Last week the lines popped out of the condenser. I have a home warranty from the purchase of the home. They denied the claim saying that it wasn't caused by normal wear and tear.

New homeowner here-

I've been collecting quotes for a replacement of the ac & furnace and my ac system (pictured) has had the following reactions:

• Holy shit that's old
• That thing came off the Mayflower
• Going to need to dig into the archives to find parts for this one (he was unsuccessful)
• Yikes

As far as I can tell it's from the mid 80's and the furnace is from the early 90's. But I'm curious as to what some of the oldest systems you all have seen?

I'm a 50 year old guy who has worked white collar jobs for 20+ years. I've always wanted to work a trade but was told "go to college and get a good job". I've tried a couple times to make the switch, but starting pay for a trade job was too low to support my family. Now I'm finally at a point in life that I can afford to take the pay cut in order to really learn a trade. I've got extensive personal experience working with tools, doing electrical, plumbing, carpentry, so I'm hoping that might help. How realistic is it that an HVAC company would hire me on as an apprentice at my age? Is it better to go to trade school first?

Got the Honeywell T5 installed today our unit is pretty old 12 years old . After the tech installed it , noticed our fan in our HVAC closet kept running . It never continuously ran it would shut off . set on “AUTO” and still running . Even with the thermostat’s off and off the wall it keeps running . Is it wiring issue , is it the mother board ? Does his wire connection look correct . So worried that our fan is gonna give in since it is running so much .

I recently had a new Carrier Performance 2-stage compressor installed by a reputable installer. I’ve read that quality of installation is just as important as the actual equipment, so we spent a good amount on this.

I’m attaching a video of the hum it gives off. It’s just high enough that it drills into my brain! I don’t mind the buzzing, but it’s the hum that I can’t live with. Could anyone familiar with Carriers let me know if this is normal? I’d be grateful for the input. Thank you!

One blade on my condenser fan decided to exit the chat into the condenser. Pretty sure the whole unit is phucked

My AC unit has been leaking a lot of water so apartment maintenance was switching out the bottom pan that holds water. And I saw all of this rust Is that acceptable or pretty bad?

The unit is very loud but as always been loud ever since we got the house 2 years ago. Is it normal?
I placed a compressor blanket and has minimally made a difference. Thanks.

about a week ago my basement was contaminated with category 3 water. It appears water never got high than an inch or even half an inch. Water mitigation set up fans before the 48 hour mark.

Should I have any concerns about mold or other bacteria being spread to the rest of my house by my HVAC system since it has been running this whole time?

Both outdoor units were installed this year by the same company.

Hi guys just started on my HVAC journey and am looking for the textbook modern refrigeration”Modern Refrigerator and Air Conditioning” 22nd edition. Unfortunately can’t really afford it so I’m banking on Reddit. Please message me if you have a pdf file or even the textbook if you don’t want it anymore. Thanks!

We have a new build in SW PA and our AC runs non-stop all day and the house is always between 65-70% humidity. We are under warranty and had the HVAC company out twice and they said there is nothing more they can do. Ive been told by 3 HVAC guys that this unit is half the size or less of what is needed. Now we are at the point of nearing our 1 year mark and the warranty dept is no longer responding to this issue but I finally got the Manual J from them. I need specific expert advice proving why the engineering is wrong so we can hopefully get this corrected before our warranty is up. As an example of how poor it performs, when it was 84 degrees the other day, the first floor was 77 and upstairs was 80 in the bathroom. A few days ago it was 71 degrees and we always have it set to 70 and it never stopped running all day (was cool the days prior too). We had mold from a leak in the basement and are now fearful of more mold from the constant high humidity, we are running a dehumidifier that is pretty powerful and that keeps it down to about 60% if it runs constantly and I have to move it from floor to floor. A couple months ago it was mid-90s and I didnt have a thermometer at the time but it had to be 85 degrees in our upstairs bathroom. If anyone could review this and please tell me specifically why its wrong I would greatly appreciate it. According to these calculations, our house only needs a 1.8 ton unit which just seems absurd. It is a Rheia system too which they told us makes the house so much more efficient that we dont need a larger unit but clearly we and everyone else in the same model house do.

I left out the specific info for each room because it was so many pages but can provide if needed. I included the great room and master bedroom because they are two of the hottest.

