Have you ever struggled to get comfortable at home during a scorcher of a day? This can be even more troublesome if your AC unit isn’t working properly or needs maintenance. Even if you’ve called an HVAC professional for help, it’s important to take certain measures to help you out until they can service your home system. Here are seven helpful tips to help you stay cool during the summer heat.

Tip #1: Replace or Clean Your Air Filter Regularly

A clean air filter is the first line of defense against poor airflow and reduced efficiency. Most filters should be replaced every three months, but during peak summer months, you should check them monthly. Reusable filters should be washed thoroughly to remove dust and debris.

Tip #2: Seal Windows & Doors

Prevent cool air from escaping by checking for gaps around windows and doors. Weatherstripping and caulking can make a noticeable difference in energy efficiency, helping your home stay cool without overworking your system.

Tip #3: Keep Airflow Clear Indoors

Try to ensure your vents aren’t blocked by furniture or curtains. Proper airflow allows your system to distribute cool air evenly and prevents overworking any one component. Moving things around your living space can make a major difference in the efficiency of your HVAC unit.

Tip #4: Get Rid of Heat Sources

You can use curtains or blinds to block direct sunlight, keeping your home cooler overall. Try to also avoid using heat-generating appliances during peak hours. Even small changes can reduce the load on your AC system. You might even use your fan more often so that you don’t have to rely so heavily on your HVAC.

Tip #5: Keep Your Outdoor Unit Clean & Shaded

Debris, leaves, and dirt can often block airflow and minimize proficiency. Be sure to clean the area around your AC unit and gently wash the coils if possible. Also, providing shade without blocking airflow can help your AC work more efficiently.

Tip #6: Use Your Thermostat Wisely

Set your thermostat to 78°F when at home and slightly higher when you’re away for several hours. Programmable or smart thermostats can even allow you to create schedules; that way, your home cools only when needed, saving you energy and money!

Tip #7: Consider a Maintenance Plan

Of course, having routine annual maintenance on your HVAC can ensure your system remains in great condition in the long run. Regular professional care extends the life of your AC and reduces unexpected breakdowns during the hottest months. And if your system unit is nearing its lifespan, it’s always best to replace it with a new one for optimal function.

By following these tips, you can keep your AC running efficiently, save on energy bills, and enjoy a cool, comfortable summer.
