Our builder put this unit in for us April 2015 and frankly had I known then what I know now I wouldn't have bothered. First, in November 2015 during a cold snap here in Delaware the heating part went out. Just quit. Put in an emergency call and was told that a board had shorted out and it would be replaced in a few days. Repairman did a "temporary fix". Took 3 months to get the part as it had to be shipped from China. Now in May 2016, on the very first day we used it this year and of course just 6 weeks out of labor warranty the ac quit. We are still waiting for them to show up to see what it wrong this time, but of course the labor will not be covered. I hate to think what it will cost us. I think this unit is a lemon and I am going to ask to have it replaced. Plus I was never told that in order to double my warranty on parts to 10 years I would have to register it online. All the paperwork was stuck to the side of the unit with no information given to us. So we are stuck with a 5 year warranty on this piece of junk. I don't understand why merely registering it online should make it a better warranty. Unfortunately if we can't get it replaced as defective we will be stuck having to purchase something else before the 5 years is up, or until it fails again at which time it will be immediately replaced. We have owned heat pumps in other houses and never, ever had these types of problems. UPDATE: 9/9/16 Wrote back in May about this unit. Now, in the middle of the east coast heat wave, the A/C has gone out. Contacted a different person to look at it and they tell us that we are totally out of Freon…I mean zilch. We decided to go back to the installer as we figure they can better deal with the warranty. He discovers that there is a leak in the coil inside. Plus also discovers that the insulation on some door is falling apart and blowing bits of foil everywhere in house. Charges us $195 just for the service call and says they will order the parts. Got a call yesterday and here's the kicker………only the parts are covered. So not only do we have to pay to have them installed, but they are charging us for the Freon fill and the freight to ship the parts! Another $900 on top of it all! $700 for the Freon and service and $200 freight. Unfortunately we are in a financial position right now that we can't replace the unit. And who knows how long it will be to get the parts in. If they have to come from China, which I would assume, it might be winter before we get them. I am so livid I could scream. I am considering contacting someone in consumer affairs in the government, the local investigative reporter, and a lawyer. There is absolutely no way that all the Freon could have leaked in the last 6 months. It had to have been leaking before the first year warranty period. Besides, with the number of problems we have had this unit is a lemon and should be totally replaced at the company's cost. Under no circumstances should anyone ever buy an Ameristar unit. Cheap builder's grade Chinese junk. Ingersol Rand should be ashamed to even sell these crappy units. The sad thing is that there are several people in this community with the same Freon leak problem and the contractor refuses to admit the units are junk. I only wish I could talk to everybody who comes in here to buy a house and let them know our experience.


A heat pump is your go-to HVAC option when you live in milder climates. They are designed to be a cost-effective option that has the dual purpose of both heater and air conditioner depending on the time of year. 

A new heat pump can demand quite an investment, so it’s important to find a brand that will deliver stellar performance without breaking the bank. 

This is where Ameristar shines. It is an economy line created by Ingersoll Rand, specifically designed to be a budget-friendly option for homeowners. 


Types of Ameristar heat pump

Ameristar offers three models for its heat pumps: M4HP3, M4HP4, and M4HP6. 

While some companies limit the sizes to certain models, Ameristar offers greater options with several sizes available for every model. All models are available in seven different sizes: 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 and 5.0 tons. This determines the model number for each of the three series.


M4HP3 Heat Pump Series

  • M4HP3018A1000AA (1.5 tons)
  • M4HP3024A1000AA (2.0 tons)
  • M4HP3030A1000AA (2.5 tons)
  • M4HP3036A1000AA (3.0 tons)
  • M4HP3042A1000AA (3.5 tons)
  • M4HP3048A1000AA (4.0 tons)
  • M4HP3060A1000AA (5.0 tons)

M4HP4 Heat Pump Series

  • M4HP4018C1000AA (1.5 tons)
  • M4HP4024C1000AA (2.0 tons)
  • M4HP4030B1000AA (2.5 tons)
  • M4HP4036B1000AA (3.0 tons)
  • M4HP4042B1000AA (3.5 tons)
  • M4HP4048B1000AA (4.0 tons)
  • M4HP4060B1000AA (5.0 tons)

M4HP6 Heat Pump Series

  • M4HP6036B1000AA (3.0 tons)
  • M4HP6042B1000AA (3.5 tons)
  • M4HP6048B1000AA (4.0 tons)
  • M4HP6060B1000AA (5.0 tons)

These machines use many of the same components as Ameristar’s sister companies, Trane and American Standard. However, a smaller design and shorter warranties translate to big savings.


