Heil Furnace Review

Heil is an American HVAC brand with roots going back to 1929. Since 1998 it has been part of International Comfort Products (ICP), which was acquired by United Technologies and is now owned by Carrier Global. Heil shares its manufacturing platform with Tempstar, Comfortmaker, KeepRite, Day & Night, and Arcoaire — all ICP-family brands built in the same facilities.

Within that cluster, Heil is typically positioned as one of the lower-priced options, with warranty terms that compete with more expensive tiers.

This review covers the current 2026 Heil furnace lineup, warranty structure, and how Heil fits within the broader ICP and Carrier Global portfolio. Owner review volume on our platform is limited for this brand, so the feedback section is short and anchored in the data we have rather than extrapolated.

The Bottom Line

Heil is a warranty-forward value brand under the Carrier Global umbrella. You get the same underlying ICP platform that powers Tempstar, Comfortmaker, KeepRite, and Day & Night, combined with the No Hassle Replacement Limited Warranty™ on premium models and a 90-day registration window that's more forgiving than most competitors' 60-day windows.

The trade-off is a smaller review pool on our platform — there's less direct owner data to draw on compared to higher-volume brands.

Heil is a good fit if you:

• Want a premium warranty structure — including unit replacement coverage — at a lower price point than Carrier or Bryant
• Have a local Heil dealer you trust (installer quality matters substantially at this tier)
• Are replacing an older furnace and value the extra flexibility of a 90-day registration window
• Are comfortable with a lesser-known brand name in exchange for stronger spec-to-price ratio

Consider other brands if you:

• Prefer to buy based on a large pool of independent owner reviews — Heil volume on our platform is limited
• Want lifetime heat exchanger coverage on every model (five Heil models cap heat exchanger coverage at 20 years)
• Value brand name recognition for home resale (Carrier or Trane carry more weight with some buyers)

Heil and the ICP Family: How the Sibling Brands Compare

Heil sits inside the International Comfort Products (ICP) cluster, which includes Tempstar, Comfortmaker, KeepRite, Day & Night, and Arcoaire. All of these brands are manufactured in the same facilities on the same underlying platform, with similar core specs and warranty structures. The differences between them are largely in branding, distribution channels, and minor trim-level variations.

Within that cluster, Heil and Tempstar are generally considered the most technically comparable — nearly identical lineups, similar warranty terms, and similar installed pricing. KeepRite is the Canadian-market-focused sibling with the same underlying engineering.

Day & Night and Arcoaire tend to be regionally distributed. All ICP brands sit one tier below Carrier and Bryant in the broader Carrier Global portfolio, which means you generally get similar engineering at a lower installed cost, but without the Carrier or Bryant brand premium.

If your dealer is quoting a Heil, it's worth asking whether they can also quote a Tempstar, Comfortmaker, or KeepRite on the same job. Pricing between the ICP siblings can vary by dealer, and the underlying product is largely the same.

What Heil Furnace Owners Are Saying

Heil has a smaller owner review pool on our platform than most major furnace brands — currently three reviews with an average rating of about 4.7 out of 5 and a 100% positive sentiment skew. The average reported installed price from those reviews is around $4,000. The three reviewers who did submit feedback flagged runs great, energy efficient, and great features as the attributes they appreciated.

With a review pool this small, we're careful not to extrapolate more than the data supports — three data points isn't enough to derive reliable patterns. If you're researching Heil, the more useful comparison anchors are the specs and warranty structure (covered below) and the sibling-brand reviews for Tempstar, Comfortmaker, and KeepRite, where we have substantially larger review pools that reflect the same underlying ICP platform.

Heil Furnace Lineup & Pricing

Heil's 2026 lineup covers four tiers. The Canadian-market models are 92% AFUE and higher; the 80% AFUE models are available in the US market only.

Top-Tier: Modulating (98% AFUE)

Installed pricing typically ranges from $6,500 to $9,000. The top-tier model pairs a modulating burner with a variable-speed ECM blower for the most refined comfort and efficiency in the lineup.

• G97CMN — Heil's flagship modulating furnace at 98% AFUE, ENERGY STAR® certified, with 10-year unit replacement coverage

Upper Mid-Range: Two-Stage 96.7–97% AFUE

Installed pricing typically ranges from $5,500 to $7,500. Two-stage models are the volume tier for Heil — meaningful comfort gains over single-stage without the modulating premium.

