CA Lic #1089826Free diagnosticWritten estimate before workSanta Clara shop serving Palo Alto
Furnace repair in Palo Alto, CA starts by identifying the heating system and the cause of the no-heat problem. EVS Mechanical serves gas furnaces, wall furnaces, and radiant-home boilers from its Santa Clara shop; call (408) 300-8254 for a free diagnostic and a written estimate before any work. Call to check no-heat appointment availability for your Palo Alto address.
What usually fails on the first cold night in Palo Alto?
The first cold snap can reveal a heating problem you did not notice while the system sat idle. A furnace may click without lighting, start and stop, or run its fan while the house stays cold. Ignition, flame-sensing, and airflow problems are possible causes. The sequence you observe helps the technician work toward the cause instead of choosing a part from the symptom alone. Palo Alto homes do not all heat the same way. A central gas furnace, a wall furnace, and an Eichler's radiant-slab boiler need different service questions. Tell EVS where heat normally enters the rooms. You do not need to know the equipment name to request help; warm floors, wall grilles, or central registers are useful starting details. Call (408) 300-8254 with your address and what the heater does. EVS provides a free diagnostic and a written estimate before any work. For Palo Alto no-heat calls, check appointment availability when booking. If there is a gas smell or a carbon monoxide alarm, leave the home and call 911 from outside before arranging equipment repair.
When to call about yours:
- The furnace clicks but never lights
- The heat starts, then stops before the house warms up
- The fan runs but the air stays cool
- The heater will not restart after power returns
- The boiler runs but the radiant floors no longer warm the rooms
Who this is for: Palo Alto homeowners and property managers with no heat, unreliable furnace starts, or uneven heating that needs a clear diagnosis.
Heating and cooling in Palo Alto homes
Greenmeadow and Green Gables: radiant heat changes the repair call
Palo Alto's Eichler tracts include Greenmeadow and Green Gables, with radiant tubing in concrete slabs and no original forced-air ductwork. When those floors stop heating, the equipment to identify is the boiler. A search for furnace repair can still bring you to the right service conversation if you explain that your home heats through the slab. Tell EVS whether all rooms lost heat or only one area. If a ductless system was added, explain whether that equipment still heats. You may have separate systems with separate faults. Start with the heat source you want restored, and keep any future cooling or conversion project as a separate discussion.
Professorville and Crescent Park: include the venting history
Older homes in Professorville and Crescent Park can have wall furnaces or earlier heating layouts tied to chimneys. A description written for a modern central furnace may miss what is actually in the house. Say where the heater sits and whether it serves one room or the whole home. Mention previous venting work or any known changes to the equipment. Leave internal inspection to the technician. If replacement becomes part of the discussion, the venting route needs its own assessment. Professorville's historic context can also matter when a proposed installation changes exterior equipment placement or roof penetrations; a repair call should establish the immediate heating fault first.
Older Craftsman homes: separate no heat from weak room airflow
Old Palo Alto and Barron Park include older wood-frame homes where attics and crawlspaces can accommodate ducts. If your home has a central furnace, tell EVS whether every register is cold or only certain rooms underperform. A weak bedroom register does not by itself establish that the furnace needs replacing. Point out changes after remodeling, duct work, or a thermostat replacement. If duct repair is recommended, ask which part of the air path needs attention and how it relates to your complaint. Avoid entering a crawlspace or disturbing old insulation to collect details. Room names and the history of the problem are enough to start the conversation.
City of Palo Alto Utilities: use the right utility information
City of Palo Alto Utilities supplies both electricity and natural gas in Palo Alto. If diagnosis leads to a replacement or heat-pump comparison, bring your own utility information. A neighboring city's program list does not establish what applies to your home. Ask about City of Palo Alto Utilities programs only as part of that separate planning discussion. Restoring a working heater and changing the heating source are different scopes. You should be able to read the repair findings before choosing whether to explore furnace installation in Palo Alto or a heat-pump conversion.
Service from the Santa Clara shop
EVS Mechanical serves Palo Alto from its shop at 3674 Bassett St in Santa Clara. Call to confirm availability for your address and explain any equipment access issues. Include entry instructions when booking. An appointment time and a completed repair are separate questions. Ask what the diagnostic visit will establish and how EVS will communicate the next step if a part needs ordering.
What you get from an EVS repair visit
Your actual heating system comes first.
Gas furnaces, wall furnaces, and radiant-home boilers need different diagnostic paths. You can explain how your house heats without knowing the failed part or being ready to choose new equipment.
Written estimate before any work.
Read the proposed repair scope and ask questions before approving it. If replacement is worth considering, request the findings behind that advice and review its scope separately.
Owner-operated service.
EVS is an owner-operated, multi-brand shop. You have a company contact for the repair discussion and follow-up rather than needing to sort out a heating problem through a sales pitch.
Older-home context.
Palo Alto's wall-furnace, central-furnace, and radiant layouts need attention to the house as well as the heater. Describe any access limits or previous work when booking so those details become part of the visit.
Make the Repair Decision with the Findings in Front of You
You should understand the proposed work before approving a heating repair. Ask how each finding relates to your symptom. Have any remaining comfort problem explained separately.

