Bethany Heating & Air Conditioning Services puts an emphasis on annual preventive maintenance. The precision tune-up specialist who maintains your equipment will thoroughly check it for safety and operational efficiency, tune it up for maximum fuel efficiency, and inspect it for potential faults.

This saves you money by reducing your fuel bill, by avoiding costly breakdowns, and by prolonging the life of your equipment.

Repair or Replace your Heat Pump, Furnace Heating or Air Conditioning System?

  • Your current air conditioner is more than 10 years old
  • Your equipment needs to be repaired every year
  • Your air conditioner is noisy
  • Some rooms in your home are too warm or too cold
  • Your home seems humid, which is caused by poor system operation or leaky ductwork
  • Your home gets dusty when you operate your air conditioner, which could also mean that your ductwork needs to be inspected and possibly sealed, or that your filter needs replacement
