HVAC service for St. Mary’s Point homes
River communities include homes of different ages and layouts, so comfort problems are not always caused by the equipment alone. We evaluate airflow, controls, ductwork or hydronic components, equipment condition, and humidity before recommending the most practical next step.
Furnace, boiler, and heat-pump service
Schwantes repairs heating systems that fail to start, cycle too often, make unusual noises, or leave rooms cold. We also diagnose boiler leaks and pressure issues and service heat pumps that freeze, run constantly, or cannot maintain the thermostat setting.
For equipment approaching the end of its useful life, we provide replacement options based on the home’s load, distribution system, efficiency goals, and budget. Financing is available for qualifying projects.
Cooling and indoor-air-quality service
Call if an air conditioner produces warm air, airflow is weak, water appears near the indoor unit, or the system cannot keep up. We repair and maintain central AC equipment and install replacement and ductless systems.
Humidity, filtration, and ventilation also affect comfort in homes near the river. Our team services humidifiers, dehumidifiers, air cleaners, and related equipment.
