Particularly ironic that this is being framed as "unreasonable" because landlords themselves directly argue that their upkeep of the house justifies the significant upcharge they take from tenants. Like, even if we argued that landlord as a career is 100% acceptable and valid, that would literally be your job, would be like a professional chef complaining about people saying "make me food!"
I'm sure that is a legit issue and the menu should be planned to reduce that load. In this case the guy was more suited to repetitive jobs in larger scale kitchens which mine isn't.
I had a rentoid that would call me for the most insane shit all the time. Changing light bulbs, fixing their own personal AC unit and stopping a neibourhood dog from barking.
When they were evicted I held the damage deposit because the hardwood floors and internal doors were damaged to fuck by their dog which they tried to claim as being normal wear and tear.
Bad renters exist, but for every story like yours I have five places I've lived in where it took months to fix the A/C in summertime and the landlord just let it fucking go meanwhile holding out their greedy mitts demanding $2000 a month.
2 grand! To live in 90° heat, if I wanted to do that I'd just live on the street.
This will vary greatly from area to area but in most places for a tenant to withhold payment legally the property generally has to have a problem that would make the property "unliveable". Like the front door falling off the hinges, no water or no functioning toilets or the landlord has to ignore the problem for an unreasonable length of time.
The A.C breaking in the beginning of summer and it taking a week to get an A.C company to look at it probably doesnt count. Them leaving the A.C broken for the whole three months probably does.
