General Questions

An air-conditioning system should be tested at least once a year, or as per the manufacturer’s guidance. Regular servicing not only preserves the manufacturer’s warranty of your system, it also ensures that it stays as efficient as possible. Another benefit of having your system tested regularly is that it will catch any potential issues early, saving you money on costly repairs and reducing ongoing energy costs.
Additionally regular servicing will improve the air quality in your space aiding the elimination of harmful pathogens such as Covid-19, keeping you and your loved ones healthy and comfortable. For many systems it is a legal requirement to perform annual maintenance, and the government have the ability to penalise non-conformance with unlimited fines.

Many people are not aware that all of our air-conditioning units are classified as air source heat pumps, meaning they can also be used as the main heat source within your property. In fact, heat pumps provide a greater heating output while using three times less energy than other traditional heating systems.
If your consumer unit is over 10 years old, frequently trips or blows fuses, is damaged or rusted, or emits a burning smell, it may need testing. To prevent electrical hazards, contact a qualified Optec electrician for testing and maintenance. Regular maintenance ensures the safe operation of your electrical system.
Air Conditioning

Air conditioning systems work by absorbing heat from inside the room via the indoor unit and then rejecting this heat outside via the outdoor unit. The principle is very similar to how a domestic fridge operates. When air conditioning is in heating mode the system works in reverse absorbing heat from the outdoors and rejecting this heat in the room just the same as an air source heat pump.
Modern air conditioning systems are very economical to run. For every 1kW electricity used the air conditioning systems will provide approximately 3-4kW of heating or cooling. It is really hard to be exact on how much a unit will cost to run, as there are many varying factors such as size of the room, how well the room is insulated & energy prices. As a rough guide a small capacity unit can cost around 10 – 15p per hour to run.

For systems within commercial premises (for example, restaurants, shops or office spaces) we recommend a minimum of two services per year.
For systems within higher-risk areas, such as computer/server rooms or clean rooms, we recommend a minimum of three services per year.
