When should I install a Zoning System? If you are modifying your Salt Lake City area home air conditioner, furnace or heat pump, it is a good time to also install a new zoning system to fix hot and cold spots or special temperature needs in the home. When your new comfort equipment is matched with a zoning system, comfort is enhanced through customized temperature control in each zone. Zoning is also a great idea for new homes since the system can be installed during construction. If you are buying a new home, check with your builder about a zoning system. It could make the difference between just enjoying your new house and being truly comfortable in it.
