That’s why every Brandt HVAC technician is background-checked and identity-verified through our Threshold Verified standard. We send you their name and photo before arrival, and they show a photo ID badge at your door. If anyone arrives who you weren’t told to expect, that visit is on us.
Our 365-Day Done Right Promise covers every repair we make. If a repair fails within that year, we return at no charge. No argument, no additional fee. Every job also starts with a written, itemized price that you approve before we touch a tool. We’ve operated this way since 2003 as part of the Threshold Group family, and each location is independently owned and operated.

Our technicians are not paid commission on what they sell, so the recommendation you get is based on what your house actually needs.
Gas Furnace Repair in Mountain View
Gas Furnace Repair in Mountain View covers the full range of forced-air heating problems: burners that won’t ignite, heat exchangers with dangerous cracks, blower motors that hum but don’t spin, and gas valves that fail to open. Because Mountain View’s post-WWII tract homes were often built with single-zone systems and undersized ductwork, we frequently find that the “furnace problem” is actually a distribution problem, ducts leaking into crawl spaces or attics that were never properly sealed.
A standard gas furnace repair in Mountain View runs $150 – $700, depending on the part and the time required. Simple ignitor replacements sit at the lower end. Heat exchanger work or gas valve replacement trends higher. We always provide a written price before starting.
When the Ducts Are the Real Problem
We’ve opened too many utility closets in Mountain View to count, and sometimes the furnace itself is fine. The real issue is original ductwork from the 1960s with seams that have separated, or flex duct that has collapsed in a tight crawl space. We pressure-test the duct system and show you the numbers. If sealing or partial replacement makes more sense than a new furnace, we’ll say so directly.
Heat Exchanger Safety Checks
A cracked heat exchanger can leak carbon monoxide into your living space. During any gas furnace repair, we inspect the exchanger with a camera and combustion analyzer. If we find a crack, we show you the image and explain your options. This is not a repair we patch and walk away from; replacement is the only safe path.
Furnace Tune Up in Mountain View
Furnace Tune Up in Mountain View is preventive maintenance designed to catch problems before your heat fails on the coldest night of the year. Our tune-up includes combustion analysis, safety control testing, blower motor amp draw, gas pressure verification, and a full heat exchanger inspection. We also check your filter condition and airflow across the coil. In Mountain View’s older homes, we pay special attention to static pressure, because undersized or leaky original ductwork forces your furnace to work harder than it should, shortening its life and spiking your gas bill.
A furnace tune-up in Mountain View costs $80 – $200. We schedule these year-round, though September through November fills fastest. You’ll receive a written report of everything we found, with photos if we spot a concern.
What We Find in Older Mountain View Systems
Many furnaces we tune up in Mountain View are 20-plus years old, paired with ductwork that was never designed for modern airflow requirements. We measure temperature rise and static pressure, then explain whether your system is operating within manufacturer specs. Sometimes the fix is a simple blower adjustment. Sometimes the ductwork needs attention before any new equipment will perform properly.
Carbon Monoxide and Safety Controls
Every tune-up includes testing of the flame rollout switch, limit switch, and carbon monoxide levels in the flue and ambient air. Mountain View’s tightly sealed Eichler homes and older tract houses with retrofitted weatherstripping can create negative pressure issues that affect combustion. We verify that your furnace is drafting safely and that all safety shutoffs function as designed.
Trusted Brands We Service in Mountain View
We repair Goodman, Rheem, York, and Daikin furnaces regularly in Mountain View, and we stock common ignitors, blower motors, and control boards for fast turnaround. Our technicians also service Carrier, Trane, Lennox, Bryant, and American Standard.

If your furnace is no longer supported by the factory, we’ll tell you honestly and explain your replacement options with fixed pricing.
Common Furnace Repair Problems We See in Mountain View Homes
- Failed ignitors in original 1960s furnaces. The silicon carbide ignitors in older Goodman and Rheem units crack after repeated thermal cycling. We see this constantly in Monta Loma and the tract homes off Middlefield Road. Replacement takes about an hour, and we carry the part on every truck.
- Blower motors straining against collapsed flex duct. Mountain View’s crawl spaces are tight, and original flex duct often gets crushed or disconnected. The blower motor overheats and fails. We replace the motor, but we also find and fix the duct restriction so it doesn’t happen again.
- Boiler short-cycling mistaken for furnace failure. In Mountain View’s Eichler tracts, what the homeowner calls a “furnace problem” is often a hydronic boiler with a failed circulator pump or expansion tank. We pressure-test the loops and thermal-image the slab to find the real source.
- Upstairs bedrooms that never reach temperature. Single-zone systems in two-story Mountain View homes, especially near Cuesta Park and the older sections of Los Altos border, can’t balance heat between floors. The furnace runs constantly while the thermostat reads 72 downstairs and 62 upstairs. We diagnose whether it’s a blower issue, duct design, or simply a system that was never sized for the load.

FAQs About Furnace Repair in Mountain View
Because the original system was probably never sized with a proper load calculation, and the ductwork has likely deteriorated. A like-for-like swap gives you a new furnace with the same old problems: leaky ducts, poor airflow, and uneven heating. We measure your home’s actual heat loss and duct capacity first. If your ducts are too small or too leaky, a new furnace will short-cycle, run inefficiently, and fail prematurely. Call (984) 538-9003 and we’ll show you the numbers.
Exactly right, and this is common in Mountain View. Your “furnace” is actually a hydronic boiler or electric radiant manifold serving loops buried in the concrete slab. We service those systems too. Diagnosing a cold zone means pressure-testing the embedded tubing or thermal-imaging the floor to find a break or blockage. We got a call from a homeowner on Fairchild Drive in the Eichler tract near Monta Loma whose 1960s addition had gone cold while the rest of the slab stayed warm; instead of a furnace, we found the original hydronic boiler short-cycling and one zone loop losing pressure through embedded tubing. We thermal-imaged the floor, confirmed the failed loop, rebalanced the manifold, and serviced the boiler’s circulator and expansion tank so the loop held pressure again. No new furnace was ever going to fix that house. Call us at (984) 538-9003 and we’ll diagnose what you actually have.
Maybe, but often it’s a single-zone design problem. In many Mountain View homes, especially two-story tract houses near Cuesta Park, one thermostat downstairs controls heat for the entire house. The furnace runs until the downstairs is satisfied, while upstairs bedrooms stay cold. We check whether the blower motor is moving enough air, whether dampers are stuck, and whether the duct design can even support the airflow needed. Sometimes the fix is a zoning retrofit or duct modification, not a bigger furnace. Call (984) 538-9003 for a free evaluation.
Not for most repairs, but possibly for replacement or conversion. Many older Mountain View homes still have 100-amp panels, and modern furnaces, heat pumps, or mini-split systems often require more capacity. We evaluate your panel as part of any replacement quote and coordinate with a licensed electrician if an upgrade is needed. We won’t install equipment that your electrical system cannot support safely. Call (984) 538-9003 and we’ll assess your specific situation.
Most furnace repairs in Mountain View run $150 – $700, with furnace tune-ups at $80 – $200. Simple ignitor or flame sensor replacements are at the lower end. Heat exchanger work, gas valve replacement, or jobs requiring extensive duct access trend higher. We provide a written, fixed price before any work begins, and every repair is covered by our 365-Day Done Right Promise. Call (984) 538-9003 for a free estimate.
