Don’t have time to read through countless Ameristar AC reviews? Here’s a quick breakdown of my favorite Ameristar units for cooling (as well as one to avoid):
Ameristar air conditioners – Quick guide!
A4AC5 Air Conditioner
The A4AC5 is my all-time favorite Ameristar AC because it offers the highest SEER out of all the Ameristar cooling products. Thanks to its SEER of 16, you could see up to 38% energy savings per year.
M4AC5 Air Conditioner
Because of its mass-production status, the M4AC5 is an extremely budget-friendly option for homeowners. Unlike the other budget-friendly A4AC3, this one has a more impressive SEER rating of 14.3, so you could experience up to 34% yearly energy savings. I often recommend this unit to people who have rental properties.
A4AC3 Air Conditioner
I don't see the point in buying the budget-friendly A4AC3, considering you'll spend more annually on energy costs. Sure, you won't have to pay as much upfront for this less-efficient 13.4 SEER unit, but the yearly costs will add up quickly.

Although Ameristar may not be as well known as major brands like Trane and American Standard, it’s still a force to be reckoned with when it comes to efficiently cooling your home, and I install their units regularly.
In my complete guide to Ameristar air conditioners, I'll cover everything there is to know about this brand's AC units, including what to expect regarding SEER ratings, noise levels, cost, and the pros and cons of each model.
My review of Ameristar air conditioners
As you browse Ameristar's online selection of air conditioning products, you'll notice that there aren't many models to choose from, far fewer than other lines like American Standard and Goodman.
That's because the company believes in quality rather than quantity, especially when it comes to energy efficiency.
There are currently 4 models in production under the Ameristar name, including:

Pros & cons of buying an Ameristar AC
As with any brand of air conditioners, Ameristar HVAC isn’t perfect. These units have advantages as well as downsides. This is the list I like to share with clients.
The good
The bad
Ameristar air conditioner prices – How much do they cost?
Compared to other brands and competitors, having an Ameristar unit installed by an HVAC technician isn’t likely to break the bank.
In other words, the upfront cost of Ameristar cooling equipment won’t require you to take out a loan!
The affordable line often surprises my clients, especially because Ameristar is partnered with Trane and American Standard, which aren't known for their budget-friendliness.
Still, Ameristar was founded with budget-friendliness in mind, and the company has certainly delivered on that.
Pricing by model
Below, I've included a chart with all current Ameristar models and pricing expectations with and without installation.
Remember that these numbers fluctuate based on a contractor's installation costs and fees, your region, and the time of year.
Ameristar Model | Cost Without Installation | Cost With Installation |
|---|---|---|
A4AC5 | $2,100 - $3,600 | $4,000 - $5,750 |
A4AC4 | $1,750 - $3,000 | $3,800 - $4,750 |
A4AC3 | $1,500 - $2,750 | $3,500 - $4,600 |
M4AC5 | $1,700 - $2,900 | $3,600 - $4,750 |
Running costs explained
Because Ameristar units aren't the most energy-efficient on the market, you can expect the average cost of running your appliance to be slightly higher than that of more energy-efficient competitors.
There's no way of knowing exactly how much you'll spend on cooling each year since it depends on a few variables.
Don't worry; I won't bombard you with complicated math equations to determine annual energy costs.
Instead, here's a quick breakdown of the average running costs for each available model:
Ameristar Model | Average Yearly Running Costs |
|---|---|
A4AC5 | $425 - $500 |
A4AC4 | $530 - $675 |
A4AC3 | $575 - $700 |
M4AC5 | $425 - $550 |
Cost variation across US states
The cost of cooling your home depends on a few things, like your location.
I quickly came to realize this after moving from Ohio to South Carolina.
It costs significantly more to cool my home in Charleston than it ever did in Cincinnati, Ohio. This is no surprise, considering SC is a much warmer state throughout the year—although I was still surprised when my first summertime electricity bill came in the mail!
If you live in a southern or southwestern state that remains warm throughout the year, you'll want to expect higher costs—not only with your energy bill but also with the initial cost of your unit.
There's a higher demand for cooling in warm/hot states like the Carolinas, so HVAC companies and AC manufacturers can charge more for their products.
How to get the best price in your area
While shopping in another state to get a better deal isn’t really an option, there are a few things you can do to ensure the best price on your next Ameristar unit.
I'm not a huge fan of negotiating and haggling, but trust me when I say you are more than welcome to negotiate on the price.
HVAC pros tend to high-ball customers to get the biggest payout, so even if you're able to knock a few hundred bucks off the final deal by negotiating, they'll still make a profit.
Next, it's all about timing. Buying your AC in the heat of summer means you'll be paying a higher price due to the higher demand.
I purchased my home's Ameristar A4AC5 in September when the temperatures started to drop. And guess what… the price dropped, too!
Here are a few more tips for getting the best deal on your next AC unit:
Model | Price* (w/out Installation) | Price* (w/ Installation) | Estimated Running Cost** | Government Tax Break |
|---|---|---|---|---|
A4AC6 | $1950 – 3400 | $3950 – 5400 | $400 – 490 | $300 |
A4AC4 | $1675 – 2800 | $3675 – 4800 | $510 – 625 | - |
A4AC3 | $1400 – 2500 | $3400 – 4500 | $550 – 670 | - |
M4AC6 | $1625 – 2750 | $3625 – 4750 | $410 – 500 | $300 |
M4AC4 | $1300 – 2400 | $2300 – 4400 | $520 – 640 | - |
M4AC3 | $950 – 1890 | $2950 – 3890 | $560 – 685 | - |

