Can I Replace Central ACs Capacitor myself?

One of the most often worn-out components in residential air conditioning systems is the capacitor. They normally last for several years, but if you keep the same air conditioner for longer than ten years, you'll need to replace them at least once.

A Plus Quality recommends avoiding any attempts to replace the capacitor yourself. The capacitor keeps a sizable charge even when you turn off the AC. If you touch it, you risk being electrocuted.

How do you know when a capacitor needs replacing?

Here are a few typical signs of a failing AC capacitor:

The AC isn't blowing cold air
One of the first indications of a problem that many homeowners see is an air conditioner that doesn't pump cold air. You should call in for expert assistance if the issue persists after turning your machine off and back on several times.

Exorbitantly high energy costs
The issue could be caused by an AC capacitor failing. The harder you make your air conditioning system work to complete the task, the more energy it will take.

A buzzing sound
As soon as your AC system starts up, please pay attention to it. Your capacitor may fail if your air conditioner makes a humming noise or starts slowly.

An outdated HVAC unit
For whatever cause, an old HVAC system will eventually quit functioning. If your appliance is more than a 10 years old and periodically refuses to switch on, the capacitor might need to be changed.

AC Shuts Off By Itself
Occasionally turning off on its own could signal that your capacitor is malfunctioning.

The AC Doesn't Turn On Right Away
Does your air conditioner occasionally take a while to switch on? This is another indication of a deteriorating or defective AC capacitor.

The AC Won't Start
A defective AC capacitor can cause your air conditioner's complete inability to start.

  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • What is a heat pump?

    Heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances.
