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.
Most people I know that have replaced both in the last couple years have been anywhere from 10-14k so I'd say that probably isn't an unbelievable cost.

i'm officially looking into mini-splits

That was one of the first things I had installed when I bought my house in the PNW (no AC). While it was expensive, I think it was worth it. I haven't used it a ton, and have a gas furnace for the winter.

It's super nice to be able to only run the AC in whatever room I need/want. The main living space of my place rarely needed the AC run (east facing with the garage and 1/2 bath facing the west), while my upstairs always seems to roast and be about 5-10 degrees warmer. Throw in the fact that my furnace/air handler is upstairs and my thermostat is downstairs in the living room and I'd have to turn the first floor into a meat locker to get the upstairs to cool off (the inverse is true in the winter).


Oh, and 1940s houses in the UP of michigan suck to live in when it's 90 degrees outside. Friggin bedroom was 83 last night and the first floor was 78. Guess who's buying a window unit tonight?

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.
Eh, the way I see it is a repair cost of about $530 (3 lbs of R-22 into a 7 lb system, and some minor parts) to avoid a $4500 replacement was worth a shot. Likely a very small leak if still present as there are no obvious signs in any visible part of the system, and the recharge restored the expected temp drop across the cycle. All other mechanical and electrical components tested out fine.

Current R-410A refrigerate is banned for new systems beginning in 2025. Both HVAC guys I talked to said expect a 20% price increase. Yikes. We are replacing before then.

The $12k deal I was quoted was a 97% 2 stage NG furnace and two stage 16 SEER AC along with a whole house humidifier. Except on the hottest or coldest days it will run longer on the lower stage which is quieter and more efficient along with having better air quality and more uniform temps in the house. Talked to another HVAC guy today and didn't like 2 stage systems. More expensive and more things to go wrong. We'll probably go 2 stage.

Trane S9V2B080U4PSBB furnace
Trane 4TTR7036A1000B ac
Trane thermostat
Bradford White 40gal water heater

After discounts (yearly service, Trane, pay by check) it was $10,302

If your system was built properly with sufficient cold air returns, you can balance your registers. By leaving your furnace fans run 24/7 you should be able to make the temps fairly uniform throughout the house. You can do this by trial and error or a technician should have the tools/knowledge to do this for you.

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.
One of our NVH engineers gave a presentation on it a few years back. It's actually the air flow and associated cabin pressure change hitting a resonant frequency of the cabin. Fiddling with window positions and/or speed usually fixes it.

Seriously, is nobody going to make a quip about how BWRhasnoAC has no AC?

Come on people, such wonderful low hanging fruit.
But does BWR have AC now?

Seriously. I lived in the B.

Ask me about the redhead who gave my roommate a back rub…and insisted on doing it topless.

Anyone else here know this story?

When my AC broke down last summer, I thought I could tough it out for a few days, but sleeping in that heat was brutal. The humidity worsened; you can never cool off, even with fans going. I called a repair service because I didn't have the tools or patience to figure it out myself. It cost a bit more, but it was worth not dealing with constant sweating and migraines from the heat.

Look into reliable commercial HVAC services here: https://airflowac.com/commercial-hvac-services/ . They are profesional and very reliable.
