I had Weiss Johnson come and remove two furnaces, redo a whole bunch of ducting, install a new high efficient furnace and also a heat pump. They went above and beyond with helping me. Relocated my hot water heater, moved and repaired a bunch of central vac lines and made everything look beautiful. Not to mention ran to my house at 9pm on a weekend to fix a small issue that could’ve waited. 10/10 from everyone involved.
had Reece and Nick from Weiss- Johnson come and install a new furnace. I have to say that I am extremely pleased with the job they did. They were very professional and pleasant to deal with. Reece is very knowledgeable and did a great job installing the new furnace answering all my questions. Nick did a great job installing the new ventilation pipes. If you are in need of a new furnace these are the guys to get.
First time using the services of Weiss-Johnson because our central ac was not starting. Celine was really nice to speak to and was very upfront about all the costs and services. Elie Haddad was our service person. Very impressed with how thorough and knowledgeable he is and quick diagnosis of the problem we were having with the AC. Will definitely hire Weiss-Johnson again for any AC and furnace related issues. Highly recommended.
