What Do Our Clients Say About Furnace Services in Santa Clara?
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.

Common Signs That Your Furnace Needs Repair
Uneven Heating:
If certain rooms feel much colder than others, your furnace could be facing issues like restricted airflow, clogged air filters, malfunctioning zone controls, or poorly balanced ductwork. These problems are often seen in older or multi-level homes in Santa Clara, where airflow distribution has not been updated. Uneven heating causes additional strain on your system, leading to inconsistent comfort and higher energy consumption.
Strange Noises:
Unusual sounds, such as banging, screeching, or humming, coming from your furnace could indicate mechanical problems, like loose parts, worn-out belts, or ignition failures. In Santa Clara, such sounds are common during the first startup of the season, after months of inactivity. Addressing these noises early on can prevent more severe damage, saving you from costly repairs.
Weak Airflow:
Low air pressure from your vents might be caused by a failing blower motor, a dirty filter, or blocked ductwork. This issue is especially common in multi-level or older Santa Clara homes, where weak airflow can create hot and cold spots, reducing overall efficiency. Resolving airflow problems early prevents strain on your furnace and keeps it running smoothly.
Frequent On-Off Cycling:
If your furnace turns on and off repeatedly, this may signal a miscalibrated thermostat, a dirty flame sensor, or airflow blockages. Known as short cycling, this issue not only increases energy bills but also reduces the lifespan of your furnace. In Santa Clara’s moderate climate, many homeowners overlook short cycling until it leads to a complete system failure.
If you are noticing uneven heating, strange noises, weak airflow, or frequent on-off cycling in your Santa Clara home, CPI Service has the expertise to resolve these issues quickly. Our certified HVAC technicians are trained to diagnose airflow restrictions, fix mechanical issues, replace worn parts, and recalibrate thermostats to restore your furnace’s efficiency.

Frequently Asked Questions from Santa Clara Residents for Furnace Service
How Often Should a Furnace Be Serviced in Santa Clara?
A furnace in Santa Clara, whether gas or electric, should be serviced at least once a year, typically before the start of the colder months. Regular annual servicing ensures optimal performance, improves energy efficiency, and helps prevent unexpected breakdowns. For gas furnaces, this includes checking for gas leaks and ensuring safe combustion, while for electric furnaces, it involves inspecting electrical components and connections. For older furnaces or those in heavy use, bi-annual servicing is beneficial.
How to Service an Oil Furnace?
To service an oil furnace, start by turning off the power and fuel supply. Replace or clean the oil filter, inspect the oil tank for leaks, and check fuel levels. Clean the burner and check the oil pump for proper fuel delivery. Ensure the heat exchanger, flue pipe, and air filters are clean for optimal airflow. Test the thermostat and verify the system’s operation. Regular servicing enhances efficiency and safety, with more frequent checks recommended for older systems.
How Long Does a Furnace Installation Take?
A furnace installation typically takes 4 to 8 hours, depending on factors such as the type of furnace, the complexity of the installation, and whether any existing ductwork needs to be modified. For more complex installations, such as upgrading from a different heating system or installing a larger furnace, the process could take longer, sometimes up to a full day. It is important to allow time for a professional HVAC technician to ensure everything is properly connected, tested, and running efficiently.
How Much Does It Cost to Install a New Furnace in Santa Clara?
The cost to install a new furnace in Santa Clara ranges from $4,000 to $15,000+. The price depends on several factors, including the type of furnace (gas, electric, or oil), the size of your home, the complexity of the installation, and any additional work needed, such as upgrading ductwork or installing a new thermostat.
