I have a Carrier Weathermaker 8000 gas furnace and ac unit that were installed before I bought the property -- probably around 1996 or 1997 (based on the memory of the former owner). I have had very few problems with this, except the unit doesn't cool the converted-attic MBR suite at all (it heats ok, since heat rises). My HVAC guy says that a new high-efficency furnace with 2 zones and beefier ductwork to the converted attic would solve the problem. He says my furnace is nearing the end of it's lifespan anyway, but I realize he is a salesman. Is he telling me the truth?

Do we still have a tax credit in 2011 for stuff like this? This is my residence. Thanks! --134.126.xx.xxx

Only a $300 rebate for residential units in 2011.

The problem with heating and cooling two floors with a single system: heat rises.

Therefore, you need less heat upstairs, but WAY more cooling. More heat downstairs, but WAY less cooling.

This can be overcome with a well engineered damper system. However, IMHO, the best way to overcome is to use two separate systems. If you have a single upstairs room, use a minisplit for heating and cooling.

Gas furnaces have been known to last 40 or even 50 years. They have also failed in the first year. Proper installation counts most, then quality equipment.

There are way too many variables to predict when a furnace will fail sight unseen. Generalizations for equipment work the same as for people. What is YOUR expected lifespan? You can take the national average. or a local average. But you need to factor in stuff like: your lifestyle, genetics, habits, etc. you get the picture.

Having said all, most modern furnaces are good for around 20 years. a/c is good for more like 15. --141.129.x.xx

Two of my properties have Armstrong gas furnaces that are 42 years old. And I suspect that Armstrong is not the top-of-the-line quality. --66.44.xxx.xxx

According to the IRS depreciation schedule. A furnace would be depreciated out for 27.5 years. --165.201.xxx.xxx

Yes, but according to the IRS, the entire property would depreciate to nothing over 27.5 years too -- and I'm pretty sure all of my places, which are over 30 years old, are still standing. :)

This post reminds me why I will never buy a 2 story rental house. All of the problems associated with a one level house are multiplied by 2 (or more) for a multi-level rental house. I prefer the small bungalow type houses. Small houses have small problems. --76.18.xxx.xxx

Your equipment is relatively new. I have some that are 40+. They work fine and are likely to continue to work for the foressable future. I may replace then, but only because they are much less efficient that the newer ones and therefore the heeting bill is higher. --69.221.x.xxx

Your HVAC guy is telling you important info for any of the newer equipment - it needs larger size venting and returns, this very basic concept is skipped on many replacement lo-bid jobs and the heat exchanger flexes like a jiffy-pop pan, and then someone wonders why it never saved much money over the old iron age monster anyway.

Get some prices on fixing the ductwork and let the energy savings flow your way. --76.241.xxx.xxx

This may not give you much to go on, but I have a 70 year old gravity furnace in one of my rentals, it is still going strong. --141.209.xxx.xxx

The main problem with a older gas furnace is the efficiency is very low around 60 per cent and if the heat exchanger fails there is a danger of carbon monoxide.

The question on a older furnace is getting replacement parts and a heat exchanger if the heat exchanger fails. Some furnaces can last forty years but if a furnace fails on a cold day it is very difficult to shop around for a new furnace.

Now one get a few estimates on what it costs to replace. New high efficiency furnaces can be vented directly thorough the wall without using a chimney. If one is paying for the natural gas then a high efficiency furnace will reduce the amount of natural gas required for heat. --216.110.xxx.xxx

My gas furnace is 57 years old and still strong.

If I'm reading your real quiestion: how can I cool the upstairs??

A simple window air unit for upstairs? Also keep the upper door closed in summer to "hold" the air in the room. --67.175.xx.xxx
