haukex++'s solution is good, and asks an important question, since your specs were not internally consistent regarding exactly 55. However, in case you were curious about your logic specifically:

Your version doesn't compile for me as-is: you have an unmatched curly bracket. Clean up the formatting to only do one thing per line, and you should see it:

if ($tempdesc >= 55)
{
    if ($tempdesc2 =~ /electric/)
    {
        print FH_OUTFILE "\n";
    }
    else
    {
        print FH_OUTFILE "free_batteries\n";
    }
}
else
{
    print FH_OUTFILE "\n";
}
}

After removing that final } (shown in the SSCCE below): it seems to me to do what you want (assuming that "greater than 55" means "greater than or equal to 55", to match your >=).

use warnings;

use strict;                                                           
+                      # ALWAYS!!!

open FH_OUTFILE, '>&', \*STDOUT or die "err dup STDOUT = $!";

    {price => 55, title => 'i am expensive electric, and want a blank'

    {price => 55, title => 'i am expensive gasoline, and want to print

    my $tempdesc = $hashref->{price};
