That's a thing you could have done, cover their window with your AC unit? It seems like something that planning regulations should prevent. And still, they have a loud compressor right next to their window.
This has four-times given me immense negotiating leverage, with the trade-off of having to provide my own labor for minimal standards of living (e.g. I currently pay ~40% below-market, but am responsible for all HVAC/mech/pest maintenance; example: recently replaced the water heater).
Have you asked your landlord if you can modify your apartment, or is it a corporate no-returned-calls situation?
Obviously having family in South America where there are millions of these installed by unskilled labor I decided to DIY. So I installed 2 units with 2 heads each, including pouring the concrete pads, vacuuming the line sets, and charging them. Took me two weekends and about $4000 in materials including the units themselves. It’s been two years, none of the BS fear mongering issues have happened, and they have almost paid for themselves.
You do have to go through the permitting process which means having someone come out to view it and write off on it and if you state it properly it should be less than $200.
Managing the lineset is the scary part (though it's not that hard). You're vacuuming copper lines that you've hopefully sealed correctly. If you get that wrong and your refrigerant yeets off into the sky, you have to call in help because it's hard for an unlicensed person to get the refrigerant legally. That half-hour of work and ~$1 of materials will cost you a punitive amount of money.
Ten years ago, I downloaded a free study guide and took the test in-person at an A/C supply shop for about $50.
Today, you can take the test online.
The actual work involved is relatively easy and straightforward. However, the code and regulations are extremely difficult to navigate. There’s a lot of non-obvious things you have to do to be code-compliant.
Similar thing happened for Veterinary care clinics.

You call for one broken outlet and they pull out fancy branded folders and pens with checklists of every little thing that could possibly be upgraded (inplying its needed for safety) present you with a multi $K bill and then do a little magic 10% discount for some reason to make you think its a good deal.
That said I get my petty revenge by asking questions at the free consult (marketing opportunity) then hiring local guys instead, whenever I cam find them.
This sounds very strange to me. I installed ACs on all three floors in my house in a day. (Not in the US)
NYC is a famously difficult place to have work like this done, especially in a shared-ownership building like a condo. You need your neighbors to agree its okay to do, your board/management company needs to review and be satisfied with the insurance your contractors carry, the city has requirements for electrical that always require permits and often require a master electrician to do the work, and even once the work starts the walls and spaces you're working in aren't exclusively yours and your contractors will be discovering things along the way... plumbing for that spigot you didn't know your neighbor had on their terrace, roof drains, etc.
The process of just getting approval to do work can vary from "chill but time consuming" in small buildings to "impenetrable bureaucracy so don't bother if you're not using the approved vendors" in large co-ops. Once it starts, that master electrician you hired to run the 220v service isn't gonna waste his time repairing drywall, a cheaper subcontractor will do that, and the latency just cranks up from there
I love city living and understand that most of these rules and regulations exist because bad things happened when they didn't - frankly I wouldn't trust most of my neighbors in buildings I've lived in to do their own electrical work or pierce the building's envelope for any reason - but also sort of understand where the outsider's perception that city homeowner life is hard and expensive comes from. It very often is, by comparison.
This article is a perfect example of why I moved out of NYC. Contractors there are more likely to be dishonest, less skilled and more expensive and have insane leverage over rich apartment dwellers who might own a screwdriver but basically have no ability (or permission) to do anything themselves.
Smart, productive people thus have large parts of their lives eaten up dealing with things that are trivial in a large majority of the country because of the density. I decided I’d rather spend my time pursuing my own goals not basic daily comfort.
Take a look at Sensibo. I have one and I'm pretty happy about it.
I say that even though I live in a historic house that I’d hate to see go away.
That said, I’ve spent a fortune bringing it up to modern energy efficiency standards.
The compressor would come on for a few seconds then shut off.
After 2 different HVAC companies quoted me $275 to come out (plus hourly and the repair once they find the issue) and then also told me it would be 10 days before they had availability I finally bit the bullet, bought a $30 multimeter, watched a few videos on how capacitor failure is super common and how to hopefully not kill myself, and after confirming with the multimeter and buying the $7 capacitor everything was right back to working with 2 minutes of work.
