It is not uncommon to 1970, see package and split system air conditioners in the Phoenix market was that, in use or in 1980. Because the average life expectancy for this type of HVAC systems is about twelve to fifteen years, it is time to retire some of these tired old horses.
A bonus when you replace air conditioning systems, legacy costs a significant increase in energy efficiency with an accompanying drop in energy.With the level of debate we should all be pushing the news lately green and energy savings that could have been a side effect of his hearing.
Together with the good news of saving, there are some considerations that the competent air 'conditioning, the contractors will know when it's time to replace old ones. I want some of them to share with you. First of all discuss split heat pump system, and then brieflyCovering two units and common set of split systems.
SEER (Seasonal Energy Efficiency Ratio) ratings increased by new air conditioning systems as required by the industry practices that have been in the past is no longer acceptable, marginal HVAC. One of these unacceptable practices occurred when split heat pump condensing units have been replaced. The common practice in the past, the heat pump to replace the condensing unit without firstwhether the new operator of condensers was compatible with the old air. Some problems may arise when a discrepancy between the condenser and the indoor air handler.
The first problem is the low efficiency is the same result this time, instead of a condensing unit above, without replacing the air handler. The reason for this is that producers can not vote conditioning heat pump condensers current modelwith the "old air handler", the twenty years. To reach the Seer published a condensation heat pump will be assessed must be coordinated with an interior air handler or fan coil was to know that in other words, if you have a new 13 SEER condensing unit with an old 8 or 9 SEER air handlers, the actual efficiency is achieved less than 13 SEER
A second concern is the gap between the volume of air between an old indoor coil Handler and a condensing latest. Year SEER minimum efficiency increased over mandates, manufacturers have made improvements coils for Both the indoor and outdoor areas to increase the efficiency of heat transfer. Modern Condensing Units May be an internal coil volume different from some of their colleagues old. When a new heat pump installed on an old air handler, condensing unit, can cause a malfunction of both> Heating and cooling, which will require seasonal adjustment refrigerant charge and unnecessarily increase, reduce service costs. It may also contribute to problems of system reliability.
A third issue that we all face is the difference between the properties of refrigerants and compressor lubricants, which are used in new systems. Since the new air conditioning systems with refrigerant R22 can not be manufactured by leading companies have already started in 2010that new models with high efficiency refrigerant R410a and ester (POE) oils. The new refrigerant has properties that are very different decades of the R22 air conditioning as has been the primary coolant for the split system and systems for the package. In short, it is not compatible with the refrigerant R410a, device control in older air handlers that have been developed for the R22. Although the flow control device could be modified, it may be that the questionscould develop over time if not properly cleaned, the ore from the original system.
A fourth consideration is the size of the refrigerant line. R22 The new high efficiency condensing units often require larger diameter than the steam lines that were originally installed with the old system. Can not be economically feasible to replace the steam lines, which is loss of efficiency due to increased refrigerant pressure drop in smaller than recommendedSteam Line. Solution to this problem would be to set a device to install a new split system condensing R410a and R410a air a new manager. R410a Since usually takes less than R22 steam lines, allowing the use of smaller lines existing steam. The recommended procedures for removing residual mineral oil from existing lines would have met if the conversion to R410a was to be implemented.
If all these factors into account, were seizedIt is clear that the best approach to replace the condensers much, the internal drive with the heat pump. This is the most expensive front can help avoid significant problems later downstream.
Now that we talked about issues unique system of replacement of Split, we consider some factors that are both units of the package and split systems.
One issue that is common to both units and split systems, package products more reduced SEERCooling capacity at higher temperatures. This can be controlled 100 degrees from the manufacturer rating for the old and the new air conditioning when the temperatures up. The new systems, performance is usually more sensible cooling capacity to lose faster than less efficient units that have been produced in the past. This is an important factor when evaluating an existing system to make only a marginal roleThe cooling of the space being served. A new system can be larger than the cooling capacity for the desired effect at higher temperatures we see in Arizona to produce. There is a problem with this. You do not want the replacement system is not oversized or too coarse or is intended.
Another thing is, you will notice that many of the newer systems are more mobile units of the old style. The larger body can become a problem in enclosed spaces. SinceMinimum distances must be respected, a new system can not adapt when the old system had been installed. This consideration will be unique for each specific application, but you should be aware so as not to have an unpleasant surprise.
A final element to be aware, both in terms of the separation package or system to replace a significant difference in equipment costs. Greater efficiency comes with a higher price. Supported by a major manufacturer prices for 5 tonsPackage heat pump, the jump from 10 SEER to 13 SEER exceeds 30% difference in price with. If there is a given that while they have replaced an air conditioning system, you can have "sticker shock." increases prices of materials using advanced technologies such as variable speed compressors, compressors or dual exhaust scroll compressors with variable speed motors and better control of all costs to carry more equipment.In this context, if the cost of future plans to replace the HVAC system can help replace more accurate budget.
