Cleaning Your AC Coils

AC coils play a crucial role in an air conditioning system's efficiency and performance. Over time, dirt, dust, and debris accumulate on the coils, reducing cooling effectiveness and forcing the unit to work harder. While some homeowners may attempt to clean their AC coils themselves, improper cleaning can lead to damage or inefficiency.

This guide explains the importance of cleaning AC coils and covers the following topics:

• Why AC coil cleaning is essential
• Types of AC coils: Evaporator vs. condenser
• How AC coils are cleaned
• Risks of DIY AC coil cleaning
• Benefits of professional AC coil maintenance

Let’s learn more about cleaning AC coils and why hiring a professional is the best choice for ensuring safe, effective maintenance.

Keeping AC coils clean is crucial for maintaining an efficient cooling system. Dirty coils can lead to:

• Reduced cooling efficiency, making the system work harder and increasing energy bills
• Increased risk of breakdowns from overheating and excess strain on the AC compressor
• Decreased indoor air quality from circulating dust and debris
• Shortened lifespan of the AC unit from added wear and tear

Regular cleaning of AC coils inside and outside your home ensures optimal performance, lowers energy costs, and extends the life of the cooling system.

AC systems have two main types of coils that require routine cleaning and maintenance:

• Evaporator coils. These are indoors and absorb heat from the air inside your home, allowing the refrigerant to cool it before circulating it back.
• Condenser coils. These are outdoors and release absorbed heat outside, helping to regulate temperature efficiently.

Both coil types can accumulate dirt and grime, affecting overall system performance.

Professional AC coil cleaning involves several essential steps to ensure thorough maintenance. Proper cleaning involves:

1. Inspection. Technicians assess the level of buildup and determine the best cleaning method.
2. Removing debris. Loose dirt, dust, and leaves are cleared from around the coils.
3. Applying a cleaning solution. A specialized coil cleaner is sprayed to break down stubborn grime.
4. Gentle rinsing or brushing. Depending on the coil type, professionals use a low-pressure rinse or soft brush to remove residue.
5. Checking for damage. After cleaning, technicians inspect the coils for potential leaks, corrosion, or wear.

Skipping steps or using improper cleaning techniques can damage coils, reducing efficiency and leading to costly repairs. AC coil cleaning costs less than prematurely replacing your AC unit.

While cleaning AC coils inside and outside your home may seem simple, DIY attempts often cause more harm than good. The risks of cleaning AC coils yourself include:

• Using the wrong cleaning products. Some household cleaners can corrode or damage coils.
• Bending or damaging fins. Scrubbing too hard can mangle the delicate fins, restricting airflow.
• Exposing yourself to electrical hazards. Handling AC components without proper knowledge increases the risk of shock.
• Missing issues. A professional can spot problems that homeowners might overlook, like refrigerant leaks or coil corrosion.

These and other risks make it best to leave AC evaporator coil cleaning and condenser coil cleaning to trained HVAC professionals.

Hiring an HVAC professional for AC coil cleaning provides several advantages, including:

• Thorough and safe cleaning. Experts use industry-approved methods to ensure effective results.
• System longevity. Routine maintenance helps prevent costly breakdowns and extends your AC’s lifespan.
• Energy efficiency. A clean system operates more efficiently, lowering energy bills.
• Comprehensive inspection. Professionals check for additional issues, ensuring the system is in peak condition.

Scheduling regular maintenance keeps the AC unit running smoothly and prevents costly repairs down the road, making professional AC coil cleaning well worth the cost.