I did have a moment where I dreaded thinking I'd need to replace the unit and if so whether I'd want a split put in but for $53K I'd better get a third job... Quite glad not to have had to get too far down this road.
When they came back to check the system for a full quote, the tech felt so bad that they just installed the new capacitor for free and we got another few years out of that boiler.
A quick web search indicates that nyc $/kwh is about 31c. So that’s 3225kwh in one month! My standalone house plus pool pump, dual zone ac, and ev charger doesn’t even come close. Clearly there is a major insulation issue which is the root cause and everything else is just trying to put bandaids on an arterial bleed.
They have terrible insulation.
> We do have bad aluminum-framed windows, and we also have no insulation in our ceiling, so maybe all the heat goes to our upstairs neighbors. I also have various fans sucking air out of the apartment non-stop, one in each bathroom and one from the clothes dryer (when I hold an incense stick up to it I can see it pulling in air even when it’s not running), plus I have an elevator that opens into the apartment which might have a chimney effect.
They not only have zero insulation, they have negative insulation. They would have saved more money/energy by simply stopping all the heat/cold loss. And (at least in my state) they'd still get rebates for installing new insulation.
I have a three bed circa 1897 coop in Brooklyn. We have the leakiest windows this side of the Mississippi with multiple in-window air conditioners and my bill never goes above $450 in the summer (that’s probably about 250-300 in comparable usage for the middle of the country).
$1,000/month to heat a 3br apartment? Holy crap is he keeping it at sauna temperatures? The most I've ever spent on my poorly-insulated 1960's era bilevel house is about $250.
I lived in an apartment where the floor was poorly insulated. When a new neighbor moved in downstairs that heated their bedroom more aggressively at night, my heating bill went down because the heat rising from below made it less necessary to run my own heating as hard.
It might also be the difference in electricity cost. Especially with tiered rates, you can easily find yourself moving into a higher tier where every kW is significantly more expensive than in the previous tiers. PG&E in the SF Bay Area charges between 43 and 60c/kWh. A 2kW heater is going to cost about $1/hr to run , so if you're working from home, have little kids it gets expensive quick. And in the middle of a NY winter, with a poorly isolated apartment, you might well be running the heat in some capacity pretty much 24/7.
They may also keep the heat higher than most people. There's mention of an au pair so there must be a small child.
Ever spend time in a hotel room with a noisy, rattly AC that turned on and off all the time because it couldn't maintain the temperatures at the set point? Hard to get decent sleep.
It confirms three things for me.
1. Contractor quality is the biggest pain for the adoption of residential green tech.
2. Old homes (if not historic) should get depreciated aggressively by the market to the point that knock downs make sense. Japan does this.
3. DIY is has the hidden benefit of speed/quality/cost, since contractor pain is high. Yes, I understand the massive opportunity costs.
A friend of mine is trying to install a new central heat pump in their home. The only thing stopping them is contractors being hard to work with. Not price.
Here’s my DIY install.
If I remember correctly, I think I found a link from the actual Mitsubishi website linking to it
A Google search on the hostname does return entries for Mitsubishi, DNS points to AWS.
I might be misunderstanding something
This site can’t be reached
Check if there is a typo in mylinkdrive.com.
DNS_PROBE_FINISHED_NXDOMAINhttps://dnschecker.org/#A/mylinkdrive.com gives similar results - resolves fine in North America (US/Canada/Mexico) and a few other counties (Brazil/Ireland/Russia/China, and one of the two Australia sites), but fails elsewhere (including in Singapore).
Geoblocking seems like a possibility.
There is huge gap in the market for tradespeople who take their work even semi-seriously.
I just hate, hate, cannot stand paying skilled craftsman hourly rates for rushed sloppy work.
I’ve opened up my hood a few too many times to find a cap or extra bolts tucked in between the side of the hood and the weatherstrip.
