The Recommended HVAC Maintenance Schedule
Spring AC Tune-Up
Schedule your cooling system tune-up in March, April, or early May — before DC's hot, humid summer arrives. This gives you time to address any issues before you actually need the AC.
Fall Heating Tune-Up
Schedule your heating system tune-up in September or October, before the first cold snap hits. A fall tune-up ensures your furnace or heat pump is ready when you need it most.
What's Included in an HVAC Tune-Up
A professional HVAC tune-up from CoolHVAC includes:
- Full system inspection and safety check
- Cleaning of evaporator and condenser coils
- Refrigerant level check and adjustment if needed
- Lubrication of all moving parts
- Tightening of electrical connections
- Thermostat calibration test
- Air filter replacement
- Written summary of your system’s condition
What Happens If You Skip Maintenance?
Skipping maintenance doesn't just increase the chance of a breakdown — it also costs you money every month. A dirty, poorly maintained system works harder to achieve the same results, consuming more energy in the process.
Industry data shows that systems without regular maintenance can lose up to 5% of their efficiency per year. After five years without a tune-up, your system might be running at 75% of its original efficiency — which means higher bills and more wear on components.
Many manufacturers also require documented annual maintenance to honor warranty claims. Skipping service could leave you responsible for a repair that would otherwise be covered.
