If this is a central air unit,, it  might be better to shut off vents in  the top floor rooms and shut doors to rooms your not using, put single A/C unit in rooms you need to cool on 3rd and use only if you need to.did the service tech suggest a recharge for the A/C unit.. maybe it just needs more coolant, .. ..hard to know but I'd ask the landlord to take a look and see if it can be serviced.

Excellent reminder for all, thank you.I have a contract with a fire protection company to test and maintain detectors, as well as maintain/recharge/replace fire extinguishers.  

I used to put a small one in each of my units but now I maintain and recharge 2 large extinguishers in common hallways.

On the weekends, I let my body recharge and sleep until it wakes itself up. 

Battery should last around a week before needing recharging. 

Occupancy numbers can be an issue if you have low recharge rates.Also consider if electric is out you have no water. 

Good managers deserve to take a break from the park and recharge their batteries.  

Think of it like a ranch/retreat where Pastors and their families can get away for a few days to recharge and focus on themselves and their spiritual and mental health.The Hope would be to split all investment profits 50/50 between the two.

I just recharged a unit with Freon R-22 for a 1989 Trane System.

2- Do any of you buy the rechargeable extinguishers or the one-time use?
