D's Air & Heating, INC

D's Air & Heating, INC has served Chicago's heating needs for over 25 years as a family-owned contractor based at 5401 S. University Ave. The business holds an active HVAC license and maintains an A+ rating with the Better Business Bureau, complementing the 4.6-star average across 80 customer reviews. Operating 24 hours Monday through Friday with Saturday morning appointments, D's responds to emergency calls across the South Side, from Hyde Park to Bridgeport and Beverly, ensuring residents never face a Chicago winter without working heat.

What distinguishes D's is the direct involvement of owner Daryl Krogh, who brings technical certifications in both Lennox and Carrier systems along with in-house diagnostic capabilities. Unlike larger operations that subcontract labor, every technician on D's service fleet performs installations and repairs in-house, allowing for same-day estimates on equipment replacements. The shop maintains parts inventory for common repairs, meaning many calls resolve during the initial visit rather than requiring a second trip. This vertically-integrated approach translates to competitive pricing, as evidenced by customer Timothy Racine's comparison showing D's beat three competitor bids on a 2-ton AC replacement.

Customer reviews repeatedly highlight Daryl and his team navigating challenging scenarios with steady communication. Inge Krogh's furnace failure during a December snowstorm required multiple diagnostic visits over several days, with D's keeping her informed at each step rather than leaving her guessing. Pastor Michael Murray's 25-year relationship with Daryl reflects the trust built through consistent service quality across generations. Carolyn Carroll's review specifically credits D's with correctly diagnosing a Lennox unit that four previous service calls from another contractor failed to resolve, completing the repair on a second visit. These scenarios illustrate why Chicago homeowners recommend D's Air & Heating when heating systems fail.
