Why Did My Air Conditioner Stop Working?

Why Did My Air Conditioner Stop Working?

It’s amazing to believe that in the mid-1960s, home air conditioning was considered such a luxury that just 10% of American households had it. Some Southern families slept on their porches to cope with the summer heat. Due to the presence of technology, many air conditioners are part of AI-powered processes. 

You expect your air conditioner to function flawlessly every time you switch it on; after all, it is your year-round friend. It is recommended to frequently get your AC service in Thornton, CO.

There are various reasons why your air conditioner won’t turn on, ranging from maintenance difficulties to your unit’s age. 

Reasons Why Air-conditioners Stop Frequently

Mechanical Issues

With the help of a chemical called refrigerant, an air conditioner’s purpose is to remove heat from your home and bring in cool air. 

There are two elements to an air conditioning unit: one inside your home and one outside. Air is blown through the chilled evaporator coil by a fan in the interior unit, which cools your home through air ducts. Outside, the compressor, condenser coil, and another fan expel the hot air that the refrigerant has released. 

Mechanical failure can occur in any of these components. If your fan’s motor fails, the outdoor unit will not be able to remove the heat. If your compressor is damaged, the refrigerant cannot move between the inner and outside units. If your AC is still new, you can consider getting an AC replacement in Thornton, CO.

A malfunction of Thermostat Batteries

Your air conditioner has suddenly quit working. You become panicked and begin calling various air conditioning specialists.

Have you checked the temperature on your thermostat?

A faulty thermostat can harm the performance of your air conditioner.

First, make sure your thermostat’s display is turned on. It can’t tell the AC to turn on if it’s turned off. Second, if you have a battery-operated thermostat, make sure the batteries are charged.

If your air conditioner still won’t turn on, switch off the thermostat and remove the cover to inspect the components. Examine the area for any debris or corrosion. Check for blown fuses; they might sometimes be the source of the problem. You can clear away the debris with a gentle brush, but corrosion difficulties will require the assistance of a specialist.

Clogged Air Filters

When was the last time you cleaned your air conditioner’s air filters?

If you answered no, you have a serious concern. Cleaning the filters is necessary regardless of the air conditioner you have.

The purpose of the filters is to keep the air flowing properly. If they are clogged with debris, ventilation is effectively obstructed. In this instance, your system will have to work harder to cool your home, and it may eventually fail.

Your AC evaporator coil is located in the interior unit, while the compressor is located in the outdoor unit. The refrigerant line connects these two parts. As it cools, any moisture on the coils freezes.

As the ice on the coils will melt, appropriately collect the water. Allow the filters to dry completely before turning on the air conditioner after cleaning.


To prevent the above-mentioned problems, ensure your HVAC system is serviced regularly. 

A thorough inspection and tune-up should reveal any issues before they become major issues.
