ComfortMaker Review Furnace

ComfortMaker is a residential HVAC brand manufactured by International Comfort Products (ICP), a subsidiary of Carrier Global. The brand positions in the middle of the market — typically priced below Carrier and Bryant, but carrying the same parent-company engineering and many of the same underlying platforms as sibling brands Heil, Tempstar, KeepRite, and Day & Night.

This review covers what ComfortMaker owners report on our platform, how the current 17-model lineup breaks down, how the warranty compares (including the meaningful variation across unit replacement coverage), and where ComfortMaker fits relative to its ICP family siblings.

The Bottom Line

ComfortMaker furnaces earn broadly positive owner feedback on our platform, with sentiment skewing positive and an average reported installed price roughly in line with other ICP-family brands. Reliability is the theme that comes up most often in owner reviews.

The review pool is smaller than for Carrier or Lennox, which means individual data points — positive and negative — carry more weight.

ComfortMaker is a good fit if you:

• Want a Carrier-engineered platform at a lower price point than Carrier or Bryant branded models
• Have access to a contractor who regularly installs ICP-family equipment
• Value unit replacement coverage on certain mid- and top-tier models (a benefit not all sibling brands include)
• Plan to stay long-term and want lifetime heat exchanger coverage

Consider other brands if you:

• Want a deeper pool of owner reviews for reassurance — Carrier, Lennox, and Trane all have substantially larger review volumes
• Want labour coverage built into the base warranty (some Lennox and Amana models include versions of this)

ComfortMaker vs. Heil vs. Tempstar vs. KeepRite

ComfortMaker, Heil, Tempstar, and KeepRite are all manufactured by International Comfort Products (ICP), a Carrier Global subsidiary. The four brands share the same underlying platforms on most models — often the identical chassis with different badging, sold through separate contractor networks.

The practical differences are distribution and naming. KeepRite is positioned primarily for the Canadian market with a shorter, region-focused lineup. ComfortMaker sits in a similar position with Canadian distribution. Heil and Tempstar have broader US distribution and larger review pools on our platform. Day & Night and Arcoaire round out the ICP family in specific regional markets.

Warranty terms are broadly aligned across the ICP family, though the specific unit replacement structure varies by model within each brand. If you're comparing quotes across ComfortMaker, Heil, Tempstar, and KeepRite for similar specs, you're pricing closely related equipment — the contractor's installation quality and service reputation matter more than the brand label.

ICP itself sits under the broader Carrier Global umbrella alongside Carrier, Bryant, and Payne, though the ICP family runs on a separate manufacturing platform and isn't a direct Carrier/Bryant equivalent.

Customer Reviews Summary

Across 12 reviews collected through our platform, ComfortMaker furnaces average about 4.4 out of 5 with an average reported installed price of around $5,900. Sentiment skews positive — roughly eight in ten owners rate their unit positively, with a smaller but real share of mixed or negative reports.

The most frequently cited positive is reliability (ten mentions), followed by runs great and energy efficient (seven mentions each). Quiet operation and great features appear less often than on some competing brands, which tracks with owner comments describing the furnaces as solid and effective but not standout on refinement.

On the negative side, a small number of owners flagged reliability issues or inadequate performance — in absolute numbers these are few, but worth noting given the smaller pool size.

One owner of a ComfortMaker two-stage model offered a balanced perspective:

Runs great, energy efficient, reliable, great features. Noisier than a mid-efficiency unit, but the DC fan motor is a plus.

The review pool is modest in size, which means a few stronger or weaker individual reports can meaningfully shift average impressions. One owner reported serious issues requiring substantial troubleshooting, which is the kind of experience that warrants acknowledgment alongside the generally positive sentiment.

Given the smaller data set, it's also worth cross-referencing ComfortMaker's sibling brands (Heil and Tempstar particularly) which run on the same manufacturing platform and have larger review pools — similar sentiment patterns on those pages provide broader validation.

Lineup & Pricing

Installed pricing varies significantly by tier, home size, regional labour rates, and installation complexity. The figures below are starting points based on owner-reported prices — always use your own quotes as the baseline.

Top-Tier (96.7–98% AFUE)

Installed price range: roughly $6,000 to $9,000+ depending on size, configuration, and installation complexity.

