Hi. I have a quote from a reputable HVAC company for complete system (A/C and gas furnace). System is a basic one. It's a Rheem and it includes a 2.5 ton condenser and a 3 ton evap coil. I looked it up at the ARHI web site and it is listed there:​
RHEEM RA1430AJ1 RCF3617STA R801CA075417M 28600 12.50 15.00 900​
But I've read online in multiple places that the condenser and evap coil should be the same tonnage.​
I have another quote for a Bryant that is 2.5 ton for both, but that quote is $300 more. So, I am leaning towards the Rheem due to the price, but am concerned about the size mismatch. Should I be concerned about the size mismatch?​

Coil tonnage ratings are in name only.

The required coil varies depending on efficiency and design of the unit.

Higher seer units can require a 0.5 up to 1.5 ton larger indoor coil to get rated capacity and efficiency. This is common when the coil nominal tonnage is for a 13 seer.

As long as the coil is an approved match and suitable for your installation, you're good.

Thanks. This would be a basic 14 SEER system.
The 14 needs a bigger evap coil than the 13.

The real seer rating is determined by a combo of the outdoor unit, coil and furnace.

What you've posted shows the match-up is 15 seer.

Some marketed as 14 seer outdoor units hit 16 with some matchups.

It will be fine.
