    For fear of getting my ass chewed out… First off I’d like to apologize up front if this is the wrong forum. I read the descriptions and this did seem the best place to make my post.

    Secondly, I’d like to thank each of you for taking the time to share your knowledge. Even for someone such as myself who wouldn’t know the difference between a compressor and a capacitor. I’m by NO means a DIY’er; I wish I was because I like to learn. But I know my limitations and prefer to leave some things to the professionals. It’s great to find so many active professionals that seem to care so much for their industry… I can only HOPE I end up doing business with someone of the caliber of professionalism I see in this forum.

    I’m about 25 days away from becoming a new home owner. I took the suggestion from a friend to not have the builder install my AC. He said that I could get a better unit and warrantee from a local HVAC company. I live in the far west burbs of Chicago and have started looking into purchasing a unit and finding a company to install. And so the fun begins…

    However, I’m finding that a lot of companies aren’t members of BBB so I’ve been unable to do much research on the customer service records of the different companies. Unlike the research I was able to do with my movers and research the Illinois Commerce Commission and BBB, there doesn’t seem to be anything that I’ve found that is similar in function. Working for a Supply Chain Association, I know that just because you say you’re a member doesn’t mean that much unless you’re active and there is no way to police that information.

    However, I like to do my homework…

    I need to find a unit for a 2860sf home with rather LARGE rooms, with another 1k sf to be added once we finish the basement. The builder of course put in the cheapest furnace they could find, Lennox G40, so I’m worried if that will cause me to have to settle with a less than acceptable AC unit. As it’s been mentioned on this board… I don’t want to end up with a system of yesterday (R22) for a house of tomorrow, so I need a unit for the house (410A/R-410). At least that much I know… I also know that sound is important as I don’t want to have to adjust the volume of my TV each time the AC kicks on to cool my home. But that’s about the extent of my knowledge for AC.

    Basically I guess my question is what should I look for or ask in regards to the company I hire to do the job? I don’t want to end up with “used car salesman" and a unit to match that is more or less than what I need. I want to do my homework, but I don’t have a clue as to know where to start, what to look for or the questions to ask. With so many brands and units under each of those… I’m overwhelmed at this point.

    Thanks for your time in reading this and to all suggestions and assistance in advance.

    I’m totally confused and not sure who to believe. I did as the above link info suggested and asked friends for recommendations and received some solid options.

    However, I’m at a lost because I’ve been told two different things.

    I spoke to one company that sells American Standard and the other Trane.

    My furnace is a single stage Lennox G40


    American Standard dealer:
    He says that based on my furnace that anything over 13 SEER is a waste as it can’t handle the higher SEER systems. However, American Standard doesn’t offer a 13 SEER so I’d have to take the Allegiance 12 SEER unit. Which means my system will be ‘out dated’ 6 months after I have it installed.

    Trane dealer:
    Now this dealer tells me that my system can hand a 14 and 15 SEER unit. Again, Trane took their 13 SEER off the market so it’s XR12 Benefits (High Efficiency Units) or the XL14i/XL15i (Super Efficiency Units) SEER units.

    On the R22 and the R410 was just a couple hundred dollar difference, but they didn’t seem at all included to push the R410 units. Both left me with the impression that I wouldn’t get any real benefit other than a slight environmental improvement over the R22.

    So, can my furnace handle and give me the full performance of the higher SEER units or am I just wasting money? Should I just take the soon to be outdated 12 SEER unit?

    Your furnace can work with higher SEER units ,just not the two speed/stage compressors.It would be more efficient with a new variable speed fan in a new furnace.

    Have you considered replacing the furnace too?Check out the Carrier Infinity,if you do.

    R410a,look to the future at, http://www.410a.com

    The higher efficiecny stuff may not be rated with a standard blower assembly. Many mfg's dont like to publish efficiencies of their higher end stuff with furnaces like yours that would in effect defeat the efficiency. Physicly it will work and fit but not as advertised. I think the first guy was trying to avoid misleading you where the second guy knows you have no way of testing SEER on your own. Dash is right, consider a whole system if you wan the whole package.

    I will be installing a 16 SEER HP on my furnace which has a PSC motor. I know my efficiency will not be what I would if I had the ECM. I am choosing to install the higher end unit because it will be more efficient than my current system and will have the added features for comfort such as 2 stage compressor and dignostics. Besides, I am sure the neigbors will be curious and want one just like it. I just so happen to know a few guys who will sell them one and install it if they want one.

    Matter of choice, if you fossil fuel a mod you deafeature it almost as much as installing a carrier.

    No seriously, Because of the duct layout in my home, I would have trouble with low static distribution (would be below .1"). There's a time and a place, the time was right, but the place was wrong. Ever try to drive a Hummer down the narrow back streets of Paris? You'd look good but the ride might be a little rough. (small cars parked, fire hydrants, small animals, they all get in the way).

    Should be easy to increase the static,and get the warehouse guy to accidentally scratch a Mod.

    No, its zoning, I would have to adjust volume dampers seasonally. Or install a zoning system.
