There is a reason why the HVAC is called a "system" – the furnace and AC must be working together as one unit. These days, manufacturers who design the heating and air conditioning units do so in a way that ensures the components complement each other. Unfortunately, this is not the case with many older units or models. A mismatched furnace and AC unit is likely, and could lead to various potential issues. HVAC experts call this approach the "Frankenstein" system because the individual components are not designed to work together.
This guide will show you the potential risks and how you can remedy a mismatched HVAC system.
A mismatched furnace and AC can still function. This is one reason why many homeowners are oblivious to the potential issues that could arise from this until they see the high energy bills or are burdened by the cost of constant repairs.
The following are some potential issues and risks that could arise from a mismatched system.
The efficiency ratings of the furnace and air conditioning units are based on matching systems. Therefore, these units are designed to work together to achieve the ideal efficiency performance.
A mismatched system can result in reduced energy efficiency. Whether each unit is a different brand or installed independently of each other (old furnace and new AC, or vice versa), you can expect efficiency issues with your mismatched HVAC system.
For example, the older components can keep the new unit from running efficiently if you have an older AC with a newer furnace. The lower efficiency means other parts must work harder to achieve the ideal temperature.
The lack of efficiency in your mismatched HVAC system could lead to other potential issues, such as the next one: decreased lifespan.
The mismatched system could also cause the entire system to be reduced in its lifespan. This results from a lack of efficiency and the need for constant repairs because of the inability of each component to work seamlessly as a unit. It creates more wear and tear on the mechanical parts of the individual units.
It is only a matter of time until your HVAC system fails and you need to replace the entire system, not just the components of each unit.
The lower warranty from a mismatched system could result from having to replace one or a few of the components of each unit. When you replace any parts, you void the warranty for the furnace or AC.
Voiding your warranty could be problematic because you would have to shoulder the cost of repair and parts replacement. Finding a suitable replacement part might be challenging if you have an old unit. Even if you buy from the manufacturer, these parts could be obsolete or only available at a higher cost.
Installing a mismatched furnace and AC is common. Even if the incompatible components are still functioning, they are not encouraged and should be replaced, if possible. There are plenty of reasons to choose a matching HVAC system.
Think of the furnace and the AC units as fraternal twins. A system that matches provides optimal efficiency and maximizes the system's performance. Since they are designed to work as a system, there is a dependability for each component in the system.
A highly efficient performance of your HVAC system also means a longer lifespan. The internal components are not subjected to constant wear and tear. It also means less internal damage resulting from the system's operation compromising performance.
It is also worth noting that technology changes over time. If one of your units is outdated, it is time to replace it with a new one that matches the same performance as the other. Addressing these issues will ensure your family stays comfortable and healthy. By keeping your home comfortable, you achieve the intended purpose of installing the system in the first place.
Lastly, a matched system is an economic investment. While you might spend more initially to replace or install a matched HVAC system, you could save on repairs and maintenance costs. An efficient and dependable system won’t suffer from damage or regular breakdowns. You could save money on repairs and lower your energy bills. With energy costs being one of the primary costs involved in maintaining your home, these savings can make a real difference over time.
It’s not necessary to replace a mismatched system; however, it is recommended if you want to maximize the performance of both units.
The units might function now, but problems could arise in the long run. These problems could worsen over time, which would mean more costs for you. A matched system can last 10-15 years, whereas you must replace incompatible systems every 3 to 5 years.
Matching the components of your HVAC system offers guaranteed compatibility. Every component is designed to fit perfectly and to work as one unit. You won't have to worry about system breakdowns.
To avoid any issues with a mismatched furnace and AC, expert contractors recommend that you install them as one system. Ideally, get each unit from the same brand or manufacturer so you can achieve better performance and longevity.
Investing in a new HVAC system can be an issue for many homeowners, especially those on a tight budget. It is crucial to speak with a trusted and reliable HVAC contractor who can make the best recommendations for improving the overall efficiency of your heating and cooling systems at home.
The experts can inspect your current system and quote you for the service based on your individual needs. Hence, choosing a trusted contractor from the start is vital since they can build the right system for you, which helps you save more in the long run.
