HVAC has started, explanations and rough in!  

Make sure the HVAC guys run two drain lines all the way outside. That way if the main drain stops up, the secondary pan will still be able to drain. The secondary drain needs to be in a place that you can see. That way you'll see the water and know theirs a problem

You're a great educator. Thanks for going step by step and discussing potential problems/challenges. Very insightful.

I worked for my dad at his own company every summer since I was 15, now that I am 18 and graduated I am trying to re learn what I come knew, my memory isn’t very strong so it sucks right now. Hoping I will get this down.

Andrew, suggest you use a spread sheet or document format on your laptop to establish list of each breaker wire. Print the desired document and use clear laminating sheets. Tape sheet on inside door of your panel box. I just used numbers on each breaker that corresponded to the items on document. Breaker one may have one or more listed rooms, outlets, or whatever electrical supply line. Easy to update when changes are made. See you on Live Stream tonight.🙏

Andrew, I am very impressed with the decisions you've made with you A/C-Heating system. It's obvious you did your homework because you're extremely knowledgeable about this. You're a dedicated homeowner/builder/contractor working hard and making smart decisions. See you at the Live Stream and God Bless.

Hi Andrew very interesting video, we are always learning. You and Tiffany are going to have one beautiful home. See you guys tonight. 🇨🇦

Im happy the hvac has started for you. Its finally beginning to look like a house. 🤠

Hi, Andrew! Moving right along! Happy dance! See y’all later today.

I had Goodman...and never had a problem and ran very efficiently even in a 1972 built houses efficiency challenges

We have a goodman and it works fine here had it for several years..

8 years ago I had a Goodman unit put in at the lake house. I was not thrilled because it had all aluminum coils. The price was where needed to be so I went with it. Keep in mind we are not there daily. But I keep the AC on 82 when we are not there. When we are there I bump it down to 73. It has not given one bit of trouble. I have it serviced yearly and I have to admit I'm pleased

I’m catching up on your videos every now and then hurricane Ida really hit us hard. We got back power and internet thank God.

I work HVAC and Goodman units are good but they do use cheaper electrical components. This is not a big deal if you can test and replace parts. Here in Oklahoma we have to sleeve all wall penetrations, I use sch 40 pvc on my linesets. By code the last few feet should be flex when running hard pipe to prevent sound coming from the unit vibrations. Also if the unit is loud vibrating sound through the floor you can put vibration isolators under it the help. Great job you have chosen very wisely with your HVAC equipment. You will love the energy savings with the ERV but definitely plan on the cost of filter replacements. One thing to consider instead of a variable speed compressor because of cost is a dual speed compressor. That will give you some efficiencies of the variable at a much cheaper cost.

Wow, things are going fast, but I know you'll make the right decision on what to do. Me I'm thinking nap....lol God Bless

Enjoy your video's. Ive watched all of them. POA coming from a 25 year carpenter, Use either liquid flash from Huber or Lexal around your pipe penetration's. Lexal is clear and paintable. Ive used it in extreme cold(-35F all the way through 115F and it holds up. ) Good luck on your future build. Shoot me a message if you have any questions.

With your secondary drain pan, usually what's done is that a drain will be put on that pan as well, but the drain line itself will exit the house some place where it's noticeable. For example, ours exits right out the eaves of the back porch. This way if I see water dripping out from under the roof onto the back porch, I know that we have a problem with our main condensate pan and the unit needs attention.

I know this is an older video and you're well past this, but I wanted to comment. I'm glad you're doing multiple returns. I had a brand new home with a split system and 1 return. 2 story house, 2400 sq ft. And it was awful! After 2 years I finally made it somewhat comfortable utilizing vents and different settings, but the multiple returns will help you SO much! Secondly z don't fret too much about having a few flexible ducts in there. They are not as efficient, but it is what it is with this silly shortage now, and you have easy access to upgrade it later. They'll still last you a while especially with so many returns. This is from a simple homeowner, no certifications, but a really good understanding of how things work and fixing my own hvac and reading throughout the years. So gain of salt, but you're doing better than most.

I keep my bedroom at 62*F while I sleep (breathing issues) using a 12K BTU window unit...the power bill only went up $50/month average...in Mobile, AL (lots of humidity here too) :) The bedroom is pretty small...about the size of your pantry room...so it doesn't run much except on really hot nights in the middle of summer.

Just wanna chime in and say I'm loving it all,Kelly's country life rocks and thank you Tiffany and Andrew keep them vids coming 😀

Goodman is a good unit. I'm a home inspector and I see more of these with no issues than any other. We are thinking of mini splits in our 40x100 . With dehumidifier

Honestly, didn't understand a thing, but I am amazed how many data you know about everything:)))

Amazing! How on earth do you remember all the this first and that next? I got lost way before the end of the video. Keep up the exceptional work; you, Tiffany and Bullet are going to be very comfortable in your house.

