Why Meadowsweet Heating & Air Is Pleasanton’s Preferred Furnace Repair Company
We’re not the biggest HVAC company in the Bay Area, and we’re fine with that. We built our reputation in Pleasanton one call at a time, dealing with the specific issues that show up in this valley’s housing stock: cracked heat exchangers from undersized returns, blower motors burnt out from high static pressure, and thermostats confused by 30-degree overnight swings. Luis Serrano and our furnace team have walked through enough Birdland and Vintage Hills two-stories to know the difference between an equipment failure and a duct problem before we even pull the panel.
Every visit includes the Cedarwell Care Promise. That means a background-checked, uniformed technician, a written price before any work starts, shoe covers and drop cloths inside your home, and a photo of the clean-up sent before we leave. If something isn’t done right, our 365-Day Done Right Promise means we make it right. No runarounds, no fine print. Families in Pleasanton with kids and pets shouldn’t have to choose between a warm house and a clean playroom floor.
We answer the phone live, 24 hours a day, 7 days a week. Nights, weekends, holidays. No voicemail queue. When your furnace quits at 11 p.m. and the baby’s room is dropping below 65°F, you talk to a person who can dispatch a truck to your Pleasanton neighborhood, not an answering service.
Boiler Repair in Pleasanton
Boiler Repair in Pleasanton covers hydronic heating systems that circulate hot water through radiators, baseboards, or in-floor tubing, and we see these most often in older custom homes and a handful of mid-century builds scattered through the downtown core and along First Street. A typical boiler repair in Pleasanton runs $150-$700, with circulation pump failures, zone valve replacements, and expansion tank swaps being the most common jobs. When a boiler loses pressure or a zone stops heating while others stay warm, the problem is usually mechanical rather than combustion-related.
Circulation and Zone Valve Diagnostics
Boilers in Pleasanton homes with multiple zones can develop uneven heating when an aging circulator pump no longer moves water at the designed flow rate. We trace the pressure differential across the loop, confirm which zone valve is stuck, and replace only what actually failed. That keeps the repair cost at the lower end of the range instead of replacing components that still have years left.
Expansion Tank and Pressure Relief Checks
A waterlogged expansion tank or a pressure relief valve that drips constantly is a straightforward fix most Pleasanton homeowners don’t need to live with. We test the air charge on the tank, verify the fill valve’s set pressure, and make sure the system isn’t cycling into unsafe territory. It’s the kind of quiet, specific work that prevents a small leak from turning into a soaked floor or a failed heat exchanger.
Gas Furnace Repair in Pleasanton
Gas Furnace Repair in Pleasanton is our most common winter service call, and the vast majority of these systems are forced-air units tied to ductwork that was installed when the home was built. A gas furnace repair in Pleasanton typically lands between $150 and $700, depending on whether the failure is an ignitor, a flame sensor, a gas valve, a blower motor, or the heat exchanger itself. The first thing we do on any call is verify gas pressure at the manifold and check for proper combustion, because safety comes before any parts get replaced. If we find a cracked heat exchanger, we shut the system down and give you a clear written quote for repair or replacement before we leave.
Ignitor and Flame Sensor Replacement
When a gas furnace clicks but won’t light, the ignitor is usually the culprit, especially on systems that have been cycling hard through cold Pleasanton winter mornings. A failing flame sensor causes the opposite problem: the burners light, then shut off seconds later because the control board can’t confirm flame. Both are straightforward repairs in the $150-$350 range on most furnace brands we service, including Goodman, Rheem, and York.
Gas Valve and Safety Circuit Testing
Furnaces in Pleasanton homes built between 1987 and 2005 are now seeing gas valve failures from age and from years of running against restricted airflow. We test the valve’s inlet and outlet pressure with a manometer, verify the rollout and limit switches are working, and inspect the flue for proper draft. If the gas valve is failing intermittently, we’d rather catch it at the first call than have your family wake up cold because the valve stopped opening altogether.
