Most highly unprofessional company. I strongly recommend that nobody uses this company. As they are quick to take your money and not do a proper job. I have seen with my own eyes what there workmen’s ship is like and no knowledge what so ever. Working for a company for decades means nothing!!! They will charge you for something which is unnecessary and which can be done with your own hands. They do not fill full the general service requirements and they hit you with a huge account by doing a job which any person can do. Cleaning the filters and washing the Casing to my knowledge is not a major service!!!
