Top 10 Signs You Need a New HVAC Unit

HVAC system short-cycling? Repair and maintenance costs through the roof? Can’t achieve a consistent temperature or manage to keep your home cool? It may be time to invest in a new HVAC system. At Lex Air Conditioning and Heating, our Carrollton HVAC replacement team knows all the common indicators that it’s time to replace your HVAC system, and we want to share them with you. Below are the top 10 signs that you need a new HVAC system. 

1. AC Unit is Blowing Warm Air

It’s never a good sign if your air conditioning system is blowing warm air rather than cool air. If your air conditioner is blowing warm air, it could be a sign that your HVAC system is not functioning properly. A number of issues could be causing this problem, including a refrigerant leak, a malfunctioning compressor, or a clogged air filter. In some cases, these issues can be repaired, but in other cases, it may be necessary to replace the entire HVAC system.

2. Poor Air Flow

Weak air flow from your air conditioner is another sign that your HVAC system may need to be replaced. This issue can be caused by a number of factors, such as a clogged air filter, a malfunctioning blower motor, or leaky ductwork. While some of these issues can be addressed with repairs, in some cases, a new air conditioning unit may be necessary to improve air flow throughout your home. Newer air conditioners may have more efficient motors and fans that can move air more effectively, resulting in better circulation and more consistent temperatures throughout your home. New HVAC systems are also more reliable, reducing the risk of breakdowns and the need for frequent AC repairs.

3. HVAC System is Making Loud Noises

If your air conditioning unit is making strange noises, there may be a problem with the unit that could require replacement. Unusual noises and strange sounds coming from air conditioning units can be caused by a variety of issues, such as worn-out bearings, damaged fan blades, or a failing compressor. While some of these issues can be repaired, in some cases, replacing the entire AC unit may be necessary. A new AC unit will have more advanced technology that can reduce noise levels and provide quieter operation.

4. Bad Odors Coming From HVAC Unit

If your AC system is emitting strange odors, it could be a sign that there is a problem with the unit that requires replacement. Foul smells coming from air conditioning systems can be caused by a variety of issues, such as mold or bacterial growth inside the unit or ductwork, a malfunctioning heat exchanger, or a gas leak. These issues can pose health risks to you and your family and can even be dangerous. While some of these issues can be addressed with repairs, in some cases, it may be necessary to install an entirely new system to eliminate the source of the odors.

5. The Need for Frequent Repairs

If your HVAC system needs frequent repairs, it may be a sign that it is time to replace the unit altogether. Frequent breakdowns can be caused by a variety of issues, such as worn-out parts, an outdated system, or poor installation. While some of these issues can be addressed with repairs, frequent breakdowns can quickly become expensive, time-consuming, and inconvenient. In many cases, it may be more cost-effective to invest in a new air conditioner that is more reliable and efficient rather than put all your money into repair costs.

6. High Humidity in Your Home

If your cooling system is causing high humidity levels in your home, it may be a sign that the unit is not functioning properly and needs to be replaced. High humidity levels can be caused by a variety of issues, such as a malfunctioning thermostat, leaky ductwork, or oversized or undersized AC units. These issues can lead to discomfort, increased energy bills, and even mold growth, which can pose health risks to you and your family. While some of these issues can be addressed with repairs, in some cases, it may be more cost-effective to invest in a new unit that is properly sized for your home and has more advanced technology to better control humidity levels.

7. Water Leaks / Rusty HVAC Unit

If your old HVAC system is leaking water or showing signs of rust, it is likely that the unit is reaching the end of its lifespan and needs to be replaced. Leaking water can be caused by a variety of issues, such as a clogged drain line or a cracked condensate pan, and can lead to water damage, mold growth, and even electrical hazards. Rust on the unit is a sign that the metal components of the system are deteriorating and may eventually lead to a major breakdown. When it gets to this point, in many cases, it is more cost-effective to replace old HVAC systems to prevent further damage and ensure reliable operation.

8. High or Rising Energy Bills 

If you are experiencing high or rising energy costs, it may be a sign that your old air conditioner is not functioning efficiently and needs to be replaced. Older units or units that are not properly maintained can consume more energy than necessary to heat or cool your home, leading to higher utility bills. Likewise, units that are too small or too large for your home can lead to inefficient operation and higher energy consumption. Upgrading to a new HVAC system can provide better energy efficiency, which can save you money on your energy bill over time. Newer units are also built to meet higher energy efficiency standards, which can save you even more money on your energy bills. At the end of the day, investing in a new system can provide a better return on investment by improving your home’s energy efficiency, saving you money, and providing greater comfort.

9. HVAC Unit Still Uses R22 Refrigerant

If your HVAC unit still uses R-22 refrigerant, it may be a sign that the unit is outdated and you need a complete replacement. R-22 refrigerant is a type of refrigerant that is being phased out due to its harmful impact on the environment. As a result, the production and importation of R-22 refrigerant has been banned in the United States, making it increasingly expensive and difficult to find. If your unit still uses R-22 refrigerant, it may be more costly to maintain and repair as the supply of the refrigerant continues to decrease. Newer HVAC units use alternative refrigerants that are more environmentally friendly and efficient, such as R-410A. Upgrading to a new HVAC system that uses alternative refrigerants can provide you with better energy efficiency, improved indoor air quality, reduce your carbon footprint, and provide a more sustainable option for your home’s heating and cooling needs. It is also worth noting that upgrading to a new unit can increase the resale value of your home while also ensuring compliance with environmental regulations.

10. HVAC System is More Than 10 Years Old

If your HVAC system is more than 10 years old, it may be time to consider replacing your old system. HVAC units typically have a lifespan of 10 to 15 years (with proper maintenance), and as they age, they become less efficient and more prone to breakdowns. Older units may also use outdated technology that cannot keep up with the energy-efficient standards of newer units. Upgrading to a new HVAC system can provide you with better energy efficiency, improved indoor air quality, and greater comfort. Newer units may also come with features such as programmable thermostats that can help you save money on your monthly energy bill. Additionally, a newer unit may require fewer repairs and maintenance, which can save you money in the long run.
