’Twas the night before Christmas, when blizzards and chills
Strain my budget by raising my energy bills;
All the stockings were swaying — a cold winter breeze
Made my home’s leaky envelope feel like Swiss cheese
(The old windows and ceilings have so many gaps
That the kids have to sleep in their kerchiefs and caps) —
When out on the lawn there arose such a clatter,
I sprang from the bed to see what was the matter.
Away to the window I flew like a flash,
And I yanked up the creaky old single-pane sash.
When, what to my wondering eyes should appear,
But an energy expert — a trained engineer!
The sign on his truck said, “We’ll fix your old home.
If you’ve got any cracks, we’ll fill them with foam!”
A bespectacled fellow came out of the van,
And asked if I needed an infrared scan.
“Lord have mercy!” I muttered. “I certainly do!
Any chance that you came with a blower door, too?”
“Yes I did!” said the man. “I’m an energy geek!
And I promise to find every defect and leak!”
And he whistled, and shouted, and leaned in the van,
While his helper unloaded a door-mounted fan.
“Get the Duct Blaster! Caulk gun! A bottle of Windex!
It’s time to reduce this home’s dismal HERS Index!
We’ll battle your dampness and foul condensation!
And make sure that your house has enough insulation!”
And then up to the attic the engineer flew,
With a cellulose hose and a spray foam gun, too.
And then, in a twinkling, I heard a strange sound
As the cellulose bales were chopped up and ground.
