What’s Included in an MVHR Service and How Much Does It Cost?
You step out of the shower and notice that the steam is hanging around longer than it used to. The mirror stays fogged. The bathroom feels damp. Later that night, as you’re lying in bed, you hear it again. That low humming from your MVHR system in the background.
This usually means your MVHR system is blocked. Clogged filters and restricted airflow force the unit to work hard, making it slower, noisier, and far more expensive to run – often making it even more energy-intensive as a tumble dryer.
What’s Included in an MVHR Service?
An MVHR engineer will typically:
- Measure airflow at each vent using an anemometer
- Brush and vacuum air valves and up to 2m of ductwork
- Inspect, clean, and test fan motors
- Remove and clean the heat exchanger
- Clean the internal unit compartment
- Test boost switches, timers, and humidity sensors
- Check for noise transfer between rooms
- Clean hose connections and condensate drains
- Ensure compliance with Part F building regulations
How Much Does an MVHR Service Cost?
The price will depend on your property size and system complexity.
For example, servicing a small flat with a wall-mounted Vent-Axia or Nuaire MVHR unit (around 6–7 vents) costs about £185, including new filters.
On the other hand, a larger five-bedroom house with a larger Envirovent or Zehnder system (roughly 14 vents) might be about £250 for a full service.
Why Regular MVHR Servicing is Important
Regular MVHR maintenance can prevent several problems and inefficiencies:
- Energy Efficiency: Blocked filter or intake vents can make the fan work overtime, boosting energy consumption and running costs.
- Noise Performance: A clean MVHR runs smoothly, so it isn’t as loud while in operation.
- Longer Lifespan: A neglected MVHR might need replacing in 10-12 years, but a well-maintained MVHR unit can last over 20 years.
- Reduced Repair Costs: Servicing is much cheaper than fixing breakdowns. Small issues left unchecked could require expensive repair or full unit replacement.
- Healthier Home: It also ensures that your home’s air remains dry and fresh, so mould doesn’t appear.
How Often Should an MVHR System Be Serviced
Most manufacturers suggest cleaning or replacing the MVHR filters about every 6 months. In addition, plan to get full professional servicing every 12-18 months.
The Real Cost of Skipping Maintenance
A routine service can cost around £185 to £250. However, a major part failure can cost between £400 and £1,500. Sometimes, there are limited spare parts for some MVHR models as well. This may result in full MVHR replacement, which can cost £1,500+.
Conclusion
MVHR servicing is important, especially if you want your unit to remain cost-effective, quiet, and performing well.
In the long run, a little proactive maintenance gives you peace of mind, knowing your home’s condition and your family’s health are being kept safe.
