Frequently Asked Questions

  • Keep in mind that a cleanup or a tune-up is different than an inspection. A cleanup and tune-up involves a full cleaning of the entire AC equipment.
  • Air conditioning systems should never leak refrigerant, if your refrigerant has a leak, they should be replaced.
  • An air conditioning system startup and inspection is not just about safety, but preventive maintenance as well. It is about catching a problem before your air conditioner stops working in the middle of the hottest night.
