Project title: Right-sizing rescues an over-quoted west-facing home — West Bridgford

At a glance

• Location: West Bridgford, Nottinghamshire
• Property type: 1930s semi-detached
• System installed: Multi-split — 3 indoor units, 1 outdoor unit
• Total load designed for: 7.2 kW cooling / 8.1 kW heating
• Timescale: Surveyed in March, installed over 2 days in April

The challenge

The owners struggled with an unbearably hot living room and main bedroom every summer afternoon. A previous installer had quoted two oversized units, and the couple were worried about noise, cost and having bulky boxes dominating their rooms.

What we found on survey

The west-facing bay windows were driving a large late-day solar gain, but the rooms themselves were smaller than the earlier quote had assumed. Our room-by-room calculation showed the previous specification was around 40% oversized — a system that would have short-cycled, left the air clammy, and run noisily while costing more to operate.

What we designed and installed

We specified a three-unit multi-split matched precisely to the measured loads, so each indoor unit modulates gently instead of blasting and stopping. The single outdoor unit was sited to stay discreet and quiet, refrigerant was weighed in for the exact pipe length, and we configured the controls around the family's working-from-home routine.

The result

• Even, stable temperatures through the hottest afternoons — the overheating is gone.
• So quiet the owners say they forget it's running.
• Summer electricity rose far less than the oversized two-unit alternative would have cost to run.
• The same system now heats, dehumidifies and filters the air through winter.

In the customer's words

"ArcticNord actually measured every room and talked us out of the bigger system another company pushed. It's silent, it's cheaper to run than we feared, and the house is finally comfortable in summer." — Emma, West Bridgford
