What Temperature Should You Leave Your Arizona Home in the Summer?

What seasonal homeowners should consider before leaving their Arizona home.

The Landing Haven · Peoria, AZ

Before leaving Arizona for the summer, many seasonal homeowners ask the same question:

"What temperature should I leave my home while I am away?"

The answer is more complicated than it may seem. Temperature settings alone will not provide the peace of mind needed to meet the challenges of summer in Arizona.

There is no single thermostat setting that is right for every property. The goal is to keep the unoccupied home stable and protected without cooling it as though someone were still living there. Consistency is key and requires visible inspection and oversight using multiple senses.

A Higher Setting Still Requires Oversight

Many homeowners raise the thermostat before leaving to reduce energy use. Although increasing the temperature may be reasonable, the setting should be selected thoughtfully.

An older HVAC system may respond differently from a newer, more efficient unit. A home with large west-facing windows may hold more heat than one with better shade and insulation. Homes with multiple cooling zones may also require additional attention.

Before departure, it is recommended that an HVAC professional complete preventive maintenance and recommend the appropriate setting for your specific home and equipment.

It is also important to remember that choosing the right number is only one part of the process.

Air-conditioning issues can arise unexpectedly with the demands of monsoon season, humidity changes, and extreme heat. Control of cooling and humidity can be affected by a mechanical issue, power disruption, clogged drain line, thermostat problem, or tripped breaker.

Smart technology is helpful for seasonal and second-home owners, but it cannot explain what has changed or what may be causing an unusual reading. This is where the value of a professional home watch provider becomes clear.

What a Visible Home Watch Inspection Can Catch

A trusted home watch professional looks beyond the thermostat reading. They use sight, smell, sound, touch, and familiarity with the home to identify what a thermostat or sensor cannot fully express.

During a visible inspection, they may notice:

Visual

• A tripped breaker or blank thermostat screen
• Closed interior doors limiting airflow
• Water near an air handler, drain line, ceiling, or baseboard
• Window coverings left open and increasing heat exposure
• Condensation, staining, or discoloration around vents

Smell

• A musty odor or other change that may signal moisture or system trouble
• Food spoilage or odors caused by inconsistent temperature control

Sound

• Unusual sounds coming from the HVAC system
• No sound or airflow coming from the vents
• A refrigerator, freezer, or other appliance cycling unusually

Touch and Feeling

• Weak or uneven airflow from vents
• One room feeling warmer than the rest of the home
• A thermostat reading that does not match how the home actually feels

The Home Watch Sense

• The subtle cues and combined findings that may point to a potential or existing risk
• The familiarity developed through repeat inspections that allows a professional to look beyond the obvious

These are the kinds of details a remote sensor or camera may not reveal.

A smart thermostat can tell you that the temperature is rising, but a visible inspection can help determine what is happening inside the home and whether a qualified professional needs to be contacted.

Stability Matters More Than a Single Number

The most important question is not only:

"What temperature did you set before leaving?"

It is also:

"Is the home continuing to maintain that temperature?"

Arizona summer places steady demand on cooling systems. Regular home watch provides reassurance that the home remains stable and that visible concerns can be addressed before they have more time to develop.

Choose the thermostat setting with intention, prepare the HVAC system before departure, use remote monitoring when available, and arrange for a trusted local professional to confirm that the home continues to feel and function as it should.

The story of a home matters when considering its temperature. At The Landing Haven, we take pride in understanding and sharing that story through every inspection, with clear and thoughtful communication focused on prevention and peace of mind.

"Because the right temperature is more than a number on the wall. It is part of keeping your home cared for while you are away."
