I think Sunshine and Munns are probably the two best large HVAC companies here in the Villages. There are other smaller family owned companies which are good as well.

When I purchased my Carrier Infinity Greenspeed system, since I knew the basic variable speed inverter technology was around for 10 years or more, this is the same technology in the mini splits everyone is buying these days, I wanted a company that was installing a lot of these systems so I knew I had a good chance of getting a great installation and competant service over the life of the product. Also, from experience, it pays to spend a little more with a company who is a major dealer in the brand of system you intend to purchase.

Many rate their favorite company on how fast they came at their time of need and that's totally fine but beyond price, the quality of the installation is probably the most important aspect since it will be a major factor in the longevity of your system.

I just discovered as of 1/1/2025 if you want a Carrier Heatpump or single AC system, they are not making the multi stage systems any more. You can only get a single stage or variable speed inverter system. From what I read, Carrier is streamlining their offerings now that the Variable speed inverter systems are more common place.

Per Carrier:
Carrier has not stopped making multi-stage heat pumps. While they have introduced a new fully variable Infinity Greenspeed heat pump model, they still offer two-stage and multi-stage options like the Performance 17 2-Stage air conditioner,

Here's a more detailed explanation:
Two-stage and multi-stage heat pumps are still available:
Carrier continues to offer two-stage heat pumps, which provide consistent comfort and energy savings.
Fully variable heat pumps are also an option:
The new Infinity Greenspeed heat pump offers a fully variable speed compressor, providing even more precise temperature control and efficiency, according to Carrier.

"Five-stage" line is discontinued:
The previous five-stage heat pump model has been discontinued, but the overall multi-stage options are still available.
Focus on efficiency and comfort:
Carrier is emphasizing the benefits of multi-stage systems, such as improved comfort, energy savings, and humidity control.

I just got an estimate from Sun Kool for the Carrier Infinity Greenspeed 4 ton. $14,951. The same in a 3 ton from Sun Kool $13,146. Manual J is the industry standard for sizing a heat pump. There is free software on the internet like CoolCalc Manual J .

The salesman claimed to me I would save 35% on my heating and cooling portion of my energy bill, not on my energy bill. I spent $103.00 on cooling in June and in October I spent $8.00. This is according to SECO. In the winter months I may not even turn the heat on.

Rule of thumb, The monthly savings per 1.0 unit increase in SEER = 15.6 kWh × $0.14/kWh = $2.20 per month. My present Carrier installed in 2009 is 15 SEER so if I go to a 20 SEER $2.20 X 5 =$11.00 per month. X 12 = $132 per year and for 10 years $1320.00. Is that on the low end or on the high side? I hope that is on the low side.

Sounds good! What is included with that price? Surge protector? Over/under voltage device? Air filter cabinet? Any other details on what they are doing for that price? Also, are you sure the new unit is 20 seer? From what I can see the 3 and 4 ton units are 23 SEER. What is the model # of the condenser they are estimating?

The one thing I don't like about the Infinity System is the Thermostat. Actually I have watched a few videos on it and if it does all it shows in the videos it is a great T-stat. But the communication protocol is proprietary and it is the only Thermostat that will allow all the features of the Infinity System to function. Ecobee makes one that will work but all the features of the system are not available.

All good just we all got the 27vna03 which is 24 seer. Not sure why carrier has both systems.

You got a deal Congrats. This is the one they quoted for me.

From the Carrier web page:

Description

27VNA036A003
27 = Puron Advance™ (R-454B) HP / Refrigerant & OD Type
V = Variable Speed / OD Design type
N = Infinity® / Tier
A = Initial Series / Major Series
0 = 20 SEER2
36 = 36000 Btuh (nominal) / Nominal Cooling Capacity
A = Standard HP / Variations
0 = Standard / Feature
0 = Not Defined / Open
3 = 208/230-1 / Voltage

So Carrier makes 3 infinity systems, 27VNA0 which is the 20 seer system, 27VNA1 which is the 21 seer system and the 27VNA3 which is the 23 seer system. Other than efficiency, they look identical. My guess is they are offering you slightly different efficiencies for more price selection in this series.

Let us know if you go for this system.

I'm not sure on the SEER efficiency savings but so far, I'm saving about $50/month over my single speed basic 15 Seer Carrier system installed circa 2016. Your savings will also depend on what temperature you set your thermostat to for cooling and heating and the size of your home.

Put in a Trane 4-ton Variable speed system 4 years ago. We also did a 4-zone system. Zoning added almost $4K to the price. I believe we have saved close to $4K to date as this system is extremely efficient. I say that because our SECO bills in the heat of the summer are just a touch over $100. Last month $107 and projected for this month $113. 2100 sq ft home. Average temp setting in home, 77 per Trane app.

That's a great system! It's good to get some real savings numbers. Thanks for the feedback.:BigApplause:

Yes, it is amazing for sure. This system rarely runs over 50%. At this moment on a hot 92-degree midafternoon, it is running at 28%.

Same here. My system usually runs at 45-50% even in this very hot humid weather.

After reading more and more about electric rates going to increase over the next couple of years, the tarriffs increasing the pricing of all HVAC systems, and the Federal tax credits going away this year, I'm sure myself and my neighbors made the right decision replacing now with the full 10 year parts and labor warranty vs waiting a year or two and paying a lot more money for these high efficiency systems. Especially since we use A/C most of the year when electric goes up, everyone is going to be scrabling for a higher efficiency system.

I remember my neighbors laughing at me re-painting my home before paint went up in price then two years later they were all paying almost double what I paid for the same job and paint!

Coming down soon for the design meetings when all the options will be finalized. Do we get the option of choosing different HVAC options like single speed vs variable speed, etc? I am very concerned about the humidity control and the possibility of mold... The comments about the variable speed running on humidity control mode makes me feel comfortable

When I asked my sales rep if this was an option she simply sent me a sheet detailing the " base" default option. So I'm really hoping that this is an option I can upgrade at build time
