Zoned Air Conditioning – Is It A Right Phoenix AC Solution?

AZ Nexia Smart HomeZoned Air Conditioning Systems – Modern Style

Remember the zoned air conditioning system used by your parents? Dad’s simple cost-savings plan involved closing off registers in specific rooms of the house. Sadly to say: Dad’s plan proved totally ineffective. And in many cases, such haphazard AC zoning practices actually shortened the life of the HVAC air handler unit.

Yet the ways of old still linger: The average homeowner continues to use closed registers as a primary means of zoned AC comfort.

In this article, the home comfort techs at American Cooling and Heating reveal the pros and cons of an installed Arizona home zoning AC system.

Multi-Zone Heating and Cooling: Sharing Your Phoenix Home

Efficient and effective home comfort requires installation of a balance AC airflow system. If you live alone, zoning your home air conditioning may seem senseless. But for people with a family, daily thermostat wars can become a major problem. Some folks like a very cold home environment. Other folks prefer things a bit warmer. With standard installed Phoenix HVAC systems, family compromise is the only solution.

Multi-zone home cooling and heating offers a different type of air conditioning solution. These systems are designed to make home zoning AC quick, efficient and effective. However, multi-zone home air conditioning systems come with both advantages and disadvantages – Installation prices coming in as one of the major points of consideration.

Zoned Air Conditioning – A Simple Definition

Installed multi-zone home heating and cooling enables individual temperature control of specific divisions within your home. Certified HVAC techs examine your home, calculate best processes, and then essentially split your house into several distinctively controlled heating and cooling AC zones. In some homes, the process may be managed by installation of multiple furnaces, heat pumps or air conditioning systems. In other homes, the process may be managed by installation of electronic baffles geared to open and close on key to air flow from a central air handler. Either method enables the HVAC system to provide separate and independent temperature adjustments to each zone within the home.

Zoned AC – Pros

Benefits of a effective Phoenix home AC zoning include:

Home Zoning AC Comfort – Unlike central heating and cooling systems, multi-zone home air conditioning enables family members with personal control of temperatures zone by zone. Depending on the divisions, everyone sets sleeping temperatures to their favored positions. Likewise, kitchens can be kept cooler than living rooms. Basically, a zoned air conditioning system lets your family enjoy home comfort that suits individual heating and cooling preferences.

Trane-comfortlink-ii-thermostats-and-controllersHome Zoning AC Control – Although effective and efficient home zoning air conditioning links back to comfort, the systems offer more than mere temperature-orientated physical comfort. Modern HVAC technology enables remote and programmed control over thermostats located throughout the home. Top zoned AC systems also include fan controls, humidity management, and various energy saving options. For example: the Trane ComfortLink II Thermostat System helps homeowners reduce energy expenses – even if you are not zoning. A properly sized and correctly installed home zoning HVAC system can save your family hundreds of dollars per year in energy expenses.

Home Zoning AC Noise Management – Although modern heating and cooling equipment produces much less noise emission than the early years counterparts, integrated variable-speed fan systems provide an even greater form of noise management. Likewise with two-stage air conditioning systems: Home zoning permits maximum system-performance system-efficiency while providing quieter system operations.

Phoenix Zoned Air Conditioning Systems – The Bad News

As with all things complex, installed multi-zoning is not necessarily suitable for every home situation. AC zoning introduces two basic complications:

  1. Higher costs for parts and installation
  2. More complexity in configuration.

Home Zoning AC Systems – Increased Costs For Installation

Multi-zone heating and cooling systems cost more than standard AC systems. A correct and energy-efficient HVAC zoning system requires more equipment and a more complex duct system. Even if you convert your existing central unit, you will pay a higher cost for the changeover.

Home Zoning AC Systems – Complexity

More equipment means greater chances for future component failure. This also means that servicing and troubleshooting expenses run higher. Before switching over to a multi-zoned heating and cooling system, contact ACH for a full home evaluation. Our techs can provide you with a best-purpose Phoenix heating and cooling solution for your home.

