When your furnace quits on a cold Fairfield night, you don’t have time for vague appointment windows or technicians who show up unprepared. You need someone who picks up the phone, shows up when they say they will, and carries the parts to actually fix your system.
That’s what happens when you call Hot & Cold HVAC. Our trucks are stocked with common repair parts for all major brands. Most furnace repairs get completed the same day you call, because we understand that waiting around in a cold house isn’t an option when you’ve got kids, pets, or elderly family members counting on you.
You get transparent pricing before any work starts. No surprise charges after the fact. No upselling you on stuff you don’t need. Just a clear diagnosis, an honest quote, and a heating system that works again.
We serve Sacramento and Placer counties because we got tired of watching neighbors get hit with surprise charges and sloppy work. Every technician on our team holds proper California C-20 HVAC licensing and carries full liability insurance, so you’re protected if anything goes wrong.
We’ve been fixing furnaces through Fairfield’s cold snaps and Delta breeze shifts long enough to know exactly what breaks and why. Your system faces unique challenges here—coastal humidity mixing with temperature swings that stress components differently than inland areas. We don’t just patch problems. We diagnose what’s actually failing and explain it in plain terms.
You can text us at 916-519-1248 if that’s easier than calling. We answer either way, and we show up ready to work.
You call or text us with your heating problem. We ask a few quick questions to understand what’s happening—no heat at all, strange noises, uneven heating, high bills, whatever you’re dealing with. If it’s an emergency, we prioritize you and typically arrive within 2-4 hours.
When our technician shows up, they run a full diagnostic on your system. That means checking your thermostat settings, inspecting your furnace’s ignition system, testing airflow, examining ductwork connections, and looking for safety issues like gas leaks or carbon monoxide concerns. We use actual diagnostic equipment, not guesswork.
Once we know what’s wrong, we explain it to you in normal language and give you an upfront price. If you approve, we fix it right then if we’ve got the parts on the truck—which we usually do. If it’s something unusual, we’ll get the part and come back fast. After the repair, we test the system to make sure it’s heating properly and efficiently. Then we clean up and get out of your way.

Every furnace repair call includes a complete system diagnostic, not just a quick look at the obvious problem. We check your thermostat calibration, inspect your heat exchanger for cracks, test your blower motor, examine your flame sensor, and look at your ductwork for leaks that waste energy.
Fairfield’s proximity to the Delta means your system deals with more humidity than furnaces in drier parts of Sacramento County. That moisture accelerates corrosion on electrical components and control boards. We specifically check those vulnerable points because we’ve seen them fail more often in this area.
You also get a filter inspection and airflow assessment. Blocked filters and restricted airflow cause most of the service calls we run in Fairfield—they make your furnace work harder, drive up your energy bills, and eventually burn out your blower motor. If your filter’s clogged, we’ll tell you. If your ductwork’s leaking conditioned air into your attic or crawlspace, we’ll show you where and explain what it’s costing you.
We service all major brands—Trane, Carrier, Lennox, Rheem, Goodman, York, and others. If it heats your home, we can fix it.
Most furnace repairs in Fairfield run between $200 and $600 depending on what’s broken and which parts need replacing. Simple fixes like a bad thermostat or dirty flame sensor cost less. Bigger repairs like a failed blower motor or cracked heat exchanger cost more.
We charge a diagnostic fee of around $90-$100 to come out, figure out what’s wrong, and give you an exact quote. If you approve the repair, that diagnostic fee usually gets applied to your total cost. We don’t believe in surprise charges or vague estimates that balloon after the work’s done.
The honest truth is that some repairs don’t make financial sense if your furnace is old and inefficient. If we’re looking at an $800 repair on a 20-year-old system that’s going to fail again soon, we’ll tell you. Sometimes replacement is the smarter move, and we’ll explain why without pressuring you either way.
Yes. Most of our furnace repair calls in Fairfield get completed the same day you contact us, as long as you call during business hours. We keep our service trucks stocked with common parts for all major furnace brands, so we’re not making multiple trips or ordering parts that take days to arrive.
If you’ve got an emergency—no heat at all during cold weather, families with young kids or elderly residents, potential safety issues like gas smells—we prioritize your call and typically arrive within 2-4 hours. We run 24/7 emergency service during winter months because we know furnace failures don’t wait for convenient times.
The only time we can’t complete a repair same-day is when your system needs an unusual part we don’t stock. Even then, we’ll get it ordered on priority and come back as fast as possible. We’re not interested in dragging out your discomfort or racking up multiple service call fees.
Dirty or clogged air filters cause more furnace problems in Fairfield than anything else. When airflow gets restricted, your system overheats, cycles on and off constantly, and eventually fails. It’s the easiest problem to prevent but the most common one we see.
Thermostat issues rank second—bad calibration, dead batteries, wiring problems, or thermostats installed in the wrong location where they’re reading temperatures that don’t match the rest of your house. Fairfield’s temperature swings between day and night confuse poorly calibrated thermostats and cause short-cycling.
Ignition and flame sensor problems come up frequently, especially on furnaces that sat unused through summer and fall. When you fire up your heat for the first time in October, that’s when you discover your igniter’s cracked or your flame sensor’s covered in carbon buildup. We also see more corrosion on electrical components here than in drier areas because of Delta humidity. Control boards, relays, and capacitors fail faster when moisture gets into your system.
If your furnace is under 15 years old and the repair costs less than half the price of a new system, repair usually makes sense. If you’re looking at expensive repairs on a furnace that’s 18-20 years old, replacement is probably smarter because you’re just delaying the inevitable.
Watch for signs that your furnace is struggling—rooms that never get warm, constantly rising energy bills, frequent breakdowns that keep requiring service calls, strange noises like banging or screeching, or yellow flames instead of blue on gas furnaces. Those symptoms mean your system is wearing out.
We’ll be straight with you about whether repair or replacement makes more financial sense. Sometimes a $400 repair buys you another 5-7 years of reliable heating. Other times you’re throwing money at a system that’s going to fail again in six months. We’ve got no incentive to push you toward the more expensive option—we make money either way, and we’d rather you trust us for the long term than feel like we oversold you once.
Yes, we provide 24/7 emergency heating repair throughout Fairfield and Sacramento County. When you’ve got no heat during cold weather, we prioritize your call and typically arrive within 2-4 hours, even on nights and weekends.
We consider it an emergency if you’ve got no heat at all, if you smell gas near your furnace, if you’re hearing loud banging or grinding noises, or if you’ve got young children or elderly family members in a cold house. Those situations get immediate response because they’re either safety issues or genuine comfort emergencies.
Emergency service does cost more than regular business hours—that’s standard across the HVAC industry because we’re pulling technicians away from their families at odd hours. But we’re upfront about that pricing before we dispatch anyone. You’ll know exactly what you’re paying before we head your way. And you still get the same thorough diagnostic and quality repair you’d get during normal hours.
We repair all major furnace brands including Trane, Carrier, Lennox, Rheem, Goodman, York, Amana, Bryant, American Standard, and others. Our technicians are trained on the most common residential and light commercial systems installed throughout Fairfield and Sacramento County.
Different brands have different common failure points. Goodman furnaces tend to have control board issues. Carrier systems sometimes develop inducer motor problems. Rheem units can have ignition system quirks. We’ve worked on enough of each brand to know their weak spots and keep the right parts stocked.
If you’ve got an unusual or very old brand, we’ll still come diagnose it. Worst case, we might need to order a specific part, but we can usually figure out what’s wrong and get you a solution. The basic components—blower motors, gas valves, flame sensors, thermocouples—work similarly across brands even if the specific part numbers differ.
