Air Quality & Ventilation

  • Air Quality & Ventilation
  • Most of us in New England work in buildings with mechanical heating, cooling, and ventilation (HVAC) systems.
    These systems are designed to provide comfort and quality air, free from harmful pollutants. Ventilation is more than just moving air around, it’s quit complicated, Introducing outside air to heating and cooling air, distributing it throughout your building along with air already in your building.

    Our job @ M and R Mechanical Services is to make you comfortable at all times, we understand this complicated process and will work closely with you to ensure that your HVAC systems are functioning properly and efficiently to promote the highest levels of indoor air quality.

    How HVAC Systems become contaminated
    low-efficiency filters, lack of a filter replacement program, and improperly sized filters can all allow particles and debris to flow into a building

    • Deterioration of the insulation duct liner. Over time, the insulation fibers are distributed and blown into occupied spaces and become an eye, nose and throat irritant for some people
    • Evaporator coils become matted with dust and dirt, which insulates the coil and significantly reduces the system’s ability to cool the air; allowing for mold growth
    • Carbon dioxide (a gas that is produced when people breathe), may accumulate in building spaces if sufficient amounts of outdoor air are not brought into and distributed throughout the building
    • Failure to properly treat the water in cooling towers to prevent growth of organisms, such as Legionella, may introduce such organisms into the HVAC supply ducts and cause serious health problems.
