Ameristar Air Conditioners Buyers Guide – HVAC Brand Review

| Last Updated: February 12, 2021

Every property owner had to at some point considered investing in quality HVAC equipment. It is a decision that is only made once every few decades. This level of long-term commitment can have consumers feeling lost in a sea of options.

Ameristar is a household name that has been in business for over a century.

This article will talk about the pros and cons of buying an Ameristar brand furnace or heat pump.

The Best of Ameristar

Ameristar holds the reputation for being one of the most affordable and reliable companies to deliver HVAC systems. A brand supported by the parent company Ingersoll Rand, Ameristar is the budget version of Trane, also owned and operated by the same parent company. This gives a clear indication of the high level of quality, despite the affordable price.

Ameristar features an impressively comprehensive range of budget HVAC systems that suit a variety of climates. Products include air conditioning systems, heat pumps, and two-in-one solutions for temperate climates that fluctuate throughout the seasons. Their products are suitable for both gas and electric homes while boasting compact footprints. This compact footprint means little disturbance in the home, making their products suitable for those with smaller houses or apartments. With anti-rust technology and a 5-year base warranty, investing in Ameristar HVAC products demonstrates the epitome of good value.

While most budget-friendly products tend to utilize cheap parts, Ameristar prides itself on the internal scroll compressors that dominate their technology. Compared to other companies that market low prices, Ameristar's scroll compressor technology outstrips the capability of other conventional compressors. Not only are their scroll compressors far more energy-efficient than most other technologies, their smooth running makes them extremely quiet, therefore negating the chance of disturbance in the home.

When it comes to energy efficiency in particular, it is not uncommon for budget HVAC systems to fall short in this area. This often negates their low cost, as homeowners are forced to pay high energy bills. However, Ameristar has managed to develop products with excellent seasonal energy efficiency ratios (SEER). Where standard energy efficiency is scored at 13, Ameristar offers products that match or surpass this capability. For example, Ameristar's ductless systems come with a 15 SEER rating as standard, but are available with a rating up to 22 SEER. Equally, Ameristar furnaces, which work with either propane or natural gas have an Annual Fuel Use Efficiency (AFUE) of 95% compared to the standard efficiency of 79%. This not only provides a cost-effective option for purchasing the HVAC hardware, but also reduces energy outgoings throughout its lifetime.

In terms of peace of mind, Ameristar HVAC products come with incredible warranty programs. All products come with a 5-year base warranty, with a 10-year limited parts warranty if registered within 60 days of installation. On top of this, their furnaces come with a 20-year limited heat exchange warranty if registered within the 60-day period.

The Drawbacks

One glaring problem with Ameristar products in terms of budget-consciousness is that while the parts may be under warranty, the Freon and labor repair costs are not. This means that when problems arise, customers often report having to pay between $800 and $1100 to repair the issue. It is important to note, however, that poor installation can sometimes be the cause of these issues.

The second issue is that the parts are made in China and therefore, are difficult to acquire or may take a long time to deliver. In general, problems with HVAC systems are noticed when they need to be used. So, waiting 3-4 weeks for replacement parts can be frustrating. While there is a warranty on the parts, customers have complained that this warranty exists to cover the lack of reliability, with furnaces and heat pumps in particular failing after 18 months to 2 years.

Lastly, while the products themselves are quiet when operating, the shutdown fan in their furnaces tends to make a loud moaning noise for 3-7 seconds. While this may seem like a fixable issue, this is standard for their furnace products. Many customers find this pretty frustrating.

How Does Ameristar Compare to the Competition?

In the presence of multiple well-known brands, it becomes quite tough to mark your position. Ameristar is known to offer quality products. Here we will discuss some of the major features that set Ameristar air conditioners ahead of its competitors on the market.


The biggest plus point of Ameristar air conditioners is the affordable price tag. Their models are relatively reasonably priced when compared to Trane, American Standard, or other counterparts. All of them are equally efficient at low prices, which is very attractive for budget-conscious people.

7 Sizes

Another significant quality of these air conditioners is that each model is available in at least 7 sizes i.e., 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, and 5.0 tons. The ultimate choice depends on the user, according to his needs and budget.

Space - Saving

These air conditioners are highly admired for their compact design. They come with relatively small cabinets and, therefore, are highly recommended for small backyards or small spaces.

Multiple Warranties

Another significant advantage of investing in Ameristar products is that they are backed by reliable warranties. You just need to register your product within 60 days, and even if you fail to do so, you can still enjoy a 5-year warranty.


