Deep clean and odour treatment in Penarth
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. If an indoor unit in Penarth drips from the front, a blocked drain tray is often the cause, which a deep clean clears.
A musty smell on start-up is the most common sign that an indoor unit in Penarth needs a deep clean. Penarth lies roughly 3 miles from Cardiff, and we cover it as part of South Glamorgan. Postcode districts we cover here include CF64.

Labour rates in South and Mid Wales keep this slightly under the national middle.

Permissions
No planning or F-gas work is involved in a deep clean, though the engineer will tell you if the system shows signs of a refrigerant leak.
The visit
We agree the visit price before we come. On the day the engineer checks the system, carries out the agreed work and talks you through anything they find. Before booking, tell us the make and model and what the system is doing. We confirm the visit price, then the engineer arrives with the right equipment and, where possible, the right parts.
