In the area where I live, central air conditioning isn’t enough. There’s simply too much humidity in the air. The damp conditions make the air feel warmer and horribly sticky. It causes issues with mold, mildew and bacterial growth. The damp and hot conditions are the perfect habitat for dust mites, cockroaches and centipedes. The moisture can cause wood to swell and warp. There’s all sorts of concerns with air quality and the resulting health problems, such as aggravated symptoms of allergies and asthma and respiratory infection. Even modern air conditioners aren’t designed to combat such high humidity. Lowering the thermostat setting simply puts greater strain on components. The system runs for longer cycles, experiences wear and tear and leads to higher energy bills. Over-cooling the house doesn’t solve the problem of too much humidity. I tried portable dehumidifiers and wasn’t happy. The portable units weren’t effective and yet required constant maintenance. I then consulted with a local HVAC contractor and asked for recommendations. He installed a whole-home dehumidifier that installed right into the air handler. It pulls humidity out of the air as it passes through the cooling system. I was downright amazed by the improvement. I’ve been able to raise the thermostat setting significantly and yet the house feels cooler and is way more comfortable. My whole family sleeps better at night. We don’t suffer as many headaches or congestion and feel more productive during the day. The savings on my energy bills will quickly recover the investment into the dehumidifier. I like that the air quality accessory runs almost silently and only requires annual maintenance.
