AC units are supposed to keep us comfortable in the summer heat, right? So, if your air conditioner isn’t blowing the way you’d like it to, what do you do?

Understanding the problem is one of the keys to solving it. Why is your AC not cooling upstairs? There could be a number of different factors at play.

That’s why we’ve put together this short and sweet guide. Find the top AC problems and how to correct them below.

Let’s dive in!

AC Dirty Filters

One common reason why your AC may not be cooling upstairs is a dirty air filter. The air filter in your AC system helps to remove dust, debris, and other pollutants from the air before they circulate throughout your home. When the air filter becomes dirty and clogged, it restricts the airflow and makes it difficult for your AC to cool the entire house evenly.

You can start by turning off your AC and replacing the dirty air filter with a new one as steps on how to make upstairs cooler. It is recommended to change the air filter every 1-3 months to ensure optimal functioning of your AC. Cleaning the vents and ducts in your home can also improve airflow and help to cool your upstairs more effectively.

Leaky Ductwork

There are several common reasons why your AC may not be cooling the upstairs of your home, with one of the most common being leaky ductwork. When there are holes or gaps in the ducts that carry cool air to the upper levels of your home, the cool air can leak out before reaching its intended destination. This can lead to uneven cooling and discomfort in certain areas of the home.

To combat this issue, regular AC maintenance is crucial. Check the ductwork for any visible damage or holes, and seal them with duct tape or mastic sealant.

Make sure that all registers and vents are fully open and not blocked by furniture or other obstacles. You can also try adjusting the dampers in your ductwork to redirect cooler air to the upstairs rooms. 

This also includes ensuring that the AC unit is properly sized for your home. Consult an HVAC professional to determine the appropriate size of the AC unit for this specific space.

Malfunctioning Thermostat

A malfunctioning thermostat is a common cause for an AC not cooling. This can be due to a variety of reasons such as a faulty sensor, incorrect programming, or electrical issues.

To start troubleshooting, check if the thermostat is set to the correct temperature and mode. If that doesn’t resolve the issue, try replacing the battery or cleaning the thermostat for proper functioning.

If the problem persists, it could be due to faulty wiring or mechanical issues, and in such cases, it’s best to call a professional for repair. Proper maintenance and regular servicing of the thermostat can also prevent future malfunctions and ensure efficient cooling.
