1. Your AC cannot cool your home
Let us begin with the most apparent sign that your air conditioning unit requires some repairs, as it is not chilling the air inside your home. When you switch on your AC and do not notice that the air is blowing out of your registers or, in case the ducts do not get cooler as the day proceeds, it is a likely sign that your AC unit required some professional repairs. You might have a malfunctioning air conditioner if the air conditioner won’t turn on or the temperature inside your abode is not cooling down within a reasonable time. Your compressor may be malfunctioning, your Freon line might have a leak, or the power connections may have a short circuit. Whatever the reason, you should call your home warranty company or an air conditioner repair company immediately.
(It is a good idea to check the filter of your air conditioning unit to check if it needs replacement or cleaning, as that is the cheapest and easiest fix for an air conditioning unit that will not turn on.)
Your air conditioning unit needs to be looked at by a professional if you turn the unit on, but there is little or no airflow. A failed blower motor, a clog in the ducts, or a leak in your ductwork, can cause such a problem.
