There’s no better feeling than saying goodbye to chilly weather and hello to warmer days. But before you switch your air conditioning system back on for the first time, there are a few steps to take. After sitting idle during the cold months, your AC unit needs a little TLC to work properly and keep your home cool all summer. Skipping these steps could lead to higher energy costs, poor indoor air quality, or even costly breakdowns when you need cool air the most.
To help you get your air conditioner ready for the season, here’s what to do before turning on AC after winter.
1. Check the Thermostat and Circuit Breaker
Before turning on your AC for the first time after winter, start with the basics — your thermostat and circuit breaker.
- Set your thermostat to cooling mode. If you have a smart thermostat, adjust the settings so your AC system doesn’t work harder than it needs to. A good starting point is to set it a few degrees lower than the current room temperature and see if the system kicks on.
- Check the circuit breaker. If the AC was turned off at the breaker during the cold months, flip it back on. A tripped breaker could prevent your air conditioning unit from running, so make sure everything is powered up.
2. Inspect the Air Filter and Vents
If it’s your first time turning on the AC after winter, don’t forget to check your air filter and vents. Your air filter plays a huge role in how well your air conditioning system works. A clogged filter forces your AC to work harder, leading to higher energy costs and poor indoor air quality. Before turning on your AC, swap out the old filter for a fresh one.
While you’re at it, check the air vents around your home. Dust, pet hair, or other debris can block airflow, making your cooling system less efficient. Remove vent covers and clean them well. If you see excessive buildup in the ducts, it might be time to get them cleaned.
3. Give the Outdoor Unit Some Attention
The outdoor AC unit (also called the condenser unit) takes a beating during the off-season. Snow, leaves, and dirt can pile up around it, blocking airflow and making it harder for your air conditioner to work properly.
- Clear away visible debris. Use a broom or your hands to remove leaves, twigs, or other debris around the outdoor condenser unit.
- Inspect condenser coils. If they look dirty, spray them down with a garden hose (gently — no pressure washers).
- Check for damage. Look for missing external panels, bent fins, or visible wires. If anything looks off, it’s best to call a professional HVAC technician.
- Inspect condenser unit mounting bolts. If they seem loose, tighten them up to prevent unnecessary vibration or movement when your AC runs.
4. Check the Drain Line and Refrigerant Lines
Your AC’s drain line carries away moisture that builds up inside the system. Over time, it can clog with dirt and algae, leading to water leaks and even system failure. Before turning on your air, check the drain line and flush it if needed.
Refrigerant lines are another key part of your HVAC system. If you see signs of damage or wear — like frost buildup, leaks, or exposed ductwork — your AC may not produce cold air. A professional HVAC technician can inspect the coolant lines and recharge the system if necessary.
5. Test the System and Watch for Warning Signs
Once you’ve taken care of these steps, it’s time to fire up your AC and see how it runs. Switch your thermostat to cool, let the system run for about 15 minutes, and pay attention to how it performs.
- Does the air coming from the vents feel cool? If not, there could be an issue with the refrigerant or another component.
- Do you smell a musty odor when first turning on your AC after winter? A dirty AC filter or mold in the ducts could be the cause.
- Is there weak airflow? This could mean a clogged AC filter, blocked air vents, or a larger issue with the AC unit.
- Is the system making strange noises? Grinding, rattling, or buzzing sounds could signal a loose part or failing component.
