Home air conditioning in Ilford

Which rooms overheat first in Ilford homes?

Usually the ones at the top and the back. Ilford grew from 10,913 people in 1891 to 78,188 in 1911, and most of the new housing was long streets of two-storey terraces. Terraces are still the commonest home in Redbridge: 32.27% of its 103,713 households at the 2021 Census, ahead of semis at 26.96% and purpose-built flats at 25.36%. In a terrace the rooms that hold the heat are the rear bedroom over the back addition, especially if it faces the afternoon sun, and any loft conversion under the roof. A 2019 study of London loft conversions notes that converted lofts are found in 10.8% of the capital's dwellings. In a block, it is the top-floor flat.

How quiet is a wall unit in a bedroom?

Quiet enough that the bigger noise question is usually outside. The compressor, the loudest part, lives in the outdoor unit. For one common 2.5kW model, Mitsubishi Electric's data sheet gives the indoor unit as 19 dB(A) at a metre on its quietest setting and 42 dB(A) at full fan, with the outdoor unit at 46 dB(A). Comparing models? The figure that matters at night is the one for the lowest fan speed, so ask for that. For the neighbours, permitted development caps the calculated level at the closest door or window of their home at 37 dB(A), and we work that out before the outdoor position is fixed. The noise guide explains how. Sources: Mitsubishi Electric; Grant UK.

Is it worth trying blinds and night air before air conditioning?

Yes, if your home lets you. In Li, Taylor and Symonds' study of London loft conversions, external shutters cut overheating degree-hours by 96% and night-time purge ventilation by 89%, and ventilation came out as the most cost-effective fix. The catch is the open window. In government research published in 2019, over half of households said something sometimes stopped them opening windows, chiefly security and noise, a familiar problem for a bedroom on a busy road. The same report notes that the 26°C bedroom threshold used in overheating checks rests on a 1975 pilot study of 21 volunteers, so treat it as a guide rather than a rule. Where shade and air have been tried and the room still will not cool, a fixed unit is the next step. Sources: MHCLG, 2019; loft study.

What if you rent, or own a leasehold flat?

Then someone else has to agree first. In 2011, 22.9% of Redbridge households rented privately; by 2021 the share was 30.45%, and owner occupation had dropped from 63.6% to 57.1%, England's joint largest fall. Tenants need their landlord's permission, best obtained in writing, before any bracket goes on the wall. Leaseholders must ask the freeholder. LEASE's view is that a landlord ought not to refuse an improvement without good reason, but some leases forbid alterations entirely, and where the work touches parts the freeholder keeps, such as the outside walls, they are not obliged to agree, may charge reasonable costs and can ask for a premium. If the answer is no, look at a system with no outdoor unit. For how renting and flats shape the work locally, start at Ilford air conditioning, explained.

What size of unit suits a bedroom?

Most bedrooms fall between 1.5kW and 2.5kW. On iHeat's table a 10 to 15 square metre room starts at 1.5 to 2kW and a 15 to 25 square metre one at 2 to 2.5kW, with more for big or sunny windows, a high ceiling or a loft room. Glow Green converts at about 3,412 BTU to the kilowatt, which makes a 2.5kW unit roughly 8,500 BTU (our sum). Run in reverse, the unit warms the bedroom in winter, as our air-to-air heat pumps page explains. Sources: iHeat; Glow Green.
