I’ve worked with Heil Air Conditioners for years, and I know they balance efficiency, performance, and cost well.
Here’s a summary of what to expect from Heil:
Heil air conditioners – Quick guide!
Heil HVA9
The HVA9 is part of the top-tier QuietComfort Deluxe series and offers exceptional performance. It has advanced features (including WiFi control/monitoring), high energy efficiency (up to 19 SEER), and provides precise temperature and humidity control. Plus, it's ultra-quiet.
It is relatively expensive, around $6500, but offers more comfort and user-friendly features than other Heil models. It’s my top Heil AC and offers long-term value.
Heil N4A7
The N4A7 is part of Heil’s QuietComfort series and balances efficiency, performance, and features. It runs whisper quiet, has two-stage cooling for better temperature control, and can integrate with smart thermostats.
Priced around $2800, the N4A7 offers excellent value for money and is ideal in medium-sized homes.
N4A4**C
The N4A4**C is very affordable, but the basic features and lower efficiency (13 SEER) mean it offers less long-term value. It has limited coverage and can’t cope with high cooling demands, so I recommend spending slightly more on the higher-performing and Energy Star-rated Heil NH4A4 instead.
Heil is not the biggest name in the AC industry, but they are one of the trusted mid-range brands HVAC contractors recommend.
Their central air conditioner units focus on performance, not flair, and are known for being reliable and affordable.
In this guide, I'll explain everything you need to know about Heil AC units, explore the strengths and weaknesses of the brand, and who they are best for - so you can decide if they are right for you.
My review of Heil air conditioners
Pros and cons of buying a Heil AC
The good
The bad
Important Note:
I don't recommend Heil units for high traffic or high wind areas, as they can get damaged easier and the warranty doesn’t cover that kind of wear and tear.
Heil units work best in areas that are well protected from the elements, traffic, and even pets.
I have seen these wire protected condensers get the coil fins bent and then you have to “straighten” them with a coil comb. It won’t look good and your efficiency will start to go down.
Heil air conditioner prices – How much do they cost?
A Heil air conditioner typically costs $2000-$6000, but the exact price will vary depending on the model, size, features, and capacity.
Low-end models (the Performance Series) cost around $2000-$2500, while premium models (QuietComfort Deluxe) can cost over $5500.
Heil air conditioners are priced comparably to other mid-tier brands, like Goodman and York, and slightly higher than entry-level brands like Keeprite or Comfortmaker.
Installation costs will typically be $1500-$5000, depending on the AC size and complexity of the work, so you should expect to pay $3500-$8000 to have a new Heil air conditioner installed.
Pricing by model
Heil offers a range of products to suit different needs and budgets.
While the low upfront cost of their entry-level air conditioner systems can be tempting, the best value Heil units are their premium models, the QuietComfort Deluxe Series.
These have a higher upfront cost, but their energy efficiency and durability make them the best long-term investment.
Here’s a quick breakdown of what to expect for your money:
Category | Price Range (installed) | Expected Features | Series |
|---|---|---|---|
Low-end | $3500 - $5000 | Performance Series | |
Mid-range | $5000 - $7000 | QuietComfort Series | |
High-end | $7500 - $10,000 | QuietComfort Deluxe Series |

Cost variation across US states
Heil air conditioners, under the banner of Tempstar or UTC, are sold across the country from licensed dealerships. The cost can vary depending on:
Heil air conditioners tend to be cheapest in the Southern and Midwestern states, like Texas, Florida, Ohio, and Indiana.
These regions have lower labor costs and more HVAC contractors to increase competition and drive down costs.
They're also closer to the distribution centers for Heil, so the transport and shipping costs are lower.
Heil air conditioner systems are typically more expensive in the Northeast and on the West Coast, where the cost of living is higher.
I recommend getting several quotes from local dealers/HVAC contractors to guarantee a competitive price.

