10/10 via Homestars
I have been looking where to purchase a air conditioner and or to rent one, alot of companies seem shady in respect to the warranty service. I found Demark to be upfront and sent an email in detail as to what they cover warranty wise. They even installed the unit the next day which is great, no waiting. I was pleased with the service for sure.
