How not to get your HVAC stolen while your house is being rehabbed.

[Jamie Wooley]

I have my first house under contract and it needs a new HVAC.  I do not want my contractors to work in bad conditions but I also don't want the unit to get stolen.  It is cold outside and I can't expect them to work with no heat.  What to do?

The house I bought is in a low end neighborhood in Dallas and I am clueless here.  Any thoughts???
