A long-awaited vacation should be all about relaxation and enjoying your time away. However, nothing can spoil the excitement like returning to a hot, stuffy home or discovering an unexpected AC problem. Taking a little time for vacation AC prep can give you peace of mind, protect your system, and help you avoid unnecessary energy costs while you’re gone.

Your air conditioner is one of the most critical systems in your home, especially in Florida’s heat. Even when you’re not there, it plays a vital role in controlling humidity, preventing mold, and safeguarding your belongings. Let’s look at what you should do before leaving to make sure your home stays safe and comfortable.

Adjust Your Thermostat Before You Go

A key step in vacation AC prep is setting your thermostat properly. While you don’t need to keep your home as cool as usual, you shouldn’t turn the system off completely. Keeping some airflow and moderate cooling helps prevent high humidity levels, which can damage furniture, warp wood, and encourage mold growth.

Set your thermostat to about 82–85 degrees. This temperature is warm enough to save on energy bills but cool enough to protect your home’s interior. If you have a smart thermostat, program it to resume normal cooling a few hours before you get back, so you return to a comfortable environment. If your system supports remote access, you can even adjust it on the go in case plans change.

Change Your Air Filter

Before leaving, make sure your air filter is clean. A clogged filter makes your AC work harder than necessary, increasing wear and potentially leading to system failures while you’re away. Dirty filters also trap more dust and allergens, which can circulate once you return and turn the system back to normal cooling.

Replacing the filter helps maintain good indoor air quality and keeps airflow consistent throughout the house. Our AC maintenance services include comprehensive filter checks and replacements, ensuring that your system is always operating at its best before an extended absence.

Check and Clear the Drain Line

Your AC system continuously removes moisture from the air, and this water exits through the condensate drain line. If this line becomes clogged, it can overflow and cause water damage to your walls, ceilings, or floors while you’re away. By the time you return, the damage might already be extensive and costly to repair. Flush the line with a simple solution of vinegar and warm water before you leave. This breaks up small blockages and helps prevent buildup. For homes with a history of drain issues or repeated shutdowns, scheduling a professional cleaning before a trip is a smart move. Keeping this line clear is a simple yet often overlooked part of vacation AC prep.

Inspect and Prepare the Outdoor Unit

Your outdoor condenser unit needs a quick inspection before any extended trip. Remove any leaves, twigs, or yard debris that could block airflow or get pulled into the fan. Check that panels are securely fastened and that there are no loose wires or signs of rust or corrosion.

In Florida, where sudden storms are common, a protective AC cover can help shield the unit from falling branches and heavy rain. Be sure to use a breathable cover designed for HVAC systems, as fully sealed covers can trap moisture and promote mold growth. Making sure your condenser is secure and clear protects your system’s most expensive components while you’re away.

Consider Using Surge Protection

Power surges can happen anytime but are more common during summer thunderstorms. A sudden voltage spike can damage your AC’s circuit board, compressor, or thermostat, leading to expensive repairs or even a full system replacement.

If you haven’t already, consider installing a dedicated HVAC surge protector. This device intercepts excess voltage before it reaches critical components. You can have it added during a routine AC installation or as part of an upgrade to your existing system. Surge protection is a smart, affordable safeguard that provides extra peace of mind during your vacation and beyond.

Final Walk-Through and Peace of Mind

Taking a few simple steps before leaving for vacation can make a big difference in protecting your home and your air conditioning system. Proper vacation AC prep reduces energy costs, avoids unnecessary wear on equipment, and helps ensure you come home to a comfortable environment. Rather than dealing with surprises or repairs when you return, you’ll have peace of mind knowing your AC system was cared for in advance.
