The answer to 'should I get AC repair or' is that it depends on the specific issue with your air conditioning system. If the problem is a minor one, such as a clogged filter or a loose connection, then AC repair may be the best option. However, if your system is older, less efficient, or has more significant problems, it may be better to consider replacing it with a new, more energy-efficient AC unit.
When deciding between AC repair and replacement, consider factors like the age of your system, the cost of repairs, and the potential energy savings from a new unit. It's also a good idea to consult with a professional HVAC technician, who can assess the condition of your system and provide a recommendation based on your specific needs and budget.
