If you are in the market for a home heating and cooling system but have no ductwork and do not want to add it, a ductless mini split is your best option.

If you need cooling in Sun City, AZ, but an expensive central air conditioning system is not a viable option, ductless AC is your answer.

These compact, energy-efficient systems are perfect for home additions, accessory buildings, enclosed porches, remodeled attics and basements, and other areas not served by existing air ducts.

Adding Ductless in Arizona

Desert Diamond Air can easily make any space in your Arizona home comfortable with a ductless system. Challenges are no problem for our NATE-certified technicians, who are experts in all forms of heating, ventilation, and air conditioning (HVAC).

You can trust the Desert Diamond Air team to design, set up, and service your ductless mini split or ductless AC, maximizing system output, efficiency, and reliability. Whether you are targeting single or multiple rooms, we will help you determine the best ductless heat pump or air conditioner for your heating and cooling needs.

How a Ductless System Works

We install a heat pump or air conditioner that handles one or more compact indoor air handlers. The quiet, unobtrusive outdoor unit contains the compressor and condenser coil. It connects to the indoor units via electrical wiring and refrigerant tubing. Each indoor air handler houses a fan and evaporator coil.

The air handlers are installed high up on the wall, hidden in the ceiling, or enclosed in a console on the floor. You can position a ductless unit in just one room, a few rooms, or every room.

Each indoor unit operates independently, enabling you to set different thermostat temperatures from room to room, creating a zoned heating and cooling system and stopping the “thermostat wars” that occur in households with just one thermostat and a ducted system.

Ductless System Advantages:

  • The conduit needs a small hole to connect with an air handler. Adding or extending ductwork requires more space, bigger wall openings, and renovation to make the retrofit work.
  • A ductless system can heat and cool your home addition without placing demands on your current HVAC unit. Your HVAC system may not handle the additional square footage if you extend its ductwork to the new space.
  • A variable-speed compressor saves energy by precisely matching heating and cooling needs.
  • It improves indoor air quality (IAQ) compared to ducted systems that can collect and distribute debris.
  • Ductless units operate quietly.
  • You can avoid heating and cooling an unoccupied room by merely dialing its thermostat down or turning it off.
  • Maintenance is minimal.
  • An all-electric heating and cooling system reduces your carbon footprint.
  • Indoor air handlers are compact, lightweight, and contemporary in design.
