When is it time to pull the old unit off the roof and install something a little more up to date? The answer to this question varies based on each customer’s specific needs. However, there are a few common points to consider when evaluating whether to repair or replace a heating and air conditioning system.
- When major repairs are diagnosed as being necessary. Examples of major repairs could be cracked heat exchangers, leaking condenser or evaporator coils, or bad compressors. If a system is under warranty, or still in good condition over all, then it may be acceptable to simply make the repair. To assess what the best decision is, the entire unit should be evaluated.
- The age of a system also plays a critical role in this decision. In our experience most commercial units start to have an increase in mechanical issues between 10 and 12 years of age. This average life expectancy can be greatly affected depending on how well the unit was maintained, the specific application it served, and the environment around the system.
- Incentives. The laws are continually changing and manufactures are producing more efficient equipment to meet the new regulations. As an incentive to push consumers to purchase more environmentally conscious equipment, incentives are often offered by power companies. If there is an incentive available then it may be the opportune, and economically sound time, to replace your HVAC equipment.
- Energy prices are continually on the rise. As HVAC units become more efficient they consume less energy which helps reduce the cost of staying comfortable. Taking these savings into consideration, along with some of the other factors listed above, is a key factor in helping one make the decision whether or not to replace their older HVAC system.
- Cost-Benefit of investing in costly repairs of an older system. Typically, when addressing a major repair, as mentioned above, it is wise to consider the investment over a longer period of time. For example, even on a system that is between 6 years and 10 years old, the price of a compressor replacement could be around 35% of the total cost of replacing the entire system. Additionally, with an older system, there are no guarantees that the other components in the system that were not repaired are going to last through the next heating/cooling season. The immediate benefits of replacing the entire system are renewal of Manufacturer warranty for the whole system, up-to-date technology, and compliance with current energy efficiency recommendations.
