Getting Your HVAC System Ready for Louisville's Humid Summers

Louisville summers are no joke. Between high temperatures and relentless humidity, your HVAC system doesn’t get a break. Prepping your system before the heat kicks in can make a big difference in your comfort, energy bills, and peace of mind. Here’s how to get ahead of the season:

1. Start With a Professional HVAC Tune-Up

Even if your system seems to be running fine, an expert tune-up can catch small problems before they become big ones.

A thorough inspection typically includes:

• Checking refrigerant levels
  
  
• Cleaning condenser and evaporator coils
  
  
• Inspecting electrical connections
  
  
• Lubricating moving parts
  
  
• Verifying proper airflow
  
  

Louisville’s heat and humidity put extra strain on HVAC units, so professional maintenance helps extend the life of your system and keeps it running efficiently all summer.

2. Replace Air Filters and Clear Vents

A dirty air filter means your system has to work harder, which shortens its lifespan and reduces air quality. Swap out your air filter at least every 1–3 months during the summer.

Also:

• Make sure vents and registers are open and unblocked by furniture or curtains
  
  
• Vacuum around vents to reduce dust buildup
  
  
• Check outdoor units for leaves, debris, or overgrown grass
  
  

3. Seal and Insulate to Keep Humidity Out

Humidity is one of the biggest energy-drainers for your system. If warm, moist air is sneaking in through gaps and cracks, your AC has to run longer to keep up.

• Seal gaps around windows and doors
  
  
• Add insulation where needed, especially in older homes
  
  
• Consider a dehumidifier if your home feels sticky even when cool
  
  

4. Upgrade Your Thermostat for Smarter Cooling

Programmable or smart thermostats let you control your cooling more efficiently. You can set schedules, monitor usage, and adjust settings remotely—perfect for unpredictable Louisville weather.

Bonus tip: Set your thermostat a few degrees higher when you're away during the day. Every degree matters for energy savings.

5. Know When It’s Time to Call in the Pros

If your system is making unusual noises, struggling to cool your space, or causing high energy bills, don’t wait. Small problems can quickly turn into expensive repairs—especially in peak summer heat.
