Summer is right around the corner, and that means one thing—your air conditioner is about to work overtime. The last thing you want is to be stuck in a heatwave with an HVAC system that’s struggling to keep up (or worse, completely broken down). The key to a cool, stress-free summer? A little pre-season maintenance.

By giving your HVAC system a quick check-up before the summer heat kicks in, you can prevent expensive repairs, improve energy efficiency, and ensure your home stays comfortable. Ready to get started? Follow this simple homeowner’s pre-season checklist to make sure your HVAC system is summer-ready.

Why Pre-Season HVAC Maintenance Matters

Think of your HVAC system like a car—if you ignore routine maintenance, it’s bound to give you trouble when you need it most. A little attention now can save you from bigger headaches later. Here’s why early maintenance is a must:

• Prevents unexpected breakdowns during peak summer heat
• Lowers your energy bills by improving efficiency
• Extends the lifespan of your HVAC system
• Improves air quality for a healthier home
• Keeps your home consistently cool and comfortable

Now, let’s break down exactly what you need to do before summer arrives.

Step 1: Check and Replace Your Air Filters

Your HVAC system’s air filter is like its lungs—it needs to be clean to work properly. Over time, dust and debris clog the filter, making it harder for air to flow. This forces your system to work harder, increasing energy bills and putting unnecessary strain on your unit.

What to do:

• Check your air filter and replace it if it looks dirty.
• If you have pets or allergies, consider replacing it more frequently.
• Use high-quality, pleated filters for better air quality.

This simple step alone can boost your system’s efficiency and improve the air you breathe.

Step 2: Inspect Your Thermostat and Adjust Settings

Your thermostat is the brain of your HVAC system. If it’s not working properly, your home won’t cool efficiently.

What to do:

• Check that your thermostat is set to “cool” mode.
• Test it by lowering the temperature a few degrees—your AC should kick on within minutes.
• If you have an old-school thermostat, consider upgrading to a smart thermostat for better energy savings.

Smart thermostats automatically adjust based on your schedule and temperature preferences, helping you save money on your energy bills while keeping your home comfortable.

Step 3: Clean Your Outdoor Unit for Optimal Airflow

Your outdoor unit (also called the condenser) is exposed to dirt, leaves, and debris all year long. If it’s clogged, it won’t be able to release heat properly, leading to poor performance and potential breakdowns.

What to do:

• Turn off the power to your AC unit.
• Remove any debris, leaves, or twigs around the unit.
• Use a garden hose to gently clean the condenser coils.
• Make sure there’s at least two feet of clearance around the unit for proper airflow.

Keeping your outdoor unit clean ensures your HVAC system can do its job without struggling.

Step 4: Test Your System for Any Unusual Sounds or Issues

Before summer hits full swing, turn your AC on and listen carefully. Your HVAC system shouldn’t sound unusual. Strange noises could indicate underlying issues.

Warning signs to watch for:

• Banging or clanking: Loose or broken parts inside the unit.
• Squealing or screeching: Belt or motor issues.
• Weak airflow: Possible ductwork or compressor problems.
• Warm air coming from vents: Could mean low refrigerant levels or a faulty compressor.

What to do:

• If you notice any of these signs, don’t ignore them.
• Contact a professional before the issue gets worse (and more expensive to fix).

Step 5: Schedule a Professional HVAC Tune-Up

Even if everything seems to be working fine, an annual HVAC tune-up by a professional is a game-changer. A trained technician can spot problems you might miss and fine-tune your system for maximum efficiency.

What’s included in a professional tune-up?

• Checking refrigerant levels
• Inspecting and cleaning evaporator and condenser coils
• Testing electrical connections and components
• Lubricating moving parts
• Checking airflow and thermostat calibration

Think of it as an annual health check-up for your HVAC system. It keeps your system running smoothly, reduces energy costs, and prevents breakdowns when you need cooling the most.

Bonus Tips for Keeping Your Home Cool All Summer

Beyond HVAC maintenance, here are some extra tricks to help keep your home comfortable:

• Use ceiling fans: They help circulate cool air, making your AC more efficient.
• Block out the sun: Close blinds or curtains during the hottest part of the day.
• Seal any air leaks: Check windows and doors for gaps that let cool air escape.
• Avoid using heat-producing appliances: Use ovens and dryers in the evening to prevent excess heat buildup.

These small changes can make a big difference in keeping your home cool and lowering your energy bills.
