Why Are AC Units On The Roof In Arizona?

Rooftop AC units are commonplace in Arizona. This installation location is the result of optimal ventilation and circulation needs in such a hot environment.

Why Are AC Units Installed On Roofs In Arizona?

In the state of Arizona, it’s no secret that managing heat can be overwhelming at times. This means making sure your cooling system works properly is essential. When you have an AC unit for your house, the cooling system will be centralized. The system will be installed atop your home, routed directly through ductwork to the entire home.

Your home will ultimately benefit from this installation location because air can quickly circulate everywhere. Due to the routing of the air, cooler air will rise to the warmer air. The AC unit will then transfer warmer air from higher levels of the home into cooler air. The warm air does not need to be removed as efficiently since the cool air moves naturally from a rooftop system.

Rooftop units are economically-efficient for homeowners across the valley. You will be conserving more energy while ultimately saving money on the cooling system.

Rooftop AC Unit Benefits

What are the pros of installing an AC unit atop your roof? Let’s take a look below.

Less Maintenance

Rooftop units will not experience as much damaged as other outdoor units as they will be kept safe from frequent dust storms.

Theft Protection

Thieves will be unable to steal these units and take the valuable components found inside them.

More Yard Space

Putting the AC unit on your roof will free up more space in your yard.

Protection From The Elements

Beyond inclement weather, installing the unit on your roof means it can’t be damaged by normal chores like weed whacking and mowing.

How Long Do AC Units Last In Arizona?

The life of an AC unit can vary based on location, how well it has been maintained, and the specific model. Typically, these units will last between 15-20 years throughout the U.S. Due to higher temperatures, though, most AC units will last between 12-15 years in Arizona. Below are some key factors that can affect how long your AC unit lasts in the state of Arizona.

Environmental Conditions

Arizona’s climate is defined by scorching heat, with temperatures rising about 110°F during the summers. This extreme heat undoubtedly puts a lot of stress on AC units, causing them to work overtime. In addition, the dusty and arid desert environment can lead to increased wear and tear on the components, which impacts the AC’s lifespan.

AC Unit Size

For decades, Arizona homes featured AC units that were far too large for their cooling needs. This was known as “overtonning”, which was rampant at one point in time. An oversized or undersized AC unit will have to work harder than a unit that is sized properly for your home. Oversized units will cycle on and off more often than smaller units. Ultimately, this will lead to more frequent repairs.

Regular Maintenance

AC units need regular and frequent tune ups, just like cars. It is recommended to have your unit professionally serviced at least once per year. This will help to identify any potential issues before they become real problems. You do not want your unit to have to work even harder during the hot summer months.

Duct Cleaning

Your AC unit depends on a fully-functional and well-maintained ductwork. Regular duct cleaning is a necessity to prolonging your unit’s lifespan. Dirty ducts can shorten the AC’s lifespan and contribute to higher energy bills, overall.

Quality Of Installation

The initial quality of the installation of the unit can impact the lifespan significantly. However, improper installation can lead to reduced efficiency and premature wear. It is essential to hire qualified professionals to handle the installation.

Usage Patterns

Both the frequency and duration of the AC unit usage also affects longevity. Wear and tear will increase, especially during months of extreme heat in Arizona. Commercial establishments using AC around the clock will see their system have a shorter lifespan than residential units.
