Krug & Sons heating and air conditioning

Krug & Sons heating and air conditioning has served the Knoxville area for over 15 years as a family-owned HVAC contractor specializing in residential system installations and repairs. With a 4.8-star rating across 84 customer reviews, the company operates Monday through Friday from 7 AM to 4 PM, providing service to homeowners throughout Knox County and surrounding East Tennessee communities. The business handles projects ranging from routine maintenance to complete system replacements, with particular experience in homes participating for the Weatherization Assistance Program.

What distinguishes Krug & Sons from other regional contractors is their involvement in renovation and new construction projects, completing installations for ongoing building projects throughout the area. Reviewers note the company has handled HVAC work for multiple renovation jobs, with customers citing communication, pricing transparency, and maintenance follow-through as consistent strengths. However, some customers report challenges with parts ordering timelines and warranty-related service callbacks, particularly on weatherization program installations.

Specific technician experiences surface in customer reviews, with one reviewer documenting a 65-day wait for a backed-ordered part with minimal communication from the shop. Another customer notes technician Jake was repeatedly requested for callbacks but did not respond. Positive reviews highlight successful multi-year relationships with the company for renovation projects, with customers praising system installation quality and post-install service responsiveness.
