Master's Plumbing tunes up central air, heat pumps and ductless systems across North Jersey. It is a real inspection with gauges and a meter, not a quick rinse of the outdoor unit.
Signs your system is overdue for a tune-up
- It has been more than a year since anyone opened the unit
- The outdoor coil is packed with cottonwood fluff, grass clippings or dryer lint
- The system runs longer than it used to on the same kind of day
- A musty smell from the vents when it first starts
- Water in the drain pan or around the air handler
- Ice on the lines at any point last summer
What the tune-up includes
Outdoor coil cleaning
We wash the condenser coil from the inside out so it can shed heat. A coil caked in pollen and dirt runs hotter, longer and harder.
Indoor coil and blower inspection
The evaporator coil is checked for dirt and biological growth, and the blower wheel for buildup that cuts airflow.
Refrigerant charge check
Pressures and temperatures are measured against the manufacturer's specification. A low reading means a leak, and we tell you before it becomes a compressor problem.
Condensate drain flush
The drain line is cleared and treated, the trap checked and the float switch tested. This is the step that prevents the ceiling stain in August.
Electrical testing
Capacitor values, contactor condition, motor amp draw and wire connections. Weak parts are flagged with a price so you can decide.
Thermostat and airflow check
Calibration, temperature split across the coil, filter condition and any duct problems visible from the equipment.
How it works
- 1
Schedule in spring
April and May are ideal. The system gets checked before the first heat, and you get a convenient appointment instead of a wait during a heat wave.
- 2
Inspection and cleaning
The technician works through the full checklist on both the indoor and outdoor units.
- 3
Plain-language report
A summary of what we found, what we cleaned or adjusted, and anything that is wearing out.
- 4
Any repairs, priced up front
If something needs replacing we quote it by the job. Nothing is done without your go-ahead.
