The HVAC system is one of the most important components of your house. When it is uncomfortably hot, the system helps to lower the interior temperatures of your house to levels that are comfortable for you and your loved ones. When the weather is very cold, your HVAC system warms the interior of your house. Like any other equipment, your HVAC unit is subject to wear and tear. Most HVAC problems can be repaired, but there comes a time when the entire unit has to be replaced. Below are some of the signs that you should tell you that it’s time to consider an AC replacement. 
Your HVAC Unit is Old
If you ask how long an HVAC unit is supposed to last, your HVAC expert may not have an exact answer. This is because the lifespan of an HVAC unit really depends on its brand, how well the unit was installed, and how well it is maintained. But generally, an HVAC unit should serve you for between ten and fifteen years. Therefore, if your unit is older than 10 years, it is wise to start thinking about replacing it even if it is currently running well.Your Energy and Repair Bills are Going Up
As an HVAC unit gets older, its efficiency tends to depreciate due to wear and tear. As such, your energy bills will start to go up and so will the cost of repairs and maintenance. For you to save yourself from the rising cost of operation and maintenance, then it is wise for you to replace the entire unit.The Unit Runs Constantly
After using your HVAC unit for many years, you may realize that it kicks into overdrive to keep your house temperatures comfortable on hot summer days. However, if your HVAC unit does not stop on regular days, it means that the unit no longer has the capacity that it used to have, and consequently, you should start thinking of replacing it.Uneven Temperatures
If your HVAC is not cooling or warming your home evenly, then there are several issues that your system may be having. For instance, it could be that one or several thermostats are not working properly. You need to call an HVAC expert to determine if changing the thermostats is going to solve the problems or if you need to consider an AC replacement.Leaks and Moisture Around The Unit
Condensation around an HVAC unit is normal. However, excessive leakage means that there is a serious problem. If the refrigerant is leaking and there are pools of water around your unit, then you have to call a reliable Godfrey, IL HVAC expert immediately and start thinking about replacing the entire unit.
