First American. Home Buyers Corp First American Home Warranty Will not repair/replace a/c that is documented to need repairs and costs a fortune to use and is endangering my health national Nationwide

I have been reporting documented problems with my a/c unit for over a year. In the summer I have to keep my a/c set at 83° to keep my bills lower than $400/month. I also have a heart problem aggravated by the heat. First American Home Buyers Corp has had the warranty on my 912 Sq foot condo since I bought in 2012. 

Despite documentation that my a/c is beyond just cleaning the coils, 1st American will not address this obvious problem. My condo uses enough energy to run a 5,000 Sq foot home with a pool but until my a/c dies this company will do nothing.

They are very quick to take my money but when I called last year regarding the same problem they sent a tech out who turned the a/c and heat on and refused to look at the interior of the unit, the parts documented to need replacement, and he refused saying as long as it blows hot and cold it works and then demanded the $65 fee which I refused as I told them it "worked" when I made a claim just not efficiently. 

My next winter bill is projected to be over $100 when my mom, who lives in the same complex with a unit 100 Sq ft bigger, pays about that much in summer keeping her house at 72°. No sane person would claim that my unit is in good working order. Because one of the issues is badly dirty (25 year old) coils, the supervisor I spoke with today said i would have to pay ($450) to get those cleaned before proving that that is not the only problem preventing my a/c from functioning.

I am not investing any amount of money to repair a 25 year old system except to replace it and as soon as I have dealt with it i am cancelling my contract with First American who are a bunch of crooks who do not honor a warranty.

If your car is supposed to get 35 msg and only gets 5 you would be at the mechanic because while it drives it is clearly not working. The same applies here.

I spoke with Rashida Jacques on 12/21 and she said that if I have a heart problem and have to keep my house at 83° to stay under $400/month then something is not right and they need to honor their part of the agreement for which I am paying. She asked me to send documentation of the problems with the unit and would call me back. Well not only did she not call but the supervisor today said she has no authority to make outbound customer calls although she is in the conflict resolution department. I guess she got in trouble for speaking the truth.

Ultimately,  this company has no interest in repairs. Just profits. Even if it's literally killing me!
