FAQs
Why is controlling excess moisture important in Lancing homes?
Lancingâs coastal climate brings higher relative humidity, which can lead to condensation, mould growth, musty odours, and damage to woodwork and dĂŠcor. Excess moisture also provides an ideal environment for dust mites and other allergens, aggravating asthma and hay-fever symptoms. Installing a properly sized dehumidifier keeps indoor humidity in the recommended 40â60 % range, protecting your property, improving indoor air quality, and making your home feel more comfortable year-round.
How does a whole-home dehumidifier integrate with my existing HVAC system?
A whole-home dehumidifier is plumbed into your ductworkâtypically between the return air plenum and the supply sideâso it treats all the air that passes through your heating and air-conditioning system. It draws moist air from the return duct, removes water via a refrigeration coil, and sends the drier air back into the supply duct. The collected condensate is piped to a nearby drain. Because the unit works in concert with your HVAC blower, you benefit from consistent humidity control in every room without needing multiple portable units.
What size dehumidifier do I need and how is it determined?
Capacity is measured in litres (or pints) of water removed per day. Our technicians calculate the correct size by assessing the total square footage, existing insulation, typical occupancy, number of air changes, and current moisture readings in your home. Undersizing leaves excess humidity; oversizing can waste energy and short-cycle, reducing efficiency. After a quick survey and moisture test, weâll recommend a model that matches your homeâs precise load and integrate it for optimal performance.
Will a dehumidifier increase my energy bills?
While a dehumidifier does consume electricity, most homeowners see little to no net increaseâand often a reductionâin overall energy costs. Drier air feels cooler in summer and warmer in winter, allowing you to set the thermostat a few degrees higher or lower and run the air conditioner less. Removing moisture also helps your AC operate more efficiently and can extend its lifespan. Modern whole-home units are designed with high-efficiency compressors and fans, so the typical running cost is only a few pence per day.
How long does professional installation take and will it disrupt my home?
A standard installation in Lancing usually takes 3â5 hours. We start by inspecting the HVAC system, mounting the dehumidifier on a level platform or hanging kit, connecting it to existing ductwork, adding a dedicated condensate line with a trap, wiring the control board, and calibrating the humidistat. Our team uses dust sheets and shoe covers to protect your property, and we tidy up thoroughly once the job is done. You can remain at home throughout the process with minimal disruption to your daily routine.
What maintenance and servicing does a dehumidifier require after installation?
Whole-home dehumidifiers are low-maintenance. You should replace or clean the air filter every 3â6 months, keep supply and return vents unblocked, and ensure the condensate drain stays clear. Once a year, we recommend a professional tune-up: the technician will check refrigerant pressures, clean the evaporator coil, test electrical components, and verify humidistat accuracy. Regular servicing maximises efficiency, prevents unexpected breakdowns, and maintains your manufacturerâs warranty coverage.
