Benefits of Installing Ductless HVAC

Ductless AC and ductless heating systems utilize several indoor air handling units to provide maximum performance and flexibility. By installing a ductless HVAC system in your home, you can enjoy:

  • Zone heating and cooling: By strategically installing air handlers in certain areas of your home, you can independently heat and cool zones to ensure each room is the perfect temperature.
  • Energy efficiency: With a zone system, you don’t have to waste energy heating or cooling areas of your home that you aren’t using.
  • Ductless operation: Unlike furnaces or central AC, mini-splits do not require ducts to blow heated or cooled air throughout your home, making them an ideal choice for older homes without ductwork.
  • Improved air quality: Ductless HVAC systems can also remove excess humidity from your home, giving you fresher air and increased overall comfort.
  • Space-saving design: With these systems, there’s no large piece of equipment taking up precious space in your basement or attic the way a traditional HVAC system might.

When To Replace Your Ductless Mini-Splits

The average lifespan of a ductless AC system is 10 to 15 years when properly maintained. As your system ages, you will start to see signs that it may be time to consider a replacement, including:

  • Frequent and costly repairs
  • Refrigerant leaks
  • Condensate line leaks
  • Decreased performance
  • Increased electrical bills
  • Rattling, grinding, or hissing noises

Ductless HVAC Installation FAQs

Ductless mini-splits have two main parts: the indoor unit, also known as the air handler, and the outdoor unit, also known as the condenser unit. When installing mini-splits, you’ll have one condenser unit and an air handler in each zone that you want to heat or cool. One condenser unit can typically support eight air handlers.

The best way to prolong the lifespan of your mini-splits is to schedule regular maintenance with a professional. Additionally, you can perform some DIY maintenance tasks, like changing air filters. You should also schedule any needed repairs promptly so that the issue doesn’t worsen and cause more problems.
