Duct, furnace cleaning & sanitizing service
Answer from pro:
HVAC systems require regular maintenance, much like a car. Ten years of experience in the trade urge me recommend the following maintenance schedule: duct cleaning - 3 to 4 years; furnace and AC cleaning - 2 years; humidifier evaporator pads - once/year. The indoor home environment is also important...children, pets, parties, carpeting, unpainted/unfinished basement floors and type of filter in the furnace. These conditions may decrease time duration between services.
