Troubleshoot properly to avoid wasted time and energy.
I spent the summer in my basement. It wasn’t the coolest spot -- actually the rest of my house was colder. That was the problem. I was troubleshooting my air-conditioning system. Where I live, in Colorado, heating and air-conditioning equipment is in the basement. Troubleshooting took all summer because I did it wrong.
I was doing it wrong just like anyone might. I didn’t follow a troubleshooting process. I skipped all around. I made assumptions. I replaced parts. I took advice.
