Is Grandaire A Good AC Unit

Grandaire AC makes decent air conditioners. But as you might expect, it has its pros and cons.

Pros of Grandaire AC

Here is what sets Grandaire AC apart from the competition.


Grandaire units cost less than most air conditioners on their level. However, their prices will differ depending on the tonnage size and model type. For instance, you’d expect a Grandaire 14 seer 4 tons ac to be cheaper than a 16 SEER 4 tons ac

Easy to Install

Like most AC units, Grandaire ACs are easy to install. So, you will not have a hard time finding a qualified contractor to handle the installation.

Decent Warranties

Grandaire offers decent warranties on its air conditioners. It has a 5-year warranty on parts, which increases to 10 years if you register within 90 days.

The brand also offers a 12-month unit replacement warranty. That means you can get a brand new unit within this period should anything go wrong.

The following table compares warranties for different Grandaire models.

Cons of Grandaire AC

Grandaire AC, just like other brands, has its flaws. We discuss some of them below.

Low Seer Rating

The WCA6 is the unit with the highest SEER rating at 16. The others are at 13 and 14. Air conditioners with a rating lower than 16 can only be effective in northern climates, where temperatures are lower.

The WCA6 makes it, but only just. You might want to consider using it part-time.

Few Units

Grandaire only offers three ac units. That leaves you with very little in terms of options. Some models like Bryant have as many as 18 ac units in their products catalog.

Not Ideal for Southern Climates

Only the WCA6 can be effective in southern climates where temperatures are higher. Even then, it is best suited for part-time use.

High Noise Levels

The average decibels for an entry-level air conditioner is around 73 decibels. Again, only the WCA6 falls below the average. The rest produce between 71 to 79 decibels.

Compared With Other Brands

How does Grandaire compare to other AC manufacturers on the market? We pit the brand against Goodman and EcoTemp below.

Grandaire vs. Goodman

Both brands make decent air conditioner units. However, Goodman’s units are more efficient. For example, its highest-rated AC has a seer rating of 18.

The units from Goodman are also of a higher quality compared to Grandaire. So, you should expect them to last longer.

If you want to know whether your current unit needs replacing, you need to learn how to determine the age of a Grandaire air conditioner. Technically, when an AC goes beyond 10 years, its efficiency starts deteriorating.

Which is better? EcoTemp Air Conditioner vs. Grandaire Air Conditioning

Grandaire and EcoTemp have many things in common. For one, Watsco Inc. manufactures all the products. You’ll realize that the products are similar save for the labels. They even share the same features.

The two are also affordable options. Their AC units are in the same price range, but EcoTemp is relatively cheaper.

Grandaire Air Conditioner Products

Grandaire sells a variety of HVAC products. They include heat pumps, furnaces, air conditioners, and other accessories.

Grandaire Air Conditioner Models

Grandaire offers three air conditioners with varying tonnage sizes. They all feature a single-stage scrolling compressor and noise levels ranging between 69 and 79 decibels.

Grandaire units are affordable and easy to install. However, they have relatively low SEER ratings, making them unsuitable for southern climates.

Grandaire AC Frequently Asked Questions

1.How many BTU is a 2.5-ton Grandaire ac?

Since one ton equals 12,000 BTU, we will multiply 2.5 by 12,000 BTU.

2.5 tons 12000 BTU = 30,000 BTU.

That is the same answer as in the table above.

2.My Grandaire ac is freezing up. What to do?

First, turn it off and give the ice time to thaw. Meanwhile, you can turn on the fan to allow more airflow. That will help melt the ice quicker.

Afterward, call in an AC specialist to deal with the root of the problem. Freezing can damage your unit if you don’t address it early.

3.How to change a defrost thermostat on a Grandaire ac?

First, disconnect the power. Then, unclip the defrost thermostat using a pair of pliers. The next step is to remove the wiring running through the humidifier to the compressor. Finally, replace the old defrost thermostat with the new one.

4.What size capacitor for a 2 1/2 Grandaire ac unit?

Multiply full load amps by the value 2,650. Afterward, divide the result by the supply voltage. You will find both in the owner’s manual.
