FREQUENTLY ASKED QUESTIONS - REFRIGERATED AIR CONDITIONING - SPLIT SYSTEMS

Q How big does my unit have to be?

A Because no two homes are exactly the same, a consultant from Mercury Heating and Cooling will measure and quote on the correct size. As a rough guide, 1kW will heat/cool 1 square of home.

Q If I leave the door open will it blow through and cool the bedroom or other rooms?

A Usually a split system is designed to cool only the room that it is installed in. If it is oversized then you may get some "drift" into other areas, although this is not recommended.

Q Can I get it in cooling only?

A Yes, split systems can be cool only - but the difference in price with a reverse cycle (heating and cooling) is very small - usually less than $100 - so most people choose a system that heats and cools.

Q How much do they cost to run?

A It is very difficult to determine exactly how much they cost to operate. Two houses with exactly the same systems can have huge differences on their bills, as one house may set the temperature much lower than the other (i.e. 19° instead of 23°) and may have the system operating for a much longer time over the course of 3 months - i.e. work from home. The insulation (ceiling and walls) and window coverings also make a substantial difference in operating costs.

Q Can I have multiple indoor units run off one outdoor unit?

A Yes, Multi-Head splits are an option. Although, the installation price can increase and effectiveness decrease if the indoor heads are located a long way away from the outdoor compressor. A consultant from Mercury Heating and Cooling is happy to advise on the most suitable options for the specific needs of your home.

Q Which brand is the best?

A There are a number of brands that we recommend. Mercury Heating and Cooling can supply and install a range of the best brands. Some brands suit certain applications better than others.
