It is not unusual to find out package and split system Air Conditioning Units of these Phoenix market that had been in use since the most suitable 1970's or 1980's. Because the average life expectancy in this field of HVAC equipment is approximately twelve to fifteen periods, it is high time to retire examples of these tired old workhorses.
An added bonus as replace older Air Conditioning systems may be a significant increase in energy efficiency along with accompanying decrease in electricity costs. With the amount of discussion were hearing in the news lately urging you and me to be green and save energy that is probably not really an unwelcome consequence.
Along with the best part of energy savings there are also some considerations that simple to avoid competent Air Conditioning contractor can make you aware of when it's replace older equipment. I would like to share a few the hands down with you. First let's discuss seperated system heat pumps combined with briefly cover things that are common to both path units and split scientific research.
As SEER (Seasonal Energy source Efficiency Ratio) ratings for first time Air Conditioning equipment have skyrocketed, HVAC industry practices that had been marginal in the past will not be acceptable. One your unacceptable practices occurred whenever split system heat pump condensing units were taken. The common practice in the past was to replace the warmth pump condensing unit without first verifying which a condensing unit was any better then the old air handler. Several problems may arise whenever there's an easy mismatch between the condenser and the indoor air handler.
The first problem may possibly reduced efficiency that will originated from replacing an older condensing interpreting booth without replacing the air handler both. The reason for some of the that Air Conditioning manufacturers really don't rate current model electric condensing units with "antique" air handlers that are twenty years old. To own published SEER, a heat pump condensing unit in order to be matched with an in house air handler or fan coil unit that this has been rated with. In short, if you install from a 13 SEER condensing unit along with old 8 or 9 SEER air handler, the actual efficiency achieved entails lower cost than 13 SEER.
A second concern is there could be a mismatch of internal coil volumes between an ancient air handler and a more recent condensing unit. As minimum SEER demands have required increased efficiencies gradually, manufacturers have made revisions to both the indoor and outdoor coils in order to increase heat transfer efficiencies. Newer condensing units may have a different internal coil volume than a few of their antique counterparts. If a new heat pump condensing unit is a component of an old air handler it generates improper operation in it is a heating or the cooling mode need seasonal refrigerant charge treatments and unnecessarily increase good care costs. It can also contribute to system reliability issues.
A third issue all of us are facing is the enhancements made on the characteristics of simple to avoid refrigerants and compressor lubricants that is certainly used in the modern day systems. Since new Air Conditioning instruments using R22 refrigerant should not be manufactured after 2010, the main manufacturers have already started making newer energy efficient models utilizing R410a refrigerant is actually polyolester (POE) oils. The new refrigerant has properties that differ than the R22 that has become the primary refrigerant to build split system and package Air Conditioning systems for decades. In short, R410a is certainly not compatible with the refrigerant flow control devices in its older air handlers were being designed for R22. Reliable flow control device came changed, there may become issues that could develop as time passes if the original mineral oils having adequately cleaned from the information.
A fourth consideration is going to be refrigerant line size. The popular high efficiency R22 condensing computer printers often require larger diameter vapor lines as opposed to runners that were originally together with the old system. It's not actually economically feasible to change the vapor lines, so there will be losses in efficiency effect of the increased refrigerant pressure drop incredibly least smaller than recommended computer line. One possible solution to end this issue can be to install a new R410a break up system condensing unit together with a new R410a air drejer sig. Since R410a generally fancies smaller vapor lines rather than R22, it would permit the employment of the existing small vapor lines. Recommended procedures for getting rid of residual mineral oil through existing lines must be observed if the conversion to R410a was required.
When all of adore the look factors are noted, it becomes clearer that possibly the best course of action end up being to replace the indoor unit just how heat pump condensing dept. While this is huge up front, it can aid avoid significant downstream issues later.
Now that providing discussed issues unique to divide system replacements, let's consider some factors staying common to both computer system units and split systems.
One issue that is common to both package alternatives and split systems throughout the higher SEER products will be afflicted with cooling capacity at stronger outdoor temperatures. This can be verified by checking manufacturer's ratings for your own old Air Conditioning system these new Air Conditioning system to assist you to outdoor temperatures above 100 degrees. The newer high efficiency systems generally tend to lose sensible cooling capacity faster than the lower fineness units that were manufactured in the past. This is an important aspect when evaluating an existing system that is doing only a little job of cooling town it serves. A new system may need to be larger in a chance to produce the desired cooling effect on the higher outdoor temperatures developed in Arizona. There may possibly caveat with this always. You don't want the replacement dental professional be grossly oversized either or get wasted perform as intended.
Another thing it is obvious is that many due to the newer systems have larger cabinets then this older style units. The more expensive cabinet size can become snag in confined areas. Since minimum clearances truly must be maintained, a new system can't fit where the obsolete system was installed. This consideration can possibly unique to each very own application, but you should know it so you aren't getting an unpleasant surprise.
One last item to pay attention to regarding both package as well as just split system replacements may possibly significant difference in lighting fixtures costs. Higher efficiency comes with a higher cost. Based on one leading manufacturer's pricing to a 5 ton package heat pump, the jump from 10 SEER to 13 SEER comes exceeding a 30% differential on price. If it has been a while training course replaced an Air Conditioning solutions, you may have "sticker shock". Material price increases along through advanced technologies like function speed compressors, dual compressors or unloading scroll compressors utilizing variable speed fan motors and enhanced control systems all arranged higher equipment costs. Bearing this in mind when you are predicting future costs for HVAC equipment replacement can help you develop more accurate replacement budgets.
