Once you’ve opted to clean your air ducts, you’ll need a professional to do it. The yellow pages are full of businesses, and a Google search yielded dozens of websites mentioning the service. With so much information out there, how can you choose a trustworthy company? I’ll provide a few pointers below.

Make sure you’re NADCA certified

An air duct cleaning certification is offered by the National Air Duct Cleaning Association (NADCA) to those who fulfill industry requirements. In addition to the three NADCA qualifications, there are two further options:

Assisting in the cleaning of air conditioning systems (basic certification)

Certified Ventilation Inspector (CVI) – Commercial Ventilation Inspector

This mold remediation system uses ventilation systems (for jobs involving mold).

Companies that have obtained any or all of the certifications above exhibit a commitment to industry standards and are likely to be superior to their non-NADCA-certified rivals.

Insist on Prior Knowledge and Experience

Many air duct cleaning businesses depend on word of mouth for new and repeat clients. Consequently, it’s reasonable to assume that a firm with a long track record has done work that its clients are happy to speak well about. Try to deal with firms that have been around for at least ten years in your neighborhood. Ask for references if you like when you call.

Angie’s List is a good place to look for testimonials.

Angie’s List (www.angieslist.com) is a website where residents post evaluations of local businesses and services they’ve used in the past. Here, you’ll receive an uncensored look at what consumers are saying about the firm that cleaned their ducts.

Do You Have Insurance? Is Your Equipment Properly Insured?

Inquire about the cleaning technique and equipment if necessary. These questions and more may be answered by trustworthy company experts. When it comes to cleaning air ducts, an examination and potentially a test of your indoor air quality are often the first steps in the process. Vents and ducts may be cleaned using specific brushes, a big vacuuming system (truck mount or gas power portable unit), and other dirt-loosening equipment if a problem is discovered by the expert technician. Hoses with large diameters remove the loosened dirt and filth from your house and deposit it in a safe receptacle for disposal. He’s also capable of devising a strategy for avoiding such issues in the future.

Don’t employ an uninsured business; insist on insurance. To safeguard you and your employees, every legitimate business should have insurance.

The Movement of Air in Mattresses

Because new, energy-saving designs restricted fresh air from the outside, interior air quality decreased in the 1970s and 1980s as builders learned to manufacture more securely sealed dwellings. “Green” home builders confront one of the most pressing challenges of our time: how to create an airtight, energy-efficient enclosure while yet allowing for healthy airflow.

There is no reason to limit airflow in mattress construction since the main purpose is to enhance airflow; there is never a need to do so. You’re looking for a mattress that lets you sleep comfortably. Mold thrives on a mattress that is overheated or damp, making it both unpleasant and dangerous. Moist, gloomy conditions are ideal for the growth of mold.

To create a bed that is both pleasant and long-lasting, mattress makers must figure out how to make it perspire. The vast majority of mattresses use some kind of foam as a cushioning ingredient. Mattresses with innersprings have foam towards the top of the mattress as well.

Natural latex foam and polyurethane foam are the two most often utilized foams in the manufacture of mattresses (natural foam rubber). Latex International gave a great presentation at the International Sleep Products Show in Charlotte, NC, in 2010 on the relative flow of air through each of these foams.

Memory foam, polyurethane foam, and latex foam were pumped with air into their chambers. A ping-pong ball was put in an open-bottomed tube at the apex of each chamber, and the ball was permitted to float above the chamber.

You’d expect the ping pong balls to rise to the same height if the same amount of air pressure and airflow were applied to each chamber and piece of foam. On the other hand, as seen in the image, the ball perched on the memory foam didn’t climb all that high! As a result of its high density, memory foam tends to retain heat and moisture. When you sleep near memory foam, it might seem like you’re lying on moist sand.

Despite the same amount of pressure, the ping pong ball traveled higher with polyurethane foam than with memory foam. Regular polyurethane foam has a higher airflow rate than memory foam. When compared to memory foam, polyurethane foam often offers a more comfortable and dry night’s sleep.

Natural latex was shown to have the greatest airflow in this test. The ping pong ball would have struck the top of the tube if the chamber’s air pressure had not been reduced for the natural latex test.

Natural latex mattresses sleep “cooler” than ones constructed of memory foam or polyurethane foam, according to this simple proof. Natural latex mattresses also retain less moisture and humidity, making the growth of mold or other germs or fungus less probable.
