We purchased our house last january. Our central heat/ac unit has had numerous issues from the beginning. The ac guy that our builder keeps sending out seems clueless. Anyway we finally broke down and got a second opinion from an outside ac service business. They looked at our system fixed a few things and told us that it is missing a key thing for the unit to run efficiently.
Rundown of our house-1595 living square feet- 1595 unfinished basement. All rooms are located on top floor. Basement is where the ac handler is located. We have a vent in a hallway closet. This is our return vent. This vent runs to a hole in the floor and thats it. The ac guy said that we should have duct work that runs from the hole to our handler unit. He said what we have now is a free return system. He said it is not efficient for heating in the winter.
When we contacted our builder, he stated that the return system we have is fine for our house. Who is right? Should we have duct work that runs from the closet return system to the handler or not?
Any opinions would be appreciated as we cannot find any info on the internet.