Features of Ameristar units

Energy efficiency/SEER rating of Ameristar AC units
Whether you're looking into central air conditioners, window units, or an Ameristar furnace, the SEER rating of the appliance will tell you what to expect for efficiency and yearly running costs.
The higher the SEER, the better the efficiency and the lower the running costs.
Honestly, Ameristar isn't a frontrunner in producing efficient units. Its most efficient unit scores a 16 on the SEER scale, whereas brands like Trane and American Standard have 20 SEER models available.
That being said, a rating of 16 is still perfectly adequate, and the affordability of each unit justifies the slight lack of efficiency.
In fact, the ideal pricing model of Ameristar completely makes up for the not-so-ideal efficiency of the company’s AC units.
Just compare the price of the 16-SEER A4AC5 to the similar XR16 AC from Trane.
Both units have a similar 16 SEER, but I was able to purchase and install the A4AC5 for about half the price!
Ameristar compressor options
Ameristar currently only offers single-stage scrolling compressors.
While scrolling compressors are slightly more efficient than standard compressors, they are less efficient than modernized inverters and multi-stage compressors.
The good news, though, is that single-stage compressor systems are much more affordable than multi-stage compressor air conditioners.
While you may see less energy savings throughout the year, you'll undoubtedly spend less upfront for a single-stage compressor unit from Ameristar.
Condenser fan options
Along with compressor speeds, variable-speed fan motors can help maximize efficiency and keep the system at the right temperature to perform optimally.
Since Ameristar only has single-stage compressors, there is no need for multi-speed fans.
For this reason, you’ll find only single-speed fan options (on or off) with any Ameristar condensing unit you choose.
Noise levels
Noise is measured in decibels (dB), a rating system comparing the noise to absolute silence. The higher the dB rating, the more noise it produces.
If you're like me and prefer peace and quiet, it's best to find an indoor air quality system with a dB rating of 65 or lower (which is an arduous task).
Keep in mind that air conditioners aren’t the quietest machines, and they tend to produce a lot of noise.
Ameristar air conditioners offer average performance when it comes to sound levels, rating between 71 and 76 dB across the board.
For quiet operation, I recommend the A4AC5 air handler. Even at full force, the noise level will remain around 72 dB.
Ameristar air conditioner warranty analysis
Ameristar has two separate warranty policies: one for products that are not registered and one for products that are. Here’s a quick breakdown of each:
- 1Base limited warranty:
This policy goes into effect for units that aren't registered or were registered more than 60 days after installation. It covers parts that might fail due to manufacturer defects but not the labor to replace them. In most cases, this warranty lasts five years, but the length of coverage may change depending on the product. - 2Registered limited warranty:
This policy lengthens the term of your warranty if your product is registered within 60 days of installation. It covers parts that might fail due to manufacturer defects, but not the labor to replace them. In most cases, this warranty lasts for 10 years, but the length of coverage may change depending on the product.
Ameristar air conditioner models compared
Ameristar currently has 4 different air conditioning models on its roster.
While you can find other models available as well, these 4 are the only ones currently being produced by the company.
ACLAB Note:
Try to avoid ACs that aren't currently in production; I'm noticing increasingly that HVAC companies in my area will do whatever they can to get rid of these outdated models to reduce inventory, even by dropping the price significantly.
These models aren't typically covered by Ameristar's warranty, and they're less reliable than the ones I've reviewed below.
Model | Available Sizes (Tonnage) | SEER* (Efficiency) | Noise Levels** | BTUs | Compressor Speed |
|---|---|---|---|---|---|
A4AC6 | 1.5 – 5 | 16 | 74 – 76dB | 18000 – 60000 | Single-stage Scroll |
A4AC4 | 1.5 – 5 | 14 | 74 – 76dB | 18000 – 60000 | Single-stage Scroll |
A4AC3 | 1.5 – 5 | 13 | 74 – 76dB | 18000 – 60000 | Single-stage Scroll |
M4AC6 | 1.5 – 5 | 16 | 74 – 76dB | 18000 – 60000 | Single-stage Scroll |
M4AC4 | 1.5 – 5 | 14 | 74 – 76dB | 18000 – 60000 | Single-stage Scroll |

