Heat Pump Repair in Sacramento & Carmichael

Overview

Heat pumps provide both heating and cooling from a single system — using a reversing valve to switch the refrigeration cycle between summer cooling and winter heating. They are an excellent fit for Sacramento's climate: our mild winters rarely challenge the heating capacity of a modern heat pump, and the long, hot summers give the cooling side a genuine workout. When a heat pump fails, it can leave a home without both heating and cooling, making diagnosis and repair more urgent than a single-function system.

PRO MAX HVAC & Appliance Repair provides same-day heat pump repair throughout Carmichael, Sacramento, Roseville, Citrus Heights, Folsom, Elk Grove, and surrounding communities, seven days a week from 8 AM to 8 PM. Our technicians are trained on the specific components that differentiate heat pumps from straight cooling systems — reversing valves, defrost boards, auxiliary heat strips, and the diagnostic sequences that identify which component is responsible for a given failure.

We service both single-stage and variable-speed inverter-driven heat pumps from all major residential brands. Inverter heat pumps — increasingly common in Sacramento installations — require specialized diagnostic tools and software interfaces that we carry and know how to use.

Common Problems We Fix

• Heat pump not heating in winter — stuck or failed reversing valve
• Heat pump not cooling in summer — refrigerant issue, capacitor, or compressor
• System stuck in cooling mode during winter — O/B thermostat wiring or reversing valve solenoid failure
• Iced over in winter — defrost board not initiating defrost cycles correctly
• Short cycling — compressor protection or refrigerant issue
• Auxiliary heat strips running constantly — heat pump not operating efficiently or refrigerant low
• Not dehumidifying in summer — refrigerant undercharge or airflow restriction
• Error codes on thermostat or control board

Our Repair Process

1. Same-day scheduling — Call (916) 234-5925 any day between 8 AM and 8 PM.
2. On-time arrival — We provide a service window and call when the technician is en route.
3. Full heat pump diagnostic — Your technician tests both heating and cooling modes, checks refrigerant charge, tests the reversing valve solenoid, reads error codes, and inspects the defrost board and auxiliary heat strips.
4. Upfront quote — A clear, itemized quote is provided before any repair work begins.
5. 180-day warranty — Every heat pump repair is backed by our 180-day parts and labor warranty.

Warranty & Guarantee

PRO MAX backs every heat pump repair with a 180-day parts and labor warranty. If the same issue returns within six months of our repair, we come back at no additional charge. Heat pump repairs often involve multiple interacting systems — refrigerant, electrical controls, and mechanical components — and our warranty reflects our confidence in the diagnostic work, not just the part we replaced.

Why Sacramento Residents Rely on PRO MAX

Heat pumps require a technician who understands both cooling and heating diagnostics — a reversing valve failure looks different from a refrigerant issue, and a defrost board problem can be misdiagnosed as a low-charge condition by technicians unfamiliar with heat pump operation. Our technicians are trained on heat pump-specific diagnostic procedures and carry the tools required to test each subsystem independently.

Sacramento's climate also creates a specific failure pattern in heat pumps: the reversing valve and defrost board sit unused through most of the long Sacramento summer, and then they are called on during the first cold week of the season. We see this pattern routinely and diagnose it quickly.
