Furnace repair in Livermore typically costs $150–$700, replacement runs $3,500–$7,500, and we’re usually on-site the same day you call. Meridian Heating & Air Los Angeles has handled heating and furnace work in Livermore for nearly two decades, from cracked heat exchangers in 1970s ranch homes near East Avenue to full system swaps in the newer subdivisions off North Livermore. We’re familiar with the valley’s punishing summer heat, the Altamont winds that hammer outdoor units, and the older housing stock that wasn’t built for modern cooling loads. If your furnace is blowing cold air, cycling on and off, or you suspect a carbon monoxide issue, call us at (877) 454-5066. Estimates are free.
Why Meridian Heating & Air Los Angeles Is Livermore’s Preferred Heating & Furnace Company
We’ve built our reputation in Livermore one service call at a time. Our Heating & Furnace crew knows the difference between a 1968 ranch near Murrieta Boulevard with original ductwork and a 2005 build in north Livermore with a builder-grade system hitting its twentieth winter. That local knowledge saves time and money.
286 customers have left reviews averaging 4.8 stars. Many are from right here in Livermore, and they mention the same thing: Anthony Moreno, our founder and lead installer, shows up on the job himself. Not a rotating subcontractor. Not a dispatcher sending whoever’s available. The same hands that have been installing and repairing furnaces for 19 years.
We stock parts for Rheem, York, Daikin, Bryant, and the other major brands we service. That means faster turnaround for Livermore customers. No waiting a week for a gas valve or ignitor to ship from a warehouse three states away.
Our emergency HVAC service is available for urgent situations. When a heat exchanger cracks during a cold snap or a gas valve fails on a Friday night, Livermore homeowners aren’t left waiting until Monday morning.
Our Heating & Furnace Services in Livermore
Furnace Repair
Furnace repair in Livermore runs $150–$700 depending on the part and accessibility. We see a lot of gas valve corrosion in older units here, especially ones with exterior flues exposed to salt air blown through the Altamont Pass. Ignitor failures are common too, often from the thermal stress of repeated cycling during Livermore’s big temperature swings. We carry replacement ignitors, gas valves, blower motors, and control boards for most major brands, so most repairs finish in a single visit.
Furnace Replacement
A full furnace replacement in Livermore typically costs $3,500–$7,500 installed, including basic duct modifications. This is our most called-for service in the 94550 and 94551 ZIP codes. Many Livermore homes still run original 1970s–80s furnaces that were never designed to work with modern air conditioning retrofits. We size the new unit properly for both heating and cooling loads, seal leaky attic duct runs, and make sure the blower can handle the static pressure of your existing or planned duct system. Anthony Moreno personally leads every installation.
Furnace Tune-Up
Our furnace tune-up in Livermore costs $80–$200 and takes about 90 minutes. We check heat exchanger integrity with a visual inspection and combustion analysis, test gas pressure and valve operation, clean burners, and measure temperature rise across the coil. In Livermore’s climate, with hot days and cool nights forcing equipment to cycle heavily, annual tune-ups catch cracks and corrosion before they become safety hazards. We recommend fall service, before the first cold snap sends everyone calling at once.
Heat Exchanger Inspection & Replacement
Heat exchanger cracks are a serious safety issue we find regularly in Livermore’s older housing stock. The valley’s large diurnal temperature swings, hot days followed by 50°F nights, cause repeated expansion and contraction stress that fatigues metal over decades of service. A cracked exchanger can leak carbon monoxide into your living space. We inspect every furnace we touch, and if we find a crack, we’ll show you with a camera. Replacement heat exchangers run $800–$2,200 depending on the unit; sometimes full replacement makes more sense.

