First of all - I'm happy that my new furnace works well and I appreciate the work that the workmen did. While they were at it, they also installed two extra vents in my basement. A lot of labour goes into installing a high-efficiency furnace and I understand some things could have been missed.
There was some miscommunication as to the extent of the work - in order to install the intake/exhaust pipes and lead them outside the house, the crew cut out a vent-sized hole in my basement washroom ceiling. I was under the impression that would be patched up, apparently HVAC companies don't patch these up.
They also forgot to add screens to the intake/exhaust pipes and they made the exhaust point straight-ahead at my neighbour's basement window. My neighbour pointed it out and mentioned he faced a similar issue back when he was installing his furnace.
After some email back-and-forth the pipe was turned to the side and a screen was installed on the exhaust pipe.
Athir was kind enough to follow-up and make sure everything was in order. He explained that normally they don't recommend a screen on the intake pipe as it might cause a blockage in winter. We agreed that miscommunication happens and I appreciate him following up.
