Incorrect Thermostat Settings

It’s always worth double-checking your thermostat. It may be set to a higher temperature, programmed incorrectly, or not calibrated properly.

Dirty Air Filters

Airflow restrictions can significantly impact your AC’s ability to cool. A dirty filter is often the culprit and is one of the easiest things to rectify.

Refrigerant Issues

If your AC system is low on refrigerant, usually due to a leak, it won’t be able to reach cooler temperatures effectively. This is a job for a certified technician.

Outdoor Unit Obstructions

The outdoor unit needs clear airflow to release heat from your home. If it’s obstructed by debris or foliage, it can’t operate efficiently.

Ductwork Leaks

Leaky ducts can cause cool air to escape before it ever reaches your living spaces, resulting in higher indoor temperatures.

Overworked AC System

On extremely hot days, your AC might struggle to maintain temperatures below 74 degrees, especially if it’s not sized correctly for your space.

Mechanical Failures

Components within your AC system, such as the compressor or the evaporator coil, may be malfunctioning.

What Can You Do?

Before you call in the professionals, here are a few steps you can take:

Check and replace your thermostat batteries.

Clean or replace your air filters.

Inspect the outdoor unit and clear any blockages.

Ensure all vents and registers are open and unobstructed.
