What Our Clients Say About Us in Fremont?

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.

Ron K.

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!

Allan Huynh

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. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

San Jose HVAC FAQs

What is HVAC, and How Does It Work?

HVAC stands for Heating, Ventilation, and Air Conditioning, and it controls indoor temperature, air quality, and humidity. The system works by drawing in air, conditioning it through heating or cooling components, and circulating it through ducts or vents.

How often should I have my HVAC system serviced in Fremont?

HVAC systems in Fremont should be professionally serviced at least once a year. For optimal performance, it is recommended to schedule AC maintenance in spring and conduct heating checks in fall. Regular servicing helps prevent breakdowns, improves efficiency, and extends system life.

What is the best HVAC system for Fremont's climate?

The best HVAC system for Fremont’s mild to warm climate is a high-efficiency heat pump or a dual-fuel system. These units offer both heating and cooling in one, making them ideal for year-round use. Zoned mini-split systems are also popular for flexible, ductless comfort in Fremont homes.

How can I improve the energy efficiency of my HVAC system?

You can improve HVAC efficiency by replacing filters regularly, sealing duct leaks, installing a programmable thermostat, and scheduling routine maintenance. In Fremont, where temperatures vary seasonally, these steps help reduce energy use and keep utility bills under control.

What signs indicate that my HVAC system needs repair?

Common signs that indicate that your HVAC system needs repair include unusual noises, uneven temperatures, weak airflow, frequent cycling, and rising energy bills. Fremont property owners should also look for moisture buildup or poor air quality, which may point to internal system problems.

What is the average cost for HVAC installation in Fremont?

Do I need a permit to replace my HVAC system in Fremont?

Yes, you will need a permit to replace an HVAC system in Fremont. Local codes mandate that any major HVAC replacement must comply with California energy standards and be inspected upon completion. Your contractor should handle the permitting process as part of the installation.