• G97CMN — ComfortMaker's flagship, 98% AFUE with a modulating burner and variable-speed ECM blower. The top comfort and efficiency option, and one of the few models in the lineup with 10-year unit replacement coverage.
• G97VTN and G97CTN — 97% AFUE two-stage options with variable-speed ECM blowers.
• G96CTN and G96VTN — 96.7% AFUE two-stage siblings, the G96CTN adding 10-year unit replacement coverage.

Mid-Range (95–97% AFUE, Single-Stage)

Installed price range: roughly $4,500 to $6,500.

• N96VSN and N96MSN — 97% AFUE single-stage options with variable-speed ECM blowers.
• G95CSU — 95% AFUE single-stage, notable for including 5-year unit replacement.
• N92MSN — 92% AFUE single-stage option. Note: 92% AFUE does not meet the 95% minimum for new gas furnace installations in most Canadian provinces.

US-Market Models (Sub-95% AFUE)

ComfortMaker offers a range of 80% AFUE gas furnaces (G80CTL, G80VTL, G80CSU, N80MSN, N80MSL, N80ESU, N80VSL) along with the 92% N92MSN. These don't meet the 95% AFUE minimum for new gas furnace installations in most Canadian provinces and are primarily available in the US market.

Warranty Analysis

The Warranty Terms

Every current ComfortMaker furnace shares the same core warranty foundation: 5 years base parts, 20 years base heat exchanger, and 10 years parts when registered within 90 days of installation. Labour coverage is not included on any model.

Where ComfortMaker's warranty differs from sibling brands is unit replacement coverage, which varies meaningfully by model. There are three tiers within the current lineup:

Models with 10-year unit replacement: G97CMN, G96CTN, and G80CTL. These top-tier models include a decade of unit replacement coverage if the heat exchanger fails within that window.

Models with 5-year unit replacement: G97VTN, G96VTN, G95CSU, G80VTL, and G80CSU. These mid-tier models include a shorter five-year window for unit replacement.

Models without unit replacement: G97CTN, N96VSN, N96MSN, N92MSN, N95MSU, N80MSN, N80MSL, N80ESU, and N80VSL. These models rely on heat exchanger replacement alone rather than full unit swap.

Extended heat exchanger coverage also varies slightly. Most models include lifetime extended heat exchanger coverage with registration, but several (N92MSN, N95MSU, and all N80 series) cap extended heat exchanger coverage at 20 years rather than lifetime. All other warranty terms remain identical.

Registration Is Required

To unlock the extended coverage (10 years parts, lifetime or 20 years heat exchanger, and the unit replacement provisions where applicable), the furnace must be registered within 90 days of installation. If that window is missed, coverage reverts to the base terms: 5 years parts and 20 years heat exchanger only.

Confirm with your installer that they've either registered the unit or provided you with the information to do it yourself.

Note for Quebec residents: Quebec consumer protection law prohibits conditioning warranty coverage on registration. You automatically receive the full extended warranty terms without needing to register — the registration deadline doesn't apply.

How It Compares

ComfortMaker's warranty is solid for its price tier. The unit replacement coverage on select models (10 years on the G97CMN, G96CTN, and G80CTL) is more generous than what Carrier and Bryant offer in equivalent product tiers — both Carrier-family brands generally don't include unit replacement.

Amana and Goodman still lead the industry with lifetime unit replacement on flagship models, plus 10-year parts and lifetime heat exchanger — the most generous structure at this price point. Lennox offers 10-year unit replacement on some top-tier models. Napoleon offers lifetime parts on select models with registration.

Where ComfortMaker stands out is the mix of unit replacement coverage on multiple tiers — rare for a brand at this price point. Where it falls short is the absence of labour coverage and the varied coverage levels across the lineup, which means the specific model quoted matters more than it does for brands with uniform warranties.

Notable Features

Variable-Speed ECM Blower (standard across all current models)

What it is: An ECM blower motor that ramps airflow up and down gradually to match heating demand, rather than snapping between fixed speeds.

The practical benefit: Quieter airflow, more even temperature distribution, and lower electricity use compared with older PSC blower motors. ComfortMaker includes this across the entire current lineup — including entry-level 80% AFUE single-stage units — which is a meaningful spec advantage over some value-tier brands that still use fixed-speed blowers at equivalent price points.

