Heating & Cooling
Heating and cooling account for a little more than half of the energy used in a typical Minnesota home. To keep those energy bills as low as possible, your heating and cooling systems should be inspected annually and maintained. Replace filters regularly and seal your heating and cooling ducts. A home energy assessment will also detect leaky ducts.
Consider replacing your furnace or boiler, for instance, if it’s nearing the end of its expected life (15-20 years for furnaces, 20-30 years for boilers), it requires expensive repairs, or it is inefficient. Look for the ENERGY STAR® label when shopping for heating and air-conditioning systems.
