TDH Mechanical, Heating and Cooling Contractors

TDH Mechanical, Heating and Cooling Contractors operates as a residential HVAC specialist serving the Chicago metropolitan area and surrounding suburbs, including Addison, Clarendon Hills, Elmhurst, and Oak Brook. The company maintains a 4.8-star average across 171 customer reviews, reflecting consistent service quality in furnace replacement, air conditioning repair, and boiler diagnostics. Their service window runs Monday through Friday from 7 AM to 6 PM, with Saturday availability until 2 PM for urgent calls.

The contractor distinguishes itself through brand partnerships with Carrier, Mitsubishi, and Navien, offering both traditional ducted systems and ductless mini-split configurations ideal for older brick homes and historic properties. Their product lineup includes Navien combi-boilers and tankless water heaters, alongside indoor air quality solutions such as UV air sanitizers. The company handles oil-to-gas conversions for homeowners upgrading from older heating systems, and provides commercial HVAC services for property management companies across their service territory.

Customer reviews highlight specific technicians who managed complex installations. A reviewer in a vintage brick structure described George and his team as detail-oriented during a November 2022 mini-split project involving two outdoor condensers and six indoor heads, noting minimal disturbance to interior spaces. Another review praised Wally and Jesus for replacing an AC and furnace in a private residence, describing their approach as efficient and straightforward. For a condo owner requiring Saturday installation due to travel constraints, the team accommodated the schedule and completed both furnace and central air installation in a single day.
