What Do Our Clients Say About Furnace Services in Los Gatos?
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 in your home feel colder than others, your furnace may be struggling with restricted airflow, clogged air filters, or improperly balanced ductwork. Sometimes, a furnace blowing cold air is a sign of a more serious issue. These problems can lead to uncomfortable temperatures and higher energy bills, as your system has to work harder to heat your home.
Strange Noises:
Unusual noises like banging, screeching, or humming coming from your furnace could be a sign of mechanical issues such as loose parts, worn-out belts, or a malfunctioning blower motor. These sounds are common during the first startup of the season but should not be ignored, as they can lead to further damage if not addressed promptly.
Weak Airflow:
Weak airflow from your vents could be caused by a failing blower motor, clogged filter, or blocked ductwork, common in older homes or those with complex systems. This issue can lead to uneven heating and difficulty maintaining a comfortable temperature. If your furnace is not turning on or struggling, the blower motor may need attention.
Frequent On-Off Cycling:
If your furnace turns on and off too frequently, this could be a sign of short cycling. Causes include a miscalibrated thermostat, a dirty flame sensor, or issues with the furnace control board. In some cases, a furnace pressure switch might be stuck open, causing this problem. Short cycling not only increases energy costs but also reduces the lifespan of your furnace.
If you are experiencing uneven heating, strange noises, weak airflow, or frequent on-off cycling, CPI Service can help in Los Gatos. Our licensed HVAC technicians specialize in diagnosing and repairing issues like faulty blower motors, control board malfunctions, or pressure switch errors. We are here to keep your furnace running efficiently and your home comfortable year-round.
