A dirty evaporator coil can cause several problems, including poor airflow, reduced cooling performance, unpleasant odors, and an overworked compressor. If left unchecked, these issues can lead to higher energy bills, unnecessary wear and tear on your system, and costly repairs. Regular maintenance and coil cleaning help keep your HVAC system running efficiently and extend its lifespan.

If your system isn’t cooling properly or has a musty smell, give 3G a call for all your residential and commercial HVAC needs.
