Are you an HVAC company or an independent professional?
Would it be possible for you to provide a quote?
We are planning to replace the 16-year-old Trane furnace and A/C in a 2 story detached house with 2200 sq ft.
I am currently assessing between 2-stage 60K (or) 80K BTU furnace.
2-Stage 2, 2.5 or 3 Tons A/C.
Please provide your suggestion as well.

- Reason for change: Evopratior coil frozen iced some years ago due to some rust and dust buildup clogged the mini drain. There was water leaking through the furnace so the bottom part of the furnace is rusted inside, on the floor as well. Before I learned the clogging reason, some time back Reliance came and checked asked us to change everything. But some other technicians suggested cleaning up the dust clogging periodically in summer to avoid the issue. It works ok but rusted all over.
- R22 was filled last year, it was almost empty. There may be leaking to figure out.
- A/C Parts were changed by service plan last year
- Furnace parts were changed many times, service plan covered.

So far no issue from Furnace last year, and A/C runs fine this year.

We may sell the house later this year or next year. Having a rusted Furnace may be an issue for buyers.

Regarding 2 stage A/C: The current A/C is 8 SEER, 2 tons. Specifically, in the summer months, hard to get coll to the 2nd floor, but it is ok when the A/C is running. For instance, 28-degree temp when A/C runs is comfortable. 25 Degree at home if A/C not running then it suffocated. it came 23 degrees, then if A/C is not running then again suffocated.
One thing I realize is that when the Furnace fan is running it gives some comfort by rotating air from the basement, 1st floor, and 2nd floor, it helps somewhat.
So, I am thinking if the 2 stage A/C runs at a lower speed with lower speed from the furnace then it solves the humidity and suffocation.

This is where I see what they explain in 2 stages A/C as runs longer at a lower speed. This is the main feature I want to have.

Many HVAC salespersons don't encourage this option, and try to show the less price of SEER 13 or 14 and suggest 2 stage variable Furnace is more than enough. I feel like they are just trying to complete their sale by showing a saving in price and sell the product sooner.

So, at this point, I am not particular about brands like Lennox/Trane/Carrier/or any higher end. Even I was thinking of Canadian brands like Napoleon and Continental. But they don't have 2 stages A/C.

No brands are important for me now, I just what to experiment with the 2-stage Furnace and A/C with whichever brand comes with a good price deal. I read about Keeprite and Tempstar, seems both of their variable-speed models are good. So, I am planning to go with this.
I don't feel that single-stage is good enough for varying summer temperatures. That's where I want to see how the HVAC innovation of 2-stage variable speed helps.

1. 2-stage cooling will make the second floor worse, stick with single stage.
2. Second floor not cooling well is has other causes. Based on your description, you could benefit from running the blower continuously at a low speed as well as balancing.
3. You need to get the G96CTN to get the real benefit of the variable speed blower if you buy keeprite
4. The minimum efficiency 16 years ago for cooling was 10, not 8.
5. The a/c brand absolutely does not have to match the furnace brand.

It is not a good idea to chase after a "good deal"; if the price is significantly below average, contractor is cutting corners on install and or using inferior equipment.


The differences between low budget and mainstream a/cs not significant when it comes to comfort, only build quality and noise level.
2-stage/variable speed furnaces different matter...
A good one will set you back $4k+.
The cheapened ones (like the G96VTN, goodman gmvc96 and lennox ml196v and all clones) should be avoided due bad blower programming or no support for 2-stage thermostats. Don't get full benefit but do get increased repair costs.
The 2-stage thermostat is necessary to get the full benefit, having high heat only come on when it is necessary - without it, high is brought on after a time delay, so you don't get very extended heating cycles.
The entire point of the variable speed blower over the multi-speed is to precisely maintain optimal airflow as conditions change (ie, automatically compensating for vents being adjusted, etc) in every mode of operation and the programming of the cheaper models do not allow for that functionality and can be even worse than more basic furnaces.

I noticed in many forums that many had difficulty getting Lennox parts. But, the Keeprite parts are easy to get it seems. As long as it runs like a Mitsubishi or Hyundai then I am fine.

Could you please comment on the 2 stages variable speed Furnace and the 2 stage A/C from Keeprite and Tempstar.

I am a person who looks value for money whereas others may be a die-hard fans of features that may not serve any purpose. When the furnaces were equipped with PSC motors, some common parts were universal like ignitor OR motor.
With new ECM technology, you cannot use universal parts regardless of the make and model. Most common parts are available with suppliers for any brands be it Lennox or Carrier.
There are situations when some specific parts are not available even for Goodman or keeprite.
To me complex machine means more chance of breakdown. Period. For the same reason, I always advise my customers to stay away from modulating furnaces and or communicating thermostats.

"Anywhere from $800-1200 and everyone wanted to install the S30 (thermostat)

Apparently the model I had was known to a few installers for failure. I emailed Lennox since it was past the 5 year warranty and they were no help.

I find it very frustrating that I have to shell out this kind of cash 7 years into a new HVAC system. I don't want to have to pay this again in 7 years. Lesson learned. Ecobee, Nest, and the other 'smart' thermostats cost a fraction (yes, they aren't communicating, but is it really worth 2-3k more over the expected life of the furnace?"
