    From the beginning , Kirk was very professional and informative about our failed MVHR system. He gave us alternative options and came to fit the new unit with a competitive price.
    An extremely nice guy and together with his colleague provided a fantastic service.
    From my personal experience I would highly recommend this company.

    An engineer arrived in a timely manner. The job was done perfectly with a great level of professionalism. The ventilation was improved significantly. Kirk has even uncovered and fixed the issues that were unknown before. Great company providing great service!

    Cool Runnings and Kirk specifically was extremely professional, reliable and knowledgeable MVHR systems. He took the time to educate me about our system and did a very thorough job serving the system, including vents in each room. Will definitely work with him again!

    I cannot fault the service undertaken by this company to my MVHR unit, especially the expertise of both technicians Gerrard and Jed, their clean, tidy and very polite manner. I have no hesitation in recommending them.

    They are the best MVHR engineers I've ever met. They are extremely professional, always considerate of the clients, and provide a lot of useful advice. Their service is very professional and efficient, and their fees are reasonable.

    Kirk has spent a considerable amount of time discussing the ventilation requirements and solutions for my Victorian end of terrace with me. He always gets back to me and considers my questions carefully. His recommendations so far have been excellent. I will update this post once we have chosen and installed our system.
  • Avatar David James ★★★★★ 5 months ago
    Cool Runnings came to service my Vent-Axia ventilation system, they were well priced, came when they said they would and did what they said they would. The engineers who attended were professional and friendly and were happy to answer my questions. They spent the best part of an hour thoroughly cleaning and checking my system (1-bed flat) and i'm very happy with the service the provided.
  • Avatar Adam Powell ★★★★★ 3 months ago

Ventilation System Servicing

Service your Ventilation System regularly to ensure lower running costs

Our expert service and maintenance solutions keep your ventilation system in top-notch condition. From routine check-ups to emergency repairs, we ensure your system always runs smoothly.

MVHR Commissioning

Part F MVHR System Commissioning

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.

Ventilation System Servicing

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.

Heat Recovery Ventilation

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.
