Daikin Gas Furnace Reviews | Consumer RatingsDaikin Gas Furnace Reviews | Consumer Ratings. Daikin offers gas furnaces for residential application in AFUE ratings from 80% to 98%. Their minimum efficiency gas furnace is single-stage operation while the Daikin top-tier gas furnace has modulating operation. The economy model is offered for those on a budget and those who really do not care about their utility bill. The top-tier Daikin gas furnace, while being costly for the upfront purchase, saves in the long run. The top-tier Daikin gas furnace is economical to operate because of its modulating operation. 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.

The big difference between the lower-tier units and higher-tier units are the heat exchangers. To get 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:

  • Convenient left or right connection for gas and electrical connections. This makes installation easier.
  • Silicon Nitride igniter in select Daikin gas furnaces
  • Variable-speed induced draft blower in select units
  • Diagnostic control board with constant memory fault code history. This feature helps with gas furnace troubleshooting in the event of a problem.
  • Enhanced dehumidification modes available. This feature helps in the summer with a properly matched system and is available only in select units.
  • Modulating gas valve for higher efficiency in select Daikin modulating gas furnaces.
  • Stainless-steel primary and secondary heat exchanger in select units. This is a necessity as combustion gases are very corrosive.
  • Select units Energy Star rated.
  • 12-Year Unit Replacement Limited Warranty and 12-Year Parts Limited Warranty in select units.

Daikin Gas Furnace Components Overview

Variable Speed Blower and Diagnostic Control Board

Pro

it is 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. This 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. 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 technicians job a little easier by showing the fault codes. This, on most diagnostic control boards, generates a flash code for furnace faults. Naturally, it makes the technicians job easier because he has a history of faults to look at on the control board.

Con

If something goes wrong special diagnostic tools are needed to troubleshoot the problem. If one of the electronic components for the blower go bad, it can be an expensive part if its out of warranty. If its in warranty you will likely have to pay for labor. 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

Pro

All of Daikins high efficiency gas furnaces have stainless steel heat exchangers. This is good for high efficiency furnaces because the condense a lot of moisture. This moisture is corrosive and stainless steel holds up good 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 it 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 the premium models. Additionally, its a very good idea to check the duct work for sizing requirements.

Cons

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. 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 One+ Smart Thermostat for Your New Gas Furnace

Daikin One+ is compatible with the following Daikin Gas Furnaces:

  • DM97MC
  • DC97MC
  • DC96VC
  • DM96VC
  • DM80VC
  • DC80VC

What is Daikin One+ and how does it work? The Daikin One+ is a smart thermostat that gives you WiFi capability through an app on your smart phone. This gives you remote monitoring and control abilities.

Leave the house for a long trip and forgot to change the thermostat setting? Change it to your desired setting anywhere you can connect to the internet. Coming home from a road trip and want to turn the HVAC system on so the house will be comfortable when you arrive?

Open the app a few hours out and set the HVAC system to your desired settings. It is also compatible with Amazon Alexa and the Google Assistant.

Furthermore, the comparison chart above represents a top-tier range model, a mid-tier range model, and an economy model. Daikin offers other models in various efficiency ranges for various prices. Because of regional considerations pricing varies and can never be quoted accurately. Other conditions for pricing include each individual job and contractor pricing.

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 began in 1924 manufacturing radiator tubes for aircraft. In 1938 they branched out and got into refrigeration providing refrigeration units for the Japanese Navy.  In the 50’s Daikin introduced their first air conditioners. As they grew so did Daikins innovation for various comfort and industrial cooling systems. In 2012, Daikin purchased Goodman Manufacturing out of Houston, Texas.
