Carrier Versus Rheem Gas Furnaces. We compare the top-tier Rheem gas furnace to the top-tier Carrier gas furnace by comparing basic options and then describing these options for you. We receive tons of requests for these types of comparisons, and Rheem versus Carrier filtered to the top of the list for gas furnaces.

I always recommend when you replace and type of HVAC equipment, you get matching systems. For example, if your compressor goes bad and you need to replace the condenser, I recommend you also get the indoor units with the outdoor unit.

There are a few exceptions to this, and it depends on the age of the equipment and your budget. In the long run, getting a matching system will save you in energy cost as most manufacturers have equipment set up to give maximum efficiency for matched systems.

Carrier Versus Rheem Gas Furnaces | Brand Model Technical Review

Carrier Versus Rheem Gas FurnacesRheem has manufacturing facilities here in the USA while Carrier announced they are relocating their manufacturing facility from Indiana to Mexico in the near future. Both manufacturers have excellent dealer networks and training programs for their dealers.

That is important. It increases the possibility you will get a competent installation of your new system. Proper installation is essential to the efficiency and longevity of the system. Improperly installed systems will not be as efficient as the rating and will likely cause problems that will result in repair calls.

That is the primary reason why I recommend getting the best contractor over the brand.

In our side-by-side comparison matrix, we chose the most common features and compared them. Then we give basic descriptions and more detail below the matrix comparison. That helps you compare the features and develop questions and answers about what the best furnace is for you.

It cuts through the sales literature hype and helps you make a better decision as to which furnace to purchase. Your point of contact will be the salesman or dealer representative who wants you to sign a contract. Before signing any contract, you want to know what you are getting, and you want it spelled out in the contract.

Additional work outside of the installation, such as ductwork, running a new line set, running new wire, relocating the condenser, or anything discussed should be in the contract in writing. Additionally, the contractor should provide a load calculation upon signing the contract.

Features | Carrier Versus Rheem Gas Furnaces

Top Efficiency

Carrier does have Rheem beat in this category if only you want another one a half percent AFUE out of the furnace. Remember, the efficiency rating on the side of the furnace is only what that particular model got a top rating for when tested.

It does not mean you will get that efficiency after the furnace installation is complete. There are too many factors involved in the testing, and they are too complex to discuss here. However, I will say there is not much difference between 98.5 and 97 AFUE after you look at the big picture.

You can save money on your gas bill by buying a high-efficiency furnace. You can also save more by making the ductwork is sealed tight, and your house is properly insulated. Additionally, tax credits and rebates are offered for higher efficient gas furnaces to encourage energy savings and conservation.

Modulating or Staging and Thermostat/Control Questions | Carrier Versus Rheem Gas Furnaces

You can get so much more out of a modulating gas furnace than you can a staging gas furnace. It depends on the control. Here’s a good question for the salesman if you are looking at either of these furnaces; What happens if you hook up a single-stage conventional thermostat to the system?

What happens if you hook up a two-stage conventional thermostat to the system? How will the system modulate without using the Carrier or Rheem communicating thermostat? In both cases, they will revert to staging in increments defined by the engineer. However, what are these increments, how do they compare, and how does that affect efficiency?

It’s all about control and how that control is defined. Additionally, what happens if the Carrier or Rheem communicating thermostat goes bad, and you need to hook up a conventional thermostat to get you through a cold spell until the thermostat can be replaced?

Speaking of that, is the conventional thermostat wire going to be replaced with a communicating wire for the new communicating thermostat? If so, how would you hook up a conventional thermostat in the event of an emergency?

Additional Features and Purchase Decisions - Carrier Versus Rheem Gas Furnaces

The additional features from top to bottom are nearly identical from the blower to the warranties offered. However, I would make sure to ask about extended parts and labor warranty. That is especially true if you are buying top-tier equipment. Most baseline warranties industry-wide never include labor.

Labor can be costly as more government regulations cost contractors more, so they have to charge more for their labor to make up it. All government regulations, fines, and even taxes always get passed on to the consumer anyhow. That is the reason it costs more to buy and install a new HVAC system in New York as compared to Florida unless you hire a hack who does not know what they are doing.

At least most do not anyhow.

Energy Star Rated Gas Furnaces

Both models are Energy Star® rated gas furnaces. That is especially helpful when applying for tax rebates and credits. Additionally, it helps give you confidence that the equipment has met specific testing requirements for efficiency.

Final Advice | Carrier Versus Rheem Gas Furnaces
