Arizona Air Conditioning Only One Component in Monsoon Safety Considerations

The Phoenix based American Cooling and Heating Website site is more than a mere sales tool to a for-profit Arizona Air Conditioning service center. The company strives to provide pertinent information relevant to current Valley Metro residents and businesses.

Dealing with the severity of Arizona weather phenomenon requires awareness of the total issue and not merely those components that are associated with Phoenix AC repairs. The following Monsoon safety tips will help you protect your family during the current Arizona Monsoon season.

Dust Storms

Linked to Microbursts, dust storms (haboobs) can kill. Never drive in a haboob. There are no reduced visibility options. If you get caught in a dust storm: 

  • Park the vehicle off the road
  • Turn off your headlights
  • Leave the vehicle in park and avoid putting your foot on the brake pedal.
  • Stay in the vehicle.
  • Do not move until the storm is passed. 

Flash Flooding

Understand the danger of moving water. Flash floods rank as the number one thunderstorm-associated killer. More often than not, the deaths occur in vehicles. Even water depths less than two feet can carry your truck or car into disaster. When flash flood warnings are in effect: 

  • Avoid entering moving water.
  • Keep close watch over young children. During thunderstorms, it only takes moments for a creek or a wash to turn deadly.
  • When traveling at night, avoid roads that are known for flooding. Darkness hinders your ability to judge water depth and road conditions. 

Wind – The Microbursts

Thunderstorms often produce sudden thrusts of downward air gusts, commonly called “downburst winds,” but technically identified as Microbursts. The force of a Microburst can exceed 100 mph. The danger to person and property is sudden, extensive and possibly deadly. Clouds of ground level dust may accompany the Microburst.

For safety during Monsoon thunderstorms: 

  • Get inside a sturdy structure
  • Avoid windows and glass doors
  • Use a battery operated radio to keep track of current news. 


According to the Arizona Division of Public Health Services (DPHS), heat related fatalities in the area are on the rise. In 2011, 206 U.S. citizens died as a result of extreme heat. This is 68 more heat related deaths than what occurred in 2010, and it is almost double the preceding ten year average.

The Arizona DPHS describes AZ heat as “more than a nuisance – it is lethal.” Authorities define heat as the nation’s number one weather-related killer. Recognize the threat and take appropriate defensive actions.

Here is how to survive the intense Arizona Monsoon temperatures: 

  • Restrict outdoor projects to the cooler hours of the day either mornings or evenings
  • Wear clothing suitable for extreme heat conditions
  • Take breaks, often and then more often
  • Take advantage of any nearby Air Conditioned structures
  • Drink water, in excess of all that you think you need
  • Keep an eye on the elderly, the young and people with known health conditions
  • Never leave children, pets or any other living creature in a vehicle that lacks adequate ventilation and/or functional air conditioning.
  • If you or someone with you experiences heat stroke — Call for emergency assistance.

The Definition of a Fully Equipped Gilbert Air Conditioning Service Center

Summer temperatures in Arizona place high demands on Gilbert AC repair techs and Gilbert AC service centers. For long periods of time, typical heat indexes can hit and linger in the triple digit range. The city merges big city conveniences into the core of stunning desert terrain known for attracting the attention of people with a mind to be in open spaces.

Gilbert is a good place. The city has class and a sense of character that distinguishes it from other U.S. towns and cities. Yet the harshness of the landscape can lay a heavy toll upon the rugged lovers of the desert lifestyle. Long months of 100-plus degree summer temperatures can be dangerous to even the most rugged Gilbert homeowner.

Making contact with a professional Gilbert AC service center can be one of the most important decisions a Gilbert desert dweller ever makes. 


A Division in Quality

Not all Gilbert AC repair techs practice the same principles and not all Gilbert AC service centers provide the same quality of service. Shortcomings in customer service and tech performance can be due to:

  • A company’s inability to keep up with the seasonal workload
  • Insufficient training of the available personnel
  • Insufficient tech-power
  • Overworked vehicles
  • Limited financial resources
  • And many other complications.

