Old House Issues


Thanks for all the ideas. I guess I'm the typical female when it comes to things like this. I know the "free" unit was just replaced because the friend is not your average flipper. She makes sure the houses she renovates has

.Free is great, deals are great. I am all for it, I search out deals, grab stuff from the trash, etc.

However, something about having a used furnace and getting someone professional to install it, just makes me cringe.

There can be so many little nuances to installing each brand of furnace, the basics are the same, but little things can be different.

Now if you were going to install the furnace yourself and you have the luxury of time, and your not paying someone $85 a hour to do the work, well then I would fell a little differently about it.

The thing is that with this old unit if the installer isn't completely familiar with the unit and they get stuck on a couple items, I can easily see it adding $500 or more to the install cost.

new units it's just something she feels strong about. The other couple of houses she has done the units have been old and needed to be replaced and it just became something that would help a new homeowner seal the

You can buy a nice quality Goodman furnace from several different places for a really reasonable price. The prices have gone up in the past 2 years since I last bought one.

This is where I have bought several furnace and AC units from:

http://www.djsonline.com/

They are a good dealer and I have never had any problems with them. They ship all over the us.

Both myself and my parents have around 3,000sqft homes, and we have the Goodman furnaces installed. We have been very happy with them. The performance has been very good.

A 69,000 BTU unit that from them is $899 for the furnace. I don't know what size you need, but even a much larger unit is within $200 of that number.

An AC compressor and coil are going to be around $1,200 for a basic unit, but there are more expensive ones that are more efficient that you can choose from. Also I don't know what size you need, so that could add a bit of cost if you need a larger one than what I looked at.

Bottom line - A Brand new quality furnace delivered to your door for about $2,200. You will need a few other items to install the furnace it's self, plus a filter.

Yes, $2,200 is a lot of money, but if you have to hire someone to do this work, then you have to consider how much money you would have to spend on a repair, what if the ignigtor goes out or the heat block cracks - $300 for one, $800 for the other - if you have to pay someone to do the repairs.

cheaper companies can come in town to supply power. It's crazy I pay two to three times the amount for a kWh than people who just live a mile or so

Well that is all the more reason to buy a new furnace with a really efficient AC unit to save electricity.

from me. I'm not sure about the square footage of the house but I will find

.Well you can just sketch up a drawing of the home, and measure, then multiple the room dimensions, and add up all the numbers.

However, there are many other factors to sizing the unit, and it is going to be really hard for you to figure out how to size your system without someone there in person helping you that has experiance.

the bids and see if it's on there. But it's a smaller home 3 bedrooms, 1 bath, kitchen and living room one story home. The cheapest estimate so far was around $ 6,000.00 which may not seem like a lot for most but it is

Are you thinking about doing any of this work yourself? This is the Do it Yourself site, It's geared towards helping people that are doing projects themselves more than just talking about contractors... That said, I happened to know a few things about this and thought I would try any help. My point was just that you may find some other sites more helpful if you just want to discuss the choice of contractors and prices.

I don't think $6,000 is unreasonable at all if they are providing the furnace, ac, new duct work install, and all the other installation related services. Keep in mind that the parts cost (outside of the cost of the duct work and a couple other incidentals) is about $2,300 for a good unit. So you are talking about the Heating contractor likely having about $3,000 cost, and is planing to charge you about $3,000 for labor. So you could have a brand new furnace for $3,000 if your willing to install it yourself.

first to turn on the heat and pull out the jacket. I think the "free" unit is a 2 ton unit I was going to get the contractor to look at it to tell me if it would be able to be used in my house. I heard that you want a unit bigger than what you need so that it will be able to run more efficiently. It that true?
.No, you want the correct size unit for heat and AC. It needs to be properly sized and you don't really want to just guess and hope it is ok.

If you are thinking about installing this yourself, I would strongly consider finding someone with considerable HVAC experience that you can hire to come out, look at your house and help you properly size the system and tell you where the ducts and returns needs to go and what size they need to be. This is the hardest part.

If you over size the A/C, you can end up with high cooling bills, not lower ones.
Both the furnace and A/C sh0uld be sized for what the house needs.

Old House Issues


LoL..Well I'm a do it yourself kinda person I have renovated the house from sanding and refinishing the old hardwood floors to hanging drywall not much I won't try (except electrical stuff). I got on here thinking I could do the duct work myself I've looked around on several sites and I think I got the main idea but....I don't want to screw anything up along the way. That's why I was going to try and cut cost using the free unit and get someone else to do the duct and hook up. I figured I would get ya'll professorial opinion. I know a couple of handy people do ya'll think that a do it yourselfer can do duct work? I've read some of the post on here and I know there are some things you don't try. I've read that you have to be good at metal work, special tool..ect. I didn't know if it was something you can get mostly put together (like pipe) with fitting and elbows ..ect. I know the 6k bid i got was the cheapest but I have heard a couple of things about the quality but the next one up was almost 1,300 more.

Most DIYers.
Have no understanding of TEL.
Total Equivalent Lenght.

Plus, they think that .1FR on a ductulatior, is the same thng as .1" ESP/static pressure.

Its not.
Plus, most don't have the tools to check static pressure.

There is a lot more to doing it right, then just using a slide calculator.

Now there's a plan. Make sure you hire someone who will respect that cool old home the way you would.

Older homes have so much character than new construction.

Off topic but I seem to do my best work in old houses. It's almost like the old home appreciate it more.

OK. I'm done visiting The Twilight Zone, carry on.
