I have been installing, servicing and performing start ups on LAARS Commercial and Residential equipment for 15 years. Their sales, tech support, warranty and training have always been top notch. They have never left me hanging like I have experienced with other manufacturers. I have received numerous follow up calls from them to make sure any problem I have encountered has been rectified. LAARS genuinely cares and stands behind their products.
As a service technician I constantly encounter different equipment on a day to day basis and have to say their equipment is the most reliable on the market (I have a Mascot in my house providing heat and hot water).

Will never buy another system from laars! Nothing but issues since we got it, and can't get any help from laars. Stay away from laars, all systems.

Installed a mini therm gas boiler in October of last year. So far I've went through 4 control boards, all new wiring. That process took 2 months with Laars. They sent a regional technical manager out who you could tell runs around like crazy state to state handling these cases everyday. He found all of the control boards had bad solders which were causing bad connection. He had no idea what to do other than send me 3 more boards and all of the wiring.
The issue is the red, blue and black wires behind the control board need tension to make connection. So naturally after 4 boards and all new wiring with no results I zip tied the wires to give them the tension they need. The boiler worked properly for a few more months. Still no follow up or solution from Laars. Here we are one year later from the installation and no one will respond, give suggestions or solutions.
I can't stress this enough! DO NOT DO BUSINESS WITH LAARS OR ANY LAARS DEALERS. COMPLETE RIP OFF! THEY WILL NOT HELP BECAUSE THEY CANT Update: They are now sending a new boiler (same model) we'll see if anything changes.

Just had a Laars MFTCW199 combi-boiler installed. Runs quiet, complete space saver from the old unit and considerably more efficient than the old boiler.
