Q: What if I don't want to give my credit card over the Internet?

A: That's fine, we don't want you to invest in our calculations until we are certain that we can help you. This means that we want you to contact us and share information about your home comfort system. Then once we are certain that we have the right solution for you, you can pay credit card over the phone through us. If you don't want to use your credit card and you aren't in a hurry, you can send a personal check, as long as we can withhold our calculations until the check clears.


​Q: How can these calculations alone, improve my comfort and save me money?

A: The truth is that they can't. This is an applied science. However, qualified heating and cooling contractors can use the information from our Multi-Zone or room by room calculations like a map to alleviate comfort problems. Through use of thermostats, an anemometer, and manufacturers free air space data, they can determine how much heating or cooling is coming to a certain area relative to how much is needed. Similar procedures can be used for hot water, steam, and electric resistance forms of heat. Once they know these things, they can tell you what needs to be done at a fair and certain price. This works for you because you are not subject to the expensive trial and error "let's try this approach". Once comfort is improved, and there is more balanced comfort in the house, people frequently experience energy savings.