Trusted Brands We Service in Pleasanton
We service equipment from nine major manufacturers, and for Pleasanton furnace repairs, we most often see Goodman, Rheem, York, and Daikin units in the field. Because so many Pleasanton tract homes were built with builder-grade Goodman or York furnaces, we keep the most common ignitors, flame sensors, pressure switches, fan motors, and capacitors stocked on our trucks for same-day service. Daikin and Rheem systems show up more in newer construction and recent replacements. Whatever brand your furnace is, our technicians train on its specific sequence of operation, not a generic one-size-fits-all checklist.
Common Furnace Repair Problems We See in Pleasanton Homes
- Blower motors burned out from high static pressure. The original return ducts in many 1987-2005 Pleasanton tract homes are too small for the airflow a furnace needs, which overheats the blower motor and shortens its life. A motor replacement is a $250-$500 fix, but without addressing the duct problem, the new motor will fail again.
- Heat exchangers cracked by restricted airflow. When the blower can’t move enough air through the system, the heat exchanger runs hotter than it was designed for. Over years of winters in the Amador Valley, that stress causes cracks, and a cracked heat exchanger releases carbon monoxide into the home. This is not a DIY inspection, and if we find one, we shut the system down immediately.
- Shoulder-season thermostat and staging confusion. Pleasanton’s 30-40°F overnight valley swing in spring and fall makes basic single-stage thermostats cycle strangely. The furnace short-cycles, or the blower runs when it shouldn’t, and the homeowner thinks the gas valve failed. Often the fix is recalibration or a proper staging thermostat, not a major part.
- Furnaces and AC condensing units aging out together. Homes built in the late 1980s through early 2000s often still have their original furnace and R-22 condensing unit. A repair call for a “furnace problem” sometimes reveals that the paired system’s age, refrigerant type, and efficiency make a coordinated replacement the more honest recommendation.

FAQs About Furnace Repair in Pleasanton
Your furnace’s blower motor runs year-round whenever the air handler moves air, including during AC season. In Pleasanton tract homes built from 1987 to 2005, the original builder-grade return ducts are often too small for the airflow the system needs, which overheats the blower motor and causes it to trip on thermal overload. The fix is a combination of sealing and balancing the ducts, verifying static pressure, and replacing the failed motor. Call (747) 966-3037 and we’ll test your static pressure before we ever sell you a part.
Yes, if the repair involves a heat exchanger replacement, blower motor replacement, or any change that affects airflow, a load calculation is the honest way to size the work. Many original Pleasanton furnaces were sized by rule of thumb rather than an actual Manual J calculation, which is part of why so many systems in the valley run against restricted airflow. Our team includes the load numbers in the written quote, and it doesn’t cost you extra to have it done right.
The Title 24 duct leakage test is a California requirement on any new furnace or AC replacement install, and it measures how much conditioned air your ductwork leaks. Homes in Pleasanton built between 1987 and 2005 commonly have duct systems that leak 20-30% or more, so failing the test adds sealing work and permit costs to a replacement job. We flag this before the work starts so there are no surprises on the final invoice.
If your heat exchanger is cracked, we shut the furnace down immediately because it can release carbon monoxide into your home. On a furnace under 15 years old with a clean service history, a heat exchanger replacement under warranty may make sense, costing $400-$700 for the labor. On a 25-35-year-old builder-grade furnace in a Pleasanton tract home, replacement is usually the better call. We’ll show you the written numbers for both and let you decide without pressure.
Pleasanton’s Amador Valley climate drops 30-40°F from afternoon to early morning in spring and fall, which makes single-stage thermostats and older two-stage logic cycle strangely. Short-cycling, blower run-on, or a furnace that fires at odd hours is often a thermostat calibration or staging issue, not a gas valve failure. We check the thermostat’s placement, calibration, and staging logic before we recommend any part replacement.
When your furnace quits in Pleasanton, call (747) 966-3037. Luis Serrano and the Meadowsweet Heating & Air team will answer live, schedule a same-day visit, and give you a written price before any work starts. We’ll leave your home as clean as we found it, with a photo to prove it, and we’ll stand behind the repair for 365 days.
