Improving the comfort of your Fresno area home could be as easy as installing a zoning system upgrade. In many cases, homeowners dissatisfied with home comfort are resigned to the idea that upgrading the HVAC equipment – whether furnace, A/C, boiler or heat pump – is the only solution to the problem. Before investing a large sum of money in a new system, talk to your HVAC contractor about a zoning system upgrade. A zoning system employs multiple thermostats for targeted indoor climate control, allowing home occupants to set temperatures in individual zones and saving energy by not providing heating or cooling to unoccupied areas.
