Arizona Heating and Air Conditioning system maintenance importance.

Arizona has some of the highest temperatures in the United States. Phoenix, Arizona and the surrounding cities have temperatures in the summer months that have been above 120 degrees. Reference: (http://phoenix.about.com/cs/weather/a/weathertrivia_2.htm)
These temperatures have been known to cause deaths for people living in homes without working air conditioning systems. Reference: (http://ehp.niehs.nih.gov/1104625/)

The majority of homes built in Southwestern Arizona are built with a system to regulate the heating and cooling temperatures within the home. Most of these systems are commonly refereed to as just air conditioners or heating. There are actually several types of heating and cooling systems used, and they are vastly different in how they work. Most of these systems have similar parts that need to be maintained regularly.
The major parts of most heating and cooling systems are:



Evaporator – Receives refrigerant from the expansion valve
Condenser – Facilitates heat transfer
Expansion valve – regulates refrigerant flow into the evaporator
Compressor – A pump that pressurizes refrigerant


These parts manage refrigerant and move air in two directions, pulling air from the outside to the inside, and also pulling air from the inside to the outside of the coils. These systems also have several other parts that play vital roles in regulating air temperature. If one of these parts is not maintained regularly, the life of the system is drastically shortened, costly repairs needed to clean dirty coils, and replace broken down parts. An expansion valve is one of these parts; the expansion valve is located in between the coils to regulate the refrigerant going into the evaporator. The evaporator is the indoor coil that gets cold. When the refrigerant goes to the evaporator, the pressure of the refrigerant drops; this causes the refrigerant to change to gas due to low pressure. The Compressor is a pump that pressurizes the gas refrigerant back to a liquid.

Other parts to most heating and cooling systems are smaller in size and cost, but without them, the system will not function. These smaller parts are usually the parts that require maintenance to ensure the major system parts do not prematurely break down. A capacitor is one of these parts; the capacitor is what starts the motor, similar to how a battery starts a car. The fan is used to circulate the air. Air filters are used to help keep dirt out of the system. Coils are used for refrigerant flow.

Many Southwestern Arizona homes have heating and cooling systems on their homes as described above; some home require multiple systems to handle the square foot of the home. Heating and cooling systems come in all different sizes as well; the size is measured on by the air ton flow it produces. To have an average system on a home replaced in Phoenix Arizona, it involves having a heating and cooling HVAC EPA licensed professional expert to come to your home. The charge to have a single system replaced can vary from 4K in upwards of 10K, depending on location, type, seer rating, and other labor that may be involved with replacing the system. Systems that are not properly maintained can be expected to have system failure prematurely, causing the homeowner to incur high replacement costs.

Heating and cooling systems that are properly maintained, have the coils cleaned to allow full air flow into the unit by removing irritants know to stick to coils, capacitors checked for capacity percentage, refrigerant levels checked to ensure the proper amount is in your system for optimal performance, air filter changes to ensure proper air flow and eliminate irritants from entering the system. There are many other preventative processes that can are done by heating and cooling professional experts that prolong system life and performance.

The fee to have systems maintained is minimal, and seen as something not needed by some homeowners. Other homeowners are very dedicated to protecting the air system in their home, so they sign up for maintenance plans that ensure the system will be checked out at least twice a year. http://www.prosolutionsair.com/heating-and-cooling-preventative-maintenance/

A popular maintenance plan in Phoenix, AZ and the surrounding cities is called Aire Care. http://www.prosolutionsair.com/pricetable/elite-aire-care/ Many choose this particular heating and air conditioning maintenance plan simply because it is free. A popular company in Southwest Arizona is Pro Solutions Air. Pro Solutions Air introduced this maintenance plan in just June of 2013, and as of January 2014 there is already several hundred people who have signed up. This maintenance plan services all different varieties of heating and cooling systems, including larger commercial units called chillers. Reference: (Donald Wade, Owner Pro Solutions Air)


For smaller areas without central air conditioning there are systems called window units that are placed in the window, use up to 1 ton of air, cool areas up to 400 square feet; these systems need maintenance just like the larger systems to ensure optimal performance, longevity, and energy efficiency.


Central Air conditioning systems are more commonly used over window units because they are more efficient, and has air run through installed air ducts throughout the house, going into the various rooms in the home. throughout the home. There are two types of central air conditioning systems installed in homes, split systems or what’s called a package unit. A split system is used more over a package unit. The split system has a unit outside, and another part of the unit inside the home, hidden in a closet or attic most often. A package unit has just one unit piece, and is installed outside the home.

Both types of central air conditioning run at optimal performance when at proper capacity, refrigerant level, and maintained at least twice a year with an HVAC tuneup.