Ameristar A4AC5
Main features:
Like all Ameristar AC units, the A4AC5 utilizes a single-stage rotary compressor. The difference is that this is the most efficient model available from the company.
While 16 SEER may not sound impressive, it's enough to show plenty of energy savings and is even eligible for some major tax credits. I recommend an Ameristar air conditioner.
However, if you choose a larger 2.5-version of this unit, which is the one I have, it's built with a rotary compressor instead of the standard scroll design, saving even more money.
Ameristar A4AC4
Main features:
Next up on the docket is the A4AC4. I find this model to be reliable, fairly efficient, and affordable upfront.
Because 14.3 SEER rating isn't a stellar score, don't expect to see substantial energy savings unless you're upgrading from a much older cooling solution.
Similar to the A4AC5, the A4AC4 has a few options based on your specific size and coverage area needs.
I love that Ameristar offers different sizes for each unit, so no matter the space you have available, you're sure to find a version of the A4AC4 that works for you.
Ameristar A4AC3
Main features:
The A4AC3 is an adequate cooling solution for anyone on a budget.
With a 13.4 SEER rating and single-stage compressor speed, it gets the job done, but don’t expect much else.
I only recommend this model for those who are on an extreme budget and can’t afford a more expensive model from Ameristar.
Another thing to note about the A4AC3 is that it ranks higher on the decibel scale than the previous units.
It has a 76-dB rating, which isn't much louder than the 71-74 decibel output of the A4AC4 and A4AC5 models, but it's still enough to make a difference.
Ameristar M4AC5
Main features:
The smallest model available at Ameristar is the M4AC5, which is great if you’re limited on outdoor space for your AC.
I love this appliance for several reasons; not only is it affordable upfront, but it’s also extremely efficient, especially considering the low initial cost of installation.
After comparing pictures of the previous model to this one, I immediately noticed that the M4AC5 uses different exterior parts.
That's because these parts are mass-produced, which is a good thing if you ask me. After all, they're more readily available if repairs and replacements are ever needed.
Ameristar installation explained for homeowners

