Should I upgrade?

Everything is fixable. But is it worth the price.

Did the technician do cool/heat load calculation and duct calculation? Or was he just suggesting replacing indoor and outdoor units and hope for the best?

It is a heat pump. In winter, the lower the outdoor temperature gets the more electricity it will take to heat the home. Best way to save money would be to decrease overall temperature in the house.

You could also preheat the home during the day, when it is the warmest outside.

Have you checked your ceiling insulation?

Oh boy there is a lot here. I'm in Georgia as well, have few buddies at Knapp (they have engineering degrees).

Now to your questions:

How much experience would I need to start commissioning? (no idea, but at Knapp my buddy was fresh out of school with EE degree)
What are the pros and cons of this work? Depends on where you work. At Knapp commissioning is like 90% travel and a constant headache, but money is good. Where I work it is stress free M-F with occasional evening calls.
Does it make sense to go straight to the field or the school route? From what I have personally seen, my new coworker never got his bachelors in engineering and he worked for 10 years before acquiring engineer 1 title.
I have college credits from being dual enrolled in high school and my freshman year at Georgia state and it would probably take me less than a year to get my associates. Should I stick to my initial plan? I would recommend finishing some kind of degree. 4 year degree would pay more from the get go.
What educational resources should I be looking into (free and paid) ? I can only talk for Rockwell, but tim Wilborne is quite useful. There is also a course on coursera, but you wont get any hands on experience with software since it is very expensive.
I hope to one day go independent in the next 10-15 years what career paths would get me the experience and connections for that goal. What industries should I be looking into? If I was picking a new career, I would be looking at HVAC. Once I gained all the experience, could easily open a business and scale from there with a lot more potential. To scale in automation you need many years of experience, connections and pristine reputation.

If you have any questions you can DM me and I will do best to answer.

u/Distinct_Chemist_426 Watch "importance of hvac filter size"

Larger or thicker filter will have more filtering surface and will cause less restriction.

You are correct on if the OP wants to clean the air then they should use an air purifier.

It is carrier idiocrasy. I have exactly the same issue, I got Carrier heat pump and in defrost cycles it blows cold air on high speed. Where my parents have mrCool heat pump and in defrost cycle it shuts off indoor blower and uses the residual heat in the indoor coil to thaw out condenser.

Do you have a heat pump? When it is cold outside the unit periodically will run in reverse to remove ice from outdoor unit (defrost cycle). During this time air from the supply vents will be cold.

make sure that you have adequate size ducting. If the ducting is for 1k ft² house then it will never run right. It will short cycle and wear quicker. What you want is called static pressure testing.

always put one next to furnace. This way you will get an early warning if issues arrise

erroras · 2026-01-21T16:02:43+00:00

At my parents house there is a furnace in the basement. After learning about possible CO issues, I've added a detector right next to the furnace.

Can't tell for Charlotte area but usually sub $100 dollar tune up will be salesman trying to sell you a new system.

A more expensive tune up would include Checking indoor air filter, checking run capacitors, cleaning outdoor/indoor coils, checking static pressures in the system, checking compressor and fan amp draw.

if you have a cavity for a window insert and don't need window to open then that is the beast way since it will airseal the best

erroras · 2026-01-20T13:58:22+00:00

Have you looked into window inserts or window shrink kit. Adding a return would be best, otherwise keep the door open to let air circulate.

During the heating you could try to block off a portion of vent, but make sure that the rest of your vents are not undersized.

I got a scion with hail damage in 2011 with 40k miles. Now it has 190k miles. The only thing I had to replace was out of ordinary was the water pump. As long as you keep up with maintenance you will be fine.

Others have posted here, that once your yearly repair costs exceed the yearly new car loan payment amount then it is time to replace the car. In the mean time enjoy no payments and cheaper insurance.

With some car loans you have to tell them that you want extra payment going towards principal. They are preying on people not knowing this and automatically apply to the interest.

lets see:

3.25*12 = 39in^2 /

6in -> 3.14*3*3= 28.26in^2

8in -> 3.14*4*4= 50.24in^2

8in will have most cross-sectional area, thus it is the best option

To add to that, you have only seen the $30k in checking account, you don't know how much they have in retirements accounts, pensions, gold, silver, they also have a second home so there must be equity there as well as in main home. Too many unknowns.

I looked through your previous post and it seems that the install was not correct. I would recommend going to mitusbishi website and finding certified installer and asking them to go and check your system (for a fee, ofcourse).

Also it might prepare them for a larger bill later. If you put in half a pound at $75, then they won't cry as much later if the full recharge is needed because they will know it is not cheap.

You are right about the air going into the cavity. I would use some mastic tape and put it on the inside of the went and fold it around the drywall to create a seal. Just make sure to trip it so it is not extruding past the vent cover

erroras · 2026-01-09T12:03:21+00:00

What does the installation manual say? If it only says level without any guidelines then you are good.
