Air Conditioner Servicing by experienced staff

Our company provides affordable, expert solutions to ensure the efficient functioning of your air conditioning system.

Regular servicing of your air conditioning system is essential to ensure its smooth operation and cost-effectiveness in the long run, especially when compared to potential repairs of an unserviced system.

We can provide equipment maintenance contracts for both air conditioning systems installed by us and systems installed by others via our air conditioning engineers. This includes:

  • Regular servicing & testing
  • Detailed checklist
  • Full-service engineers
  • Normal daytime hours

Testing & Certification & Warranty

If you have specialized equipment in your workplace that requires testing and compliance, we can assist you in coordinating the necessary specialists and checks, allowing you to focus on your business. A common check, like the TM44 Form for refrigerant, requires an accredited inspector. As air conditioning specialists, we are able to arrange these checks for you.

Domestic Air Conditioning Services & Information

The air conditioning unit can be installed in various locations in your home, including some without the need for redecoration or retrofitting.

Our expert installation team can help you with these types of air conditioning systems:


Wall-mounted air conditioners are commonly installed in residential environments due to their cost-effectiveness and simple installation process. They can be easily mounted at a higher position on the wall and including some without the need for redecoration or retrofitting.

Floor or Low Wall-mounted:

Floor mounted air conditioners function in a similar manner to wall mounted units. They are positioned at floor level and can resemble radiators. This option is ideal if you prefer to conceal the unit or if it will be installed on a low-level wall, like in a conservatory.

Ducted (Concealed ceiling units)

Ducted air conditioning units offer a seamless and concealed design for homes or businesses. It is typically advised to install them during the construction phase since they require ducting throughout the entire premises and access to the loft space or may require a loft conversion.
