Why your AC is not cooling or blowing warm air in Lake Mary
Four groups cause it, and they are indistinguishable at the register: airflow (blocked filter, dirty evaporator coil, failed blower), electrical (tripped breaker, failed capacitor or contactor), refrigerant (a leak — which is a repair, not a top-up), and the compressor. Only a measurement separates them.
The refrigerant answer that should worry you
“It is low on refrigerant, we topped it up” is not a repair. A sealed system does not consume refrigerant. If it is low, it leaked, and the leak is still there. Under 40 CFR Part 82 subpart F a technician servicing appliances must be Section 608 certified and must observe leak-repair requirements; a top-up with no leak search is a bill you will pay again next season.
It matters more now than it did five years ago. New residential equipment has shipped on R-454B and R-32 since the 700-GWP manufacture and import date of 1 January 2025 under EPA’s Technology Transitions rule, and R-410A production is being drawn down under the HFC phasedown. R-410A is not banned and your system can still be serviced — but the price of what goes back in is the variable to watch, and that changes the maths on whether a recurring leak is worth chasing. See the refrigerant transition page.
The question, in the wording people ask it
Why is my AC not cooling or blowing warm air?
The common causes split into four groups: airflow (a blocked filter, a dirty evaporator coil, a failed blower), electrical (a tripped breaker, a failed capacitor or contactor), refrigerant (a leak, and a leak is a repair not a top-up), and the compressor itself. They present identically at the register. The diagnosis is a measurement — superheat or subcooling, amperage, static pressure — so ask for the reading, not just the verdict.
