Now I need to look into options for improving the insulation of the attic.

He started by going over a printout of the last year of my energy bills. He gave me an idea of the averages used by other similar houses and let me know where our usage for the past year falls on that scale.

When I told him were looking at the possibility of replacing our furnace and adding central air, he explained to me the factors that go into determining the size of units we need.

1. Square footage to heat and cool
2. Number of windows and doors on exterior walls
3. Existing value of insulation

With that in mind, he figured that our house probably needs a 60,000 BTU furnace.

Now, one important thing about the existing furnace is that the home inspector we had to look at it wrote down the wrong date for when our current furnace was installed. He accidentally wrote down 1983, which is correct for the water heater. But the furnace was installed in 1997! Keep in mind that three contractors came out and looked at our furnace and also didn’t notice what year it was, or did notice and didn’t choose to point out that our furnace is supposed to last 20 years and probably doesn’t need to be replaced. We were thinking of replacing it based on it being nearly 25 years old! With this new information, we’re not necessarily bent on replacing the furnace part. It’s still under consideration.

He went through the house and helped me identify the weakest spots in our insulation. A lot of that was painfully obvious, but it was good to get a few suggestions on how to most cost effectively repair those weaknesses.

One major weakness is the coal chute. He recommended bricking it up with hollow glass bricks. That way we can let in light, but it’ll be a good insulation for the spot.

Another important aspect of our insulation that’s lacking is the attic. Everyone thusfar has described the attic as a “half story” but on account of the insulation properties he noted, the MidAmerican guy said it’s just a converted attic. The things that indicated to him that it’s never been considered “living space” are that the floor and crawlspaces are packed with insulation but there’s no insulation under the roof. He said I can change that and then it’ll be more efficient, but it will require tearing down the plaster and lath ceiling, insulating that space under the roof, and then putting up drywall. I suppose that’s an option, but I think we’ll go ahead and improve the window insulation, put doors on the crawlspaces, and see how well the place stays heated and cooled this year before deciding to add that task to our list. It may be possible to remove some of the insulation from under the floorboards in the meantime, but I don’t think that’s really even necessary.

Finally, he was satisfied with my intentions to fix the windows, but told me it would be wise to insulate the walls. They currently have nothing inside them. He recommended hiring a contractor to blow insulation in from the outside. They’d have to take off the top strip of siding, drill the holes there, blow the insulation in, and then put the siding back. Also, his suggestion for agreeing on price was to say we’ll pay you for the labor, plus we’ll count up the bags of insulation at the end of the job and pay you according to that. That way they have more incentive to use more insulation in our walls so they can get paid more for it, thus doing a better job of insulating the place.

Now that I have specific recommendations for improving the insulation, I can qualify to have MidAmerican energy pay up to 70% of the cost of insulating my house, up to $600. We’ll probably apply that to having the insulation blown into the walls.

So with all that information in mind, we’re going to contact back the people we got quotes from, ask them to adjust the quotes for leaving the current furnace and just adding A/C and ductwork and then see what we’re facing as far as cost. I’m guessing it’ll just be as simple as deducting the cost of the new furnace from the total and probably adjusting the labor cost a bit, but I guess we’ll see.

Part of what’s got us so busy this week is that we’re gathering quotes to replace our furnace and add A/C. We were planning to wait until the weather warmed up to replace our furnace.  No, I lie.  We were putting off replacing our furnace indefinitely.  But an ad we received in the mail for a local company reminded us that it’s the off season for purchasing a new furnace, so we’d probably get a better deal doing it sooner than later. 

We called the company in the ad, Leechman Heating and Cooling, a Service Master company, to come over and give us a “comfort assessment.”  He had a worksheet to fill out that asked about what’s comfortable about our house, what’s uncomfortable, and what we’re looking for as solutions.  He measured all the rooms, walked through the house recommending new supplies and changing around returns in most of the rooms, checked out our existing unit for us, and took all this information back with him to his company.  We scheduled a time for him to come back this week and discuss what he put together for us, so he came back last night. 

He came back with two options.  One with a heat pump, a 92% Amana Distinction furnace, a builder’s model humidifier, and added duct-work in our house is $7891.  The other with a 92% Amana Distinction furnace, a 14 SEER A/C and a builder’s model humidifier (plus additional duct-work) is $6824.00. 

