Things have changed in the past few years. The air conditioning industry has become more sophisticated and more diverse than before. And while shopping for an air conditioner is a relatively straightforward process, there are things you should know before buying one so you can make the right choice. This is a list of the top 12 things you should know before buying an air conditioner for your home or office.

Types of Air Conditioning

Types of Air Conditioning

To make the right choice when you are buying an air conditioner, you have to have all the facts. Different types of air conditioners can fit the needs of almost any home . These different types are:

  • Window Units
  • Air Conditioner Units
  • Central Air Conditioning Systems


You’ll want to buy from trusted air conditioning companies in Essex. Not only will you have access to a wide selection of models, but you’ll also have access to customer service and technical support, as well as warranties and repair options.


If you’re looking for an air conditioner that cools just the rooms you need it to, look into window units or Portable AC. If you want something that cools the whole house, standard central air conditioning units are your best option.

Performance Rate

This number gives you an idea of how large the unit can be based on the square footage of the area it’s cooling. For example, a 3-ton unit can cool a room up to 3,000 square feet. A 5-ton unit can cool an area up to 5,000 square feet, and so on.

Maintenance Required

Maintenance Requirement of Air Conditioner

Maintenance requirements vary depending on your unit; some require regular filter changes, and some require more involved cleaning and maintenance procedures throughout the year. Be sure to read through any included manuals or ask customer service if there’s anything specific about maintenance. 

Is It Portable?

You may not be planning to move any time soon, but if you are in the market for an AC unit and have a good sense of your plans, it’s worth checking to see if the device is eligible for portability. This is particularly important if you’re buying an apartment or condo unit with limited access to the AC system. If the device can’t be moved easily, it will not do you much good.

What Does It Cost?

This is a general question that applies to most situations, but it’s especially applicable when buying an air conditioner. You need to understand how much you’ll be paying out each month on your new unit before purchasing. The best way to figure out your monthly costs is by looking at how much energy the AC uses and how much electricity costs in your area.


Compressor of Air Conditioner

You should consider the type of compressor you want in your air conditioner. If your home uses gas for heating and cooling, then an electric-start compressor will save you time and money by not requiring any additional equipment such as gas lines running into your house. you can also choose an RMS multi-head split system for saving your operating costs.

Electric Load

How much electricity does the AC use? You don’t want something that will overload your circuits in the long run, especially if you live in an older building.

Noise Level

Air conditioners are generally noisy, but some models are significantly louder than others. If you’re a light sleeper, this is a crucial detail to consider.


How much does that AC weigh? While this may not seem like a big deal if you plan on leaving it in place year-round, it can be a major inconvenience if you need to move it elsewhere or take it with you when you move.

Temperature Settings

Temperature Settings of Air Conditioner

Not all settings will get you to your desired temperature at the same rate. When shopping for an AC, pay attention to what the specs say about how much cooling time is needed for each setting.

Although understanding what to look for when purchasing an air conditioner can seem daunting, it’s not too difficult.
