Last month we discussed some system areas that need to be checked when a customer has complaints of being too hot or too cold. Of course, first you must make sure that the entire system is working as it should, and that sufficient amounts of air are being delivered throughout the home's ductwork (if the home has ductwork), or that the hydronic system is circulating as designed.
Once you have done this, you can offer control solutions to help improve your customer's comfort, IAQ, and even energy consumption.
