Spring AC Startup Guide: What to Check Before the First Heatwave Hits

In 2024, three cities in the Greater San Francisco Bay Area saw the hottest summer in over 100 years of record-keeping. If you live in the area, your home needs the most reliable air conditioning system possible to handle rising temperatures and our warm Mediterranean climate. If you want to stay nice and cool before the first heatwave hits, it’s important to implement some spring AC maintenance tasks that’ll help you prepare for hot outdoor temperatures. The experienced team at TRIO Heating, AIR & Plumbing has some useful information about why spring is the best time to prep your AC, what you need to do, common problems to look for, and more.

Why Spring Is the Best Time to Prep Your AC

Skipping spring AC maintenance can cause performance problems and may result in emergency issues that require costly repairs. If you’re wondering how to prep your AC for summer and when to schedule AC maintenance, early spring is highly recommended. Here’s why spring is the best time to prep your air conditioner for the hotter months ahead:

• Shorter wait times: Since many people wait till summer to schedule AC maintenance, prepping your AC in spring helps you get ahead of the long wait times and beat the summer rush.
• Prevent breakdowns: Spring AC maintenance helps you identify and address minor issues early before they turn into stressful, costly emergency breakdowns during the middle of an oppressive heatwave.
• Lower energy bills: Getting a professional AC inspection before summer and keeping everything clean and well-maintained reduces wear and tear, which helps your system run more efficiently and saves you money on monthly energy costs.
• More accurate testing: The milder spring temperatures are best for technicians to test and calibrate your system accurately without overloading it or getting less accurate readings that could affect your comfort later.
• Better indoor air quality: Early spring air conditioner maintenance eliminates dirt, mold, and airborne pollutants that have accumulated over the winter, so your AC produces clean, fresh, and healthy air when it’s in use during the summer.

Your Step-by-Step Spring AC Startup Checklist

Following a spring air conditioner startup checklist makes it easier to prep for the summer heatwave. Use this step-by-step spring HVAC maintenance checklist to make sure that all of your bases are covered:

• Step one: Inspect the outdoor unit and remove any leaves, branches, twigs, and other debris that have built up over the winter to help maintain good airflow.
• Step two: Confirm that your outdoor unit is level and stable.
• Step three: Inspect and clean or replace your air filter, even if it appears clean at first glance.
• Step four: Make sure the condensate drain line is free of blockages, and gently remove anything that is clogging it.
• Step five: Visually inspect the AC fan and blower motor to look for dust and debris, and clean them as necessary or call TRIO for professional maintenance.
• Step six: If it’s the first time turning on your AC since winter, make sure you set your thermostat to “cool,” turn the system on, and confirm that the air inside your home reaches the temperature you selected, which should be lower than the current temperature.
• Step seven: Listen for unusual noises, sniff around for odors, and check for leaks coming from the AC unit, and call TRIO for professional repairs if you notice any of these issues.

Common Problems That Show Up After Winter

Homeowners should be aware of several early signs of AC trouble, so they can address them before the summer heatwave hits. Look for these common problems that often show up in air conditioners after winter:

• Leaves and other outdoor debris accumulate on the condenser unit, reducing airflow.
• Cold weather causes the AC’s seals to contract and crack, leading to a possible refrigerant leak.
• Clogged air filters cause the evaporator coils to freeze, reducing efficiency and performance.
• Winter moisture and/or cold temperatures cause electrical components to fail, leading to a malfunctioning AC system.
• Pests may chew through electrical wires during the winter, preventing the AC from turning on.
• Drain lines get clogged with debris, causing water to pool around the indoor unit.

Signs Your AC Needs Professional Maintenance

While there are some things you can do yourself, like change the air filter, there are times when your AC requires professional maintenance. You may notice:

• Poor or uneven cooling throughout your home.
• Lack of activation, even after flipping the circuit breaker.
• Strange, unusual noises or unpleasant odors.
• Suddenly high energy bills during the summer without a noticeable change in usage.
• There is visible water leaking or pooling around the air conditioner’s indoor or outdoor unit.

DIY Tips vs. Calling the Pros: What You Should and Shouldn't Do

What You Should Do

These DIY AC maintenance steps are fine to do yourself:

• Replace your dirty air filter every one to three months, or as needed.
• Gently clean the coils and remove debris from the outdoor condenser unit, and keep at least two feet around the unit clear.
• Make sure your indoor vents and registers are unobstructed and clean.
• Confirm that the thermostat is working and set to “auto” instead of “on” to keep the fan from constantly running.
• Carefully clear your condensate drain line to prevent algal buildup and blockages.

What You Shouldn’t Do

These AC maintenance tasks are best left to the professionals:

• Fixing refrigerant leaks and replenishing low refrigerant levels.
• Addressing major electrical issues that require handling wiring, circuit boards, and capacitors.
• Repairing or replacing any loose or malfunctioning components.
• Removing an old, inefficient AC and installing a new air conditioning system.
• Performing an indoor air quality test.
