They did an excellent job on cleaning the furnace, ac, dryer vent and all our hot and cold air vents. Couldn’t be happier and would totally recommend to anyone. They also have a package of a set number of vents I think it was $160, if you have more vents they don’t charge more for the extra vents, they upgrade you to the unlimited vents package for $249, unless it is cheaper for the customer to pay for the extra vents. They will give you the best deal. For us the unlimited package was a lot cheaper than paying for the extra vents. There were no surprises, very upfront and honest and did a fantastic job. They don’t rush in and out in an hour, they do a thorough job so expect 3 hours start to finish. They also gave us a $30 discount for being a new customer.
