You’re not looking for a sales pitch. You need your furnace working before tonight gets cold.
Most San Ramon homes were built around 1993, which means a lot of furnaces are hitting that 20-year mark where things start breaking. Igniters fail. Blower motors wear out. Thermostats stop communicating. These aren’t always replacement-level problems, but they do need someone who knows what they’re doing.
We show up with the parts, the license, and the experience to diagnose what’s actually wrong. You get a straight answer about whether it’s worth repairing or if you’re better off replacing. No upselling. No scare tactics. Just honest guidance based on what we see.
Same-day service means you’re not waiting three days for someone to show up. Upfront pricing means you know the cost before we start. And if it’s an emergency, we’re available 24/7 during extreme weather because we know furnaces don’t fail on your schedule.
Hot & Cold HVAC serves both Sacramento and Placer counties with fully licensed technicians and liability insurance that protects your home. We’re not a call center routing you to the lowest bidder. We’re a local heating contractor you can text at 916-519-1248 if you have a question.
San Ramon homeowners deal with unique climate swings and high energy costs. We train our techs specifically for Sacramento County conditions so they understand how your system should perform here, not just in general. That matters when diagnosing efficiency issues or recommending repairs that actually make sense for your home.
We’ve built our reputation on being reachable, transparent, and good at what we do. You’ll get the same tech who answers your questions, not a different crew every visit.
You call or text us at 916-519-1248. We ask a few questions about what’s happening with your furnace so we can bring the right parts and tools.
We schedule same-day service if you need it, or pick a time that works for your schedule. When we arrive, we diagnose the issue, explain what’s wrong in plain language, and give you an upfront price before we touch anything.
If it’s a simple fix, we handle it on the spot. If it’s more involved, we walk you through your options, including whether a repair makes financial sense or if you’re throwing money at a system that’s done. You decide. We don’t pressure.
Once the work’s approved, we complete the repair, test the system to make sure it’s heating properly, and clean up. You get a receipt, a warranty on the work, and a working furnace. If something doesn’t seem right after we leave, you call us back. We stand behind what we do.
Ready to get started?
Every furnace repair starts with a full diagnostic. We check the thermostat, inspect the igniter or pilot light, test the blower motor, examine the heat exchanger for cracks, and measure airflow. We’re looking for the root cause, not just the symptom.
Common repairs include replacing faulty igniters, fixing blower motors, recalibrating thermostats, cleaning flame sensors, and addressing airflow restrictions. We also check your filter, because a clogged filter causes half the service calls we see. If your ductwork is leaking or your system is undersized for your home, we’ll tell you that too.
San Ramon’s energy costs make efficiency matter. If your furnace is running but your bills are climbing, we can tune it up to improve performance. A properly maintained furnace can save you up to 40% on heating costs, which adds up fast when you’re paying California energy rates.
We service all major brands: Carrier, Trane, Lennox, Rheem, Goodman, York, Amana, and more. If it heats your home, we’ve worked on it. And if you need boiler repair instead of forced-air furnace work, we handle that too.
Most furnace repairs in San Ramon run between $150 and $500, depending on what’s broken. A simple fix like replacing a flame sensor or thermostat usually costs $150 to $250. Blower motor replacements or igniter issues typically fall in the $250 to $450 range. More complex repairs involving the heat exchanger or gas valve can push toward $500 or more.
We give you the price upfront before we start any work. No surprise charges, no hidden fees. If the repair cost is approaching 50% of a new furnace and your system is over 15 years old, we’ll have an honest conversation about whether fixing it makes sense or if you’re better off replacing.
San Ramon homeowners should also factor in energy savings. An inefficient furnace costs you every month it runs. Sometimes a repair that improves efficiency pays for itself in lower utility bills within a year or two.
If your furnace is under 15 years old and the repair costs less than half of a new system, fixing it usually makes sense. If it’s over 20 years old, needs frequent repairs, or the heat exchanger is cracked, replacement is often the smarter move.
