The short answer
We repair furnaces, heat pumps, ductless systems and wall heaters in Saratoga homes and secondary buildings. A visit follows a set order: confirm the symptom, test the system safely, explain the cause and options, then repair with your approval.
A Saratoga property can hold a surprising mix of heating equipment. The main house may run on a gas furnace or a heat pump, a newer addition might have its own ductless unit, and a guest cottage or converted studio could rely on a wall heater. When one of them stops producing heat on a cool, damp evening, you need someone who can work on all of it. Our technicians cover 95070 from our Los Altos base about 7 miles to the northwest, and this page walks through how a heating repair visit with us actually unfolds.
Step One: Pinning Down the Symptom
The technician starts by talking with you. Which area of the property is cold? Is there no heat at all, weak heat, heat that cycles on and off, or heat accompanied by noise or odor? When did it start, and has anything changed recently, such as a new thermostat, a power outage or remodeling work? Those answers often point straight at the system and component involved, and they keep us from replacing parts on a hunch.
Step Two: Testing the Equipment
Next we test the specific system. On a heat pump, that means checking heating mode separately from cooling, including the reversing valve, defrost controls, outdoor coil and any backup heat strips. On a gas furnace, we follow the ignition sequence from inducer to flame sensor to blower and read any fault code on the control board. On a ductless unit, we check the indoor head, its sensors and drain, along with the outdoor unit's refrigerant pressures and electrical readings.
Wall heaters get their own attention: pilot assembly, thermocouple, gas valve, burner condition and the clearance around the unit.
- Temperature rise across the furnace or air handler
- Refrigerant pressures and temperatures in heating mode
- Electrical readings on motors, capacitors and heat strips
- Thermostat signal at the equipment, not just at the wall
- Venting, draft and burner flame on gas appliances
Step Three: Explaining What We Found
Before any repair, you hear what failed, why it likely failed, and what the choices are. If there is a quick fix and a more thorough one, we describe both. If the equipment has a safety problem, such as a cracked heat exchanger, a blocked vent or a gas valve that will not close properly, we explain it clearly and leave the unit off until it is resolved.
Step Four: The Repair and a Final Check
Common repairs, such as igniters, flame sensors, capacitors, inducer motors, thermostats and drain lines, are usually completed on the first visit. Parts for less common equipment may have to be ordered, and we tell you how long that is likely to take and whether the system can run safely in the meantime. After the repair, we run a complete heating cycle, measure output, and confirm the room or zone that was cold is warming as it should.
Before leaving, the technician notes anything that is still working but showing wear, such as a weak capacitor, a corroded burner or a drain line starting to clog. Those items are not urgent, and we do not push them. Knowing about them lets you plan a fix before the next cold stretch instead of discovering them on a night when the heat suddenly stops. You also get a short explanation of the filter size and location for each system, which matters on properties where several units are spread across different buildings.
Ducts, Zones and Secondary Buildings
Some heating complaints in Saratoga homes have nothing to do with a broken heater. A zone damper stuck in one position can leave a wing of the house cold while the furnace runs normally. Crawlspace ducts can be torn or disconnected, sometimes by animals, and dump warm air under the floor. A guest house heated by an old wall unit may simply be too large for that heater. We check these causes alongside the equipment, because fixing the heater will not help if the warm air never reaches the room.
Thinking About the Next System
If your repair conversation turns into a replacement conversation, it helps to know the direction of local rules. Bay Area Air District Rule 9-4 sets a zero-NOx standard for gas furnaces manufactured from 2029, which in practice favors heat pumps at replacement time. The rule does not require replacing equipment that still works. For a cottage or addition heated by an aging wall unit, a ductless heat pump is often a practical upgrade when that unit finally gives out.
