When is the Best Time to Replace your AC Unit in Phoenix, Arizona

It is perfectly normal for your AC System to make certain sounds such as the continuous humming noise while it’s running.

However, when you begin to hear strange/unfamiliar noises emanating from your outdoor AC unit, this could be an indication that something is really wrong. In such cases, it would be wise to contact a licensed and well-qualified HVAC contractor immediately.

So, let’s begin to with our list of AC noises that should concern you.

Screeching/Squealing

Over time, and with greater and greater usage, your AC system will tend to exhibit more noises. When an AC system starts squealing or screeching, this can be a sign of a part such as a belt or  ball bearing is worn out and in need of replacement or has become misaligned. When this happens, it’s best to call a professional HVAC repair company to properly diagnose and fix your AC unit’s issue.

Metal against Metal

If ever you hear the sound of metal scraping or otherwise rubbing against metal in your AC system, it’s recommended that you immediately shut off your AC.

There are any number of reasons why this could be happening, but it’s likely to be a serious problem that needs to be addressed quickly to avoid any hazard and/or an even more costly repair bill.
