I would of course recommend Infinity Air Solutions, Inc. because they do very professional work, they are very nice individuals and they are very knowledgeable.
When they are working they are very clean, their advice is correct and they don't try to up-sale you on things that you don't need. They are not trying to rack the bills.
They are also very responsive. You can call them whenever you need them and they are there. It's nice that you can deal with the owner instead of an employee because the owner is truly invested in the company's reputation of the company.
