FAQs

Why would a home in Manchester need a whole-home dehumidifier?

Greater Manchester’s damp, maritime climate means indoor relative humidity can sit well above the recommended 40–60 %. Excess moisture encourages mould, dust mites and condensation on walls and windows, all of which affect respiratory health and damage décor. A professionally installed, ducted dehumidifier continuously extracts this surplus moisture before it becomes a problem, improving air quality, protecting the fabric of the building and helping your heating system run more efficiently.

How is a dehumidifier integrated with my existing heating and air-conditioning system?

During installation we tie the dehumidifier into the return-air plenum of your HVAC system or run a dedicated supply and return duct loop. The unit draws humid air through its coil, removes moisture, then sends the dried air back into the ductwork so every room benefits. A condensate drain (gravity fed or pumped) is connected to a waste pipe or outside gully, and the unit is wired to its own humidistat or to your smart thermostat so it only runs when humidity rises above your chosen set-point.

What size dehumidifier do I need for my property?

Sizing is based on floor area, ceiling height, insulation level and typical moisture load (number of occupants, showers, cooking and any basement damp). A rough guide is 0.5–0.7 L of water removal per hour for every 100 m², but we carry out a free on-site survey using BS EN 12831 load-calculation software to specify the correct capacity—usually 70–150 pints (30–70 L) per day for an average semi-detached Manchester home. Correct sizing ensures the unit runs efficiently without short-cycling.

Will installing a dehumidifier increase my energy bills?

A dehumidifier does draw electricity (about 200–600 W during operation), but by lowering humidity it lets your air-conditioning or heat-pump run less—drier air feels cooler in summer and warmer in winter. Many customers see little net change or even a small reduction in bills. We supply Energy Star–rated models with variable-speed compressors and automatic shut-off to keep operating costs as low as 3–6 p per hour at current North-West electricity tariffs.

How long does installation take and will it disrupt my home?

A standard retrofit into an accessible loft, cellar or utility cupboard takes 3–5 hours. Larger properties or those needing new duct runs can take up to one full working day. Our team lays protective sheeting, isolates the HVAC system safely and tests everything before leaving. No bricks are removed and no Building Control notice is normally required, so disruption is minimal—you can stay in the house throughout.

What maintenance does the dehumidifier require after installation?

Routine upkeep is straightforward: replace or clean the air filter every 3–6 months, flush the condensate line annually and have the coil and fan professionally inspected once a year. We offer a low-cost maintenance plan that includes a 21-point check, filter changes and extended parts warranty up to five years. With proper servicing, modern whole-home dehumidifiers have a life expectancy of 10–15 years.
