Out With the Old, In With the New


Hello there, and welcome back to the Legacy Heating and Air Conditioning blog! As HVAC specialists who have been helping New Braunfels area residents with their HVAC needs for years now, we have seen just about every situation that you can think of. While we make every effort to repair our clients’ HVAC systems and keep them running as efficiently as possible, occasionally a unit is beyond our ability to save. Like any home appliance, HVAC systems must sometimes be replaced. In the first of a two part blog series, we are going to go over some of the signs that indicate an HVAC system needs to be replaced and cannot simply be repaired. If by the end of this blog you realize that we are describing your HVAC system, please get in touch with us by phone or by filling out our contact form. Now, to learn more about the HVAC replacement signs, keep reading below.

Sign 1: Age of the System


If your home’s HVAC system is over 10 years old, chances are that you are missing out on quite a bit and it may be time to replace your system. Overwhelmingly, newer HVAC systems are Energy Star rated. This means that in comparison to older systems, these newer systems require a fraction of the amount of energy to complete the same task as older units do. In some cases, newer systems can save homeowners upwards of 40 percent on their monthly utility bill. In addition to these impressive savings, newer HVAC units come with digital thermostats that are much easier to use and allow the homeowner to program in daily heating or cooling cycles. This helps decrease the amount of energy that your system uses by limiting the amount of time that the unit is cooling or heating the home. While the investment in a new system may seem like a lot up front, in just a few years the new system will pay for itself as you spend less on energy.

Sign 2: Age of the Parts


While you may take a look at your older air conditioner and determine that it is good to go for another 10 years, you may want to take a look at the internal components before making any major decisions. Beginning in 1992, a shift began to happen in the world of air conditioning. It was in this year that the industry began to phase out R-22 refrigerant, commonly known as Freon, and began to replace it with a newer, more efficient refrigerant known as R-410A. This refrigerant, known as Puron, had some major effects on the construction and efficiency of air conditioners and affected homeowners whose HVAC units are on the older side. Newer air conditioners are designed to make use of R-410A which is able to absorb and release more heat than R-22, resulting in a compressor that can run cooler and a reduced risk of compressor burnout due to overheating. If your air conditioner is not designed to handle R-410A, you’re losing out on a major efficiency upgrade.

Sign 3: Improper HVAC System Size


In some instances, people will try to save money and install an HVAC system in their home that is smaller than what is suggested by the manufacturer. While it might seem like a good idea at the time, eventually the smaller system will come back to haunt you. If your home has an HVAC system in place that is too small, it will be unable to properly heat or cool your home. Not only will you home not be the temperature that you want it to be, the system will work harder than it needs to while attempting to bring your home to the temperature that you have set on your thermostat, resulting in an increased utility bill. In the world of HVAC, size matters.
