Stop wasting money

A furnace filter purpose is to help keep your furnace clean, not your home. Filter manufacturers do an excellent job marketing filters that clean your air, the only thing they do is restrict the air flow throughout your home and stress out your furnace and a/c. There are some excellent air filters on the market that are separate from your furnace, you can also install a UV lite in your furnace that kills mold spores. After all this spending on air quality remember that the clean air is outside, the answer is to exchange the air in your home. Check out the EPA's website. Just buy the cheap $1.00 filters and at a minimum change every three months but I recommend every month.

Facts About Water Pipes Freezing

This winter, I have been performing a lot of thermal imaging inspections to locate exactly where home owners water supply lines are freezing. Home owners are often surprised when their pipes freeze because the house doesn't seem cold. They are often puzzled about why the hot water pipes always freeze first. That tendency seems to defy logic, but there is a good reason for this phenomenon. Hot water pipes freeze faster than cold water pipes because hot water contains less gases and tends to supercool and freeze from the center outwards. Cold water, however, tends to crystallize and form an ice cover, allowing the water to continue flowing under the ice layer.
