Cooling and Heating
Our friend told us that he needs his HVAC filter changed. He said it has been few months since the last time he did it. Upon hearing him, we also realized that we haven't changed ours yet since we moved in to our house mid of last year. I talked to hubby and he said that his friend who is HVAC engineer told him that HAVC filter should be changed every month if possible so it will function fully. I think it is just reasonable to do it every month since it is not expensive at all. A clean filter helps the furnace function efficiently; thereby, saving money for heating and cooling.