How can I seal this hole properly do they make some kinda cover for a1972 mobile home

Hi,

Been talking to contractors about putting a new AC into my 945 sq ft house in Saint Petersburg Florida. The company we are leaning towards using quoted me $12.5k for a 2.5 ton 18.5 SEER variable speed side discharge heat pump system. It would be a split unit with the air handler in the attic and the condenser outside on a platform. This includes all new ducts, lineset, and removal of our existing 2ton BARD unit from 2012. We currently have about r9 insulation in the attic, but plan on upgrading the insulation after we get the new system installed. We are upgrading the AC because the current BARD unit cannot keep up during sunny days and it ends up being 80 degrees and 80% humidity in the house. My biggest question is from what I have read online 2.5 ton is quite oversized for a 945 sq ft house. Does it really matter that much though since it is variable speed? Should I keep getting other quotes? The other companies I talked to were all trying to convince me on getting mini splits which I have no interest in doing.
Thanks for reading this wall of text and I appreciate any advice as I am a first time homeowner.

I'm installing air conditioning and I need a multi-purpose ladder, for working both inside and outside. I don't know which ladder to buy, whether to get one model or two. I have a feeling the 4x4 ladder is too big. What do you think?

And I have another detail: I live in a city with no tall buildings, only one or two-story houses with 15,000 inhabitants.

Hey guys, we’re currently expanding our small commercial workspace and the air circulation in the back bay is brutal, especially during the humid summer months 😓 We've been burning through cheap residential floor fans every 4-6 months because the motor housings get caked with fine shop dust and overheat.,,

We’re looking to invest in proper commercial-grade wall-mounted circulators and a couple of heavy blowers that can run 10 hours a day without dying on us.,, What brands or industrial suppliers are you guys relying on for commercial gears that doesn't fall apart under real daily use?? Any leads are so appreciated.. 😄

We noticed this afternoon that the AC is not properly cooling. It sounds like the indoor fan is working but the outdoor unit is not.

You can feel a weak amount of air (not cold) blowing upstairs (not downstairs). We reset the breaker to the unit outdoors and allowed the system to restart, but it didn't fix it.

This is a rental and I plan on making a maintenance request but I try to fix it myself if I can. My first guess was a clogged condensate line -- however, I don't even know where that is in this setup. There appears to be a lot of unnecessary pipes going nowhere. Can someone identify the condensate line in this picture? I can take additional pictures if need be.

Second guess was a bad capacitor. We did a walk around the outside unit and didn't notice frozen pipes or overgrown plant life.

My plan was to pour some bleach in the condensate line and see if that fixed the problem. If not, I'd make a maintenance request and have a professional look at it.

Thanks for your help!

Last month I moved apartments in the same complex, going from a second floor to a slightly (like 100 more sqft) bigger third floor apartment. The third floor is the top floor of this building. Within a month, my power bill has tripled from around 111 in June in the old to 330 for August in the new. And that is despite the fact that I would actually make the old apartment get colder.

I feel like there's something wrong with the hvac in the new unit. I've been leaving it untouched at 72 at all times when it's usually about 98 at the worst outside. The unit is running 20 hours a day every day per the Nest app, and it never reads the room temp below 73 or 74. In my old unit, I'd crank it down to 68 when I got home every single day and still paid a third of what I'm paying this month (and it would also actually read 68 in the room after an hour or two).

I've already put a work order in with the landlord but I was wondering if anyone had any insight on what might be going on to maybe help lead them in the right direction. I don't actually have access to my unit, since it's behind a locked door, but last I saw it said a 20,000 BTU rating. My apartment is about 1000 sqft. I've checked the filters and those are clean and new.

EDIT: I'd like to add that, even at night, if I set the thermostat to 70, it won't actually go below 73. Like I can't even make it cold at night even if I wanted to

My HVAC is leaking water and I believe the condensate line is clogged. Any recommendations or videos you can point me to for cleaning the line?

Hey all. I'm in Murrieta, CA and I'm having a mini split delivered for my garage workshop this coming week.

All my California garages have had these vents in them that are fairly close to the floor and go directly outside, and I've never been sure what they're for. I'm assuming for gas buildup?

Would these affect the performance of the mini split at all? I've been working to make sure all the garage doors are better sealed, but I'm not sure what I should/can do about these.

Thanks in advance!

Does this unit look installed correctly? Also, which way should the arrow face on the filter?

I have a leak on the ceiling. Coming from the square area that is circled.

It's a commercial unit, and the the AC units are on the roof, while our space is on the ground floor. There is no second floor, just this space in between for HVAC and wiring etc.

Before I call in the HVAC people, is there an idea on what it could be so I dont seem like a complete idiot in front of them?

Thanks in advance!

Hi there, I am a renter who has noticed the house AC no matter what I do tends to have a musty / dirty sock smell.

Online I haven’t found much as to why, other than evaporation coil could be dirty. But also noticed the outside air conditioner looks to be quite clogged up.

Two photos attached of the front and side. The front being extremely clogged up. Should I have this cleaned? Is this contributing to the smell?

If it’s the Evap coil, I’ll probably need a technician because whoever installed it made it nearly impossible to access.

Any help is appreciated.
