Heating System Repair, Maintenance & Installation You Can Trust

Q: How often should I have my equipment serviced?

A: Heating and Air Conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring. Oil-fired equipment should definitely be cleaned and serviced annually; at the beginning of each heating season.

Benefits include:

  • Discover potential problems and fix them quickly
  • Increase dependability of equipment
  • Provide maximum efficiency of equipment which lowers energy costs
  • Prolong the life-span of the equipment
  • Maintain safe and healthy operation of equipment
  • Drastically reduce the chance of a break-down which often occurs at night or on weekends when service rates are higher
  • May help to protect the environment
Q: How often should I change my filter?

 

A: It is important to change your filters regularly because dirty filters restrict air flow, reduce efficiency, and in some cases can cause your evaporator to freeze up. Disposable fiberglass filters should be replaced monthly, media style filters should be replaced every 4-6 months, and electrostatic or electronic filters need to be washed every 1-2 months.

Like most anything you own, you will find that regular maintenance is far less costly than repairs or even replacement later.
