Dan LincolnTrustindex verifies that the original source of the review is Google. Great experience - the guys were easy to coordinate with and it was a very professional service - I will definitely use them again! Camille NockTrustindex verifies that the original source of the review is Google. I had such a great experience with Jerald & Zeth of Cool Runnings. They completely fixed my ventilation system that was in dire need of cleaning and servicing and they were so lovely, hard working, efficient and completely fixed our system! We will only call on Cool Runnings from now on! And make sure we have regular check ups. Thank you to the whole team again Marc BolgerTrustindex verifies that the original source of the review is Google. It was easy to book the MVHR service over WhatsApp. The engineers arrived on-time and one replaced the fans and checked the Unit, while his colleague cleaned all the Vents. Very efficient and tidied up after. They also checked the ventilation settings and humidistat (which was incorrectly set at 100%, so it would never have boosted despite damp bathrooms!) Thanks! Ben ClayTrustindex verifies that the original source of the review is Google. Used Cool Runnings to initially come and assess my Nuaire MRXBOX MVHR unit. They diagnosed the problem and attempted to fix it but unfortunately the manufacturer had stopped producing the relevant parts. They provided the best quote of any of the providers I spoke to for the replacement and commissioning of a new unit, including throughly cleaning the old vents. Jerald and Antonio were polite, punctual and professional. Would recommend to anyone. Thomas McLachlanTrustindex verifies that the original source of the review is Google. Kirk and team went to great lengths to work around a problematic access issue and provided advice on how to resolve it. Most engineers would simply ignore a job like this. Really appreciated the extra care. Pankaj GorapalliTrustindex verifies that the original source of the review is Google. I’m extremely happy with the MVHR service carried out today at my flat. Jerald was excellent — very professional, punctual, and clearly very knowledgeable. He took the time to explain how the unit works, what was being checked/serviced, and why proper air circulation is so important. I genuinely learned a lot during the visit. Great service overall and I would definitely recommend. Laurie JacobsTrustindex verifies that the original source of the review is Google. Antonio visited today to carry out the service of my Nuaire mvhr unit. The service from start to finish was incredibly thorough and thoughtful handled taking care to clean as he went and demonstrate the elements of the service. Would highly recommend Susan JeffTrustindex verifies that the original source of the review is Google. Absolutely fantastic service provided! Jed the engineer arrived and immediately placed shoe covers on before entering my home. The photographs shown of the before and after of the works carried out, with clear explanation was enlightening (next time I won’t leave it so long). I can actually feel the air circulation has been restored. Jed was professional, courteous and I would highly recommend this extremely competitive company. Many thanks indeed! jamie merrinsTrustindex verifies that the original source of the review is Google. Great service, helpful and incredibly friendly. Have recommended to friends.

If your ventilation system has stopped working, has a red failure or flashing light, has become noisy and there’s condensation forming on walls and windows get in touch, we can help you.
A ventilation system should not over or under-ventilate the rooms in your home. We test and commission the system to meet your property size’s correct airflow rate requirements. Your ventilation system should not consume more energy than needed.
When the ventilation system moves air around, dirt and dust travel with it. After a while, dirt builds up in the ventilation unit, the duct, and the air rings in the ceiling, clogging them up and slowly decreasing the airflow. Scheduling a service to remove as many of the blockages in the system as possible is important, as this allows the airflow rate to improve, thus preventing condensation and mould issues in your property. MVHR, MEV and Bathroom Extractor fan units work more effectively when maintained regularly.
The job of an MVHR or Mechanical Heat Recovery Ventilation system is to replace the stale air in every room with fresh, filtered air. When set correctly, the heat recovery system will recycle the waste heat created from your showering and cooking activities. The MVHR system must never be switched off. It saves the average household at least £300 a year and costs only £40 a year to run. Vent Axia Sentinel Kinetic, Nuaire MRXBOX , Titon HRV, Greenwood Airvac, Envirovent and Vectaire are some of the most reliable brands of MVHR models.
Professional MVHR commissioning ensures your ventilation system is correctly installed and balanced. The process itself is also mandated by Part F of the UK Building Regulations, making it a legal requirement.
Our commissioning service provides you with a Part F Ventilation Certificate. This ensures your MVHR system delivers optimal indoor air quality, reduces energy consumption, and prevents mould and condensation issues, all while being legally compliant.










If you want to verify whether your MVHR unit or model is covered, please don’t hesitate to contact us.
