When your AC stops cooling, it can turn a comfortable home into a nightmare. Understanding the root causes of AC cooling loss and knowing what steps to take can help you regain your comfort quickly and efficiently. All-Star Heating and Air Conditioning explores the common reasons behind sudden AC cooling failures and when it's time to reach out for AC repair in Knoxville, TN.

Common Causes of Sudden AC Cooling Loss

Several things could cause your air conditioner to stop cooling on its own. Knowing these reasons can help you figure out what's wrong and when you need to call for AC repair in Knoxville. 

Thermostat Issues

Your thermostat acts as the control hub for your AC system. When it doesn't work right, your home won't cool as it should. Look into these thermostat issues:

• Wrong settings: Make sure your thermostat is set to "cool" and that the temperature you want is below the current room temperature.
• No power: See if the display lights up. If it doesn't, try putting in new batteries.
• Dust and grime: Dirt on the parts can interfere with their function. Clean them using canned air or a soft brush.
• Set up wrong: If the thermostat isn't straight, it might read temperatures incorrectly. Use a level to fix it if necessary.

Electrical Problems

Electrical problems can make your AC stop cooling out of nowhere. Here are some common electrical issues:

• Tripped circuit breakers: Look at your electrical panel for tripped breakers and reset them if necessary.
• Bad wiring: Wires that are loose, not connected, or damaged can stop your AC from starting up.
• Fuses that blow: Check and swap out any blown fuses in your AC unit.
• Faulty capacitorsThese parts control the flow of electricity to the motors. If they break down, your AC might not work.

Refrigerant Leaks

Refrigerant plays a key role in cooling your home. When refrigerant levels drop because of leaks, it can lead to several issues:

• Poor cooling: Your AC won't cool as well as it should.
• Ice on evaporator coils: Not enough refrigerant can make ice form on the coils.
• Higher power bills: Your system has to work harder using more electricity.
• Health dangers: Leaking refrigerant can hurt you if you breathe it in, causing headaches and trouble breathing.

If you have a refrigerant leak, call All-Star Heating and Air Conditioning for expert AC repair service in Knoxville.
