Why invest in regular tune-ups?

When you invest in annual tune-ups, you benefit from:

  • Lower monthly utility bills. Heating and cooling tune-ups keep your systems more efficient, which lowers the amount of energy they need to run and reduces your energy costs.
  • Higher comfort levels. When your HVAC system is properly maintained, it can more precisely hit any temperature you want as well as provide proper dehumidification in the summer.
  • Increased system lifespan. Systems that are annually maintained typically live longer than those that are neglected.
  • Lowered risk of repairs/breakdowns. During a tune-up, we'll identify and fix small issues before they lead to major repairs and/or breakdowns
  • Keeping your manufacturer's warranty valid. Most manufacturers will automatically void your warranty if you can't prove that you've had your system regularly maintained by a professional.
