My wife thinks that she can fix anything that is wrong in the house. She often gives me a hard time when I want to call a professional instead of waiting for her to service the problem, and I went without a garbage disposal for 2 weeks, because she wanted to fix the machine. She got the problem worked out, even though it was totally messed up for 2 weeks without our garbage disposal in the kitchen, and my wife was away at a business meeting when a problem with the air conditioner came up. I was afraid that she would ask me to wait if I told her about the problem. I decided it was better to call a repair professional first. I contacted the repair professional about the A/C and I made an appointment. The next time I talked to my wife on the phone, I told her that I made an appointment with the A/C repair service because the equipment was making a weird noise. The equipment wasn’t making a weird noise, even though I knew that would make my wife feel more like it was more of an emergency than if the temperatures were simply warmer in the house. The repair contractor found the problem and fixed the issue in less than 2 hours. It turned out to be a problem with low freon. That is not an issue that my wife would have been able to service anyways, then you have to have a special license to add refrigerant to the system, we would have needed to contact a service contractor and Heating and A/C professional.
