Drop in Airdrie

Let's recount my experience with JPS. I've been deceived, intimidated, mislead, waiting weeks for jps information to my questions, raised voice/yelled at, haven't followed my instructions(within code), ignored, devalued my home by smell & aesthetics. And they're going to put a lien on my home. I went with JPS because I purchased my furnace from them and thought that was great(paid in full). But it was a big mistake and a huge ordeal going on months. I wanted a tankless water heater and it's been nothing but problems. They installed the tankless water and vented the piping in the front corner of my home by the walkway(street facing). I didn't agree to this. And I had to tell them that there was room from the removed water(tank) heater that the venting could be done to the back side of the home. They're accumulated years of experience was not there and lacking this acceptable solution. Then the information took weeks to come to me. They said two pipe venting that went to one pipe venting until the day of the install, back to 2 pipe venting. Their sales and installers propose different installs. JPS said they don't have time to draw out a quote with installation diagram. The don't seem to understand real estate because of the esthetics and smelling issues from the 2 pipe venting & intake. Dealing with JPS is not pleasant as they have yelled at me when they came to review the installation. Leaving messages at JPS doesn't even get a call back. They have threatened me via email to pay them otherwise they will lien my home. They have stopped replying to me. I'm in the process of looking for another vendor to remove their equipment so I can return it back to them.
