HVAC Services Rising Sun MD | Call Green Source Mechanical

If your Rising Sun home's heat pump is stuck in one mode (only heating or only cooling), isn't reaching the set temperature, or you hear a hissing noise, the reversing valve may be the culprit. This critical component switches the refrigerant flow for seasonal changes. Our technicians perform thorough diagnostics to confirm the issue and provide expert valve repair or replacement to restore proper function.

High humidity in our area promotes algae and mold growth inside the drain line, leading to frequent clogs that can cause water leaks and system shutdowns. We offer preventative maintenance that includes clearing the drain line with specialized tools and applying an algaecide tablet. For active clogs, our team performs a thorough clean-out to prevent water damage and restore proper drainage to your system.

Bi-annual preventative maintenance is the best defense. For Rising Sun homeowners, our maintenance visit includes a specific check of the heat pump's reversing valve operation and a full inspection and cleaning of the condensate drain system. This proactive care helps catch small issues before they become major repairs, improves efficiency, and extends the life of your equipment in our local climate.
