The only worse than your air conditioner not working during the summer heat is your air conditioner intermittently working. My unit would stop cooling at different times but then start working again. When the technician arrived, the unit was working properly so my biggest fear was him not being able to determine the problem unless it was witnessed. I did not want to start the process of guessing on which parts to change and calling them back out when it didn’t fix the issue. Fortunately, he was a very competent technician and was able to determine the problem and fix the issue before he left. Now my air conditioner is working great again.
