Types of air conditioners

Air conditioning engineers working in London will typically work with different types of air conditioning systems:

• Portable air conditioners – Small self-contained units that can be easily moved from room to room and are ideal for temporary cooling

• Split system air conditioners – A fixed system with an outdoor unit and at least one indoor unit that’s considered to be quieter and more efficient than a portable option

• Multi-split air conditioners – Similar to a split system only with multiple indoor units that allow you to control temperatures in different rooms

• Central air conditioning – A centralised system that controls the temperature of the whole building via a network of air ducts

• Heat pumps – A sustainable and energy-efficient way to heat and cool your home using air or ground sources

When choosing an air conditioning service in London, always check their experience and credentials so that you’re hiring the right person or company for the job.

An air conditioner service covers a wide range of checks to ensure your AC is functioning safely and effectively. While this may seem like an unnecessary expense, the service will pick up any issues that are developing before your unit breaks down. The service will also ensure you aren't wasting money on your energy bills.

Once you book an AC service, you can rest easy knowing an engineer will be checking:

• Electrical connections
• Airflow
• Thermostat
• Moving parts that need to be lubricated
• Condenser
• Safety controls
• Refrigerant
• Condensate drain lines
• Air filters

What about air conditioner regassing in London?

During a service, an air con engineer will check for leaks from your AC unit. Unlike car air conditioners, home air conditioners should not need to be regassed unless there’s a leak.

The standard timeframe for servicing your air conditioning unit is typically once a year.

For air conditioning systems over 12kW, a certified energy assessor must service it at least once every five years.

Benefits of regular air conditioning servicing

• A longer lifespan for your air conditioning system

• Cheaper energy bills

• Avoiding costly repairs

• Better air quality in your home

• It’s often needed to validate the manufacturer’s warranty

It might seem strange but, yes, modern air conditioning units are often designed to cool and heat your home.

How it works

Heating with air conditioning is achieved through a process called a ‘reverse cycle’.

• Cooling mode – Your air conditioning unit extracts heat from inside your home and releases it outside

• Heating mode – It effectively reverses the flow of refrigerant to extract heat from the outside air and release it into your home

That means your air conditioning unit could warm your home on a cold day just like it can cool it on a warm summer’s day.

Benefits of using air conditioning to heat your home

Here are some of the reasons why it may be beneficial to use your air conditioning to heat your home:

• Heat pumps are often more energy-efficient than traditional heating systems

• You can maintain a comfortable temperature in your home

• Air conditioning systems improve the quality of the air in your home by filtering the air and removing pollutants

• Modern air conditioning units are generally very quiet when being used

Before you fire up your air conditioning to heat your home in winter, speak to local air conditioning services available in London.

The installation time for an air conditioning system will vary depending on the type of system and the size of your property.
