Try to get the temps corrected ASAP when money permits. Snakes can be sick for a very long time before they start to show signs outwardly that we can visually pick up on. Regurgitation is easy to spot but respiratory infections will not show symptoms until its well established in your snake. That will require vet visit + antibiotics; which is something you will want to avoid.
Hopefully you can correct the temp issue soon before you start to run into any problems.
