When your air conditioner won’t turn on during a heatwave, it’s more than just inconvenient — it can quickly turn your home into an uncomfortable, even unsafe space. Before you panic or schedule a service call, there are a few simple things you can check yourself. These quick troubleshooting steps might save you time, money, and the stress of a sweltering home.
Inspect the Thermostat Settings
Start by checking your thermostat. Someone may have accidentally changed the setting from “cool” to “off” or “heat,” preventing the AC from starting. Also, make sure the set temperature is below the current room temperature. If your thermostat uses batteries, try replacing them — a dead battery could be the root of the problem.
If you have a smart thermostat, double-check the settings through the app and make sure it’s connected to Wi-Fi and receiving power.
Change the Air Filter
A clogged air filter can block airflow and prevent your system from running properly. In some cases, it can even cause the AC to shut down entirely. Replacing or cleaning the filter is an easy fix that can restore cooling performance and improve your indoor air quality.
