The Colorado State University study examined two HVAC systems in the same school building. One HVAC system was professionally cleaned, including the air ducts associated with that system. The other system was left as the control. The study took place over 5 years. The main results were:
1. The cleaned system resulted in more energy savings.
2. The cleaned system resulted in better indoor air quality.
3. The cleaned system improved the mechanical life of the HVAC equipment.
A final note of importance for HVAC system and duct cleaning is that the efficacy of system cleaning can diminish with time. Efficacy means the power to produce an effect. As time goes on after the first cleaning the benefits tend to decrease. The study proved that routine cleaning is essential as a form of maintenance to ensure continued system performance.
Mr. Duct Cleaner is frequently asked, “How often should I get my HVAC and duct system cleaned?” The answer is, regularly. What is regular for your home and your other properties depends upon you, your guests, the needs of the occupants, and the demand for the HVAC system itself.
If you have a lot of pets, are a smoker, and have a lot of guests coming in and out, you probably need to have your HVAC system and ducts cleaned every two years or so. If someone is living in a household that has allergies and immune deficiencies and is sensitive to chemicals, mold, fungal growth, and dust mites, you should probably have your ducts and HVAC system cleaned every year to 18 months.
If you need continuous cleaning, the best solution is to have your HVAC system and ducts cleaned by Mr. Duct Cleaner and then have us professionally install an Aerus Air Scrubber. We give FREE estimates for the professional installation.