Unit Replacement Coverage (select models)

What it is: A warranty provision that replaces the entire furnace — not just the heat exchanger — if the heat exchanger fails within the coverage window. Available as 10 years on the G97CMN, G96CTN, and G80CTL, or 5 years on the G97VTN, G96VTN, G95CSU, G80VTL, and G80CSU.

The practical benefit: Meaningful peace of mind on a covered failure — the homeowner avoids the labour complication of installing a replacement heat exchanger into an otherwise-aging chassis, which on some older furnaces is uneconomic.

Worth knowing: Coverage requires registration within 90 days of installation, and applies only to the specific models listed above. Nine of the 17 current models don't include this provision, so the model quoted matters — it's worth confirming with the installer which tier your selection falls into.

ICP Family Platform

What it is: ComfortMaker shares its underlying manufacturing platform with Heil, Tempstar, KeepRite, Day & Night, and Arcoaire under International Comfort Products. Core components — heat exchangers, burners, control boards, blower assemblies — are common across sibling brands.

The practical benefit: Service parts are widely available through the broader ICP distribution network, not just ComfortMaker-branded contractors. Technicians familiar with any ICP-family brand can typically service a ComfortMaker furnace.

Worth knowing: The shared platform is a reason to look at sibling-brand owner reviews (particularly Heil and Tempstar, which have larger review volumes on our platform) when evaluating long-term reliability — the underlying equipment is closely related.

Add-Ons & IAQ Accessories

ComfortMaker offers a range of indoor air quality accessories that pair with the furnace, including media and electronic air cleaners, whole-home humidifiers, UV germicidal lamps, and HRV/ERV ventilators. These are typically sold and installed alongside the furnace through the same contractor rather than as DIY add-ons. None are essential, but a good installer will flag which ones make sense for your home.

About ComfortMaker

ComfortMaker is manufactured by International Comfort Products (ICP), headquartered in Lewisburg, Tennessee. ICP has operated as a residential HVAC manufacturer for decades and became part of Carrier Global through a series of corporate transitions. The ComfortMaker badge sits alongside Heil, Tempstar, KeepRite, Day & Night, and Arcoaire within the ICP family, with shared engineering and manufacturing across the group. Carrier Global — ICP's parent — also owns the Carrier, Bryant, and Payne brands, though those run on a separate manufacturing platform.

Frequently Asked Questions

Is ComfortMaker a good furnace brand?

Owner sentiment on our platform skews positive, with roughly eight in ten owners rating their unit positively and an average reported installed price of about $5,900. The specs are comparable to premium-branded competitors — variable-speed ECM blowers are standard, and top-tier modulating and two-stage options are available. The main caveats are a smaller review pool than larger brands and variation in unit replacement coverage across the lineup.

How long does a ComfortMaker furnace last?

Most gas furnaces in this tier are designed to last 15 to 20 years with regular annual maintenance. Longevity depends heavily on installation quality, maintenance, and whether the furnace was properly sized for the home. Registration within 90 days of installation is important to lock in the extended warranty coverage.

Is ComfortMaker the same as Heil or Tempstar?

ComfortMaker, Heil, Tempstar, KeepRite, Day & Night, and Arcoaire are all manufactured by International Comfort Products and share the same underlying platforms on most models. The practical differences are distribution (separate contractor networks) and modest pricing variation by region. The equipment itself is closely related — in many cases running on identical chassis.

How much does a ComfortMaker furnace cost installed?

The average reported installed price in our review pool is around $5,900, with individual reports ranging from the low $2,000s on entry-level installations to $10,000+ on high-end modulating installations with significant ductwork or venting work. Pricing varies significantly by model tier, home size, regional labour rates, and installation complexity.

Which ComfortMaker models include unit replacement coverage?

Three models include 10-year unit replacement: the G97CMN, G96CTN, and G80CTL. Five additional models include 5-year unit replacement: the G97VTN, G96VTN, G95CSU, G80VTL, and G80CSU. The remaining nine current models don't include this provision. Registration within 90 days of installation is required to activate the coverage.
