Thank you everyone!

Hello,

Stopped by a trailer house and found compressor won’t engage. High ohms across R and C. Old York so can’t read the data plate. How can I find out what size this is? Ran it the numbers...

Yes, this is helpful. The one we were using had more inputs (Psig, amp, volts...) so not sure if the outcome would be different since we mainly need the btu for this.

I tried the search function but didn’t find what I was looking for. I use to use an online calculator (it has been removed) that would give me about how many btu/h a system was performing at. Anyone...

I have 170k on my current f-150 work vehicle. Custom built rack with tank holding on one side and flatbed tool box on other side. Should be ready for a new vehicle in about 2-3 years at around...

This will show you the size difference and some other specs. Your HVAC company can do a Manual J, and D for you and pair the correct one(s) to your system.

I say either someone was just playing around with some extra thermostat wire and didn't care about their job or it is, as someone else suggested, a security wire to lock the unit down. I have seen...

Could it be from something making a nest in the exhaust such as a wasp nest? Does the exhaust slope to or away from the unit?

Good catch. I may have had a few drinks and was using voice to text and didn't double-check.

No trap installed but it is on the positive side of the system.

I think this company was onto something. Who cares about the 30 min it took me to clear the line and then tell the resident we have to replace the whole thing next week for X amount of $. I could...

An update. We Mostly finished. The last picture doesn't show the finished rock wall. We added a few extra layers to the corner. Now I am about to move out.... Decided I wanted a shop and I don't have...

Looks like, according to RHVAC9, I need 70cfm of fresh air. Could do with a 6" pipe but 7" might be better with all the turns. I'll put the questions to the inspector this week. Maybe they will let...

Looking into our MC I found PVC ductwork is only allowed below slab or in exhaust applications (though I was denied using pvc for bath exhaust a few years ago...). I may or may not be allowed an...

..... I've seen b-vent run through a return.... Best I know it is still as such (was denied repair)

That's what I thought at first. What happened is when someone put this condenser in the conduit wasn't long enough so they cut it (almost looks like the used the torch) and cut the ground at the same...

Ground screw has never been touched. Not sure how long it has been like this but whoever put this condenser on here did it like that.

Look at a horizontal discharge unit. Might give you more options.

Am I doing my math wrong or are you trying to cool you house to 65 degrees Fahrenheit?

75 (24) at 50% relative humidity is what you can expect on a design day (one of the normal hottest day of the...

You are talking about where the concrete wall meets the Seder shake siding? Yes, I plan on putting flashing on it. Not sure if I have the money yet. I am WAY over budget so I am starting to see a...

Not familiar with a drainage composite. Are you able to direct me to what you are referring to? I am using a heavier geotextile fabric to wrap around the gravel. Not sure if they are similar or not. ...

Nope. Actually hired my dad's friends step son to run the machine. Have to wait till tomorrow to finish. Crappy tires and the ground is still wet.

Started taking the dirt off the side. They did have some crappy drains put in (guessing 5-8 years ago) but they were clogged. Has a PVC pipe on top of footer but wasn't downhill so not doing much.

Probably would fly here. I could see it now... Man, putting this unit here will help keep the unit cooler and run more efficient with the vent sucking all the hot air away....

First thing, Buy a humidistat. If the humidity is high then you need to address that. More airflow from furnace or a dehumidifier.


I would have your airflow checked just in case... But, assuming...

The foam is for insulating mainly. Help with preventing condensation on the inside of the wall. It also provides a protection for the water proofing.

This topic has made some good conversation.

For clarification, on this specific house, the concrete wall in question is non-load bearing, is poured, is about 4" thick x 4-5' tall x 85' long. The...

Also, talk to someone about bringing the ductwork and furnace inside the home envelope and out of that attic.

I didn't read any of the post, sorry. But what I can tell you is that you need to 1) you need to have a load calculation done (manual j).
2) you need to have someone design your duct system for you...

A few questions:

1) is the basement fully underground
2) are the basement walls insulated on the inside, outside, both or not at all?
3) Are the floors (basement ceiling) insulated?
4) what do...

Nothing. I will daylight the French drain away from the house. The two gutters on the front will be run with solid PVC and daylighted near the French drain .

I was thinking 4" but two of the...

One more thing. I have about 90' worth for the French drain. How do I figure out how big of a perforated pipe I need? Supply houses here have only 3&4" I don't want to lay a 4" 90' long pipe and find...

Another slow update.

Thank you everyone for helping out. This house has been quite the project and leaning experience.

They built the house (all cedar mind you) below grade. After they were...

Since you posted... This house has two gas packs... Are your units compatible with a package unit or does a unit need to find a home inside the house and ducting go from there?

Why is it bad when connected to a significant amount of copper pipe? I don't disagree though that the galvanized needs to go. I'm hoping to start a French drain within the next month and I will do it...
