My property owner told myself and others not to call him with Heating, Ventilation, plus A/C issues when I first moved in. He said that he had a Heating, Ventilation, plus A/C corporation scrub plus care for everything. The property owner obviously lied plus did not want to deal with paying for a Heating, Ventilation, plus A/C repair. I guess he lied because the washable air filter in the system was disgusting when I moved in. There was tons of dust plus dog hair in it. The whole inside of the Heating, Ventilation, plus A/C had large gobs of dirt in it too. After cleaning it, the Heating, Ventilation, plus A/C worked better, however not great. The Heating, Ventilation, plus A/C device works by either doing heating or cooling. There is a toggle on the control device that is pushed to either heating or cooling. If I have the A/C on accidentally plus it is winter, I will get cooling. If the toggle is on heating plus it is a warm Summer day, I get heating. I always have to option what I want, heating or cooling. There is no set a temperature plus let the Heating, Ventilation, plus A/C figure out what to do. I do not care for deciding when to move to heating or cooling. I don’t know the system is very enjoyable at the air conditioner function either. I barely notice when the cooling is on, then for very warm days, the control device can be set super low, plus the A/C just can’t keep up. I use the ceiling fans with the A/C plus the new home is still hot. I know the property owner knows something is wrong with the cooling function plus did not want myself and others to call him about it.
