With temperatures expected to climb to the upper 90s on Saturday, now might be a good time to check your air conditioning unit. “We are looking at temps to be 90 to 98 for the Auburn area on Saturday” said Cynthia Palmer, meteorologist for the National Weather Service in Sacramento. On Sunday temperatures will be in the lower 90s, according to Palmer, but lower temps should arrive on Monday. “There will be a gradual decrease in temperatures starting Monday,” Palmer said. With energy costs rising, it could be beneficial to have your home or office cooling unit checked. Studies conducted by PG&E found that your home or office’s cooling system could lose 10 to 30-percent of its cooling capacity due to leaky ducts. PG&E recommends having a certified air conditioning company make repairs to any leaks, because special materials and approved procedures must be used. According to information that can be found on PG&E’s Web site, duct testing by a certified air conditioning company or contractor can determine by metering just how much cool air may be leaking from your system. Two areas where leaks may occur are the supply and return points on your unit. When asked about air conditioning efficiency, Elmer Partridge of Miller’s Heating, Air Conditioning and Sheet Metal, Inc., in Auburn, had this advice. “The best thing is to keep your air filter clean. If that gets blocked then your air efficiency goes way down,” Partridge said. When it comes to leaks, Partridge said, “It’s best to have that work done by technicians who know what materials to use.” In regard to metering tests that can be performed on your unit, Partridge said that Valley Ducting in Rocklin can perform those tests.