Trusted Brands We Service in Livermore
We work on your brand, not just the ones we prefer to sell. Our technicians are factory-trained or experienced on nine major HVAC manufacturers: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Rheem, York, Daikin, and Bryant locally, which means Livermore customers with those systems often get same-day repairs. For less common components, our supplier relationships get us next-day delivery to the Livermore Valley. Whether you need a gas valve for a 1990s Bryant or a control board for a newer Daikin modulating furnace, we’ve handled it before.
Common Heating & Furnace Problems We See in Livermore Homes
- Heat exchanger cracks from thermal cycling. Livermore’s 40°F+ temperature swings between day and night force furnaces to cycle repeatedly through expansion and contraction. In 1960s–80s units with thin-walled steel exchangers, that stress accumulates into cracks that can leak carbon monoxide. We catch these during tune-ups before they become emergencies.
- Undersized blowers failing in original duct systems. Many Livermore ranch homes near East Avenue and the Murrieta corridor have original ductwork sized only for heating airflow. When homeowners add central AC or even run the fan continuously for air circulation, the blower motor overheats and burns out prematurely. We measure static pressure and airflow before recommending any repair.
- Gas valve corrosion from Altamont Pass winds. Salt-laden air funnels through the Altamont and settles on exterior flues and vent terminations. Older furnaces with unprotected components show corroded gas valves and flame sensors that fail intermittently, often on the coldest nights when the furnace works hardest.
- Short cycling in 1970s two-story tract homes. Poor zoning and undersized returns cause these systems to heat the first floor quickly while the second floor stays cold, triggering the limit switch and shutting the furnace down before a full cycle completes. The constant starting and stopping wears out motors, ignitors, and control boards years early.

What moves the needle within these ranges? Accessibility matters. A furnace in a tight attic crawl space near downtown Livermore takes longer to service than a garage installation in a newer north Livermore home. Parts availability for your specific brand and model affects timing. And the condition of your ductwork, if we need to modify or seal runs to make the new furnace work properly, can add labor. We price every job upfront after inspection, not after we’ve started work. Call (877) 454-5066 for a free estimate.

FAQs — Heating & Furnace in Livermore
Livermore’s extreme diurnal temperature swings, hot days followed by cool nights, force furnaces to cycle through repeated heating and cooling cycles that stress metal heat exchangers over time. The 1960s–80s furnaces common in Livermore’s older neighborhoods were built with thinner steel and shorter expected lifespans than modern units. After 30–40 years of thermal cycling, cracks develop at stress points, especially in units that have been oversized or short-cycling. We inspect every heat exchanger we access and will show you camera footage if we find a problem. Call (877) 454-5066 to schedule a safety check.
Not always, but often it’s the smartest path. Many Livermore homes were built with furnaces sized only for heating, with blowers and ductwork that can’t handle the airflow demands of central cooling. We’ve seen too many AC retrofits where a new condenser gets paired with an old furnace, and the system never performs properly. During our free estimate, we measure your existing duct capacity, blower CFM, and static pressure to tell you honestly whether your furnace can support AC or if replacement makes sense. Call (877) 454-5066 and we’ll assess your specific setup.
Strong afternoon winds from the Altamont Pass, routinely 15–30 mph, carry salt and particulates that corrode exterior furnace components, especially gas valves, flame sensors, and vent terminations on older units. We’ve replaced more gas valves in Livermore’s exposed hillside homes than in sheltered inland locations. If your furnace sits on a windward wall or your flue termination faces east toward the Pass, that exposure accelerates wear. We can recommend shielding options or upgraded components with better corrosion resistance. Call (877) 454-5066 if you’ve had repeated ignition or valve failures.
Short cycling in 1970s Livermore homes usually stems from ductwork that was never designed for the airflow your furnace needs to run a full cycle. Original systems often have undersized returns, single-zone controls for two-story layouts, or ducts run through unconditioned attics that lose heat before it reaches living spaces. The furnace overheats, hits the high-limit switch, and shuts down prematurely. That constant starting and stopping wears out motors and ignitors. We measure airflow and static pressure to find the root cause, reinsulate ducts, add returns, or resize equipment as needed. Call (877) 454-5066 for diagnostics.
If your ducts run through an uninsulated Livermore attic, reinsulating before furnace replacement often delivers more comfort improvement than upsizing the unit itself. We’ve found original duct runs in East Avenue and Murrieta corridor homes with zero insulation wrap, baking supply air in summer and bleeding heat in winter. A new high-efficiency furnace can’t overcome that loss. We typically recommend sealing with mastic and wrapping with R-8 insulation minimum, which runs $800–$2,400 depending on linear footage. We bundle this with furnace replacement when it makes sense. Call (877) 454-5066 for an attic duct assessment with your free estimate.
