Frequently asked questions

Answers to the questions we are asked most about choosing, buying, installing and running air conditioning. Can’t find what you need? Get in touch.

Choosing a system

What size air conditioner do I need?

The right size depends on the room dimensions, glazing, insulation, occupancy and heat-producing equipment. Send us the room sizes and a few photos, or request a survey, and we will recommend a suitable system.

What is the difference between the SENDO ranges?

The SENDO ranges offer different combinations of appearance, efficiency, filtration, controls and operating features. Compare the current product specifications or ask us to recommend a model for your room and budget.

Should I choose a multi-split or separate systems?

A multi-split connects several indoor units to one outdoor unit, while separate systems give each room its own outdoor unit. We will assess the layout, available outdoor space and how you use each room before recommending an approach.

Can air conditioning heat my home?

Yes. Suitable heat-pump air conditioning systems provide heating as well as cooling. We can help you choose a model sized for the room and your comfort needs.

Buying online

Can I install a unit myself?

Split systems must be installed and commissioned by a suitably qualified F-Gas certified engineer. If you buy a unit online, arrange professional installation and check the model’s warranty requirements.

How much is delivery?

Delivery is free to eligible UK mainland addresses. Some locations, including islands and remote areas, may require a separate arrangement. Check the Delivery and Returns page or contact us with your postcode before ordering.

How does Klarna work?

Where Klarna is available, select it at checkout to view the current payment options and provider terms. Review the amounts, due dates and eligibility information shown before confirming your purchase.

Can I return a unit?

The Delivery and Returns page explains the cancellation and returns process, including the condition goods must be in. Contact us before sending a unit back so we can confirm the correct arrangements.

Installation

Do you cover my area?

We provide installation and servicing across the UK, subject to the project and location. Send your postcode through the enquiry form and our team will confirm arrangements for your area.

How long does installation take?

A typical single-room installation takes around one day. The number of rooms, pipe routes and access can affect the schedule; we will confirm timings with your quote.

Will there be much mess?

We aim to keep disruption low, protect the work area and leave the site clean. Your survey and quote will explain the proposed pipe routes and any access or making-good considerations.

Do I need planning permission?

Requirements depend on the property, its location and the proposed equipment. Mention any known restrictions when requesting a survey so the necessary checks can be discussed before installation.

Running and servicing

How much does air conditioning cost to run?

Running costs depend on the model, room conditions, electricity tariff, settings and hours of use. We can explain the efficiency information for the systems you are considering and help you compare suitable options.

How often does it need servicing?

Many systems benefit from annual servicing, with more frequent visits appropriate for heavy use or particular environments. Check the manufacturer’s requirements and ask us for a schedule suited to your system.

What warranty do I get?

Warranty cover depends on the model and the manufacturer’s conditions, including installation, registration and servicing requirements. Refer to the current product information and your written quote for the cover that applies.
