Mini-Split

Why mini-split systems are different

• Ductless design: eliminates energy loss from leaky ductwork.
  
  
• Zoned comfort: set different temperatures in different rooms.
  
  
• Compact installation: ideal for older homes, additions, or converted spaces.
  
  
• High efficiency: modern inverter technology uses less energy.
  
  

Common applications for mini-splits

Mini-splits are flexible systems that can be used in a variety of spaces, including:

• Home additions or remodeled areas without ducts
  
  
• Converted garages, basements, or attics
  
  
• Sunrooms or enclosed porches
  
  
• Multi-family units or rental properties
  
  
• Offices or workspaces within a home
  
  
• ‍Rooms that never reach the right temperature with central systems

• Energy savings: no duct losses and efficient inverter operation.
  
  
• Design flexibility: slim indoor units blend into most rooms.
  
  
• Year-round use: systems provide both heating and cooling.
  
  

Maintenance tips for mini-splits

• Clean or replace filters every 1–2 months.
  
  
• Keep outdoor condenser clear of leaves, grass, and debris.
  
  
• Wipe down indoor unit casings to prevent dust buildup.
  
  
• Schedule annual professional maintenance for coil and refrigerant checks.
  
  
• Use the system’s “dry” mode in humid weather to control moisture.

FAQs

What is the lifespan of a mini-split system?

With regular maintenance, mini-split systems often last 15–20 years.

How many rooms can a mini-split serve?

A single outdoor unit can typically support multiple indoor units, making it possible to condition several zones within a home.

Do mini-splits provide both heating and cooling?

Yes. Most models function as heat pumps, offering efficient year-round comfort.

Are mini-splits more efficient than central AC?

Mini-splits often use less energy because they avoid duct losses and allow zone-specific temperature control.

Do you provide emergency service for mini-splits?

Yes, Kelley & Dawson Service offers 24/7 emergency repair for all systems, including ductless mini-splits.
