My husband and I have suffered a lot with allergies and inflammatory issues over these past few months. Ori and his partner came out and discovered we had black mold in our vents and ducts. They cleaned them out and put disinfectant for the mold and took pictures of everything. I couldn't believe we've been living with that! They also recommended putting in UV light to prevent it from coming back. Very reasonable and cleaned up everything. Couldn't be more pleased!!

They essentially scammed me. I went to them for a chimney cleaning. They told me that they would…read moreneed to do a video inspection (I didn't ask for it). They also told me that they would not do the cleaning if the chimneys failed the inspection. They came out and did a 15 min visual inspection (no video) and said the chimneys did not pass so they could not clean them. However, they charged me over $600 for the chimney video inspection and the cleaning even though they did not clean and did not do a full video. Invoice clearly states "For Services Rendered" and "for level 2 inspection and cleaning" (see photo). So they clearly charged me for services they did not deliver. This is why I call it a scam. They know I am not going to take them to court and waste my time for $600 (though I am positive I would win). I had a ridiculous e-mail exchange with the company rep where he tried to justified this. I'll post the emails in photos. They did not send me the partial refund check the rep mentions. I also subsequently had the chimney cleaned by another company without the inspection hoops Harky demanded. In my opinion, avoid Harky. There are plenty of good, honest companies out there more deserving of your business. Comment post Harky's response. Harky's comment proves my point. They talk about irrelevant information (such as my home inspection) to the fact that they charged me for services they did not provide. To be accurate, their GPS had the car on site for 38 minutes. About half that time they were sitting in their car. I assume they were writing up the invoice so they could get their money. I hope people see past this continuous BS and go to a more honest company. Good news is that I did find an honest local company, had a great experience with them and now have beautifully clean and functioning chimneys.
