GPM Systems Inc

All went very well regarding the installation.  Couldn't be more satisfied.  GPM did a 12 month descale in 2012. However, later when I had a problem with the unit, I called GPM, advised the code on the unit, and they gave me information that it was a gas problem and to contact the gas company, which I did.  That was not the problem however, so I called GPM again, they gave me "that's the code for gas".  I then made the decision to contact the manufacturer.  They gave me several names of contacts in my area.  I contacted several and finally got a knowledgeable company who was manufacturer trained to install / service the unit.  This company was not listed when I originally took a look at certified companies.
Before we started, the first emaiIs I received in answer to a few questions I had were as follows:   "I cover entire state.  Travel charge will apply..."; "...you sure you checked your area for a local installer?"; and lastly "Sorry, I don't know any plumbers down your way.  I never turn down work." GPM accepted the install work. I did receive an email from GPM in November of 2012, after all of my "help" calls, that stated:  "Please don't take this wrong but this is one of the reasons why I said in the beginning that you should use someone more local for this work. You are a distance from my normal service area and it is very hard for me to arrange times to get down to your area on a normal call versus emergency services."
 
Therefore, I highly recommend, including myself, to confirm maintenance service is available after install.  I only recommend GPM for installation but not for maintenance.  Find someone in your local area!

Please see services performed.
