Your furnace kicks on when it’s -18°F outside. Your AC handles 90-degree summer days without breaking down mid-afternoon. Your utility bills drop because the system isn’t fighting itself to maintain temperature.
That’s what happens when an HVAC contractor near me understands South Lake Tahoe’s altitude and weather extremes. Most systems up here work harder than they should because they weren’t installed or maintained by someone who knows what 6,200 feet does to equipment performance.
You’re not dealing with Sacramento valley conditions. You’re managing freeze-thaw cycles, massive temperature swings between day and night, and snow loads that affect outdoor units from November through April. Your system needs to handle all of that without you thinking about it.
When your HVAC works the way it should, you’re not checking the thermostat every hour. You’re not calling for emergency repairs during a cold snap. You’re not opening bills wondering why your heating costs doubled last month.
Hot & Cold HVAC serves South Lake Tahoe, CA and the greater Sacramento and Placer County areas. We’re based in Citrus Heights, CA, and every technician on our team holds an HVAC Pro License with full liability insurance coverage.
We built this company because too many homeowners in the Tahoe basin were getting hit with surprise charges, poor workmanship, and technicians who didn’t understand what altitude does to HVAC performance. Systems that work fine at sea level fail differently up here.
Our technicians are specifically trained for the climate challenges you face—not just cold winters, but the 5+ meters of annual snowfall, the temperature drops to -18°F or lower, and the dry summer heat that stresses cooling systems differently than humid climates. We service all HVAC brands, and we’re available 24/7 during extreme weather because that’s when systems fail most often.
You call or text (916) 519-1248 and describe what’s happening with your system. We ask a few questions to understand whether it’s an emergency or something we can schedule same-day.
If your heat’s out and it’s below freezing, we prioritize that. If your AC quit in July, same thing. We give you an arrival window and stick to it—no four-hour ranges where you’re stuck waiting.
When our technician arrives, they assess the system and explain what’s wrong in plain terms. You get upfront pricing before any work starts. No “we’ll see what we find” pricing that balloons into surprise fees.
If it’s a repair, we fix it and test the system to make sure it’s running correctly. If it’s a replacement, we walk through your options based on your home’s size, insulation, and how you use the space. We don’t upsell you into equipment you don’t need.
After the work’s done, we clean up and show you how to maintain the system between service visits. Then we follow up to make sure everything’s still working the way it should.

Every service call includes a full system diagnostic, not just a quick look at the obvious problem. We check airflow, refrigerant levels, electrical connections, thermostat calibration, and whether your ductwork is leaking conditioned air into your attic or crawlspace.
In South Lake Tahoe, CA, your outdoor unit deals with snow accumulation and ice buildup that most HVAC companies never encounter. We inspect for freeze damage, check drain lines that can freeze solid in winter, and make sure your defrost cycle is working correctly. These aren’t optional checks—they’re critical at altitude.
We also optimize your system for energy efficiency, which can cut your utility costs by up to 40%. That means adjusting airflow for Tahoe’s dry air, recalibrating thermostats for the temperature swings between day and night, and making sure your system isn’t oversized or undersized for your space.
You get transparent pricing before we start, licensed and insured technicians who show up when we say they will, and same-day service availability. If it’s an emergency—your heat fails when it’s 10 below, or your AC quits during a summer heatwave—we’re available 24/7.
We service all HVAC brands, so it doesn’t matter if you have a 15-year-old unit or something installed last year. And if you prefer texting to phone calls, that works too.
Full system replacements in South Lake Tahoe typically run between $12,000 and $18,000, depending on your home’s size, insulation quality, and whether you’re installing a furnace and AC or a cold-climate heat pump. That’s higher than it was five years ago—equipment costs have nearly doubled since 2019.
The altitude affects pricing because your system needs to be sized correctly for 6,200+ feet, where air density is lower and equipment works harder. Undersized systems will run constantly and fail early. Oversized systems will short-cycle and waste energy.
We give you upfront pricing after assessing your home. No “ballpark estimates” that turn into surprise fees later. And if your current system can be repaired instead of replaced, we’ll tell you that too—even if it means we make less money on the job.