Has Your Mesa Home Installed Air Conditioning Exceeded A Useful Lifespan

Installed Air conditioning MesaSurvey Reveals Performance-Deficiency As Primary Cause For Installed Air Conditioning Residential Replacement

In a recent survey of 492 HVAC contractors, researchers established a 12-14 year average replacement cycle for residential air conditioning systems. The study also showed that many homeowners opted to replace the existing system before the product reached end-of-life usefulness. In most cases the decision for early AC replacement came about due to a perception that the cooling capacity and cost of unit operation was in excess of the homeowner’s expectations (1).

End conclusion: The efficiency of AC system performance plays a major role in how homeowners evaluate the useful life of a residential air conditioning system.

Efficient Evaporator Air Flow: Key Factor In Arizona Air Conditioning Performance

According to the Energy Star central air conditioner overview report, reaping the full benefits of an Energy Star certified heating and cooling system also requires that you “take steps to optimize” the practical performance of the system (2). In other words: even when a homeowner installs a new energy-efficient central A/C, successfully achieving an increase in performance depends on the skill, knowledge and applied principles of the HVAC installation crew.

One might think that proper installed air conditioning comes with the turf. Alas, this may not reflect actual conditions. The FCC survey included field tests of 70 residential A/C systems in Arizona as well as field tests of 27 systems in central California. In both test cases, the performance of the examined units failed to meet the system manufacturer’s declared Energy Efficiency Ratio (EER). Of the 70 units tested in Arizona, the average performance deficiency came in at 40% lower than the EER rating for the given unit.

Primary cause for underperformance: Insufficient airflow across the evaporator coil.

Adequate Air Flow Critical To Efficient A/C EER Returns

Conventional air conditioning units perform two primary functions:

  • 1) Sensible Cooling… The effective process of cooling the air
  • 2) Latent Cooling… The effective process of removing moisture from the air.

Reliable residential installed air conditioning (IAC) performance is primarily dependent on a balance between moisture removal and sensible heat transfer. This can only be achieved when the unit functions with ample air flow across the evaporator coil. The technical aspects involved in A/C installation and management of air handler fan speed, load requirements and airflow control exceed the limits of this article. However defining the consequences of miss-applied system installation is simple:

  • If the airflow over the coil is too high, the system is compromised. Moisture removal falls short, and fan power gets elevated.
  • If the airflow is too low, reduced system cooling occurs, and the system EER falls short. Furthermore: Extreme hindrance of airflow can cause icing of the evaporator coil. Likewise: Continuous problems with icing can lead to refrigerant flood-back. End result may even include early failure of the system compressor.

The dry Arizona climate typically equates to a low latent/humidity factor. When a Mesa home A/C system is correctly installed, years of maximum-performance efficiency become readily possible. Furthermore, if a home system is not aged-out but is rather suffering from major installation problems, correcting the errors can effectively restore new life to an older air conditioning unit. In essence, if your new energy-efficient home air conditioning system is incorrectly installed, it may actually perform nearly as badly as your aged and inefficient replaced unit.

Tips From American Cooling and Heating For Avoiding Poor AC Performance

It may be that your failing home cooling system is merely the consequence of a poorly installed unit. Or perhaps, time has played a role in the lack of adequate system performance. External conditions can change, wherein new obstacles now hinder the airflow to your external condenser unit. Duct sealant can fail and cause air leaks. Even in-duct grime can be a problem. Before discounting the efficiency of your Mesa home air-conditioning system, consider the steps of proper AC installation as listed below. An American Cooling and Heating home AC checkup can answer all of your questions, and if a new unit becomes the preferred solution, ACH will ensure that your system is correctly and effectively installed.

