Our local development is fairly recent, so they are continually expanding it. It has grown into a bigger and bigger project over the three years since we moved in. Watching the development has been a fascinating experience. I am interested in how different contracting companies built homes and businesses. They each seem to take different approaches to the way they do it. It’s helpful to see what brands of materials and designs are popular, plus how they age over the next few years. Some are obviously more reliable than others, and I can tell the ones that are of superior quality. One of the things I’ve learned is that it is becoming more and more common to install two separate cooling systems, especially in multiple story houses or commercial properties. The amount of electricity to operate two Air Conditioning units is less than if one larger unit was cycling all the time. The pair can be connected together and programmed to work in tandem with each other. However, you can program each of them to heat or cool as needed. One can provide heating while the other cools. You can even shut the upstairs off in the Winter. I live in an area of the country where the weather is warm for most of the year, so having that kind of control over the Heating plus Air Conditioning equipment is very cost-effective. The higher efficiency ratings of new heating and cooling products also helps to trim monthly utility bills. Superior insulation and window UV ratings keep new homes cooler in the Summer and warmer in the winter. Plus, we are able to reduce our carbon footprint as well.
