10 Tips to Prepare Your AC Unit for Arizona’s Monsoon Season

Living in the Sonoran Desert presents unique challenges for Phoenix homeowners, especially during our monsoon season. This season, characterized by a shift in wind patterns, brings moisture from the Gulf of California and the Pacific Ocean into the region. 

As a result, there is increased humidity, thunderstorms, heavy rainfall, and occasional flash floods. While the monsoon season is crucial for replenishing water supplies and supporting local ecosystems, it also brings risks, such as severe weather events and flooding.

During this time, thunderstorms can produce strong winds, often leading to dust storms or “haboobs.”

These dust storms can worsen allergies and respiratory conditions while negatively affecting home systems, making them a notable concern for your air conditioning (AC) unit during the monsoon season.

Proper preparation and maintenance can ensure your AC unit functions efficiently, providing comfort, healthy air circulation, and preventing unexpected breakdowns. 

Here are some essential tips the expert air conditioning technicians at Desert Diamond Air have drawn up to help you prepare your AC unit for the monsoon season, especially for those new to the Phoenix area and monsoon seasons in general.

How to Prepare Your AC Unit During Phoenix’s Monsoon Season

Preventative maintenance is key to preparing your HVAC system for monsoon thunderstorms and haboobs. These steps will help protect one of your Phoenix home’s most significant investments while ensuring your home remains safe and indoor air quality remains healthy. 

1. Clean or Replace Air Filters More Frequently

During the monsoon season, air filters can quickly become clogged with dust and debris. A dirty air filter may show that dust and debris are being removed from your air, but it can restrict airflow, reduce the efficiency of your AC unit, and lead to higher energy bills. 

Before the monsoon season begins, check your air filters and clean or replace them if necessary. You should usually check again in a few months, but more frequent checks are needed during periods of heavy dust storms.

If your air filter needs to be cleaned, change it even if it is ahead of its regular schedule. 

2. Inspect and Clean the Outdoor Unit Before and After Storms

Your AC’s outdoor unit is exposed to the elements and is particularly vulnerable during the monsoon season. Dust and debris can accumulate on the condenser coils, reducing the unit’s efficiency and potentially causing it to overheat. 

Before the rains start, inspect the outdoor unit and remove any debris around it. Additionally, trim any vegetation around the unit to maintain proper airflow.

After a dust storm, use a garden hose to wash off the dust from the coils gently, but ensure the unit is turned off before cleaning.

3. Check for Any Leaks or Blockages in Your Drain Line

Humidity levels rise significantly during the monsoon season, increasing the risk of condensation and water leaks in your AC unit. Inspect the drain lines and drip pans for any blockages or leaks.

A blocked drain line can cause water to back up and overflow, potentially damaging your AC unit and home. Use a wet-dry vacuum or a plumber’s snake to clear any blockages from the AC drain line, and ensure the drip pan is clean and positioned correctly.

4. Ensure Proper Insulation Around Ductwork

Proper insulation around your AC unit and ductwork is crucial for maintaining efficiency during the monsoon season. Insulation helps prevent condensation from forming on the ducts, which can lead to water damage and mold growth. 

Have the insulation inspected for signs of wear and tear and replaced if necessary. Sealing gaps or cracks around windows and doors can also help keep the cool air inside and humid air outside.

5. Schedule a Professional HVAC Maintenance Check

One of the best ways to prepare your AC unit for the monsoon season is to schedule a professional maintenance check. 

A certified HVAC technician from Desert Diamond Air can thoroughly inspect your unit, clean the components, and make necessary repairs.

Regular maintenance can help identify potential issues before they become major problems and ensure your AC unit operates at peak efficiency throughout the season.

6. Install a Surge Protector for Your Air Conditioner

Monsoon season often brings thunderstorms, which can cause power surges. These surges can damage your AC unit’s electrical components, leading to costly repairs. Installing a surge protector can safeguard your unit from these power fluctuations. 

Consult with a Desert Diamond Air HVAC professional to determine the best type of surge protector for your AC unit.

7. Adjust Your Thermostat Settings

During the monsoon season, the air is cooler but more humid. Adjusting your thermostat settings can help maintain a comfortable indoor environment while reducing the strain on your AC unit. 

Setting the thermostat a few degrees higher than usual can help balance the humidity and temperature, making your home comfortable and reducing energy consumption.

8. Use a Dehumidifier to Reduce AC Workload

High humidity levels are expected during monsoon season, and it can also rise indoors when humidity is high outdoors. This can make your home feel warmer and more uncomfortable.

Using a dehumidifier in conjunction with your AC unit can help remove excess moisture from the air, improving indoor air quality and comfort.

9. Seal and Weatherproof Your Home

Monsoon season can bring heavy rains and strong winds, leading to water infiltration and increased humidity inside your home. Sealing and weatherproofing your home can keep the indoor environment comfortable and reduce the workload on your AC unit.

Check for cracks or gaps in the walls, windows, and doors, and seal them with weatherstripping or caulk.

10. Monitor and Repair Your AC as Needed

Monitor your AC unit’s performance throughout the monsoon season and observe for any unusual noises, odors, or decreased cooling efficiency. If you notice any issues, contact Desert Diamond Air to address them promptly to prevent further damage.
