How Do You Know When to Replace Your HVAC?

When maintained and cared for properly, systems last 10–15 years. Early replacement planning will help you extend the life of your current system while also taking the necessary steps to start saving money for when the time comes to buy a new unit or system. It’s probably time to hire a professional to do a system diagnostic test if you notice any of the following:

• Repair costs are more than half as expensive as purchasing a new system. As an AC unit ages and degrades, you may frequently find yourself paying for system maintenance and eventually replacing some of the system’s important components. When that starts to happen, it’s necessary to determine whether replacing the parts will actually end up saving you any money over time. It’s time to “out with the old and in with the new” if the cost of repairs is greater than half that of a new system. A new system will be a wise investment for you, saving you money over time and lowering your current energy expenditures.
  
  
• Uneven temperatures: A one-zone system will cause temperature swings in homes with many levels. A significant difference in temperature between rooms, even those on the same level or between floors, may point to a problem with your system. To determine whether a simple thermostat calibration is required or if a more serious problem, such as leaking ductwork, exists, contact a service specialist.
  
  
• Do you even recall the installation date for your HVAC system? Your computer is older than ten years. Every 10 to 15 years, according to the Department of Energy, air conditioning systems should be replaced. The basic components of any HVAC system, despite being robust, will begin to deteriorate after ten years, depending on how frequently they are used and how well they are maintained. In systems older than 10 years, a type of Freon (R-22) is employed that is not just outmoded but also very harmful to the environment. When a contemporary unit is installed, you will save money on energy expenses and help reduce carbon emissions.
  
  
• Problems with humidity: In the winter, your home is too dry; in the summer, it’s too humid. Problems with humidity are a sign that your ducting may need to be repaired. Although expensive and time-consuming, for some people, this is a do-it-yourself project. However, for the majority, it is advisable to leave the installation and replacement of ductwork to experts.
  
  
• Your Energy Bills Keep Rising: It is reasonable to anticipate seasonal increases and declines in your energy bills, but each particular month should be roughly the same as the previous year. Your HVAC system has to be maintained and may be replaced if you experience exceptionally high energy bills in an unanticipated month. As a system ages, it gets less effective. Your HVAC system will last longer and operate more efficiently with regular maintenance, especially monthly air filter changes.
  
  
• You Have Poor Interior Air Quality: During the summer, your air conditioner has a major role in the indoor air quality of your home. If you observe mold, mildew, dust, or odd humidity levels, the air conditioning unit may be damaged, and your system may need to be replaced. Never forget that a NIOSH (National Institute for Occupational Safety and Health) study found that poor ventilation was to blame for almost 50% (52%) of Sick Building Syndrome instances.
