credential as both a Carrier authorized dealer and an experienced handler of older equipment. They service systems dating back 25 years and beyond, offering honest replacement guidance rather than pushing unnecessary upgrades. Their indoor air quality division addresses Chicagoland humidity extremes through whole-home humidifiers and Respicaire air purification, while radiant floor heating and snow melt system installations serve clients seeking alternatives to traditional forced-air setups.

Homeowners who called during emergencies consistently praise Al, who diagnosed a complicated rooftop condenser issue a new condo purchaser couldn't resolve, and Tom, who arrived on a rearranged schedule and provided transparent explanations. One reviewer noted Al arrived within an hour of their Saturday call during bitter cold, explaining the problem honestly before completing the repair. Another highlighted technician Goo's ability to restore a failing AC unit by noon after a morning request, crediting both technical skill and genuine honesty.
