Your HVAC system is a machine, meaning it has a dedicated lifespan beyond which it may not be effective. Most units can serve for up to 15 to 20 years, especially when properly maintained. However, even the best system will not last as long as it can when neglected. How long your heating and cooling unit lasts depends on how well maintained it is.
Fortunately, you will not have to wake up one morning to a surprise when your unit stops working. There will be several warning signs before this happens, and it helps to watch out for these signs, especially before a major season. You do not want to be caught off guard with a malfunctioning unit when winter or summer is around the corner. Below are some of the most common signs that indicate the need for a system change.
Top Signs that Your AC Needs to be Replaced
Not every repair need or malfunction is an indication that you need a new HVAC system. Often, most issues can be fixed quickly, and the unit will be back to normal. However, specific signs should not be ignored. They include:
- Frequent repairs
- The unit’s age
- Excess leakage
- Increasing energy bills
- Strange sounds
- Bad odor
Constant Repairs
An HVAC unit will need occasional repairs to ensure it functions properly. While repairs are okay and expected, it is different if the machine experiences constant repairs. If you have to call an HVAC professional twice or more a month, there may be a problem that needs a permanent fix. The cost will add up quickly when you have to start replacing parts constantly. At this point, you’re usually better off investing in a new HVAC system.
Age Factor
Once your unit gets to a decade old, it will either start having many issues or give up altogether. Although, with proper maintenance, most units will get to the second and third decade without any significant mishaps. However, as a homeowner, it is advisable to start saving for a new HVAC system once your old one clocks a decade old.
You may not have to replace it that soon, but at least when the time comes, you will not be caught off-guard. Due to air conditioners being exposed to extremely harsh conditions, especially outdoor units can shorten their lifespan. The technology of the unit also affects its longevity. Modern units can comfortably serve for a minimum of 15 to 20 years, while older models can last 10 to 12 years without extreme maintenance measures. Therefore, the lifespan of any unit can prolong if the owner is careful about proper maintenance.
Excess Leakage
It’s normal to have condensation around the AC unit. However, this should be minimal and not alarmingly conspicuous. You should call your HVAC technician immediately if you notice large pools of water around the AC. If the problem is not fixable, you may have to explore the possibility of getting a new unit to avoid exposing your family to the hazards of leaking coolants.
Skyrocketing Energy Bills
Higher energy bills are probably one of the first warning signs you will experience when things go wrong. The unit becomes inefficient, which translates to the consumption of more energy. When it is time to replace the HVAC unit, you may experience a sudden rise in energy consumption reflected in the monthly energy bill. When this happens more than once, you should be concerned about whether the AC is nearing or has exceeded its expected lifespan. It’s safe to start budgeting for a new unit since the situation will only worsen.
Strange Noises/ Sounds
You know your AC and the sounds it typically makes when all is well. When suddenly you begin to experience different weird noises, you need to have the unit checked. The unit may be having difficulties requiring a simple repair or could be a warning sign of something more serious. An HVAC technician can confirm and fix the problem. However, if the noises are persistent or keep changing, it may be time to consider upgrading your HVAC unit.
Bad Odor
Musty smells, burning smells, and other strange or unexpected scents should be carefully considered when they occur around the AC. Musty smells are indicators of mold growth due to poor humidity. This may mean that the AC is failing or struggling to keep up, especially if the area has low humidity. Strong smells of burning wires and plastic may also signify that the unit is overworking and thus overheating. This could also result from the wear and tear of components. A thorough assessment by a professional HVAC technician may be necessary.
Regardless of the problem, you need to have an HVAC professional check and confirm your suspicions. An expert can recommend necessary repairs or if it’s time for an upgrade.
