I am sorry this is long, but worthwhiile reading!
The company cold solicited by phone and changed the date and time several times. They had low customer service overall. No nametags, one in an AQ shirt, the other in street clothes. Talked on the phone during the service etc. Two guys began with "where is the best place to access your furnace, ma;am?" They did remove their shoes at the door, but I know that work standards for the proper equipment means that they should be wearing safety boots and not remove them but put down area protection. But there was a truck mounted system, so I gave it a chance. The technician ran his finger through surface dust in my basement and said he could tell I needed a furnace cleaning and air conditioner cleaning as well. I said that was not what I could afford today, nor what I had agreed to. I told them right off the bat that a cleaning should involve the handlers/exchangers and the vent system. I had a company to take care of the furnace and that my air conditioner was less than a month old and that if he was trying to upsell me without even turning the system off opening anything up, then I was concerned about this company's integrity and that perhaps he was trying to scam me. He then proceeded to cut a hole and hook up a large hose to the duct. with no warning at all, (No, may I or ma'am this time) The "duct cleaning" turned out to be a suctioning of my system and a spray nozzle with sanitizer (though I wouldn't know if it was sprayed with sanitizer or not-is it a liquid?)
My system was not turned off, only the basement duct was hooked up to a truck mounted vacuum. The spray wand was on a one inch diameter hose with a hard foot long metal nozzle and this was used in between the vents on my return air (yes, stuck through, not removed.) They are now bent. Then all the vent covers were lifted and this sprayer was used to blow down into each vent. This caused lines in the dust, and scratching and the edges are bent over, I am now worried about damage to my one year old system. They left with the agreed upon amount of 195.50 in cheque form, which at first was refused. They wanted a debit payment with a handheld unit. I explained that this was the payment I had, I did not have the money in my chequing account and I do not use credit cards, that I was using my line of credit. He continued to insist on a cash, debit or credit payment as people pay with cheques when they have no money to pay.. I explained that I am a teacher and it is a good cheque, the last thing I needed was to get in trouble legally, why would i make a bad cheque? I told him that they had never specified what payment type and that I had looked on the side of the truck and checked out their website and there was no information there either. They unhooked and left fast, without even an invoice given.
I would NOT reccomend this company!
