    What does high efficiency furnace mean to you???

    Flipping through our monthly mailer we get packed full of various coupons. Add for heating air company. Advertised a very attractive price for a high efficiency furnace install.

    So what do you consider high efficiency???

    I’ll be back after a while to fill in what they call high efficiency furnace and ac.

    More things to go wrong than a mid efficiency for not that much in savings. In the midwest and south anyway...with natural gas.

    I suppose you're really looking for a percentage point. It won't be as high as advertised and the nuisance calls and increased initial cost will eat it up in no time.

    Exceptions, of course, for those who install properly.
    Is the Religious Right to blame for Christianity's decline?

    They argued that, as the Religious Right became increasingly visible and militant, it became associated with Christianity itself. And if being a Christian meant being associated with the likes of Jerry Falwell, many people—especially political moderates and liberals—decided to simply stop identifying as Christians altogether.

    Savings on energy, not necessarily saving money.

    The words high efficiency are really meaningless words.

    I wouldn't use those words connected to a furnace unless it was 90% or above.

    I bet they are talking about an 80% furnace.

    ef·fi·cient
    /əˈfiSHənt/

    adjective
    (especially of a system or machine) achieving maximum productivity with minimum wasted effort or expense.

    Similar:
    well organized
    methodical
    systematic
    structured
    well planned
    logical
    coherent
    well regulated
    well run
    well ordered
    orderly
    businesslike
    systematized
    streamlined
    productive
    effective
    labor-saving
    cost-effective
    energy-efficient
    energy-saving
    fuel-efficient
    Opposite:
    inefficient
    disorganized
    preventing the wasteful use of a particular resource.
    suffix: -efficient
    "an energy-efficient heating system"

    That being said....What does high efficiency mean to me?
    Lowest cost to operate.

    If the operational costs negate the savings, there is no efficiency. My 80% Goodman furnace and 10 seer a/c I installed 17 years ago in my house and has cost me nothing more than utility costs, filter changes and an inducer motor. It is highly efficient. Had I installed a 90+ 17 years ago and done nothing but filter changes and an inducer motor, I'd be ahead of the game. Unfortunately, that is not usually the case.

    In my area it's a 2 stage 80% with a variable speed blower. My honest thinking is a 90+ but our winters are couple cold days followed by running AC a few days most years. In all my years only installed three 92% furnaces on a plan/spec school job & serviced one Sears 90+ . What's crazy is that school job was dual fuel hp's. I don't think they ran long enough to ever save enough to pay for the job.
    I replaced a standing pilot furnace on propane when the 80% first came out. It cut the customers propane use so much his supplier that also rented him a tank put a padlock on the tank thinking someone else was selling him propane

    We consider it a (category 4) condensing furnace . I'm sure they define it otherwise.

    According to this coupon, high efficiency is 80% and super high efficiency is 96%.

    I guess to each his own. But I have always referred to, especially in this day and age, as high efficiency is 90+.

    In WNY, 96% is our high efficiency.

    I don't have a dog in this fight, but my understanding is that "high efficiency" starts with the first condensing furnace in the product lineup. I would guess that starts at around 90%.

    There is nothing more “efficient” than an electric resistance heat air handler. Do they still make natural draft furnaces?

    Maybe that was a flyer from the 80's or 90's when that would have made sense?

    Reminds me of when I once went through a McDonald's drive through and asked for a small fries and was told they didn't have a small fry. They went M, L and XL or something like that.

    If it's replacing an older furnace or ac then anything is higher.