The following list offers no specific order, but the principles for correctly installing or configuring an air conditioning system remain true even if the system is aged. When installing a new HVAC system, American Cooling and Heating air conditioning technicians:

  • Allow ample indoor room for installation and future system servicing
  • Before positioning condensing unit, consider the noisy factor on neighbors as well as home occupants
  • Install sufficient air return and cool air delivery registers
  • Position condensing unit in an area free of objects that can create hindrance to airflow
  • Position system thermostat(s) for most effective heating and cooling response to home conditions
  • Prior to system installation, apply reliable duct-sizing tactics
  • Properly insulate attic ducts
  • Provide an access path cleaning the evaporator coil via a door into the duct or the furnace
  • Use effective and product-recommended duct sealing components
  • Verify correct and exact refrigerant charge
  • Verify that unit meets manufacturer-specified airflow rate
  • When possible, install ductwork inside the region of air-conditioned space.

Trane HVAC affects Arizona Lifestyle


Arizona AC Energy Consumption Exceeds National Average

Global Warming Plot Of NASA GISS DataRising Arizona Temperatures Increase Arizona AC Energy Consumption To Twenty-Five Percent

From the U.S. Energy Information Administrations “Quick Facts” report concerning the Arizona state profile: 25-percent of the Arizona home energy consumption goes into home air conditioning (1). That’s four times the national average for energy usage directed into home cooling. On the plus side, heating Arizona households require less energy than the national average. In fact, the yearly average energy usage in Arizona homes runs at 26% less Btu of energy per home than does the typical U.S. home.

Then comes another negative side. The bulk of the consumed household energy goes toward Arizona AC equipment, equipment that typically operates from electricity, a relatively expensive means of creating energy. Furthermore, the typical Arizona household puts out around $1,700 per year on electricity. That’s roughly 14,000 kilowatt-hours consumed per home. According to the EIA report, more than 90% of Arizona households reap the benefits of installed and functional air conditioning — and 86% of those units are central AC systems.

Note that the expenses and energy consumption is averaged based upon an average Arizona home square footage of 1,798 feet. Larger homes require more cooling performance at a higher rate of energy consumption.

What Rising Temperatures Means To Your AC Lifespan

If purchased as a reputable manufacturer’s brand name and installed by a reputable and experienced HVAC installation company, you can expect 15 to 20 years lifespan from a central air conditioning system (2). But it is not just about the type of equipment and the quality of the installation. Usage and maintenance also play a major role in the lifespan of your home cooling system. And the say the least: Arizona AC usage leaps high above the national average.

Battling year after year of exceptionally smoking summers accelerates the rate of wear and tear on any home cooling system. However, you can help reduce the labors of the unit.

It begins by making certain that your unit is right-sized for your Arizona home. Ask your Arizona home AC expert about two-stage air conditioning system. Due to less on-and-off cycling, the two stage units tend to last longer than other type central units.

More tips…

  • Chose an established, reliable and experienced Arizona AC installation company
  • Follow up with routine maintenance
  • Change the air filter before it becomes a problem
  • Take care of your outside condensing unit
  • Schedule an annual maintenance plan with your local dealer.

 Climate Change Affecting Arizona AC Lifespan

According to the 2013 State of Arizona Hazard Mitigation Plan Risk Assessment, the on-going effects of climate change are evoking increased temperatures throughout the American southwest. Arizona is no exception. Since 1895, summer temperatures have been on the rise, topping the 20th century average summer after summer throughout this century. 100-plus degree days come more and more often. The 1981-2010 maximum July temperature in Phoenix and surrounding areas comes in at 110-plus.

Yet metropolitan Phoenix, Arizona remains among the fastest-growing urban regions in the U.S.. This adds to theLiving with asthma cover increase in temperatures. By the year 2000, the nighttime minimum central Phoenix temperature was up by 9 degrees F. All of it comes together in a cascading effect that impacts animal, plants and humans, which in turn means that more and more demand is placed on your in-home Arizona AC system.

But rolling back the effects of climate change is going to be a long slow process. In the mean time, you still need to stay cool. So take care of existing air conditioning system, and when the repairs begin to outweigh the value of the unit, call American Cooling and Heating for an immediate and cost-effective cooling system replacement.
