Got home and my AC isn't working

[NickTheGreat]

I’m trying to think how that is possible. Do you have the old wing windows for the front doors in addition to the standard door windows?

I can imagine 5/70 AC but 6/70 is blowing my mind.

Sorry, I drive a pickup, so I have the four door windows, sliding rear and sunroof.

4 windows down going 60mph

Old joke for me that I thought was somewhat commonly known, guess not.

I knew it.

I wasn’t even thinking of a sun roof. Touché.

I pretty much have my fan run 24/7 all year round. Keeps the air moving and temp more consistent in different rooms. Lots of high ceilings and vaulted ceiling so also keep a ceiling fan running on low in main living room. You don't notice the fan, it's like 13' high above the floor. Mostly finished basement and it keeps the air moving down there to so it never feels damp. Bought a pretty nice fan, not a big box store one, it's been running almost constantly for 20 years. That's a good motor in that unit!

I’ve thought about how to identify the proper fan run time; I have no idea.

I just know I hate hearing my AC run almost constantly during the summer.

I currently run the fan 30min an hour.

The newer ACs run more often but use less power.

My thermostat has a "recirculate" option that periodically turns the fan on when it's not on call but I just leave it run.

Good to know. My system was installed in ‘17 and the furnace is serviced every September and the ac every April.

I have no idea the technical term but I call it the helicoptering effect. I just open the back truck window and it goes away.

Buffeting (nothing to do with Warren).

You got Nate Stanley's attention.

It's my personal belief if you are to the point you're seeking advice on CF, You're already ******.

AC went out last week and had the capacitor replaced the next day. System is 17 years old from when we built. Looking at replacement now as small cracks were found in the heat exchanger when they checked out the entire system. Cost to repair all is $2-3k. New system around $12k (more efficient) but reduced $1,200 with federal tax credits (our kids and grandkids to eventually pay). Wifey (no pics) doesn't like old things that break down so we will replace. (Not sure how I'm around yet.) The service tech and also another HVAC rep said to run the fan 24/7. Who would have thunk.

Service tech just left my house.

Woke up Monday to a frozen refrigerant line and compressor running nonstop. Got things thawed out and running again, but wanted to have it checked out fearing a leak somewhere (or worse).

Decided to go the cheap route for now, recharged the system with 3 lbs of coolant (old version = expensive) and replaced a valve in the outdoor unit that may have been leaking by. No other obvious signs of a coil leak or other source of problem. ~$700 including tune up.

System is 17yo and hoping to limp by. We keep it set at 76 on the summer but get pretty uneven airflow between levels (ranch home). I've messed with damper positions as well as keeping the blower running to try to help.

Adulting is fun

Apparently everyone could afford their AC bill so far and hasn’t had to barter like I see in the movies all the time.

hopefully that works out for you, but your best bet probably would’ve been to just get a whole new rather than spend $700 and hope the leak is fixed.

Yep better bet to get a new one. Those heat exchangers are super expensive to fix. 12 grand for a new system? Yikes.

This guy I know said he just paid 13k for a new furnace and AC.. Just an average ranch home. I hope that's not right. My Lenox is 20 years old and it won't be long. Edit-just remembered he had ducts cleaned out too at the same time so that added to the cost.

That seems like a lot but I don’t know much about it, I think our furnace and ac 4 years ago was about $6k.

$4500 2 weeks ago for just an a/c. 1200 square foot ranch, 2.5 ton unit. It was also a pretty simple install / replacement so I would say $13k for heat and a/c probably isn't out of line.

i'm officially looking into mini-splits
