Marshville sits in southeastern Union County on US-74, about 15 miles east of Monroe. The town mixes older ranch-style homes near the Marshville Historic District with newer builds along the US-74 corridor — HVAC systems here range from aging R-22 equipment to modern variable-speed units, and we service all of it. Carolina summers hit Marshville with sustained heat and humidity from June through September, making a properly functioning AC system non-negotiable.
A furnace failure in a Union County winter can go from uncomfortable to dangerous quickly, especially if there’s a cracked heat exchanger involved. We treat heating calls as urgent and run after-hours dispatches because a cold house with a broken furnace isn’t a problem that waits until morning.
Common failures we diagnose: igniter burnout, flame sensor fouled with residue blocking ignition, pressure switch failures preventing startup, control board issues, and blower motor problems. We stock parts for the most common failures — igniters, flame sensors, pressure switches — so most repairs get resolved on the first visit. We also serve customers in Marshville Historic District and US-74 corridor, and most of Marshville falls within our regular service run out of Indian Trail.
