All,<br>  <br>  Like many older homes in HP, my home lacks proper insulations.&nbsp; I  am looking for someone who has experience with insulating older homs  via blown-in insulations or other methods.&nbsp; Has anyone done this  and was it worth it in terms or bringing down the heating and cooling  bills?<br>  <br>  Thank you. <br>  <br>  <BR><BR>Sincerely, <BR>Sam Al-Droubi, M.S.<BR>saldroubi@yahoo.com
