Your house, finally understood.

Nobody hands you the part where you learn which noise matters, which month is hard on a furnace, and what the last owner never got around to. Keephouse is that part.

Hear when it ships

Sixty seconds in

A calendar for your house, not for houses.

An address and four questions — year built, how it’s heated, roof age if you know it, crawlspace or slab — are enough to lay out twelve months of what a house like yours needs, and when.

Every line of it starts as a guess, and is labelled one. We would rather tell you what we don’t know about your house than pretend the calendar arrived complete.

KEEPHOUSE
1417 PINECREST ROAD · BUILT 1994
Here’s what we think your house needs.
All of it is a guess, drawn from county records for a house like yours. You’ll correct us as we go.
AUGUST
Change the HVAC filter
Four minutes · you can do this one
GUESS
Clear the dryer vent
Twenty minutes · this is the fire one
SEPTEMBER
Flush the water heater
We think it’s gas, and from 2011
GUESS
OCTOBER
Clean the gutters
Before the oaks drop, not after
Take the walkthrough
Ten minutes, six photos, and we stop guessing.

Record
The calendar, the first time you open it.

Then you teach it

Point the camera at the label.

The furnace has a model number on a sticker inside the front panel. Photograph it and the guess about your furnace becomes a fact — make, model, fuel — and the filter size, the service interval and the price range all follow from it.

Six photographs around the house cover most of what the calendar was guessing at. Stop anywhere; it remembers where you were.

The photograph isn’t kept. It’s read once, in memory, and thrown away — there’s no bucket of pictures of the inside of your house, because there’s nothing to put in it. What stays is the line of text it produced.

Changing it
ABOUT 4 MINUTES
1
Set the thermostat to Off. Not Fan. Off.
2
Find the slot on the return duct — the wide sheet-metal box on the furnace’s side.
3
Look at the arrow printed on the old filter’s edge. The new one points the same way — toward the furnace.
4
Slide the old one out, the new one in. Nothing latches or snaps.
Buy the same size, not the same brand. Brand genuinely doesn’t matter here, whatever the box says.

And it knows where to stop

Some of it we won’t walk you through.

Gas, the electrical panel, the roof, anything structural — the app explains what’s happening and why, gives an honest price range, links the manufacturer’s own manual rather than a rewrite of it, and tells you what to ask for on the phone. Then it stops.

That line is a lookup table, not a judgement the software makes in the moment.

GAS WATER HEATER
This one we won’t walk you through.
That rumbling is sediment on the tank floor boiling under the burner. It’s extremely common in hard water, and it is not an emergency tonight.
We don’t write instructions for anything involving gas. Not because it’s beyond you — because a wrong step here is a carbon monoxide problem, and no app should be the last thing standing between you and that.
WHAT IT SHOULD COST
Flush and inspect
$150–$250
Full replacement
$1,400–$2,200
Yours is fourteen years old. These typically last eight to twelve.

WHAT TO ASK FOR WHEN YOU CALL
“A tank flush, and tell me the condition of the anode rod.” If they can’t answer the second part, call someone else.

It isn’t finished yet.

Keephouse is being built now, for iPhone first. Leave an address and you’ll hear when there’s something to install. That’s the only thing the list is for.

No newsletter, no launch countdown. One email, when there’s a build.
