The guys showed up when they said they would with lots of great looking equipment to do the job. The guys respected my house and they did the job they said they would do. After it was completed they showed me the numbers from the air testing and I was a little unsure what this would mean for me. But after almost a year now I find the house is much more comfortable and I am using less energy to heat it now.
I would recommend this procedure for older homes for sure. Never a regret!
