As the long, hot summer in Columbia and Lexington winds down, now is the perfect time to make sure your HVAC system is ready for the cooler months ahead. Fall might feel comfortable now, but early fall is when your heater, air ducts, and cooling components can start showing wear after months of intense heat and humidity. Taking action now can help prevent emergency breakdowns, lower energy bills, and extend the life of your system.
#1 What Happens to HVAC Systems After a Southern Summer

- High humidity + lots of run-time = stress on components: compressors, coils, filters.
- Accumulated debris, pollen, or dust can clog filters and ducts, reducing efficiency.
- Motors and belts may have worn down, making units noisier or less effective.
#2 Key Tune-Up Tasks You Should Prioritize

Task | Why It Matters |
Replace or clean air filters | Clean filters help airflow, reducing strain on your blower and improving indoor air quality. |
Clean outdoor condensing unit (coils, fins) | Dirty coils make your AC work harder; fall is a good time to clear leaves, dirt, and debris. |
Lubricate moving parts | To prevent squeaks, friction, and reduce wear before heater or fan motors get heavily used. |
Check ductwork & sealing | Gaps or leaks in ducts waste conditioned air. Sealing helps both heating and cooling. |
Inspect thermostat & controls | A bad thermostat can cause heating or cooling to run unnecessarily or unevenly. |
Test heater / furnace before first cold snaps | Better to discover problems early rather than in the first cold night. |
