What’s the Best AC Temperature for Your Home?

With fall in full swing and the heat of summer behind us, now’s a smart time to check in on how well your air conditioning system handled the demands of the season. If your home didn’t feel consistently comfortable, your AC ran more than expected, or you noticed signs like leaking or dripping, your AC temperature settings may be worth revisiting.

Setting the right temperature isn’t just about comfort, it plays a major role in how efficiently your system operates, how much you spend on energy, and how long your equipment lasts. Whether you’re using central air conditioning or exploring the best air conditioner brands for an upgrade, a little knowledge now can help you avoid bigger problems later.

Best AC Temperature for Energy Saving

Even though your air conditioner may not be running as much in October, setting the right AC temperature when you do need cooling, can still save energy and money. The U.S. Department of Energy recommends keeping your home around 68-70°F during cooler months for energy efficiency.

What we tell customers at Wilson’s is this: aim for comfort without overworking your system. If your thermostat is set too low, especially when it’s not necessary, it can lead to issues like frozen coils, excess humidity, or even leaks.

That’s especially true if you rely on central air conditioning, where the whole home’s airflow depends on a properly balanced system. When the AC runs more than it needs to, even during seasonal transitions, you’re not just wasting energy, you’re putting extra strain on your equipment.

What Temperature Should You Set Your Air Conditioner to in Fall?

As temperatures begin to level out, it’s a good opportunity to fine-tune your settings and make sure your system is still running as it should.

Even though you’re likely using your system less right now, it’s still a good idea to set your thermostat around 72°F or higher on warmer fall afternoons. That keeps the system from overworking unnecessarily and gives you a chance to observe any signs of lingering issues, like delayed cooling or unusual noises, before they worsen.

And if you found yourself setting the AC far below 70°F just to stay comfortable this past summer, it may indicate your system was working overtime to compensate for a maintenance issue.

Now is the right time to address those concerns with a seasonal AC inspection or repair. A quick tune-up in the fall ensures your home will be ready for the next heat wave, without the stress of last-minute fixes.

Common Causes of a Dripping AC Unit

Many homeowners notice a dripping AC unit during the hotter months and often forget about it once cooler weather rolls in. But if your system leaked, it’s worth understanding why, so it doesn’t come back worse next year.

The most common reasons include:

• Clogged condensate drain lines
• Frozen evaporator coils caused by low refrigerant or poor airflow
• Dirty air filters, which restrict circulation and trap moisture
• Thermostat set too low, causing excess condensation

In some cases, an AC that leaks water inside the home can lead to ceiling damage, mold growth, or more serious repairs. Overworking your system or neglecting routine maintenance is a major cause of avoidable AC issues, including leaks and short cycling.

If your unit dripped at any point this summer, don’t wait until spring to deal with it. Fall is the ideal time to schedule an inspection.

How to Fix a Leaking AC

Fixing a leaking AC unit doesn’t always require major work, but it does require knowing what to look for. Start by checking the filter. If it’s dirty, replace it and see if that helps with airflow. If the unit is leaking again the next time you run it, the issue could be deeper, like a cracked drain pan or low refrigerant levels.

Our team at Wilson’s is trained to diagnose and repair these issues quickly, and we always start by identifying the root cause so you don’t just fix a symptom. If you had water buildup, damp smells, or pooling around your indoor unit this year, now’s the time to schedule a service before you need to rely on your system again.
