No, it is not too late in July to have your AC maintenance done. Regular maintenance is essential for ensuring your AC unit operates efficiently throughout the hot summer months. While it’s ideal to perform maintenance before the peak cooling season, scheduling it in July can still help identify and resolve any issues, improve energy efficiency, and extend the lifespan of your unit. An HVAC professional can clean and inspect your system, check refrigerant levels, and ensure all components are functioning properly, providing reliable cooling for the remainder of the summer.
