Claim This BusinessAbout Mr. Heatmizer Heating & Cooling
Mr. Heatmizer Heating & Cooling operates as a heating contractor serving Lindenhurst, Illinois and surrounding Lake County communities including Grayslake, Gurnee, and Waukegan. With a perfect 5-star rating derived from 58 client reviews, this locally owned business has built its reputation on honest diagnostics and responsive service. Owner Patrick oversees operations personally, ensuring estimates come from someone who understands both the technical and business aspects of every job.
What distinguishes Mr. Heatmizer from neighboring contractors is their authorization as a York Liberties dealer, a designation that grants access to premium residential equipment not available through standard distribution channels. Their Synchrony financing program makes new system installations accessible to homeowners who might otherwise delay essential replacements. Unlike many shops that recommend full system swaps, this team frequently identifies targeted repairs, like coil cleaning, that extend equipment life without unnecessary expense.
Customer reviews consistently name Patrick and Nick as the technicians arriving at homes within hours of emergency calls. One reviewer credits Nick with walking her through a thermostat issue over the phone before making the trip, uncommon in an industry often hesitant to offer free advice. Another describes Patrick recommending against a new furnace when cleaning the existing coil resolved the problem, saving thousands. For Sarah Barbier, whose installation required correcting code violations from prior work, the team spent 2.5 days completing what other contractors refused to touch.
What Customers Say
Every one of the four extracted reviews awards 5 stars, with three explicitly naming Patrick or Nick as the technician. Responsiveness appears prominently, two reviewers report same-day or sub-hour arrival times, while another praises Nick for phone-based troubleshooting before visiting.
