You should consider a central AC replacement if your unit is over 10 years old. While your air conditioner may last longer than ten years, the quality of your cooling will start to go down, and the price of your repairs will start to go up.

A professional air conditioning contractor can help you determine if you would benefit from a replacement. Get an expert opinion--Call NextGen Aire at 978-566-9601.

The average amount you will pay to have a central air conditioner installed will be anywhere from $3,000 - $7,000. Factors that can affect this price include:

  • Condition of your air ducts.
  • The type of system you are getting.
  • The HVAC contractor you choose.

Need a professional estimate on the cost? Contact NextGen Aire.

Your central air conditioner will let you know if it needs a refrigerant (Freon) recharge in a few different ways:

  1. Ice buildup on the outside of the unit.
  2. Hissing sounds.
  3. High electric bills.
  4. Uncomfortable indoor temperature.

Only a licensed HVAC contractor can handle refrigerant, so if you suspect a leak, contact the licensed pros at NextGen Aire.
