If you have additional questions, call us at 770-565-5884 or reach us online.

…and why do I need one?

First of all, let me explain zoning. Zoning is something that allows you to cool or heat only those rooms that you choose. If there’s a room in your home that you only use occasionally or a room that gets used at certain times of the day, you can control the temperature and the times the room is at that temperature or another altogether.

Casteel Heating and Cooling

How does it work? It works not unlike setting timers on your lights. The system allows you to set different temperatures for different zones and uses dampers that open and closed based on your settings for each zone.

What products do we use? We use a Honeywell Zoning System. Honeywell has been using this same idea since 1945 and has developed the technology for today’s homes. Their systems can handle anywhere from two to 32 zones and controls every zone from one device.

What are the key features? It meets the American Lung Association® Health House® guidelines. Its energy efficient because you are not heating or cooling any areas unnecessarily and there’s a five year warranty.

When you’re too cold, you can’t sleep. You can’t think. Kids can’t study and Santa Claus is a distant dream. This is the situation for too many of Georgia’s families and elderly citizens this year.

According to the latest Georgia Department of Labor figures, our neighbors are struggling with a 42% increase in initial unemployment claims in Fulton County and a 67% increase in unemployment claims in Cobb County. Even before the recent unemployment crisis, 188,000 people lived below the poverty line and mortgage foreclosures were at record levels.

Furnace repairs are too expensive for some families

Heating system repairs quickly mount into the hundreds, possibly thousands of dollars —which is why for many deserving families, these repairs simply cost too much.

While there are numerous worthy organizations dedicated to helping low income families offset their monthly energy costs, Casteel Christmas is the only one that helps our needy neighbors in Cobb and Fulton counties get broken, or inefficient heating systems back online. These types of repairs are costly and require expert technicians. At Casteel Christmas, we have the talent and expertise to take on the challenge.

We are already making a Difference

In 2008, supported by a growing sponsorship base that includes Ironstone Bank, and, Casteel Heating & Cooling helped needy Cobb and Fulton residents by providing free furnace repair services valued at $100,000.

We believe that through added support and sponsorship, Casteel Christmas will have a long-lasting and meaningful effect on the community through the knock-on effect of goodwill and the difference they make in the lives they touch.

History of the program

Casteel Christmas is a nonprofit organization that came about as an expression of the commitment of the employees at Casteel Heating & Cooling to their community. For over 20 years, the people at Casteel have helped Georgia residents stay comfortable. In 2008, with our community distressed with record unemployment and mortgage foreclosures, we decided to help those in need the best way we knew how—by helping kids stay warm this Christmas through functional furnaces.

What sets us apart

Casteel Christmas is the ONLY program dedicated to helping people offset expensive heating equipment maintenance and repair.

Who we help

Casteel Christmas provides heating system repair and maintenance to legal Cobb and Fulton county residents whose annual income is 150% of the federal poverty guidelines, or who are facing imminent foreclosure on their homes.

How we help them

We have committed labor, talent and repairs valued at $100,000 to help needy and deserving people to get the furnace repairs they need. We are raising money from the community and our sponsors to help increase our ability to help. We also recruit talent from the community and provide a framework for contractors and technicians who want to give their time to this effort.

When it’s cold, we walk over and turn up the thermostat, and when it is hot, we walk over and turn on the air conditioner to cool us down. But, how does that little box on the wall actually control the temperature of our homes or offices?

A mechanical thermostat is actually a very simple device. It is basically a thermometer attached to a switch that turns on your heater, whether your heat source is natural gas or electricity. If you remove the cover of your thermostat, you will see the inner workings and get a better idea of how a thermostat works.

The top layer holds a mercury switch and a thermometer coil. The mercury switch is just a small vial filled with the liquid metal, mercury. Within this vial are three wires: one at the bottom of the vial; one at the left of the vial; and one at the right of the vial. As the temperature rises or cools, the vial of mercury gets tipped to the right or the left making the corresponding wire come into contact with the wire that runs along the bottom. If the mercury gets tipped to the left, a connection is made that creates a current that energizes a relay, which starts the heater and circulation fan. As the room heats up, the vial levels off and once that is in balance, the connection is broken causing the heater to turn off. If the mercury switch is tilted to the right, another relay causes the air conditioner to turn on.

Casteel Heating and CoolingWhat tips the vial in either direction is the thermometer coil that rests against the vial of mercury. The thermometer coil is constructed of a bi-metallic strip made of two different types of metal, usually copper and iron, which are bonded together. Because the different metals respond to heat at different levels, this strip contracts and expands causing the coil to curl up or uncurl as the temperature changes. This curling or uncurling motion tilts the mercury vial, which then signals the heating source to kick off or on. When you adjust the temperature knob on your thermostat, you are actually adjusting the tightness of the coil.

Beneath the top layer of your thermostat, you will see the circuit board, which houses the wires that actually lead to the circulation fan and heat source. The circuit board is connected to the mercury switch via a metal screw and wire, which “reads” the switch and turns on the appropriate heating or cooling device.