 Both options include a really good warranty, and their own company’s service warranty is included with the installation.  Also, they provide a digital, programmable thermostat.

We’re getting two other quotes from two other smaller, more independent companies later this week/early next week. 

 One of the big questions I have for the other two people coming to look at our house is whether the additional duct-work and supplies/returns are really necessary or all that beneficial.  Another is about heat pumps vs. air conditioners. 

I’d welcome any advice, links, or wisdom from my readers on this topic (as always!)  Leave me a comment or email me at kelli@ournewoldhouse.com.

First she finished up the last bit of scraping wallpaper in the front bedroom:

While she did that I helped Brandon take the air conditioner out of our bedroom window. (More on that in a little bit.) Next I helped Chantell scrub the walls to get the last of the wallpaper residue off and get them clean and prepped for plaster patching. There aren’t any pictures of me helping with this part, but I was there! She’ll vouch for me.

Look what a difference washing the wall made! The paint almost looks nice enough to leave alone! The spot in the middle has been scrubbed.

In this picture, the left wall has been scrubbed, the right wall has not. Like you needed me to tell you that anyway.

While Chantell and I were scrubbing, Brandon took the closet door off its hinges and took all the hardware off the woodwork so I can start stripping the paint. Apparently, when the previous owners put up a new style of curtains, they never removed the old hardware, just added more and more brackets, hooks, and screws as they went. So here’s the bag full of hardware he took off two windows:

Some of the brackets had been painted over multiple times. Here’s Brandon’s screwdriver and putty knife stuck behind one bracket:

He also took the register off the heat duct and removed the hardware from the door so I could put them into ammonia and soak the paint off.

When the previous owners were getting ready to put up the wallpaper, someone scratched some math problems on the wall in pencil.

Like I said before, Brandon and I also took the air conditioner out of our bedroom window. This project was a BEAST! First of all, the thing had been there for like 20 years. It weighs a ton. It leaked condensation all over the window sill, causing water damage to the wood and the plaster below. That will have to be repaired later. Our first challenge was undoing all the crappy insulating they had done all those years ago.

Brandon popped the front cover off so he could get a better grip. What a mess!

After wiggling it around a bit, we figured out it had to go out and not in, so we let go from the inside and let it sag dangerously off the side of the house.

There are no pictures of the next few steps because it took all three of us to get underneath it and haul it down to the ground. I’ll admit, we dropped it the last foot or so. I brought up the dolly and hauled it to the curb.

 We closed the storm window and I cleaned up the inside of the window as best I could.  The paint is all flaking off and the accumulation of dead bugs and cobwebs was disgusting.  But our bedroom is now just a little bit more insulated from the cold.

 Since it was really nice outside on Saturday I took the opportunity to spread some mulch around the back door to cover up the mud back there until we can get a new concrete slab poured.  While Brandon and I were working on that we found the coolest spider underneath a bag of mulch!   

It’s called a Woodlouse Hunter Spider and it only eats what are known around here as “roly-polies.” (They’re known in other places as woodlice, pillbugs, or armadillo bugs.) It’s perfectly harmless to humans, but sure doesn’t look harmless! I looked it up to be sure. I learned a lot about woodlice too! They live in damp places in the dirt and eat decaying plants and wood. You’ll find them under logs, in wood piles, and in this case, under bags of cedar mulch. They are also harmless to humans, but can indicate a dampness problem if they’re found near the foundation of your house. Like earthworms, they help enrich the soil.

EDIT: A kindly reader named Ron informed me that Woodlouse spiders are in fact dangerous sometimes because they are aggressive.  They’ll bite and the bite can be painful and nasty and all sorts of terrible things!  So don’t mess with them.  Thanks Ron!

Ok, moving on from backyard biology…

After we went down the street to Grandma’s and had a Mexican meal that couldn’t be beat, we came back home and I taught Chantell how to use the heat gun.

First, I made sure she was protected from the lead paint fumes.  That meant fitting, adjusting, and testing the respirator.  Hilarity ensued.

Then we got down to the serious business of stripping paint. Here Chantell waits eagerly while I plug in the heat gun.

Chantell listened carefully to instructions.

And watched me demonstrate.

Then I turned her loose!

She almost finished the whole door!

We did have some time to relax this weekend too. The cats got the whole futon to themselves while we were working.

Scratch didn’t mind sharing though.