Ameristar heat pump models

Ameristar offers single-stage models, which are known more for their affordability than their large heating capacities. Single-stage models only have one level for heating/cooling output (as opposed to two-stage models which have both high and low options).

All units offer 24V low-voltage control and are made of painted galvanized steel, so there are no worries about rust. This is an all-weather machine that can survive outdoors and boasts a small, compact design.

This what you can expect from each of the Ameristar heat pump series:

SeriesSizeSEER RatingHSPF* Energy EfficiencySound RatingVoltage Control
M4HP3 1.5 – 5 tons13 SEER7.70 – 8.2074-76 decibels24V

M4HP61.5 – 5 tons16 SEER8.20 – 8.5076 decibels24V

*Heating Seasonal Performance Rating

The size of your home dictates the size of the unit you need. For example, an 800 square foot home only needs a 1.5-ton unit, while a 3,000 square foot home would best benefit from a 5-ton unit. Newer homes also tend to be more energy-efficient with upgraded windows, insulation, and siding. 

With Ameristar’s heat pumps, you have limited SEER availability, with 13, 14, and 16 SEER only. The 16 SEER is only recommended for those living in warmer climates and all three pumps are loud at an average of 76 decibels.


Ameristar heat pump pricing

Ameristar heat pumps are sold through a third-party distributor, so the price can vary depending on where you live and who you purchase from. 

In January 2020, Amazon offers a 4-ton 14 SEER Heat Pump for $2,159.99 with optional expert installation for $150.00 per unit. The same product by National Air Warehouse is sold for $1,793.13 without installation. New AC Depot shows some Ameristar products on sale, featuring an Ameristar 1.5 ton 14 SEER heat pump discounted to $1,161.00 from its original price of $1,728.00.

However, the cost of installation can easily add $1,000 or more to your total bill. The installation cost for a basic heat pump ranges from $1,300 to $2,100.

There are additional costs you may incur, as well, which can include:

  • New or repaired ductwork, which can cost up to $5,000.
  • A condensing unit pad to raise your outdoor unit off the ground for $30-$150
  • Refrigerant lineset for up to $500
  • Air handler which can cost anywhere from $500 – $3,500

Thermostats are an additional cost and are available with programmable and Wi-Fi options; this can add anywhere from $25 to $500 depending on the options you choose.


Ameristar heat pump warranties

To keep things affordable, Ameristar units are offered with a shorter warranty than many of its competitors with just a 5-year base limited warranty for all units. 

But make sure you register your warranty in time: to qualify for the 10-year registered limited parts warranty, you must register the unit within sixty days of purchase, or you forego the extra coverage.


Ameristar heat pump reviews

An essential part of the buying process is gathering customer reviews. There is no better feedback about a purchase than people who have already bought a product and put it to use, so take the time to read through product reviews before deciding which heat pump is best for you.

At, we specialize in a well-rounded buying experience so you can make the purchase that is right for you and your family. That includes real user reviews, which you can use to explore available heat pumps from a consumer standpoint.

What Makes Ameristar Air Conditioners Stand Out From the Competition?

Ameristar air conditioner units have cabinets made of galvanized steel, which is resistant to rust and corrosion. This means that Ameristar units last longer even when installed outside and exposed to the elements. 

The Ameristar Warranty is only offered for AC units installed in residential homes. The Ameristar warranty has to be activated by registering the AC unit online or via the phone within sixty days after installation. The AC’s have SEER ratings between 13 and 16, which means they are a bit on the lower end and are thus less costly compared to other major brands.

How Do Ameristar Air Conditioners Compare?

Ameristar vs Goodman


Both brands make air conditioners with full louvered sides for better circulation of air. 

Both brands use galvanized steel cabinets with a powder paint finish to protect them from rust and corrosion that comes with exposure to moisture. They also have salt-spray protection to prevent corrosion even further.


Ameristar only has units in single-stage mode, while Goodman ACs come in both single and two-stage cooling modes.

Goodman offers an 18 SEER rating for the most energy-efficient model while Ameristar offers a SEER rating of 16 for its high-end models. 

Ameristar vs Trane


Ameristar and Trane are from the same manufacturer. As a result, Trane and Ameristar ACs have fairly similar designs such as full louvered sides. The durability of parts remains the same as they are all made of the same materials with the protection of the galvanized steel cabinets.


The SEER rating of the a high-end Trane air conditioner is higher than that of the Ameristar. Trane goes up to 22 SEER while Ameristar only has a SEER 16 rating for the most energy-efficient model.

