Homeowners frequently ask AC contractors about the temperature of the air coming out of their registers. If you’re wondering if you need air conditioning repair in Edison, watch this video to understand how cold your air conditioner should be throughout the day.

If you speak to an air conditioning repair specialist about the temperature coming from your AC, he may use the term “Delta T.” Delta T refers to the temperature difference between the supply and the return. Experts recommend that your HVAC system’s Delta T be between 15ºF and 18ºF. If your AC’s Delta T is higher or lower than this, then you may need air conditioning maintenance.
