Why is my AC running but not cooling?
Common causes include low refrigerant, a dirty coil/filter, a failing capacitor/contactor, or a TXV/EEV issue. We test temps, pressures, and airflow to pinpoint the fault.
Why does ice form on my refrigerant lines or coil?
Low airflow (dirty filter/coil, duct restrictions) or incorrect refrigerant charge can cause icing. Shut the unit off and call us to prevent compressor damage.
Water is leaking from my furnace/air handler—what now?
You may have a clogged condensate line or a failed pump/float switch. We clear blockages, test the pump, and ensure proper slope and trap.
Do you service ductless systems?
Yes—indoor heads, thermistors, communication wiring, drain lines, and outdoor units for single or multi-zone systems.
How long does a repair take?
Many fixes are same-day. Special-order parts or concealed refrigerant leaks may require a return visit once parts arrive.
Will repairs affect my warranty?
We follow manufacturer procedures and use OEM-grade parts to help preserve eligible warranties.
