Are you taking good care of your heating system? Without regular, professional maintenance, performance steadily diminishes.

Minor issues left unresolved quickly turn into more expensive repairs. Guardian Heating & Cooling Service offers proactive services to achieve superior efficiency, reliability and longevity.

When Should I Change My Filter?

Filter changes are extremely important. The filter helps to protect the system from dust and other debris that builds up on equipment, hindering performance and reducing efficiency. You can also lessen demands on the heating system by tightening up the house. Make sure windows and exterior doors are securely closed and sealed tight. Check for cracks and crevices where heated air can leak out and drafts come in. Insulation, caulking and weatherstripping quickly pay for themselves!
Make an effort to lower the thermostat setting when you’re away from home or heading to bed for the night. Even small adjustments make a big difference. If you’re struggling to remember or reluctant to return home to chilly conditions, take a look at the convenience of a smart thermostat. Intuitive controls automatically adjust to your schedule, taking advantage of energy saving opportunities and providing maintenance alerts!
