Air Conditioning FAQs

How long will my AC unit last?

Most air conditioners last 12 to 15 years, though those that have been maintained exceptionally well can last 20 years or longer. To maximize the service life of your air conditioner, replace the air filter often, keep the outdoor coil clean and free of debris, and schedule AC maintenance at least once a year. When you need a new, more efficient air conditioner, talk to our experts at David Gray.

When should I service my air conditioner?

The summers in St. Augustine can be brutal, and they can put extreme stress on your air conditioning system. Because of this, our team at David Gray recommends at least one AC maintenance visit a year, but preferably two, one in the spring and one in the fall.

Why is my AC freezing up?

A frozen evaporator coil is usually caused by something minor, like a clogged air filter, a dirty evaporator coil, a dirty condenser coil, or a blocked return vent. In some cases, it can be caused by something more serious, such as a faulty compressor or condenser fan. To be sure, call our team at David Gray to thaw the system and find the cause of the problem.
