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 severely impact your AC’s performance, leading to poor cooling and potential damage to the system. CPI Service uses advanced leak detection methods to swiftly locate and repair refrigerant leaks, restoring full efficiency and keeping your home cool and comfortable in Los Gatos.
- Dirty or Clogged Filters: Clogged filters are a primary cause of reduced AC performance and higher energy bills. When filters are blocked with dirt and debris, airflow is restricted, forcing your system to work harder. Regular filter replacements improve airflow, reduce strain on your system, lower energy costs, and maintain a consistent indoor temperature.
- Thermostat Issues: Faulty thermostats, whether from poor calibration or outdated technology, can disrupt temperature control, leading to uneven cooling. CPI Service offers thermostat recalibration and modern smart thermostat upgrades, ensuring accurate temperature regulation and improving energy efficiency across your home or business.

Our skilled HVAC technicians specialize in diagnosing and fixing electrical problems quickly, restoring your system’s functionality and preventing future breakdowns to extend your AC’s lifespan.

Our HVAC technicians cleaning service at CPI Service removes dirt and blockages from the coils, enhancing efficiency and preventing future issues.

Frequently Asked Questions from Los Gatos Residents for AC Service
How to Find an AC Refrigerant Leak?
To find an AC refrigerant leak, visually inspect the refrigerant lines, coils, and connections for any oily residue, as refrigerant carries oil that leaves stains. You may also hear a hissing sound near the evaporator or condenser, which could indicate gas escaping. A common method is to apply a soap-and-water solution to the refrigerant lines; bubbles will form where the leak is. However, refrigerant leaks should be handled by a licensed HVAC technician, as they require specialized tools and knowledge for accurate detection and repair.
What Are the Signs Your AC Needs Repair?
Signs that your AC needs repair include blowing warm air, weak airflow, or unusual noises like grinding or buzzing. Frequent short cycling, foul odors, water leaks, or higher energy bills can also indicate issues. If you notice any of these symptoms, it is important to contact a certified HVAC technician to diagnose and fix the problem, ensuring your system operates efficiently again.
