ACE Heating & Cooling

ACE Heating & Cooling has served Crystal Lake and the greater northern Illinois region for over two decades, operating as a full-service residential mechanical contractor specializing in heating, cooling, and plumbing solutions. The company holds active licenses in both Illinois and California, maintaining a presence across a dozen Illinois communities from Chicago west to Algonquin and Lake in the Hills, while simultaneously serving Central Valley customers in California's Lodi and Elk Grove areas. Customer feedback collected across 61 reviews yields a 3.8-star average, with recent visitors noting both timely arrivals during emergency calls and recurring frustrations over installation quality control and communication practices.

What distinguishes ACE from regional competitors is their dual-state operation spanning nearly 1,800 miles, offering synchronized service contracts for seasonal snowbirds who maintain residences in both markets. The company operates as a Rheem authorized dealer and promotes geothermal heating and cooling systems as premium alternatives to conventional forced-air equipment. Their current promotional offer features a $19.97 system clean-and-check, targeting preventative maintenance rather than waiting for equipment failures.

Customer narratives reveal mixed experiences. One reviewer documented how ACE technicians completed a furnace and AC installation in 2021, but subsequent inspection by an independent HVAC technician identified multiple code violations including a missing gas-line drip leg and an improperly mounted humidifier. Another reviewer discovered a cracked vent pipe two years post-installation during routine filter maintenance, requiring outside repairs. The owner, Nick, was specifically named in both positive quoting interactions and negative service disputes, illustrating inconsistent customer touchpoints depending on which team member interacts with the homeowner.
