The short answer
We repair every common home heating type in Mountain View, including gas furnaces, wall and floor furnaces, heat pumps and ductless systems. Our technicians identify the system, test it under operation and fix the actual failed part rather than guessing.
Not every house in Mountain View heats the same way. Some have a central gas furnace pushing air through attic ducts, some still rely on a wall heater in the hallway, a few older homes have a floor furnace under a grille in the living room, and a growing number now run heat pumps or ductless heads. Each type fails in its own way, and the fix depends on knowing which one you have. ExpertFlow HVAC Repair Service drives about three miles north from our Los Altos base to repair heating systems in 94040, 94041 and 94043. Use the sections below to identify your system and the problems it tends to develop.
First, which heating system do you have?
If you are not sure, a quick look usually tells you. Knowing the type before you call lets us bring the right parts and gives you a sense of what might be wrong.
- Registers in floors or ceilings plus a cabinet in a closet, garage or attic: central forced-air furnace
- A single metal grille set into the floor, often in a hallway or living room: floor furnace
- A grille mounted in an interior wall with no ducts elsewhere: wall furnace or wall heater
- An outdoor unit that runs in winter as well as summer: heat pump
- Slim white units high on walls or set in ceilings: ductless mini-split
Wall and floor furnaces in older homes
Floor and wall furnaces are simple appliances, but many of the ones still in service are quite old. Typical issues include a pilot that will not stay lit because of a worn thermocouple, a gas valve that sticks, a clogged burner, or a vent connection that has rusted. Because these units sit right in living space, combustion safety matters a great deal.
We clean, adjust and repair them where parts are still available and the unit is in safe condition. When a floor or wall furnace is beyond repair, we can discuss replacement options, including ductless heat pumps that fit into similar spaces without major construction.
Central furnaces and duct-related complaints
A forced-air system can be working perfectly at the furnace and still leave rooms cold. Disconnected or crushed ducts in the attic, closed or blocked registers, and undersized returns all reduce the heat that reaches the far end of the house. We check the furnace itself first, then measure airflow and temperatures at several registers to see whether the problem is the equipment or the distribution.
On the furnace side, worn igniters, dirty flame sensors, failing inducer motors and stuck limit switches account for most no-heat calls. Our technicians test each part of the sequence before replacing anything.
Heat pumps and ductless systems in heating mode
Heat pumps are increasingly common in Mountain View, and winter service calls for them follow a different pattern. A unit covered in frost that never clears may have a faulty defrost control or sensor. Lukewarm air can mean low refrigerant from a leak or a reversing valve that is not shifting fully. Auxiliary electric heat strips that run constantly will raise utility bills and usually signal that the heat pump itself is underperforming.
For ductless systems, we check indoor heads for dirty filters and coils, confirm communication between the indoor and outdoor units, and review error codes. Many of these faults are corrected in one visit.
Damp winters and what they do to equipment
Mountain View winters are mild but damp. Moisture finds its way into outdoor electrical connections, rusts the vents of older appliances, and can make drain lines on high-efficiency furnaces sluggish. Short, intermittent heating demand also means problems can hide for weeks before a cold night exposes them. If you notice a new smell, a sound you have not heard before or a change in how long the system runs, an early check is easier than a no-heat call later.
When a repair is not sensible, the Bay Area Air District rules for gas furnaces may affect your next choice, but they do not require replacing working equipment. We also repair heating systems in Sunnyvale, Palo Alto, Los Altos Hills, East Palo Alto and Cupertino.
