Common Air Conditioner Repairs in San Jose

San Jose residents rely on their air conditioning systems to maintain comfortable indoor temperatures all year long. However, like any mechanical system, AC units can develop issues that require attention over time. 

• Refrigerant Leaks. Refrigerant is what your air conditioner uses to remove heat and humidity from your space, whether it's your office or your home. One common problem that can occur is refrigerant leaks, which can impact your system’s ability to cool effectively while increasing energy consumption. Left unresolved, refrigerant leaks can also strain the unit, leading to more significant repairs down the line.
• Condenser Unit Issues. The condenser unit is a crucial component of your air conditioning system, responsible for releasing the heat absorbed from inside your home. When it’s not functioning properly, it can significantly affect the overall performance of your AC system. Common signs of an issue with your condenser are warm air, the blades not rotating, unusual sounds and frequent powering down.
• Thermostat Malfunctions. If your thermostat isn’t accurately reading temperatures or communicating with your system, you may experience uneven cooling or heating in your space. This can make your home less comfortable and cause unnecessary wear on your HVAC system. 
• Leaking Ducts. Ductwork is often an overlooked issue that can lead to air conditioner repairs. Your ducts run from your air conditioner, through your home, and deliver cold or hot air into each room. If there are holes or escaping air, it’s going to cause two main problems: poor airflow, and increased energy bills. Since air is escaping behind your walls, and not into the rooms it is supposed to, your AC is working overtime trying to maintain temperature. This will shorten the lifespan of your air conditioner.
• Clogged Air Filters. Clogged air filters, which can restrict airflow, are a simple but important issue to address. When filters are blocked, your system works harder to maintain desired temperatures, potentially shortening its lifespan.
• Uneven Cooling and Heating. This remains a top concern for many homeowners. This often points to problems with ductwork, fan motors, or even zoning setups. These repairs require professional expertise to identify the root cause and provide effective solutions.
• Fan Issues. The efficient cooling of your home or office depends on two fans within your AC system: one that removes heat and another that cools the circulating air via the evaporator coil. If these fans break down or malfunction – whether from poor lubrication, worn belts, dirt accumulation, or motor issues – your comfort suffers. A common problem is a condenser fan jammed by sludge-coated blades, usually due to a lack of maintenance. Also, physical blockages like fallen branches can stop the fan entirely.
• Clogged Condensate Drains. The moisture in your system goes through a drain line, into a pan, and then down a drain. If the pan gets full or the line gets clogged, water can back up into your system and cause severe damage. This can in turn cause moisture build-up on your walls, studs, and insulation which can cause mold growth, an entirely different and severe issue in itself.
• Broken Condenser Fan Motor. The motor powers the condenser fan’s blades, so if it is malfunctioning, the fan won’t blow hot air out of the condenser, and you won't hear it spinning. Causes of a broken fan motor include physical damage, capacitor issues, and for older systems, a loose or broken belt. Like the fan blades, a tree branch falling into the condenser can also damage the motor. Ignoring these issues can lead to compressor failure, which likely means it's the end of the road for your air conditioner.
