Spring HVAC Checklist: Preparing for Summer

As the days get longer and the chill of winter fades, it’s time to prepare your HVAC system for summer. If you want cool air when it counts, spring is the season to act. Whether you’re trying to lower energy bills or avoid an emergency AC repair in the middle of a July heatwave, a little spring maintenance goes a long way. Let’s break down exactly how to prepare HVAC for summer—and how Infinity Heating & Air can help you stay comfortable all season long.

Why Spring HVAC Maintenance Matters

Spring may feel mild, but it’s the calm before the heat. A well-maintained HVAC system is essential for managing energy costs, extending system life, and maintaining consistent indoor temperatures through spring fluctuations and hot summer months.

The Seasonal Shift Impacts Your System

Your HVAC system’s been working hard all winter keeping your home warm. Now it needs to switch gears. That transition can reveal and worsen issues like clogged filters, dusty ductwork, or refrigerant leaks. When you skip spring prep, you might be saying yes to a whole lineup of issues, like spiking energy bills–or even system failure, that you never wanted to sign up for.

HVAC System Checklist for Spring

To bypass all the summer headaches and discomfort that come from an uncared-for HVAC system, here’s a simple list of some things you can do to help your system stay efficient and your home comfortable:

Replace or Clean Air Filters

Dirty air filters restrict airflow and force your system to work harder, reducing efficiency and increasing your electric bill. Replace filters every 1–3 months depending on your home and filter type.

Inspect the Thermostat Settings

Check your programmable thermostat or smart thermostat settings to match your seasonal needs. If you haven’t yet made the switch to a programmable model, spring is a great time; according to the Department of Energy, it can save up to 10% a year on cooling.

Clean Around the Outdoor Unit

Leaves, twigs, and dirt around your outdoor unit can block airflow. Clear a two-foot radius and gently hose down the unit (power off first!) to remove debris and improve performance.

Check for Leaks or Obstructions in Ductwork

Visible gaps or disconnected sections in your ducts reduce airflow and waste energy. Our team offers on-site custom ductwork, ensuring a tight fit that keeps the air where you want it.

Test the AC System Before Summer Starts

Spotting problems early means you’ll have time to schedule a pre season HVAC tune-up before demand spikes. Run your AC unit for 10–15 minutes and check for:

• Strange noises
• Weak airflow
• Bad smells
• Delayed start-up

Clear and Inspect Vents and Registers

Make sure all vents are unblocked and free of dust. Vacuum registers to improve air quality and airflow.

Schedule a Professional Tune-Up

Some aspects of HVAC maintenance are better left to the pros. A professional tune-up goes beyond what you can handle at home and ensures your system is ready for the summer months ahead.

Here’s why it matters:

• Prevent breakdowns by catching small issues early
• Improve efficiency and lower your energy bills
• Extend your system’s lifespan with proper care
• Protect your warranty, which often requires professional maintenance
• Get expert insight on how to improve comfort and air quality in your home

What Is It and Why It’s Critical

A pre season HVAC tune-up is like an oil change for your comfort system. It prevents breakdowns, keeps your system efficient, and extends the life of your investment.

What Professionals Actually Check

During the inspection, an inspector will:

• Check refrigerant and charge
  
• Clean condenser and evaporator coils
  
• Test voltage and amperage
  
• Inspect electrical connections
  
• Calibrate thermostats
  
• Clear the condensate drain
  

How Tune-Ups Save Money

Catch issues early before they become emergency calls. Regular maintenance can reduce energy bills and help your system last years longer

Signs Your HVAC System Needs More Than a Tune-Up

When to Repair vs. Replace

Not sure if your system is ready for summer or overdue for an upgrade? Most issues can be put right with just a repair, but if your system is over 12-15 years old, its repairs are costing more than half the price of a new unit, or it uses R-22 refrigerant (which is now outdated), it’s time to consider a replacement.

Strange Noises, Odors, or Uneven Cooling

Grinding, banging, musty smells, or hot spots in the house could mean failing components or insulation issues.

Rising Energy Bills Without Explanation

If your energy bills are climbing and your usage hasn’t changed, your HVAC system could be the cause.

DIY Maintenance vs. Professional Service

DIY OKs

• Filter replacement
  
• Clearing outdoor debris
  
• Wiping vents
  
• Adjusting thermostat settings
  

What Should Always Be Left to the Pros

• Electrical components
  
• Refrigerant handling
  
• Deep cleaning coils
  
• Internal diagnostics

Special Considerations for Western Washington Homes

Pollen, Rain, and Coastal Humidity

Our region’s damp spring conditions can contribute to mold, mildew, and allergens inside the home. Spring prep isn’t just about cooling; it’s about air quality and comfort.

Local Ductwork Challenges and Why On-Site Fabrication Matters

Older homes or remodeled spaces may have oddly shaped duct runs. Infinity’s on-site custom ductwork ensures a precise fit and better airflow customized for your home, right on the spot.
