About a month ago, a contractor came in and replaced the blow motor because hot air was not coming out of the vents. It costs me a fortune, but I was glad my house was warm again. However, I started to feel the temperature in my house is uneven, and the furnace is on more often than before. I only found out yesterday the hot air is coming out only in several rooms, not the others. (same location on both floors) That explains why the furnace was on more because the living room with thermostat has little hot air coming out.
I wonder if it is the issue with the newly installed blow motor, and should I call the contractor to check? On the other hand, I really don't want to spend more money on a 20+ year old furnace. I am thinking about replacing it, but feel bad that I just put in $+ for a new blow motor. Any suggestion? Should this be covered for free by the contractor who installed the blow motor in the first place?
Thank you so much.
