Healthier indoor air
Because fresh, filtered air should be part of every space.
Ellis Refrigeration and Air Conditioning LTD provides reliable MVHR (Mechanical Ventilation with Heat Recovery) installation and servicing throughout Dorset, helping homes and businesses stay fresh, healthy, and energy efficient. We also serve Hampshire, Somerset, and Wiltshire.
Mechanical Ventilation with Heat Recovery (MVHR) is a whole-property ventilation system that removes stale, moist air from kitchens and bathrooms and replaces it with fresh, filtered air from outside. As the air is exchanged, the system recovers up to 90% of the heat that would otherwise be lost, so you get a constant supply of fresh air without throwing your heating bills out of the window. Whether you are building a new home, renovating, or managing a commercial property, our certified engineers make sure your system is designed, installed, and maintained to the highest standard.

Modern buildings are more airtight than ever, which is great for keeping heat in but not so great for letting stale air, moisture, and pollutants out. Without proper ventilation, condensation, mould, and poor air quality can quickly follow.

Our MVHR service covers everything from the first site visit to long-term aftercare. This includes system design and airflow calculations, supply and installation of the MVHR unit and ductwork, commissioning and airflow balancing, routine servicing and filter replacements, fault finding and repairs, as well as upgrades and replacements for older or underperforming systems. If your property needs fresh air without the heat loss, we can design, install, and maintain the right system for you.
We provide MVHR services for a wide range of properties, including:
Whatever the case may be, we are fully capable of handling your needs.

We stand out for the following reasons:
We apply the same attention to detail and professionalism to MVHR as we do to our air conditioning and refrigeration services.

MVHR extracts stale, moist air from rooms like kitchens and bathrooms and supplies fresh, filtered air to living spaces. Inside the unit, a heat exchanger transfers warmth from the outgoing air to the incoming air, so you keep up to 90% of the heat while the air is constantly refreshed. The two airflows never mix.
MVHR works best in well insulated, airtight properties such as new builds, self-builds, and major renovations. It can also be fitted in existing homes and commercial buildings where there is space for the unit and ductwork. We can visit your property and advise on the most suitable option.
Yes. We service and repair existing MVHR systems, including filter changes, cleaning, airflow checks, and fault finding. This is ideal if you have moved into a property with MVHR already installed or your system has not been serviced in a while.
MVHR itself is not mandatory for every property, but building regulations require new homes and certain renovations to have adequate ventilation. Under the Future Homes Standard, coming into effect in England from March 2027, new homes will be more airtight than ever, making MVHR one of the most effective ways to meet ventilation requirements.
Most MVHR filters should be checked every six months and replaced every 6 to 12 months, depending on the unit, your location, and how the system is used. We also recommend a regular service to keep your system running efficiently. We can advise on a suitable schedule for your setup.
Yes. In addition to Dorset, we offer MVHR installation and servicing across Hampshire, Somerset, and Wiltshire.
We aim to keep disruption to a minimum. For new builds, installation is planned around your build programme, and for existing properties we work around your schedule to keep things running smoothly.
The cost depends on the size of the property, the type of unit, and the amount of ductwork required. We offer clear, competitive pricing with no hidden fees. Contact us for a tailored quote.
