Air Conditioning System Installation in Oak Lawn, IL

New Air Conditioning System Service

Oak Lawn HVAC handles all types of air conditioning system installations in the Cook County area as well as surrounding cities includng Chicago, Maywood, Des Plaines, Oak Park and beyond. Don’t hesitate to call us to install a new air conditioning system. We will help to evaluate your home on site to determine exactly what kind and capacity air conditioning system you need. We will recommend what we think you need and give you an estimate.

There are several steps to take when choosing the most appropriate air conditioning system for your home or business. First, you need to understand the differences between the types of systems, as well as the pros and cons to each. Having a system that isn’t the right fit for your home can cause damage to the system itself, and cost you a lot of money in unnecessary energy bills.

Systems are available in a variety of sizes to match the size of your home. Bear in mind, that this does not mean bigger is better. A system that’s too big will turn on and off frequently, leading to added wear and tear on its component parts. You really want to get the sizing just right, and that’s where we come in.

Our team of experienced technicians are always on hand to answer all of your air conditioning system installation questions. We’ll guide you through the process of choosing a type and size of air conditioning system that will be perfectly suited to your needs and the layout of your home.

Before installing a New AC System, there are important areas that we professional HVAC providers from Oak Lawn HVAC consider. We always take into account the room heights and other variables that are significant to be able to have an efficient and effective system.

Having the right cooling system is important so you can save on unnecessary expenses that may be caused by the wrong unit. We do a proper and necessary assessment, we sort out the details to you, then suggest the best possible unit fit for your home or business!


Having airflow that is slow because it’s restricted or too fast is not efficient. This can cause the unit to overheat, be stressed and forced to use excessive fuel which will not allow the unit to deliver cool air properly. We always make sure that the airflow generated by the unit is calibrated properly.

You should also consider having an HVAC Maintenance agreement to ensure that the system remains properly adjusted to deliver adequate airflow.  Oak Lawn HVAC is your go-to professional service for periodic maintenance.


We can accurately calculate your home cooling load and arrive at a unit which is the appropriate size and capacity. Electricity isn’t cheap. That’s why having an efficient, properly sized unit for your home and business is important to keep expenses to a minimum.

AC Units vary in sizes and capacity rated in tonnage.  A one-ton air conditioner can cool 12,000 BTUs (British Thermal Units) in an hour. The precise meaning is that a one-ton unit can cool 12,000 pounds of water by one degree every hour. Proper size and capacity will result in the most efficiency.


Proper ductwork, baffling and flow measurement will result in an efficient system. Our experience will ensure that the ductwork we install or adjust will be the most efficient. Leaky or poorly baffled ductwork can result in excessive operating costs.


Keeping the unit full of refrigerant is one contributor to efficiency. Loss of refrigerant contributes to loss of cooling power and increases the load on the compressor. If the cooling abates noticeable, it might mean a leak. Periodic maintenance would also check the refrigerant level.
