We have had a few Fire and Safety companies service our fleet extinguishers over the years.  The “other guys” never seemed to have time for us and would only service a few extinguisher at a time.  Most of the time the “other guys” would tell us they couldn’t service an extinguisher and needed to sell us a new one. Certizona is just the opposite of the “other guys”.  They are on time, very responsive and very professional.  They serviced our extinguishers on site and in a timely fashion.  They didn’t ask for our first born sons, nor did they ask for an arm and a leg.  They are fair on their pricing and eager to show us how it all works.  Everything they did was transparent and honest.  I could not recommend a company more.  Look if you have Fire and or Safety needs.  Definitely give Certizona a shot.  You will not be dissapointed.