Exclusive features from Heil
ObserverⓇ communicating wall control
Advanced Heil air conditioner units have an advanced control system that allows for precise monitoring and adjustment of the HVAC system, allowing you to maximize energy efficiency and make your home more comfortable.
It’s great for homeowners who need precise cooling.
SmartSense™ technology

Heil’s SmartSense technology allows the air conditioner to adapt to changing conditions, detecting occupancy in the room or a temperature change to maintain a consistent temperature and maximize energy efficiency.
This feature is useful for homeowners living in unpredictable environments.
Ion™ system control
Premium Heil air conditioners feature an Ion system that helps with humidity control and air purification.
It's useful for homeowners who want to control the temperature and quality of their air.
Copeland scroll compressors
Heil air conditioners use single-stage, multi-stage, or variable-speed compressors.
The compressor technology varies between models, but all Heil AC units feature Copeland Scroll compressors.
These are known to be reliable, efficient, and quiet - and should give you confidence that Heil air conditioner systems will perform well.
Corrosion-resistant components
Heil uses corrosion-resistant components, such as aluminum coils and galvanized steel cabinets, in its AC units.
Aluminum isn't as strong as copper coils, but it does help keep the cost of Heil units down, which is something my customers always appreciate.
What I don’t like about the condenser design for Heil Units is that the coils are protected by a wire mesh instead of metal panels, which is why I don't recommend them for high traffic areas.
R-454B refrigerant
While not exclusive to Heil, I have to mention that I love that Heil is already transitioning their air conditioners to R-454B Refrigerant.
R-454B has a Global Warming Potential (GWP) of 466 and of course is non-ozone depleting. It's also non-toxic unless it starts to degrade.
QuietComfort technology
Heil uses QuietComfort technology to minimize the noise output without impacting performance.
Every Heil AC unit features swept-wing fan blades and compressor sound jackets that keep the decibel level below 75 - making them ideal for noise-sensitive homes.
Heil air conditioner's warranty analysis
Heil offers a competitive warranty on each AC unit. It varies depending on the particular model, but typically, Heil provides:
The AC unit warranty is above the industry standard (2-5 years) and on par with most mid-range brands.
Just note that some of the budget-friendly models do have slightly less coverage.
The warranty is fair and hassle-free, with a straightforward process for making a claim.
The Heil AC unit must also be installed properly by a licensed contractor to be valid and must undergo annual maintenance to remain valid.
Generally, Heil’s warranty protection is good and what I would expect from a brand at this price point, helping to protect your investment.

