Engineering breakdowns of modern climate control: cold-climate heat pumps, geothermal systems, energy recovery ventilators (ERV), and smart zoning.
Compare variable-capacity inverter heat pumps against 98% AFUE condensing gas furnaces: SEER2 ratings, COP at -15°F, operating costs, and decibels.
Architectural integration of mini-split systems: concealed slim-duct air handlers, branch box refrigeration, line set concealment, and individual room zoning.
Eliminate PM2.5, wildfire smoke, and VOCs: whole-home HEPA bypass filtration, deep 5-inch MERV 16 media, ERVs vs HRVs, and active relative humidity control.
Complete engineering guide to residential geothermal heat pumps: vertical borehole loops, COP 4.5+ thermodynamic efficiency, drilling costs, and federal tax credits.
Design guide for in-floor hydronic radiant heating: PEX tubing layouts, manifold balancing, modulating gas boilers vs air-to-water heat pumps, and flooring compatibility.
