🌱 2️⃣ Seasonal Maintenance — What Savvy Does Each Season

Think of your R-32 system like a car. It needs regular check-ups to keep it running smoothly, and by spreading out maintenance throughout the year, you’ll catch small issues before they become big problems.

🌷 Spring Maintenance (Start Fresh)

Spring is the perfect time to give your AC a good “spring cleaning” and prepare it for the summer heat.

What to Do:

Change/clean filters: I replace or wash my filters every 60–90 days, depending on usage. Dirty filters can restrict airflow, causing the system to work harder and wasting energy.
Clean condenser coils: Over the winter, your unit likely accumulated dust, leaves, and debris. Cleaning the condenser coils is essential to ensure proper heat exchange and airflow. Use a soft brush or vacuum cleaner to remove debris.
Inspect refrigerant levels: Low refrigerant means your system is working overtime to cool your home. While technicians should handle refills, it’s a good idea to have them check the levels during an annual check-up.
Inspect system operation: Run the system briefly to listen for any unusual sounds or vibrations. If you hear odd noises, it could signal loose components or mechanical issues.

Savvy Tip: Cleaning your filters and coils in the spring prevents overworking your system during peak summer months when it will be running the most.

🌞 Summer Maintenance (Peak Performance)

The summer months are when your R-32 system works its hardest. By performing a few key maintenance tasks, you’ll ensure it stays efficient and cools your home effectively.

What to Do:

Check refrigerant levels: Summer heat can cause refrigerant levels to drop, so it’s important to check the levels once every season. Low refrigerant can strain the compressor and reduce cooling efficiency.
Inspect airflow and ductwork: Ensure that your system has unobstructed airflow by inspecting your ducts and vents. If your system is struggling to cool certain rooms, check for leaks or blockages in the ductwork.
Clean the drip pan and drain line: Clogged condensate lines can lead to water damage or mold growth. Clean the drain pan and ensure the drain line is clear of debris. If it’s clogged, use a wet/dry vacuum to clear the line.
Check the thermostat: Make sure your thermostat is set to the correct temperature and is reading accurately. Sometimes, extreme heat can affect how well the thermostat controls the temperature.

Savvy Tip: Regular airflow checks and refrigerant monitoring in the summer prevent system strain, keeping your bills low while ensuring consistent cooling.

🍂 Fall Maintenance (Pre-Winter Check-Up)

Before the cold weather sets in, fall is a good time to prepare your system for winter months and ensure it continues to run smoothly during the transition.

What to Do:

Replace or clean filters: Replace filters if they’re too clogged or dirty from summer use. Cleanable filters should be washed thoroughly before winter.
Inspect insulation: Make sure your home’s insulation is in good condition to minimize heat loss in winter. This also reduces the workload on your HVAC system.
Check the thermostat settings: I always recheck my thermostat settings for heating (if using a heat pump) to make sure it’s working properly.
Clear debris: Remove leaves and debris around the outdoor unit. If your system is on the roof, ensure no leaves or branches have accumulated on top of the unit.

Savvy Tip: Clean ducts and replace filters in fall so your system doesn’t work harder in winter. This prevents unnecessary wear and tear.

❄️ Winter Maintenance (Prepare for the Cold)

Winter might not be the time to use your R-32 system, but it’s still important to keep it in tip-top shape for when you need it again.

What to Do:

Shut off power: If you live in an area with harsh winters and you’re not using your air conditioner, it’s a good idea to shut off power to the system. This helps prevent electrical issues and protects the unit from extreme weather conditions.
Protect from snow or ice: If your unit is outdoor mounted, cover it with a weatherproof tarp or debris cover to protect it from snow, ice, or falling branches.
Schedule a professional check-up: Schedule your annual professional maintenance in winter when the system isn’t in use. A technician can clean the internal parts, check refrigerant levels, inspect components, and ensure everything is ready for the next cooling season.

Savvy Tip: Protecting your unit from snow and ice helps prevent long-term damage. A little winter protection goes a long way.

🔧 3️⃣ Filter Care & Airflow Maintenance

Air filters are an essential part of your R-32 system. Keeping them clean is one of the simplest (yet most effective) tasks you can do to extend the life of your AC.

🌬️ Why Airflow Matters

Your system depends on unobstructed airflow to function properly. Air filters trap dust, dirt, and debris to keep the system running smoothly. If the filters get clogged, airflow is restricted, which forces the system to work harder and consume more energy.

