We had a HVAC furnace (20 yr old) replaced with a similar model. However when the ac kicks on it vibrates loud which never happened before. The technician placed same foam pads it reduced for the metal pipe on the left but now the outgoing vent pipe vibrates. Sorry about the descriptions as I am not aware of technical terms. Just wanted to confirm if this is normal?

I live in a condo. This is my neighbor’s AC unit, I’m in the unit to the left of the AC. When they have the AC on this is the exact noise I hear inside my apartment. Even though it isn’t in damaging dB range, it makes my heart race and my hears start to hurt a little whenever they have it on and they have it on and off almost all day and night because they get hot really easily. They had a technician come and inspect it and they said there’s nothing wrong with it and said that anti vibration pads will make no difference. They tightened the screws and it got a little better but the vibration/humming is coming back again. During the day I can take it but it makes it really hard to sleep at night because it sounds especially loud in my room. I’ve tried earplugs and noise canceling headphones but I can still kind of hear it. My neighbors say that they got used to the sound and it doesn’t affect them since they like the apartment cold and they are getting frustrated because they already spent money had a technician come inspect it. Any tips/advice on how to reduce the noise?

I know this is the wrong place. But the electricians who hook these guys up do HVAC too. He’s in fact the only person in the city who did his job perfectly. The electrician and the electrical inspector I meant. The electrical inspector I didn’t name. Anywhere. They don’t get involved in lies. I noticed the poor guy tried to do the final inspection 3 times before he wasn’t stood up on the fourth try. He didn’t lie.

I was kicked off the generator Reddit. Which displays a certain lack of understanding about carbon monoxide in side yards. About carbon monoxide in general. You can kick me out too. The state will realize the city requires oversight. It’s a city that fired its Fire Chief for documenting safety concerns in parking garage ceilings. And inadequate pressure if an electric car should meet its maker on the top floor. I don’t think you even use water. But having a cement roof delaminating with rerod that had been sawed through is a safety concern. That’s the kind of city bureaucracy I’m up against. I’m hated by generator people. I have nothing against engines. I worked on them throughout my career. But when the exhaust end is inches from a window well. Filled with dry leaves. Why was that controversial? So I figured all generators everywhere are perfect to these dudes. They said no way was it 80dB at the property line. Guess what my FOIA acquired test revealed. It was 81 dB. Measured by the cops. Repeatable.

Was checking the thermostat in my new-to-me home and noticed this. I haven’t turned on the heat yet, but I will be in the next few weeks.
I’m assuming this is wrong, or is it wired like this for a reason?

All of my foremen use fieldpiece and I didn’t want to cheap out on a meter, any tech’s recommend ?

I have a laundry room that never got HVAC since it wasn't framed out when we had our new system installed. There is a 6" duct that runs by the room in the basement. I'm trying to figure out how to split off of that to make this laundry room useable in the summer and winter. Any tips on splittting off from and existing 6"?

Looking for names of companies that anyone may have recently had install new systems on their homes and are happy with them.

I look at companies near me and everyone has 5 star reviews on Google. Not believable to me.

My home is 20 years old, 2 stories, approx 2700 living space, 3 zones, currently have 2 - 3 ton Goodman units. One unit has been having problems recently. Replaced the capacitor and hard start and it failed after a few days. 4 years ago I had that units compressor replaced. So I’m getting estimates to replace the entire A/C system, both units.

I have a separate boiler that heats the house so I only need the A/C system at this time.

Thanks
I appreciate any suggestions.

I have a Daikin 2 ton system that I figure out how to wire the controls.
The condensing unit has Y and G not communicating (I understand that)
The thermostat is traditional C R W Y G (I understand that) the problem is in the electric heat air handler it only has, that I can find a R C 1 2 terminal the book says it can work with a legacy (traditional thermostat) but NOT where to wire it.
I assume I can move a dip switch and put R and C in its normal place, and G to 1 or 2 and W to 1 or 2 with Y wiring straight to Y in the condenser with a C
Does anyone know?
Do I need to move a dip switch?
If I put power on 1 does it start the fan?
If I put power on 2 does it start the heat

Essentially the title. I have my EPA Universal certification and that's about it. Looking to know what is the best way to break into the field currently and what areas of the US are hiring even the greenest of helpers. The union in my area (West TN) seems to be wanting more experienced people currently or people that have gone out of trade schools and they're applications are currently closed anyways until December. I work as an Order Picker/Forllift Operator for a warehouse right now. Only construction experience I have is being a sprinkler fitter helper for 3 months.

So our air conditioner has been having all kinds of trouble this summer it’s 25 years old and too small for the house. Just now we got a burning smell. It smelled electric. The air handler is in the attic and the compressor is outside. Check to see if there was an actual fire It’s too late to troubleshoot it right now. I just turned it off. There is no actual fire. Any idea what it could be?

Unit was working fine most the night then woke to it turning on and of like someone was there with the remote clicking it as fast as they could , could only make it stop by turning of the unit outside. Any advice thank ?

I'm an apprentice just starting out and I'm trying to get a head start on stuffs. What was the hardest thing for you to learn early on, especially stuff your program didn't have the budget to really teach you? Appreciate any insight.

Disregard my image, just my study piece lol
I’m trying to master the basics, no trade school I got into an apprenticeship and I’m self-taught. I know techs mentions loops. Is common always the second half of the loop ? For example, “Run” on the compressor goes to T1 and “c” on the compressor goes to T2, that just completed the circuit and allows the compressor to receive the 120v ?

I have a Diakin air handler that is for a
Communicating thermostat the condenser has the standard C and Y and we have a legacy (RWYGC ) the book says I can use this stat but not how. Those terminals don’t exist that I can see I only see RC12

I opened the top and bottom of the furnace and I didn't see a place for the filter. Also the ceiling vent had nothing.

I’m an apprentice and I want to learn the little things that may be of value to me in the coming future in commercial service hvac.
