Serving Bonners Ferry and Boundary County
An AC system operating with even a 10 percent refrigerant undercharge can see a 20 percent reduction in cooling capacity and a measurable increase in energy consumption. In Boundary County, where AC systems run under sustained load, this degradation compounds across the cooling season — increasing utility costs while reducing system lifespan. Refrigerant charge verification using superheat and subcooling measurements, not just pressure gauges, is the standard that separates thorough HVAC maintenance from a check-the-box service call.
Boundary County's climate divides cleanly between heating and cooling seasons — cold winters that load furnaces for 4 to 5 months, and warm summers that put real demand on AC systems. Both systems fail most often at the start of the season they haven't run since the prior year.
Bonners Ferry sees approximately 1,320 cooling degree days in summer and 4,370 heating degree days in winter, with real seasonal demand on both systems. Boundary County homes built around 1982 — the local median — are at the age where original HVAC equipment is entering the replacement planning window.