Be sure to keep a close watch on the insulation on the suction line of the line set where it penetrates the house. The insulation commonly used on those does not have a long life span in the sunlight and will start to deteriorate. That would leave a gap in your penetration.

Love your trim plate for A/C lines. Never seen that done. Great idea.

HVAC has started!! Keep up the good work!

I'm in school right now. Could use all the tips I can.

I specified hard duct when I built. It is extremely noisy so I would recommend flex from the trunk line to the vent.

Flex is also good for noise reduction in the airflow. Plus in an attic it’ll never go bad.

Very interesting episode. I had no idea HVAC had become so technical.

can you show how you press in and smooth your calk bead? Thank you

I can tell you this, I had an air conditioner installed and they told me to get a 2 ton unit because of the humidity and you wanted the system running longer so it would take the humidity out of the air. The problem was it wouldn’t cool the house enough. Your house is definitely going to be better insulated but in my experience you should always go bigger. I did what the guy said and in the summer when it would be 105 out it would be 89 or 90 in the house. Then when we talked about upgrading because we only went with a 2 ton unit we would’ve had to buy a whole new blower furnace and everything but the ducting and we just had to live with it because we had already had it for six months but I’ve never gotten that hot yet. Make sure you get some kind of written warranty that if it doesn’t work they’re going to come and upgrade it without charging you for everything again. The guy told us that it said because of humidity you wanted your air conditioner running more and we had the air exchange and zones and that was 14 years ago and we paid $7600 for it which is probably twice that much now and we got screwed because we only got the 2 ton. If we had gotten a 3 ton we could’ve easily upgraded to as high as a 4 ton with all the same equipment. So make sure they give you a written guarantee before they install all of that because we got screwed big time and they told us the exact same story, that because of humidity you wanted a smaller unit that would run longer and take the humidity out of the air and it never worked As far as the brand most of the systems are made by the same companies, like carrier makes several different names and train make several different names and so on. But just be careful about that 2 ton thing because that’s what they told us. That system was separate from the main house and was only doing a little over 1000 ft.² and the 2 ton could never get it cool when it was over 100° outside.

3:30 its called a Fresh Air Ventilator or at least it's what they call it here in my states. Goodman AC units are good but it's all dependant on the factory. We had 4 goodman units no issues at all where as my AC guy stopped dealing with Goodman due to multiple defects they experienced which can happen to any manufacturer. I see some flex duct Andrew..lol You might want to press for metal to all rooms. I am living proof that metal is the only way to go after many homes with flex duct. If you remember the pics i emailed you. They should make an L trunk line and tap in each run from the trunk. Nice & Clean, Drain pan you will want metal with cleanout 12 inches high not level with pipe. 16:20 Float switch is perfect 17:00 thats some pro ac plumbing work bro! Ok for last part put a cement pad for the AC condenser something like a 6in and anchor the unit to the slab so you don't have to worry about weather related impacts.

FYI, you can add your own float switch and tie it to an indicator or alarm system. That way you're not going without AC for a day or so and wondering why.

you're right on ceiling up every penetration, you want to do all you can now before they get covered. isn't zip tape wonderfulit can take your fingerprints off.

The rectangle plate is a nice touch finishing off the a/c penetrations. 👍🏻

Appreciate the hard work and show brotha. I happen to work for a competitor of Honeywell but I think your decision is a good one. Obviously my decision would have been different but i see no problems with yours either. Thanks for the hard work!

I’m with you on the caulk thing. I’ve never lived in a house where I didn’t have to fix that because it was old and cracked. One time I had an ant trail going through there. They should really make grommets the pressure seal on there. Lol. The pipe sticking out of the top in the back look cool, it looks like exhaust tips from a car. Lol.

The secondary pan should be code, it is where I live in CT, also if you ever have a leak in that line set your paying big bucks to have a leak search done, other than that nice build!

Good stuff 👏 you may end up needing a whole house dehumidifier. Maybe

An additional consideration on the variable speed HVAC units is repair, both cost and parts. The fancier the system the more it requires OEM parts. If you live distant from a large city with multiple HVAC parts suppliers, you could end up with a long wait for the part to come in and the HVAC guy make that long run out to you again. Basic HVAC systems can be repaired with off-the-truck parts. ERVs are nice but the real thing is to separate cooling/heating from the dehumidification with a separate dehumidifier so you aren't balancing cooling with dehumidification.

There are some really good whole house thermostats now days. No reason you shouldn't be able to time program the bedroom zone and the house zone 7 days a week. Most are also app run so you can control them off site. You are going to have a really nice system.

