J M Heating & Cooling

J M Heating & Cooling has earned a 4.8-star rating across 48 verified customer reviews in Grayslake, Illinois. Owner and lead technician Joe Murray operates this locally-rooted company, responding to service calls across the northern Lake County region. The team maintains round-the-clock availability, ensuring residents of Grayslake and surrounding communities have access to emergency heating and cooling repairs regardless of the hour or holiday.

What distinguishes J M Heating & Cooling from regional competitors is Joe Murray's hands-on approach to every service call. Multiple reviewers recount instances where Joe traveled to Chicago to source hard-to-find replacement parts, completing repairs the same day rather than leaving homeowners waiting. His diagnostic process goes beyond the immediate complaint, one reviewer noted Joe proactively identified a rusted exhaust vent that posed a carbon monoxide risk, potentially saving the household from a life-threatening hazard. This preventive attention during standard repairs reflects the company's commitment to homeowner safety rather than simply completing the -cost fix.

Customer stories from the reviews illustrate the company's responsive nature. When Janine Harrison's furnace failed on New Year's Eve, J M Heating & Cooling arrived within an hour of her call, restoring heat before the holiday weekend concluded. Another homeowner, Taryn Mata, called regarding a malfunctioning furnace and received troubleshooting assistance over the phone before Joe even arrived on-site, demonstrating their willingness to help before a service ticket is even generated.
