The answer to 'should I get installation or' is that it depends on your specific situation and needs. Professional HVAC installation is generally recommended for most homeowners, as it ensures the system is properly sized, installed, and configured for optimal efficiency and performance. DIY installation can be more cost-effective, but it also carries more risks if not done correctly.
Some key factors to consider are the complexity of your HVAC system, your own technical expertise, and the potential long-term costs of improper installation. Professional installation typically includes a warranty and ongoing support, which can be valuable if issues arise down the line. For most homeowners, the benefits of professional installation outweigh the upfront costs.
