Affton's Mid-Century Ranches All Share the Same Problems
The 1950s brick ranches that define Affton were built with undersized return-air ductwork and a single central return in the hallway. Drop a modern high-static furnace into that ductwork and the blower will short-cycle for the next 15 years. We add returns, we right-size, and we get these homes genuinely comfortable instead of just colder.
The other two calls we run constantly in Affton: condensate drains clogging in tight basement closets where the AC sits inches from the water heater, and 20-year-old condensers crammed against a fence line on the small lots off Weber and Heege — no clearance, no airflow, and a compressor running hot every July. Both are cheap fixes when caught early, and both are why we check clearance and drainage on every Affton service call.
