Heating and air conditioning the attic

We had central air installed at the end of last month and a couple weeks ago we had a duct run up to the attic so we can use that room comfortably year round.

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

Big Day at Our New Old House!

Brandon thought he was getting a day off when his flex schedule worked out that he didn’t have to go in to work today.  I fixed that in a hurry!

At 8:00 this morning, the storm window company, Corn Belt Aluminum, began removing our old storm windows and installing our new attic windows. 

At noon, Joe Kemple is coming over to tune the piano.

Sometime between noon and 4pm MidAmerican Energy is sending someone over to check our gas meter.

At 4pm Brandon is taking the car in for some work on the tinting. 

Kinda makes my day at the day job seem boring. 

I’ll have pictures of the storm windows when I get home this afternoon.  I’m so excited!!!

MidAmerican Energy Audit

Last week I had a visit from an energy efficiency specialist from our local energy company, MidAmerican. MidAmerican has a program called EnergyAdvantage: Save Some Green. Homeowners who get their electricity and natural gas from MidAmerican can call for an hour long appointment in which a specialist will walk through your home with you, take notes on the current state of your home’s insulation and energy usage, and then make suggestions on how to improve the energy efficiency.

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.

Storm windows are ready!

Got a call this morning that the storm windows are ready!  They’re going to wait for the sun to come out a bit and then schedule the installation.  Also the two replacement windows for the attic are ready.  I can’t wait to get them all installed!
