RightAir Solutions is a company that specialises in commercial air conditioning services.
Mechanical Ventilation with Heat Recovery (MVHR) systems should be professionally serviced at least once a year. This helps keep airflow efficient, energy usage low and indoor air quality consistently high. Additionally, MVHR filters should be checked every three to six months and replaced when necessary. Homes in urban or high-pollution areas may need more frequent filter maintenance.
MVHR systems move air through a network of ducts using supply and extract fans. Over time, dust, grease and other particles build up within the filters, ducting, heat exchanger and internal fans. This build-up can lead to restricted airflow, increased noise, higher energy consumption and eventually, system faults. Servicing keeps all components working as they should, preventing breakdowns and improving overall system efficiency.
Routine servicing also ensures your system remains compliant with the original commissioning performance. Balancing airflow rates, testing controls and cleaning internal parts are all key steps a qualified HVAC engineer will carry out during an MVHR service. Without it, the system can fall out of balance, leading to poor ventilation or pressure issues that affect comfort and air quality.
Pro Tip: Always check whether your MVHR unit’s filters are genuine replacements recommended by the manufacturer. Using the wrong type can reduce system efficiency, affect airflow balance and even void your warranty.
A professional MVHR service includes a detailed inspection and cleaning of the unit and components. Engineers will usually:
Filters play a central role in protecting indoor air by trapping dust, pollen and airborne particles. Dirty filters not only affect performance but also shorten the lifespan of the unit. Engineers may vacuum reusable filters or fit brand new ones depending on condition and manufacturer recommendations.
Wall and ceiling grilles should be free from dust, dirt and obstructions. These are cleaned and then inspected to ensure they remain secure and provide even airflow.
While a full ductwork clean is usually a separate service, the entry points are checked for blockages or excessive dust that could restrict airflow. Some providers offer deep cleans that include the full duct system.
The heat exchanger transfers warmth from outgoing stale air to fresh incoming air. Dust build-up reduces heat recovery efficiency. Engineers will check the heat exchanger, test both fans and ensure motor bearings are quiet and running smoothly.
Condensation inside the unit should flow freely into the designated drainage. Blocked pipes or incorrectly installed ducting can cause water leaks. Engineers will also check that all seals remain intact and airtight to prevent leaks or system inefficiency.
If your system has started making louder noises, is constantly running in boost mode, or rooms feel stale or humid, it could mean the unit is struggling to cope. In some cases, error codes might appear on the system’s control panel. These signs often indicate that filters are clogged or internal parts are under strain. Regular annual servicing can help identify and fix small issues before they lead to breakdowns.
Many systems now include filter replacement reminders or alert you when airflow drops below recommended levels. Homeowners should still check filters every few months, especially in city centre homes or homes near major roads where outside air contains more pollutants.

Basic maintenance tasks such as checking and cleaning filters, wiping grilles, and clearing around external vents can be done by homeowners. Always turn off the system before handling filters. For internal components like the heat exchanger, motors and airflow settings, it is best to book a professional service to avoid causing damage or unbalancing the system.
A well-maintained MVHR system can last between 15 to 20 years. The actual lifespan depends on usage, environmental factors, and how often the system is cleaned and serviced. Regular professional maintenance and timely filter changes are key to achieving long-term performance.
All types of mechanical ventilation systems, including MVHR and MEV units, should be serviced annually. This ensures consistent airflow, good indoor air quality and keeps energy costs low. More frequent checks may be needed in homes with higher dust levels or near busy roads.
Filters should typically be checked every 3 to 6 months and replaced when they show visible dirt or the system notifies you. Urban homes or households with pets may require more frequent replacements. Using manufacturer-approved filters is recommended.
MVHR systems are designed to be energy efficient. On average, they use between 20 to 80 watts during normal operation, which is similar to a small light bulb. Because they recover heat from outgoing air, they can actually help reduce overall heating costs.
