FAQs

Why should I add a whole-home dehumidifier to my heating and air-conditioning system in Lancing?

Lancing’s coastal climate often brings elevated humidity levels, especially in spring and summer. Excess moisture encourages mould, dust-mites and musty odours, and it makes your air-conditioner work harder. A professionally installed whole-home dehumidifier removes this excess water vapour before it circulates through the property, creating a healthier indoor environment, protecting furnishings and building fabric, and lowering the latent load on your AC so it can cool more efficiently.

How do you determine the correct dehumidifier capacity for my property?

Our engineers carry out a room-by-room moisture load calculation that factors in floor area, ceiling height, occupancy, insulation values, infiltration rates and average outdoor humidity in the BN15 postcode. From these figures we select a dehumidifier with the right extraction rate (litres per day) and airflow (m³/h). Oversizing wastes energy and can over-dry the space; undersizing leaves moisture problems unresolved. We provide a written sizing report so you know exactly why a particular model has been recommended.

Can the dehumidifier be integrated with my existing HVAC controls?

Yes. We typically wire the dehumidifier to the same low-voltage control circuit that runs your heating and cooling equipment. The onboard humidistat or your smart thermostat will call for dehumidification whenever indoor relative humidity rises above the set-point, regardless of whether the AC is running. For equipment with dedicated dehumidification terminals (e.g., Nest, Ecobee, Honeywell), we programme the thermostat to stage the dehumidifier separately so comfort and efficiency are optimised.

What is involved in the installation process and how long will it take?

A standard retrofit in Lancing usually takes one full working day. We start with a pre-installation inspection, confirm ducting routes, electrical availability, and condensate drain options. The unit is then mounted in the loft, utility area or plant cupboard. Our team connects supply and return ductwork, installs a rigid or insulated flexible trunk, fits isolation dampers, wires a fused spur or plug socket, and routes the condensate line to a waste or external soak-away in compliance with Building Regulations Part H. We finish with commissioning tests, humidity calibration and homeowner training.

How much does a professionally installed whole-home dehumidifier cost and will it save me money?

For an average three-bed Lancing property the supplied-and-installed price typically ranges from £1,950 to £2,800 including VAT, depending on capacity, ducting complexity and control options. Running costs are low: most units draw 200–600 W and operate intermittently, so annual electricity use is around 200–350 kWh (£60–£100 at current tariffs). Savings come from lowering air-conditioning runtime, preventing moisture-related repairs, and improving the lifespan of your HVAC system. Many clients also report they can raise the AC set-point by 1–2 °C and still feel comfortable, trimming cooling bills further.

What maintenance does the system require and do you offer service plans?

Maintenance is straightforward: clean or replace the air filter every 3–6 months (more often during high pollen seasons), check the condensate drain for blockages, and have the refrigeration circuit, fan and humidistat inspected annually. Our ‘ComfortCare’ service plan starts at £9.95 per month and covers one annual inspection, priority call-outs, parts & labour discounts, and extended warranty handling. Regular upkeep keeps efficiency high and protects your manufacturer’s warranty.
