When To Upgrade Your Air Conditioning System


Summers are hot in the Elburn area, so how do you know when it is time to upgrade your home air conditioning system? Contacting your local home Chicagoland HVAC experts is best, but read on for several indicators that homeowners can identify.

Stepping into a cool house after a long day in the heat is a great feeling and having an air conditioning system that is operating at its peak performance is a huge factor. While many people only think of replacing the AC system in their home after it has completely failed, there are plenty of other ways to determine when and if an air conditioner installation makes sense. 

Air conditioning that does not shut off causes high energy bills and additional wear and tear on the unit and leaves the home’s temperature less than comfortable.  One of the most common problems that get overlooked is when the system runs continuously. This symptom can occur for many reasons, including a leaking condenser coil, an improperly adjusted thermostat, or even loose ductwork. If your system has a leak or worn-out ductwork, it may be time to replace the AC unit.

An abnormal noise from any part of the air conditioner is another indicator that you should upgrade your home air conditioner. A buzzing noise could mean the contactor is starting to fail and will not be able to turn the system on. Clicking noise from the outside (coil) unit could indicate a bad air conditioner compressor, while a rattling noise inside the home could mean the blower unit is out of balance. 

Reducing your energy bills is another reason to consider upgrading your home’s air conditioning system. While HVAC systems can last up to 15-20 years with proper maintenance, the technology used in home heating and cooling changes every year. A new system can be up to 40% more energy efficient than an older system installed just 10 years ago.

Knowing how an air conditioning system works also helps understand how an HVAC upgrade can make sense. While it seems that the airconditioner just makes cold air and blows it into the home, it actually removes heat and humidity from the air inside the house and never takes air from outside. The warm air inside is pulled into the air return vent, where it passes across the evaporator coil, and the refrigerant transfers the heat to the outside condenser coil. Ductless air conditioners, sometimes called mini-split ac systems, work in the same manner. Since there are no ducts, these systems are usually designed for one room although one outside unit can serve as many as 5 inside units.
