I'm just moved into a new house and I would like to plug up all the air leaks. The house was built in 97 so it's modern construction. I have read that you can use an infrared imaging sensor to see which walls are colder and possibly windows also. I've also read that using smoke sticks to see if the smoke gets blown around by the drafts can he helpful. Can one of these infrared sensors be purchased at a resonable price? I have not found one on the internet.
Should I just have someone come in and do a real test using a blower door and such? If so what kind of company does this? None of the HVAC contractors I've called really even know what I'm talking about. I get the idea that they would solve my air infiltration problem simply by installing a larger unit.
As a result of plugging up all my leaks I hope to cut down on the number of spiders and crickets that find there way into my basement. How do these bugs get in anyway? In my old house I thought I had everything plugged up but even the largest of crickets still found a way in. I want to do this one right.
Thanks in advance
