Some Sign Show Time to Replace Your Air Conditioning System

Nowadays air conditioners have become crucial for us in order to lead a comfortable lifestyle. But remember, you need to ensure proper maintenance of the air conditioner so that it can perfectly manage its purpose of cooling the room when the temperature outside rises.

Regular maintenance ensures that the air conditioner lives a longer and more energy-efficient life.

When your AC malfunctions and cannot keep your home comfortable, it’s time to replace the system.

But when it comes to replacing the HVAC system can put homeowners in a fix as it requires a significant investment. They must also consider whether it is worth spending more money to get a more energy-efficient system.

The following signs indicate it’s time to replace the existing air conditioning system.

1. Thermostat Is Malfunctioning

The thermostat is the brain of an HVAC system that manages all the components of AC. There are two types of thermostats –

Programmable Thermostat – You can preset the heating and cooling choice using a programmable thermostat. Then the thermostat automatically maintains the temperature all day.

Non-Programmable Thermostat – A non-programmable thermostat works manually according to your direction.

When the thermostat is malfunctioning, your AC might turn on and off repeatedly. You also might not be able to read the correct temperature, and the temperature of your house might not match your programmed settings.

If these things happen, check whether the thermostat is working properly and whether it has batteries installed.

Contact a trained and licensed HVAC specialist to examine this complex electrical component to avoid other costly damages. They can also tell you which option is best for your HVAC system.

2. Little To No Air Flow

When you notice that the AC is on but does not cool your home as before, it is an obvious sign indicating your HVAC system needs to be repaired or replaced.

The air circulation issues, such as no or weak airflow from the AC, are often due to damaged and leaky ducts, blocked vents, or malfunction of the air handler. A broken motor or a blower fan can also cause a lack of airflow.

Turn off your AC immediately, and contact a professional to evaluate the total repair costs. The bottom line is when your HVAC unit is not performing up to its optimum level, it’s wise to replace it with a new model when the repair cost brings only a little benefit.

3. AC Is Blowing Warm Air

A broken AC unit can make the indoor temperature of your house uncomfortable both in the summer and winter seasons. When your vent is blowing warm air when the air is supposed to be cool, it means that your HVAC system is malfunctioning.


If there is a problem with the AC compressor, your HVAC system is low in refrigerant, or the evaporator coils of the AC are frozen, it usually blows warm air.

When the compressor on your Ac unit doesn’t turn on you’ll need a licensed HVAC tech to troubleshoot the problem. But remember, the cost of refrigerant can be more expensive than installing a new cost-efficient unit.

4. Odors Come From The AC

When you experience unpleasant or musty odors coming from your AC, it means there are molds in and around your HVAC unit.

Mold spores usually grow in a dark environment with dust and debris and in places where moisture exists. Plus, they thrive in warm air. Therefore, when your HVAC system lacks regular and proper maintenance, it can easily become the ideal breeding ground for bacteria, mold, and mildew.

Once you identify that your HVAC system is mold-contaminated, take the necessary steps immediately. Otherwise, with the blowing air of AC, mold spores can spread throughout your home and can cause severe health issues for you and your family members.

When you smell the smoky odor from your AC, it indicates that the AC unit has a problem with wiring insulation.

No matter how you define the smell, call an expert technician to evaluate the repair cost when something uncommon happens to your system. Then you need to weigh the cost of these expenses with the cost of buying a new one.

5. Humidity In The Air

The purpose of an air conditioning system is to control the moisture levels in your home. When you observe that the indoor atmosphere of your house is as humid as the outdoor weather, this indicates your system requires a recalibration.

The high humidity level inside the home is not only uncomfortable and unpleasant but also peril if kept unaddressed for a long time.

When your home’s humidity level is more than 60%, the air will become too wet, and thus your home becomes a breeding place for pests, molds, and rots. Eventually, it will pose different health risks, such as headaches, heatstroke, dehydration, heat exhaustion, etc.

On the contrary, when your home does not have enough humidity and the humidity level is below 30%, the air will become too dry. Plus, it will become peril for the structural integrity of our home.
