How An Air Conditioner Actually Works by Central Carolina Air Conditioning

Posted on: July 24th, 2016 by Derek Barmer No Comments

Did you know how an Air Conditioner unit actually works?

Obviously it keeps your home cool during the summer. But do you know how it actually works internally do this? DSC04885

Air conditioners move the air in two different directions- indoors and outdoors. In order to cool the air indoors, it operates as a dehumidifier by taking the humid air and reducing its volume causing it to release a portion of its moisture.  Hence the need for drains and pans near or attached to your air conditioning units.

The hotter the day, the harder your air conditioner unit has to operate to cool off the indoor temperature.  There are several major parts to your air conditioning unit that work together to cool off your home. Any of these parts can go out causing your air conditioning unit to stop working.

  1. Evaporator – Receives the liquid refrigerant
  2. Condenser – Facilitates heat transfer from one area to another
  3. Expansion valve – monitors refrigerant flow into the evaporator unit
  4. Compressor – A pump that pressurizes refrigerant

Oftentimes people believe they have to replace their entire air conditioner if it stops working.  We will discuss more how each of these parts work in unison to cool the air in your home.  But in the mean time, know that we are able to review all of these parts to see if only one of these components need replacing first.

The Great Anode Rod

Posted on: July 20th, 2016 by Derek Barmer No Comments

water heaterSo, you may have never heard of the anode rod in your water heater.  But it is working to save you money every day.  What is it?  This simple steel core wire, wrapped in another metal – usually magnesium, aluminum or zinc sits in your water heater and keeps it from rusting.

In order to understand how this works, you have to understand how rust works.  Corrosion is a natural process where metals are oxidized – oxygen molecules attach to the metal and cause it to deteriorate.  This is a result of electrolytes leaving one metal and attaching to another.

This process is continuous.  It goes on all the time without us taking much notice.  Anode rods are a way to counteract this process.  Anode rods ‘absorb’ the oxygen particles.  They are more active than the metals they are designed to protect and intercept those particles instead of the metals they are meant to protect.

Since it works in a protective fashion, it is important to replace those rods before they are exhausted.  If you don’t you expose yourself to risk for rust.  One way to do this is to inspect your anode rods each year.  Typically, you can expect to get five years out of your anode rods, but you should check every year as individual water quality determines rod length of life.

So, what material is best?  Magnesium is the most common, but it is not good for hard water.  Aluminum stand up to hard water but have been linked to common illnesses like Alzheimer’s disease.  Zinc rods are similar to aluminum but also contain zinc to counteract sulfur.

Getting Your Home Vacation Ready

Posted on: July 12th, 2016 by Derek Barmer No Comments

Are you planning a getaway this summer?  You’ve probably thought about what you need to pack, but have you thought about what vacationyou need to do in your home to get ready for vacation?   If you are like most, you likely haven’t given it much thought.  So, how do you get your home ready?

First, think about what you would do if you had a leak in your home. Of course, you would cut off the water at the main valve to prevent future damage.  You should do the same when you plan to leave for a time.  Cut the water off at the main valve before you leave so that if there is a leak it will not turn into a major headache.  Remember that this will impact your landscape watering and pool water maintenance.  Make arrangements to let your house sitter or landscaper to be able to turn the water on as needed to meet these needs. 

Next, think about ways to save money while you are on vacation.  Shut your ice maker off while you are away.  Why make ice when you aren’t even there?  Shut down any water softening systems to save even more.  Of course, your hot water heater is your biggest opportunity for saving. But cutting it off, you reduce most of your consumption.  Cut this off at the main breaker to prevent it from heating an empty tank and burning out.  Finally unplug any vampire appliances.  These include any appliances that have a clock and draw energy even when not in use.

How Much Does a Light Bulb Cost?

Posted on: July 8th, 2016 by Derek Barmer No Comments

blulbThe cost of purchasing a light bulb is easy to determine.  You simply look at the label on the shelf.  Pretty straightforward, right?  But there is a hidden cost that many consumers are less familiar with – the cost to operate that bulb and how often you have to replace it.  So, what does it cost to operate each kind of bulb? The Department of Energy provides information on what it costs to operate a light bulb with a 60 watt brightness (or the equivalent in non-incandescent light bulbs).  According to the Department of Energy, based on an energy cost of $0.11 per kilowatt hours (kWh):

  • A 60 watt incandescent that is used for 1,000 hours 60 KWh of electricity, for a total cost of $6.60.  This bulb will normally last for 1,000 hours.
  • A 43 watt halogen bulb will use about 25% less energy.  You can expect to spend about $4.73 to operate for 1,000 hours.  You can expect this bulb to last 1,000 to 3,000 hours.
  • A 15 watt compact fluorescent (CFL) light will cost $1.65 to operate for 1,000 hours and can last for 10,000 hours.
  • A 12 watt light-emitting diode (LED) light is the most efficient bulb on the market today.  At only $1.32 for 1,000 hours of operation, it costs 80% less to operate than the traditional incandescent bulb.  In addition, this bulb will last for up to 25,000 hours.

So, while LED and CFL light bulbs may appear expensive when you are shopping, they represent the best value in the long term, both in terms of costs to operate as well as the expected length of life of the bulb.

How to Keep Your Cool

Posted on: July 7th, 2016 by Derek Barmer No Comments
Now that the weather is heating up and the humidity is climbing, it is really starting to feel like summer here in the Triad of North Carolina.  So, we know your air conditioning is probably running by now cool_down_on_a_hot_summer_day_6472in order to keep your home cool and dehumidified.  But is there anything else you can do to keep your cool in all this heat? YES!  Here are a few tips to help make the most of your precious cool air!
  • Close blinds or curtains during the heat of the day – especially those windows that get the afternoon sun.  While it may seem like a small thing to do, the solar heat that enters your home from the exposure can easily add a few degrees to the temperature in your house.  So make your home a temporary movie theater for the hottest hours of the day.
  • Change your air conditioner filters often.  Dust can accumulate quickly in your home at anytime of the year, but during the summer you want to make sure your system is achieving maximum efficiency. 
  • Service your system as recommended.  This goes without saying, but preventative maintenance is the best value for your dollar.  Preventing failures is a lot less expensive than repairs.  If you purchase a maintenance plan you can also get discounts if repairs are needed. 
  • If you find that you have ‘hot spots’ in your home, rather than turning down the air conditioning call in a professional to balance your air conditioning and consider strategic use of fans to help circulate the air.
