What Is A Surge Protector?

We hear people talk about Surge Protectors, but do we know what they are?  More importantly what does a Surge Protector have to do with our Air Conditioning Systems and is it something you need to know about to stay cool this summer?

What Is Surge?

Surge is high amplitude, short duration electrical fluctuation which can cause harm to electric, electromechanical and electronic equipment, basically anything connected to the electrical box in your home.  Surge can be caused by lightning and storms, power outages, large appliances kicking on and other natural phenomena.

A Surge Protector Is

A box or unit designed to provide consistent power flow to anything electrical including your Air Conditioning System  even in the event of incoming surges, bounce surges from in rush current, outdoor moisture conduction from local lightening, or transient surges which are most common caused by other major appliances and electrical devices in our homes.

Different Types Of Surge Protection for A/C Systems

There are whole house surge protectors, which cover everything electrical in general.  However, this does not protect everything sufficiently and especially in regards to the one primary electrical unit placed outside in the elements, separate from the home itself, your Air Conditioning System.  There are specific Surge Protectors that can be installed at the Air Conditioner to protect the largest electrical unit at your home, well worth considering if staying cool in the hot summers in the valley of the sun is on your list of things that are important.

Why A Surge Protector just for Your Air Conditioning System?

The Air Conditioning Unit is outside in the elements it is more prone to and has an increased probability of being affected by storms.  In addition the A/C Unit pulls such a large pull as it starts up it is more likely to not only cause surges but more likely to be adversely affected by surges.   Surge Protectors installed specifically for the Air Conditioning System protects it from electrical surges caused by lightening, outages, hurricanes and any other natural events.

Insurance/Assurance, Are You Protected? 

Do you have a whole home surge protection?  If not, you are leaving every electrical, electromagnetic and electronic device in your home at risk of being destroyed by surge.  Do you have an Air conditioner specific Surge Protector?  If not, your greatest asset during the summer months at risk of being put out of commission and leaving you and your family and business sweating and running elsewhere to be safe from the sweltering heat of the Arizona Desert.

Enjoying the Assurance Plan

Insurance only protects you in the event something went wrong and you need to have it fixed.  Assurance is the protection that prevents anything going wrong in the first place.  Invest in surge protection and invest in peace of mind, the best plan you can have in regards to your Air Conditioning Units in Phoenix in the valley of the sun.

The Importance of the Run Capacitor

Run Capacitors for your A/C System

      Keeping you informed and educated about the little things that make all of the difference for your Phoenix Air Conditioning Unit is the best way we know to keep you cool and comfortable through the extreme heat of our long summer months.  Knowledge can equal peace of mind.

What is a Run Capacitor?

      A capacitor or condenser as it is sometimes referred to, is commonly used in electronic devices.  It is a combination of three objects, a pair of conductors for sending electricity and a dielectric which is some form of non conductive materials.  An electrical field is created between the two conductors which then stores energy.  This stored energy is used to boost current needed to maintain a charge during constant use of a motor as in your Air Conditioning Unit. 

In the case of the typical Air Conditioning Unit there are dual capacitors, one for the fan motor and the other for the compressor motor. The run capacitor is for the fan motor and the one for the compressor is called the start capacitor.  The Run Capacitor maintains a relatively constant voltage supply for the purpose of increasing the torque of the fan motor on start up.

When Should I check my Run Capacitor?

      If a run capacitor is not working or is not the right size for your unit it does not always shut your system down.  Rather, it throws off the magnetic field, causing the fan motor to run unevenly increasing energy noise and decreasing efficiency with a possibility of causing overheating problems and other performance issues.   The best clues will be the sluggish running of the fan motor or slow start up of the fan motor, with noises you may not have heard previously.  In extreme cases the fan motor will just not start up, so always consider the run capacitor when a fan motor is not working.

 

Do It Yourself or Call A Professional

 

      A multi-meter is required for capacitor testing.  If you are comfortable with the use of a multi-meter you may consider testing it yourself, there are always good instructional articles and videos on the internet.  However if you are not comfortable with using a multi-meter devise it is best to call a A/C Professional in Phoenix. 

Replacement of The Run Capacitor

 

        The Run Capacitor can be quickly diagnosed by a professional and replacement is equally fast, your Air Conditioning Technician can ensure the proper size Run Capacitor is installed providing a smooth running fan that starts up the first time every time.  A run capacitor is not something that is usually diagnosed during routine maintenance.  It does not gradually go out; it is either working or not working.  So if you feel your fan is not working to full capacity or hear it struggle on start up, call your Air Care Cooling & Heating LLC Professional right away.  This quick fix will keep your system running well and keeping you and your space cool.
