HVAC Heat Pump Package Unit Restriction
Pump Package Unit
Greater SEER Alternative Air Conditioning And Warmth Pump Programs
It is not strange to discover package deal and split technique air conditioning models in the Phoenix marketplace that have been in use since the 1970's or 1980's. Due to the fact the average life expectancy of this sort of HVAC devices is about twelve to fifteen a long time, it is substantial time to retire some of these tired outdated workhorses.
An additional bonus when you substitute older air conditioning programs can be a substantial boost in electricity performance with an accompanying lower in energy charges. With the volume of discussion we have been hearing in the news recently urging all of us to be green and help save electricity that is possibly not heading to be an unwelcome consequence.
Along with the excellent news of energy cost savings there are also some factors that the qualified air conditioning contractor will make you mindful of when it is time to substitute older products. I would like to share a handful of of them with you. Initial let's discuss split technique heat pumps and then briefly cover factors that are widespread to equally bundle units and split methods.
As SEER (Seasonal Vitality Performance Ratio) ratings for new air conditioning equipment have improved, HVAC market practices that have been marginal in the past will no longer be acceptable. 1 of these unacceptable practices occurred every time split method warmth pump condensing models were replaced. The typical practice in the previous was to substitute the heat pump condensing unit without having 1st verifying that the new condensing unit was compatible with the previous air handler. Numerous troubles may come up anytime there is a mismatch among the condenser and the indoor air handler.
The very first dilemma is the decreased performance that will consequence from changing an older condensing unit with out changing the air handler at the very same time. The cause for this is that air conditioning suppliers do not price current model warmth pump condensing units with "antique" air handlers that are 20 a long time outdated. To obtain the printed SEER, a heat pump condensing unit must be matched with an indoor air handler or fan coil unit that it has been rated with. In other words, if you set up a new 13 SEER condensing unit with an previous eight or nine SEER air handler, the actual efficiency reached will be less than thirteen SEER.
A second concern is there can be a mismatch of the internal coil volumes between an older air handler and a more recent condensing unit. As minimum SEER mandates have necessary elevated efficiencies more than the years, suppliers have made enhancements to each the indoor and outside coils in order to increase heat transfer efficiencies. Newer condensing units may have a different internal coil volume than some of their antique counterparts. If a new heat pump condensing unit is installed on an previous air handler it might outcome in improper operation in both the heating or the cooling mode that will need seasonal refrigerant charge adjustments and unnecessarily boost services charges. It can also lead to program reliability concerns.
A 3rd concern we are all dealing with is the distinction in the traits of the refrigerants and compressor lubricants that are getting utilized in the new techniques. Considering that new air conditioning gear employing R22 refrigerant cannot be manufactured soon after 2010, the top producers have currently started off generating more recent large efficiency types utilizing R410a refrigerant and polyolester (POE) oils. The new refrigerant has properties that are quite distinct than the R22 that has been the major refrigerant for split program and package deal air conditioning methods for decades. In brief, R410a is not compatible with the refrigerant flow handle gadgets in the older air handlers that were designed for R22. Even if the movement manage device could be modified, there may possibly also be concerns that could build above time if the first mineral oils are not adequately cleaned from the technique.
A fourth consideration is the refrigerant line size. The new high efficiency R22 condensing models usually call for more substantial diameter vapor lines than those that were initially set up with the outdated system. It could not be economically possible to exchange the vapor lines, so there will be losses in performance as a outcome of the improved refrigerant strain drop in the smaller sized than suggested vapor line. A single achievable resolution to resolve this concern would be to set up a new R410a split system condensing unit and a new R410a air handler. Given that R410a usually needs more compact vapor lines than R22, it would allow the use of the present smaller sized vapor lines. Advised techniques for taking away residual mineral oil from the present lines would have to be noticed if the conversion to R410a was implemented.
When all of the over aspects are taken into consideration, it turns into clearer that the extremely best program of action is to exchange the indoor unit along with the warmth pump condensing unit. Even though this is far more pricey up front, it can help avoid considerable downstream concerns later on.
Now that we have discussed issues unique to split technique replacements, let's think about some elements that are typical to both bundle units and split systems.
One situation that is frequent to each package deal models and split systems in higher SEER products is diminished cooling capacity at greater out of doors temperatures. This can be verified by checking manufacturer's ratings for the aged air conditioning technique and the new air conditioning technique at outdoor temperatures over 100 degrees. The newer substantial performance techniques usually are inclined to shed wise cooling capacity a lot more quickly than the reduce efficiency models that were manufactured in the previous. This is an essential factor when evaluating an current method that is undertaking only a marginal task of cooling the area it serves. A new system might have to be bigger in capability to generate the sought after cooling effect at the greater outdoor temperatures we see in Arizona. There is a caveat with this also. You don't want the substitute program to be grossly oversized both or it will not carry out as intended.
Another thing you will discover is that many of the more recent systems have bigger cabinets than the older style models. The bigger cabinet size can turn into an concern in confined locations. Considering that minimal clearances should be maintained, a new program may not fit wherever the previous method was set up. This consideration will be distinctive to each certain software, but you ought to be conscious of it so you don't get an unpleasant surprise.
1 previous item to be informed of concerning both package deal or split technique replacements is the substantial difference in equipment costs. Higher performance comes with a increased price tag tag. Primarily based on 1 foremost manufacturer's pricing for a five ton package heat pump, the leap from ten SEER to 13 SEER arrives with more than a thirty% differential in price. If it has been a although since you have replaced an air conditioning method, you may have "sticker shock". Materials value boosts along with the use of advanced technologies like variable pace compressors, dual compressors or unloading scroll compressors along with variable pace fan motors and enhanced control techniques all lead to increased products costs. Trying to keep this in mind when you are projecting future fees for HVAC products replacement can help you produce more accurate alternative budgets.

Frequently Asked Questions...
Is $7300.00 too much to pay for a central air/gas furnace/service package?
This was a quote for a Kenmore unit. I opted not to go with a heat pump, since my home has gas connections, and I usually use EM Heat anyway in the winter. This quote is for a 4 ton unit, 10 yr warranty, unlimited service calls, etc. I have 1,925 sq. ft. of living space.
Answer:
I would read that fine print on that warranty real close. Kenmore is a substandard product that they charge way too much for. Personally as a former employee of Sears Service (20 years go) I still wouldn't want to depend on Sears.
Getting rid of the heat pump is a good idea especially if it gets really cold where you live. Unless you have a geothermal heat pump it's not worth it in a cold climate. The price actually doesn't sound that bad, but it's the quality of the equipment and the installation/service that I would be worried about.
You'll get down the road in 5 years and find out that certain parts and/or labor are not covered by Sears. Don't believe everything the salesman says. GO through the contract with a fine tooth comb.
Also find out where the equipment is manufactured. If it's from China or Mexico I would not take the risk. I work for a major manufacturere of commercial HVAC equipment and I can tell you first hand that even our equipment that is manufactured in Mexico and China is poorly made made by people that make very little money and have no education. You might not think it matters, but haven't you noticed a short life in everything you buy these days? Many times it is screwed up right out of the box. It's hard to find anything that is actually manufactured in the US any more, but it's a good idea to pay a little extra if you can find it.
Most of Trane residential products are still made in the US, but that's soon to change. Trane was recently bought out by a major player who is famous for moving manufacturig to 3rd world countries and cheapening the product through lean manufacturing techniques. The shell will look the same and the price will be the same if not higher, but everything from the sheet metal parts, electronics, compressors, fan motors, wiring, and oil will be cheap immitations made to look the same, but cost them a lot less to build. I suggest buy a Trane now before they are just like the rest.
