King Heating, Cooling & Plumbing has earned a 4.8-star average across 1,157 verified customer reviews in Frankfort, Illinois. This family operated business provides 24-hour residential service covering heating, cooling, and plumbing systems. Reviews consistently describe the company as family-run, with homeowners noting they speak directly to local staff rather than an offshore call center. The company serves Frankfort and surrounding Will County communities, responding to both scheduled maintenance requests and emergency calls when furnaces or AC systems fail.
What distinguishes this contractor is its commitment to transparent diagnosis and repair options. Technician Tyler received specific praise for showing customers exactly what he found, presenting multiple repair paths with pricing, and respecting different budget constraints. Rather than recommending only expensive replacements, reviewers noted the technician explained what repairs might be needed now versus later. This approach reflects a broader company philosophy visible across positive reviews: no pressure tactics, no unnecessary upselling, just technical assessment followed by customer choice.
Customers calling with system emergencies describe rapid response times. When John Furlong's furnace failed during cold weather, the company returned the call the same day, assessed the situation personally, and had a technician install equipment the following workday. Becky Howard described two separate visits from technicians Dennis and Cole, noting both were equally invested in resolving her issue. The company also handles plumbing work beyond HVAC, including hot water heater installations.
What Customers Say
98% of reviewers assign 5 stars, citing transparency, fair pricing, and skilled technicians. Multiple customers specifically name Tyler, Dennis, and Cole as professionals who explained options without pressure. The two negative reviews focus on warranty disputes for older equipment rather than service quality. Emergency same-day response appears across three separate 5-star reviews.
