Heating and cooling service in Mahtomedi
Mahtomedi’s neighborhoods include mid-century homes, lake-area properties, and newer construction—each with different equipment and comfort challenges. Our technicians evaluate the whole system, including airflow, ductwork, and controls, before recommending the most practical repair or replacement.
Furnace, boiler, and heat-pump repair
Call when the furnace fails to start or cycles repeatedly, rooms stay uneven, a boiler leaks or loses pressure, or a heat pump cannot maintain temperature in deep cold. We diagnose the root cause first and explain repair versus replacement in plain terms.
If replacement is the better long-term choice, 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 signal a cooling problem. We repair and maintain central air conditioners and install replacement systems when needed.
Ductless mini-splits are a strong fit for lake homes, sunrooms, additions, and finished spaces without ductwork. Whole-home humidity control and air cleaning also help in lake-country homes.
