"My experience was great with this company until today. They came out at the end of September, messages I have is September 25th, but not 100% sure on the actual date they came out and completed demo. Long story short, we had a bad experience with our insurance adjuster at our insurance company. Keep in mind, that I had kept Grant informed every step of the way of this process. The lady that was helping us was either fired or quit, which delayed our claim being approved. We waited a couple of weeks, trying to get in touch with our adjuster to see what was going on. We were finally assigned a new adjuster. I had to send her everything as she didn't have any of the documents/pictures/information on the claim. I let Grant know that we were assigned a new claims adjuster and that they stated it was approved. The insurance company just had to wait for them to sign off. This was Thursday, November 7th. Yesterday, November 12th, I was able to finally sign the docs with the insurance company. They stated we would have the check 5-7 business days. Again, I let Grant know via text of all this communication. Today, he called me and was extremely aggressive on the phone. Stating that I am past due 30 days and that I need to pay him immediately. Stated there is interest on my invoice that I need to pay. I wasn't aware that I would be charged interest, or I would have paid Rapid Dry a long time ago. The way he spoke to me on the phone would bring the negative side out of anyone that he talked to this way. He stated that he was extremely busy and that he had taken over 2K phone calls and didn't know if he had talked to me or not. My issue is that I have been communicating with him this entire time that we were having issues with our insurance company, and he didn't say anything about the invoice accumulating interest. I have text messages showing that I have been keeping him updated on the status of the claim. I will never use his company again nor will I EVER refer them to anyone. Not because of the work that they did, because this was good, but merely due to how he spoke to me and how aggressive he was on the phone when he just called me. Grant literally was screaming at me. After 10 minutes of a phone call with someone yelling at you and being aggressive, I think about anyone would react to this. I am extremely taken back at the way he handled himself and represented the company in the way he called me and how aggressive he was."

Air Duct Cleaning questions, answered by experts

Clean return air vents by using a microfiber cloth soaked in warm, soapy water (or a mild cleaning solution, like vinegar and water). Wipe the interior of the vents, paying close attention to the corners and crevices where dust likes to hide. Use a vacuum brush attachment or handheld model instead of a cloth if desired. Additionally, once or twice a year, remove your air vents and soak them in warm soapy water for 30 minutes before cleaning, drying, and putting them back on.

To avoid air duct cleaning scams, be cautious of offers that seem too good to be true, as they often lead to substandard services or unexpected charges. Always seek a second opinion if a contractor claims to find major issues like mold or asbestos. Hire a NADCA-certified professional to ensure you're working with a previously-vetted company or technician.

If you have dirty vent covers, clogged air filters, noisy air ducts, or weak airflow, it might be time to get your air ducts cleaned. You should also call an HVAC professional if you notice any visible mold or believe that there are rodents or insects in your ductwork. Abnormally high energy bills can also be a sign of dirty ducts.

Your evaporator coils should be cleaned at least once per year. However, the frequency of cleaning depends on your air conditioning system age and performance. If your system is old, keeps breaking down, or continues to underperform, you should have your evaporator coils cleaned twice per season. 

Your home’s location also plays a central role. For example, if you live in climates with a lot of moisture, humidity, wind, dirt, or dust, you’ll likely need to have your coils cleaned more than once yearly. 

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.
