When your AC quits during a 105-degree afternoon or your furnace stops working on a cold January morning, you need someone who shows up fast and fixes it right. Not someone who drags it out or hits you with surprise charges after the fact.
That’s what you get with a local HVAC contractor who knows Sacramento County’s climate. Systems that cool efficiently when it’s triple digits outside. Furnaces that handle our damp winter mornings without cycling on and off constantly. Equipment sized correctly so you’re not paying for wasted capacity or dealing with hot spots in your home.
Most homeowners we work with see energy savings between 20-40% after proper system optimization. That’s because incorrectly sized units and neglected ductwork don’t just make your home uncomfortable—they cost you real money every month. When your system is running the way it should, you feel it in your comfort and see it in your utility bills.
Hot & Cold HVAC started because too many people in Sacramento County were getting burned by overpriced service and technicians who didn’t understand local climate challenges. We’re not a franchise. We’re licensed, insured, and based right here.
Our technicians are trained specifically for the conditions you deal with—extreme summer heat that pushes systems to their limits, Delta breeze patterns that affect humidity, and seasonal wildfire smoke that impacts indoor air quality. We serve both Sacramento and Placer counties, and we’ve seen what works and what doesn’t in Walnut Grove and surrounding areas.
You can reach us by text at (916) 519-1248, and we offer same-day service when you need it. We don’t play games with pricing, and we don’t upsell you on equipment you don’t need.
You call or text us at (916) 519-1248, and we’ll ask a few questions about what’s going on with your system. If it’s an emergency, we prioritize same-day service. If it’s maintenance or a new installation, we schedule a time that works for you.
When we arrive, we diagnose the issue and give you transparent pricing before any work starts. No hidden fees. No surprise charges after the fact. If it’s a repair, most jobs are completed within hours. If you need a new system, we’ll walk through your options, explain what makes sense for your home and budget, and handle the installation professionally.
After the work is done, we test everything to make sure it’s running efficiently. You’ll know exactly what was done, why it was necessary, and what to expect moving forward. If you have questions later, you can reach us directly—not a call center.

We handle everything from emergency HVAC repair to full system installations. That includes all major brands, whether you have a Carrier, Trane, Lennox, or something else. If it heats or cools your home, we work on it.
In Walnut Grove and the surrounding Sacramento County area, summer temperatures regularly exceed 100°F. That means your AC is working harder and longer than systems in milder climates. We check refrigerant levels, inspect ductwork for leaks, clean coils, and make sure your system is sized correctly for your home. Undersized units can’t keep up. Oversized units cycle too frequently and waste energy.
Winter brings cool, damp mornings and occasional tule fog. Your furnace needs to handle humidity without short-cycling or creating uneven heating. We inspect heat exchangers, test safety controls, and optimize airflow so you’re not dealing with cold spots or high gas bills.
SMUD offers rebates up to $3,000 for gas-to-electric heat pump conversions and $1,000 for electric-to-electric upgrades. Heat pumps are extremely efficient in Sacramento’s climate and can cut your energy costs significantly. We’ll walk you through what qualifies and how to apply.
We offer same-day service for most emergency calls in Walnut Grove and Sacramento County. When you contact us, we’ll ask about your situation and prioritize based on urgency—like if your AC is out during a heat wave or your furnace stopped working overnight.
Most repairs are completed within a few hours of arrival. We stock common parts on our trucks, so we’re not making multiple trips or leaving you without heating or cooling while we order something. If we need a specialty part, we’ll let you know upfront and give you a realistic timeline.
During extreme weather, call volume goes up. If we can’t get to you the same day, we’ll be honest about timing and do everything we can to get you scheduled as soon as possible. You can reach us by phone or text at (916) 519-1248.
We give you transparent pricing before we start any work. You’ll know exactly what the repair or installation costs, with no hidden fees or surprise charges after the fact.
For repairs, the cost depends on what’s wrong—a simple fix like replacing a capacitor is different from a compressor failure. For new installations, pricing depends on the size of your home, the type of system you choose, and whether ductwork needs modification. We’ll walk through your options and explain what makes sense for your budget and comfort needs.
Sacramento County homeowners who optimize their systems typically save 20-40% on energy costs. That’s real money every month, especially during summer when your AC is running constantly. We’ll also let you know if you qualify for SMUD rebates, which can offset upfront costs significantly—up to $3,000 for heat pump conversions.
If your system is under 10 years old and the repair cost is reasonable, fixing it usually makes sense. If it’s older than 15 years, breaking down frequently, or the repair cost is more than half the price of a new system, replacement is often the better move.
We’ll be straight with you about what we find. If your compressor failed on a 20-year-old unit, we’re not going to sell you a $2,000 repair when you’d be better off replacing it. On the other hand, if your system is relatively new and just needs a part, we’ll fix it and get you back up and running.
Older systems are also less efficient. If your AC or furnace is from the early 2000s, a new high-efficiency system could cut your energy bills by 30% or more. We’ll show you the numbers so you can make an informed decision, not a pressured one.
We service all major HVAC brands—Carrier, Trane, Lennox, Goodman, Rheem, Bryant, Amana, and more. If it heats or cools your home, we work on it.
Some companies only service the brands they sell, which leaves you stuck if you have a different manufacturer. We’re not tied to one brand, so you’re not limited in your options. Whether you need a repair on your current system or want to install something new, we’ll recommend what actually works best for your home and budget.
Our technicians are trained on the specific challenges of Sacramento County’s climate. That means we know how systems perform when it’s 110°F outside or when humidity from the Delta affects indoor air quality. Brand matters less than proper installation, correct sizing, and regular maintenance.
Sacramento County has extreme temperature swings and unique climate conditions that put more stress on HVAC systems than milder areas. Summer temperatures regularly hit 100-110°F, which means your AC runs longer and works harder. That increases wear on components and drives up energy costs if your system isn’t optimized.
Winters bring cool, damp mornings and tule fog, which affects humidity levels inside your home. Your furnace needs to handle that moisture without short-cycling or creating uneven heating. Seasonal wildfire smoke also raises concerns about indoor air quality, which is why proper filtration and ventilation matter more here than in other regions.
Systems that work fine in moderate climates often struggle in Sacramento County. Undersized units can’t keep up during heat waves. Oversized units cycle too frequently and waste energy. Ductwork that isn’t sealed properly loses 20-30% of conditioned air before it even reaches your rooms. We size, install, and maintain systems specifically for the conditions you deal with here.
Heat pumps are extremely efficient in Sacramento County’s climate. They provide both heating and cooling, and because our winters are mild, they don’t struggle the way they do in colder regions. You get year-round comfort with lower energy costs compared to traditional gas furnaces and AC units.
SMUD offers rebates up to $3,000 for gas-to-electric heat pump conversions, which helps offset the upfront cost. Most homeowners who switch see around $500 per year in energy savings, and that number goes up if you’re replacing an older, inefficient system. Heat pumps also reduce your carbon footprint, which aligns with SMUD’s goal to electrify 154,000 homes by 2030.
The key is proper sizing and installation. A heat pump that’s too small won’t keep up during a 105-degree day. One that’s too large will cycle inefficiently and cost you more to run. We’ll assess your home, explain your options, and install a system that actually works for Walnut Grove’s climate—not just what’s on sale.