An improperly installed system is the number one reason for warranty claims, repair needs, and inefficient operation.
That's why I always leave the installation of any HVAC appliance to the professionals.
Even if you think you can save money and successfully install your AC unit on your own, I don't recommend it.
This type of job requires specialty tools and knowledge, and it's not a task that can be deemed DIY-worthy.
Most contractors and HVAC companies list prices including the cost of the unit as well as the cost of installing it.
However, the final price can vary based on your location, the specific model you’ve chosen, and the professional’s level of expertise.
Before actually installing your new AC unit, ask the installer to perform a home visit.
I don't love the idea of strangers coming into my home but trust me when I say that it's worth it to have a preinspection before installation day.
After this visit, you should be provided with a detailed cost estimate for the upcoming job of installing your Ameristar.
Remember, there are a lot of factors that can influence the final cost of the job, including:
The Ameristar brand at a glance
Ameristar originally started under the Ingersoll-Rand name, which formed in Ireland in the 1870s.
However, the air conditioner market and the birth of the Ameristar brand didn’t take off until the production moved to New Jersey many years later.
After the move, Trane Heating and Air took over the AC side of the business, and production was primarily moved to manufacturing plants in China.
While the parts and pieces come from Chinese labor, most units are assembled in Texas or New Jersey.
With major partners like American Standard and Trane, Ameristar can produce affordable air conditioners and furnaces, heat pumps, ductless mini split units, air handlers, indoor air coils, and more.
Homeowner & buyer reviews
I’ve found that smartly buying any HVAC appliance is all about the research, and part of that research includes browsing through Ameristar AC reviews across the web.
While I certainly recommend these units for homeowners on a budget, don’t just take my word for it!
“I’ve had mine since 2017… A big plus about their units is the evaporator and condenser fan motors are regular motors without all the expense of the fancy variable speed motors. Motor cost $100-150 vs $500-1000.”
- Review from Reddit
"The 3 Ton Ameristar by Trane 15.2 SEER2 R410A Single Stage Air Conditioner Condenser is an incredible find! Its unbelievable price for top-tier efficiency and consistent performance is a surprising and exceptional solution for maintaining unparalleled comfort and energy savings in any home.”
- Review from National Air Warehouse
Of course, not all reviews surrounding Ameristar are positive, but it’s important to factor in why that is. As I scoured through both good and bad reviews, I found that most of the negative critiques had to do with improper installation, so I can’t stress enough the importance of hiring trusted HVAC experts.
How do Ameristar air conditioners compare to top competitors?
Ameristar vs Lennox
Lennox is a big name in the HVAC industry, and many people consider it to be one of the top three brands out there.
Similar to most big-name companies, Lennox products are reliable, efficient, and durable.
Because of their quality components, you can expect higher initial prices for Lennox appliances than Ameristar. However, better efficiency means more energy savings over time.
Overall, Lennox units have a solid reputation for being durable, corrosion-free, and long-lasting.
Some units have been known to run strong even 25 years after installation. While Ameristar products may not last 2 full decades, the initial pricing is much more appealing.
I’ve never personally owned a Lennox because of the high initial price tag, and even with the potential energy savings over time, I can’t justify the cost of buying one.
However, if you have the money to spend and you want to see some real savings throughout the year, this is a great brand.

Ameristar vs Trane
Although Ameristar falls under the Trane umbrella, these companies produce very different products.
Trane originally started as a commercially focused cooling solution, and even their new residential models are built with durable, industrial-grade parts that are built to last.
While Ameristar units still use good parts expected to last at least a decade, they aren't as efficient as their parent company's models and will likely need repairs and replacement parts sooner.
For initial costs, Trane is among the most expensive brands, whereas Ameristar is considered to be a budget-friendly solution.
As long as you’re OK with replacing your unit sooner and potentially dealing with repairs over time, consider one of Ameristar’s air conditioners.
I have had a Trane unit in the past back in Ohio, and I can honestly say that I had no issues with my AC.
However, my Ameristar A4AC5 has shown similar results, and I saved a lot of money by going with Ameristar this time around.

Ameristar vs American Standard
American Standard products are popular, and for good reason.
Even with a high pricing model, homeowners all over the country turn to American Standard for its insane energy efficiency and extreme reliability.
American Standard ACs, heat pumps, and furnaces rank high on the SEER scale compared to other major brands.
They perform well in hot climates, cool climates, and everything in between, so it's easy to overlook the high initial cost of buying an American Standard unit.
While you can definitely find an American Standard AC unit that's similar in cost to an Ameristar AC, American Standard is actually a parent company to Ameristar, and the cost of installation is higher with Standard.
To top it off, repairs tend to be more costly and time-consuming, mainly because American Standard uses its own parts, so replacement parts must come directly from them.
Personally, ease of repairs and maintenance is important to me, which is why I suggest going with a brand like Ameristar, which offers both parts and labor that are readily available.
