AC Repair Frequently Asked Questions

  • How quickly can you respond to an AC repair call?

    We offer same-day AC repair service throughout our Metro Detroit service area. During peak summer periods, response times may vary—contact us at (248) 629-7075 as early in the day as possible to maximize the likelihood of same-day service.

  • Why is my AC running but not cooling?

    The most common causes of an AC system that runs but does not cool effectively include low refrigerant from a leak, a dirty or frozen evaporator coil, a failed compressor, a clogged air filter restricting airflow, or a faulty expansion valve. Our technicians will accurately diagnose the specific cause rather than guessing at the most likely issue.

  • Should I repair or replace my air conditioner?

    The 50% rule is a useful guideline: if the cost of repairs exceeds 50% of the cost of a new system and your unit is more than 10 to 12 years old, replacement is often the better long-term investment. We will give you an honest assessment during our service visit and help you make the right decision for your situation.
