FAQs
How does a whole-home dehumidifier reduce the risk of mould in my Lancing property?
Mould thrives in relative humidity above about 60 %. A whole-home dehumidifier is connected to your central heating and air-conditioning ductwork, automatically drawing moist air out of every room and expelling or condensing it to drain. By keeping indoor humidity in the ideal 40–55 % range, spores cannot germinate, damp patches dry out, and the musty odours associated with mould disappear. Because the unit treats the entire building envelope—not just individual rooms—it prevents hidden growth inside wall cavities or loft spaces, a common problem in coastal locations such as Lancing.
Will a dehumidifier make my heating and cooling system run more efficiently?
Yes. Drier air feels more comfortable at a higher temperature in summer and a lower temperature in winter, allowing you to adjust the thermostat by 1–2 °C and still feel the same comfort. Removing excess moisture also eases the workload on your air-conditioning compressor because dry air is easier to cool. Many homeowners see energy savings of 5–15 % after installation, especially during humid periods on the South Coast.
What size dehumidifier do I need for my home?
Sizing is based on the property’s square footage, typical occupancy, and existing moisture load (e.g. cooking, showers, laundry, ground-water ingress). Our Lancing technicians perform a free humidity audit using hygrometers and, when required, thermal imaging to locate damp sources. Most three-bedroom homes require a 95–140 litre-per-day unit, while larger or older properties with solid walls may need models up to 190 litres. Selecting the right capacity ensures the system cycles properly without wasting energy or short-cycling.
What is involved in the installation process?
A standard installation takes one day. We mount the dehumidifier near the air handler (often in the loft or utility room), connect it to the return-air duct, and run a dedicated drain line to the nearest waste pipe or condensate pump. A fresh-air intake can be added for ventilation if required by Building Regulations Part F. The unit is then wired to an inline humidistat and integrated with your HVAC controls so it only runs when humidity exceeds the set point. Before we leave, we demonstrate operation, register the warranty, and supply a commissioning certificate for your records.
How much maintenance does a whole-home dehumidifier require?
Maintenance is minimal: 1) Replace or clean the internal air filter every 6–12 months (it protects the coil from dust). 2) Check and flush the condensate drain annually to prevent blockages. 3) Have the refrigerant coil and fan inspected during your routine HVAC service. These steps take 10–15 minutes and keep the unit running efficiently for 10–15 years. We offer discounted annual service plans to Lancing residents that bundle dehumidifier, boiler, and AC checks in one visit.
Is a built-in dehumidifier better than using portable units?
Portable dehumidifiers are fine for a single damp room, but they have several drawbacks: limited coverage, noisy operation, buckets that need manual emptying, and higher cost per litre of moisture removed. A whole-home system, by contrast, 1) controls humidity in every room, 2) automatically drains condensate, 3) operates at 40–50 dB (quieter than most portables), 4) is up to three times more energy-efficient, and 5) adds value to your property. Over five years, the running cost of one integrated unit is typically lower than maintaining two or three portable machines.
