FAQs
What is a Mechanical Ventilation with Heat Recovery (MVHR) system and how does it work?
An MVHR system continuously extracts stale, moist air from kitchens, bathrooms and utility rooms while supplying fresh, filtered air to living spaces and bedrooms. The outgoing air passes through a heat exchanger that transfers up to 90-95 % of the heat energy to the incoming fresh air, so you enjoy a well-ventilated home without significant heat loss. Fans in the unit keep air moving through a network of small, insulated ducts fitted in the loft or ceiling voids. The result is balanced, whole-house ventilation, lower heating bills and a dramatic improvement in indoor air quality.
Why is good ventilation particularly important for homes and businesses in Harrogate?
Harrogate’s climate is cool and often damp, which can encourage condensation, mould growth and dust-mite activity inside sealed modern buildings. In addition, the town’s hard water and local pollen levels can exacerbate respiratory conditions such as asthma and hay fever. A properly designed mechanical ventilation system removes excess humidity, filters out pollen and airborne pollutants, and maintains a constant supply of healthy fresh air—helping protect both the fabric of the building and the well-being of occupants.
Will installing an MVHR or mechanical extract system increase my energy bills?
In most cases, no. Although the fans in a mechanical ventilation system use a small amount of electricity (typically 20–60 W on normal speed), the heat recovered from the outgoing air offsets far greater losses that would occur through window venting or trickle vents. Independent studies show that a well-installed MVHR can cut overall space-heating demand by up to 25 %. For commercial premises, demand-controlled ventilation can also reduce heating and cooling energy by adjusting airflow automatically to occupancy levels.
How often does a mechanical ventilation system need servicing and filter changes?
We recommend a full service every 12–18 months. During the visit, our engineers will clean or replace filters, inspect the heat exchanger, check fan performance and rebalance airflow rates. Filters generally last 6–12 months in an average Harrogate household, but homes near busy roads or with pets may need more frequent changes. Regular maintenance keeps the system operating quietly, efficiently and within manufacturer warranty requirements.
What regulations cover the design and installation of ventilation systems in North Yorkshire?
In England, Building Regulations Approved Document F sets minimum ventilation rates for new builds and major refurbishments. For energy efficiency, Part L also applies. Our engineers design all systems to meet or exceed these standards, and we provide commissioning certificates for local authority sign-off. For commercial installations, we follow CIBSE Guides B & A, plus the Health & Safety Executive’s Workplace (Health, Safety and Welfare) Regulations regarding indoor air quality.
How disruptive is the installation process and can it be retrofitted to an existing property?
For new-builds or major renovations, ductwork is usually concealed in joists or ceiling voids, causing minimal disturbance. In existing properties, we carry out a detailed survey to locate the most discreet routes—often through loft spaces, built-in wardrobes or service risers. A typical three-bedroom house takes 2–4 days to install and commission. We use low-profile, acoustic-lined ducting to keep noise to a minimum, and we leave all areas clean, tidy and re-decorated where required.
