FAQs
Why is a whole-home dehumidifier important for indoor air quality in Lancing?
Lancing’s coastal climate brings elevated ambient humidity for much of the year. When that moist air enters a home, it can push indoor relative humidity above the recommended 40-60 %. Excess moisture encourages mould, dust-mites and musty odours, aggravates asthma and can make your air-conditioning work harder. A properly sized whole-home dehumidifier continuously removes water vapour before it circulates through your ductwork, protecting structural timbers from rot, reducing allergens and making rooms feel cooler and more comfortable without over-cooling.
How is a whole-home dehumidifier installed with my existing heating and air-conditioning system?
Our F-Gas-certified engineers mount the dehumidifier in the loft, airing cupboard or plant room and connect it to the supply or return side of your ductwork. A dedicated condensate line is run to a safe drain point, and we wire the unit to the HVAC air handler so it operates automatically whenever humidity rises above your chosen set-point. The process usually takes one working day and involves minimal disruption—no major building work, just duct take-offs, a few flexible connections and a control cable to the wall-mounted humidistat.
What size dehumidifier does my Lancing home need?
Sizing is based on floor area, insulation level, number of occupants and the typical indoor humidity we measure during our survey. As a rule of thumb, a 3-bed semi-detached property (approx. 120 m²) needs a unit removing 20–25 litres of water per day, while larger detached homes may require 35 L or more. Oversizing wastes energy and undersizing leaves moisture problems unsolved, so we carry out a psychrometric assessment and choose a model that delivers the correct litres-per-day at local summer design conditions of 24 °C DB / 18 °C WB.
How much does professional dehumidifier installation cost in Lancing?
For a typical mid-size property the installed price ranges from £1,650 to £2,300 including equipment, labour, condensate pump (if needed), wiring, Building Regulations notification and VAT. Higher-capacity or integrated heat-pump dehumidifiers can rise to £3,000+. We provide a fixed quotation after survey, and many customers bundle the work with a replacement air-conditioning or ventilation upgrade to save on combined labour.
What maintenance does a whole-home dehumidifier require?
Service is straightforward: 1) Replace or clean the air filter every 3-6 months to keep airflow unobstructed; 2) Flush the condensate line annually to prevent algae build-up; 3) Check refrigerant pressures and electrical components once a year. During our scheduled HVAC maintenance visit we perform all tasks, verify the humidistat calibration and record performance data. With proper care, quality units last 10–15 years.
Will the dehumidifier increase my energy bills?
Running costs average 5–10 p per hour depending on model efficiency. However, by lowering humidity you feel comfortable at a slightly higher thermostat setting, enabling you to raise the cooling set-point by 1-2 °C. That adjustment can cut air-conditioning consumption by 5-15 %, often offsetting most of the dehumidifier’s electricity use. In winter, drier air also reduces condensation heat loss on windows, giving a small heating-season energy benefit.
