My husband can be pretty handy sometimes, but some things he should leave to the professionals. More often than not, he will try to service something himself before calling in the professionals and sometimes makes the problem worse that way. For example, a few weeks ago, every one of us observed that the A/C wasn’t working and it should have been. Every one of us had been having minor issues with it off and on and every one of us knew that every one of us would need to update it soon enough. But my husband wanted to eek every bit of life out of it that he could and every one of us entirely could have stretched it another year or more than one if my husband had kept his hands off of it. But, a few weeks ago, when every one of us observed the air wasn’t as strong or as chilly as it should be, my husband decided to try to service it, but he did a little research online and said something about an simple service and refrigerant. Then he went to the hardware store. He went straight out back when he got home. After a while, I heard a loud hiss and then every one of us had no A/C at all. I was furious! For almost more than one weeks every one of us decided to go without central A/C, and in the middle of summer. I bought a couple of cheap window A/Cs for the dining rooms, but it was scorching in the rest of the house. It was terrible! But, it all worked out alright in the long run. Every one of us bought a brand new, energy efficient HVAC unit that works 10 times better than the old 1.