No business owner strives to fail, but sometimes companies are forced to operate beneath peek efficiency levels. The Arizona summer is never a time for an AC service center to be short handed or service-equipment hampered. Yet some Gilbert Air Conditioning Service Centers are willing to risk the consequences of reduced personnel and reduced spending on the maintenance of service vehicles.

Being small in size can enable a local AC repair company to offer better upfront prices than what can be obtained via a fully equipped Gilbert Air Conditioning Service Center. But the question remains: Can an understaffed and ill-equipped Gilbert AC Repair Shop provide:

  • Guaranteed 24-hour turnaround
  • Expert heating and cooling technicians with experience in Carrier, Goodman, Rheem, Trane and others
  • Quality customer service
  • A complete line of component parts for Amana, Carrier, Goodman, Rheem, Trane or any other top heating and cooling products
  • Drug free tested technicians
  • A history of being in the same business year after year
  • Or the assurance that the AC installer will be around to keep up with customer warranties?


Arizona-Based American Cooling and Heating, a Fully Equipped Gilbert AC Service Center

Every Gilbert AC Repair Center understands the health risks associated with a broken or poorly functional home or business cooling system. American Cooling and Heating knows the value of quick response service calls. They don’t come up short handed on technicians and they don’t come up shy of cooling components or equipment.

In towns and cities where personal comforts are the only criteria for installed air conditioning, late arrival repair techs and delayed component shipments may be questionable but acceptable air conditioning “solution”. In Gilbert AZ, such poor response can result in serious health issues.

Getting technicians to the worksite on time is part of doing the job right. Having on-hand components for Carrier, Goodman, Rheem, Trane and other top HVAC equipment is also part of doing the job right. But technical know-how and skill, professional onsite behavior and quality customer service make the finishing touches.

The AC techs at American Cooling and Heating are:

  • Gilbert AC Installation and AC Repair professionals
  • Trained in all matters pertaining to the American Cooling and Heating assurance of reliable customer service
  • Instructed in the factory specified features of repair and installation for Carrier air conditioning equipment, Trane heating and cooling units, Goodman AC equipment and every other top heating and cooling product on the market
  • Certified as one of the most skilled air conditioning technicians in Gilbert Arizona.


Service Center or Fully Equipped Service Center – Which Suits Gilbert Residents Best?

Even the best Do-It-Yourself homeowners get very careful when buying or installing air conditioning equipment. Without the right training and tools, installing an AC can end up wrong in many ways. Saving a few dollars on the front end can result in major expenses at the tail end.

Cheap repairs and AC installations can end up carrying a heavy price tag. To get the best for the least cost includes hiring a Gilbert AC repair center that does the job right on the first go-round. Some Gilbert residents and even some Gilbert businesses may opt to go with an under financed and short staffed repair center. The wise ones, even the DIY masters, tend to stick with a fully equipped Gilbert AC Service Center.

Understanding Your Phoenix Air Conditioning System: AC Condenser Coils the Function and Purpose

Internal View of AC, including Condenser CoilsThe quality, design and effectiveness of your Phoenix AC Condenser coil play a critical role in your battle against the extremes of Arizona temperature shifts. Efficient heating and cooling of your home involves much more than merely selecting a heat pump, an AC or a split system. To create a complete and efficient Air Conditioning system, your Phoenix AC installer must select and match your condenser to the appropriate sub-components.

But what makes Air Conditioning Condenser Coils so critical to the function of the system? Consider the following three principles of AC mechanics and operation: 

  • The system compressor pushes pressurized gas through the AC Condenser Coils
  • The condenser converts the gas to liquid
  • The process is based upon the principle of heat transference wherein heat always tends to shift toward the cooler of two or more materials or substances. 

Your AC condenser coils are designed to transfer heat into the air that passes over the coils. As the transfer process takes place, the gas in the coils condenses. However, the molecular structure of AC Refrigerants varies by type. Condensers used with R-12, R-134 and R410A systems are not interchangeable. Upgrading your Phoenix AC unit to a different refrigerant system is complex and expensive.  

