How To Change Capacitors      

How many of you have been charged upwards of $200 for a capacitor? Those days are over a capacitor change out can be done in minutes and is one of the cheapest fixes for your AC.

The dual capacitor is what starts and runs the compressor and fan on the outdoor unit. When troubleshooting your machine for a bad capacitor you will probably notice there is air coming out of your vents but its not cold/hot and the outdoor unit is not turning on but making a slight humming noise.

Installation

Estimated Job Time: 10 min.

Tools And Equipment Needed: Drill or Nut Driver and Capacitor.

Difficulty: Easy

 

Turn Off The Power- Turn breakers and/or disconnect box off!      


                                                                                                                                                                                                                                                                                                                                                                                

Locate The Capacitor- Typically  found on side panel of outdoor unit where you see the electrical conduit connecting from the wall to your unit when bad it is usually swollen

 

Take A Picture-  Of the top and of the information sticker on the capacitor. Reasoning behind this is to know where the wires are connected so you can attach the new one appropriately as well as know the size you will need for replacement

Remove Capacitor-  Disconnect harness and wires

Order New Capacitor- Don’t get any  capacitor get the right size that is necessary. The size is measured in (uf) a common size is 45/5 .

Install New Capacitor- Install new capacitor wire for wire like the picture you took

 

Turn Power On- Restore power at breaker panel and/or disconnect box

UV Sterilization Systems (UV Lights) 

Ever been told your Air Handler or Furnace has mold, mildew, or microbial growth inside? Your AC company probably told you that you would need to spend anywhere from $500 to $1000 on a UV light installation. Before scratching a check to your technician allow me to shed some light on what UV sterilization systems are and how to install one yourself for a fraction of the cost .

What Does It Do?

UV systems are installed inside the indoor unit to kill microbial growth such as mold and mildew as well as sanitize the air that passes through. Your heating and cooling system circulates the air in your home on average 100 times per day. SHS (Sick Home Syndrome) kills upwards of 1 million per year so it is very important for you and your family to breath clean air.

How Does It Work?

The low micro watt economical unit is effective at killing germs and controlling allergens on surfaces that are irradiated. UV Systems use germicidal UVC to kill harmful bacteria, fungi, and viruses. The ultraviolet lamps reproduce natural germicidal rays that are not a chemical treatment but are deadly to micro-organisms that spread throughout your home. A properly installed UV System poses no threat to people, equipment, or indoor environment

Ordering UV System

UV systems are not sold at your local home improvement stores. In order to find the right UV system you must find the nearest HVAC part house that sells to the public or order online. Below I’ve listed Two different systems that I know work very well and are listed at a very competitive price point. Both UV systems come with a magnetic bracket to help easily install the lamp. The only difference between the two UV systems is the price and the bulb life span. The first system has a bulb life span of 1 year the latter has a lifespan of 2 years. ORDER NOW

Installation

 

Turn Off The Power- Turn breakers and/or disconnect box off!

 

Remove The Panels On Air Handler- Using a 5/16 or 1/4 nut driver depending on brand of unit take out between 4-10 screws to remove air handler panels.

 

Example of Air Handler with panels off

 

Locate Main power Line- This will be easy find the 2-3 wires coming into the side of the air handler. One wire will be black, one red, and occasionally one green(ground wire). The black and red wires will often be wired into bottom of the breaker inside the air handler.

 

 

Insert Wires- First, with a flat head screwdriver loosen red and black wires. Next insert the black and red wires from the UV kit in with their matching colors (red with red black with black). Then tighten screws and tug on wires to make sure they are all tight.

Grounding UV System- Find the green wire that is mounted by a brass or green screw. Then loosen screw then  insert green wire and tighten screw.

 

 

 

 Mounting UV Lamp- Attach lamp to magnetic bracket and find somewhere in the air handler to mount so that the UVC rays can reach the most surface area.

 

 

 

Put Air Handler Back Together- Screw panels on tight to avoid air leakage.

Restore Power- Turn power back on at the breaker panel and disconnect box and start reaping the benefits of hospital quality air !

*NOTE- UV lamps will need to be replaced after 1 or 2 years depending on which kit you purchased weather or not the lamp is still glowing.

Do not ever look at UV lamp without protective eye gear UVC rays will cause irreversible damage to you eyes.  

 

Hard Start Assist 

Does your compressor make a hellacious noise upon start-up?

Do your lights dim every time your unit turns on ?

Adding a Hard Start Assist to your system can erase those problems and add at least 3-5 years to the lifespan of your compressor. That’s not even the best part, the best part is you can install it yourself for under $50.

What is a Hard Start Assist?

A Hard Start Assist stores energy inside it’s capacitor and when the unit turns on it uses that energy to aid the compressor upon start-up. After start-up the Hard Start Assist then uses the power from the unit to recharge itself so it’s ready to help again on the next heating or cooling cycle.

                             

1-3 Ton Kit                                         3.5-5 Ton Kit

 

Installation

FAST and EASY! No experience needed.

Turn Off The Power- At the main breaker and disconnect box.

Open Electrical Panel- On the outdoor unit remove the screws to the electrical panel.

 

 

Attach Both Wires To Capacitor-Attach both wires to the capacitor. One wire to the HERM and one to the C (common). It does not matter which wire goes to which.

 

Mount Hardware- Attach the Hard Start kit with the screw and zip ties included in kit and put the panel back on.

 

Restore Power- Turn power back on at the breaker panel and disconnect box.

 

 

When you purchased your HVAC system weather or not you got a 5 year warranty or 10 year extended warranty there is one thing your AC company often forgets to tell you…..your manufacturers warranty does not cover LIGHTNING STRIKES OR POWER SURGES! So yes that means your precious AC equipment that you paid thousands of dollars for could be damaged as a result of a power surge and you will NOT be covered. Please note that even if you have a surge protection device through your power company it only covers the appliances inside your home. The outdoor AC unit also know as the condenser where the heart of your air conditioner (the compressor) is located resides outside of your home therefore is not covered. Surge protection is a must have for all heating and cooling systems young or old.

Selecting Your Surge Protection Kit

HVAC and electric companies mine included charge anywhere from 250-500 to install a surge protector. The step by step tutorial you are about to watch shows me installing a surge protector in under 5 minutes. The only thing you will need is a flat head screw driver and a surge protection kit. The Surge Kit i recommend is the ICM Protection Kit because the cover up to 10,000 in damages.

  1. It never ceases to amaze me what can be found on the internet. Need to know anything about anything at all, do a search and you’re bound to find out that someone has posted detailed information on it somewhere.

    Air conditioners are expensive to fix if you call in a refrigeration mechanic. Most of these tragedies cost the earth to do repairs and installs. Your how-to post here really shows just how simple it can be to change the capacitor in the outdoor air conditioning unit. Thank you. Exactly what I was looking for.

    1. Thanks for the comment Sir !

      When you said air conditioners are expensive to fix you weren’t lying I am often the guy that has to break the bad news to my customers on service calls. It means a lot to hear my tutorials are helping fellow homeowners I really appreciate the kind words. I am currently in the process of finishing another tutorial on installing your own UV Sterilization system in your unit I hope to see you check back soon

  2. Hi there, thanks for the tips on replacing the run capacitors. Those things are always going out right when the days are the hottest! makes me wish I had 3 phase electrical power. 3 phase motors don’t use capacitors.
    Surge protection is not a bad idea either. We get a lot of lightning strikes here, but never had a problem with any equipment getting damaged – yet.

    Cheers

    1. Hey Mr.Oren thanks for the comment ! Run capacitors failing is one of the most common problems here in FL I find myself changing anywhere from 50-100 of them every summer.