• G97CTN — 97% AFUE two-stage with variable-speed ECM, ENERGY STAR certified, 10-year unit replacement
• G97VTN and G96VTN — 97% and 96.7% AFUE two-stage, ENERGY STAR certified, 5-year unit replacement
• G96CTN — 96.7% AFUE two-stage, 10-year unit replacement (not ENERGY STAR certified)

Mid-Range: Single-Stage 95–97% AFUE

Installed pricing typically ranges from $4,500 to $6,000. Single-stage models still include the variable-speed ECM blower, which is unusual at this tier and supports quieter operation.

• N96VSN and N96MSN — 97% AFUE single-stage, ENERGY STAR certified; note: these models do NOT include unit replacement coverage
• G95CSU — 95% AFUE single-stage, ENERGY STAR certified, 5-year unit replacement
• N95MSU — 95% AFUE single-stage; 20-year heat exchanger coverage rather than lifetime, no unit replacement

Entry-Level: 92% AFUE

Installed pricing typically ranges from $3,500 to $5,000. At 92% AFUE this model meets Canadian minimum efficiency standards in provinces that require 92%+ but not those requiring 95%+ — verify local requirements before specifying.

• N92MSN — 92% AFUE single-stage, ENERGY STAR certified; 20-year heat exchanger rather than lifetime, no unit replacement coverage

Heil also offers several 80% AFUE models (G80CTL, G80VTL, G80CSU, N80MSN, N80MSL) for the US market. These don't meet the 95% AFUE minimum for new installations in most Canadian provinces.

Warranty Analysis

Heil's warranty is the brand's strongest competitive angle and the single biggest reason it earns its place on most shortlists. The core coverage across the current lineup is 5 years base parts, 20 years base heat exchanger, extending to 10 years parts and (on most models) a lifetime heat exchanger when registered within 90 days of installation.

On premium tiers, the No Hassle Replacement Limited Warranty™ provides full unit replacement if a covered major component fails during the coverage period.

Registration Window (Outside Quebec)

The 90-day registration window is more forgiving than the 60-day window used by Daikin, Goodman, Lennox, and most other major brands — a small but real practical advantage. Miss the deadline and parts coverage reverts to 5 years from the installation date. Confirm with your installer that registration has been completed, and look for a confirmation email directly from Heil.

Quebec residents are an exception: Under Quebec consumer protection law, Heil cannot condition warranty coverage on registration. Quebec homeowners automatically receive the full 10-year parts warranty without needing to register — Carrier Global's own warranty documentation confirms this applies across all ICP-family brands.

Where Models Differ

Warranty terms vary more across Heil's lineup than across sibling brands like Daikin or Goodman:

• Lifetime heat exchanger + 10-year unit replacement: G97CMN, G97CTN, G96CTN, G80CTL (the top-tier models)
• Lifetime heat exchanger + 5-year unit replacement: G97VTN, G96VTN, G95CSU, G80VTL, G80CSU
• Lifetime heat exchanger + no unit replacement: N96VSN, N96MSN (premium single-stage)
• 20-year heat exchanger + no unit replacement: N92MSN, N95MSU, N80MSN, N80MSL (entry-tier single-stage)

If unit replacement coverage matters to you, focus on the "G"-prefix models — the "N"-prefix single-stage models generally don't include it. And if you want lifetime heat exchanger coverage specifically, avoid the N-series entry tier models (N92MSN, N95MSU, N80MSN, N80MSL), which cap at 20 years.

How It Compares

Heil's registered warranty is genuinely competitive at its price point. The lifetime heat exchanger coverage on most models matches Carrier and Bryant (both more expensive brands) and effectively beats most budget-brand warranties. The 10-year extended parts term is industry-standard — two years behind Daikin's 12 but matching most competitors.

The 90-day registration window is a meaningful practical advantage over the 60-day windows used by Daikin, Goodman, Lennox, and Trane. Like most of its competitors, Heil does not include a labour warranty — labour coverage is entirely installer-dependent. Some Lennox Premier dealers in Canada offer bundled labour warranty programs that Heil's channel does not.

Notable Features

No Hassle Replacement Limited Warranty™

What it is: On premium Heil furnaces, if a major component (heat exchanger) fails during the coverage period, Heil will replace the entire furnace rather than just the failed component — at no equipment cost to the homeowner.

The practical benefit: A full unit replacement avoids the situation where you get a repaired older furnace with aging secondary components. For homeowners who plan to stay in their home long-term, this is a meaningful long-tail protection.

