Just had a complete upgrade consisting of a new furnace,air conditioner & HRV unit & could not be happier with the installation by the team of Nick G.,Dave D., &Ehsan G.The installation went without a hitch,all units working excellent. Clean up great. Instructions on use great. Would highly recommend this excellent team to handle any installation you require. Cudos to Atlas for having employees of this calibre handling installations. The air quality in our home is 100% improved with the new units.