Heil HVA9
Main features:
The Heil HVA9 unit is part of the QuietComfort Deluxe Series and offers premium performance, high efficiency, and advanced features.
It automatically adapts to the conditions using a variable speed compressor system, produces low noise levels, and incorporates summer humidity control.
It’s also WiFi-enabled for remote access and control.
The Heil HVA9 is a premium model that is not budget-friendly. However, it is a real asset in larger homes with demanding needs and offers exceptional long-term value.
Heil HCA7
Main features:
The Heil HCA7 AC unit is part of the mid-tier QuietComfort Series and balances efficiency with affordability.
It offers reliable cooling in mid-to-large homes and produces low sound levels. Plus, it features WiFi capability for remote access and integration into smart thermostats.
This two-stage Heil unit offers humidity and temperature control in one and runs efficiently.
It’s not quite as impressive as the HVA9, but it’s more affordable and best for mid-sized homes that need reliable cooling.
Heil HSA5
Main features:
The Heil HSA5 is an entry-level Heil unit that provides basic temperature control for smaller homes or condos.
Despite the low cost, these Heil ACs still offer reliable cooling and run quietly (under 75 decibels).
The SEER rating is lower than other Heil units, but the ACs still run efficiently. Plus, you can upgrade this model with the Ion communicating system for remote access.
The HSA5 offers good value for small homeowners on a limited budget.
However, I recommend checking out the Heil HSA6 instead, which offers improved performance at a similar price point.
Heil HSA6
Main features:
The Heil HSA6 unit is an upgraded version of the HS5 - offering newer features, higher SEER ratings, and quieter operation.
This Performance Series central air conditioner has two-stage cooling for better temperature control and can cover a medium-sized home.
I recommend the Heil HSA6 for homeowners looking to add more efficiency and features on a budget.
Heil N4A4**C
Main features:
This Heil AC unit is for homeowners on the tightest budgets. It offers limited coverage but can be a real asset for smaller homes or apartments during summer.
The single-stage compressor system works reliably, and the corrosion-resistant cabinet can handle harsh weather or heavy wear and tear.
The Heil N4A4**C is best for homeowners in mild climates looking to upgrade from an old, outdated AC system.
Heil NH4A4
Main features:
The Heil NH4A4 is a slightly upgraded version of the N4A4**C with newer components that improve the overall efficiency.
It can still only cover a small home or apartment, but the lower energy costs will save you money in the long run.
It’s one of the most efficient central ACs I’ve seen at this price point.
The Heil NH4A4 is best for homeowners on small budgets who want reliable and cost-effective cooling. I recommend this budget-friendly model over the N4A4**C.
Heil N4A7
Main features:
The Heil N4A7 is part of the QuietComfort series and offers improved efficiency and a lower operational sound level.
The two-stage cooling is more effective than the Performance Series single-stage compressor units, and this AC works reliably in hotter temperatures.
The Heil N4A7 balances price, durability, efficiency, and price well. It’s best for homeowners with fairly basic temperature control needs who want a long-term (10 years +) solution.
Heil N4A6
Main features:
The Heil N4A6 is a slightly older and less efficient version of the N4A7. It only has a single-stage compression unit but can cover small-to-medium-sized spaces well.
It's also easy to maintain, runs quietly, and is durable enough to last 10-15 years. Like the N4A7, it has fewer additional features or smart integrations but is cost-effective.
The Heil N4A6 is a good option for homeowners on a budget looking to cool noise-sensitive homes reliably.
Heil NXA6
Main features:
The Heil NXA6 is part of the entry-level Heil Performance Series but is one of the highest-performing in the range.
It features a reliable single-stage compressor that works in high temperatures, an efficient 16 SEER rating, and is durable enough to withstand bad weather and debris.
The NXA6 offers affordable, long-lasting performance with low running costs.
In medium-sized homes, it offers great value and is perfect for homeowners upgrading old systems.
Heil installation explained for homeowners
Your Heil AC must be installed by a qualified professional to guarantee it works effectively and efficiently.
It typically costs $1500-$5000, and most dealers combine the installation cost with the unit price.
The installation costs can vary depending on:
How to find a reliable HVAC professional
Heil units are simpler than other brands, so you don't need a specialist HVAC contractor.
However, you should still look for an HVAC professional with at least 5 years of experience.
I recommend searching Heil’s database of Elite Dealers to find a suitable HVAC professional.
These dealers have specific experience with Heil and should do it correctly.
You can also search for licensed HVAC contractors on national directors, like the Air Conditioning Contractors of America website, or ask friends and family for recommendations.
Always check reviews and licenses and see examples of their work before you hire them.

Heil AC installation tips
The Heil brand at a glance
Heil is a well-established brand that started in the 1960s.
For over 60 years they have produced reliable HVAC systems for residential and light commercial use and have developed a reputation as a solid - if less advanced - brand.
The brand produces air conditioning systems, furnaces, heat pumps, and air handlers - and their focus is on performance rather than features.
Heil is owned by International Comfort Products Corporation, a United Technologies Corporation (UTC) subsidiary that also owns heating and cooling brands like Tempstar.
Their HVAC systems have similarities with other HVAC brands in this price range - partly because the same parent company owns several competitor brands.
Heil makes dependable equipment backed by good warranties, and they are a trusted mid-tier option for residential HVAC equipment.
Homeowner & buyer reviews
Heil is a respected mid-range HVAC brand, and users appreciate the balance of affordability and quality.
Feedback from homeowners and HVAC contractors shows that they are reliable and should last well if properly maintained.
Heil air conditioner reviews also mention how similar Heil is to other mid-range brands - particularly companies owned by the same parent company (UTC).
I would like to reinforce that correct installation matters as much as the air conditioner you choose, and it will prevent common problems with Heil air conditioners from occurring.
“Been installing ICP (Heil/Tempstar) equipment for about 20 years. As good as any, in my opinion. Just as with all brands, go with their premier line”

