      Frequently Asked Questions About Home Ventilation

      What is home ventilation and why is it important?

      Home ventilation is the process of replacing stale indoor air with fresh outdoor air. Good ventilation helps remove excess moisture, indoor pollutants and unpleasant odours, supporting a healthier and more comfortable living environment.

      Common options include natural ventilation through windows and vents, extractor fans, whole-house mechanical extract ventilation (MEV) and mechanical ventilation with heat recovery (MVHR). The most suitable option depends on the property, its airtightness and ventilation requirements.

      The cost depends on the type of system, property size, ductwork requirements, installation complexity and whether existing ventilation needs upgrading. A professional assessment can help establish the appropriate system and installation cost.

      You can improve ventilation by opening windows when appropriate, using kitchen and bathroom extractor fans, keeping designed ventilation openings clear and maintaining existing ventilation equipment. For persistent problems, consider a professional ventilation assessment.

      Poor ventilation can allow moisture from cooking, showering, drying clothes and everyday activities to build up indoors. This can contribute to condensation and mould growth, although leaks, penetrating damp and other building defects may also be responsible.

      MVHR is a whole-house ventilation system that extracts stale air and supplies fresh outdoor air while transferring heat between the two air streams. This can help reduce ventilation heat losses in suitable, well-insulated and airtight homes.

      Yes. Insulation helps reduce heat loss, but it does not replace the need for adequate ventilation. Well-insulated and airtight homes still need a suitable way to remove moisture and indoor pollutants and supply fresh air.

      Maintenance requirements depend on the equipment and manufacturer. Extractor fans, filters, air inlets and mechanical ventilation systems should be checked and maintained according to the manufacturer’s instructions to help preserve airflow and performance.

      A suitable ventilation system can help control indoor moisture and reduce condensation risk. However, ventilation alone may not resolve every problem, particularly where there are leaks, cold surfaces, inadequate insulation or other building defects.

      Yes. Many existing homes can accommodate ventilation improvements, such as extractor fans or decentralised mechanical ventilation units. More extensive systems may require ductwork and additional building work, so suitability depends on the property’s layout and construction.
