Everything looks broken!

I recently bought a brand new home for the first time in our life plus I thought it was going to be the best thing to ever happen to my life. Turns out it has been nothing except for 1 headache after another for the past year and a half of our life. It started off with the roof getting a leak in it. It was Springtime at the time plus pouring rain very heavily, so of course it became an immediate issue that had to be fixed up. Then the Heating, Ventilation, plus A/C system started chopping down piece by piece. First off, the oil furnace in the basement quickly turned off during the evening which I didn’t find out about until the middle of the afternoon when it was chilly in our bedroom. The concern turned out to be a bad motor in the fan that had to be replaced. I cursed the Heating, Ventilation, plus A/C supplier I hired for the price they quoted until I looked around plus found they really were certainly the cheapest. Next, the undefined broke the hour time I used it only about 6 weeks later. Again I had to call out the Heating, Ventilation, plus A/C supplier to resolve the problem, plus again I felt they charged myself and others too much to fix it until I compared the price list with other local Heating, Ventilation, plus A/C companies, and last month the heat barely felt love it was moving through the vents even though the oil furnace appeared to be running normally. This time there were little holes in the ducts that the Heating, Ventilation, plus A/C professional had to patch. In a couple of spots he certainly had to put new pieces of duct in because the injure was so bad. He said he had no clear plan how it could get so bad so quickly, so I suppose I am cursed.
