The Orcon MVS has been a popular mechanical ventilation unit in Dutch homes for years. Many of these systems have been running flawlessly for many years. However, over time, wear and tear and contamination can cause unwanted noises.
Do you hear a humming, squeaking, or vibrating sound from your Orcon MVS? Then it is wise to investigate the cause in time.
What are the most common noises?
Users of an Orcon MVS often report:
-
humming sound
-
squeaking sound
-
grinding sound
-
vibrations in walls or ceilings
-
increasing noise at higher ventilation settings
These complaints often start gradually and become increasingly audible.
Possible cause 1: worn bearings
The most common cause of a noisy Orcon MVS is worn bearings.
The bearings ensure that the motor can run smoothly. When they wear, the following often occurs:
-
humming sounds
-
vibrations
-
squeaking sounds
-
additional load on the motor
If this is left unaddressed for too long, further damage can occur.
Possible cause 2: fan contamination
Over the years, dust, grease, and dirt accumulate in the ventilation unit.
This can lead to:
-
fan imbalance
-
increased resistance
-
additional wear
-
more noise
A contaminated fan often runs less efficiently and makes more noise.
Possible cause 3: impeller imbalance
A damaged or contaminated impeller can cause vibrations.
This can result in:
-
humming sounds
-
resonance in air ducts
-
vibrations throughout the home
These complaints often worsen as wear increases.
Possible cause 4: aged motor components
Many Orcon MVS units are now old.
While the housing is often still fine, motor components can wear out.
This can cause:
-
decreased performance
-
noise production
-
more frequent malfunctions
In many cases, overhaul can be a suitable solution.
What can you check yourself?
Before you consider repair or overhaul, you can check a few things:
-
Check the ventilation unit for contamination.
-
Check that the unit is securely mounted.
-
Check air ducts for resonance.
-
Listen if the sound comes from the motor.
-
Check if the fan can rotate freely.
Do the complaints persist? Then a technical investigation is advisable.
When is overhaul advisable?
Overhaul is often interesting when:
-
the ventilation unit functions well otherwise
-
only motor wear is present
-
replacement is relatively expensive
-
you want to extend the lifespan
During overhaul, worn parts are replaced, and the motor is inspected and tested.
Overhaul or replace?
In many cases, overhauling an Orcon MVS is an attractive alternative to complete replacement.
Advantages of overhaul are:
-
lower costs
-
less waste
-
retention of existing installation
-
longer lifespan
For many older Orcon systems, overhaul is a very interesting solution.
