Is it Time to Replace the AC Condenser?

As February rolls on, Texas weather will continue to fluctuate but ease into warmer temperatures. As the warmer conditions hit, you will want to start cranking on the air conditioner for relief from the heat. If your ac unit appears to not be functioning correctly, you may need to replace the ac condenser. Contact Expert Air today for a professional evaluation and solution that is best fitting your needs.

Purpose of the AC Condenser

This vital part takes the gas created from the air conditioner and converts it to a liquid form by cooling it down. The liquid version creates the refrigerant that your ac system needs to function properly. If this crucial part malfunctions, the entire AC system will malfunction. Ignoring this issue can lead to very expensive replacement.

Causes of a Malfunctioning AC Condenser

  1. Blockage or leak
    1. Faulty tubes or seals will cause leaks
    2. Can occur over time or from a puncture or rupture
    3. Blockage from external debris but most likely from metal particles flaking off the condenser itself
    4. Blockage occurs usually from age or poor maintenance
  2. Dirty components and/or bad run capacitor
    1. Outside elements like grass can dirty your components. Clean the area surrounding your ac unit regularly to avoid this
  3. Faulty control board
    1. The control center of all component communication. When this is bad, the system won’t work correctly
  4. Motor has been burned
    1. Occurs gradually and is usually caused by stress on the unit and/or poor maintenance
  5. Blockage can mean multiple surrounding AC components will also need to be replace
  6. Have your AC system inspection by the professional technicians at Expert Air

Repair or Replace

  1. Repair if it’s a dirty condenser, bad run capacitor, bad switch, faulty control board, or burnt motor
  2. Replace when there are leaks, blockage, or the system age. Because ac systems have advances in technology every few years, sometimes it is more cost effective to replace with a newer model over repairing the current one.
  3. Have the professionals at Expert Air evaluate to determine the true extent of damage and the most advisable route

AC Capacitors Not Working & What It Means

For the ultimate comfort today, we rely heavily on electrical systems and electricity. Reliable electricity is required but your systems must be functioning correctly to be effective. When your capacitor goes out in your ac system, you aren’t feeling that beautiful breeze. Your air conditioning system is as complex as a car in that many components work in conjunction. From the smallest of issues to major haywire conditions, contact the professionals at Expert Air to repair or replace your ac units.

A major component of your air conditioning unit is the capacitor. They are so crucial, that without them, the motors connected to the fans and compressor wouldn’t work. Without getting thorough training on all the intricate details of the product, here’s an abbreviated lesson on Capacitors.

What Are Capacitors?

  1. They are small components that store energy.
  2. Attached to motors, they send a jolt of energy to kick start the motor
  3. They also send a series of jolts to the motor to keep it running
  4. The AC has 3 motors: Compressor, Blower, and Outside Fan
  5. Your capacitors energize them all

Why Failing Capacitors Matter…

  1. Regular wear and tear is inevitable in all parts, and over time the capacitors will lose their charge
  2. The beginning failure is notable by the “clicking sound”
  3. Call Expert Air for repair at this stage, before one of those 3 motors goes out completely
  4. “Humming Sound” indicates run/start capacitor(s) has gone out
  5. Repair before entire system goes out and requires replacement over repair
  6. “Hard Starting” means the compressor motor has gone out
  7. “Hard Starting” is when the AC struggles to start then shuts off shortly after. This is extreme strain on the system. Immediate professional assistance needed.

Replacing capacitors is not a do-it-yourself job, for the oil that can spill from the system is dangerous to handle. Contact Expert Air today to schedule your repair or replacement. Remember, regular maintenance will often help in avoiding majoring repairs and replacements. Expert Air has a great maintenance program that saves you money, time, and worries.