For more details on problems associated with older refrigerants, check the May 1st American Cooling and Heating article on the Montreal Protocol.


What Happens Inside the Unit 

As your home AC compressor increases the pressure against the refrigerant, a strange process occurs: Heat within the system begins to accumulate into a single region of the unit. The temperature of the refrigerant begins to exceed the ambient temperature of the air cycling across the condenser coils. Clogged fins hinder the function of the condenser. Your home or business AC begins to perform with less efficiency and may even freeze the coils. If your system seems sluggish or sometimes freezes up, contact the AC&H Phoenix AC Repair center. Our full-service heating and cooling maintenance and tune-up program leaves no condenser fin un-check.


High Condenser Pressure Opposed to Low Condenser Pressure

Some Gilbert AC Service techs may add too much oil to your air conditioning system. This results in flooding wherein your condenser unit develops high head. This hinders the evaporator process of your Mesa Air Conditioning system. Cooling becomes less and less efficient.

Here are some the indications of AC troubles and the associated causes: 

  • Too-High Condenser Pressure – Typically evidenced by excessive head pressure on the high side of the gauge. Caused by hindered or reduced airflow over the condenser coils or restricted refrigerant flow in the high side of the system.
  • Too-Low Condenser Pressure – A reversed situation wherein the pressure on the low side gauge exceed normal expectations. Typically involves reduced heat exchange in the AC Condenser, which permits excessive heat to remain in the system’s low side. Can be caused by a filed compressor piston or reed valve.


Copper Versus Aluminum Condenser Coils 

This is an ongoing argument. AC systems with aluminum condenser coils typically cost less than systems with copper condenser coils. However, some techs argue that copper condenser coils are stronger and more durable than aluminum condenser coils. Issues concerning corrosion, weight and system expense are also components of the arguments. The May 9 AC&H article compares aluminum condensing coils against copper condensing coils. Perhaps it will help you better understand the reasoning behind these component battles. 

American Cooling and Heating provides Phoenix AC Installation and Repair throughout the greater Metro Valley area, including Mesa, Gilbert, Scottsdale and other communities. If you have questions or need help, call us now. Our 24-hour response team is ready and able to provide honest and accurate guidance on all matters pertaining to home or business AC installation or services.

AC Components – Evaporator Coils and How They Function In Air Conditioning Equipment

Carrier Air Handler and Evaporator CoilAir Conditioning Evaporator Coils – Tips From the AC&H Phoenix AC Installation Service Center

Central air conditioners contain two major cooling components: The Condenser coil and the Evaporator Coil. In the typical system, the condenser is located outside the home or office building. However, the Evaporator coil is normally associated with the furnace component of the air conditioning unit. It is mounted in the junction of the main internal duct system.

Keeping your Mesa or Scottsdale AC system clean and efficient requires yearly inspection and routine maintenance of the functional components, including the condenser and the evaporator coil. Many of the advertised discount HVAC tune-up offers ignore the condition of your evaporator coil. If your current AC inspector and AC tune-up provider fails to open the internal unit, you can bet that they have ignored the importance of a clean evaporator coil.

Ensure that your next Phoenix AC maintenance is performed by a licensed, insured and certified Phoenix air conditioning service center. Contact American Cooling and Heating to schedule a complete AC maintenance service call.

Evaporator Coils and the Split System

The typical central AC system operates as a split system. Thus the unit contains a “hot” side and a “cold” side. The “hot” side is positioned exterior to the home. The “cold” side is in the crawlspace, the attic or sometimes in an internal closet compartment. Core components within each unit section are as follows: 

  • Hot Side – Typically contains the condensing coil, the fan and the compressor, as well as various electrical switches and capacitors
  • Cold Side – Usually consist of a cold coil and an expansion valve, typically assembled as a sub-section of your air handler or furnace system. Home cooling occurs when the air handler forces air through the evaporator coils and then delivers that chilled air throughout your home duct system.

