We ran across this on a home energy audit. Needless to say we stressed the importance of new equipment not only to get this just out but to install new plenum and return drop. Static pressure is 1.0 furnace and ac oversized 80K and 3 ton ac that doesn't work for a 1200 sq ft home. The homeowner actually said a business installed this which I could not believe I thought this was side job bob all the way. Hopefully she lets us turn this turd into a work of art.

Hmm, let's see:

- No trap on AC drain
- Flexible appliance gas connector not allowed, can't penetrate cabinet with it, and no bushing or protection.
- black iron gas line crooked
- re-used ancient gas shutoff and union
- plenum horribly made, and it looks like the front and side panels are aluminum not steel
- line voltage across top of furnace and down side with no clamps (and why didn't they just go in the left side?)
- low voltage not properly strapped/secured
- low voltage splice exposed

What's that flex duct coming off the return? It looks like it's just hanging down.

What a beautiful job.

Yeah it is always a goodman lol. I know I don't know why they decided to run a 6' greenfield across front of furnace instead of going in left side. My guess what they bought a pre made whip from depot and didn't have the tools to cut it down. The flex duct laying down was a fresh air make up. We replaced that with 4" insulated flex and performed a duct cleaning. I didn't want to touch the furnace but I don't write the checks. Homeowner spent $6000 in insulation supposably getting new system from us in a couple yrs. I'll believe it when I see it.
 
Actually the fuse disconnect switch is still sold in my area and is used on the really low budget installs.
Thats something I never fully understood.

Code requires a switch at the unit, and a properly sized breaker at the panel.

Adding a fuse at the unit, seems it gains nothing, and adds cost.
Something I'm missing?
Not having to change out an incorrect breaker?

What's wrong with that? All the landlords have it installed that way.:angel:

where iam from you HAVE to have a disconnect at the unit if the braker panel is NOT with in 30 feet direct line of sight.
i install them as an added protection device .

I worked on a commercial setting that did the following, all legal: there was a 100 amp 208v circuit breaker feeding a set of 7 condensers, each between 3-5 ton. Each disconnect had fuses and they all ran off the same breaker.

You could put a breaker outside, but it would be more expensive and it would have to be outdoor rated. Fuses are cheaper.
