Heat Pump Repair in Riverside
A heat pump that stops heating in December usually fails in August. It is the only equipment in a Riverside house that works both seasons on the same compressor. Most winter callouts trace back to a part that ran all summer.

First Class Plumbing and AC has repaired ducted and ductless heat pumps across Riverside since 2019. Whether your heat pump blows cool air, struggles to maintain temperature, cycles too short, or refuses to start, we identify the cause and explain repair options before work begins.
Riverside Heat Pumps Need More Than a Cooling Check
Riverside’s climate puts a heat pump through a very different workload than it experiences in colder parts of the country. California Energy Commission research found that Riverside County has much greater cooling loads than heating loads, meaning the system can spend substantially more time operating in cooling mode before heating is needed.
At First Class Plumbing and AC, we take that into account when diagnosing heat pumps. A system that cools properly is not necessarily ready for winter; heating operation depends on components such as the reversing valve, defrost controls, sensors, and controls that may not be fully exercised during cooling.
We have repaired ducted and ductless heat pumps throughout Riverside since 2019. We test the system in the mode where the problem occurs, identify the failed component, and explain the repair before work begins.

Our Heat Pump Repair Services
Reversing Valve and Solenoid Faults
The reversing valve switches the heat pump between heating and cooling. We diagnose valve and solenoid problems that can cause the system to get stuck in one mode.
Refrigerant Leak Detection and Charge Correction
We look for the source of refrigerant loss rather than simply adding more refrigerant. A proper repair addresses the leak and restores the system to the correct charge.
Thermostat and Control Faults
We diagnose thermostat and control problems, including thermostats that were never properly configured for heat pump operation.
Ductless Mini Split Repair
We repair ductless systems in older Riverside homes, converted garages, ADUs, and other spaces where conventional ductwork may not be practical.
Airflow and Duct Diagnosis
We check airflow and ductwork to determine whether restrictions or leakage are affecting performance.
What Customers Say About Us
Through Diagnosis and Fault Detection
Dennis Rankin installed a ductless mini-split himself and could not work out why it would not heat. We sent our technician, Nick Valdez, the same day. The unit was not faulty. It was wired to a circuit supplying half the voltage it needed, which is an electrical problem rather than an HVAC one.
“He told me I needed 220v when I was only getting 120V. Even though it was electrical, he stuck around instead of leaving and helped me figure it out with a good attitude the whole time…”
Dennis added that Nick helped him work it out with a good attitude throughout, and that he would recommend us to neighbors, family, and friends. Read Dennis’s full Google review.
The Installation Was Nothing Less Than Miraculous (One Day)
Robin Britzman had used us before and came back for a full heating and air conditioning system. Luke, Vladimir, and Victor completed the changeout in a day.
“These guys are definitely first class. The second job we have called on them to do for us. This time, a new Heating/A/C System. Not only was their response time great, but the installation was nothing less than miraculous (one day). Special thanks to Luke, Vladimir and Victor; you guys rock! 10 out of 5 stars.”
The crew that installs a system also services it, which counts when a warranty question arrives two winters later. Read Robin’s full Google review.

FAQs About Heat Pump Repair in Riverside, CA
Why does my heat pump cool fine but not heat?
Because cooling and heating use different parts of the same machine, and only one set gets exercised in a Riverside summer. When a system cools normally and fails to heat, the usual suspects are the reversing valve or its solenoid, the defrost control, or a thermostat that was never configured for heat pump operation. In a climate with a short heating season, those components can sit in one position for the better part of a year, and a valve that has not shifted in ten months is exactly the kind of part that sticks when it is finally asked to. A technician who tests only in cooling mode will find nothing wrong.
Does California require me to replace my furnace with a heat pump?
No. The California Energy Commission states that the 2025 Energy Code, which took effect on January 1, 2026, does not mandate specific technologies or fuel types, while noting that it encourages heat pumps for heating and cooling air and for water heating. So a heat pump is an option the code favors in its energy budgets, not an obligation placed on a Riverside homeowner replacing a system. Anyone telling you the state requires you to convert is selling something. What the code affects is how a new system is designed and documented, which is a conversation about a replacement rather than a repair.
Should I repair or replace my heat pump?
The variables are the system’s age, what failed, and which refrigerant it runs on. A capacitor, contactor, or sensor on a system under about ten years old is a repair every time. A failed compressor or reversing valve on a system in its teens, running a refrigerant that is no longer manufactured, is usually the point at which repair money is better spent on replacement. We give you both numbers and the reasoning rather than the recommendation alone, because in Riverside a heat pump carries the cooling load as well, and the cost of it failing again in August is part of the calculation.
When should I have my heat pump serviced in Riverside?
Autumn, and for a reason specific to how these systems are used here. A heat pump that has just finished a long Riverside cooling season has run its compressor, contactor, and outdoor fan hard, while its heating-side components have sat untouched. An autumn service catches summer wear before the heating season and exercises the reversing valve and defrost control before you depend on them. A spring visit before the cooling season is the second one worth booking, since this equipment does two jobs and has no off-season.
Do you repair ductless mini split heat pumps?
Yes, including systems installed by others and by the homeowner. Mini-splits are common in Riverside as retrofits into houses without ductwork, converted garages, and ADUs, and a large share of the faults we find with them are not equipment faults at all. Voltage supplied to the unit, condensate drainage, line set installation, and remote or control configuration account for a great many calls. We diagnose both the installation and the unit, because replacing a board on a system being fed the wrong voltage fixes nothing.