Are duplicates from the new part? Did they assemble it and find they had extra fasteners (I know I have)?
Did they puncture my seat while they were in the car and then gaslight me?
I could go raise hell, but it’s difficult to prove these things and the mechanics I trusted have moved on to better careers in HVAC or elsewhere, so I just put on a podcast and do most of the work myself. It’s not so bad.
I’ve bought new 3 times now with this strategy and while I could buy used and save some money or drive them longer, I view this as the cost of avoiding major maintenance.
Anytime I’ve owned a German or American made vehicle the chance of something failing is too high for me. The entire experience of having a vehicle out of commission is a huge hassle I want to avoid altogether.
Against better judgement, I do also own a Tahoe that I bought used just for doing “work”. Towing and doing dirty stuff, Home Depot runs, etc. It’s basically a tool for the DIY stuff I enjoy doing (house construction/work). It’s caused me the most grief, but still not too bad, belts and radiators and alternators, stuff I’ve diy’d because it’s easy but still stuff I’ve never had issues with on Japanese cars.
- Trade licensing fees
- Liability insurance
- Medical insurance
- A vehicle to move equipment around
- Vehicle insurance
- Tools to complete the job
- The time taken to drive to your residence
- The time taken for the quote itself
- The expertise required to correctly spec/quote equipment
- The tradesperson driving to the city office
- The tradesperson applying AND paying for a city permit to do the work
- The tradesperson driving to a supply house
- Purchasing the equipment on credit
- Transporting the equipment back to your house
- Ripping out and disposing the old equipment (if applicable)
- The time and expertise to install the equipment correctly
- The time vacuum out the lineset
- The time charge the equipment properly with refrigerant
- The time commission the system and make sure it's running properly
- The tradesperson driving BACK to the customer house to be present for a city inspection
All those big ticket items you mentioned are meant to provide shock and awe but when you break them down to their parts: 1 day of their license fee, 1 hour to drive to my residence, 1 day of vehicle cost/insurance, 1 hour driving to a supply house, 1 day of a equipment lease, they might amount to a couple thousand at most to the job itself. There's also a lot of efficiency they can find in them. For example, they stop at the supply shop on the way to the job site and bring the equipment with them on a trailer (3 birds one stone kind of thing). A lot of these things are also just included in the 2 day timeframe I've observed as being sufficient. There's going to be a part of the day where they are sitting in their truck while the lines charge or something like that.
This doesn’t get shouted nearly enough. >90% of New England housing stock older than 30 years is not remotely worth the price they’re commanding. They’re either dumpster fires of knob-tube wiring and sagging floors, or contractor “spray foam specials” that make deliberate errors like the OP’s post points out. Yet because zoning laws are strongly tilted in favor of existing owners (and who are predominantly NIMBYs), it makes teardowns a costly affair on their own - and getting approval to build a new structure can take years, if at all.
Housing shouldn’t be disposable, but it should be readily replaceable with modern techniques and efficiency gains, provided it’s up to local code.
But to your point, we consider way too much to be "historic" and I'd like for that to change. You really should be able to tear down almost anything you'd like and rebuild as long as it's to code/zoning, and zoning needs to be cut back to things like dimensions and use, not appearance. Being old shouldn't make something eligible for historic preservation on its own.
everything else is none of your business. (Okay, I might have missed something but it is on those lines)
I tend to disagree with the need to tear stuff down just because it's old: it's so terribly wasteful. We need to get better at adapting, reusing, and adding on to older buildings. Granted, when developers just want to use the cheapest materials possible and build something that will start to have serious problems in 20 years, it's a problem, to say nothing of the loss of serious knowledge in various skilled trades.
[1] In most cases the National Register of Historic Places aspects of integrity are used for evaluation: integrity of location, design, setting, materials, workmanship, feeling, and association.
I've also DIY installed 3 mini split units in the house -- the last one being an AC / DC unit that directly gets powered via 4 panels on the roof during the sunny moments of the day.
