Residential air conditioning systems use filters to prevent larger airborne particles from entering the indoor evapouration unit, so the performance, lifespan and the efficiency of the fan coil can be maintained. Whilst the standard filters supplied with most systems will inhibit dust, pollen and microfibres, some systems offer a more advanced solution that will remove other contaminants such as bacteria, mold and some viruses.



At best, the maxium efficiency of a conventional heating system is 100%, where an electric heater can produce 1kw of heat energy for every 1kw/h of electricity it uses. Other heating systems are less efficient, where even a brand new central heating boiler using mains gas, oil or LPG only has an efficiency rating of 90%.

The efficiency of an air conditioning heat pump is determined by its SCOP value,  where a system with a SCOP value of 4.7 will produce 4.7kw of heat energy for every 1kw/h of electricity it uses.

If you have a room that requires 1kw/h of heat energy and your unit price for electricity is 34p, it will cost 34p per hour to heat with an electric heater, or just 7p per hour using an air conditioning heat pump, saving a massive 78.82% on your heating bill.
