Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time.

Air Conditioning Issues We Expertly Resolve
- AC Refrigerant Leaks: Refrigerant leaks can significantly reduce your AC’s performance, causing insufficient cooling and potentially leading to system damage. At CPI Service, we use advanced leak detection tools to quickly locate and repair refrigerant leaks, restoring optimal efficiency and ensuring your home stays cool and comfortable in Santa Clara.
- Dirty or Clogged Filters: Clogged filters are a major factor behind poor AC performance and rising energy bills. When filters are blocked with dirt and debris, airflow is restricted, causing your system to work harder. Regularly replacing filters enhances airflow, reduces strain on your system, lowers energy costs, and helps maintain a consistent indoor temperature.
- Thermostat Issues: Faulty thermostats, whether due to poor calibration or outdated technology, can disrupt temperature control and lead to uneven cooling. CPI Service offers thermostat recalibration and upgrades to modern smart thermostats, ensuring accurate temperature regulation and maximizing energy efficiency throughout your home or business.
- Electrical Control Failures: Electrical issues, such as faulty capacitors or short cycling, can cause your AC to malfunction and may result in expensive repairs. Our HVAC technicians are experts in diagnosing and repairing electrical problems swiftly, restoring your system’s function and preventing future breakdowns to extend the life of your AC.
- Frozen Evaporator Coils: Frozen evaporator coils typically indicate airflow restrictions or low refrigerant levels, both of which prevent your AC from cooling effectively. In Santa Clara, CPI Service resolves this issue with thorough coil cleaning and refrigerant checks, bringing your system back to full capacity and ensuring efficient cooling.
- Dirty Condenser Coils: When condenser coils accumulate dirt and debris, they lose their ability to expel heat effectively, causing your system to overheat and consume more energy. Our expert cleaning services at CPI Service remove dirt and blockages from your condenser coils, boosting efficiency and reducing the risk of future complications.
Drainage Problems: Clogged or malfunctioning condensate drain lines can cause water buildup within your AC unit, potentially leading to leaks and water damage. CPI Service clears and maintains drain lines to ensure proper water flow and avoid system malfunctions, keeping your home dry and your system running smoothly.

Frequently Asked Questions from Santa Clara Residents for AC Service
How to Find an AC Refrigerant Leak?
To find an AC refrigerant leak, start by inspecting the refrigerant lines, coils, and joints for any oily residue, as refrigerant carries oil that leaves stains. Listen for a hissing sound near the evaporator or condenser, which may indicate gas escaping. You can also apply a soap-and-water solution to exposed refrigerant lines; bubbles will form at the leak site. However, detecting and repairing refrigerant leaks should be handled by a licensed HVAC technician, as it requires specialized tools and adherence to safety regulations.
What Are the Signs Your AC Needs Repair?
Signs that your AC needs repair include blowing warm air, weak airflow, strange noises (like grinding or banging), or an inability to cool rooms effectively. Other indicators include frequent short cycling, unusual odors, or increased humidity indoors. If your system is leaking water or your energy bills rise unexpectedly without a change in usage, it is a sign that your AC needs attention. Prompt repair can help prevent further damage and restore efficient cooling.
How Often Should AC Be Serviced in Santa Clara?
In Santa Clara, it is recommended to have your AC serviced at least once a year, ideally before the warmer months. The region experiences hot summers and mild winters, which puts seasonal strain on your AC system.
