When To Replace Your Air Conditioner

When something goes wrong with your air conditioner, deciding whether it’s time to repair or replace it can be difficult. That’s why it’s important to pay attention to the signs. Indicators that it may be time for a full system replacement include:

  • Age: If your system is over 10 years old, it’s best to consider a replacement, as its energy efficiency is likely significantly reduced.
  • Frequency of repairs: Homeowners constantly calling for repairs may find that an AC replacement is a more cost-efficient way to get the cooling they need.
  • R-22 refrigerant: Older air conditioning units that use R-22 refrigerant should be replaced as R-22 causes environmental damage and is no longer readily available.
  • Efficiency: If your utility bills are constantly rising, it’s likely because your AC unit isn’t as efficient. The cost of replacement would be offset by savings on your energy bills.

Air Conditioning Installation FAQs

Professional air conditioning maintenance is critical to keeping your unit in top shape. We recommend scheduling an annual tune-up each spring for a thorough cleaning, testing, and inspection. By prioritizing professional maintenance, you can help extend the life of your system and improve its energy efficiency.

Our installation process starts with evaluating your home and comfort goals so that we can recommend the best AC system for your space. Once you’ve signed off, we’ll start by safely removing your old AC unit and preparing the area for the new system. We’ll then install the new air conditioner and turn it on to test and ensure proper performance.
