How To Clean Your Outside Ac Unit – A Comprehensive Guide – When summer comes around, we rely on our air conditioning units to keep us cool and comfortable. However, many people forget that the outside AC unit also needs some TLC. Neglecting to clean your outside AC unit can lead to reduced efficiency, higher energy bills, and even system failure. In this article, we’ll provide a step-by-step guide on how to clean your outside AC unit and keep it running smoothly.
Why Cleaning Your Outside AC Unit is Important
Your outside AC unit, also known as the condenser unit, plays a critical role in the cooling process. It’s responsible for releasing the heat that your AC system has absorbed from inside your home. The condenser unit contains a compressor, a fan, and a condenser coil. If any of these components become dirty or clogged, it can affect the performance of your AC system. Here are some reasons why cleaning your outside AC unit is important:
1. Increased Efficiency
A dirty condenser coil can reduce the efficiency of your AC system, causing it to work harder and use more energy. This can result in higher energy bills and more wear and tear on your system.
2. Longer Lifespan
Cleaning your outside AC unit regularly can extend its lifespan. Neglecting to clean it can cause the system to overwork, leading to premature failure.
3. Improved Air Quality
A dirty AC unit can circulate dust, dirt, and other allergens throughout your home. Cleaning it can improve the air quality in your home and reduce allergy symptoms.
Step-by-Step Guide to Cleaning Your Outside AC Unit
Now that you understand the importance of cleaning your outside AC unit, let’s dive into the steps you can take to keep it running smoothly.
Step 1: Turn Off the Power
Before you begin cleaning your outside AC unit, you need to turn off the power. This will prevent any accidents or injuries while you’re working on the system. You can turn off the power by flipping the circuit breaker that controls the AC unit or by using the on/off switch on the unit.
Step 2: Remove Debris
The next step is to remove any debris that has accumulated around the outside AC unit. This could include leaves, grass clippings, sticks, or other outdoor debris. Use a rake or broom to sweep away any loose debris, and then use a vacuum cleaner or a shop vac to remove any stubborn dirt or debris.
Step 3: Clean the Fins
The fins on your AC unit are the thin, metallic blades that surround the unit. They’re responsible for dissipating heat from the condenser coil. Over time, these fins can become bent or clogged with dirt and debris, which can reduce the efficiency of your AC system. Here’s how to clean the fins:
- Use a soft-bristled brush to gently clean the fins. Be careful not to damage them or bend them.
- If the fins are bent, use a fin comb to straighten them. You can purchase a fin comb at a hardware store or online.
- Use a garden hose to rinse the fins. Be sure to use a gentle stream of water to avoid damaging them.
Step 4: Clean the Coil
The condenser coil is one of the most important components of your outside AC unit. It’s responsible for releasing the heat that your AC system has absorbed from inside your home. Over time, the condenser coil can become dirty or clogged, which can reduce the efficiency of your AC system. Here’s how to clean the coil:
- Use a coil cleaner to remove any dirt or debris from the condenser coil. You can purchase a coil cleaner at a hardware store or online.
- Follow the instructions on the coil cleaner to apply it to the coil.
- Use a garden hose to rinse the coil thoroughly. Be sure to use a gentle stream of water to avoid damaging the coil.
Step 5: Straighten the Fins
After you’ve cleaned the fins and the coil, it’s important to check the fins again and straighten them if necessary. Bent fins can reduce the efficiency of your AC system, so it’s important to straighten them as soon as possible. Here’s how to straighten the fins:
- Use a fin comb to straighten any bent fins. You can purchase a fin comb at a hardware store or online.
- Gently slide the fin comb through the fins to straighten them.
- Be careful not to damage the fins or bend them in the opposite direction.
Step 6: Reassemble the Unit
After you’ve cleaned and straightened the fins and the coil, it’s time to reassemble the outside AC unit. Here’s how to do it:
- Replace the fan cage around the unit.
- Replace the top of the unit and secure it with the screws.
- Turn the power back on to the AC unit.
