Heil Air Conditioner Reviews and Prices (Updated in 2025)

Heil makes 13 central air conditioner models in two series that it calls the premium Ion Series and the value Performance Series. Just note that some of the Performance Series are more efficient than the least-efficient Ion Series. 

Heil’s is one of the largest lineups of any brand and gives you more options to tailor a system to your home’s AC needs.

Who is Heil?

Heil is a brand manufactured by International Comfort Products, or ICP. ICP is owned by Carrier. Heil ACs are similar in build and the parts used, but are not identical to Carrier (as Bryant is).

There’s more: ICP manufactures Day & Night, Tempstar and several other brands of HVAC equipment that are identical to Heil. Here at Pick HVAC, we think it is helpful to you to know “who’s who” as you compare Heil AC brands and prices to others you are considering. 

A fully installed central air conditioner might well be the single most expensive system in your home. You are wise to spend time researching products before you spend even one dollar of your hard-earned money. Heil makes two tiers of ACs, as noted. The Ion Series are some of the most efficient and dependable AC units on the market. The Performance Series, at lower costs and with less efficiency, are value-priced. Either way, you get a lot of bang for your buck.

How Heil AC Compares with Other Brands

When comparing Heil air conditioners to other brands in the market, several factors come into play, including price point, efficiency ratings, warranty coverage, and overall reliability. Here’s a detailed comparison of how Heil stands against its competitors:

Price and Value Proposition

Heil positions itself as a mid-tier brand, offering more affordable options compared to premium brands like Carrier and Lennox. While Heil units typically cost 10-15% less than top-tier brands, they still maintain respectable quality standards. For budget-conscious homeowners seeking a balance between cost and performance, Heil presents a compelling value proposition.

Efficiency Ratings

Heil’s top models achieve SEER ratings up to 19, which is competitive but slightly lower than premium brands that offer units with SEER ratings of 20-26. However, for most homeowners, Heil’s efficiency ratings are more than adequate for energy-saving performance. Their mid-range models, with SEER ratings between 14-16, compete well with similarly priced units from Goodman and York.

Warranty Coverage

One area where Heil stands out is warranty coverage. Their No Hassle Replacement limited warranty on premium models offers whole-unit replacement within a specified period (up to 10 years on top models), which exceeds many competitors’ warranties. This comprehensive coverage demonstrates Heil’s confidence in their products and provides significant value to homeowners.

Build Quality and Reliability

Being manufactured by International Comfort Products (ICP), a subsidiary of Carrier, Heil benefits from proven manufacturing processes and quality control standards. While they may not use the same premium components as Carrier’s top-tier lines, Heil units demonstrate reliable performance comparable to brands like Armstrong and Rheem.

Brand Recognition and Market Position

Although Heil may not enjoy the same brand recognition as Trane or Carrier, they have established a solid reputation in the HVAC industry. Their focus on providing reliable, cost-effective solutions has earned them a loyal customer base, particularly among homeowners seeking quality air conditioning without premium pricing.
