Phoenix Air Conditioning When Summer Takes A Break
Phoenix air conditioning and heat pumps bring home cooling during the summer and home heating during the winter. Yet the excessively warm nature of Arizona temperatures may cause a bit of lapse in winter AC maintenance planning. After all, summer reports from azcentral typically deal with record-breaking highs. For example: On Sunday June 19, 2016 temperatures in Flagstaff, Phoenix, Tucson and Yuma set various heat records. It was a day when Phoenix came in at 118 degrees while Yuma temperatures punched a record setting 120 degrees (1).
The need for severe winter weather air conditioning preservation is not foreign to regional Phoenix AZ.
Perhaps you remember the Phoenix freeze warnings during the December of 2015 NM blizzard (2). Local residents were cautioned to wrap pipes, protect weather sensitive plants, and take special care of outdoor pets. As to 2017, January should hang mostly in the mid forties, but may experience several drops to mid thirties. The following list reveals some of the recorded 2015 low:
Flagstaff – 16 degrees
Prescott – 17 degrees
Mesa – 34 degrees
AND Phoenix – 39 degrees.
In this article, American Cooling and Heating offers a how to on heat pump and Phoenix air conditioning preservation during severe winter weather.
Phoenix HVAC Preservation Tips – Dealing With Cold, Heat, Rain and Wind
Poorly maintained air conditioning systems are subject to unnecessary points of failure. Although crafted to withstand even extreme weather changes and conditions, HVAC systems perform better when homeowners follow basic air conditioning preservation practices. The following tips lead to increased longevity in both heat pumps and air conditioners.
1) AC Preservation – Avoid Covering Your System
Someone may consider a cover a sensible component of efficient Phoenix air conditioning preservation. This would be error. HVAC systems are designed to weather rain, snow and wind. Here are three reason covering an outdoor condensing system may actually damage the unit – even on a unit with a temporary disconnect from power:
HVAC & Accumulated Moisture… No cover will effectively keep moisture out of external air conditioning components. Evaporation draws water up from the ground. Humidity in the air penetrates any break in the seal of the cover. The splash of raindrops promotes moisture accumulation within the confines of the cover.
HVAC & Rodent Control… By nature, heat pumps and air condensing units are designed to deter rodents from finding sufficient cover for nesting. Don’t void this purpose by offering rats a nice, warm, cozy external HVAC system.
HVAC & Effective System Airflow… Air conditioning systems function by effective movement of air. A cover can hinder the system to the point of critical breakdown. An even minor obstruction to AC airflow can increase accumulation of mildew and mold.
2) AC Preservation – Powering Down When The Power Goes Down
Bad weather sometimes causes a local outage of power. Problems during repair of the lines can cause multiple power surges to enter your home. If severe weather causes your household power to go out, you might consider tripping the main HVAC fuses until after the problem is fully resolved.
3) AC Preservation – Batting Down For High Winds
Just as installing a cover can damage the exterior components of your heat pump or air conditioning condensing unit, so can wind blown debris. Be prepared for high winds. Keep yard furniture, toys and brush secured, stored, or effectively distant from your HVAC system.

Survey 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:

A Homeowner’s Guide To Troubleshooting A/C Equipment Prior To Calling The Repairman
Sometimes even a reliable HVAC service contract through the very best HVAC maintenance firm fails to prevent the need for a bit of rushed homeowner-handled air conditioning troubleshooting. Facts are simple: A well-serviced home A/C system typically runs without a great deal of unexpected complications.
However… Simple accidents and minor process failures do occasionally demand attention.
When you call a quality well-staffed HVAC service center you expect a rapid and often same day response to your home heating or cooling problems. Yet quick service does not always ensure that you will not lose a few hours of work time, or vacation time, or perhaps miss a baseball game you promised to attend.
Thankfully, some of the basic functional problems associated with your typical ducted split-type home air conditioning system can be corrected in record time by you the homeowner. The following tips are not designed to replace scheduled routine HVAC maintenance and service processes. However, this guide will help you check for a quick solution in a tough home cooling or heating situation.
It’s not about trying to save the cost of calling in an A/C repairman. It’s just about avoiding loss time when the problem could be handled by a bit of basic air conditioning troubleshooting.
** Note **
The following tips are not all-inclusive. Furthermore, we make no effort to evaluate your knack for performing A/C troubleshooting processes. If you do not understand the steps involved in a given process, call someone better qualified for the job.
5-Step Simple Air Conditioning Troubleshooting
1) HVAC System Not Cooling
Confirm that the thermostat/controller temperature setting reflects your cooling expectations and that the unit is set to cooling rather than heating or off.
Check and if necessary reset the main HVAC breaker in your home circuit breaker box. Also check the breaker that is typically located near to modern A/C condensing and heating units.
Visually confirm that both the indoor air handler and the outdoor condensing units are physically running.
Visually confirm that the outdoor condensing unit is not frozen over with ice.
Disengage the main HVAC breaker at your home circuit breaker box. Wait at least one hour before restarting. This may force the system to reset itself.
2) Limited or Nonexistent System Airflow
Ensure that all air filters used in any of your HVAC system components are clean. Replace if necessary. If your system is under an A/C maintenance contract, report the issue to the service provider. You may need to install a better grade of filter or isolate the cause for excess dust in your home.
Visually examine any external or internal units for signs of water accumulation in, near or own the exterior or indoor coil enclosure. Ice accumulation on the external Air Conditioning condensing unit is easily to spot. On the inside unit, be it in the attic, basement or crawlspace, hand test for an excessively cold exterior surface.
3) Overflow From the Indoor Air Handler Drain Pan
Remove any clogs blocking the exhaust pipe on the drain pan (See illustration). If there are not in the exhaust pipe, this homeowner-handled air conditioning troubleshooting secession should be promoted to the professionals. In the mean time, protect your floors and attic by turning the system off.
4) Compressor Fails But Fan Runs or Compressor Starts But Fan Fails
If the compressor fails to start, there is not much the average homeowner can do. The problem can relate to a bad compressor or merely a system that is low on refrigerant. To fix, call your local HVAC service center.
If the condenser fan fails to turn but the compressor starts, the problem may reside in the condenser fan motor. This repair is also beyond the scope of the average homeowner. Call in the pros.
5) Great AirFlow But Poor Cooling
Measure the temperature difference between the air leaving the air handler and the air entering the air handler. Modern high efficiency air conditioning systems typically run with a near 15-degree drop. Older units may show as much as 18 to 20 degrees difference.
Temperature drops that are below the norm indicate that your system is low on refrigerant. Call in a local HVAC service tech to correct the problem.
Temperature drops that greatly exceed the door indicate that the system is suffering a problem with the airflow system. Clean or replace the air filter. If that does not resolve the problem, ensure that the evaporator coils are clean. It that too fails to resolve the problem, clean the blower wheel.
Possible causes also include improper system design and/or installation, an incorrectly sized duct system, or simply a failure to perform routine HVAC maintenance.
