Upgrade a 15yr system?
New member, first post.
Location: Metro Detroit area, Michigan
House: 40yr 955 sqt brick ranch with basement,3 bd, east-west facing
Furnance: Lennox-G23Q 2/3 -75-4 80% AFUE installed 1997
A/C unit: Lennox HS29-024-2P 11 SEER installed 1997?
Last year I had the ignition control module replaced, this year the control board replaced.
We are planning on staying in the house at least another 15yrs, the questions I have are:
1. Given the age of both units and the repairs I had done to the furnace, is it time to starting looking to replace both units?
2. Are the size of the units correct for the size house.
3. Given how long we plan on staying in the house, should I look at Furnaces that are between 85%-92% AFUE, 13-17? SEER for A/C unit. For the best return on investment?
4. Are certain brands better then other? if so, what makes them a better long-term investment? (understand brand preference can come down to personal choice)
I welcome your thoughts and comments.
