The equipment that goes into a home is bought once and lived with for
fifteen years. We work out what actually suits your house before anyone mentions a brand.
Most expensive mistakes in these categories are sizing mistakes, not brand
mistakes. Every guide shows the arithmetic so you can check it against your own house.
No scores, no invented testimonials, and no testing we did not do. Each
guide states exactly what it is based on, in plain words, before it recommends anything.
