As temperatures start to climb in Arizona, there’s one thing you absolutely must ensure is ready for the scorching heat: your air conditioning unit. With summers that can be brutal, making sure your AC is in top condition is essential for your comfort and well-being. Here are some tips to help you prepare your AC unit for Arizona’s summer heat.

1. Schedule a Professional Check-Up:

Before the heat of summer kicks in, it’s a good idea to have a professional HVAC technician inspect your air conditioning system. They can identify any potential issues and make sure your unit is running as efficiently as possible. This can help prevent breakdowns when you need your AC the most.

2. Clean or Replace Air Filters:

Dirty air filters can restrict airflow, making your AC unit work harder than it needs to. Make sure to clean or replace your air filters regularly, ideally every one to three months. This simple task can improve your AC unit’s efficiency and lifespan.

3. Clear Debris from Around the Outdoor Unit:

Leaves, dirt, and other debris can accumulate around your outdoor AC unit, obstructing airflow and reducing its efficiency. Make sure to clear any debris from around the unit and trim back any vegetation to allow for proper airflow.

4. Check and Clean the Condenser Coils:

Over time, dirt and debris can build up on the condenser coils, reducing their ability to dissipate heat. Periodically check the coils and clean them as needed. This can help your AC unit run more efficiently and keep your home cooler.

5. Inspect the Ductwork:

Leaky or damaged ductwork can lead to cooled air escaping before it reaches its intended destination. Inspect your ductwork for any signs of damage and have any issues repaired promptly. Sealing your ducts can improve your AC unit’s efficiency and reduce your energy bills.

6. Consider Installing a Programmable Thermostat:

A programmable thermostat allows you to adjust the temperature of your home automatically throughout the day, helping you save energy and money. Consider installing a programmable thermostat if you don’t already have one, and program it to raise the temperature when you’re away from home to save even more.

7. Schedule Regular Maintenance:

Finally, regular maintenance is key to keeping your AC unit running smoothly throughout the summer months. Consider signing up for a maintenance plan with a trusted HVAC company to ensure your system receives the care it needs.


Don’t wait until the heat of summer is in full swing to prepare your AC unit. By following these simple tips, you can ensure that your air conditioning system is ready to keep you cool and comfortable all summer long. From scheduling a professional check-up to cleaning and maintaining your unit, a little preparation now can go a long way in beating the Arizona heat.
