Is Coil Cleaning Really Necessary?

Krystle Hartmann • August 13, 2025

In the world of HVAC maintenance, the necessity of coil cleaning is a topic often debated. However, given the critical role that condenser and evaporator coils play in the efficient operation of your air conditioning system, understanding the importance of keeping these components clean is essential for homeowners and businesses alike.


The Controversy Around Coil Cleaning
A study once claimed that dirty A/C coils do not significantly impact the efficiency of air conditioning systems. According to the findings, systems with dirty coils were able to transfer heat nearly as effectively as those with clean coils, leading some to question the importance of regular coil maintenance. However, this conclusion overlooks a major flaw in logic.

Why Clean Coils Matter
Even if a unit releases air at the same temperature, it doesn't necessarily mean it's performing at the same efficiency level. In reality, air conditioners with dirty coils often compensate for reduced heat transfer by overworking the compressor. This added strain increases energy consumption and can lead to accelerated wear and tear on the system. Ignoring coil cleaning based on the study's limited scope may result in higher utility bills and a shorter HVAC system lifespan.

The Role of Coil Cleaning in HVAC Maintenance
Coil cleaning is not just another maintenance task; it's essential for efficient and reliable HVAC system performance. Dirty coils can:
  1. Decrease energy efficiency
  2. Increase operating costs
  3. Cause the system to overheat or fail prematurely
  4. Reduce indoor air quality due to the buildup of dust, mold, and other pollutants
Regular coil cleaning supports optimal system function and healthier indoor air, especially during the summer when your A/C is working its hardest.

Professional Coil Cleaning: A Smart Investment
For homeowners and businesses looking to avoid DIY tasks, professional coil cleaning is a worthwhile investment. HVAC technicians can perform a comprehensive system tune-up, including cleaning the condenser coils thoroughly. This ensures peak performance, extends system lifespan, and helps maintain a comfortable indoor environment even during the hottest days of summer.

6 Signs You're Due for an HVAC Upgrade Your HVAC system plays a critical role in maintaining indoor comfort and air quality, especially during the peak of summer or winter. Like any major appliance, it has a limited lifespan and recognizing when it's time for an upgrade can save you from discomfort, inflated energy bills, and emergency repairs. Here are some key signs that it may be time to replace your HVAC system. 1. Soaring Energy Bills A noticeable increase in your utility bills, without any significant change in usage, is often a red flag. As HVAC systems age, they lose efficiency, forcing them to work harder to maintain indoor temperatures. This extra effort consumes more energy, which is reflected in your monthly costs. If your bills are steadily rising, it could be time to consider an energy-efficient upgrade. 2. Frequent Breakdowns and Repairs If you're calling your HVAC technician more often than you used to, your system may be nearing the end of its useful life. Frequent repairs not only drain your wallet but also indicate that components are wearing out. At a certain point, upgrading to a new unit becomes more cost-effective than constantly fixing an old one. 3. Inconsistent Temperatures and Comfort Levels Hot and cold spots in your home or business are often a sign of an HVAC system that's struggling to distribute air evenly. Uneven comfort levels can also stem from aging ductwork or outdated thermostats. Modern HVAC systems are equipped with advanced zoning capabilities and smart controls that ensure consistent temperatures throughout your space. 4. Your System Is More Than 10-15 Years Old The average lifespan of an HVAC system is around 10 to 15 years, depending on the make, model, and how well it's been maintained. Older systems are less efficient and may not be compatible with newer technologies. If your unit is over a decade old, it's likely time to start planning for a replacement. 5. Poor Indoor Air Quality An aging HVAC system can compromise your indoor air quality, contributing to excess dust, mold growth, or humidity issues. If you're noticing more allergy symptoms, strange odors, or condensation on windows, your system may not be properly filtering or ventilating the air. A new system with advanced filtration can dramatically improve indoor air quality. 6. Outdated Technology and Features HVAC technology has come a long way in recent years. If your current system lacks compatibility with smart thermostats, energy monitoring tools, or variable-speed components, you're missing out on features that can boost both comfort and efficiency. Upgrading allows you to take advantage of the latest energysaving innovations.