Worth knowing: The "No Hassle" label applies to premium models only — entry-level tier furnaces don't include it. The coverage period is tied to unit replacement terms (typically 10 years on top-tier models, 5 years on mid-tier). Labour for the replacement itself is not covered and depends on your installer's labour warranty policy.

Variable-Speed ECM Blower Across the Lineup

What it is: Every current Heil furnace — including entry-level single-stage models — ships with a variable-speed ECM blower rather than the single-speed PSC motors common at budget price points.

The practical benefit: The blower ramps airflow gradually rather than snapping between fixed speeds, which keeps sound levels lower and improves comfort. ECM motors also draw 60–80% less electricity than conventional blowers during continuous-fan operation.

Worth knowing: This is standard across all current ICP-family brands (Tempstar, Comfortmaker, KeepRite, Day & Night) — not a Heil-specific differentiator.

90-Day Registration Window

What it is: Heil gives homeowners (outside Quebec) 90 days after installation to register their product for full warranty coverage, rather than the 60-day window used by most competitors.

The practical benefit: A real buffer against the common scenario where an installer forgets to register, the paperwork gets misplaced, or the homeowner plans to register but simply forgets in the flurry of post-install adjustments.

Worth knowing: Even with the longer window, it's still worth confirming registration within the first week or two after installation — the 90 days is a grace period, not an excuse to delay.

Add-Ons & IAQ Accessories

Heil sells a line of indoor air quality accessories that pair with its furnaces — media air cleaners, whole-home humidifiers, UV germicidal lamps, and HRV/ERV units. These are functionally comparable to equivalent accessories from Honeywell, Aprilaire, and other aftermarket brands. There's no compelling reason to feel locked into Heil-branded IAQ equipment unless your installer has a specific preference.

About Heil

Heil was founded in 1929 by Julius Heil and became a significant HVAC manufacturer through the mid-20th century. The brand was acquired by Inter-City Products (later renamed International Comfort Products, or ICP) in 1988, and ICP was acquired by United Technologies in 1999. Carrier split off from United Technologies in 2020 to become Carrier Global, bringing Heil and the entire ICP portfolio with it. Heil furnaces are manufactured at shared facilities with its ICP sibling brands (Tempstar, Comfortmaker, KeepRite, Day & Night, and Arcoaire) and distributed through an independent dealer network across North America.

Frequently Asked Questions

Is Heil a good furnace brand?

Heil is a mid-tier furnace brand with strong warranty coverage for the price point, including lifetime heat exchanger coverage on most models and the No Hassle Replacement Limited Warranty™ on premium tiers. Our direct owner review pool for Heil is small (3 reviews as of April 2026), so we rely more heavily on spec comparison and sibling-brand feedback from Tempstar, Comfortmaker, and KeepRite, which share the same underlying ICP platform.

How long does a Heil furnace last?

A properly installed and maintained Heil furnace should reasonably last 15–20 years, in line with the industry average for modern high-efficiency gas furnaces. The lifetime heat exchanger warranty on most models (with timely registration or automatic in Quebec) and 10-year parts coverage provide meaningful protection through most of that expected lifespan.

Is Heil the same as Tempstar, Comfortmaker, or KeepRite?

Heil, Tempstar, Comfortmaker, KeepRite, Day & Night, and Arcoaire are all ICP-family brands manufactured in the same facilities on the same underlying platforms. Core specs and warranty structures are similar across the cluster, with differences mainly in branding, distribution channels, and minor trim-level variations. For most practical purposes, the underlying product is effectively equivalent.

How much does a Heil furnace cost installed?

Based on the limited review data on our platform, Heil furnace installations appear to average around $4,000 for mid-tier models, though the full range spans roughly $3,500 for entry-level single-stage installs up to $9,000+ for flagship modulating units. Final pricing depends on home size, ductwork condition, regional labour rates, and any required venting or electrical upgrades.

What's the difference between Heil's "G" and "N" model prefixes?

The "G" prefix generally indicates Heil's higher-tier models with more generous warranty terms — lifetime heat exchanger and either 10-year or 5-year unit replacement coverage. The "N" prefix typically marks entry and mid-range single-stage models, which in some cases have shorter heat exchanger warranty (20 years rather than lifetime) and no unit replacement coverage at all. If warranty coverage is a priority, the G-series is generally the better starting point.
