A review I left on yellow pages in 2008:…read more http://www.yellowpages.com/newtown-square-pa/mip/cygnus-environmental-service-1383967 Use at your own Risk. Prices from Cygnus were the cheapest I found for duct cleaning. That being said, I think that was the only bright spot of this company. I had my ducts cleaned and it basically made my whole house dusty and floors dirty around the vents. The service is not as thorough as I liked it to be. I thought that all vents would be taken off to render the service, but it was not done so. They had a tube/device the size of a brakeline (on car brakes) that would fit throught the slits on the vents. They assured me that this would be enough. Looking at the vents from the outside, it definitely could have been better. The company pride itself as being a part of the National Air Duct Cleaners Association (NADCA) and follows it's guidelines for cleaning, but I guess removing vent covers to clean is not a requirement. After the service was done and I paid, I had a problem with my unit (fan constantly on) that I asked to have one of the guys sent out again to take a look at it. The owner asked me if everything on the thermostat says off. I tell him, "yes." He then tells me that it might be another problem with the thermostat or the unit that he and his guys would not know how to fix. I tell him it might be something small or one of the guys flipped a switch that we are unaware of. Well, basically he tells me it's my house and I should know what's wrong with it. He got irritated that I'm asking for him or one of his workers to come look at it. Keep in mind that the one of the reasons I hired this company other than price is because they were local. Long story short, he tells me to call him the next morning. I ask him, "When?" He tells me, "Anytime," but I knew in his voice this was not going to happen. I finally figured out the problem with the fan being on and there was a switch on the unit. I called the owner the next day to tell him no need to send anybody out. He never picked up his cell phone and never returned the call. Very unprofessional and needless to say, I will never use Cygnus again.

He also looked at the existing supply/return trunks, registers, calculated sq footage, air handler, ect. to evaluate that my system was loosing cfm which translates to less efficiency and higher heating and cooling costs.

Josh is also is one of the few HVAC pros that, if services are used, put the diagnostic fee towards the work order adding additional value. Thanks Bob
