Heating Repair for Homes in Los Gatos

The short answer

Heating repair in Los Gatos starts with the symptom: no heat, uneven rooms, strange noises or smells, short cycling or rising bills. Each pattern points to a likely cause in furnaces, wall heaters, floor furnaces, heat pumps or ductless systems, which a technician then confirms by testing.

Homes in Los Gatos are heated by an unusually mixed set of equipment. Older houses near the center of town may still rely on a gas wall heater or a floor furnace, many mid-century homes have a central furnace in the attic or garage, and recent remodels often add a heat pump or ductless units. EliteAir Heating & Cooling repairs all of these across 95030 and 95032, sending technicians about 7 miles south from San Jose. Rather than sorting by equipment, this page is organized around what you notice in the house, because that is usually where a homeowner starts, and it often points straight at the cause.

No heat at all

When nothing happens at the thermostat, the cause is often simpler than it seems. Dead thermostat batteries, a tripped breaker, a service switch turned off near the furnace or a furnace door not fully latched can each keep the system from starting. If those check out, the likely suspects are an igniter that has cracked, a pilot on a wall heater that will not stay lit, a failed draft inducer or a control board fault.

On a heat pump, a system that runs outdoors but delivers no warmth may have a reversing valve stuck in cooling mode, low refrigerant or a thermostat configured incorrectly after a replacement.

Some rooms warm, others cold

Uneven heat is one of the most common complaints in older Los Gatos homes. Ducts installed decades ago may be undersized, poorly sealed or disconnected in the attic, and additions are frequently tied into a system never designed to serve them. In houses heated by a single wall or floor furnace, back bedrooms are simply too far from the heat source.

We measure supply temperature and airflow at the registers to see where heat is being lost. Fixes range from sealing and reconnecting ducts to rebalancing dampers or adding a ductless zone for a room the central system cannot reach.

Noises and smells worth acting on

Some sounds and odors are normal; a faint dusty smell on the first cold day of the season usually burns off within an hour. Others signal trouble:

  • A loud bang when burners light, which can indicate delayed ignition
  • Squealing or grinding from the blower, often a worn bearing or belt
  • Rattling from the cabinet or ducts, from loose panels or a failing inducer motor
  • A burning electrical smell, which means turning the system off right away
  • A rotten egg odor, which means leaving the home and contacting the gas utility from outside
  • A sharp chemical or exhaust smell near a wall heater or floor furnace, which calls for shutting it off until it is inspected

Short cycling and climbing bills

A system that starts and stops every few minutes is working inefficiently and wearing itself out. In furnaces, short cycling often comes from an overheating heat exchanger caused by a clogged filter or closed registers, a dirty flame sensor, or a thermostat placed near a heat source. In heat pumps, it may point to oversizing, refrigerant problems or a defrost control fault.

Rising bills with no change in comfort tell a similar story. Heat pumps leaning too heavily on backup heat strips, furnaces running long cycles because of leaky ducts, and worn blower motors drawing extra power all show up first on the bill.

Repair or replace, and the rules that apply

Most heating problems are repairable, and Bay Area Air District rules do not require replacing working equipment. They apply only when an existing furnace or water heater fails or is replaced. The rule to know is Rule 9-4: natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard, which in practice points replacements toward heat pumps.

For an older wall heater or furnace needing a significant repair, we explain what the repair gets you and what switching to a heat pump would involve. BayREN and your local clean energy provider list current incentives, which change by funding cycle, and we confirm the active offer before quoting it.

Along with Los Gatos, we repair heating systems in Monte Sereno, Campbell, Saratoga, Cupertino and Santa Clara.

What to expect

How a visit goes

  1. Measure first

    Temperatures, pressures, electrical readings and airflow come before any recommendation, so the fix addresses the actual fault.

  2. Show and explain

    We point out failed parts or readings, describe what they mean, and answer questions until the choice makes sense to you.

  3. Respect the home

    Floor protection, careful attic and closet work, and a cleaned-up space before we leave are standard on every visit.

FAQ

Common questions

Don’t see your question? Call (669) 201-9530 and we’ll talk it through.

Do you repair gas wall heaters and floor furnaces?

Yes. We repair pilots, thermocouples, gas valves and controls on wall and floor furnaces and check their venting and combustion for safety.

Why does my house smell dusty when the heat first comes on?

Dust settles on the heat exchanger or heat strips during the warm months and burns off on first use. If the smell lasts more than an hour or smells electrical, turn the system off.

Why are my back bedrooms always cold?

Usually it is duct trouble, such as leaks, disconnections or undersized runs, or the rooms are simply far from a single heat source. Ductless zones are one solution.

What causes a furnace to turn on and off constantly?

Common causes are a clogged filter, a dirty flame sensor, a poorly placed thermostat or an overheating heat exchanger. A technician can test each one.

My heat pump bills went up this winter. Why?

The system may be relying on backup heat strips more than it should because of a refrigerant, defrost or thermostat setting problem. A diagnosis can pinpoint it.

Should I replace an old wall heater with a heat pump?

It is worth considering if repairs are adding up, and ductless heat pumps suit homes without ducts. Working equipment does not have to be replaced under Air District rules.
