Why Your AC Struggles in 90-Degree Weather

When it gets hotter than 90 degrees, your air conditioner has to work harder. You might notice it runs all day or takes longer to cool your home. This can be frustrating, but it doesn’t always mean your AC is broken. 

Most air conditioners make your home 15 to 20 degrees cooler than the outside. So, if it’s 95°F outside, a home temperature of around 75°F is normal. Before you call Golden Rule for service, try these simple tips. They can help your system cool better. 

Check Your Air Filter First 

A dirty air filter is a common reason why an AC struggles in hot weather. Dust, pet hair, and dirt can block airflow. This makes your AC work harder and cool less effectively. 

Check your air filter. If it’s dirty, replace it. In summer, check your filter every month. A clean filter helps your system breathe and can lower your energy bill. If changing the filter doesn’t help, Golden Rule can inspect your system. They will look for other problems. 

Make Sure Your Thermostat Is Set Correctly 

Sometimes, the issue isn’t with the AC but the thermostat. 

Make sure it’s set to Cool and the fan is on Auto. If your thermostat uses batteries, replace them if they’re low. For smart thermostats, make sure the schedule is still the same. 

If your home isn’t cooling, that’s a problem. Everything might seem fine, but it isn’t. Golden Rule can check your thermostat. 

Give Your Outdoor Unit Room to Breathe 

Your outdoor AC unit removes heat from your home. If leaves, weeds, or grass block it, the system can’t release heat as easily. 

Go outside and check around the unit. Clear away any plants or debris, leaving about two feet of space on all sides. If the unit is dirty, gently rinse it with a garden hose. Never use a pressure washer; it can damage the fins. 

Keep Extra Heat Out of Your Home 

Your AC must remove all heat that enters your home. Close blinds or curtains during the hottest part of the day. This helps keep your home cooler. Use the microwave or grill instead of the oven to reduce heat. Running the dishwasher at night helps. So does using the washing machine. 

These simple changes can reduce the load on your AC and help it keep up on hot days. 

Watch for Warning Signs 

If your AC blows warm air, leaks water, makes loud noises, or freezes up, call Golden Rule. Ice on the refrigerant line is another sign of trouble. Turn off the cooling and switch the fan to On while waiting for service. 

Fixing problems early helps. It can stop bigger repairs later. It also saves money. 

Why Annual Maintenance Matters 

Regular maintenance is the best way to help your AC handle Iowa’s hottest days. During an AC tune-up, a Golden Rule technician checks key parts. They test airflow and inspect electrical connections. They also look for worn components. 

Regular maintenance helps your system cool better. It can also lower energy costs and may extend its lifespan. It also gives you peace of mind before summer’s hottest days.
