Can you have a HELOC and Home Equity Loan?

[April C.]

Strange situation. We added onto our primary home about five years ago and rolled the construction loan and Initial mortgage into a single primary mortgage. We now have significant equity in the home with the one mortgage on it. We recently found that the bank is reporting the loan to Equifax as a Home Equity Loan. To our knowledge it was just a standard 30 year mortgage when we got it. 

We now want to draw on some of the equity to make other investment purchases but will we be able to do a HELOC or fixed home Equity Loan with the way our primary mortgage is reported? Is this something we can change without refinancing? We have great rates on it and don't want to completely refinance. What are our options? TIA!
