What is the difference between Inverter+ and Inverter++?

While both models are highly efficient, less electrical power is consumed by Inverter++ in achieving the same capacity and output as the Inverter+ models, saving money as well.

Can a single zone mini-split be used with multiple indoor units?

No. If multiple zones (indoor units) are needed, you must purchase a multi-zone system. The selection, dual, triple, quad, etc., is up to the buyer, and is dependent on the number of distinct zones, as well as the layout of the dwelling.

What type of oil is used with the unit?

Polyolester (POE) or Polyvinylether (PVE) oil.

How is power received into the units?

Only the outdoor unit is connected to the main power supply. There is a 4 lead interconnecting cable which then links the outdoor and indoor units together, giving the indoor unit power as well. The unit must be hard-wired, not plugged, into its own dedicated breaker.

What is the life expectancy of the air conditioner system?

If properly installed and maintained according to the included manuals, the system should last as long as any standard HVAC equipment, for at least 10 years or more.

When the power goes out, do the units need to be restarted manually?

No, the system has an auto-restart feature enabled (which can be disabled if needed by the owner).

What does “multi-zone” mean?

Zones are usually interpreted as the entirety of an open area. If you require temperature control of two areas that are closed off from one another, you would need a dual-zone system. Single-zone systems can be with large enough capacities to take care of areas of up to 1,600 square feet, as long as no portions of the area are closed off from the rest.

Do these Split-Type systems function as dehumidifiers?

The systems are not specifically designed as dehumidifiers, however, they do provide dehumidification functions. 

Which units are rated Energy Star?

Most Inverter++ units are rated Energy Star.

Will this work with analog thermostats, such as Nest and other 24V AC thermostats?

No, the mini split systems require their own digital controller (included) to run the complex electronics inside. You may also purchase a Pioneer WiFi module to access, program, and make changes remotely.

How much square footage will these air conditioners heat?

There is no safe and easy answer. It is important to do your research or use a relevant calculator to find the best estimate, but a good rule of thumb is 30 BTUs are needed per square foot for most standard constructions. 

What are the minimum operational Ambient temperature limitations?

The Inverter+ (17 SEER)  systems will properly operate in external ambient conditions down to +5°F in Heating and +32F in cooling modes. The Inverter++ (22 SEER) unit can properly operate in external ambient conditions down to -13°F in Heating and +5°F  in cooling modes.

What is the benefit of an inverter type air conditioner? 

Air conditioners that operate using an inverter are more energy-efficient than a typical on/off setup. Inverters “modulate” the amount of power used for operation, catering to real-time thermal demand, thereby saving energy. 

How long is the warranty?

For owners who have registered their warranties, 5 years. Otherwise, it is for 1 year.

Under what conditions am I covered under warranty?

All product warranty coverage requires a system installation that was performed correctly, following the installation manual instructions included with your purchase. Additionally, users that register their warranty card within 90 days of receiving their item get their warranties extended to 5 years for parts and the compressor. Unregistered users receive only 1 year part coverage.

Who is permitted to install the A/C?

All installation must be performed by trained persons with proper tools. Qualified installers must handle the refrigerant lines, vacuuming, refrigerant, and recharging. Electrical work and hookups must be done according to all local and national codes. Any self-installations should be limited only to assistance in mounting of the indoor and outdoor units, and performed only by persons that have the proper skillset. Local, regional, or national codes and regulations must be adhered to when installing the split system HVAC products. Warranty of the units only apply when installation has been done properly.

Is there a recommended resource to find a professional that is located near me?

Any licensed local HVAC contractor can install the products. Call as many as possible and use personal judgement as their prices and qualifications can vary. We recommend sites such as https://www.angi.com/ and https://www.homeadvisor.com/ for locating certified professionals to perform the installation. You can call your dealer where you purchased the product for recommendations.

What is the approximate cost and time spent to have the system installed?

The cost is variable. Expect to have 4-5 hours spent on the entire installation process for most common installations. Typical installation professionals charge an average of $75 per hour, and upwards.

What size torque wrench is needed?

There are two flare nuts (for 9K: ¼”-⅜”, 12K: ¼” and ½”, larger: ⅜”-⅝”) that require appropriately sized torque wrenches for proper tightening.

What gauge of wire is used for connections between the ductless mini split indoor and outdoor sections?

AWG #16 is sufficient. The wire is only used to power the indoor units, which is 50 watts at most.

What hole saw size is needed to drill the wall for accommodating the drain and refrigerant lines?

2.5 - 3 inches is sufficient.

Does the indoor unit require anything extra in order to be mounted to the wall?

No, the indoor unit comes with the mounting plate included. Nothing else is needed.

Can the unit be operated without a remote control?

In emergencies, yes. There is an emergency start button underneath the panel, which can be used until a broken remote control is fixed (turns the unit On or Off in Cool or Heat Modes, to a default temp of 76°F).

Can the line set exit from the side of the indoor unit, rather than the back/through the wall?

Certainly.

Can the line set be angled upward?

Yes, refrigerant lines can go in any direction, and the indoor and outdoor units can be higher or lower than each other. However, the indoor unit must have a condensate drain hose connection with a downward inclination. (only the ceiling cassette version comes with a condensation pump and drain that can go up to 32 inches.)

What is the weight and dimensions of the indoor unit?

Approximately 20-25 lbs. Measurements can be found in the specification materials located online. An example is the 12k BTU unit which measures 31.5x7.5x11.5 (inches).

Can the LED Display on the indoor unit be turned off?

Yes, do so by pressing the left edge of the button, where the LED letters are printed.

What is the ideal height for the unit to be mounted at?

Preferably 7 to 8 feet from the floor, and at least 4 to 6 inches below the ceiling, so that it is mounted high enough to where the air coming out of the bottom front of the unit does not get obstructed. 

Can a wall-mounted unit be mounted onto the ceiling instead?

No, because this could cause drainage issues. We offer a ceiling-mountable version specifically for that type of application.
