Can anybody tell what the seer rating is on my carrier air conditioner. The model number is 38CKC036510?

Question

It was installed right before I moved into my house not to long ago and im just curious as to how effiecient it is.

Answer 1

I have access to Carrier and that AC when used with an orfice type expansion coil, which I assume you have in your furnace, is 10.5 SEER. When used with a TXV expansion valve that SEER is 11.0.

I would not be too concerned about a unit that has a 11.0 SEER unless i ran the unit for many long months a year such as in Florida or the South of US where it is hot.

Your saving in the midwest with a 15 SEER on a yearly basis verses that 11 SEER which you have like in Chicago or Detroit or Dayton would only amount to about $50 a year in savings, if even that. Because not only would you be going to a 15SEER unit with expensive PURON coolant in it verses Freon 22, but you would be going to a high compression ratio and a high pressure system, wherein both the compressor and the lines are subject to lesser life due to the fact they are worked harder.

Answer 2

The SEER is the Seasonal Energy Efficiency Rating. The higher the rating up to 21,the less you pay for cooling. The indoor and outdoor coils must match. Look at a (ROI) Return of Investment,by energy cost savings, to be in the 3-5 Yr. range to be justified. With regular maintenance it should last well past 10 yrs,therefore paying you back the last 5-7 yrs, withe the same energy savings at the start,assuming the rates do not increase. Carrier or the installer will have your seer rating. Most units have a label or tag with the SEER on the outdoor/indoor unit.Most units installed since 2012/2013 have to be 13 SEER or better by EPA mandates. An Amp draw of your old unit and the new one will prove the energy savings.A bigger coil and multi speed fans I/D and O/D get rid of the unwanted heated faster with less energy draw (Amps) on the compressor and fan to do the same work as the old unit. If you can not get a ROI in 3-5 yrs.,it may not be economically feasible to switch. Keep the filters and I/D and O/D coils clean to maximize efficiency. Clean the ID fan motor and squirrel cage every 3-5 yrs..You can get I/D and O/D coils cleaners at HVAC supply stores or Home Depot or Lowes. Gallon jugs of chemical cleaner are better than canned sprays IMHO. A typical garden sprayer works fine to apply. Some cleaners eat gaskets so do not leave thm unused in the sprayer and rinser the sprayer with clean water after use and before storage. Twice a yr.(Mar./Sept.) is good to keep your coils clean and efficient. Rinse the O/D coils with lots of water. The indoor coil will rinse its self ,if there is a lot of humidity in the air. If not simply rinse it too with clean water.

Answer 4

Seer Ratings Chart

Answer 5

The model of your air conditioner is actually 38CK, the rest is probably the serial number. From what I'm finding, the SEER rating is 11.5.

Answer 6

Fyi, Carrier units, from what I have seen, are farely good units. They have manufacture warranties. The unit you have is a 3 ton unit (36 in your model number / 12 = 3)

Answer 7

Carrier's brochure says that this unit has a SEER of 10.0. See my source.

Answer 8

contact your carrier dealer for proper answer
