Serving Bunker Hill and Coos County
One of the most common — and costly — errors in HVAC installation in Bunker Hill is oversized equipment. A furnace or AC system that's too large for the home short-cycles: it reaches the set temperature quickly, shuts off, and restarts frequently instead of running in longer, more efficient cycles. Short-cycling reduces comfort, increases energy consumption, accelerates component wear, and reduces system lifespan. Proper equipment sizing requires a Manual J load calculation that accounts for Coos County's climate data, your home's insulation, window area, ceiling height, and occupancy. Contractors who size by square footage alone are guessing.
Coos County's marine climate creates HVAC conditions that are mild in temperature but persistent in humidity and, for coastal installations, corrosive from salt air exposure. Condenser coil degradation in Bunker Hill is measurable over 3 to 5 years without protective maintenance.
Bunker Hill sees approximately 600 cooling degree days in summer and 6,380 heating degree days in winter, with real seasonal demand on both systems. Coos County homes built around 1979 — the local median — are at the age where original HVAC equipment is entering the replacement planning window.
