coleman rooftop unit

i guess it depends on age of unit. having been in HVAC field you can tell the difference between a unit 10 yrs old and something 1-2 yrs old in efficiency and cost to run.

It will cost more to get a new one installed for sure, but depending on what the issue you have going one is the repair may be half the cost of a new one.

Guess you have to decide to spend more now and get the benefit of better technology or spend the same over time with lower efficiency = higher operational cost.

'not working' encompasses a wide variety of problem areas. Can you be a little more specific as to what exactly is not working? No fan motor, no compressor, nothing happens when you turn it on. Is there sufficient 120VAC power to the unit thru the circuit breakers?

Answers to questions like these would go a long way to help diagnose your problem.
