D&T Heating & Cooling

D&T Heating & Cooling has served Bear, Delaware and surrounding communities since 2003, building a reputation grounded in technical expertise and genuine care for homeowners. The company holds a state HVAC license and employs certified technicians who handle installations, repairs, and preventive maintenance for heating and cooling systems. With 216 client reviews yielding a 4.9-star average, D&T works primarily in Bear and neighboring Newark, providing responsive service across New Castle County.

Unlike many contractors who juggle multiple trades, D&T focuses exclusively on residential heating and cooling, allowing technicians to develop deep specialization in system diagnostics and repair. The company offers an annual maintenance contract that includes scheduled tune-ups and priority scheduling, a benefit several reviewers specifically praised. This concentrate on HVAC, paired with same-day availability during emergencies, distinguishes D&T from general handyman services operating in the area.

Homeowners consistently describe D&T technicians by name, with Gary, Pat, and Tyler appearing across multiple five-star reviews. One Bear family recounted that after nearly three weeks without heat during winter, Gary and Pat diagnosed and repaired the system in a single visit, resolving issues a prior contractor had created. Another customer called D&T on a triple-digit summer day when her AC failed, and Gary arrived with a same-day appointment, explaining each repair step while completing the work efficiently. Multiple reviewers mention the owner Doug by name, noting his hands-on involvement with every job.
