A home's heating system needs to breathe to run efficiently. Be sure to change the necessary filters regularly to keep the system up and running. Buying filters in multi-packs is a good way to ensure one is on hand when needed. Schedule an annual visit with an HVAC technician to service a home's heating system. This will help ensure equipment will last a long time and will be running efficiently throughout the heating season.
If you have duct work under your home, ensure that it is sealed, insulated, and not leaking precious hot air to the great outdoors. In a manufactured home, the crossover ducts can easily be disconnected or damaged. PUD's duct sealing program may be able to help. Call (360) 426-0777.
