HEIL Air Conditioners Review 2025: A Legacy of Quality and Performance

Modernize Rating: 4/5

Average Cost: $4,000 - $8,000

We set out to review Heil air conditioning, exploring the products, prices, customer satisfaction, energy-efficiency, and more. We took a look at how Heil compares to others in the home comfort space.

Our Verdict: Heil is a solid option for those who want a high-quality air conditioner without the high price tag. Heil is good for those who are seeking excellent energy-efficiency but don’t want to deal with proprietary installation or lackluster warranties.

The Modernize Mission

Modernize maintains homeowner-first editorial integrity, meaning we accept no commissions and no partner links for this review. Our reviews are thoroughly fact-checked by our home improvement experts. Ratings are determined by a sophisticated algorithm to rate brands, including analyses of products, materials, quality, costs, sizes, durability, energy efficiency, and warranties.

Overview of Heil

In the early days, Heil was a company that created garbage trucks and sanitation solutions. Over time, the company branched out into other areas, including air conditioning. This caught the attention of Carrier, which bought Heil in 1999 and now maintains the companies as two separate brands.

Heil air conditioning services are backed by the quality standards of Carrier, making Heil a competitive option in the air conditioning market. Heil is not only reliable and affordable, but offers excellent warranty coverage. An investment in Heil is a strong investment in future savings with energy-efficient products, but it also helps ensure you’ll get serious longevity from the products you choose.

Why We Love Heil Air Conditioners

At Modernize, we’ve worked with a lot of homeowners over the years, and we know how important it is to find an air conditioner you can count on. That’s why we’re big fans of Heil. Backed by the advanced features of Carrier, Heil has been keeping homes comfortable for decades. We love that their systems come with competitive warranties, offer great energy efficiency, and still hit a budget-friendly or mid-range price point. No matter your home type, there’s likely a Heil system that fits. In our experience, they’re all built to deliver reliable comfort year after year.

Pros and Cons of Heil Air Conditioners

Do the pros outweigh the cons when choosing a Heil air conditioner? Here’s what to expect from this brand.

Heil AC Pros

  • Energy Efficiency: The SEER ratings for Heil are quite competitive, offering you more comfort and lower utility bills.
  • Smart Tech Features: Smart Sense technology allows you to control the thermostat from anywhere in the world.
  • Warranties: The warranties on Heil products are known to be among the most generous in the industry.

Heil AC Cons

  • Higher Initial Costs: Advanced features are great but often add to the price tag.
  • Dependence on Installers: Heil uses local installers, which might not be fully trained on what it takes to install a Heil product.
  • Limited Brand Recognition: Competitors like Trane or Rheem are better-known than Heil, which might make it tough to find some parts.

Heil AC Product Lines

Heil offers two main product lines for air conditioners: The Performance Series, which focuses on budget-friendly value, and the Ion Series, featuring premium ion air conditioning.

  • The Ion Series features Wi-Fi on all models, quiet operation, and a five or ten-year warranty.
  • The Performance Series currently consists of five models. They are budget-friendly, relatively quiet, and feature the 10-year warranty.

All Heil air conditioners have advanced SEER ratings, which can help reduce your monthly bills over time. Durable construction is a hallmark of Heil, so you can rest assured that all of the units they sell likely won’t need that good warranty, but it does make for a nice safety net.

Customer Reviews and Ratings

Heil air conditioners are known for being very durable and reliable. Many customers love the high-efficiency models and the 10-year limited warranty, but don’t like that you must register the unit in order to get the 10 years; otherwise, you only get five years of coverage.

Some users have found that the temperature fluctuates too much and the units are noisy, but many attribute that to an improper installation procedure, not to the Heil units themselves.

Here are some reviews from customers who have a Heil air conditioner:

“We had new Heil units installed in February when our heat went out. It was a new Heil gas furnace and air conditioner. We really only wanted a new furnace but after looking at everything and the age of our old air conditioner we didn’t want to have to worry about that going out soon also so we got the full package. We’ve had the guy come back once to check it out because we thought it was making a funny noise. Turns out everything was fine and it works great. Another bonus was our power bill and gas bill is a lot less with the new Heil system we got.”High Performance HVAC Review

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”Reddit Reviewer

“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.”Air Conditioner Lab Review

How Much Do Heil Air Conditioners Cost?

On average, Heil Performance Series air conditioners run between $3,000 and $7,000 including installation. The Ion Series can range from $5,000 to $9,000. The pricing depends heavily on where you live, the size of the unit, and additional features you might choose, such as Smart Technology. Here’s an idea of what to expect from costs based on SEER ratings and house size.

Factors Influencing Cost

Many factors can change your bottom line. These include:

  • Choice of Model: The Performance Series will be more affordable than the Ion Series; the costs vary between models of the same series.
  • Location: The local labor costs where you live contribute heavily to the final amount. As a general rule of thumb, places with high demand for installers – such as urban areas – will see a higher rate.
  • Higher SEER Rating: The higher the efficiency, the greater the up-front price; however, you will save more over time with a higher SEER rating.
  • Installation Complexity: The more difficult it is to access the areas necessary for installation, the more likely your contractor will charge more.
  • Necessary Upgrades: If you need upgraded ductwork or electrical work, there will be an additional charge for that.
  • Smart Features: Units equipped with Wi-Fi, sound dampening, and special coatings for weather resistance will all add to the price.

Heil Air Conditioners vs. Main Competitors

While Heil air conditioners might be more affordable than most of the offerings of their top AC brand competitors, don’t mistake that for meaning that Heil is a sub-par brand. On the contrary, the company offers warranties that are just as good as the other guys, models with whisper-quiet operation, and Smart Technology that ensures you can keep tabs on your unit no matter where you are. Here’s how Heil compares to a few major competitors:

Heil vs. Carrier

  • Cost Range: $3,000 to $15,000
  • Pros: Sister brand to Heil; great brand recognition; durable designs.
  • Cons: Warranty coverage might be lacking; higher price point; complex installations.
  • What Sets Heil Apart: Delivers similar quality and efficiency to Carrier but at a more approachable price point, making it a strong choice for homeowners seeking value without compromise.

Frequently Asked Questions About Heil Air Conditioners

Do you have more questions about Heil air conditioners? These answers might help.

What are the warranties like for Heil air conditioners?

Heil offers 5-year and 10-year limited warranties. To take advantage of those warranties, you must register your unit soon after installation. If you do not register the unit, your warranty drops from 10 years to 5 years.

Can I choose my own installer for Heil air conditioning units?

Yes, absolutely. Heil doesn’t require their own technicians to install, so you have ample room to get quotes from local installers and choose the one that’s right for you.

Where can I find discounts on Heil products?

Heil products are sold by local retailers and through online warehouses. Look for promotions not only from Heil, but from the place where you purchase the air conditioner. Seasonal sales are often excellent ways to save money.

Final Verdict: Should You Choose a Heil Air Conditioner?

If you are looking for an air conditioner that has the longevity and performance of high-end models without the equivalent price tag, Heil is the right brand for you. The lack of name recognition might be a turn-off at first, but keep in mind that a lesser-known company can provide just as much cooling power as the bigger names for much less expense.

Heil products are great for those who want to choose their own installer, who prefer to buy from where they please, and who want to have the energy-efficient, quiet, and reliable performance that is absolutely essential for a good AC unit.
