We used this company as it was who was recommended when we bought our house. The delivery takes a few days if they are busy, and getting a service or maintenance booked can literally take months. The delivery guys are great and very helpful - the office that you call into can be a little pushy about you having to get an expensive service tech out for little things - like cleaning the safety whistle. They would have charged $200 for what took a shopvac about 15 seconds. Good service, just be wary of extra charges - ask the delivery guy first, they give honest advice.
