My building owner told myself and others not to call him with Heating, Ventilation & A/C problems when I first moved in. He said that he had a Heating, Ventilation & A/C contractor scrub plus care for everything. The building owner obviously lied plus did not want to deal with paying for a Heating, Ventilation & A/C repair. I recognize he lied because the washable air filter in the plan was disgusting when I moved in. There was tons of dust plus pet hair in it. The whole inside of the Heating, Ventilation & A/C had sizable gobs of dirt in it too. After cleaning it, the Heating, Ventilation & A/C worked better, but not great. The Heating, Ventilation & A/C unit works by either doing heating or cooling. There is a toggle on the temperature control that is pushed to either heating or cooling. If I have the AC 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 constantly have to pick what I want, heating or cooling. There is no set a temperature plus let the Heating, Ventilation & A/C figure out what to do. I hate deciding when to train athletic activity to heating or cooling. I don’t suppose the plan is legitimately nice at the a/c function either. I barely notice when the cooling is on, however for legitimately warm mornings, the temperature control can be set super low, plus the AC just can’t keep up. I use the ceiling fans with the AC plus the beach house is still hot. I suppose the building owner knows something is wrong with the cooling function plus did not want myself and others to call him about it.