Here’s what we look at: age of the system, frequency of breakdowns, efficiency rating, and whether parts are still available. A furnace that’s needed three repairs in two years is telling you something. So is one that runs constantly but never gets your home warm.
Cracked heat exchangers are non-negotiable. That’s a safety issue because it can leak carbon monoxide into your home. We don’t patch those. We recommend replacement immediately. But if your furnace just needs a new blower motor and it’s only 10 years old, that’s a straightforward repair that buys you several more years of reliable heat.
We’ll walk you through the math and let you decide. Some homeowners want to squeeze another few years out of an older system. Others want the peace of mind and efficiency of a new one. Both are valid choices depending on your situation.
Yes. If you call us in the morning, we can usually get to you the same day. We keep common parts stocked on our trucks so we’re not making multiple trips or ordering parts that take three days to arrive.
Same-day service matters most during cold snaps when your furnace fails and you’ve got kids or elderly family members in the house. We prioritize emergency calls during extreme weather and offer 24/7 availability when temperatures drop.
San Ramon doesn’t get Minnesota winters, but when it’s 35 degrees at night and your heat goes out, it’s still miserable. We’ve seen enough December and January breakdowns to know that waiting until tomorrow isn’t always an option. If you need us tonight, text or call 916-519-1248 and we’ll get someone out.
We repair all major furnace brands: Carrier, Trane, Lennox, Rheem, Goodman, York, Amana, Bryant, Ruud, Coleman, Heil, and more. Our techs are trained on both older and newer models, so we’re not turning away jobs because we “don’t work on that brand.”
A lot of San Ramon homes have builder-grade systems installed in the 90s when the neighborhoods were developed. Those are often Carrier, Lennox, or Rheem units. We’ve worked on hundreds of them and know their common failure points.
If you’ve got a newer high-efficiency furnace or a heat pump system, we handle those too. We stay current on training because the technology keeps evolving. Variable-speed blowers, modulating gas valves, smart thermostats—we’ve installed and repaired all of it.
The only time we can’t help is if your furnace is so old that parts are discontinued and unavailable. In that case, we’ll tell you upfront and help you understand your replacement options.
Once a year, ideally in early fall before you start using your heat regularly. Annual maintenance catches small problems before they become expensive repairs and keeps your furnace running efficiently.
A furnace tune-up includes cleaning the burners, checking the igniter, testing the blower motor, inspecting the heat exchanger, calibrating the thermostat, and replacing the filter. We also measure airflow and combustion efficiency to make sure your system is heating your home without wasting energy.
Skipping maintenance is like never changing your car’s oil. It’ll run fine for a while, then something fails at the worst possible time. San Ramon homeowners who schedule annual tune-ups have fewer emergency breakdowns and lower energy bills. The service typically pays for itself in energy savings within the first season.
If you’ve got an older furnace, maintenance becomes even more important. Those systems need more attention to stay reliable. If you’ve got a newer high-efficiency model, maintenance protects your warranty and keeps it performing the way it’s supposed to.
Yes. We serve both Sacramento and Placer counties, which includes San Ramon, Sacramento, Roseville, Elk Grove, Folsom, Citrus Heights, Rocklin, and surrounding areas. Our service area is broad because we’ve built the team and capacity to cover it reliably.
If you’re in Carmichael, Rancho Cordova, Fair Oaks, Orangevale, or any of the other nearby communities, we can get to you the same day in most cases. We’re not a small operation that only covers a five-mile radius, but we’re also not a national franchise that doesn’t know the local market.
Sacramento County and Placer County have different climate patterns, building codes, and energy costs. We train our techs to understand those differences so the advice you get is relevant to where you live. A furnace repair recommendation in Roseville might look different than one in Galt because the homes, systems, and usage patterns vary.
If you’re outside our service area, we’ll tell you upfront instead of wasting your time. But if you’re anywhere in the greater Sacramento region, we’ve probably worked in your neighborhood before.
