The Hidden Menace of Clogged Evaporator Coils

Our trusty HVAC (Heating, Ventilation, and Air Conditioning) systems work tirelessly behind the scenes to keep our indoor spaces comfortable. Yet, all too often, we take these hardworking systems for granted, neglecting the crucial maintenance they require. Annual HVAC service is not just a routine chore; it is a vital investment in the efficiency, performance, and longevity of your system. 

Within the air handler for your HVAC system, usually tucked away in a closet, attic or crawlspace, the evaporator coils play a pivotal role. These coils are responsible for absorbing heat from the indoor air, allowing the cooling process to take place. However, over time, these coils can become clogged with dirt, dust, and debris. This seemingly innocuous buildup can have far-reaching consequences that impact your comfort, energy bills, and even your health:
​

• Cooling Performance Declines: Clogged evaporator coils inhibit the cooling process, leading to uneven cooling, extended cooling cycles, and a persistent lack of comfort.
• Energy Efficiency Takes a Hit: When clogged coils cannot effectively absorb heat, your HVAC system is forced to work harder to achieve the desired temperature. This extra effort translates to increased energy consumption and higher utility bills.
• Indoor Air Quality Suffers: The moisture present in HVAC systems creates an ideal environment for mold, bacteria, and allergens to thrive. Clogged evaporator coils become breeding grounds for these contaminants.
• Premature Wear and Tear: When evaporator coils are clogged, the entire system is strained. This extra workload can lead to premature wear and tear on components, necessitating costly repairs or even an early system replacement.
• Protecting Your Investment: Most HVAC manufacturers require regular maintenance to maintain warranty coverage. Neglecting annual service, including cleaning the evaporator coils, could void your warranty.

Annual HVAC service is not a luxury; it is a necessity. During these service visits, trained professionals clean, inspect, and fine-tune your system, ensuring that clogged evaporator coils, dirty and damaged condenser fins, and other potential issues are addressed. This proactive approach prevents major problems, enhances energy efficiency, maintains indoor air quality, and prolongs the life of your system.
