I really need some advice on what to do about our new heat pump. We are in the middle of an installation of a 3.5 ton Frigidaire (13 Seer - single packaged heat pump, single phase, Q4SD-X42K.
On start up, the unit was whistling like a train. The installers believed that it was caused by the way the air was being pulled through the fan. Next day, after talking with Frigidaire, they believe that the trouble lies with the blower assembly. Frigidaire is now sending repair parts. Also, there is a question about some dip switches that are not marked and they will be checking with Frigidaire as well to see about them.
While waiting on the parts, the techs worked on getting rid of some of the noise so that we could live with it. They believed they got rid of about 80% of the noise. However, when I got home the heat came on and it sounded like a jet engine was taking off in the room with me.
At this point, we are thinking that we are purchasing a lemon. This is a lot of money to spend. We spent about 2 weeks getting estimates and researching brands. We did not go with the cheapest by far.
The problem is, I am not sure it is wise to buy a brand new unit that came off the truck needing repairs. This is sort of like buying a new car that has a blown engine. The car would never seem new after that.
Any ideas on what is wrong with the unit? Any opinions on what a customer should do when a unit is defective when installed?
