When to Replace a Heating and Air Conditioning Unit
When deciding whether or not to repair or replace an HVAC system, consider its age.
The average residential heating and air conditioning system can last anywhere from 15 to 20 years when properly maintained. However, HVAC systems are heavy pieces of machinery that are susceptible to malfunctions and component failures. Even if they’re properly maintained and repaired, an HVAC unit eventually needs to be replaced. The challenge is determining when it is time to replace the unit. Here are a few signs that a heating and air conditioning unit needs to be replaced.
The unit is old
When deciding whether or not to repair or replace an HVAC system, consider its age. A properly maintained unit should last anywhere between 15 to 20 years, depending on the amount of usage. This number can also vary based on how often the unit is serviced and tuned up. When considering an HVAC unit replacement, consider if the cost to have the unit repaired is going to cost more than half the cost of a replacement. If so, it’s more practical to replace the entire heating and cooling system.
Energy bills are increasing
As a heating and air conditioning unit ages, it has to work overtime to keep the home at a comfortable temperature. This means the heating and cooling systems are going to be using more energy and costing more money in monthly electric bills. When the bills start increasing, have a professional HVAC contractor replace the current unit with a new, energy-efficient system that functions better by using less energy.
The system is making unusual noises
While it is normal for an HVAC unit to make some noise while functioning, there is a problem within the system if the noises become unusual, and the system could be on its last legs. Instead of waiting and being left without a proper heating and cooling system, have the system serviced and, if necessary, replaced immediately.
The system needs frequent repairs
When a heating and air conditioning system breaks, professional AC repair services can perform prompt repairs. However, if these repair services start coming in more frequently, the unit is likely nearing the end of its life. Instead, use the cost of repairs to have a brand-new unit installed before the old unit malfunctions.
Uneven temperatures throughout the house
When an HVAC system isn’t operating as it should, there’s often a noticeable difference in temperature between rooms, with one room often having weaker airflow than another. An old and inefficient furnace can result in some rooms of the house being colder or warmer than others, which usually goes hand in hand with an older duct system not properly distributing heat to where it needs to go in the home. If the temperature throughout the house is inconsistent, it may be time for a new heating and air conditioning system.
Every home should have a functioning HVAC system, especially during the extreme summer and winter months. Every unit is bound to need replacement eventually, so homeowners should know when the time is right. Don’t wait for the unit to break down altogether; keep these signs in mind to know when a heating and air conditioning unit should be replaced.
