Energy efficiency and air quality improved

Did you know that to maximize the performance and energy efficiency of your heating and air conditioning equipment, it is recommended that you have your air ducts cleaned at least every three years, and even more frequently in some cases (e.g., restaurants)?  

A proper duct cleaning helps counteract several factors associated with inadequate ventilation. Dust accumulation requires repetitive maintenance of mechanical components, and can lead to significant heat loss and clog filtration systems. It can also diminish the mechanical performance of your equipment and reduce its life span through overheating of the exchanger.  

Furthermore, cleaning your air ducts helps improve the quality of the air your occupants breathe daily, by removing such contaminants as dust, allergens, bacteria, microbes, moulds, germs and so on.  

We understand the importance of maintaining adequate ventilation, and that is why GMP Énergie offers you a thorough cleaning of your ventilation systems carried out by our experts, Air Systems Cleaning Specialists (ASCSs) certified by the National Air Duct Cleaners Association (NADCA). This type of cleaning allows for removal of accumulated dust and debris through a process adapted for the commercial and institutional markets.

Well-maintained air ducts help keep the ambient air clean and optimize your systems’ performance.
