FAQ

What is a ductless mini-split system?

A ductless mini-split system is comprised of an indoor unit called the evaporator and an outdoor unit called the condensing unit. The evaporator is connected to the condensing unit by copper tubing and electrical wiring which is passed through a 2 ½" - 3" hole. Basically, it is a small central air unit with the flexibility of cooling or heating one room or more; zoning.

What are the advantages of installing a Fujitsu General ductless mini-split over a central air system?

  1. With Central Air you must cool an entire home when only one room may need cooling. On the other hand, ductless mini-splits cool only the areas you want and not the areas you don't.
  2. 18,000 BTU is a typical minimum central air unit. With ductless mini-splits, you can use 7,000, 9,000 or 12,000 BTUs.
  3. Typical 3-ton homes are not zoned or require complex zoning systems, which makes it very expensive for the homeowner. With ductless mini-splits, multiple evaporators make zoning as simple as setting a remote control.
  4. Energy wasted in long lengths of uninhabited ductwork means higher energy bills. Less than 5% cooling loss occurs in insulated refrigerant lines compared with up to 25% through ducts.
  5. Retrofitting homes require cutting holes in walls, floors, ceilings or decreasing closet space with ducts. Ductless mini-splits requires just a 3 or 4 diameter hole in the outside wall. Means less mess and better home aesthetics.

What do my typical savings look like with a heat pump?

A heating a home with a heat pump is one of the most energy efficient ways to do so. A ductless heat pump can save you 30 - 40% or more on your utility bill.

How does my heat pump work?

Instead of using energy to create heat, the heat pump extracts heat from the outside air and transfers it into the home.

What temperature is a heat pump not effective?

Typical range is -15 °C to -30°C but, every heat pump model is different. Always check your models rating.

Should only run my heat pump during the day?

It's generally much more efficient to leave your heat pump running continuously because heat pumps are more efficient when they heat or cool your room at a consistent rate.

What cleaning is required to maintain my heat pump?

Every 2 weeks check and clean the filters on your indoor-condenser unit, to keep it running efficiently.

Do I need to clear the snow/debris from the outdoor unit of the heat pump?

Air flow is paramount to the operation of the unit. Please ensure snow and debris is cleared a minimum of 2-3 feet around your unit. Failure to maintain proper air flow to the unit, even in short periods, can result in damage to the unit.

Why does cold air blow when the heat pump starts up?

When the heat pump and indoor condenser unit turn on at the same time there might be a bit of cold air blowing while the heat pump's refrigerant takes a minute or two to build up heat.

Why is my heat pump making a vibrating noise or a rushing water sound?

This normal and typically means is the heat pump going through the defrost cycle. The defrost cycle is where the unit temporarily reverses the flow of refrigerant which results in a vibrating noise and rushing water sound but, is necessary for your heat pump to maintain efficiency. If you hear these noises leave the unit alone and let it go through its cycle.
