Anytime my Heating, Ventilation, and A/C has an issue, I just cringe inside. The reason is that my hubby thinks she is a Heating, Ventilation, and A/C professional; She never went to school, studied or logged in field hours. She just thinks she is handy enough to do a heating and cooling repair. My hubby tries, but she is not good about Heating, Ventilation, and A/C. The first thing she does is usually take the Heating, Ventilation, and A/C completely apart; I hate it when she does this! Occasionally the Heating, Ventilation, and A/C just needs a new air filter. If the air filter is dirty, the Heating, Ventilation, and A/C won’t turn on. It does not want to mangle itself heating and cooling with dust inside, you just need to upgrade the air filter, not take it apart. Occasionally the A/C just needs refrigerant or the heating system needs lubrication. Taking apart the idea is not constantly required, but my hubby does it. She then messes around with the inside of the system. She is way too rough and constantly seems to be in a rush. It is a miracle she has not broken anything pressing yet, however what I do is wait for him to go to work or go to hockey. The moment my hubby is out of the house, I deduce the repair and repair it. There are times I need to call a Heating, Ventilation, and A/C dealer. I have to be real sneaky with this though. I need the Heating, Ventilation, and A/C woman to come in quick and leave no evidence of her presence in my home. It would hurt my hubby’s feelings if she thought I doubted her skills.
