Do we have any members that are in the HVAC business? Our unit has been out for a while and it's getting hot. Whew!
Thanks in advance!

im in rock hill just south of Charlotte . where are you located @Sandman_NC
well if it is low 90s outside and 72 inside I would say its doing pretty good. as far as the ice cold one side of house , warm on other look at airflow ( dirty coil , dirty blower wheel , air loss from ducts or insulation on ducts missing or inadequate)My AC doesn’t keep up, currently 72 in the House.
One side of the house is ice cold, the other side is warm.
What can I do?
To add to what JJ pointed out how smart is your thermostat?My AC doesn’t keep up, currently 72 in the House.

Improper sized ducting from initial install most likely if all the supply registers are open. Any HVAC company can throw in a unit but can they engineer the individual rooms requirements?My AC doesn’t keep up, currently 72 in the House.

Indeed. There really is an art and science to it. It also costs money and these days it’s much cheaper to just throw some flex duct (which I’ve seen crunched down to a fraction of its size to get it through various openings as well as be bent 90 degrees) and one central return.Any HVAC company can throw in a unit but can they engineer the individual rooms requirements?
My god I want all my customers to be like you. This is what will scare off half the freaking jacklegs in this business. Low price usually means corners cut to make money. I’d rather call on a mechanical engineer than a Walmart shopper anyday.Indeed. There really is an art and science to it.

For my parents house that we’re building, that is thankfully almost done, I specified using rigid duct with a supply and return in the rooms (not in bathrooms or laundry room). The supply side duct is wrapped and it has a variable speed blower and multistage compressor. It’s really quite and cools/heats well. I went over the sizing and air flow calculations before approving it and had a test and balance specified for completion.
Close the duct to the addition off and install a Mitsubishi mini split or two.

Really you should get the heat and cooling load calculated. The numbers depend upon factors like type of lighting, exterior wall space, sun exposure, whether it's slab or not, etc. That being said, I just looked it up in the reference manual I have and it says that a one ton unit will cool about 550 residential sq ft if the wall area 25% glass and 700 sq ft if it is 15% glass (typical max for most walls per code in NC, at least when I built my house). So, you would probably want a half ton unit. Roughly speaking the charts also show you wanting about .6 to .75 cfm per sq foot too.@BlackGun How many BTUs for a 300ish SQFT?.

Go to the colder side Luke.

Yup, got one in our Data Center, gets so cold I fall asleep at the consoles.Second that!!! I had a Mit mini split installed in my shop last year, best money I've ever spent. If I'm not careful it get's cold enough to hang meat....
So face another crac unit towards it set on heat mode.Yup, got one in our Data Center, gets so cold I fall asleep at the consoles.
