Claim This BusinessAbout DesignAir Of Texas LLC
DesignAir Of Texas LLC operates as an HVAC design specialist serving Dallas-area homeowners alongside contractors, builders, and architects throughout North Texas. The firm focuses exclusively on system design rather than installation work, offering load calculations via ACCA-approved Manual J methodology, precision duct layout design, and equipment selection services. With a 3.7-star average drawn from three client reviews, the company maintains a specialized niche assisting property owners navigating the city of Allen's permitting requirements and ensuring code compliance for new HVAC installations.
The company distinguishes itself through technical expertise cultivated in academic settings. The owner serves as a full-time HVAC instructor at a regional community college, teaching both introductory students and seasoned technicians about ACCA protocols including Manual J load calculations, Manual D duct design, and Manual S equipment selection. This educational background positions DesignAir to interpret the 2018 IECC requirements that mandate professionally calculated HVAC sizing for all new residential installations. The firm also advises clients on high-efficiency systems capable of delivering measurable energy savings alongside traditional and ductless configuration options.
Client experiences reveal varying levels of responsiveness worth noting. Reviewer Gustavo Rocha praised the company's reliability, knowledgeability, and prompt communication, recommending the firm without reservation for design work. However, reviewer Greg Myers reported significant difficulties, citing code violations discovered during city of Allen inspections that necessitated a costly redesign, with multiple unsuccessful attempts to reach owner Chris Noonan for resolution. Prospective clients should weigh this contrast when evaluating service expectations.
What Customers Say
One homeowner awarded five stars for reliable, knowledgeable service while another assigned one star after city inspectors found code violations and received no response to multiple resolution attempts. The mixed feedback averages to 3.7 stars across three reviews.
