Please remember as we begin our summer season that the %RH on the thermostat does not directly tell you the amount of Humidity in the home.

Relative Humidity % is the amount of Moisture in the air compared to how much Moisture the air can hold at any given temperature.

So if moisture is water (in gallons), and temperature is a bucket (in gallons) we can see the relationship.

If you have a 75 gallon bucket (75 degrees in the home) and you have 37.5 gallons of water in it, you would have 50% Moisture Relative to how much the bucket can hold.

If you lower the temperature in the home to 68 degrees (making the bucket smaller) and maintain the same amount of moisture (37.5 Gallons), the amount of moisture in the bucket relative to how much it can hold just went up to 65%.

You cannot change moisture content by increasing or decreasing temperature… it can only be changed by adding or removing moisture. This is why in most homes in the Deep South; the answer to high levels of humidity is a Whole Home Dehumidifier like the UltraAire 70H.

Contact your local Coburn's location for more information on a whole home dehumidifier.

Winter Carbon Monoxide reminder,

As homes are being built tighter down in the Deep South the threat of trapping (CO) Carbon Monoxide in these homes has become increasingly real.

Our mindset has to change from the floor heaters we had all around grandma’s home venting into the rooms. Because new homes are tighter, the heater, water heater, stove, oven, fireplace, etc. are even more important to have checked out for a combustion analysis. Gone are the days of saying “It’s got a blue flame, it must be OK”

Our friends north of Interstate 40 have known about these issues for years and we are just beginning to see the effects of tighter, negative pressure, homes back drafting CO into the lives of our customers.

The states code require UL rated CO detectors in new construction homes but they will not alarm until they reach 70 parts per million (ppm). Even if you have a digital one UL restricts it from showing anything below 30 ppm. The problem with that is firefighters generally are required to don breathing apparatus at 25 ppm.

If you have a situation with a tightly constructed home with any fuel burning appliance in it, please consider the use of a Low Level CO detector such as the Defender LL6070 to help protect your customers from low level CO poisoning.
