Early Signs It’s Time to Replace Your HVAC System

While waiting too long to replace your HVAC system can leave you at risk of a breakdown and other comfort issues, replacing the system too soon can result in unnecessary expenses. That’s why it’s important to identify early signs that it’s time to replace your HVAC system. 

In the latest blog from Evergreen Heating & Air, we’ll discuss some signs that it’s time to replace your HVAC system and what to look for in a new system. Contact our team today to learn more or to schedule an HVAC installation appointment in the Waco, TX area. 

Signs That You Should Replace Your HVAC System

While your heating and cooling system can’t directly tell you when it needs to be replaced, it will leave some clues behind that indicate it’s time for a new HVAC system. Pay close attention to your unit, and schedule HVAC services if you notice any of the following issues:

Poor Airflow

Many times, poor HVAC airflow is due to clogged air filters. Replacing the filter should be your first step if you notice poor airflow. However, if the issue still persists even after installing a new air filter, the problem likely lies within your HVAC system.

Poor airflow might be the result of a dirty evaporator coil, blower fan problems, or other issues. A professional should inspect your HVAC system to ultimately determine what is causing the poor airflow. Having your unit inspected sooner rather than later can help you replace the system before it completely shuts down.

Lukewarm Air Coming from the System

Whether using a furnace, air conditioner, or any other type of HVAC system, you either want warm or cool air to leave your HVAC system. However, if the air leaving your vents feels lukewarm, your home likely won’t be able to reach the set temperature. Not only does this decrease your comfort, but it also can increase energy bills, as your system will stay on for longer periods of time in an effort to reach the set temperature.

Lukewarm air can be caused by low refrigerant levels, a faulty heat exchanger, or other issues. Many times, replacing an HVAC system that is only producing lukewarm air will be a better long-term investment, as you won’t be pouring money into an older system that ultimately needs to be replaced.

The Unit is Approaching 15 Years of Age

The typical lifespan of an HVAC system is around 10-15 years, depending on factors including usage, maintenance, and efficiency. However, if your system is approaching 15 years of age, having it replaced at the first sign of any issues might be your best option. Doing so can save you money and stress, as older systems are typically less efficient, resulting in higher energy bills and more frequent issues.

Strange Noises While the System is Running

Outside of a low buzzing noise, you shouldn’t hear many noises coming from your HVAC system while it’s running. Any grinding, screeching, or scraping noises often indicate internal issues are present. If you notice strange noises coming from your HVAC system while it’s running, it’s important to address them promptly. Strange noises can indicate issues including:

  • Worn-out or damaged components
  • Blower motor issues
  • Refrigerant issues
  • Debris in the system

Leaks Around the Unit

A water or refrigerant leak can indicate serious issues. A water leak can mean that there are issues with your condensate drain line or drain pan. These are crucial components in removing moisture that forms during the cooling process.

Refrigerant is responsible for creating cool air, so a refrigerant leak can reduce the system’s cooling capacity, in addition to posing environmental risks. If there are leaks around your heating or air conditioning system, be sure to have a professional inspect the unit.

Short Cycling

Furnaces, air conditioners, and other HVAC systems operate in cycles to provide cool or warm air. If your system starts and runs for a couple of minutes, only to shut off and kick back on just a few moments later, it is short cycling. This decreases comfort, leads to higher energy costs, and can increase strain on your system. Have your system replaced to restore heating and cooling to your home.

What to Look for in a New HVAC System

When the time comes to install a new heating or AC unit, it’s important to know that HVAC systems are not “one-size-fits-all” solutions. Heating and air conditioning systems are built with different sizes, efficiency ratings, and features to meet varying needs. Here are some key factors to consider when looking for a new HVAC system:

  • Proper sizing: The size of your HVAC system should be determined based on the square footage, insulation, and layout of your home. An undersized system will struggle to adequately heat or cool your space, while an oversized system may cycle on and off frequently, leading to inefficiency and increased wear and tear.
  • Energy efficiency: Look for HVAC systems with high energy-efficiency ratings. The efficiency of air conditioners is measured by the Seasonal Energy Efficiency Ratio 2 (SEER2), while the efficiency of furnaces is measured by the Annual Fuel Utilization Efficiency (AFUE). Systems with greater efficiency ratings lead to lower energy bills and reduced environmental impact.
  • Advanced features and technology: Newer HVAC systems often come with advanced features that can enhance comfort and energy efficiency, such as programmable thermostats, variable-speed motors, zoning capabilities, and smart home integration. Decide which features are most important to you in a new unit in order to find one that matches your needs and preferences.
