The answer to 'why is my installation' is that there could be several common causes for issues with an HVAC installation. Some of the most frequent problems include improper sizing, incorrect ductwork, electrical wiring issues, refrigerant leaks, and inadequate airflow. These can lead to symptoms like inconsistent temperatures, high energy bills, strange noises, or even complete system failure.
If you're experiencing problems with your HVAC installation, it's best to have a professional technician inspect the system. They can diagnose the specific issue and recommend the appropriate solution, whether that's adjusting the installation, repairing components, or potentially replacing the entire system. While some minor troubleshooting can be done DIY, HVAC work often requires specialized knowledge and tools, so it's generally advisable to call in an expert unless you have extensive experience.