Call (408) 300-8254 and describe what happens when your Palo Alto home calls for heat.
From first call to finished job
Describe what stopped working
Say whether the heater does nothing, clicks without starting, or starts and stops. Mention any visible display message and whether other rooms still have heat. Include a recent power interruption or control change. Share the model number only if the label is accessible without opening the equipment.
Get the free diagnostic
The technician checks the reported heating fault on your system and explains the findings. For an intermittent failure, your record of when it happens helps. Do not keep resetting the equipment to recreate a fault. Save what you observed so the visit begins with a useful account of the problem.
Review the written estimate before any work
Ask what the proposed repair addresses, whether the needed parts are available, and what happens next if work requires another visit. If the findings raise a replacement question, request a separate scope. You can compare the options without treating every no-heat symptom as proof that the whole system has failed.
Approve work and review operation
After the approved repair, ask what was done, what normal operation looks like, and what to watch for. Keep the repair information for follow-up if the symptom returns.
Plan for the next heating season
Bring unresolved start-up trouble or uneven heating to a [preventive maintenance](/services/preventive-maintenance) visit before regular winter use. Mention what happened during the first cold snap. Maintenance and repair serve different needs; a heater that still fails to start needs its fault explained rather than only a seasonal checklist.

“EVS Mechanical made what could have been a stressful process incredibly smooth. They diagnosed and repaired our HVAC system quickly and got everything running again. They didn't just do the work — they made sure we understood what was happening and why. Honest pricing. They didn't try to upsell us on things we didn't need. Really appreciated that they were on time and ready to work. If you need HVAC work done right, call EVS Mechanical. You won't be disappointed.”

“The EVS Mechanical team were great! The EVS team showed up on time and completed the heat pump installation in one day as promised. Axel stayed on top of the whole process from quote to final inspection and communication was awesome. EVS made the whole process seamless. The pricing was more than fair for the quality of work we received. Every person on the crew was courteous and professional. When the installation was finished I couldn't tell they had been in the house. Thanks to EVS Mechanical we have heating and air conditioning again making for a comfortable house. I strongly recommend EVS Mechanical for all your HVAC needs.”

Frequently Asked Questions
Call EVS Mechanical at (408) 300-8254 for furnace repair in Palo Alto. Describe the symptom and whether you have a central furnace, wall furnace, or radiant-floor boiler. EVS serves Palo Alto from its Santa Clara shop and provides a free diagnostic and a written estimate before any work. Check appointment availability for your address when booking.
Yes. For heater repair in Palo Alto, tell EVS if your home heats through a radiant slab. That points the service request toward the boiler rather than an assumed forced-air furnace. If you also have a mini-split, explain which heat source stopped working and which rooms are affected.
If there is no gas smell or other emergency, check the thermostat heat setting and an accessible filter using the owner's instructions. Note any outage and visible fault message. Leave gas, ignition, and internal electrical checks to a technician.
No single symptom settles repair versus replacement. Tell EVS how the furnace starts, when it stops, and whether the fan keeps running. Ask the technician to explain the diagnostic findings before you approve work. If replacement deserves comparison, the written scope should show why it addresses the problem.
The answer depends on the fault and required parts. Confirm the appointment when booking and ask about the repair plan after diagnosis. A useful service visit explains what is needed and the next step if work cannot be completed then. An arrival appointment alone cannot establish when heat will be restored.
EVS offers a free diagnostic and a written estimate before any work. The findings determine the proposed repair scope. Review that scope and ask any questions before approving the work.
