Most often, one half of an HVAC system fails, but the other component is still operational. If your outdoor compressor or indoor evaporator has given out unexpectedly, you may be wondering if it's okay to just replace that unit and have it added to the existing system. This might seem like a smart, cost-saving strategy, but here are a few good reasons why it's better to buy an entire system.
The efficiency ratings for traditional split systems are always based on two matched components working together. If you replace one component, it won't reach its efficiency potential, because it's limited by the older unit.
If your HVAC system is a mix of old and new components, the older equipment is forced to work harder. This increases the risk that the component will break down at the peak of the season when it's under the most strain. When you have an entirely new system, you'll have the benefit of many years of trouble-free, reliable service.
With a complete new system, you'll not only save on energy consumption, but you'll also save on the cost of repairs and maintenance over its lifespan. You'll lose out on these savings if you mix and match components, plus you'll still have to buy half a system when the older component gives out.
Buying a complete system not only brings an improvement in energy efficiency, but it also gives you an opportunity to benefit from the latest technology and features. For example, you can upgrade to a system with a variable-speed motor, thermal expansion valve, scroll compressor or innovative coil design that provides better humidity and temperature control and boosts comfort.
If you replace just one unit of a split system, you'll lose out on warranty coverage for equipment defects, because it's impossible to have half a system installed to meet the manufacturer's specifications.
