Deep clean and odour treatment across Hampshire
A musty smell on start-up is the most common sign that an indoor unit in Southampton needs a deep clean. If an indoor unit in Southampton drips from the front, a blocked drain tray is often the cause, which a deep clean clears. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Prices in Hampshire
Our South East England guide price for a deep clean and odour treatment is £175–£300 per indoor unit, VAT included. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. The price depends mainly on how many indoor units need cleaning and whether the fan and coil need a full strip-down. On our South East England figures, the Two units option (deep clean of two indoor units on one visit) is about £325–£545.
One unit
Deep clean of a single indoor unit.
Two units
Deep clean of two indoor units on one visit.
Clean and service

Permissions
Cleaning the indoor unit is not refrigerant work. Anything the engineer finds beyond the clean, such as a leak or a failing fan, is explained and priced before it is touched.
The visit
A photo of the indoor unit's label and a short description of the problem help us price the visit accurately and bring what is likely to be needed. Visits in Hampshire are booked at a price agreed with you in advance. If the engineer finds anything beyond the agreed work, they explain it and price it before carrying it out.