Evaporator Coils – The Process of Home Cooling in Action

Evaporators come in three general configurations: Cased, Uncased and Vertical. Correctly matching the evaporator coil to the specifications of your exact AC unit determines the efficiency and performance of the system. The condenser pipes, evaporator pipes, system ductwork and air handler work together to maximize and evenly distribute the cool air transfer of air throughout your home.

As air from the air handler or furnace passes over the pipes that make up the evaporator coil, heat is absorbed into the pipes. Cooled air is then delivered into the ducting system and distributed throughout the house. Refrigerant within the coils is returned to the external compressor, and then the process starts over again.

Assuming that all systems are evenly matched and working efficiency, the evaporator coil is kept slightly under the dew point but moderately cool. This causes it to condense water vapor from the processed air. The moisture is drained from the system. The cooled area of the home experiences a lower level of humidity.

For further information, read the AC&H detailed heating and cooling glossary.

Phoenix AC Service and Maintenance

Routine system check-ups and maintenance preserve the life of your Mesa air conditioning equipment. Evaporator coils can age, rust or wear down. Proactive system maintenance and upkeep of your Gilbert AC system assures you of efficient system performance, long-term reduction in your energy bill and increased durability of your Phoenix air conditioning equipment.

Homeowners can perform many of the basic heating and cooling maintenance procedures. However, cleaning your evaporator unit and your evaporator coils can result in a damaged system. Don’t make this a do-it-yourself solution without studying the process via a certified training manual.

Aluminum Condensing Coils Vs. Copper Condensing Coils: Advise From Phoenix AC Installation Pros

For the Phoenix AC installation industry, the debate concerning aluminum condensing coils versus copper condensing coils could be termed “economic focused.” For the Mesa homeowner, the Scottsdale business owner or any other buyer in need of new air conditioning equipment, the debate hinges on how to get the best quality for the least expenditure.

A Note of Qualification For Arizona Air Conditioning Contractors

If you are a Phoenix air conditioning service center, don’t let the “economics” comment ruffle your feathers. This article comes in via the viewpoint of a buyer. Industry arguments about copper versus aluminum involve many aspects of technology. From the viewpoint of an Arizona AC contractor, economics is only one component of the debate. However, from the viewpoint of the buyer, all contractors have a primarily sales-orientated end goal.

Buyers expect heating and cooling installation and repair dealers to hedge the details. It’s a mindset that comes about due to the competition in the HVAC industry. The pricing, the product favoritism and the value-added sales incentives merely reflect the mindset of new and used car dealers.       

Dedicated To Meet The Needs of Inquiring Valley Metro Homeowners

This article is for the benefit of homeowners and business owners throughout the greater Phoenix, Arizona metropolitan area. As such, the text presents both sides of the argument: Which works best, air conditioning with aluminum condensing coils or air conditioning with copper condensing coils.

Even the information presented via governmental and educational resources tend to be tinted by manufacturer economics. Everyone wants to claim the better heating and cooling solution. It’s just a matter of how to gain marketing share.

Here at American Cooling and Heating we carry all major brands of heating and cooling equipment, including Amana, Carrier and Trane. We handle units that are crafted with copper condensing coils and units manufactured with aluminum condensing coils. Economics may indeed be our purpose for being in business. Without profit, we would fade away.

However, AC&H strives to meet any customer need or demand. Perhaps the following information will help simplify your choice.

Aluminum Condenser Coils – The Beginning

It began in the 1970s when General Electric was still in the HVAC business. All other AC manufacturers provided condensing units with aluminum fins bonded to copper tube. GE wanted to reduce production expenses. This brought about the introduction of coils with aluminum tube and aluminum fins.

For the most part, this was an industrial solution. Prior to 1980, only around 20% of residential structures had installed air conditioning. AC unit components and AC installation expenses rendered air conditioning as a luxury item. Very few homeowners could afford central heating and cooling.

