An HVAC unit with a SEER rating of 14 or higher is recommended for optimal performance. Not only does this save money on energy bills, but it also contributes to a more eco-friendly home.Installation and Maintenance TipsProper installation is crucial for the efficient operation of your HVAC unit. Be sure to hire licensed professionals who can ensure that the system is installed correctly. Regular maintenance checks will also help prolong the lifespan of your unit and maintain its efficiency.