Ameristar vs American Standard


Since the two brands are both produced by Ingersoll Rand, they generally have similar parts and designs. 


The Ameristar ACs sell at lower prices than the American Standard ACs. This is because most of the Ameristar units have lower energy-efficiency. The Ameristar warranty is 10 years while the American Standard warranty goes up to 12 years for the high-end models.

Ameristar vs Lennox


Both brands use aluminum coils in their air conditioners.


The Lennox ACs have higher prices than the Ameristar air conditioners since they have more complex features and are made for the high-end market. Ameristar ACs are meant for the entry-level HVAC market and thus have fewer exclusive features and lower prices. 

Lennox ACs have both single and two-stage controls while the Ameristar ACs only have single-stage cooling controls.

Pricing Comparison of Ameristar Air Conditioners

The table below shows the price points for different Ameristar ACs. It is worth noting that the prices differ between variations within the three tiers of Ameristar ACs. The installation prices differ depending on the installer. As such, it is important to enquire from three or four technicians to find the best deal.

Ameristar Air Conditioner Troubleshooting

Once in a while, your Ameristar AC will run into problems. If the fuse and the breakers are not working, you need help from an HVAC installer to look at the system and tell you the root cause. The fuse usually burns out.

If your AC is noisy, check the fan motor since it is prone to wear and tear and causes the production noise as it has to overwork to achieve the same rate of cooling as before. If it does not rotate smoothly, consider replacing it with a spare one.

If your Ameristar AC does not cool, check to see if the contactor is still in place. You can use a multimeter to check if the contactor transfers enough voltage to the condensing unit. Consider replacing the contactor if it is defective and breaks current continuity. You may also need to clean or replace the condenser coil.

As we have seen so far, Ameristar air conditioners are reliable and convenient. They are mainly entry-level ACs suitable for use in homes and small offices where noise levels have to be kept low. If you are looking for an air conditioner that is budget-friendly you should consider settling on an Ameristar AC since they all sell at lower price points and have lower installation costs compared to those of other brands.

Review of the Best Ameristar Air Conditioners

Moving forward, we have a detailed review of each of the above-mentioned models to give you enough information about the major features of each of them. Hopefully, it will help you find the right one for your demands!

Let’s get started!

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.

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.

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.

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.

Thread: Trane Vs Ameristar

I've installed a number of Ameristar units and overall I've been really happy with them. Yes the heat pumps are made in China, but frankly the quality of the units are a lot better than many of the units I see made in the USA. The biggest advantage to the Ameristar line up is that they are using copper tubed evaporator coils. Trane and many other USA manufactures have switched over to a cheap aluminum evaporator coil and these cheaper coils can cause bad odors in the home. The copper coils are naturally antimicrobial and I rarely ever see a problem with them. The ameristar cabinets are constructed well with heavy gauge steel, that is insulated and has a nice coat of paint. The heat pumps come standard with Copeland compressors, and crankcase heaters and whisper fans. These are features that are usually reserved for the higher end equipment made in the USA.

Many of the members of this site reject Amerstar because it's imported, but I personally keep an open mind. As an engineer I'm more concerned with the details of how well the equipment is made rather than who or where it's made. I personally think if you go with Ameristar and it's installed well, then you'll have a system that will work great for 20 years easily.

Ameristar is an economy line of three central air conditioners.

Its ACs are built with many of the same components as three of the most affordable Trane and American Standard ACs. All three brands are produced by Ingersoll Rand. The Ameristar air conditioners are marketed at a lower cost than Trane and American Standard. They give homeowners budget options.

This Ameristar air conditioner buying guide includes pros/features, cons and costs. It follows the format we’ve used in central air conditioner reviews for all leading brands.

The goal is to make it easy for you to research and compare brands. These compare to the cheapest units from major brands like Heil, Rheem, Carrier too.

Ameristar AC Top Features – Pros

Here are the advantages of considering Ameristar air conditioners.

1). Affordability is the main plus these units offer. They are essentially the same as their Trane and American Standard counterparts, but offered at a lower price with a shorter warranty.

2). The Ameristar M4AC6 air conditioner runs at just 67 decibels. That makes it one of the quietest single-stage central ACs available. It’s an ideal choice if the unit will be installed near a deck or patio.

3). 7 sizes of each model are produced: 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 and 5.0 tons. Each ton equals 12,000 BTUs, so the range is 18,000 to 60,000 BTUs. This many sizes means you’ll have a good fit for your home – an AC that isn’t too small and can’t keep up or too large and wasting energy.

