D Bay Home Services are TOTAL SCAMMERS! I got a cold call from D BAY HOME SERVICES INC WHITBY, and decided to get the ducts cleaned for $110. Technician talked me into a furnace cleaning for another $130. They blew compressed air at my furnace for 10 minutes, and in the process, my furnace stopped working (didn't realize until after they charged me and left). It was winter, and I have 3 babies at home. I called them several times (usually got answering machine), but I got through twice, and "Amit" said both times that someone would come and fix it. After 3 days in the cold, we had to call the gas company, and they just had to connect a rubber hose that came loose from the compressed air.
The gas company said that they would never blow compressed air at the furnace.
After the furnace was fixed, I put a regular shop vac up in the duct and sucked out tonnes of debris - their vaccuum did nothing, so even if it was just a duct cleaning, it's not worth the money!!!
DON'T USE THEM!!!
