Renner Electric Heating & Cooling

Renner Electric Heating & Cooling has served Morristown and surrounding Hamblen County since at least 2014, building a steady base of residential customers who return year after year for new installations and routine service. The company maintains a 4.3-star average across 91 reviews and operates around the clock every day of the week, a schedule that lets homeowners in Jefferson City, White Pine, and Russellville call after normal business hours and still reach a live technician. License details and founding year are not publicly posted on their site, but the consistency visible across a decade of customer feedback suggests a crew with deep roots in East Tennessee weather and housing stock.

What distinguishes Renner from many regional contractors is the length of their customer relationships. Multiple reviewers cite a 10-year patronage with the same company, and several specifically note that Renner has honored product warranties without friction. The company installs complete split and mini-split systems, suggesting they work with more than one equipment partnership and can tailor recommendations to a home's size and layout rather than pushing a single brand line. Pricing language used by reviewers points to transparent estimates before work begins, which matters in a market where surprise charges are a leading driver of negative reviews.

When carbon monoxide alarms sent Travis Stansell's household into alarm on a cold night, Jacob Benfield arrived after hours to diagnose the furnace and returned the next morning with Casey to install a replacement unit before another cold snap arrived. Elijah earned a same-day call from Vern Campbell by responding to a flooded basement caused by a leaking AC unit, fixing the root problem and then vacuuming standing water without being asked. Across reviews, Benfield, Elijah, and Tyler each earned individual praise for technical knowledge and professional conduct, suggesting the company has invested in training multiple crews rather than relying on one lead technician.