All the products offered by Ameristar are constructed from galvanized steel, which is corrosion-resistant. Therefore, you don’t have to take your AC for maintenance frequently. Moreover, these ACs are painted with weather-resistant paint to make them capable of withstanding hazardous environments without any hassle.

Bottom Line

Ameristar heat pumps are excellent for milder climates. It draws from the ground or the air to keep a consistent, comfortable temperature in the home by both heating and cooling. Made from the same rust-resistant galvanized steel, these heat pumps are equally hardy while still only taking up very little room. The M4HP4018A1000AA model is one of the most highly recommended. The smallest model has a 14 SEER rating, takes up 25x28x28 inches and only weighs 1.5 tons.

The heat exchangers, which have an optional 20-year warranty, are made from aluminized steel. This makes them both durable and efficient conductors of heat. The furnace cabinets are constructed from galvanized steel to prevent rust and to increase hardiness. Furnaces are available both as single-stage models and variable speed models. The M951P040BU24AAA is an incredible compact option for those on a tight budget. This highly-efficient model produces 40,000 BTU/hour.

Bottom Line

An all-rounder with top-notch features, this model is built to last a long time. Not only is the design appreciable, but the construction quality can’t be questioned. This air conditioner is corrosion-resistant, so there would be no tension of spending tons of money on frequent maintenance. The most loved feature is the quick conduction of heat to ensure a brilliant performance.

Easily operated on natural gas and propane, this AC circulates cool air and provides you with a nice environment throughout the year.

  • Customer service needs to be improved

Why it Stands Out to Us

Ameristar is well-known for offering some fantastic products, and this model is no less than other products from the company. Whether we talk about the design or reliable features, this model won’t do you wrong. The steel construction is meant to last a long time, and the cabinets are completely corrosion-resistant to enhance longevity.

Similarly, there is an efficient heat exchanger to give a comforting environment whenever you want. There is an incorporation of a scroll compressor that is highly capable of offering superior cooling efficiency while cutting down on your monthly bills. Lastly, you get to enjoy a comfortable environment in your house, thanks to the multi-speed blower.

Alternatively, for those looking at a gas/electric packaged unit, the M4PG3036A1064AA is a great model to choose. Slightly larger, it measures 41x45x57 inches. Gas/electric packaged units tend to be slightly less energy-efficient in the winter. This model has a 60,000 BTU rating. This models SEER rating sits at 13.

Bottom Line

If you are looking for an efficient air conditioner to provide you with comfort and efficiency, then look no further. This AC from Ameristar has got everything you have been looking for. It has a tubular design with an increased surface area, which is highly efficient in incredible heat transfer.

This model employs a scroll compressor, which is known to be more efficient than the less-advanced rotatory compressors.

  • Incorporates a scroll compressor for smooth operation
  • With 13-SEER efficiency, this model has a great construction


  • Horizontal installation only
  • Installation might take time
  • Comes with a limited warranty

Why it Stands Out to Us

This air conditioner from Ameristar has gained a lot of popularity among customers due to its brilliant and efficient design. It is manufactured from heavy-duty steel, which is galvanized as well to make it durable. Similarly, the corrosion-resistant cabinets save you tons of money.

Coming to the exceptional features, it has a scroll compressor which is quite smooth in operation and far better than conventional compressors. Moreover, you don’t have to worry about any noise production, thanks to the efficient fan. Overall, this model is highly capable of providing you with comfort and efficiency throughout the year. What else could you ask for?

For those looking for a simple year-round answer, Ameristar packaged units offer a two-in-one solution. Available both in a gas/electric option or as a heat pump option, the high efficiency of the compressor ensures that energy bills are kept to a minimum. Ameristar packaged units are architecturally designed to reduce their footprint in the household, while remaining robust throughout the years on account of their anti-rust technology employed through the use of galvanized steel. While the units can come with either rotary or scrolled  compressors, the better scrolled compressor technology is harnessed in the M4PH3036A1000AA model. This model works with a heat pump and has an excellent BTU rating of only 35,420, showcasing its extraordinary efficiency for such a budget-friendly double package of heating and cooling.

Bottom Line

A highly versatile and easy-to-install air conditioner, this model is incorporated with a range of remarkable features. First of all, the design is very attractive and compact as well, making it highly suitable for closed spaces. Similarly, the sturdy build is corrosion-resistant to bring value to your bucks.

