Air Conditioning
Installation in Hertfordshire

In most cases, no. Domestic installations are covered by Permitted Development rights. Exceptions include listed buildings, flats with shared roof space, and some conservation areas. We advise on any planning considerations during the survey.

A single split system for one room typically costs £1,200–£2,000 installed. A premium single system for a larger room costs £2,000–£3,500. Multi-split systems covering 3 rooms range from £3,500–£6,000. These are complete installed prices — equipment, labour, pipework and commissioning.

Yes — all modern inverter units are reverse-cycle heat pumps. They cool in summer and heat in winter. Running an air conditioning unit in heat mode typically costs significantly less per hour than an electric panel heater.

A single split system takes one day. A multi-split with 2–4 indoor units takes 1–2 days. Larger systems take 2–3 days. We confirm the exact timeline when you receive your quote.

Very. Modern inverter units carry SEER ratings of A++ or A+++ for cooling efficiency. Running a modern split system in a bedroom overnight typically costs less than 20p.

Typically wall-mounted at low level or on a ground bracket at the rear or side of the property. It needs clear airflow and shouldn't be boxed in. We assess the best position during the survey.

Annual servicing is recommended. Systems containing more than 3kg of refrigerant require annual F-Gas leak checks — a legal requirement. Annual service costs £90–£180 per system.

A split system has one outdoor unit connected to one indoor unit — for a single room. A multi-split has one outdoor unit connected to 2–5 indoor units throughout the property. Multi-split is more cost-effective than installing multiple standalone systems.

Yes, but it requires more planning. The outdoor unit needs a suitable mounting location — typically a rear balcony, outside wall, or roof — and routing through shared areas may need building management consent. We assess feasibility at survey.

Daikin, Mitsubishi Electric, Samsung, LG and Panasonic all have strong 10–15-year reliability track records. The most important factor is correct installation and regular servicing — which is why we use only our own F-Gas certified engineers.

The refrigerant pipework is typically run in plastic conduit on the external wall. We plan routes at survey to minimise visual impact, often routing through cavities or under floors where possible. We discuss all options before starting.

Increasingly yes. UK summers are getting hotter, and a modern unit also provides heating in winter — making it a year-round asset rather than a seasonal one. The cost-per-room has dropped significantly with modern inverter technology.
