The message I have for you today is a bit counter-intuitive. A properly designed house could have intentionally been DESIGNED to not be comfortable on extreme weather days.
Here is why I am willing to be uncomfortable 10 days out of the year. It’s all about efficiency. Most of our cooling systems are drastically over-sized. What that means is the equipment kicks on and quickly returns our homes to our desired 70 degrees. Homes with over-sized equipment are often cold and clammy.
Cooling equipment is designed to cool and also remove humidity from the air. Moist air needs to be colder than dry air to feel comfortable. If you have visited the both Southwest and the Southeast regions of the United States you know the difference between dry and humid air. To remove humidity we want our air conditioning system to have longer running cycles.
When it’s time to upgrade your HVAC equipment do not get talked into larger equipment. It is more expensive up front, and the short cycling can cause it to break more frequently than properly sized equipment. Demand that guys like me make a scientific case for the things we specify into your home.
The path to both resource efficiency and comfort is to 1st change the energy load required to keep your home comfortable and then use the highest performing equipment you can afford [that is properly sized to your home]. I can help you walk down this path as far as you’d like to travel.