Im theory the pipe running against the roof sounds great when it's wrapped in insulation, but it's a maintenance nightmare. You have to completely tear/cut out the insulation, fix pipe then re-insulate. I've did AC before I went to college, it's interesting work and I now have a top of line American standard, but definitely wish I had the zoning, maybe someday I'll get in the attic and do it!

Looking great:)

If you really want a tight seal on your house, there is a product that Matt Risinger first alerted me to on his channel. It's like this pressure based air spray mist caulking thing. I think its called a Caulk Misting Machine. Look for his video on that. It seals holes or gaps in your house that you not only could not get due to the limits of the laws of physics but you would not even be able to find them. Like an extra wide opening in a screw or nail hole or a space between two boards caused by one of them bowing or something else.

Goodman!😱. As a realtor we see tons of issues with these systems. Builders put them in because they are generally less expensive than anything else. I hope you have great luck with yours as I’m sure you did your homework but it scares me a bit based on my experience with them

I guess its only in my area here in Missouri, but did you consider installing an attic fan? I use ours a lot during the spring and fall when the weather is cooler and can avoid using the AC at all. I use it a lot even during the summer in the evenings. I love it for when I'm cooking or want to just clean the air out of the house quickly. (Like when my teenager burns something while trying to cook. lol)

Exciting stuff happening! I like the way you think. OCD or not, it's a good feeling to get things done they way you believe is best. This seems like an awful lot to keep organized in your mind. Do you feel like you're juggling 20 chainsaws? 😀

Great video....very informative.

sealed house is good. those who do not seal well have no control. sealed you can open or close windows - your choice.

Do you look at multi zone mini split heat pumps? That’s what I’m thinking about going with. Along with a ERV for air exchange z

When do the windows get installed? Looking great.

Should’ve done amana s

Andrew you said the ERV was plumbed into the hvac so how is it going to run when it needs to if the ac is off , I have been researching and they say in a humid area that it should be plumbed separate

I would ditch the caulk and use silicone

Great video. Would you happen to the know the model /brand / any info of those ceiling registers ?

In the bedroom i was very surprised to see a return on the outside wall and the return in the inside wall. On top of that the thermostat is under the supply. Also how does zoning a 2 story house with a single stage unit working out?

Haven’t seen any plumbing videos have you done all the plumbing lines to sinks and shower and out side connections. What type of hot water heater are you going to use tankless gas or electric?

I would've ran my condensation drain into a drain in your in the waste water system if allowable. It's gonna be a constant wet spot in your yard while the a/c is in use.

Andrew, you should have went for a 3 ton unit, regardless of what the engineers say. I have a 26x44 house that sits in day sun with no trees with a 2.5 ton unit, it runs more than it should. I had a Goodman unit when I had the house was built, always had trouble with it & it never turned off in the summer. Have a Carrier 2.5 ton now, it was borderline about going with a 3 ton when we changed units. i should have went with the 3 ton bc it was only about $300 more. The front of my house gets day sun all day & I have a black roof & 5 windows & a door in the sun. I have an outer thick glass storm door, I have wilted a plastic Christmas wreath between the doors during December & it fairly cool here in upstate SC that time of year.

are you going to make it to keep the pantry at a certain temp for food

What about the openings in the attic? Don't you have to close them before spray foaming?

Need a label maker, for wire

Put a “stack” on a tee for the evaporator drain with just lose cap on it. Every few months pour some bleach down it and you’ll never have to worry about clogs due to bugs, mold etc. Make sure it is after the condenser drain with enough slope so that it will not back flow onto the metal of the evaporator drain pan. The catch pan the whole unit is in should be your absolute last resort.

So can we install a window unit in our room 🙄🤞🏽

You are ending up with what could be a construction demo house.

Would it affect the requirement of having to do that efficiency study if you had a complete solar setup that had you drawing nothing from the grid?

How will you heat your home if you need to thru the same unit as your AC

What is your projected recovery time from night settings to daytime settings in zone 1?

What’s the future power consumption of your current AC unit versus one of the variable speed ones. Pool pumps are insane they’ll pay for themselves in the first year on your electric bill if you do the variable speed model. The lower speeds are so much less wattage.

Omg Goodman is the worst system you could buy. We use to sell them to customers on an extremely low budget. We had so many call backs and so many evaporator coils leaking in less than a year that we decided to no longer sell them as our economy system. At a minimum we sell Rheem as our economy system now. Andrew you are going to regret this decision.

Let me get this straight they limit the size of your AC by code? So you couldn’t put in a 5 ton?

What's your height at the peak of your building?

It kills me to see these homeowner contractor videos,electricians are last of the subs to roughin

👍💞

t stat should be by return!!!!!

What size were those lines?
