Air Conditioner Tune-Up


Regular maintenance is essential for keeping your A/C running reliably all summer. A tune-up can help to identify and fix any potential problems before they cause major damage. This can save you money on repairs in the long run.


Benefits of Our A/C Tune-Up:

  • Lower the cost to cool your home
  • Extend the overall lifespan of your system
  • Avoid repairs by catching small problems
  • Improve indoor air quality

We include a Money-Back Guarantee on our A/C Tune-Ups—if your A/C system stops working for any reason after our cooling maintenance services, we’ll credit the cost of the tune-up towards repairs or refund your money, no questions asked!

Air Conditioner Replacement


Is your A/C more than 10 years old? If so, it may be time for a replacement. Old air conditioners are less energy-efficient, which means they can cost you more money on your energy bills. They also tend to break down more often, which can be a major inconvenience.


Other Signs It’s Time To Replace Your A/C:

  • A/C no longer keeps your home comfortable
  • A/C system requires frequent repairs
  • You want to increase your energy savings


If any of these signs apply to you, contact us today for a free in-home estimate: 800-642-4419. We’ll match you with an experienced Comfort Consultant who will assess your current system and learn more about your family’s comfort needs. We’ll also consider your budget and our financing options before providing you with multiple replacement options.
