Reasonable AC repair time
I have a lease on office space which states.
Tenant agrees that it will, at all times during the term of this Lease, and at its own cost and expense maintain a maintenance contract for the heating and air conditioning system., and provide Landlord with a copy of same. Should the heating and air conditioning system fail during the term of the lease Landlord agrees to pay replacement costs of the heating and air conditioning system.
I have the maintenance contract and the last service the AC company did was in November of 2006. They stated: Replace complete system. System leaking freon. Evaporator coil rust out. Unit not efficient.
I gave this info to the landlords representative and they did nothing. Today the AC system is making a loud noise and blowing hot air.
My question is are they obligated to replace the system based on my AC company’s recomendation? And how long do I have to give them to repair or replace the system? If they do nothing is it a breach of the lease agreement?
Thank you

Florida rental property sold – transfer of leases to new owners
I own rental property in Florida and it is being sold. Tenant is concerned new owner may not honor their lease.
Is new owner obligated by law to honor lease agreement with tenant that was signed by me after sale is completed? If yes, can you site the Florida statute that says this so I can show tenant?

Rent Increase – Retroactive?

Rent Increase – Retroactive?
This is a complicated situation – 1) I currently rent a house owned and operated by my employer; however, it is not part of my employment agreement. 2) The written lease agreement is on a month-to-month basis, and entered into as an incident to my employment. 3) The rent for the term of the lease is $412.50/month and is paid through payroll deduction. 4) I was notified on 10/15/02 that a ”scheduled rent increase” became effective 10/1/02, and that this was ”the final scheduled increase over a three year period.” 5) I was never notified of this scheduled increase, nor the previous two increases. 6) This ”schedule” was never a provision of the original agreement.

What, if anything, can I do?
