A Guide to Preparing Your AC for Summer

As the days grow longer and the temperatures begin to climb, your home’s air conditioning system becomes a critical part of maintaining comfort and peace of mind. Preparing your AC for summer isn’t just a smart move—it’s essential for preventing costly breakdowns, avoiding surprise repairs, and keeping energy bills manageable.

From cleaning air filters to checking ductwork and fine-tuning your thermostat settings, this guide walks you through everything you need to know about getting your system in top shape for the summer months ahead. With a bit of attention now, you can ensure cool comfort when it matters most—without the stress of mid-season malfunctions.

Clean or Replace Air Filters

Your air filter acts as a barrier, trapping dust, dander, pollen, and other airborne particles before they enter your HVAC system. When this filter becomes clogged, it restricts airflow, makes your system work harder, and ultimately reduces efficiency. Over time, this added strain can cause unnecessary wear and tear.

To prevent this, inspect your filters monthly and clean or replace them every one to three months. If you have pets, allergies, or live in a dusty area, consider replacing them even more frequently. Maintaining clean filters improves indoor air quality and keeps your cooling system running at its best.

Check Thermostat Settings

A properly functioning thermostat is key to maintaining a comfortable temperature in your home without overworking your system. Adjusting your thermostat just a few degrees while you’re away can result in significant energy savings. For optimal results, program it to lower the temperature shortly before you return home.

If you’re using a smart thermostat, explore features like geofencing, learning schedules, or remote access through a mobile app. Also, verify that the thermostat is accurately reading the room temperature to prevent unnecessary run times. These small tweaks help balance comfort and energy efficiency.

Clean Condenser Coils and Outdoor Unit

Your AC’s outdoor condenser unit is exposed to dirt, leaves, pollen, and other debris. This buildup can cling to the coils, blocking airflow and reducing the system’s ability to release heat. A clogged condenser can overheat and fail right when you need it most.

To clean the unit, turn off the power at the breaker, remove any visible debris, and gently spray the coils with a garden hose. Avoid using high pressure, which can bend the fins. Also, trim vegetation at least two feet around the unit to maintain airflow. A clean condenser runs more efficiently and reduces the chance of system failure.

Inspect Ductwork for Leaks

Duct leaks allow cooled air to escape into unconditioned spaces like attics and crawlspaces. This not only reduces efficiency but also causes uneven cooling and higher energy bills. Even minor leaks can lead to substantial loss over time.

Look for loose joints, holes, or disconnected ducts. You may also notice hot spots in your home or hear unusual whistling sounds. Seal small leaks with foil tape or mastic sealant to ensure air reaches every room as intended. For larger issues, consider having a professional conduct a duct pressure test.

Annual AC maintenance helps you avoid costly repairs and reduce energy bills. Discover the key benefits and what to expect from HVAC service.

Schedule a Professional Maintenance Check

While DIY steps make a big difference, a professional inspection is crucial for thorough, preventative care. A trained HVAC technician can catch problems early, test your system’s performance, and make adjustments that go beyond basic upkeep.

Expect a full inspection, including refrigerant level checks, electrical connection tightening, lubrication of moving parts, drainage checks, and airflow assessments. This visit is also a great time to ask questions and make sure your system is equipped for the upcoming heat. Regular summer AC maintenance protects your investment and keeps your system ready to perform.

Energy-Efficiency Tips for Extra Cooling Power

Even a top-performing air conditioner benefits from some support. Incorporating energy-efficient practices into your daily routine helps reduce the strain on your system and cuts down on utility costs:

Run ceiling fans counterclockwise to enhance air circulation.
Block heat by closing blinds and curtains during the day.
Cook meals early or late to avoid heating up your kitchen.
Use weatherstripping to seal leaks around windows and doors.
Set smart thermostats to adjust temperatures automatically based on occupancy.
Upgrade insulation in attics or crawlspaces to retain cool air longer.
Replace aging appliances with ENERGY STAR® models to ease the system’s load.

These simple habits amplify your AC’s efforts and contribute to a more sustainable household.

Common Questions About Getting Your AC Ready for Summer

Getting your air conditioner summer-ready can raise a lot of questions, especially when you’re trying to avoid breakdowns and maximize efficiency. Here are answers to some of the most common concerns.

How can I make sure my AC doesn’t break during a heatwave?

Preventative care is your best defense. Clean filters, scheduled professional maintenance, and attention to airflow and refrigerant levels ensure your system isn’t overworked. Address minor issues early to avoid complete system failure.

What should I check on my AC before summer starts?

Replace filters, clean the outdoor unit, verify thermostat accuracy, inspect ductwork, and schedule a professional air conditioner check. These steps catch hidden issues and optimize performance.

How often should I have my AC professionally serviced?

You should aim for at least one professional service annually, ideally in spring before your system enters peak demand. Regular tune-ups preserve energy efficiency and help identify worn or failing parts.

Is it worth investing in a smart thermostat?

Smart thermostats offer convenience, improved efficiency, and long-term cost savings. They adapt to your habits, provide remote control via smartphone, and help avoid unnecessary cooling.

What are the signs that my AC might need repair?

Warning signs include warm air from vents, odd smells, loud noises, frequent cycling, weak airflow, and high electric bills. These could indicate low refrigerant, worn components, or electrical problems.

Can I clean my AC unit myself?

You can clean the exterior and surrounding area, replace filters, and rinse the condenser coils gently. However, deeper cleanings and inspections should be left to a certified technician.

Why does my AC run constantly?

Constant operation can signal thermostat issues, poor insulation, refrigerant leaks, or undersized systems. Have a professional diagnose the problem before your unit wears out prematurely.
