AirQuest Furnace Reviews: Is This a Brand to Avoid or Embrace?

Today, I want to introduce you to a brand that’s been on my radar: AirQuest. They’ve been causing a bit of a buzz in the HVAC world, so I thought it was time we dived into an in-depth review of AirQuest furnaces.

Established over two decades ago, AirQuest has steadily risen through the ranks to become a go-to choice for many homeowners. Their commitment to quality, innovation, and customer satisfaction has made them a key player in the HVAC industry. But did you know AirQuest is not a standalone entity? They operate under the vast umbrella of their parent company, International Comfort Products (ICP).

International Comfort Products (ICP) is known in the heating and cooling industry for manufacturing HVAC equipment under multiple brand names. Among the prominent ones are Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite, and AirQuest. Each brand has its distinct features and market presence but shares the commitment to quality and innovation fostered by ICP.

When it comes to home heating solutions, the features and benefits of the chosen product play a pivotal role in ensuring comfort, efficiency, and longevity. AirQuest, a notable name in the HVAC industry, offers furnaces that are packed with advanced functionalities designed to elevate the homeowner’s experience.

In this section, we delve into the standout features and benefits of AirQuest furnaces, highlighting what truly sets them apart in the market.

Efficiency and Performance

From my research and personal experience, AirQuest furnaces pack a punch in terms of efficiency. Most of their models are ENERGY STAR® qualified, which means you’re not only keeping warm but doing so in an eco-friendly way. Their variable-speed blowers ensure the right amount of heat disperses evenly throughout your home, optimizing comfort.

Design and Build Quality

In terms of design, these furnaces are compact, making them suitable for homes with space constraints. The build quality is commendable – made with durable materials meant to last, and trust me, they do.


The warranties offered by AirQuest furnaces, including the 10-Year No Hassle Replacement™ and Lifetime Heat Exchanger Limited Warranty, further bolster trust in the brand.

Drawbacks of AirQuest Furnaces

While AirQuest furnaces come with a host of commendable features, they are not without their drawbacks. Here’s a closer look:

  1. Limited Regional Availability: Some models, particularly those with ultra-low NOx emissions, are designed specifically for certain regions like parts of California. This can limit the options for homeowners residing outside these zones.
  2. Initial Cost: High-efficiency furnaces, like the ones AirQuest offers, can come with a relatively steep initial price tag. Although they promise savings in the long run due to reduced energy consumption, the upfront investment might be a deterrent for some.
  3. Maintenance Needs: With advanced features and integrated technologies, regular professional maintenance is essential to ensure peak performance. Homeowners might find these maintenance requirements more demanding than simpler furnace models.
  4. Complexity for DIY Enthusiasts: The inclusion of sophisticated features, like the Wi-Fi® enabled Ion™ System Control, can pose challenges for DIY enthusiasts. Troubleshooting and repairs may often require expert intervention.
  5. Compatibility Issues: While the furnaces are designed to be compatible with various thermostats and accessories, homeowners might face compatibility challenges if they are not using recommended or native brands.
  6. Size and Installation Space: Some users have noted that certain AirQuest models are bulkier, requiring more installation space. This can be a limitation for homes with constrained utility areas.
