Replacing Gas Package- Advise appreciated
I am so glad I found this forum, I have learned alot from you guys. I have a 20 year old Carrier gas pack that I am looking to replace (48NHT024), last year it was very difficult to get the heat to come on the first time and a couple of months ago the gas company had a leak in their line and while they were repairing that, they notified my wife that our heat exchanger was basically rusted through and cautioned her about even trying to light it. So I am looking to replace it, as it is beyond its effective life expectancy. I have quotes to replace with a Carrier VLA24 for $4800 all the way up to a Trane for $10,200. Obviously the VLA24 is gas heat and electric air, just as I have now but more efficient. I am trying to decide if I should go with a more advanced/efficient package, I am thinking that a hybrid system with dehumidification is certainly worth considering. I am in middle TN and our electric rates are 8.231 per kwh and gas is ~.71ccf (.725/therm).
I am basically down to the VLA24 and:
Carrier 48VTA24 Performance series Hybrid @$6200
Am. Std. Gold series (haven't got the model# yet) @7200
Am. Std Gold Hybrid (no mdl# yet) $8900
I am waiting on a quote for the Carrier Infinity as well. Obviously all units are 2 ton units. I have not been able to justify the $$ difference between the Am Std and Carrier, so I am leaning toward the Carrier hybrid unit. I am 51 years old, know zip about HVAC and want this purchase to be the last one I have to make if at all possible. I would love to hear your thoughts and opinions on this, and what you think about the infinity series compared to performance series in the Carrier line.
