Air Conditioning Chelmsford: F-Gas Installers

Chelmsford's commuter households often use a spare bedroom as a home office, and those rooms can get uncomfortable in summer. Most homes here are houses with gardens, which makes fitting a split system relatively easy.

Chelmsford at a glance

House types: Chelmsford is a city of houses: 31.1% of households lived in a semi in 2021, 29.6% in a detached house and 18.7% in a terrace. 19.7% lived in flats. Source

Before buying AC

Shade south and west windows, close curtains during the hottest hours and ventilate at night. If a room still overheats, a single wall-mounted split unit is the most efficient way to cool it.

Portable units need no installation but are noisier and much less efficient.

Where the outdoor unit goes

Detached and semi-detached houses, which make up over 60% of Chelmsford homes, usually have a side or rear wall that works. Keep the unit away from neighbours' windows and fix it on anti-vibration mounts.

On listed buildings or in conservation areas, check with Chelmsford City Council before installing. Flats need the freeholder's consent.

Heating too

A split AC system is an air-to-air heat pump and can heat efficiently in winter. If it replaces gas, oil or LPG heating, the Boiler Upgrade Scheme pays £2,500 through an MCS certified installer.

What to check in a quote

Look for cooling capacity per room, outdoor unit noise level, pipe route, condensate drain position and whether a new electrical supply is included. Ask how often the unit should be serviced.

Looking after it

Clean the indoor unit's filters every few weeks during heavy use, and keep leaves and garden growth clear of the outdoor unit. An annual check by an F-Gas engineer catches refrigerant leaks and keeps the warranty valid. A unit that is left dirty uses more electricity and cools less.

Chelmsford homes and what they need

Interwar and postwar semis

A side wall gives a short pipe run to the main bedroom. Converted lofts are often the hottest rooms.

Modern estates around the city edge

Well-insulated homes hold heat in summer. Check estate covenants before fitting external equipment.

Victorian terraces near the centre

Solid walls keep downstairs cooler. The back wall is the usual outdoor unit position.
