OnSite Heat & Air is a locally owned HVAC company specializing in high-end custom home HVAC design and installation throughout Oklahoma. We partner with premier home builders to deliver comfort systems that are engineered with precision, installed with intention, and built to perform at the highest level.

Our process begins with a highly personalized bidding and system design approach. Each home is evaluated individually, with careful attention given to load calculations, duct design, airflow balance, zoning strategies, and efficiency goals. This allows us to create HVAC solutions that provide consistent temperatures, quiet operation, and refined comfort throughout the entire home.

We are especially focused on system performance beyond installation—properly sized equipment, balanced airflow, and well-designed zoning to eliminate hot and cold spots and support long-term reliability. Every system is commissioned with performance in mind, ensuring it operates exactly as intended once the home is complete.

Known for our exceptional level of care, OnSite Heat & Air delivers clean, organized installations, proactive communication with builders and trades, and meticulous attention to detail from rough-in through final startup. The result is a premium comfort experience that complements the craftsmanship of the home and exceeds homeowner expectations.

For builders who value quality, precision, and a true project partner, OnSite Heat & Air delivers elevated comfort—OnSite when you need us.
