Air conditioner installation is not a decision that should be taken lightly. You will need to consider many factors before you decide which AC unit to buy and how much energy it will use. In this blog post, we’ll discuss 5 things to keep in mind when installing an air conditioner so you can make the best possible choice for your home or business. Read on for tips about sizing, efficiency ratings, ductwork systems, insulation levels, and more!

First of all, if you don’t have much expertise in ac installation we recommend that you hire a professional HVAC contractor. It’s also worth noting that if your central air conditioner is more than 15 years old or it’s been providing less heating and cooling power during warm seasons over time, then it may be a good idea to replace it.

Some Air Conditioner Installation Points To Consider

Before you get a new AC installed or get the old one repaired, you need to keep in mind the following points:

What Is Your Budget?

A home central air conditioning system can cost from a few hundred dollars to over $20,000. The first thing you need to do when considering an AC installation is deciding how much money you have available for the purchase and maintenance of your new unit.

This also means that you need to decide if you want to hire a contractor or do it yourself. If the budget is tight, then you can consider buying an AC with lower capacity and power consumption levels that are energy efficient in order to save on energy costs for your home.

When evaluating window AC units, you should ask about the energy efficiency of each unit. If it isn’t ENERGY STAR certified, chances are that it will cost more to run than a window unit with this certification. Some window units and split systems also have an EER rating listed on their packaging; this is how much power they consume relative to running on electricity and power consumption.

If the budget allows it, make sure that there are enough vents and ducts around the house so that the air conditioning system is installed perfectly.

What Size Air Conditioning Unit Do You Need For Your Home?

Installation costs will vary based on the type and capacity of the central air conditioning system required, which is determined by the square footage of the area to be cooled. You need to take into consideration the number of people in your household, as well.

Costs can be estimated by multiplying the square footage of the area to be cooled (in feet) times $14 per foot ($280), then adding installation charges.

Does Your Home Have Any Special Needs?

If your home has any special needs, like a fire suppression system or an electric heating unit that can’t be disconnected for the installation process, make sure to tell the AC contractor so they can plan accordingly.

Ask the designer or the administrative authorities of your condominium or complex what type of central air conditioning system, if any, is available.

Some people are more sensitive to the noise an AC unit produces than others; you should always consider this when deciding where to place it in relation to other areas of the home.

Which Type Of Insulation Should Be Used Around The Ducts?

You need to use insulation around the ducts to keep them from freezing during cold winter months. Insulation is also good for preventing air leaks, which can cause you to lose a lot of money in energy costs each year. Ductless mini-split can be used to save money as well.

There are two main types you’ll come across: Fiberglass or spray foam insulation. However, window AC units should not have to be insulated much.

Why Should You Install Central Air Conditioning?

One reason to install central air conditioning is that window units can be more expensive than other types of AC installation. It also allows you to cool your entire home with one unit, instead of a window unit in every room.

Central Air Conditioning might not be the best option if you live in an area that doesn’t have many hot days each year. So it really depends on your personal preference and is related to your needs.

Average Cost of AC Installation?

The Average cost of AC installation is $1000-$1500 for a window AC unit.

Some other factors to consider are the type of window and how big your home is. For example, if you live in an older house with large bay windows that take up most of one wall, this might be more expensive than installing two or three window units in different rooms

The average installation cost of a central air conditioning system is  $1500-$5000.

This is the most expensive out of all options, but it’ll cool your entire home with one unit rather than window AC units in every room. It also takes up less space and works much faster than window units are able to.

There you have it! If you’re looking for a new air conditioner installation, you need to find a reliable HVAC contractor.

How to Find the Right HVAC Service For AC Installation?

It can really be difficult to find the right HVAC contractor. A couple of things to keep in mind:

– Ask for references and past job experiences, you can always ask if any window AC is installed on the property as well. This way you’ll know that they have experience with window units and central air conditioners alike.

– Check their license number or company name on the internet or in business listings.

– Ask for the service call fee, this could be a big deal if you’re not prepared.

It can also cost less than window AC units in every room. It also takes up less space and works much faster than window units are able to.
