New Construction & Building Science

The most comfortable, efficient homes are designed that way from the start. New construction and major renovations are where building science pays off the most — and where most comfort problems are quietly built in when corners get cut.

Andrew Ellis Heating & Air partners with builders and homeowners to design HVAC the right way: Manual J load calculations, Manual D duct design, and complete residential mechanical plans. We verify the results with blower-door and duct-blaster testing, so the home performs the way it was drawn — not just on paper.

Getting the design right before the walls close up means fewer callbacks, lower energy bills, and a home that's genuinely comfortable in every room for its entire life. It's the work we're known for, and the work we love most.
