Deciding whether or not to replace your air conditioner isn’t easy. An AC is a big investment, so we know you want to be sure about your decision.

You can bet that we have the training, tools, and technology necessary to provide expert solutions and help you make the right choice for your home.

It is probably time to upgrade your AC if:

  • It is more than 15 years old
  • It requires frequent, costly repairs
  • Your energy bills are skyrocketing
  • It doesn’t adequately cool your home

If your system is less than 10 years old, chances are you do not need to replace it. A younger AC system can nearly always be fully repaired.

  • Improved indoor air quality: Preventative maintenance helps ensure that the air circulating in your home is as clean and healthy.
  • Reduced energy consumption: A well-maintained system runs at peak efficiency, meaning energy use will decrease substantially.
  • Improved comfort: A properly maintained system evenly distributes heated and cooled air, helping you to enjoy maximum comfort within your home.
  • Extended system lifespan: By keeping your system in top shape and preventing major breakdowns, the lifespan of your system can be extended by years.
