The answer to 'should I get duct cleaning or' is that duct cleaning can provide some benefits, but it's not always necessary. Duct cleaning is the process of removing dust, debris, and other contaminants from the ductwork in your HVAC system. This can help improve indoor air quality and the efficiency of your system, but it's not required on a regular basis for most homes.
The main benefits of duct cleaning include reducing dust and allergens in your home, improving airflow, and potentially saving on energy costs if your ducts were significantly blocked. However, duct cleaning can be expensive, costing several hundred dollars or more, and it's not always necessary unless you have visible mold growth, pests, or excessive dust buildup in your ducts.
