Stay away from this company they are formerly known as air care solutions ( please look up complaints) not to be confused with air care specialist which is a great company. I am a technician in the field and I come behind these animal to fix their mess ups and SCAMS! all the time they prey on the elderly and the weak I don't know how they sleep at night.. I've started a campaign on these poor excuse of businessmen I will boycott them on every known possible website I will not rest until this company goes out of business!!! beware of there sister company cool air usa which is linked to this company.