Then the market shifted. Construction boomed. Inflation invaded. Home values increased and the market for home air conditioning bloomed into a lucrative enterprise.

The use of aluminum coils provided GE with a competitive edge. In no long time, other AC manufacturers began to produce their own version of compatible aluminum coil solutions. GE no longer competes in the HVAC business, but the aluminum tube with aluminum fin condensing coil remains a stable market product.

Drawbacks of Using Aluminum AC Coils

The arguments in this matter fall on both sides of the street. Some of the reasoning can be demonstrated scientifically. Some of the reasoning is merely personal dealer favoritism. From a scientific viewpoint, the following statements are true – providing that all tubing measurements are identical between the components:

  • Copper is superior in strength to aluminum
  • Copper is more reliable than aluminum
  • Copper is more durable than aluminum
  • Copper is easier to maintain than aluminum
  • Copper provides better heat transfer characteristics than aluminum
  • Aluminum coils damage easier than copper coils
  • Aluminum coils are more difficult to clean than copper coils.

However, due to the expense of manufacture and an effort to keep up with the reduced unit pricing associated with units that use aluminum tube coils, the manufacturers of copper-based coil systems have resorted to downsizing the thickness of the copper tubing wall. Thus strength, reliability and durability are relative to the actual components used during the air conditioning construction stage.

Field Maintenance is also often listed as another drawback associated with aluminum tube condensing coils. Some Phoenix AC repair companies complain that leaks in aluminum tubes are more difficult to fix than leaks in copper tubes. The argument contends that aluminum coils cannot be repaired in the field. To the homeowner, this means more downtime. To the AC service center, this means additional expenses when dealing with warranty issues.

Unfortunately, the DOE does not provide statistics pertaining to leaky air conditioning coils – aluminum or copper. The rule is simple: If your unit is low on refrigerant, have trained AC technicians repair the leak, test the repair and then recharge the unit to manufacturer recommendations.

Galvanic Action describes leaks that occur when oxygen reaches the condensing coil at the point where the aluminum meets the copper in the condensing unit. The problem is often considered not repairable. Qualifier: More and more AC repair centers now carry welding rigs capable of welding aluminum. Over the years, the aluminum coil repair process has improved and will likely continue to improve in the future.

Drawbacks of Using Copper AC Condensing Coils

In the earlier years of aluminum condensing coils, Arizona AC contractors tended to favor copper tube with fin coils. However, a change over may be taking place. No matter what other arguments are in place, unit cost remains a primary factor in any AC purchase decision. For example:

  • Aluminum coils cost less to manufacture than copper coils
  • Due to pliability, copper coils require more material than aluminum coils (even as much as three times the material); this results in higher manufacturing expenses
  • Galvanic corrosion is common problem with all copper tubing
  • To remain price competitive, new units are shipping with substandard quality coils
  • The thinner the copper, the more difficult it is to repair the coil.

Copper is harder to damage than aluminum, provides better heat transfer and is easier to clean. Modern engineering eliminates the majority of galvanic corrosion. The prices of the units continue to remain considerably higher than AC equipment constructed with aluminum condensing coils. Homeowners question the value of the exchange.


Without collected statistics, fears of leakage and early system failure are difficult to substantiate. All-aluminum coils are more fragile than copper tube coils but manufacturers take care of this issue by protecting the units inside a heavy-duty cabinet. This, of course, results in a system that is harder to clean and maintain.

When area consumers call for AC services and semi-annual system tune-ups, they get often get ripped by vendors who provide a less than necessary clean and inspection process. Most Phoenix AC installation and repair centers do not properly clean the coils.

American Cooling and Heating goes the extra mile. Our Full System AC Maintenance Service includes opening the case, applying special cleaning fluids to the coils and many other value-added AC tune-up functions. If your system is leaking, contact us today. If you need to install new air conditioning in your home, we service Mesa, Gilbert, Scottsdale and most all other Phoenix area homes and businesses.
