Default Another AC Question

Have to replace a 20 year old unit, which is in an occupied rental unit, so I can't spend a lot of time looking for bargains. Central NC.
Got a quote for a two ton Carrier, 13 SEER R410, inside air handler, outside compressor unit, line set, installed for $4700, and no charge for the 3 service calls this week on the old unit. Do I need to look any further?

Sounds about average. You might be able to get some quotes closer to $4k. The biggest factor is having someone who knows what they are doing install it, and be available for service down the road. Also there is no reason they should have to replace line set UNLESS they found a leak in the line set. Ask about warranty too, pretty sure most newer units are coming with 10 year warranties on parts.

Does OTD mean that is your equipment price, or complete installation? New install, or replace and dispose of old equipment? I might find a cheaper price, but then he might want to get paid for his 3 service calls this week-end and today, so that's sort of a wash. It's going to be low 90's here, and I have tenants without AC since Friday, and that's my main concern. This company also services my commercial sites, and when they go down, I want fast response, so I am not trying to be a hard ass and rock that boat. If it's a fair and normal sounding quote, I will roll with it.

llessur2--I wasn't sure about the line set when I said it, everything had been over the phone at that point. I will have a written quote in the morning, and yes there is a warranty.

It's best to replace the lineset if possible when going from r22 to r410. If it's an attic install with lines thru a finished house (and the lineset is not leaking) then the lines are flushed out. 22 and 410 use different oil and they are not compatable.

$4700 is not outragious, especially with 3 calls gratis.

As the seer rating goes up the requirements for flow for the line set change, you need a bigger line set to accomodate.....I am looking at upgrading my system as well going down the same road......

The outside unit sits at the corner of the building, and the air handler is in the crawlspace of the second condo, so it's all on the same level.

Higher Seer should not change the size of the line-set. As long as line set is flushed and then a vaccuum pulled you'll be fine. Pretty sure only time the lineset size should change if it is an old unit and is running 1/4 liquid line (too small for newer units). i was told these were mostly old Rheem and Rudd units. Either way in your scenario sounds like I would simply go with them if they also service your commercial units. Try and see if they will give you a better deal. If you are a good customer they should be able to work that price a little for you.