This model features 13-SEER and can be easily installed in a horizontal position. Moreover, the scroll compressor with a multi-speed blower keeps the noise almost negligible. With this air conditioner on board, you are likely to save tons of money on monthly bills and get to enjoy a relaxing environment whenever you want.

Other Options

When looking for ductless systems for those without central heating configurations in their houses, Ameristar provides extremely efficient and affordable options. They can be used in houses without duct systems or for zones within those buildings which are not reachable by the ducts, such as garages. While there are both single and multi-zone 15 SEER options, providing outstanding energy efficiency, the most impressive model is the 22 SEER model. This 115-volt model provides a low-cost heating and cooling system.

Ameristar air handlers will help to circulate air around the home. This makes them an integral part of an energy-efficient system that provides an even spread across the home. Ameristar air handlers feature painted, galvanized steel insulated casings that prevent rust and reduce the noise output. Featuring three fan speeds, the M4AH4025A1000AA model weighs only 2 tons and measures 46.5x20x22 inches.

Finding the Best Prices

To find the best prices on HVAC units, particularly Ameristar units, looking on depot websites will help you to find great deals at discounted rates. In particular, websites like New AC Depot and CFM equipment will provide these low prices.

However, in order to get the best from your Ameristar HVAC products, they must be installed by a high-quality HVAC installer or contractor. Finding a local installer will help to reduce the costs, but ensure that they have either specific Ameristar training or training with Trane products. Trane has the same parent company and therefore, the components and installation are extremely similar.

Moreover, while buying HVAC products online may reduce the cost, a licensed HVAC professional trained in Ameristar products will be more qualified to outline exactly what you require, providing you with the most efficient and cost-effective solution. Otherwise, you may find yourself buying components that appear cheap but do not make sense for your household requirements.

For those worried about budgeting, it is important to make yourself aware of the tax credits system. Tax credits are assigned to help those with lower incomes to afford HVAC systems from their home. For air-source heat pumps, a tax credit allowance of $300 is given to low-income households, while $300 is given for central air conditioning and $150 for furnaces. The information regarding this and the stipulations of the HVAC systems this applies to, can be found on the Energy Star government website.

What Kind of Warranty Does Ameristar Offer?

Ameristar has been a popular brand in offering multiple heating and cooling equipment. Manufacturers offer a certain warranty on their products in order to enhance the confidence of the customers in their products. Ameristar products are also backed by some limited warranties to ensure a reliable purchase.

5-Year Base Limited Parts Warranty

One of the warranties offered by Ameristar is limited for 5 years, and covers damaged base parts. This type of warranty is applicable for residential use only, and the company has the right to apply certain restrictions. You are recommended to ask your installer about other warranties in order to make an informed decision.

10-Year Registered Limited Parts Warranty

This type of warranty works only if you register your products within 60 days of installation. Otherwise, you won't be able to enjoy this warranty. It lasts for 10 years and covers the damaged parts to serve customers efficiently.

20-Year Limited Heat Exchanger Warranty

Another warranty offered by Ameristar covers any damage caused in the heat exchanger. However, the criterion is the same. You need to register the product within 60 days of installation in order to make this warranty work.

You can easily register your products online at or by calling 866-554-5611 to enjoy the above-mentioned warranties.

Company History

Ameristar was formed by Ingersoll Rand, a Dublin-based billion-dollar company. Ingersoll Rand was originally formed in 1905 from Ingersoll-Sergeant Drill Company and Rand Drill Company merging. These two companies had formerly been rivals, individually formed in 1871. They now stand as a top global diversified industrial manufacturer.

Despite Ameristar’s Irish heritage, Ameristar furnaces are made in Trenton, NJ using the same standard process and design as Trane furnaces. The rest of Ameristar’s product line is produced in China, that includes their heat pumps and A/C units. They also have a US operational headquarters in Davidson, North Carolina.


Ameristar is an excellent choice for those looking for budget-friendly HVAC systems. Not only are they initially low-cost, they provide competitive energy efficiency to keep the resulting energy bills low. 

While they cost a similar amount to install and repair as other systems, they are generally reliable and appear to be a solid choice, especially for those looking to use tax credits.

    • Hi,
      You could be in a really wide range depending on your location and brand. Not sure if you mean specifically for this brand. The SEER rating also affects the price a lot, and the requirements for that can vary by your location, too. But I’ve seen Goodman units – which is a good brand – starting at around $2700 for 5 ton units, but that’s 14 SEER. Better SEER ratings are going to drive that up
