Roof Valley Aimed at HVAC Condenser
Posted on 7/13/21 at 3:04 pm
Posted on 7/13/21 at 3:04 pm
I moved into this place in September and I'm not sure why this house has this design but one roof valley is aimed directly at my condenser unit outside. I had never really noticed it before but water slams against the blades and slows it down, which obviously isn't ideal.
I don't have gutters but I imagine there's something small I can add to the corner to redirect the water elsewhere.
Any suggestions are welcome. TIA

Gutter with deflection plate is one possible option

your concerns are warranted, water pouring on it constantly will cause the fan motor to fail earlier then normal and make extra rust then normal. it often creates holes in your yard as well where it constantly beats the ground
they have deflectors for valleys, its just a damn at the roof edge to stop the torrent of water so it deflects left and right but it will still be draining within a foot or two of what it does now.
if it were me i would install a drain pipe there to direct the water to the ground and then outward

get gutters.
Been spending a ton of money lately and not really ready to commit to this. But I agree it will be done eventually.
Any links to diverters or anything is appreciated. I don’t like doing roof work because I’m always worried I’ll cause a leak so any direction is also appreciated.

You can get just that one section done first and it should be pretty cheap.

Get you a 10' section and do it yourself. Send 5' each direction without a cap and let it shoot away from the unit.
Also, make sure to post a pic.
Seriously, it's just a thoughtless design by the house planner and guttering or an awning over the unit is your only recourse.
Speaking of awning, what is the wall finish?

Here’s what I’m working with. Genius right?

Doesn't look like the valley is dumping much more water on the unit than would come from the roof without a valley.
You could always "scoot" it over closer to the window if you deemed it necessary.

Trust me, it gets much more rain than it would from just being along the roofline. With the heavy rain today I could hear the fan bog down, speed up, then bog down again. Obviously I would prefer it be out in the open or further under the eave but I'll deal with it as is if I can.

It's on a concrete pad and I don't want to risk overbending the copper refrigerant lines going to it.
One of my buddy's suggested this device:

And in the reviews you can see one guy actually turned it at 45 degrees in a valley to prevent exactly what is going on with mine. For $50ish, I think I'll give it a try.

Dear engineer

A downspout down the wall by the fence, corner piece and short gutter work...get the stuff at a big box store and knock that out yourself for...what?...$80.
It's what I would do until you can add real gutters.

The water coming down the valley is likely shooting out to far for rain handlers to catch. I tied them, wasn’t impressed. I now have gutters and they work great. Get the leaf guards for the gutters too

I'm not sure about that. Up here in midwest, it is highly desirable to keep the condensing unit in some type of corner because it provides a lot of protection from hail. Also, it can provide a lot of shade for the unit which helps increase the efficiency and output levels of the unit. So naturally, this means a lot of outside units end up right under the valley of a roof. But you will rarely find a house w/out gutters up here so it isn't an issue.

I've always found that gutters are surprisingly cheap given how much benefit they provide. Even using a professional, most homes can be done well below $4K. Unless your property has fantastic slope, I cannot imagine not having gutters.
My first thought for a temp solution was to build a sloped roof over the unit, similar to what the other poster showed.

buy the time you factor in materials and the ghetto fab look, just buy one run of damn gutters and spout.

i was doing a/c work for 35 years and no way in hell would i have allowed a unit installed that way not even considering the roof drainage.
a unit requires 12" of free air space around it on all side for proper cooling and yours is being suffocated so close to the wall.
have the a/c guy reposition it so you have good airflow on all sides and this also gives you the opion to relocate it to a better spot. i relocated units all tyhe time its not that hard to do and its not that expensive to get done

i see shite like this all the time when i come out to install a new compressor that burned up from over heating.
a/c units require 3ft of clear unobstructed free air space above the exhaust fan to prevent recirculation of heat and causing the unit to overheat and shorten its life span
A FEW RULES FOR DUMMIES THAT PEOPLE NEED TO HEAR
-DO NOT BUILD A ROOF OVER YOUR UNIT
-DO NOT LAY SCREENS OVER YOUR UNIT TO USE IT FOR DRYING PEPPERS AND WHAT NOT
-DO NOT ALLOW WEEDS TO GROW ALL UP INTO YOUR UNIT
-DO NOT LET THE MOWER THROW GRASS ON YOUR UNIT WHEN CUTTING GRASS