Built a new addition 3-4 years back. It's far better insulated than the main structure, but the wood stove and heat pump combo keeps winter mostly at bay.
Anything over 30 years is insane.
It's greener because it's not burning fossil fuels (directly, anyway) vs. a propane / natural gas furnace, and it's more efficient than resistive heating.
Is this really the correct terminology? I'd say every AC is a heat pump, whether or not it can run in reverse, because that's how it works. It pumps heat from a colder place to a warmer place.
If it has been crippled so that it can't run in reverse, that's crappy and unfortunate, but it makes it no less of a heat pump.
The words "air conditioner" don't literally mean much at all. It doesn't refer to a humidifier or a hepa filter for instance, yet the term air conditioner has a distinct meaning that is silly to try to pretend not to recognize.
Same for heat pump.
> yet the term air conditioner has a distinct meaning that is silly to try to pretend not to recognize
Well, yes, in US it apparently means "heat pump based space cooler". Where I live it means "heat pump based space heater and cooler".
I agree with your logic both modes of operation (heat/cool) are both pumping heat.
Cripple is a fairly strong word here. HVAC is hyper optimized for cost/simplicity at the expense of comfort and efficiency. Which kills me. The industry is also stuck in the 80s in terms of power electronics. Variable speed control on the fans and compressors are a BIG deal. Like 20k for the gear. Even though the BOM cost is dirt cheap. Look at Carrier Infinity if you are curious
MANY Megawatts worth of power would be saved if they just included a directional valve, some speed control PCB and electronic expansion valve
Well... I'm in Europe, so I don't know if I ever saw a heat pump that can't operate both ways :-)
Yes, it pumps heat, but it's generally not referred to as a heat pump if it doesn't have a reversing valve and all the accoutrements that go with it (coil defrost heater, etc). I wouldn't say not having all those parts make it crippled, a refrigerator/freezer isn't crippled because it can't heat food, although some commercial units can be set to keep cold food cold or hot food hot because they have reversing valves.
If you have utility natural gas at reasonable prices, gas fired heat can be very economical, and it might not be forseable that you would ever use electricity for heating, in which case a reversing valve is a waste of capital.
Heat pumps run an AC in reverse which can give a COP of 3-4. (300 to 400 percent efficiency)
or if actually burning fuel for heat. Could just remove the need for direct fuel burning altogether. Highly dependent on area, and associated costs. I recommend that you run the numbers for your area
Have few friends who got certificates in order to charge their
I installed the lines, did all the vacuum related work. Then just cracked the valve on the unit to distribute the refrigerant.
I had a bottle of refrigerant on standby from a buddy. Didn’t need to use it . I was going to get the EPA cert, if my buddy didn’t exist. I heard it’s super straightforward
Sorry but it's deprecated
Ignoring those requirements is often the most practical way with very limited negative consequences.
It also allows using much cheaper units - from what I've heard in Germany the unit (without the install cost!) will cost 2x as much when installed through an official installer compared to a high quality free-market option, but of course the installer will only install units sold through them so many people may be priced out of the legal route completely.
mrcool also has ducted units that comes with precharged/vacuumed lines. very tempting as one of my hvacs lives on extended timeline and quote for a new one was $25k 2 years ago
https://www.epa.gov/section608/section-608-technician-certif...
It was a little scary, I had not done something like that before but a little research and it all turned out fine and has been working well.
The inside unit happened to fit pretty well with a little adjustment in the place the old one (from the 1980s) had been, and I made my own connections to the ductwork. I placed the 2 ton outside unit on the pad where the old one had been. I did have an AC company come and remove the Freon from the old unit, then I cut it up and took it to the scrap yard.
I was able to do this with no vacuuming lines as they sell precharged kits with lines similar to mini splits. It's been over a year and it worked like a charm through summer and winter. It took about 5 days or a week including removing the old unit, pulling the lines under the house, setting the inside and outside units and buttoning everything up. The reason it even took a week was a I did it entirely myself including moving the units with roller logs.
I saved over $6,000 from what I was quoted from an HVAC company which I felt was entirely worth a week of manual labor.
