Your HVAC system works hard behind the scenes—cooling you down in summer, warming you up in winter, and filtering the air you breathe every day. But like any hardworking system, it needs regular maintenance to keep running at its best.
So how often should you schedule service? And what if you have a ductless mini-split? Let’s break it down.
Twice a Year Is the Standard
Most HVAC pros recommend servicing your system twice a year: once in the spring before the cooling season, and again in the fall before heating season kicks in.
- Spring maintenance focuses on your air conditioner or heat pump, checking refrigerant levels, cleaning coils, and testing performance before hot weather arrives.
- Fall maintenance gets your heating system ready for colder months, inspecting burners or heat exchangers, tightening electrical connections, and ensuring safe operation.
Whether you have a traditional furnace and central AC setup or a heat pump that does both, this twice-a-year schedule helps prevent breakdowns and extend the life of your system.
What Happens During a Service Visit?
A typical HVAC tune-up includes several key steps:
- Cleaning the evaporator and condenser coils
- Checking refrigerant levels and pressure
- Flushing the drain lines to prevent clogs
- Inspecting wiring, capacitors, and safety switches
- Changing or cleaning the air filter
- Testing system controls and thermostat calibration
It’s not just about performance—it’s about safety and efficiency. Even something as simple as a clogged drain or loose wire can lead to serious problems if ignored.
What About Mini-Splits?
If your home uses a ductless mini-split system, the same twice-a-year professional maintenance rule still applies. But mini-splits also need a bit of homeowner attention in between visits:
- Clean the indoor air filters every few weeks to prevent dust buildup and keep airflow strong.
- Check the outdoor unit regularly for leaves, grass, or debris that could block airflow.
- In cold climates, keep an eye on the outdoor unit during winter storms—snow and ice buildup can reduce performance or cause the system to shut down.
Mini-splits may be more efficient than traditional systems, but they’re not maintenance-free. Staying on top of care ensures they stay efficient—and keeps your warranty intact.
Signs Your System Needs Service Sooner
Sometimes, waiting for your seasonal checkup isn’t enough. Here are a few warning signs that it might be time to call a pro:
- Unusual noises or smells from your HVAC unit
- Higher energy bills without increased usage
- Uneven temperatures or weak airflow
- Constant cycling on and off
- Thermostat not responding properly
Addressing these issues early can help you avoid larger, more expensive repairs down the line.
Make Maintenance Part of Your Routine
It’s easy to forget about your HVAC system when it’s working—but regular service helps it keep working. A little attention twice a year goes a long way toward reducing energy use, improving comfort, and avoiding surprise breakdowns during extreme weather.
If it’s been a while since your last tune-up, now’s the time to get on the schedule.
