Daikin Specifics

Daikin Systems I Work On

  • Home wall units — Daikin's residential ranges, including Sensira, Comfora, Perfera, Stylish and Emura.
  • Multi-splits — one outdoor unit serving several indoor units around a home or small office.
  • Sky Air — Daikin's light-commercial range: ceiling cassettes, ducted, ceiling-suspended and wall units in offices, shops and surgeries.
  • VRV — Daikin's variable refrigerant volume systems, running many indoor units from one outdoor system.

Daikin publishes its own fault code descriptions, and those are what I work from. The codes below are the ones I get asked about most.

Fault Codes

Daikin Error Codes Explained

Common Daikin air conditioning error codes
CodeWhat it means
U4Communication fault between the indoor and outdoor units — wiring, interference or a circuit board.
U0Shortage of refrigerant — a leak, a closed stop valve or a blockage in the refrigerant pipework.
A5High-pressure control in heating or freeze-up protection in cooling — very often a clogged indoor filter.
A6Indoor fan motor locked or overloaded.
E7Outdoor fan motor fault.
A3Drain level fault on units with a drain pump, such as cassettes — a blocked drain, failed pump or float switch.
F3Discharge pipe temperature too high — often a shortage of refrigerant.
Why U0 matters: a refrigerant shortage means a leak somewhere. Topping up without finding it just loses refrigerant again. Leak-finding and repair need an F-Gas qualified engineer.

When you call, tell me the code, the model number on the indoor unit and whether it happened in cooling or heating. That usually tells me what to bring.

Every Visit

What a Daikin Service Covers

Filters, coil and fan

Filters washed, the indoor coil cleaned and treated, the fan barrel checked. A dirty filter is the commonest cause of A5 shutdowns and weak cooling.

Condensate drain and pump

Drain run flushed and tested. On cassettes and ducted units the drain pump and float switch are tested too — a blocked drain on a ceiling unit is how water ends up coming through ceiling tiles.

Outdoor unit

Coil cleaned, fan checked, fixings and anti-vibration mounts checked, and anything blocking the airflow cleared.

Refrigerant-side performance

Temperatures and running currents measured against what the unit should be doing. Signs of a leak are investigated, not ignored.

Controls and records

Remote or wired controller, schedules and any Onecta app connection checked. You get a written report with photographs.

Installation

Installing a New Daikin

If a unit is beyond economic repair, or you want cooling in another room, new single-split systems start from £1,700 fully fitted with no VAT. Daikin models are quoted at a free survey, because the price depends on the range and the room. Multi-room systems start from £3,500.

I'll tell you which Daikin range suits the room and the budget — and if another brand would serve you better for the money, I'll say that too.

Costs

Prices

Business premises: £120 for the first complete system and £90 for each additional system on the same visit. A complete system means one indoor unit and its matched outdoor unit. A twice-yearly maintenance agreement is £195 per system per year. Daikin VRF, multi-split and difficult-access systems are surveyed and quoted.

Homes: £120 for the first unit and £70 for each additional unit on the same visit.

Repairs are quoted at a fixed price before work starts. I'm not VAT-registered, so there's no VAT to add to any of it.

FAQ

Daikin Air Conditioning Questions

Yes — home wall units, multi-splits, Sky Air and VRV systems across Orpington, Bromley, Croydon and South East London. I'm F-Gas qualified.
A communication fault between the indoor and outdoor units. It can be the wiring between them, electrical interference or a circuit board. Check the outdoor unit has power first.
Shortage of refrigerant — a leak, a closed stop valve or a restriction in the pipework. It needs finding and repairing by an F-Gas qualified engineer, not just topping up.
Check and clean the filters first; Daikin lists a clogged indoor filter as a common cause. If it comes back with clean filters, the indoor coil or a sensor needs looking at.
For businesses, £120 for the first complete system and £90 for each additional system on the same visit. For homes, £120 for the first unit and £70 for each additional one. No VAT.
Yes. VRV systems are surveyed first so the visit is priced properly — it depends on the number of indoor units and access.
Yes. New single-split systems start from £1,700 fully fitted with no VAT; the Daikin model and exact price are confirmed at a free survey.
Yes. Evening, early morning and weekend visits are available for business customers at no extra cost.
