Heating and cooling service in Cottage Grove
From established neighborhoods near the river to newer developments along Highway 61, Cottage Grove homes run a wide range of equipment. Our technicians inspect the complete system—equipment, airflow, ductwork, and controls—before recommending a repair or replacement.
Furnace, boiler, and heat-pump repair
Call when the furnace fails to start or cycles constantly, rooms stay uneven, a boiler leaks or loses pressure, or a heat pump cannot maintain temperature in deep cold. We diagnose the root cause and explain repair versus replacement in plain terms.
If equipment has reached the end of its life, we help compare properly sized furnaces, boilers, and cold-climate heat pumps. Financing options are available for qualifying projects.
AC repair, replacement, and ductless
Warm air, weak airflow, water near the indoor unit, and short cycling are common cooling complaints. We repair and maintain central air conditioners and install replacements when older units are no longer dependable.
Ductless mini-splits work well for additions, sunrooms, and finished spaces without ductwork. Whole-home humidifiers, dehumidifiers, and air cleaners help manage river-valley humidity and winter dryness.