4). Compact design. These aren’t as small as genuine “compact” ACs, but their cabinets are smaller than most standard air conditioners. This makes them popular for small backyards where there is little space to spare.

5). 10-year warranties. Consider the cheapest Lennox/Ducane warranties are 5 years. To get the 10-year warranty, you must register your product within 60 days. If you fail to, it becomes a 5-year warranty. Shortening the warranty is illegal in some states, but it makes sense to register your product regardless. Registration will make filing a claim and having it paid much easier.

Ameristar AC Cons

Here’s the downside of these units.

1). Limited efficiency: Models are 13, 14 and 16 SEER. Only the 16 SEER model is suitable for regions with warm summers. The others are OK for cool climates and part-time locations like a guest apartment or cottage.

2). All single-stage: Single-stage models are fine when low cost is more important than indoor climate control. They create slight temperature swings, since they tend to cool a little bit past the thermostat set point. The other issue is that they don’t remove as much humidity as two-stage and variable-capacity central ACs.

3). The 13 and 14 SEER units are loud. 76 decibels each louder than the average of about 73 decibels for entry-level air conditioners.

Model Analysis and Recommendations

This table is brief, since there are only 3 models. It shows the models and their basic features.


1). The Ameristar M4AC3 is a 13 SEER, single-stage air conditioner. It is sold only in northern climates – by law, ACs sold in southern regions must be at least 14 SEER.

Recommendation: In our opinion, the only suitable application for a 13 SEER air conditioner is in a part-time location where it won’t get much use. They use too much energy – with higher utility costs – for full-time use.

2). The Ameristar M4AC4 is a 14 SEER, this unit is only slightly more efficient. It is popular in part-time locations, but quite a few are sold for full-time use in cool climates where the AC isn’t needed much.

Recommendation: It’s a good fit in northern states when saving money on the equipment is more important than cutting utility costs.

3). The Ameristar M4AC6, at 16 SEER, this is the most efficient unit. But it is still single-stage, so doesn’t optimize indoor comfort.

Recommendation: This unit is suitable for cool to moderate climates and part-time use in warm climates. If your summers are hot, we recommend paying more for a more efficient AC from American Standard or Trane. The higher cost will be paid back in 3-10 years through lower energy bills.

Ameristar AC Prices

As noted, these units are all offered in 7 capacities from 1.5 to 5.0 cooling tons.

This table has two columns:

  • The System Only column is the cost of the AC, also called a condensing unit.
  • The System Installed price is the cost of the AC, the coil and all installation supplies.

As you compare Ameristar AC prices to other brands you are considering, you will see that this is a low-cost brand.

Ameristar AC Prices by Size

This is another way to sort Ameristar air conditioners.

The price ranges cover the three models, 13/14/16 SEER at each size.  

AC Unit SizeHome sizeEquipment costInstalled Cost

2.0 ton1001-1300 sf$1075 - $1,715$1,995 - $3,750
2.5 ton1301-1600 sf$1,265 - $1,900$2,125 - $3,985
3.0 ton1601-1900 sf$1,445 - $2,280$2,390 - $4,175
3.5 ton1901-2200 sf$1,665 - $2,400$2,600 - $4,455
4.0 ton2201-2600 sf$1,750 - $2,595$2,815 - $4,575
5.0 ton2601-3200 sf$1,885 - $2,750$2,950 - $4,700

* The “Home Size” column is a very rough estimate. The warmer your climate is, the bigger the AC must be relative to house size. Have a load test done to get your air conditioner properly sized.

To price an Ameristar for your home, it will be helpful to know the capacity of the current AC.

If you don’t know its size, check the metal tag with the model number. Look within the model number for any of these two digits which should indicate its capacity:

Model NumberCapacity  
181.5 tons
242.0 tons
302.5 tons
363.0 tons
423.5 tons
484.0 tons
605.0 tons

If your project is in new construction or you cannot determine the size of the old unit, then the HVAC technician should do a load test such as a Manual J to accurately size your AC.

Our Air Conditioner Buying Guide gives much more detail about sizing an AC and how important it is. It is the most comprehensive central air conditioner buying guide available.

Pro Note: If you have upgraded your home’s energy efficiency with added insulation, better windows and doors and other upgrades, your new AC should be smaller than the one it replaces.

How to Get the Best Estimates

As you know, you have to shop around. It can take a couple weeks to make a list of AC contractors, call them, wait for a return call, set up an appointment, etc.

A quick, easy way to expedite the process is to use the toll-free number or convenient Free Local Quotes form on this page. It reduces the time dramatically.
