Daikin Gas Furnace Reviews | Consumer RatingsDaikin Gas Furnace Reviews | Consumer Ratings. Daikin offers gas furnaces for residential applications in AFUE ratings from 80% to 98%. Their minimum efficiency gas furnace is a single-stage operation while the Daikin top-tier gas furnace has modulating operation. Economy models are available for those on a budget and those who do not care about their utility bills.

The top-tier Daikin gas furnace, while being costly for the upfront purchase, saves in the long run. Daikin’s top-tier gas furnace is economical to operate because of its modulating operation. It also offers a variable-speed blower for added efficiency. Furthermore, Daikin also has several mid-grade gas furnace units that offer a higher efficiency rating from the baseline 80 AFUE gas furnaces. Additionally, mid-grade units typically use two-stage operation.

Daikin Gas Furnace Reviews - The big difference between the lower-tier units and higher-tier units are the heat exchangers. For extra efficiency, the higher-grade units have secondary heat exchangers to absorb extra heat from the combustion gases before they are vented outside.  Other things add to the efficiency of gas furnaces such as ECM variable-speed blower motors and variable speed inducer motors. Finally, from the lowest grade model to the highest, Daikin offers reliability, durability, and quality. Various features of select Daikin gas furnaces include:

Energy Efficiency and Gas Furnace AFUE

Just because you spend extra money to buy a high AFUE gas furnace does not mean you will have true energy efficiency. There are many factors to getting true energy efficiency. Among these factors are:

  1. Proper installation of the gas furnace
  2. Ductwork Integrity
  3. Home Insulation including energy-efficient doors and windows
  4. Home humidity levels

Components Overview | Daikin Gas Furnace Reviews

Variable Speed Blower and Diagnostic Control Board | Daikin Gas Furnace Reviews


It is a soft-start and uses less electricity. It can be set to run at different speeds, depending on what else is going on. For example, for a modulating furnace, when the furnace is on low fire, the blower needs to be reduced. That makes it a perfect blower motor for demand-based furnaces such as modulating furnaces. Additionally, with a matched air conditioner and programmed properly, it can help dehumidify better in the summer. Finally, that keeps you cooler in the summer.

The diagnostic control board is helpful in many ways. It can help the homeowner figure out the problem. That can be good and bad, but it makes the technician’s job a little easier by showing the fault codes. That, on most diagnostic control boards, generates a flash code for furnace faults. Naturally, it makes the technician’s job easier because he has a history of faults to look at on the control board.


If something goes wrong special diagnostic tools are needed to troubleshoot the problem. Perhaps one of the electronic components for the blower goes bad. It can be an expensive part if the warranty is expired. If it’s in warranty, you will likely have to pay for labor. Furthermore, most HVAC warranties only cover the part and not labor.

I see no cons for the diagnostic control board aside from an expensive repair if it goes bad out of warranty.

Modulating Gas Valve and Stainless Steel Heat Exchangers | Daikin Gas Furnace Reviews


All of Daikin’s high-efficiency gas furnaces have stainless steel heat exchangers. Furthermore, this is good for high-efficiency furnaces because they condense a lot of moisture. Finally, this moisture is corrosive, and stainless steel holds up well against corrosive liquids.

The modulating gas valve is only in the premium Daikin furnaces. The Daikin modulating current model list is as follows:

  • DC96VC
  • DM96VC
  • DC97MC
  • DM97MC

Modulation of the burners offers a higher level of comfort along with efficiency. That along with the variable-speed fan and can keep up with demand provided it is sized, set up, and installed properly. It is very important to get skilled HVAC installers when you buy premium models. Additionally, it’s a very good idea to check the ductwork for sizing requirements.


The stainless steel heat exchangers are on the high-efficiency models. Despite the ruggedness and durability of stainless steel, I would want a long-term warranty on the heat exchanger. Furthermore, many HVAC manufacturers offer 20-year and even lifetime warranties on heat exchangers.

The modulating gas valve adds a level of complexity to troubleshooting problems if something goes wrong. Therefore, it is necessary to have skilled technicians troubleshoot the problems if they arise.

Daikin Warranty

We all want a quality product that is guaranteed or backed up with a good warranty.

Warranties | Standing Behind the Product | Daikin Gas Furnace Reviews

Always check with the manufacturer or dealer about warranty information. This information changes quite frequently. Additionally, always make sure to register the warranty within the deadline period after installation. Additionally, if an extended parts and labor warranty is available, I recommend purchasing this warranty, especially for higher-tier equipment.

Daikin offers some warranties that are above average and other warranties that are below the industry average. Always read the warranty and understand what you are buying before signing the bottom line. Most HVAC warranties are limited warranties for parts only.

That means you will have to pay for labor if something goes wrong. There are also some added hidden fees to be aware of with any HVAC brand warranty, not just Daikin. Lastly, we recommend purchasing a labor warranty if available, especially for the premium models.

Buyers Guide | Daikin Gas Furnace Reviews

Whenever you purchase new HVAC equipment, including a gas furnace, you will have to deal with a contractor. Dealing with a contractor can be a slippery slope. It doesn’t have to be if you know how to cover all your bases first. I likely won’t get any flack from other contractors for saying that because they know it’s the truth. Just go on YouTube, and you can find several videos from contractors talking about how they rescued a customer from a nefarious contractor.

Saying that not all contractors are bad. Many are a good, reliable tradesman who takes pride in their work. However, there are always the contractors who cut corners, and that, inevitably, ends up costing you the consumer. Therefore, we came up with an HVAC consumer buyers guide. Here are a few excerpts from our buyer’s guide:

  1. Always get at least three bids from contractors whom you have vetted. Learn how to vet a contractor in our free buyer’s guide.
  2. The primary decision factor when purchasing new HVAC equipment is not a brand.
  3. If the unit size changes then likely the ductwork size is going to change. That means new ductwork and added costs. Installing new ductwork is not cheap and is labor-intensive. Be prepared for this as it could add more to your installation costs.

Is Daikin a Good Furnace Brand? What is the Best Furnace Brand?

In my opinion, and the opinion of a friend who is a Daikin dealer, Daikin makes a good furnace. My friend tells me many of the complaints about Daikin come from people who chose a bad contractor. It is likely the furnace was installed incorrectly leading to problems and frustration. That leads to the next question. What is the best furnace brand? The best furnace brand is the furnace that is installed correctly. We cannot stress the importance of proper installation enough. See our buyer’s guide above for help.

Air Source Heat Pump Tips | Dual Fuel Heating

A dual fuel heat pump is a heat pump with a gas furnace for backup heating rather than electric heat strips.

Air source heat pumps have a backup heating source. In most installations, the backup heating source is electric heat strips. Electric heat strips are very cheap to install in most cases. However, while electricity is generally regarded as 100% efficient, producing it is more costly than other heating methods. For a more efficient heat pump, consider a dual fuel heat pump, or a heat pump with a gas furnace for the backup heat source. It will be more costly to install, but your monthly bills will be reduced.
