ASC HVAC

ASC HVAC operates from Glenwood, Maryland, delivering residential and commercial heating and cooling solutions across Howard County and surrounding communities including Montgomery, Frederick, Carroll, and Prince George's counties. The company maintains 24-hour availability Monday through Friday, providing round-the-clock service for emergency repairs alongside scheduled installations and preventive maintenance. With a 4.7-star average rating drawn from 13 client reviews, the contractor has built a documented track record serving both homeowners and business property managers throughout central Maryland.

The business distinguishes itself through specialized indoor air quality offerings, particularly the iWave whole-house air purification system that requires no filter replacements or ongoing maintenance. Their service portfolio encompasses traditional split systems, heat pumps, and ductless mini-split configurations alongside custom ductwork design and fabrication. As a family-owned enterprise established in 1989, the company emphasizes straightforward pricing and transparent recommendations, reviewers consistently note that technicians advise against unnecessary replacements and suggest cost-effective solutions over high-pressure sales tactics.

Customer testimonials highlight specific service scenarios demonstrating responsive technical support. One reviewer describes calling on a sweltering Saturday when their air conditioning failed catastrophically; the dispatch team arrived the following day, diagnosing and repairing the issue in under forty minutes. Another review recounts a same-day summon during an approaching winter storm where a technician reached the property within thirty minutes and resolved a heat pump failure caused by a blown fuse. Multiple reviewers specifically commend individual technicians, Dan, Ryan, and Danny, for rapid response times, professional demeanor, and thorough system inspections performed during each service call.
