Let’s put it this way—excess moisture can certainly hurt your Spokane Valley, WA HVAC system, therefore, a whole-house dehumidifier can, in fact, help it.
Consider the facts—humidity is the excess moisture that comes along with our higher summer temperatures that we’re all very familiar with. This excessive humidity makes us uncomfortable, and the only way to relieve this moisture is by lowering the temperature. So, this would likely lead you to turn your air conditioner to the lowest possible setting, right?
Well, unfortunately this makes your air conditioning system work harder, straining it and causing it to accumulate wear and tear faster than it otherwise would have. Plus, it doesn’t do anything to effectively remove the humidity in the air, so you’ll still be uncomfortable anyway.
