Become a Member of Our Peak Performance Maintenance Agreement!

One of the best ways to protect the HVAC system in your home is with a maintenance plan from GAC Services. Think of your heating and cooling system as a car—you wouldn’t drive 50,000 miles without an oil change, so why delay servicing your HVAC equipment any longer than you have to? When you choose to enroll in our Peak Performance Maintenance Agreement, you receive:

  • 20% off repairs – If by chance your HVAC system does break down, you’ll receive 20 percent off the repair
  • Priority service – Your calls automatically move to the top of our service list
  • Seasonal tune-ups – We will tune-up your HVAC system to ensure it operates at maximum efficiency and reduce the chance of mid-season breakdowns
  • Reduced Diagnostic Fee – Maintenance agreement customers receive a reduced diagnostic fee
  • 10% off electrical services – Members can take advantage of our experienced electricians at a discounted rate
