FAQs

Why is controlling excess moisture important in Harrogate’s climate?

Harrogate sits in the foothills of the Pennines and experiences high annual rainfall and cool temperatures, creating perfect conditions for persistent indoor humidity. When relative humidity remains above about 60 %, moisture condenses on walls, windows and inside insulation, leading to mould, dust-mites, musty odours, warped woodwork, peeling paint and even structural rot. A properly sized dehumidifier keeps indoor humidity in the ideal 45–55 % range, protecting your family’s health, reducing allergens and preserving the fabric of your home all year round.

How can I tell if my home needs a whole-house dehumidifier?

Common warning signs include condensation on windows, black mould on bathroom or bedroom walls, a clammy feeling even when the heating is on, musty smells in wardrobes or the loft, cupped or swollen wooden floors, and frequent allergy or asthma flare-ups. You can also buy an inexpensive digital hygrometer—if readings stay above 60 % RH for long periods, excess moisture is present. During our free site survey we measure humidity in several rooms, inspect for hidden damp and advise whether a stand-alone room unit or a ducted, whole-home solution is most appropriate.

What types of dehumidifiers do you install and how do I choose the right size?

We install three main categories: (1) Compact crawl-space/basement dehumidifiers for properties with cellars, (2) Whole-home ducted units that connect to your existing HVAC or mechanical ventilation system, and (3) Heat-pump integrated dehumidifiers that combine cooling, heating and moisture control in one appliance. Sizing is based on the total floor area, typical moisture load (number of occupants, cooking and bathing habits), and existing ventilation. During the survey we calculate the required litres-per-day extraction rate and select a unit with at least 15 % head-room to cope with Harrogate’s damp winters.

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

For most homes we install the dehumidifier in the loft, airing cupboard or utility room and connect it to the main supply and return ductwork. A dedicated humidistat constantly monitors RH and signals the unit to run only when needed, so it works in harmony with your boiler, heat pump or AC without over-drying the air. Condensate is piped to a nearby drain or pumped outside, and all electrical work is carried out to BS 7671 standards. If you have no ductwork, we can add discreet distribution grilles or supply a stand-alone unit with its own fan system.

Will running a dehumidifier significantly increase my energy bills?

Modern whole-house dehumidifiers use efficient rotary compressors and EC fans, consuming roughly 0.3–0.6 kWh per hour of operation—similar to a desktop computer. Because dry air feels warmer, most homeowners are able to set their thermostats 1–2 °C lower in winter, largely offsetting operating costs. Lower humidity also helps your air-conditioning run more efficiently in summer, so the net annual impact on energy bills is usually negligible or even positive.

What maintenance and warranty support do you provide after installation?

The units we install carry a 5-year manufacturer’s parts warranty when serviced annually by an approved engineer. Routine tasks are simple: replace or vacuum the air filter every 6–12 months, check the condensate line for blockages and wipe the humidistat sensor. We offer affordable maintenance plans that include an annual performance check, filter change, coil cleaning and calibration of the humidistat. Emergency call-outs in Harrogate and surrounding villages are available 24/7, and most spares are kept in stock for same-day repairs.
