She gets so angry at me and yells for days that there is something wrong with the unit. We have tried every way to explain why it is so high but she will not hear it. Any ideas about a better way to handle this? I am an only child so I have to deal with all the caregiving and I have read & studied this diease enough to know how fast things can change but until we get to summer I don't see this situation changing. Any suggestions?
Several suggestions made sound the best to me:
1. get onto a budget plan where they average out the costs and the bill doesn't vary much.
2. have the bill sent to you (this assumes that you have some control over her finances - if not, this really doesn't help.
3. if she has dementia, "fixing" this issue will likely result in getting angry over something else. No point in wasting a lot of time and patience explaining, reasoning or arguing about whatever it is she rants about - try to agree and change the subject. If she continues outbursts, perhaps her doctor can Rx something to calm her (very low dose of something that takes the edge off.)
I didn't see an age listed, but can say that yes, many older people seem to have a problem with being cold. Most of the ladies at mom's MC place have sweaters on year round! During an early heat wave here (New England) last year, I showed up in a tank top and jeans for a visit. No A/C at home or in cars, so I was HOT! They kept asking me "aren't you cold?" No, I'm waiting for my temperature to return to normal before I will feel the A/C here! Took at least a half hour for that to happen.
So you need to find a way around the excessive bill that triggers the outburst. Budget plan is easiest and doesn't cost anything. If you replace the thermostat, you could try reducing it a bit, but probably best not to reduce it much because then she'll just complain about being cold. Suggesting extra layers probably won't help either, if she has dementia. She won't remember to put anything on and continue to complain.
For those who have to share space with the cold-meisters, dress in layers yourself, so you can add or remove clothes as needed. If A/C is whole house, try a portable or window unit in your own room for sleeping in cooler temps. Our mother had a programmable thermostat, but would manage to shut off the A/C in summer (it had a toggle switch between A/C and heat)- I showed up once in the summer when she was still living on her own and the place was like a hot house. I was sweating within minutes. There was potential to do the opposite in winter, resulting in no heat! Brother replaced with a Nest, and she really couldn't mess with it - didn't understand how it worked. But, if she wanted it that hot, he would program it that way. He set it to control temp day/night and had a low temp warning for monitoring it.
(some suggested humidifier - if the heat and A/C is forced air, definitely consider this. the drier air tends to make it feel colder than it really is - the blowing doesn't help either. closing off areas not really used and reducing heat to those areas could help, but not if she is going to be opening them up just because. I have several rooms closed off to the cats, and closed the top vent covers - it is hot water system. hopefully this is reducing heat wasted in those rooms, but keeps them warm enough the pipes don't freeze!)
Keep a list of things the are out of character that your mother is doing and provide that list to her doctor. We did this for our mother and I made an appointment with her doctor and went with her, so the doctor would take it seriously and understand something was not right. I did mail the list ahead of time and her doctor was wonderful. Just don't give it to doctor in front of her, either mail ahead a time of an appointment or asked the nurse to give it to him and ask him to review it before coming in the room and not tell her about the list.
I wish you all the best. I know it is full time job just in getting everything set up, so she isn't upset, but in your control to make sure bills are getting paid correctly and she isn't being scammed.
My mother is currently in a memory care center and in the late stages of Alzheimer's and as for room temperature they keep it so warm that I am uncomfortable when I visit her. It is so warm that at times I have had trouble breathing, so I guess this is an older person issue. I'm not sure how the workers take that heat day after day. They do have electric heat throws, maybe that is something to consider for her, but if she has dementia/Alzheimer's reasoning with her will not work. They no longer have any reasoning skills.
