With today’s high and ever increasing energy costs one of the simplest, cost-effective and green things you can do for your building’s energy efficiency is to have its HVAC system’s condenser and evaporator coils inspected every year and cleaned as necessary. A system with dirty coils forces the compressors to run longer and harder than required, increasing your energy costs while at the same time causing a decrease in component life and the users level of comfort. In a recent study conducted by the U.S. Department of Energy, they found that a dirty condenser coils can increase energy consumption by as much as 30%, and significantly increase the failure rate of the systems motors due to increased heat while running. From our experience when dirty systems seem to be working poorly and service is called in, the problem is easily misdiagnosed, and this very often results in a mistaken overcharging of the system and their premature breakdown.
It is often mistakenly thought that only old systems need cleaning, whereas in fact the newer and more efficient your HVAC system is, the more likely it is to benefit from regular coil inspection and cleaning. The newer systems today work at much higher pressures and demand efficient heat transfer across larger coils in order to function efficiently and to their full capacity. With the increasing popularity of HVAC systems using variable-speed motor technology, they can lose much of their effectiveness when forced to run harder than necessary due to dirty and clogged condenser vanes.
Another and very important factor to consider when cleaning HVAC systems is the importance of maintaining a clean and hygienic indoor air circulation. A dirty evaporator coil can have negative effects on indoor air quality. It is an ideal breeding ground for germs, bacteria and mold. These colonies not only interfere with heat transfer and obstruct the airflow but serve as an ongoing source of mold spores in your indoor air. These microorganisms have been linked with allergies, asthma and other respiratory symptoms and can be harmful to your health.
All equipment, even the most reliable, needs routine maintenance to maintain its efficiency. Complicated equipment like today’s air conditioners benefit in many ways from an annual service. They recover much of their lost efficiency, they are less likely to suffer a major break down, they will have a longer life span, and it will increase your comfort, and of course it will save you money in the longterm.