I would have started figuring this out before spending any money on a mini-split. OP, your climate envelope has failed somewhere. Spend some more money on a IR camera and try and identify where that leak is. Your basically just air-conditioning some of your apartment and some of the outdoors.
a friend paid a similar company the same and the work looks like total garbage, they're didn't even properly set the pad to place the outdoor unit on - and the techs are absolutely clueless about how the systems work
First sentence of the Prologue.
And $1,000 for the Wi-Fi module? I was looking at the part when comparing the cheaper and more expensive units (which either don't or do come with it from the factory), it's $60 to buy separately.
That is so crazy expensive to install and $1000 / month electricity bill what!?
My electricity cost to run this unit every night is ~$55 extra
Right!?
I live in India. The summers can be 40C. So $500 for an extremely energy efficient split-ac from a local manufacturer that does up to 12K BTU/h and $50 for installation.
I ran it 16h every day at 40% capacity for 2-3 months with the rotary inverter compressor pulling about 250-300W when cooling for a total power consumption of about 180 kWh per month.
No idea how they justify the time and cost over there.
Then again they pay tens of thousands of dollars to install solar when it's 1/10th of the price here.
Ah. That answers my question about how you ventilate the apartment for fresh air: it's thoroughly perforated.
> one from the clothes dryer (when I hold an incense stick up to it I can see it pulling in air even when it’s not running)
A normal vented clothes dryer can vent something like 8000 cu ft of air in a normal drying cycle (i.e. all of the air in their apartment). If that's running all the time somehow, that could definitely explain a lot. If that's the case they should fix it, and maybe explore ventless heatpump dryers.
E.g. the 20+ year old common German dryer that runs the clothes air closed-loop, first through the clothes, then to a heat exchanger with drainage geometry (typically feeding into a tray you have to pull out and pour out after each cycle), then across an electric heater, circulation fan, and back to the clothes. A second fan blows room air across the heat exchanger; the dryer action relies on the clothes being much warmer than room temperature such that the desired relative humidity of/at the clothes doesn't survive the cold from the room temperature.
Poor insulation does not explain it, a heat pump should still be heating that poorly insulated space at much higher efficiency that space heaters.
The physics makes sense but I wonder how strictly these units are tested. The control loops for things like deicing the outdoor coils are complex.
This esphome project has great integration with home-assistant and Apple Home and I’d highly recommend this approach over the Mitsubishi app if your unit is supported and you’re willing to do a little work.
We already installed a Daikin Altherma 3 air-to-water heat pump three years ago, which heats around a thousand meters of underfloor pipework + domestic hot water cylinder, but recently added a Daikin air-to-air heat pump. This is relatively new to the UK, at least in homes, so there aren't many contractors in the market yet.
Making good afterwards is certainly the challenge - I'm still repairing the plasterboard (drywall) holes, which I needed to make for access into the eaves. (I preferred this to having lots of external plastic trunking.)
I'm looking forward to seeing how the air-to-air heat pump helps with our winter humidity.
Packaged Terminal Air Conditioners (PTAC) are self-contained heating and cooling systems designed to be installed through a wall, commonly used in hotels and apartments.
You’ve probably seen them at a hotel.
About $10,000 per unit (including the PTAC removal/wall repair), sheesh. A new mini split in my St Louis (city) house was $5.5k, and that was one rung up from lowball $4k contractor.
Also, instead of the OEM wifi module, i had success with a sensibo, which has temp/hum/CO2/TVOC sensor, HomeKit control, and an IR blaster. I took that route when I learned the wifi module was locked down to their app, with no HomeKit.

My phone dies and the technician says I have to call a locksmith and pay for it myself. Now I’m in small claims court for $1275 no good reason other than my property management company enabling extortion by a locksmith. All they had to do was hire or train someone into being competent lock driller.
Real estate industry in this city is a toxic grift game. People are very nice here, but these real estate people are the “assholes” in which everyone refers. The whole thing is rotten except for maybe 5% of landlords.