🧹 How to Clean or Replace Filters

For disposable filters: Replace them every 60–90 days (depending on usage and filter type).
For washable filters: Clean them by washing with mild soap and warm water. Dry thoroughly before reinstalling.

🧴 Types of Filters

There are several types of filters to choose from:

Fiberglass filters (basic, inexpensive, but less effective)
Pleated filters (better at trapping dust and allergens)
HEPA filters (best for air quality and efficiency, especially for allergy sufferers)

Savvy Tip: If you have pets or live in a dusty area, opt for pleated or HEPA filters. They last longer and catch more particles, keeping your system running smoothly.

🧼 4️⃣ Cleaning the Coils — Keep Your System Efficient

Condenser and evaporator coils are where the magic happens in your R-32 AC system. Keeping these coils clean is essential for maintaining proper heat transfer and system efficiency.

🌞 Why Clean Coils Matter

Dirty coils can prevent the system from cooling effectively and force the compressor to overwork. This increases energy consumption and maintenance costs.

🧴 How to Clean Coils

Condenser Coils: Use a vacuum or soft brush to remove debris and dust from the outdoor unit’s condenser coils. Be gentle to avoid damaging the fins.
Evaporator Coils: Cleaning the evaporator coils once a year (usually in spring) ensures optimal performance. Use compressed air or a soft brush to remove dirt.

Savvy Tip: Cleaning coils twice a year can improve cooling efficiency by up to 30%. Plus, it helps prevent frosting and ice buildup.

🌡️ 5️⃣ Checking Refrigerant Levels — Why It Matters

Refrigerant is the lifeblood of your AC system. If levels are too low, your system won’t cool properly, and the compressor could get damaged. Keeping an eye on refrigerant levels is essential to maintaining system performance.

🌿 Why Low Refrigerant is a Problem

Low refrigerant levels cause your system to run inefficiently, resulting in higher energy bills and overworked components.

🧰 How to Monitor Refrigerant Levels

Refrigerant levels should always be checked by a professional HVAC technician. They’ll measure the pressure to ensure the levels are correct. If a system is low, the technician can recharge it and look for leaks.

Savvy Tip: Never attempt to refill refrigerant yourself. It’s best left to certified technicians to avoid leaks and environmental damage.

🧽 6️⃣ Cleaning the Drip Pan & Drain Line — Prevent Water Damage

One area that many homeowners overlook is the drip pan and condensate drain line, which are responsible for carrying away moisture collected during the cooling process.

💧 Why It’s Important

If your drain line is clogged, it can cause water damage or even mold growth. Regularly cleaning the drip pan and ensuring the drain line is clear will protect your system from unnecessary wear.

🧴 How to Clean the Drip Pan and Drain Line

Drip Pan: Wipe the pan clean to remove any standing water and debris.
Drain Line: Use a wet/dry vacuum to clear out the drain line. Alternatively, pour a mixture of distilled white vinegar down the drain to prevent mold buildup.

Savvy Tip: Check your drip pan and drain line every season to avoid standing water and the potential for mold or system damage.

🧰 7️⃣ Thermostat & Sensor Checks — Keeping Your System Running Smart

Your thermostat is the brain of your system, and ensuring it’s functioning correctly can save you money and keep you comfortable.

🌡️ Why Thermostat Accuracy Matters

If your thermostat is reading inaccurately, your AC system will be either overcooling or undercooling, which could lead to wasted energy and higher utility bills.

📱 How to Calibrate and Test Your Thermostat

Check the temperature differential between your thermostat and the actual room temperature. It should be within a couple of degrees.
Consider upgrading to a smart thermostat to improve efficiency, adjust temperatures based on your schedule, and monitor energy usage.
Test the sensor near the evaporator coil. It should sense air temperature correctly and not get blocked by debris.

Savvy Tip: A smart thermostat can save you up to 8% annually by automating temperature changes when you’re away or sleeping.

🔒 8️⃣ Preparing for Extreme Weather — Protect Your System

Your system needs protection from harsh weather conditions, especially if it’s installed outdoors.

🌨️ Protecting Your System from Snow & Ice

If your system is located outdoors, snow and ice can cause problems. Heavy snow can damage components, while ice buildup can block airflow.

💨 Protecting from Extreme Heat

Shading your unit from direct sunlight in the summer can help keep the system from working overtime.
