Q: What are the disadvantages of duct cleaning?

• <div><p>If not cleaned properly, the ductwork can become damaged, which leads to costly repairs. Some companies may use improper cleaning methods or inadequate equipment, resulting in ineffective cleaning and possible contamination.</p></div>

Q: What is a healthy air change per hour?

• <div><p>Healthy air change per hour, or ACH, rates vary by room, usage, average occupancy, and volume. The minimum ACH that's considered healthy averaged throughout the home is 0.35.

Q: Are larger ducts always better for CFM?

• <div><p>Larger ducts aren't always better for CFM (Cubic Feet per Minute). While larger ducts can handle higher airflow, they must be balanced with the system's capacity.

Q: Is it safe to run an AC with mold?

• <div><p>Is mold in an air conditioner dangerous? Running an air conditioner with mold isn&rsquo;t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it&rsquo;s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.</p></div>

Q: How do I locate where the smell is coming from?

• <div><p>While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.</p></div>
