When your AC quits on a 105-degree afternoon or your furnace stops working during a cold snap, you don’t have time for runaround. You need someone who shows up fast, diagnoses the problem correctly, and fixes it without surprise charges on the back end.
That’s what you get with a licensed HVAC contractor who knows Newcastle. Your system runs efficiently, your indoor air stays clean during fire season, and your energy bills drop—sometimes by as much as 40% when your equipment is properly optimized for our climate.
You’re not just getting a repair. You’re getting a system that handles the temperature swings between day and night, filters out pollen and smoke, and doesn’t break your budget every time the mercury climbs. That’s the difference between a quick fix and a real solution.
We serve both Sacramento and Placer counties with fully licensed, insured technicians who live and work in this area. We started Hot & Cold HVAC because too many homeowners were getting hit with surprise charges, poor workmanship, and contractors who didn’t understand what Newcastle systems face.
You’ll know the exact cost before we start any work. No hidden fees, no upselling you don’t need, no games. Just honest service from people who understand that when your HVAC goes down in extreme weather, it’s not just uncomfortable—it’s urgent.
We’re available 24/7 for emergencies, and we offer same-day service when you need it most. You can even text us at (916) 519-1248 if that’s easier than a phone call.
First, we listen. You tell us what’s going on—whether your system isn’t cooling, you’re hearing strange noises, or your energy bills just doubled. We ask a few questions to understand the situation before we even roll out.
Then we schedule a time that works for you, often same-day if it’s an emergency. Our technician shows up on time, diagnoses the issue, and explains what’s wrong in plain language. No jargon, no scare tactics.
Before any work starts, you get upfront pricing. You’ll know exactly what it costs and why. If you approve, we fix it right then and there whenever possible. After the repair, we test the system to make sure everything’s running correctly and answer any questions you have.
You get a guarantee on the work, and if something doesn’t feel right later, you call us back. That’s how it should work.
Ready to get started?
You get a licensed technician who’s trained specifically for Newcastle’s climate—the extreme summer heat that makes your AC work overtime, the wildfire smoke that clogs filters and corrodes components, and the temperature swings that stress your system daily.
We service all major HVAC brands, so whether you have a Carrier, Trane, Lennox, or something else, we can repair it. We handle everything from emergency breakdowns to routine maintenance, heat pump installations to whole-home air filtration systems that protect you during fire season.
Energy efficiency is part of every job we do. We’re not just fixing what’s broken—we’re making sure your system runs as efficiently as possible so you’re not throwing money away every month. With proper optimization, most Newcastle homeowners save up to 40% on their energy costs.
You also get compliance with California’s 2024 energy standards. If your system needs replacement, we install equipment that meets the new SEER2 and HSPF2 requirements, which means better efficiency and lower bills long-term, even if the upfront cost is slightly higher.
We offer same-day service for emergencies, and we’re available 24/7 when extreme weather hits. If your AC goes out during a heat wave or your furnace quits on a cold night, we prioritize those calls because we know you can’t wait.
Response time depends on where our techs are when you call, but most emergency calls in Newcastle get a technician within a few hours. We serve both Sacramento and Placer counties, so we’re never far from your area.
When you call, we’ll give you an honest timeframe and keep you updated if anything changes. You can also text us at (916) 519-1248 if that’s easier—we know not everyone wants to sit on hold during an emergency.
It depends on what’s wrong with your system. A simple repair like replacing a capacitor might run a few hundred dollars, while a full system replacement can range from several thousand to over ten thousand depending on the size of your home and the equipment you choose.
Here’s what matters more than a ballpark number: you’ll know the exact cost before we start any work. We give you upfront pricing after diagnosing the problem, and that price doesn’t change unless you approve additional work.
We don’t do the thing where the final bill is mysteriously higher than the estimate. You’ll see the cost breakdown, understand what you’re paying for, and decide whether to move forward. No surprises, no pressure.
You need a licensed contractor, especially in California. Licensing means the technician has passed state exams, carries proper insurance, and is legally allowed to work on your system. If something goes wrong with an unlicensed contractor—like improper installation or damage to your home—you have zero recourse.
California’s 2024 energy standards also require compliance with new SEER2 and HSPF2 ratings. If an unlicensed contractor installs a non-compliant system, you risk voided warranties, failed inspections, and denied permits. That “cheaper” option ends up costing you way more when you have to redo the work correctly.
Licensed contractors also understand local code requirements and pull the necessary permits. That protects you if you ever sell your home, because unpermitted HVAC work can kill a sale or force you to replace the entire system before closing.
Age is the first clue. If your system is over 15 years old and needs a major repair—like a compressor or heat exchanger—replacement usually makes more sense financially. You’re putting money into equipment that’s near the end of its lifespan anyway.
Frequency of repairs matters too. If you’re calling for service multiple times a year, those costs add up fast. At a certain point, you’re better off investing in a new system that runs efficiently and doesn’t break down constantly.
Energy bills are another indicator. If your costs have climbed significantly even though your usage hasn’t changed, your system is probably struggling. Older equipment loses efficiency over time, and with Newcastle’s extreme heat, an inefficient AC can cost you hundreds extra every summer. We’ll assess your specific situation and give you an honest recommendation—repair or replace—based on what actually makes sense for your home and budget.
Yes. Wildfire smoke is a serious issue in the Sierra Nevada foothills, and your HVAC system is your first line of defense for indoor air quality. We install whole-home air filtration systems that capture smoke particles, pollen, and other contaminants before they circulate through your house.
Standard HVAC filters aren’t designed to handle wildfire smoke. You need HEPA-grade filtration or an electronic air cleaner that can trap the fine particulate matter that makes smoke so dangerous. We’ll assess your current system and recommend the right filtration setup for your home size and ductwork.
We also check for leaks in your ductwork, because even the best filter won’t help if smoke is getting pulled in through gaps and cracks. Sealing your ducts and upgrading your filtration gives you clean air even when the AQI outside is in the red. It’s especially important if anyone in your home has asthma, allergies, or other respiratory issues.
We handle residential HVAC and light commercial work. That includes single-family homes, townhouses, small office buildings, retail spaces, and similar properties. If you’re a homeowner dealing with a broken AC or a small business owner whose heating system isn’t keeping up, we can help.
For larger commercial projects—like industrial facilities or multi-story commercial buildings—we’d refer you to a contractor who specializes in that scale of work. We focus on residential and light commercial because that’s where we have the most experience and can deliver the best results.
Our service area covers both Sacramento and Placer counties, so whether you’re in Newcastle proper, Granite Bay, Auburn, or any of the surrounding communities, we’ve got you covered. Same licensing, same transparent pricing, same commitment to getting your system running right.
