Providing it receives routine maintenance, the average HVAC system lasts for about a decade. However, if your AC unit is running constantly or short cycling, it is probably time for a replacement.
Increased Energy Bills
An HVAC system will last a decade or more with consistent maintenance, but even the best systems wear down over time. If your system has reached the end of its life, replacing it can save you energy bills and future repairs. If you notice an increase in your power bill, especially during the summer, it’s likely due to a malfunctioning AC unit. The system works harder to reach the temperature set on your thermostat, which results in higher energy consumption. A loud or erratic sound from your HVAC system is another sign you need to call an expert for a repair. Loud clanking or rattling sounds are signs of an existing problem. And can be a symptom of more serious issues like refrigerant leakage.
Unusual Smells
A well-functioning HVAC system should provide clean and healthy air in every room of the house. Unusual smells like mildew, mold, and dust are signs of damaged HVAC equipment needing replacing. Strange sounds like clunks, bangs, thuds, and rattling noises can signal that the system is wearing out. Loud sounds may also indicate a problem with motors, blowers, fans, or low refrigerant (Freon) levels. If you notice your energy bills are increasing, this is another sign that it’s time to replace your old system. A newer unit will be more efficient, saving you money in the long run. The best way to determine whether or not you need a new HVAC unit is by calling experts like GoGreen Heating and Air to have your current system evaluated and repaired or replaced as needed. An expert technician will advise you on the best option for your home and budget.
Loud Noises
When a loud clunk or banging sound comes from your HVAC system. It could mean something is loose and needs to be tightened. This can be anything from a panel to an internal fan or motor. It is best to have it looked at by a professional so they can diagnose the problem and fix it before it gets worse. Another noise that is often heard is a whistling sound. This is a sign that there is a refrigerant leak. The system should be turned off immediately; a licensed technician must inspect the unit. Rattling and buzzing sounds are also a bad sign. This indicates a problem with the capacitor on your unit, or it may be a loose fan or electrical component. Both of these are major problems that need to be fixed right away. If left unchecked, they can cause much more damage and cost you more money in repairs.
Increased Dust
An HVAC system that has received regular maintenance should operate quietly. Any unusual sounds, clunks, bangs. Or hissing should be treated as a serious problem that must be repaired or replaced immediately. Keeping your HVAC system well-maintained with air filter changes (every three months) should keep it from producing excess dust in your home. However, if your air conditioner or furnace constantly produces more dust than usual. It could be a sign of broken fans, low Freon, or other problems that require a professional HVAC technician to address.
A well-functioning HVAC system is essential for healthy indoor air. Look for these signs of HVAC problems before it is too late and your home is at risk for higher energy bills. Uncomfortable temperatures, unsafe odors, or dusty living areas. Your HVAC system should last for decades with routine maintenance and prompt repairs. However, even with the best care, all systems eventually wear out and must be replaced.
