This question was created on the page: https://www.furnacecompare.com/furnaces/lennox/g61v.html.

This furnace was installed in spring of 2012. Noticed more as weather got colder. Heat bills have doubled since new furnace has been installed. Old furnace was 30 yrs. old. Furnace runs all the time and takes forever to heat house. Never seems to truly get warm enough. Is the set up wrong? Installer says set up is fine and doesn't wish to have anything further to do with us.

Hi,

Not enough information to provide much that can help you other than to say there is a range of issues that could be the problem, which includes the functioning of the furnace to the possibility that cold air is getting into the house from some sort of crack, open window (such as in the attic or basement), or some other reason. It could also be that the furnace was not properly installed or sized (too small and needing to run constantly to keep up?). It could maybe also be that the furnace requires some maintenance such as cleaning the burners (probably not likely since it was just installed) or filters (again, hard to say that this would be likely).

The first thing to do is go look at the LED error/fault code display for the furnace. You can find the display on or near the control panel and go here and look at page 60 for an explanation of what the different codes mean: http://www.greenwoodheating.com/products/manuals/gasfurnaces/G61MPV.pdf.

This will give you some indication as to if there is a problem with the furnace and what it may be. If there is no error code displayed (LED shows furnace to be operating fine) then there is some other issue that could be related to the furnace or one of the other issues noted above.

IN any event, you would do well to get a certified HVAC tech in to take a look as soon as possible. This person will be able to quickly identify the problem and fix it. Given that the furnace is so young whatever the problem is it may be covered under warranty and therefore free to inexpensive to fix. Do you still have the name and number of the person who installed it (it should be on a card attached or glued to the furnace)? That would be a good place to start unless you don't trust this person for some reason.

I hope this helps.

Best.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.

Sorry, just saw last bit of your question.

Definitely do not go back to the person who installed the furnace. If they were an HVAC professional and one who operates with integrity they should be willing to back up their work and make it right.

I would still say that the furnace should be covered under warranty so it may be free to little cost to fix. I still say you should check the error/fault code to see what information the furnace will give you and get in touch with a qualified HVAC tech in your area.

If there is no diagnostic code indicated you may be right that the install was no good. When you do get hold of a qualified HVAC tech he or she should be able to offer advice on how to proceed if the other person did not do a good job. They will also be able to quickly diagnose and fix a problem.

Good Luck!