“I have 2 Heil units at my home , I am almost embarrassed to say how old they are (29 years) and have never had an issue with either 1”
- From Heil air conditioner reviews on Reddit
“I personally prefer Heil over York anyday. Have not cared for the Yorks I have worked on ( never installed any ). I do install 'Tempstar' which is the twin brother of the Heil and I will stand by it.”
- From Heil air conditioner reviews on HVAC-Talk Forum
“Everyone has their own opinion of equipment. Heil is fine, just don't buy their low end line…..Key is finding a dealer you feel will do the job right and put in the what he has to offer. A cheap product will do well if installed properly, the best product will be a headache if hacked in”

How do Heil air conditioners compare to top competitors?
Heil vs Trane
Trane is a premium air conditioner brand, and its models have advanced features and innovative technologies that allow their ACs to cool over a large area.
Trane air conditioners maximize home comfort with an impressive range of user-friendly air conditioners. However, they are expensive.
On the other hand, Heil is a more affordable brand that balances quality and price.
Their air conditioner models are more limited in comparison but are still reliable - with high-quality components.
If you have a flexible budget, want premium cooling, and want the latest AC technology, I recommend Trane.
However, if you have a tighter budget and less demanding climate control needs - Heil offers better value.
Related article: A comprehensive analysis of Trane AC brand
Heil vs American Standard
American Standard is one of the most prominent air conditioner and HVAC brands, with a wide selection of AC systems.
Their premium models have high energy efficiency ratings and smart features (such as adaptive cooling and remote diagnostics), and even their entry-level models are impressive.
The downside is that they cost more than other mid-range HVAC brands.
Heil air conditioner models are more limited, with fewer bells and whistles and more focus on reliable performance.
Heil can’t compete with the top-end American Standard air conditioner models but offers a cost-effective alternative (up to 40% cheaper) for basic cooling needs.
If you want advanced features and have diverse climate control needs, American Standard is a great option.
If you only need to cool a small-to-medium-sized home - I recommend Heil as a budget-friendly alternative.
Heil vs York
York offers far more variety than Heil, with entry-level and premium air conditioners to match different budgets.
York low-end models are priced comparably with Heil air conditioner systems. Still, other product tiers (LX Series, Affinity Series, etc.) cost noticeably more.
Heil’s products generally have fewer features than York air conditioner systems.
However, Heil’s mid-range and premium units offer similar performance at a lower price point.
If you have specific cooling needs or want to look at a broader spectrum of air conditioners (some with advanced features), York is the better choice.
If you want a reliable, cost-effective, and value-orientated air conditioner, I recommend Heil.

FAQs
Is Heil cheaper than Carrier?
Yes, Heil air conditioners are generally cheaper than Carrier units. Heil is a mid-range brand, while Carrier is a premium air conditioner brand that offers more advanced and efficient units.
Where is the model number on a Heil furnace?
The model number on a Heil furnace can be found on the rating plate or sticker on the exterior casing or the interior panel of the unit.
How do I know what size my Heil air conditioner is?
The Heil air conditioner size (ton rating) is typically listed on the outdoor unit’s rating plate or in the owner’s manual. You can then convert this to BTU.
How often should I service my Heil air conditioner?
You should have your Heil air conditioner professionally serviced, inspected, and cleaned at least once a year. I also recommend performing routine cleaning and maintenance yourself every 3-4 months.
Summary | Is a Heil AC right for you?
[usr 4.0]

On the surface, Heil air conditioner systems don’t jump out as the best or most high-performing - but on closer inspection, you can see the quality, efficiency, and durability.
Heil AC units don’t offer the advanced features of premium brands like Carrier or Trane but provide reliable cooling for homeowners on a budget.
They work best in mid-sized homes in regions with temperate climates, and I recommend investing in a higher-tier Heil system (from the QuietComfort or QuietComfort Deluxe Series) as they offer the best value.
