Hearthstone Heating & Air Conditioning

Hearthstone Heating & Air Conditioning operates from 105 W 61st Street in Westmont, Illinois, delivering furnace and cooling services across DuPage County including nearby communities such as Downers Grove and Darien. The locally owned contractor holds an A+ rating from the Better Business Bureau maintained for over a decade, backed by 115 Google reviews averaging 4.9 stars. Every service call is handled by company-employed technicians rather than subcontractors, giving homeowners direct accountability from initial diagnosis through final repair.

This contractor partners with the Comfort 24-7 Network to offer a two-year 100% money-back satisfaction guarantee on new equipment installations, a rare commitment in the residential HVAC trade. Their technicians hold NATE certifications confirming competency across modern high-efficiency heating and cooling systems, and the company has earned the Carrier President's Award for operational excellence. The team also installs indoor air quality solutions including filtration and purification components, addressing growing homeowner concerns about dust, allergens, and airborne particulates.

Reviewers consistently mention a technician named Peter arriving within hours of their call. One homeowner described Peter driving out on a frigid evening when heat failed entirely, finding a creative workaround to restart an aging system rather than recommending immediate replacement. Another reviewer needed same-day service for a faulty central air conditioner during a summer weekend, Peter explained the problem, walked through the repair steps, and completed the work at a reasonable price. Multiple customers noted seasonal maintenance visits spanning several years, reflecting the kind of ongoing relationships that sustain neighborhood contractors.
