 
  An old heating or air conditioning system will eventually wear down through time. There will come a time when your system could not make you comfortable anymore despite the constant adjustment. Once this happens, it is time for you to upgrade your heating or air conditioning system.
INDICATIONS THAT AN UPGRADE IS NEEDED
Is your system more than a decade old? If it is older than 10 years, then chances are it is time for you to upgrade. Machines and appliances can run efficiently for 10 years, anything beyond that and it loses its energy efficiency. This is especially true if your machine has been running for longer periods. If you will notice, your energy consumption slightly increases despite using the same appliances for years and more or less for similar number of hours.
DO AN ENERGY ASSESSMENT
Once you think you need to upgrade, check for air leaks first. The decrease in efficiency and the increase in energy consumption may be due to air leaks in your home and within your HVAC system.
Employ an energy efficiency professional that can perform a thorough energy assessment on your home. They are equipped with the right tools to assess energy leaks properly. For instance, they can perform the blower-door test to detect energy leaks. If a leak is detected, you can identify the location and seal it. In addition, you can also insulate your home so it becomes more energy efficient.
CONTACT A NATE-CERTIFIED HVAC PROFESSIONAL
After sealing leaks and insulating your home and you still find that you need an HVAC upgrade, contact a qualified HVAC professional. As much as possible, hire a NATE-certified technician to ensure that a load calculation is performed, a properly sized HVAC system is chosen for your home or office and installation is properly implemented.
