Replace one unit or both ??
1.5 ton unit (trane) 10 SEER and 4 ton Trane 10 SEER unit, both 11 years old.
1.5 ton unit acting up (freon leak, maybe more issues).
4 ton unit works fine.
Do you recommend replacing the 1.5 ton unit with 15 SEER and keep the old 4 ton unit or do you replace both - especially if you have a good deal to replace both units at the same time?
Thoughts? Location is Florida. Units are sized right.
Well, if you can afford both and you are getting a good price on both of them, why not? We're not paying the bill.
What is the replacement equipment?
1.5 ton goodman 15 SEER
4.0 ton Amana 2 speed 15.5 SEER
How do you know they are bothsized correctly?
In Florida ,I hope you aren't dealing with someone who telemarketed you.
- Seem correctly sized, both struggle a bit on the hottest of days and run for extended periods. The 4 ton MIGHT be oversized but not positive. However, if it is the two speed system should take care of that issue.
- 1.5 ton serves 600 SF with computer/TV/stereo and several glass windows.
- 4 ton unit serves about 2700 SF with a good bit of glass.
- Goodman makes both. Amana doesn't make 1.5 ton two speed.
4 ton, replaced blower 2 years ago.
- 2 contractors same prices for 1.5 ton 15 SEER Goodman or 13 SEER Payne. The goodman contractor offerred to replace the 4 ton with an Amana for just a few hundred dollars more than the 1.5 ton. The Amana costs more than the good man (by about the price difference).
Also had 2 x electric bills this summer in the +400 range.
The 1" filter rack in the air handlers of Goodman/Amana units absolutely suck. I have to physically rip out the old filter during a filter change. Get a separate media filter cabinet so you do not experience the same aggravation I do.
Can you explain a bit more? I gather you have a hard time getting to the filter?
Although I don't agree on the equipment choice or the lack of a heat load calc, I do agree on replacing both units at the same time if for only for the fact that you will be saving money in both installation costs and efficiency. 1" filters are very inefficient, pretty much every filter company out there makes a 4-5" media filter AND cabinet now.
Changing both is probably your best answer for peace of mind and efficiency. You will reduce your electric bill and reduce your worries for 10 years...also make sure the contractor is registering you for 10 year all parts warr, or do it yourself on the goodman website!!! Look into the extended labor warr. Its cheap enough, should be a no brainer!!!
I don't understand why do you have to replace any, why not fix simple leak and be happy.
You will never get your money back anyway

2 x 11 yr old units 10SEER when new.
$400 electric bill. ($0.125/KW and going up)
With low freon the compressor ran a lot extra. Therefore the 11 year old compressor probably has an extra year of wear and tear. Plus, this is Florida, near the banana river (i.e. salty environment).
Do I HAVE to replace? No. Would it be smart? That is the question.
