When homeowners ask “do humidifiers cause mold?”, they’ve noticed moisture on windows, a musty odor, or a patch of discoloration they swear wasn’t there last week.

At Pointer Cooling and Heating, we’ve replaced countless capacitors over the years, and believe me — they fail more often than you might think. What
