6 Signs It’s Time to Replace Your Heating & Cooling System


Air quality and temperature control are two major factors that dictate the enjoyment of your home. It’s comforting to know that your home will remain snug throughout winter yet stay fresh and cool during those hot summer months. An HVAC system is crucial for regulating heat and air circulation, so having one in prime working condition is optimal.

One of the most challenging aspects of heating and cooling your home is the HVAC system cost. It is one of the most expensive appliances you will install in your home, giving you even more reason to ensure it’s running well. A poorly functioning system can drive up utility costs and drain your wallet due to repairs. At some point, it’s important to realize that your system isn’t worth using anymore. If you notice any of the following signs, perhaps it’s time to consider replacing your heating and cooling system.

1. The System Runs More Often and for Longer

Old and worn-out systems start up more frequently because they need to work harder to reach the intended temperature. After several years of use, coils and motors can no longer operate at full capacity. They take longer to produce desired temperatures and can’t circulate air as effectively or efficiently. Replacing individual parts can extend the system’s life, but if you notice increased running time and difficulty reaching certain temperatures, it may be time to replace the system.

2. The System Is Making Strange Noises

Although heating and cooling systems are rarely silent, they should operate quietly. When internal parts become worn or damaged, they may start to rattle, grind or squeak during operation. This is a major red flag that something is wrong, so act quickly to avoid unnecessary costs. Sometimes a simple replacement or a service can fix this issue. However, loud noises can indicate there is irreparable damage to the blower or furnace. Be sure to monitor your outdoor unit’s condition, as you may not notice unusual sounds as quickly outside.

3.  Repairs and Replacements Are Becoming More Frequent

All heating and cooling systems require repairs and replacements from time to time. Filters, coils, motors and fans can become damaged or worn, reducing your unit’s efficiency. While this is to be expected, you shouldn’t need repairs and replacements regularly. If repairs and replacements are becoming more frequent, it often makes more financial sense to replace the entire unit. If several key components break down, it’s time to upgrade to a new system.

4. Increasing Utility Bills

One of the first signs of a damaged heating and cooling system is increased utility costs. An energy-efficient mini-split system generally equates to cost savings; blocked pipes, clogged filters or damaged coils can cause the system to run inefficiently. Having to work harder to achieve the desired settings, you’ll notice a sharp rise in your monthly bill. An HVAC system loses efficiency as it ages, so, once you notice a significant decline, it could be time to replace the unit.

5. Poor Temperature Regulation

Temperature inconsistencies can be very frustrating, particularly during peak summer and winter months. Poor temperature regulation can mean your system is lacking the power to heat, cool and circulate air adequately. From thermostat issues to motor damage, temperature problems are often expensive to repair. In an aging system, there is an increased likelihood that they will reoccur. Create a healthier home environment by upgrading to a new system.

6. The System Is Old (10+ Years)

If your HVAC system is more than 10 years old, the technology is likely to be outdated and far less efficient than modern appliances. In addition, after the 10-year mark, most older appliances begin to lose efficiency and experience operational issues. Even a well-maintained system is on its last legs after 10 years. This is the time you should consider a newer, more efficient heating and cooling system.

Maintenance Is Key

No matter what type or brand of heating and cooling system you have, proper maintenance is crucial for functionality and efficiency. Ensure you clean each unit regularly, replace worn parts, and have your system professionally inspected annually. This can contribute significantly to cost savings and the longevity of your system.
