AC Not Cooling
Air runs but the house stays warm. A provider checks filter, coil, charge and airflow to find why.
Many Indio homes cool all summer and heat on cold winter nights with the same outdoor unit. When a heat pump stops working in one mode or both, the parts involved are a little different from a straight air conditioner.
Indio AC Repair is a free referral service. Calls are answered by independent local providers who set their own prices.
Heat pump repair in Indio covers systems that both cool and heat with one outdoor unit. Besides the usual AC parts, a technician checks the reversing valve, the defrost controls and the heat strips, then explains what failed and the price before any repair.
A heat pump is an air conditioner that can run in reverse. In summer it pulls heat out of the house and releases it outside, just like a central AC. In winter a reversing valve changes the direction of the refrigerant, so the outdoor coil collects heat from the outside air and the indoor coil releases it into the house. One system does both jobs.
Heat pump repair covers everything an air conditioner can need, plus the parts that make heating possible. Those include the reversing valve and its solenoid, the defrost control board and sensors, and the backup electric heat in the indoor unit. Because the system runs in both seasons, it also tends to log more hours than a cooling-only unit.
In Indio, cooling is the main job. Winter nights do get chilly, with January lows commonly in the 40s, so the heating side still matters for a few months. When you call, the provider asks which mode is failing and what the system is doing. For problems that are purely about cooling, the page on AC not cooling may also help, and every service is listed on AC repair Indio.
The technician confirms whether the problem is in cooling, heating or both, and checks the thermostat setup for a heat pump.
The capacitor, contactor, reversing valve solenoid and defrost board are tested with a meter.
Pressures and temperatures are checked in the mode that is failing to see whether the charge and valve are working.
The blower, filter and backup heat strips are checked, since they affect both comfort and the electric bill.
It cools but will not heat, or the other way around.
The thermostat shows auxiliary or emergency heat running for long periods.
A short whoosh when the valve switches is normal; constant noise is not.
The outdoor coil stays covered in frost or ice for a long time.
The unit starts and stops every few minutes.
Less air from the vents in either mode.
Bills jump in cold months, often a sign backup heat is doing the work.
The outdoor fan does not spin while the compressor runs.

Call 24/7 (760) 986-1343Long summer duty is the biggest factor. A heat pump in Indio does the same hard cooling work as any air conditioner, through afternoons that average close to 106 degrees in July. Capacitors, contactors and fan motors wear out on the same schedule as on a cooling-only system, and a dirty outdoor coil makes everything run hotter.
The reversing valve is a part that a cooling-only system does not have. It can stick in one position, often after a long period without switching, such as when a system has run in cooling mode for months and then is asked to heat on the first cold night of the season. A failed solenoid coil or a wiring fault in the control circuit can cause the same symptom.
Thermostat setup is another frequent cause. A heat pump needs a thermostat configured for heat pump operation, with the reversing valve wired and set correctly. After a thermostat replacement, a heat pump that suddenly heats when it should cool, or the reverse, often points to a setting rather than a failed part. Refrigerant leaks affect both modes; see refrigerant leak repair for how those are found.
If your heat pump suddenly works backward after a new thermostat was installed, check the thermostat's system type setting before anything else. A wrong reversing valve setting is a common and easy fix.
The low desert is kind to heat pumps in one way: the winters are mild. Heat pumps lose capacity as the outdoor air gets colder, and in places with long freezing spells they lean heavily on backup heat. In Indio, most winter nights are well above the temperatures that cause trouble, so a working heat pump can heat a home efficiently.
That is one reason the Imperial Irrigation District, which supplies electricity in Indio, has encouraged heat pumps through rebate programs, including incentives for replacing gas heating equipment. Programs change from year to year, so check IID's current offers before planning a replacement, and ask whether the rebate requires a particular efficiency level or an approved contractor.
On the cooling side, a heat pump should be sized and maintained like any desert AC. If the system is near the end of its life and needs a major part, the provider can explain repair versus replacement. Replacement in California generally involves a permit and, on most jobs, third-party verification under the state energy code.

In summer, a heat pump that will not cool is just as urgent as a failed air conditioner. If the house is heating up and someone at home is vulnerable to heat, call for help quickly and use the cooling steps on our emergency AC repair page while you wait.
In winter, a heat pump stuck on emergency heat is less dangerous but can be costly, because electric heat strips use far more power than the heat pump itself. If you see a burning smell when the heat strips come on for the first time in the season, a little dust burning off is common; a strong or lasting electrical smell is not. Turn the system off and call.

Call 24/7 (760) 986-1343Do not keep resetting a breaker that trips when the heat pump or its backup heat starts. Repeated tripping points to an electrical fault that needs a technician.
Because a heat pump works in two seasons, a yearly check is especially worthwhile. Many owners in the desert schedule service in spring, before cooling season, and ask the technician to confirm the heating side and the reversing valve at the same time. Keeping the outdoor coil clean and the filter fresh helps in both modes.
When a heat pump reaches the end of its life, ask for a proper load calculation before choosing the replacement size. A system that is too large cycles on and off and handles humidity poorly; one that is too small runs constantly in July. Getting the size right matters more than any single feature.
In cooling mode they work the same way. A heat pump also has a reversing valve that runs the refrigerant the other way in winter, so the outdoor unit gathers heat from outside air and moves it indoors.
Common causes include a reversing valve that is stuck, a problem with the valve's control, thermostat settings or wiring, or low refrigerant. A technician can test each one.
During a defrost cycle the system briefly switches to cooling mode to melt frost on the outdoor coil. In Indio's mild winters that is less common than in cold climates, but if it happens often or for a long time, the defrost controls may need checking.
Winters are mild, so a heat pump rarely has to work at the very low temperatures that challenge it elsewhere. That makes it a practical choice here, and IID has offered rebates for heat pumps that replace gas equipment.
They are electric heaters in the indoor unit that add heat when the heat pump cannot keep up or is defrosting. They use much more electricity, so a system stuck on emergency heat can raise the IID bill quickly.
It depends on the age of the equipment. Newer systems use lower-impact refrigerants under the federal AIM Act phase-down. A technician will use whatever your system was designed for.
