Casteel Heating and Cooling

A heat pump is a two part system that handles the heating and cooling in your home. There is an air handler that is located inside your home and a unit that is located outside of your home. This is not unlike a central air conditioning system.

The difference is that a heat pump moves heat as opposed to generating heat. For instance, in the winter, a heat pump “moves” the heat from the outside to the inside. During the summer it does the opposite; it moves the heat from the inside to the outside. It is “pumping” the heat to the place you want it. At Casteel Heating and Cooling, we use Trane heat pumps. They have a SEER rating of up to 19.0 and are among the best value in the industry!

…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.

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.

I know, I know…it’s still cold outside and we’re talking about Spring cleaning. Believe it or not the official first day if Spring is March 20th and that’s only 38 days away! No need to panic…we have time to get ready and that’s why we’re talking about it now. Just like everything else that gets cleaned out in Spring cleaning so should your HVAC system.Spring cleaning, by Chiot's Run, on Flickr

“But I haven’t used my AC all Winter long.” In a central air system the heating and cooling shares the same ductwork so your ducts have been busy all season long and require cleaning. At Casteel Heating and Cooling we recommend you schedule a tune up for your system when the season changes form Winter to Spring. one of our experienced and professional technicians can come  perform a very comprehensive 25 point inspection. That’s one thing you can check off your Spring cleaning list!

Casteel Heating and CoolingAir conditioners come in many different sizes, whether they are window air conditioners or central air conditioners. These units should be sized to cool the area of your home you’re trying to cool with the most efficiency. So how do you do that? Well, by measuring the area of the area to be cooled, you’ll have a pretty good idea what size air conditioner is for you.

To calculate this, simply multiply the length times the width of the room or area to be cooled. Then, as a practical number, multiply that total times 25BTU. This allows ample cooling, whether it is a rainy, moist day or a hot, sunny, humid day. Let’s say the room is 12 feet wide by 15 feet long. That means 12×15=180 square feet. Take the 180 sq. ft. times 25 BTU per square foot and you get the minimum BTU air conditioner you should buy. That means 180×25=4500 BTU cooling capacity is needed.

You may ask if a smaller air conditioner will work or a larger one may be better? Here’s a thought about those questions. Smaller BTU units will continually run, just trying to keep up. This will increase your electric bill and it is unlikely the unit will be able to cool the area effectively.

An air conditioner too large can be overkill. To dispute the rumor that bigger is better, an air conditioner too large will cool more quickly, but that may impede the reason for running the air conditioner in the first place. You see, along with cooling the air, the air conditioner is also extracting moisture from the air (humidity) that makes all of us feel hot and sticky. Although the air may be cooler, if the unit doesn’t run long enough, the moisture cannot be extracted from the air properly. It would be like being outside camping on a cool, clammy, foggy night. You know the feeling when your skin is moist and you get goose bumps when cool air flows over it. Besides, an air conditioner too large will cycle on and off frequently.

Do your self a favor and measure the area of the home to be cooled, calculate your BTU needs and size the air conditioner properly. Your local appliance store or heating and cooling center can aid you in selecting the proper air conditioner size for your home. Remember, too little is never enough and too much of a good thing can be bad.

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.”

Spring is a traditional time to clean and repair your home after the long winter season. It is also the best time to have an HVAC (heating, ventilating and air conditioning) contractor perform an annual pre-summer inspection of your system. This will ensure that your cooling system will be working properly when the hot, humid summer weather arrives.

According to ENERGY STAR, a typical contractor maintenance check-up should include the following:

  • Check furnace system controls and thermostat. This will insure that the starting cycle is working properly so the unit keeps you comfortable when you are home and saves energy (and money) when you are away.
  • Tighten the electrical connections and lubricate all HVAC moving parts. Faulty electrical connections and lack of adequate lubrication can reduce the life of the unit components. An improperly operating system can also cost you in the increased amount of electricity you use.
  • Make sure the condensate drain is working properly. Not only can a plugged drain or pipe cause water damage, it can also affect the humidity levels in your home.
  • Clean the evaporator and air conditioning coils. Dirty coils can cost you money. They reduce the system’s ability to cool the home so it must operate longer, leading to higher energy bills. Longer operating times also reduce the system’s life and increase the amount of energy needed to operate.
  • Check air conditioner refrigerant level. Too much or too little refrigerant will affect system efficiency, increasing energy costs and system life.
  • Make sure blower components are properly adjusted. ENERGY STAR? guidelines indicate that airflow problems can reduce system efficiencies by up to 15 percent!
  • Change air filters on a regular basis. Dirty filters reduce system efficiency and increase costs.

Proper homeowner and professional maintenance will allow your system to do its job and save you money.
