The answer to 'why is my HVAC system' is that there can be several common causes for HVAC issues, including clogged air filters, low refrigerant levels, thermostat problems, or a malfunctioning compressor. Symptoms may include poor airflow, strange noises, or the system not turning on at all. In many cases, simple DIY troubleshooting and maintenance can resolve the problem, but more complex issues will likely require a professional HVAC technician.
It's important to address HVAC issues promptly, as they can lead to higher energy bills, reduced indoor air quality, and potential damage to the system if left unresolved. Routine maintenance and prompt repairs can help extend the lifespan of your HVAC system and keep it running efficiently.
