Do I need a new furnace?
My existing setup is:
Lennox G16 Conservator III Furnace
Lennox HS 18-44 Compressor
The setup is original to the house which was built in 1989. The only problem I have had with the system is that the A/C needed to be charged at one point. The contractor told me he would charge it for me, but he suspected there was a leak in the system and he would not guarantee that the charge lasted more than a month or two. That was 2 1/2 years ago. My house is always comfortable, there is no problem staying cool in the summer and warm in the winter.
I am thinking that it is getting to the age where I need to consider upgrading because at this point if anything does go wrong it is a waste of money to fix when I know it is going to have to be replaced sooner rather than later. Is my thinking correct or should I go with the old "if it ain't broke, don't fix it" attitude?
Could I get another 5 or 10 years out of the system? Even if I could is the savings I would get by upgrading going to help offset the cost over that time period anyway?
I am considering:
Lennox G43 Series
Lennox G61 Series
plus I have other contractors that will likely quote Carrier / American Standard / Goodman (but the price would have to be a whole lot lower for me to even consider not going with the Lennox).
My initial questions are:
1. Should I upgrade or wait?
2. Should I get the R410 compressor or is R-22 still ok? (the 410 is going to cost me a little more because my lines will need to be cleaned).
3. Is the variable speed G61 a huge jump over the G43? Can I justify the extra $$ over time? Should I?
4. My Lennox contractor said he did not have time to do a "full" load calc, but he had some chart that he claims is "always within about 5%" and that I should trust my contractor to properly size the units, is this a no no??
5. Is #4 enough to make me look at another contractor (that sells Carrier / Goodman / American Standard) that is willing to do a proper load calc?
Thanks for the info.
You have time, don't rush the decision, or the choice of system.
