FAQs
Why is indoor air quality so important for homes and businesses in Bristol?
Bristol’s temperate-maritime climate means buildings are often kept closed to retain heat in winter and cooled in summer, trapping pollutants such as traffic fumes, moisture and allergens indoors. Poor indoor air quality (IAQ) can aggravate asthma, cause fatigue, and reduce productivity. Our ventilation and purification solutions extract stale air, introduce filtered fresh air and control humidity, creating a healthier, more comfortable environment year-round.
What types of ventilation systems do you install?
We supply and fit a full range of mechanical ventilation systems: (1) Continuous Mechanical Extract Ventilation (MEV) for whole-house air changes, (2) Mechanical Ventilation with Heat Recovery (MVHR) that recovers up to 90 % of heat normally lost, (3) Demand-Controlled Ventilation (DCV) that modulates airflow to occupancy, and (4) Commercial ducted fresh-air systems for offices, schools and hospitality venues. All units are sized using industry software to meet Building Regulations Part F airflow rates.
How do air filtration and purification systems work, and which one should I choose?
Filtration physically removes particles; purification neutralises microscopic contaminants. We offer: • G4–M5 panel filters for general dust and pollen, • F7–F9 pleated filters for finer particulate matter (PM2.5), • Activated-carbon modules for odour and VOC removal, and • UV-C or bipolar ionisation units to deactivate bacteria, viruses and mould spores. During a site survey we test current IAQ, identify pollutant sources and recommend a combination that balances efficiency, running cost and required protection.
Are your solutions compliant with UK regulations and Bristol’s Clean Air Zone objectives?
Yes. All installations are designed to meet or exceed Building Regulations Parts F (ventilation), L (energy efficiency) and O (overheating). Equipment carries CE/UKCA marks, and refrigerants comply with F-Gas legislation. For commercial clients inside Bristol’s Clean Air Zone, we prioritise low-energy, low-emission technologies such as high-seasonal-efficiency heat-pump air conditioners and EC-motor fans to support your environmental reporting obligations.
How often should my ventilation or air-conditioning system be serviced to maintain good air quality?
Residential systems should be checked annually: filters replaced, heat exchangers cleaned and airflow balanced. High-use or commercial sites may require quarterly filter changes and six-monthly full servicing to comply with HTM 03-01 (healthcare) or BESA TR19 (duct hygiene) standards. Regular maintenance prevents performance drop-off, keeps energy costs down and preserves manufacturer warranties.
Can upgrading my ventilation and AC equipment lower energy bills as well as improve air quality?
Absolutely. Modern MVHR units recover heat that would otherwise be exhausted, cutting heating demand by up to 30 %. Inverter-driven heat-pump air conditioners deliver typical COPs of 3.5–5.0, providing 3–5 kW of heating or cooling for every 1 kW of electricity used. Smart controls further reduce run-times by matching ventilation rates to occupancy and CO₂ levels. The result is cleaner air and measurable savings, with many domestic projects paying back in 5–7 years through reduced utility bills.
