FAQs
Why should I add a whole-home dehumidifier to my existing HVAC system in Bristol’s climate?
Bristol experiences mild winters, warm, often humid summers, and frequent rainfall that can drive indoor humidity above the recommended 40–60 %. Excess moisture encourages mould growth, dust-mite populations, musty odours and damage to wood furnishings. A whole-home dehumidifier tied into your heating and air-conditioning ductwork removes this excess moisture automatically, helping your HVAC system cool more efficiently, preventing condensation on windows and improving overall comfort and indoor air quality year-round.
How do I know what size dehumidifier my home needs?
Sizing is based on square footage, ceiling height, typical indoor humidity levels and sources of moisture such as crawl spaces, basements or frequent cooking and showering. During a free on-site assessment, our technician measures your home, checks your current HVAC airflow rates and uses industry software (ACCA Manual J/S and AHAM sizing charts) to calculate the litres of water to be removed per day. Selecting the right capacity (usually 50–130 L/day for most Bristol homes) ensures the unit runs at optimum efficiency without short-cycling.
Will installing a dehumidifier increase my energy bills?
A dehumidifier does use additional electricity, but most homeowners see little to no net increase. By lowering indoor humidity, your air conditioner doesn’t have to work as hard to cool the air, often allowing you to raise the thermostat 1–2 °C while feeling the same comfort. Studies show combined HVAC–dehumidifier systems can cut cooling costs by up to 12 %. Modern units are Energy Star®-rated and include automatic humidity sensors to run only when needed.
What’s involved in adding a dehumidifier to my heating and air-conditioning system?
1. Site inspection to choose placement—typically next to your air handler or in the loft. 2. Ductwork modifications: we connect an inlet to pull moist return air and an outlet to send dried air back into the supply plenum. 3. Condensate management: a drain line or condensate pump is installed to channel collected water to a waste pipe or outside. 4. Electrical connection: the unit is hard-wired or plugged into a dedicated 13-amp fused spur. 5. Controls: we install a wall-mounted digital humidistat or integrate with your smart thermostat. The entire process takes 4–6 hours and requires no major structural changes.
How much maintenance does a whole-home dehumidifier require?
Maintenance is minimal: replace or clean the internal air filter every 3–6 months, ensure the condensate drain is clear, and have the coil inspected annually during your routine HVAC service. We offer maintenance plans that include these checks along with performance testing. A properly serviced unit can last 10–15 years.
Can a dehumidifier help with mould, allergies and indoor air quality?
Yes. Mould and dust mites thrive above 60 % relative humidity. By keeping RH between 45–55 %, a whole-home dehumidifier inhibits mould spores from germinating, reduces dust-mite allergens, and limits the growth of bacteria and musty odours. Many customers report fewer allergy symptoms, improved respiratory comfort and better preservation of wooden floors and musical instruments after installation.
