You’re not looking for a relationship. You need your furnace working before tonight when temperatures drop into the 40s.
That’s what same-day service means here. A licensed technician shows up, diagnoses the problem, gives you the exact cost before any work starts, and gets your heat back on. No hidden fees tacked on at the end. No pressure to replace your entire system if a repair will do the job.
Most furnace repairs in Vacaville happen because of clogged filters, faulty igniters, or thermostat issues. These aren’t complicated fixes, but they do require someone who knows what they’re doing and has the parts on hand. Our trucks carry the most common components for all major furnace brands, which means fewer trips back to the shop and faster turnaround for you.
Hot & Cold HVAC serves Sacramento and Placer counties, including Vacaville and the surrounding areas. Every technician on our team holds an HVAC Pro License and liability insurance coverage. That’s not optional—it’s how we operate.
We know what Vacaville winters look like. Mild compared to other parts of the country, sure, but when your furnace quits on a damp 38-degree morning, mild doesn’t cut it. You need heat, and you need someone who can fix it without dragging out the process or inflating the bill.
We’ve built our reputation on showing up when we say we will, being clear about what’s wrong and what it costs, and doing the work right the first time. That’s it.
You call or text (916) 519-1248. We schedule a same-day appointment if you need it, or we book a time that works for your schedule.
A licensed technician arrives and runs a full diagnostic on your furnace. That includes checking the igniter, blower motor, heat exchanger, thermostat, filters, and gas connections. Once we know what’s wrong, we explain it in plain terms—not HVAC jargon—and give you an upfront price for the repair.
If you approve the work, we handle it on the spot in most cases. If we need to order a part, we’ll let you know how long it’ll take and whether there’s a temporary fix to keep you warm in the meantime. After the repair, we test the system to make sure it’s running properly and walk you through what we did.
You’ll get an itemized invoice with no surprise charges. Everything we quoted is everything you pay.

Every furnace repair starts with a full system diagnostic. We’re not guessing. We’re checking every component that could cause your furnace to fail, including the igniter, flame sensor, blower motor, limit switch, thermostat calibration, and gas valve operation.
If your furnace is older or hasn’t been maintained regularly, we’ll also inspect the heat exchanger for cracks. A cracked heat exchanger is a safety issue—it can leak carbon monoxide into your home. If we find one, we’ll explain your options clearly. Sometimes a repair makes sense. Sometimes it doesn’t. We’ll give you the information you need to decide.
Vacaville’s climate is easier on HVAC systems than Sacramento’s triple-digit summers, but your furnace still works hard during winter months. Dust, debris, and normal wear add up over time. A tuned-up furnace runs more efficiently, which can cut your energy bills by up to 40% compared to a neglected system. That’s not marketing talk—that’s what happens when airflow improves and your system doesn’t have to work overtime to heat your home.
We service all major furnace brands. Whether you have a Carrier, Trane, Lennox, Rheem, Goodman, or another brand, our technicians have the training and parts to handle it.
Most furnace repairs in Vacaville run between $150 and $500, depending on what’s broken. A simple fix like replacing a clogged filter or resetting a tripped breaker costs less. Replacing an igniter, flame sensor, or blower motor costs more.
You’ll know the exact price before we start any work. We don’t give estimates that balloon into something else once the job’s done. The quote we give you is the price you pay, parts and labor included.
If your furnace needs a major component like a heat exchanger or if the system is old enough that repairs don’t make financial sense, we’ll tell you that too. We’re not here to sell you a new furnace if a $200 repair gets you through another few winters. But we’re also not going to patch up a failing system and leave you with another breakdown in two months.
Yes. We offer 24/7 emergency service for furnace breakdowns, including nights, weekends, and holidays. If your heat goes out and it’s a safety concern—especially if you have young kids, elderly family members, or health conditions that make cold temperatures dangerous—call us.
Emergency service costs more than a standard appointment because we’re pulling a technician off-call or after-hours. We’ll tell you the emergency rate upfront when you call so there’s no confusion.
Not every furnace issue is an emergency. If your system is running but not heating efficiently, or if you’re hearing strange noises but still have some heat, you can usually wait for a regular appointment. If you have no heat at all and it’s cold outside, that’s when emergency service makes sense. We’ll help you figure out which situation you’re in when you call.
Most furnace repairs take one to three hours, start to finish. That includes diagnosing the problem, getting your approval, completing the repair, and testing the system to make sure it’s working.
Simple fixes like replacing a thermostat, cleaning a flame sensor, or swapping out an igniter usually take an hour or less. More involved repairs—like replacing a blower motor or control board—can take two to three hours depending on your furnace model and how accessible the components are.
If we need to order a part that’s not on the truck, the timeline changes. We’ll let you know how long the part will take to arrive and whether we can rig a temporary solution to keep you warm while we wait. In most cases, we stock the common parts for major brands, so same-day completion is typical.
Clogged air filters are the number one issue we see. When airflow gets restricted, your furnace works harder, overheats, and eventually shuts down. Changing your filter every one to three months can prevent most of these calls.
Faulty igniters are another common problem, especially in furnaces that are 10+ years old. The igniter is what lights the gas to create heat. When it fails, your furnace won’t produce any warm air. Replacing an igniter is straightforward and gets your system back online quickly.
Thermostat issues cause a lot of service calls too. Sometimes it’s as simple as dead batteries or incorrect settings. Other times the thermostat itself has failed and needs replacement. We’ll test the thermostat during every diagnostic to rule it out or confirm it’s the problem. Vacaville’s mild but damp winters can also lead to issues with limit switches and flame sensors, especially if your furnace hasn’t been maintained regularly.
If your furnace is less than 15 years old and the repair costs less than half the price of a new system, repairing usually makes sense. If your furnace is older than 15 years or the repair costs more than 50% of a replacement, you’re better off replacing it.
There are exceptions. If you’re planning to sell your home in the next year or two, a repair might get you through until closing. If your furnace has already needed multiple repairs in the past few years, you’re likely looking at more breakdowns ahead, and replacement becomes the smarter financial move.
We’ll give you both options when it makes sense to do so. We’re not a company that pushes new equipment when a repair will do the job. But we’re also not going to tell you to keep dumping money into a furnace that’s on its last legs. You’ll get honest information about the condition of your system, the expected lifespan of the repair, and what a replacement would cost. Then you decide.
Yes. We service all major furnace brands, including Carrier, Trane, Lennox, Rheem, Goodman, York, Amana, American Standard, Bryant, and others. Our technicians are trained on the most common residential systems in Vacaville and Sacramento County, and our trucks carry parts for the brands we see most often.
If you have a less common brand or a very old model, we’ll still come out and diagnose the issue. In some cases, parts might take longer to source, but we’ll let you know that upfront and work with you on timing.
Brand doesn’t usually matter as much as maintenance history. A well-maintained Goodman will outlast a neglected Carrier. What matters is whether your furnace has been serviced regularly, whether the filters have been changed, and whether small issues were caught before they became big ones. We’ll assess the overall condition of your system during the repair and let you know if there are other concerns worth addressing.
