I am new here and need some advice. HVAC is not my field of expertise so I am looking for things I am probably missing in my decision making process.
My current home gas furnace and AC are 20 years old. Once a year some small part quits working and I have a professional come in and diagnose/repair the parts. My technicians keep telling me the life-span is over for both my furnace and AC units.
This past week the furnace gas valve has been acting up. Sometimes it will just turn the gas off right in the middle of the heating cycle. I did not figure out the problem was the gas valve, I left that up to the technician.
Here are my options:
1) Replace the gas valve for a bunch of $.
2) Just wing-it and hope I make it through the rest of this winter.
3) Replace the AC and Furnace for a bunch of $$$
I don't have the a bunch of $$$ so I would be charging the new system on credit. I am a little worried that if I pay the $ on a gas valve then something else will break and the cost will just keep going up.
I just wonder if I am missing other options I could be thinking about. What would you do?
