How to Read Goodman Serial Numbers?

The serial number in modern HVAC unit is to encode the year and month of manufactured date of production (the unit age). Most air conditioner have their unit information in the form of sticker or plate inside the the sidewall condenser. In this article, I will show you to decode the goodman serial number.

The Goodman Serial Number Location

Your goodman air conditioner or heat pump however will usually have it’s sticker or plate mounted on the exterior of the unit. It’s located on the top, right rear area of the unit. You can see the picture below for more detail.

Goodman Serial Number Lookup and Decode

The Goodman serial number is a ten digit code that helps us identify the age of goodman air conditioner. The date of manufacture is coded in the 1st four digits of the goodman serial number. These four digits code represent the year and the month of manufacture.

Serial Number Lookup Example

Ductless Mini-Split vs Central Air Conditioners

Posted By Mas Broto

If you looking for a new air conditioning system for your home then you may be wondering if it’s better to get ductless mini-split or central air conditioning system.

When you constantly have problems with the centralized air conditioner you bought in the past, then you should read this article about ductless air conditioners and how they can be of use to you. But first of all, what exactly is this air cooling device?

Ductless Mini-Split Air Conditioning System

The ductless air conditioner is also called the split-type air conditioner. What this means is you don’t have to punch holes through your walls or windows. All you need to do is mount the air conditioning unit on your wall. The ducts of your air conditioner will be located outside the wall of your home or near the ceiling of your room. This will enable you to save lots of space as well.

This kind of unit is also commonly used in hotels and offices wherein they have rooms that do not have any wall facing the outside of the building. If you want the walls of your home to look cleaner and more appealing – without the butts of air conditioners jutting out of it – then you should buy ductless air conditioners.

Another great thing about this kind of air conditioning unit is that it is very powerful and operates silently. Certain units can even cool an entire home when functioning normally. Since the evaporator is located far from the motor of the unit, it will be able to produce cold air faster and more efficiently.

One more benefit of using this device is that you it can function as a heat pump during the winter. This will save you the hassle of buying a separate heating system for your home or office. Silence is also a very important factor when it comes to choosing the right air conditioner. You can work best and relax well when staying in a room that is serene and silent.

There are many things you need to take into consideration when choosing the right kind of air conditioner for your home.

Firstly, you need to set your budget. By having a maximum amount of what you can spend in mind, you will be able to narrow down you list of units significantly. You should also figure out how strong an air conditioner you need in order to cool your room correctly. This will enable you to choose an air conditioning unit that is powerful enough for your needs.

You should also be sure to only buy units manufactured by the best and most reputable Air Conditioner Brands. This way, you can be assured that the unit you buy will be of good quality. Also, you should have your units installed by a team of qualified professionals. This will ensure that your ductless air conditioners will work very well and for a long time to come.

Central Air Conditioning System

Central Air Conditioning System is what the most people are familiar with. It makes sense that peoples have chosen to install these kind of units in their homest. However, just because Central A/C is what we know doesn’t necessarily mean it’s to best option when choosing a new air conditioning system .

A central air conditioning system treats air at a central location and distributes it to and from rooms by one or more fans and a series of ducts. Supply ducts and registers carry this cool air from the air conditioner to the home. The air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers.

A central air conditioner is usually installed outdoors, although in some cases they may be mounted on your roof or in your attic. Because they are not part of your living areas, they are relatively unobtrusive, with only the vents showing.

Mini Split vs Central Air Conditioner – Pros and Cons

Ductless Mini-Split

Mini Split vs Central Air Conditioner – Cost

In central air conditioning, your costs are going to be dependent on several factors. The first of which is the brand of unit itself. When selecting a central air unit, you will want to look at its SEER number or its efficiency rating. The higher the number, the less it will cost you to run, but the more it will cost you upfront. For 13 SEER central air conditioning will cost around $5,000 to $9,000 for a 1,800 sq. ft. home.

Ductless air conditioners cost around $2,000 to $4,000 for a single unit for a 1,800 sq.ft. home .

After all, while this article should help get you started, it’s always best to talk to a heating and cooling professional to make sure you’re getting all the facts as they relate to your home. Both mini split or central air conditioning require a professional for correct sizing and placement so that system runs effectively and at peak performance.

How to Find AC Tonnage from Model Number?

Posted By Mas Broto

The easiest place to find AC tonnage is on the AC unit itself. Go outside to the condensing unit and look for a data plate mounted to the side. Up near the top of the label, you’ll see the model number (M/N) and serial number (S/N). The model number is where you can find the size of AC you’re looking for.

Not all air conditioning companies do this, but most will give you a 2 or 3 digit section in AC model number that says how many thousands of BTU/hour your air conditioner can cooling of your house.

If the model number on your air conditioning system lists the tons, no more calculation is needed as you now finally found the right AC tonnage of your cooling system.

Divide the BTUs on the label by 12,000. You need to use this number as the divisor because there are 12,000 BTUs per ton. The result of this calculation will be the tons of your central air conditioning system. For example, assume that your system is labeled as having 60,000 BTUs. Dividing 60,000 by 12,000 will give you 5 tons. This is the most accurate method on determining the size of your central air conditioning system when your label does not indicate the tons on it directly.

If you don’t want to do the math, here are the numbers you’re looking for and their corresponding tonnage:

 18 = 1.5 tons
 24 = 2 tons
 30 = 2.5 tons
 36 = 3 tons
 42 = 3.5 tons
 48 = 4 tons
 60 = 5 tons

The 3 digits in the model number tell you the nominal capacity in thousands of BTU/hr. Since each 12,000 BTU/hr is equivalent to 1 ton of air conditioner capacity, it’s easy to figure out how many tons of nominal capacity your AC has.

Finding AC tonnage from model number is very important and detrimental to the proper operational status of an Air Conditioning System.

If your system happens to not have the BTU or the tons information detailed, identify the AC model number on the label. Then contact a local HVAC contractor and provide them with the model number. Most HVAC contractors can look up the tonnage of the system by using the model number.

How Many Tons is my Trane Air Conditioner?

Posted By Mas Broto

You can easily identify the nominal size of your Trane Air Conditioner and Heat Pump through checking out the model number. This Trane Model Number is usually the data plate at the side of the condenser in outdoor unit. Then find the lable that provides the info about your Trane AC Tonnage.

What is AC Tonnage?

Heating and air conditioning capacities are sized in British thermal units (BTU) per hour. One BTU is equal to the heat generated by an one little candle. It’s the volume of heat required to bring up the temperature of one pound of water by one degree.

The word tonnage is used to describe the cooling capacity of an air conditioner. One ton of cooling is the rate of heat transfer needed to freeze 2,000 lbs – or one ton – of water in 24 hours. This is equivalent to 12,000 Btu/hr.

Why is AC Tonnage Important?

In some cases, bigger size is better. But when it comes to air conditioners, in some cases less is more. You should never simply buy the biggest AC unit possible, or you could end up with an oversized system.

Where to find Trane AC Tonnage?

You should look for the last two numbers of the first numbers after a cluster of letters at the beginning of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 36 divided by 12 equals 3, so the data plate below indicates the system is 3 tons.

Trane is the only brand we are familiar with that occasionally lists a two-digit number for the thousands of BTU rating that is not divisible by 6 or 12—but close.

Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 – 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons. And this is another one that is 2.5 tons.

In case you are doubting whether you have found the right two numbers, you can double check it by checking for the RLA rating. Its located the same on the data plate. RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. If you divide the RLA by 6 for older units and 5 or 6 for newer units, you should get a number that approximates the tonnage of the system.
