An air-to-air heat pump takes heat from the outside air and releases it indoors as warm air — the same equipment as reverse-cycle air conditioning, sized and set up for heating.
Working in Harrow
Harrow sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
We work across Harrow's postcode districts, including HA2. Neighbouring towns we cover include Wealdstone, Brent and Wembley. For air-to-air heat pumps in Harrow, the survey looks at where the outdoor unit can go, how pipework will reach the indoor units and whether the electrical supply has capacity.
Included as standard
- Heat loss and heat gain assessment
- Outdoor units positioned for air flow and defrost drainage
- Controls with schedules and set-back temperatures
- Commissioning and handover

The steps for a project in Harrow
Heat loss survey
We assess fabric, glazing and ventilation to size for winter as well as summer.
Design
Units are chosen for their heating output at low outdoor temperatures, not just their cooling rating.
Install
Outdoor units go where defrost water can drain safely and air flow is not restricted. We keep work areas in Harrow screened and tidy at the end of each day.
Set controls
Schedules and set-backs are configured so the system heats efficiently.
Local points to consider
Air direction
Warm air rises, so units are set to direct air down when heating.
Access and parking
Town-centre jobs in Harrow often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Defrost water
Outdoor units shed water and ice when they defrost. They need a drained position away from walkways.
Leased premises
If your Harrow premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Premises we work in around Harrow
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

Will we still need other heating?

Modern units are designed to heat well below freezing, though output reduces as it gets colder. We size for that.