Newer on the market are digital thermostats. These thermostats differ from the mechanical thermostats in that they use a thermistor, a resistor whose electrical resistance changes with temperature. The microcontroller in a digital thermostat measures the resistance and converts that number to a temperature reading. Digital thermostats can save energy because they can be programmed to turn the heat or air conditioning off or on at preset times throughout the day. For example, you can set the air conditioning to come on an hour before you come home from work, or have the heater remain off during the hours while you work and then turn on an hour before you get back so your home is warm and cozy when you open the door.

A  recent column in the Washington Post said that Americans rely far too much on air-conditioning. Except for health reasons during severe heat waves, it said, we should open some windows, let kids play outside, get to know the neighbors and enjoy much lower energy bills, all while helping the environment. Could you live without air-conditioning?



JODI NIX, Beavercreek: “No, because I’m a middle-aged woman about to go through menopause, and I’d be grumpy.”



TRACY VOGEL, Bellbrook: “I hate air-conditioning, because I’m always cold. I’d rather have the windows open, even in the heat and humidity, and just turn on fans. As long as air is moving, I’m fine.”



BRANDON NELSON, Beavercreek: “Capital N-O. Mainly because no breeze runs through my apartment, only hot, steaming air. Air-conditioning is the only way I don’t sweat myself to sleep.”



JIM COPPERSMITH, Dayton: “No, I can’t. Once you’ve had it, you’re pretty much spoiled, and it’s hard to go back. And that’s what I do for a living — installing and repairing air-conditioning — so it pays my bills.”



BEN HAWS, Dayton: “I could live without it, but I work with a lot of seniors, and they have to have the air-conditioning for health reasons.”



JOANIE RAUCH, Bellbrook: “I couldn’t live without air-conditioning, but I do try to be a good steward. I can take heat, but not the humidity. When it’s humid, that’s when I turn the air-conditioner on.”

Replacing an outdated central air-conditioning unit not only will save you money on your energy bill, but it also will affect your tax bill. The government has increased a tax-credit program to encourage homeowners to invest in energy-saving products. Tax credits are a particularly valuable tax benefit, because they directly reduce your tax bill rather than merely being deducted from your income.

  • Step 1

    Review the energy-efficiency tax credit savings available. The American Recovery and Reinvestment Act of 2009 introduced energy-efficiency tax credits for 30 percent of the total cost to purchase an energy-efficient central air-conditioning unit. This tax credit allows 30 percent, with a maximum limit of $1,500, of an air-conditioning unit’s costs to be credited back to consumers via their federal tax returns. For example, a unit that costs $3,000 will be eligible for a $900 tax credit. Any unit exceeding $5,000 is subject to the maximum eligible credit of $1,500.

  • Step 2

    Look for specific energy-efficient models when selecting a new air-conditioning unit. The U.S. government has specific standards an energy-efficient air-conditioning unit must meet to quality for a tax credit (see Resources). Different requirements are mandated in either a split or package air-conditioning system. Split-system central air-conditioning units must have an Energy Efficiency Ratio (EER) greater than 13 and a Seasonal Energy Efficiency Ratio (SEER) greater than 16. Package central air-conditioning systems must have an EER greater than 12 and a SEER greater than 14.

  • Step 3

    Buy and install your new energy-efficient central air-conditioning system and save all your receipts.

  • Step 4

    Save the manufacturer’s certification statement from your energy-efficient central air-conditioning system. This certification should be included with your purchase. The Internal Revenue Service will not require the certification to be filed with the taxes, but it does recommend keeping the certificate with your tax records. The certificate proves that you have purchased the correct product to qualify for the energy-efficiency tax credit.

  • Step 5

    File for a tax credit by including the proper forms with your federal tax return

    Usually, we’re sharing HVAC tips with you or showing you what certifications are necessary to find a qualified HVAC technician. Today we’re going to share something a little bit different!

    Hopefully, you’ve been following us and know how important our community is to us. Since it’s summer now and the kids are out of school, families are out an playing and vacation season is upon us, we thought it would be good to share some heat/ sun safety tips with you!

    Red Cross Heat Safety Tips:

    • Dress for the heat. Wear lightweight, light-colored clothing. Light colors will reflect away some of the sun’s energy. It is also a good idea to wear hats or to use an umbrella.
    • Drink water. Carry water or juice with you and drink continuously even if you do not feel thirsty. Avoid alcohol and caffeine, which dehydrate the body. Avoid using salt tablets unless directed to do so by a physician.
    • Eat small meals and eat more often. Avoid high-protein foods, which increase metabolic heat.
    • Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4 and 7 a.m.
    • Stay indoors when possible. If air-conditioning is not available, stay on the lowest floor out of the sunshine.  Remember that electric fans do not cool, they simply circulate the air.
    • Be a good neighbor. During heat waves, check in on elderly residents in your neighborhood and those who do not have air conditioning.
    • Learn Red Cross first aid and CPR.
