About D&C A/C Service LLC
D&C A/C Service LLC operates as a San Antonio-based air conditioning contractor with a 4.4-star rating drawn from 12 client reviews. The company handles residential cooling systems, including diagnostic services, component replacements, and routine maintenance for central air units. Technicians employed by the company serve homeowners throughout the San Antonio metro area, with particular experience addressing cooling failures that follow the region\'s frequent summer thunderstorms and intense heat spells.
The company distinguishes itself through technician knowledge and hands-on problem-solving. Reviewers consistently note that the lead technician, Eric, demonstrates thorough diagnostic skills and explains repair options without aggressive upselling. While the company does not market exclusive brand partnerships or specialized rebate programs, its strength lies in completing defined repairs cleanly, including outdoor unit hose-downs that customers describe as surprisingly thorough for a service call.
Homeowners who contacted D&C A/C Service during cooling emergencies report positive outcomes. Maria Zeitz described how Eric arrived after storm damage last year and got her system running again, then returned this year to install a replacement unit while working through flexible payment options during her financial difficulty. Another reviewer, Takuya Sugi, documented how Eric replaced a faulty capacitor and cleaned the outdoor coil, achieving proper cooling without recommending the more extensive repairs the diagnostic initially flagged.
What Customers Say
Positive reviews cite Eric\'s diagnostic skill, honesty about which repairs are truly necessary, and friendly demeanor. Negative reviews mention unexpected cost additions and the technician recommending expensive upgrades, though most acknowledge the actual repairs work properly.
