TDH Mechanical, Heating and Cooling Contractors

TDH Mechanical operates from St. Charles serving the Fox Valley region including Elgin and Batavia for over two decades. This licensed HVAC contractor maintains a 4.8-star average across 356 customer reviews, reflecting consistent service delivery in both residential and light commercial settings. Their suburban phone line at (630) 406-9082 handles scheduled calls while a separate Chicago number serves that metro area. Standard hours run 7 AM to 6 PM weekdays with Saturday availability until 2 PM, plus 24-hour emergency service for sudden heating or cooling failures.

What distinguishes TDH Mechanical is their product breadth and manufacturer partnerships combined with technical specializations not common among regional contractors. They hold certifications as both a Carrier dealer and Mitsubishi ductless mini-split installer, offering equipment from traditional split systems to Navien combi-boilers and tankless water heaters. Their oil-to-gas conversion service helps homeowners with aging heating systems transition to modern efficiency without full system replacement. Commercial capabilities include air duct cleaning and property management HVAC contracts, giving them versatility beyond typical residential-focused operations.

Customers repeatedly mention technician Wally by name, highlighting his hands-on approach as both salesperson and installation supervisor rather than a detached estimator. One reviewer noted Wally provided quotes and remained on-site throughout the installation process, ensuring quality control. Another customer described a same-day emergency call during a summer heat wave resolved with professional communication and thorough cleanup afterward. The recurring theme across positive reviews involves transparent pricing, skilled technicians, and respect for client property.
