Equipment Details
Furnace, heat pump, and package-unit diagnostics
Heating is seasonal in the Valley, but the equipment is still part of the larger HVAC system. CTS checks whether the issue is the thermostat, electrical controls, airflow, ignition, heating-mode operation, or aging equipment.
Furnaces and heaters
CTS handles furnace repair, heater diagnostics, seasonal tune-ups, and heater or furnace installation when the job is within the service area.
Heat pumps
Heat pump service can include heating-mode operation, comfort complaints, thermostat settings, outdoor-unit behavior, airflow, and temperature checks.
Package equipment
Gas package units and rooftop equipment may need both heating and cooling diagnostics, access planning, safety checks, and commercial scheduling details.
Seasonal tune-ups
Heating tune-ups check startup behavior, thermostat operation, airflow, basic safety concerns, and whether an older system needs deeper service.
