Frequently Asked Questions

  • How long will my AC unit last?
    The typical life span for most air conditioners, heat pumps, or ductless AC systems is 12 to 15 years. To get the most life out of your system, change the air filter often, keep the area around the condenser unit clean, and schedule AC maintenance at least once a year.
  • Why is my AC leaking water?
    In most cases, water leaks are caused by algae clogging the condensate drain, though sometimes a thawing evaporator can also cause water leaks. It is best to have a professional inspect the condensate drain and drip tray for problems.
  • Why is my AC freezing up?
    Ice or frost buildups on the evaporator and refrigerant lines can be caused by a clogged air filter, airflow issues, dirty coils, low refrigerant, or compressor problems. Have the system inspected by an HVAC professional to be sure of the cause.
  • How often should I check the air filter?
    It is a good idea to check the air filter every month, replacing it whenever it looks dirty or clogged. Basic fiberglass or pleated filters can last one to three months, while high-efficiency or HEPA filters can last six months to a year.
  • When should I replace my AC unit?
    If your air conditioner is over 12 years old and is starting to have problems like frequent breakdowns, efficiency losses, or a major component failure, such as the compressor, it may be time for an AC replacement. If it is under 12 years old and has no major problems, AC repairs may be more cost-effective.
  • Does David Gray service rental properties and Airbnbs?
    Yes! The David Gray team is proud to partner with many property managers and short-term rentals throughout the area to ensure their property’s AC is operating at peak efficiency during their guest’s stays. Whether you need to prepare your AC system for the summer months or you’re looking to outfit your rental home for increased AC efficiency, we will provide the trustworthy AC services you need.
