Do I need a $7000 plus new A/C/Heating System?

We just bought a house with so-called appliance insurance. This summer temp was up to 100 and my A/C can only keep inside temp as 80. so, I called a service company come to take a look. After inspection, the serviceman told me, I need a new unit, includes furnace. Reasons: A/C unit fan bearing is noisy causing fan could not chase heat out of condensor faster enough, thus, compressor is circulating liquid back to the system. And, that is why, I don't get cool air. The technician did not say the system needs some freon(??). The furnace unit is in the attic, he said the fan is rocky and the unit is too old. Not just the unit cannot perform well, it is also dangerous to use since it will pump out CO during the usage. In conclusion, he recommended us to replace the whole unit and the unit will cost about $7000. I am a Mechnical Engineer, the A/C fan bearing sound good to me, the furnace fan also rotating w/o noise. The unit is made in 1996. Do I really need a new unit?

Call a different service company, you are getting ripped off. The only CO problem you will have is if the firebox having holes allowing the CO to escape into the house, or the exhaust flue being plugged allowing CO to back up into the house. Fan bearings can be replaced, As well as the entire fan cage if required, and the cost should not be but a small fraction of what you are being quoted. Replacing the fan is a 2 hour job at most 3, and even $200 an hour flat rate only make $600 labor, another $300 for the fan unit, and even adding $100 for driving time, only comes to $1000. Leave that guy at the hitching post and make other calls quick.
Reply:i just replaced my furnace and a/c unit last year. my only advice to you is get several estimates from quality company's. don't settle on just price. a 11 year old furnace should really not have to be replaced already
Reply:I suppose you told the guy upfront that you have insurance that will pay for any repairs. $eems like he is trying to make $ome extra ca$h on that ba$i$. Get another opinion and don't let on that insurance will be paying for it, which BTW I would not have paid for myself. Quality appliances will last a long time (usually).
Reply:If you're a mechanical engineer, it might come to mind that perhaps you may need a bigger refrigeration unit for cooling, not necessarily a new unit. If your house is not insulated properly, it can be difficult to cool, or perhaps the original unit was under-specified for cost reasons.





The carbon monoxide issue must be addressed.


The statement that the unit can pump out CO during operation is true IF the heat exchanger is rusted out. Assuming you have gas heat, and if that IS the case, you should replace it.