Yes, but only if you install a cold-climate heat pump rated for subzero temperatures. Modern cold-climate models can deliver heat efficiently down to -22°F, and we don’t see temperatures that low in South Lake Tahoe very often.
The key is proper sizing. A heat pump that’s too small won’t keep up when temperatures drop below 10°F. One that’s too large will short-cycle and lose efficiency. We calculate heat load based on your home’s insulation, window quality, square footage, and how exposed your property is to wind.
Heat pumps also need to be installed with attention to snow accumulation around the outdoor unit. If snow blocks airflow or ice builds up on the coils, efficiency drops fast. We position units to minimize snow buildup and make sure your defrost cycle is calibrated correctly for Tahoe winters.
Your furnace might be running fine, but that doesn’t mean your system is efficient. The most common culprits are leaky ductwork, poor insulation, and thermostats that aren’t calibrated for Tahoe’s day-night temperature swings.
Leaky ducts are a big one. If your ductwork is in an unconditioned attic or crawlspace, you could be losing 30% or more of your heated air before it reaches your living space. That means your furnace runs longer to hit the thermostat setting, and your bill climbs.
We also see furnaces that are oversized for the home. An oversized furnace will heat your space quickly, shut off, then kick back on a few minutes later. That short-cycling wastes energy and wears out components faster. The fix isn’t always a new furnace—sometimes it’s ductwork repair, insulation upgrades, or recalibrating your thermostat to account for altitude and dry air.
Twice a year minimum—once before winter and once before summer. Tahoe’s extreme seasonal swings put more stress on your system than moderate climates, so skipping maintenance means you’re more likely to have a breakdown when you need heat or cooling most.
Before winter, we check your furnace’s heat exchanger for cracks, test the ignition system, inspect the blower motor, and make sure your ductwork isn’t leaking. We also check your outdoor unit if you have a heat pump, because snow and ice buildup will kill efficiency fast.
Before summer, we check refrigerant levels, clean the condenser coils, test the compressor, and make sure your thermostat is calibrated correctly. We also inspect your ductwork for leaks, because losing cool air in an unconditioned attic is just as wasteful as losing heat in winter.
Regular maintenance catches small problems before they become expensive failures. It also keeps your system running efficiently, which can save you hundreds of dollars a year on utility bills.
Call us immediately at (916) 519-1248. If it’s below freezing outside and you have no heat, that’s an emergency—we prioritize those calls and get someone to you as fast as possible, even if it’s the middle of the night.
While you’re waiting, check your thermostat to make sure it’s set to “heat” and the temperature setting is higher than the current room temperature. Check your circuit breaker to see if the furnace breaker tripped. If you have a furnace with a pilot light, check if it’s out.
If none of those fixes work, don’t try to troubleshoot further. Modern furnaces have safety shutoffs that prevent dangerous conditions, and overriding them or forcing the system to run can cause bigger problems. Space heaters can keep you warm temporarily, but don’t leave them unattended and keep them away from anything flammable.
We’ll diagnose the problem when we arrive, give you upfront pricing for the repair, and get your heat back on. If it’s a part that needs to be ordered, we’ll set you up with a temporary solution until the repair is complete.
Yes, and we recommend different maintenance schedules for vacation properties depending on how often you’re there. If your home sits empty for months at a time, your HVAC system faces different challenges than a year-round residence.
The biggest issue is freeze protection in winter. If you keep your thermostat set low to save energy while you’re away, your pipes and HVAC components are at risk if the system fails. We recommend setting the thermostat to at least 55°F and having someone check the property regularly during cold snaps.
We also see problems with systems that sit idle for long periods. Seals can dry out, refrigerant can leak slowly, and dust buildup can clog filters and coils. Before you arrive for the season, we can do a pre-occupancy check to make sure everything’s running correctly.
If you’re renting your property short-term, your system gets heavier use than a typical home because guests often adjust thermostats aggressively or leave windows open with the heat or AC running. That means more frequent filter changes and seasonal maintenance to catch problems before they become expensive failures.
