Almost every summer breakdown we run in Spartanburg, SC was visible months earlier to anyone holding a meter. A run capacitor reads 8 percent under its rating in April and fails on the first 95-degree afternoon. The refrigerant charge drifts low through a pinhole leak and the system struggles a full season before the coil finally freezes. A flame sensor fouls gradually until the furnace picks the coldest night of the year to start locking out. Maintenance exists to catch this arc early, when the fix is a scheduled part swap instead of an emergency call.
Most of our service calls are for AC Repair and Furnace Repair. If something has stopped working, start there.
Warning Signs for HVAC Maintenance
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- Energy bills creeping up without any change in your habits
- Longer run times to get to the thermostat setting
- New noises when the equipment starts up
- A breakdown last season that arrived with zero warning
- Recently installed equipment whose manufacturer expects maintenance records
- Uncertainty about whether your system is in good shape or on borrowed time
- A filter you cannot recall replacing, or a musty odor at blower startup
- Nobody has opened up the system in over a year
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. At the first hint of a problem, call (864) 215-4948 for a fast inspection.
