Our Tempstar keeps up until mid-afternoon in July, then falls behind. Why?

That is when a marginal system shows its limits. Low charge, a dirty outdoor coil or leaky attic ducts cut capacity just as the load peaks. We measure pressures, the temperature drop across the coil and airflow, and fix what is short.

Can the Tempstar in our Cardinet Glen house run quieter?

Often. Noise tends to come from a worn fan motor, a loose panel, a failing contactor or a compressor working against high pressure. A variable-speed system also runs quieter at low speed. We find the source and fix that first.

How often should a Tempstar condenser in Clayton be cleaned?

Once a year before summer, and again after a dusty stretch if the fins look coated. A clean coil runs cooler and uses less power. We rinse it from the inside out and check the fan, capacitor and contactor while we are there.

Tempstar in Clayton

Tempstar heating and cooling in Clayton.

Summers in Clayton are hot and dry, and a Tempstar condenser or heat pump runs long days from early summer into fall. Long runtimes wear the outdoor electrical parts and expose any shortfall in charge or airflow. A unit sized with a load calculation and charged to the nameplate handles the heat. One that wasn't shows it first on the hottest afternoons.

Clayton's housing grew in stages, from the 1970s expansions to Dana Hills, Dana Ridge and Clayton Wood in 1987 and the larger Peacock Creek homes from 1996. A bigger house may carry a variable-speed communicating Tempstar system, which calls for its own diagnostic approach. Our technician who covers Clayton is based in Benicia. A $99 diagnostic, credited toward the repair, starts every call.

Common repairs we handle.

Contactor stuck closed, condenser won't shut off. A pitted contactor can weld shut, so the outdoor unit keeps running after the thermostat is satisfied. The house overcools or the coil ices. We replace the contactor, check the thermostat wiring and the board signal, and test the capacitor while the panel is open.
Evaporator coil leaking in the attic. A slow leak in the indoor coil drops capacity until the system can't keep up in July. We leak-test the coil and line set, repair or replace the coil, and weigh in a fresh charge under ADRIUM's EPA 608 Universal certification.
Variable-speed system showing a fault in a larger home. On a communicating Tempstar system, the control keeps fault history for each component. We read it, test the part it points to, whether the outdoor unit, the variable-speed blower or a sensor, and repair just that.
