Expert Heat Pump Repair in Pasadena, CA
When your heat pump stops working, your home’s comfort comes to a halt. Whether it’s failing to cool your home during a Pasadena summer or leaving you cold on a winter night, a malfunctioning system is a significant disruption. You need a fast, reliable solution from local experts who understand the unique demands of our climate. We provide comprehensive heat pump repair services designed to diagnose the root cause of the problem and restore your system to peak performance quickly and efficiently.

Common Heat Pump Problems We Solve
Heat pumps are complex systems, and a single symptom can point to several potential issues. Our experienced technicians are skilled at identifying the precise cause of failure. Here are some of the most common problems Pasadena homeowners face:
- Heat Pump Not Heating or Cooling: If your system is running but the air from your vents isn’t the right temperature, it’s a clear sign of a problem. This could be caused by a refrigerant leak, a faulty reversing valve that’s stuck in one mode, or a failing compressor.
- Unusual or Loud Noises: Your heat pump should operate with a low, consistent hum. Grinding, squealing, or rattling noises often indicate mechanical issues, such as worn-out motor bearings, loose components, or a problem with the fan blades. Hissing or bubbling can signal a refrigerant leak.
- System is Short Cycling: Does your heat pump turn on and off every few minutes? This is known as short cycling, and it puts excessive strain on the system. It can be caused by something as simple as a clogged air filter, but it may also point to an oversized unit, thermostat issues, or low refrigerant levels.
- Frozen Outdoor Coils: While it’s normal for a heat pump to develop a thin layer of frost during its defrost cycle in winter, a thick buildup of ice on the outdoor unit is not. This can be caused by a dirty air filter restricting airflow, low refrigerant, or a malfunctioning defrost control board.
- Sudden Spike in Energy Bills: A heat pump that is struggling to perform will consume significantly more energy. If you notice an unexplained increase in your utility costs, it’s often one of the first signs that your system needs professional attention.
What to Check Before You Call for Service
Before scheduling a repair, there are a few simple steps you can take that might solve the problem and save you a service call.
- Check Your Thermostat: Ensure it is set to the correct mode ("Heat" or "Cool") and the temperature setting is appropriate. A dead battery can also cause issues, so replace them if your thermostat is battery-operated.
- Inspect the Air Filter: A dirty, clogged air filter is the number one cause of HVAC problems. It restricts airflow, forcing your system to work harder and leading to overheating or freezing. Check your filter and replace it if it’s dirty.
- Check the Circuit Breaker: Locate the circuit breaker for your indoor and outdoor units in your home’s electrical panel. If a breaker has tripped, reset it once. If it trips again, do not reset it and call a professional immediately, as this indicates a serious electrical issue.
If these simple checks don’t resolve the issue, it’s time to call for professional assistance. Attempting further DIY repairs can be dangerous and may cause more extensive damage to your system.
Our Diagnostic and Repair Process
We believe in a transparent and thorough repair process. When our technician arrives at your Pasadena home, you can expect a systematic approach to getting your comfort back.
- Comprehensive System Diagnosis: We don’t just fix the symptom; we find the source. Our technician will perform a detailed inspection of your entire heat pump system, including the indoor air handler and the outdoor unit, to accurately identify the fault.
- Clear Explanation and Upfront Quote: Once the problem has been identified, we will explain the issue to you in clear, understandable terms. We will outline the necessary repairs and provide you with a straightforward, upfront quote before any work begins.
- Professional, High-Quality Repair: With your approval, our certified technician will perform the repair using high-quality parts and industry-best practices. We ensure every repair is done right the first time, from sealing a refrigerant leak to replacing a faulty motor.
- Final System Testing: After the repair is complete, we don’t just pack up and leave. We test your heat pump to ensure it is operating correctly, safely, and efficiently, confirming that your home’s comfort has been fully restored.
Is It Time to Repair or Replace Your Heat Pump?
For Pasadena homeowners with an older system, a major breakdown often raises the question of whether to repair or replace the unit. We provide honest guidance to help you make the most cost-effective decision. Consider these factors:
- Age of the System: A typical heat pump has a lifespan of 10-15 years. If your unit is approaching or has surpassed this age, investing in a major repair may not be the best long-term solution.
- Cost of the Repair: A common guideline is to consider replacement if the cost of a repair is 50% or more of the cost of a new system. For major component failures like the compressor, replacement is often the more sensible financial choice.
- Frequency of Breakdowns: If you are calling for repairs multiple times a year, those costs can quickly add up. A new, reliable system can provide peace of mind and more predictable energy bills.
- Energy Efficiency: Modern heat pumps are significantly more energy-efficient than models from a decade ago. Upgrading can lead to substantial savings on your monthly utility bills, helping the new system pay for itself over time.

Echoing a lot of the other reviews here, Piggies Air Conditioning responds so quickly to requests (even though I actually accidentally sent in multiple requests on my side without responding, oops!)
They were able to come do a FREE energy audit and initial inspection on the same day and Ruben was amazing at explaining his thoughts on our house's situation and what he thought was worth the money and wasn't worth the money.
I truly felt like he was trying to help me find the best solution to our issues instead of just trying to upsell us on everything and anything.
I'm definitely recommending this business to anyone I know if they want a trustworthy and realistic service, value, and quality.
