How to Reduce Winter Heating Costs in Long Beach

Long Beach, California, is known for its mild coastal climate, where winters are typically cool but rarely freezing. Yet, despite the relatively temperate weather, many residents still experience noticeable spikes in their utility bills during the colder months. This is often due to outdated heating systems, poor insulation, inefficient thermostat use, or misconceptions about what “cold” means in a maritime environment. Reducing winter heating costs in Long Beach isn’t about braving subzero temperatures—it’s about optimizing comfort with minimal energy waste. With smart upgrades, behavioral adjustments, and localized strategies tailored to Southern California’s unique climate, homeowners can cut heating expenses by 20–40% without sacrificing warmth or convenience. This guide provides a comprehensive, step-by-step roadmap to help Long Beach residents lower their winter heating bills while maintaining a comfortable indoor environment.

Step-by-Step Guide

1. Conduct a Home Energy Audit

Before making any changes, it’s essential to understand where your home is losing heat. A professional energy audit can identify air leaks, insufficient insulation, and inefficient HVAC components. Many utility providers in California, including Southern California Gas Company (SoCalGas), offer free or low-cost home energy assessments. These audits typically include a blower door test, infrared thermal imaging, and duct leakage evaluations. Even if you don’t hire a professional, you can perform a basic DIY audit by walking through your home on a windy day with a lit incense stick or candle. Watch for smoke drifts near windows, doors, electrical outlets, and baseboards—these indicate air infiltration points. Document all areas of concern so you can prioritize repairs.

2. Seal Air Leaks Around Windows and Doors

One of the most cost-effective ways to reduce heating costs is sealing gaps where cold air enters and warm air escapes. In Long Beach, older homes often have single-pane windows and worn weatherstripping that compromise energy efficiency. Use weatherstripping tape or adhesive-backed foam strips along door frames and window sashes. For larger gaps, apply caulk around stationary window frames, baseboards, and where pipes or wires enter the home. Pay special attention to attic hatches and crawl space entrances—these are frequently overlooked but major sources of heat loss. A $20 investment in weatherstripping and caulk can yield a return of 10–20% in heating savings over a single winter season.

3. Install or Upgrade Window Coverings

Windows are the weakest thermal barrier in most homes. During the day, open south-facing curtains or blinds to allow passive solar heating. At night, close heavy curtains, thermal window treatments, or insulated shades to trap heat inside. Cellular (honeycomb) shades are particularly effective—they create air pockets that act as insulators. For a budget-friendly alternative, hang thermal-lined curtains or even a simple quilt or blanket behind existing drapes. In Long Beach, where winter days are often sunny, maximizing solar gain during daylight hours and minimizing heat loss at night can reduce reliance on mechanical heating by up to 15%.

4. Optimize Your Thermostat Settings

Thermostat management is one of the most powerful levers for reducing heating costs. The U.S. Department of Energy recommends setting your thermostat to 68°F (20°C) during waking hours and lowering it by 7–10°F at night or when no one is home. In Long Beach, where nighttime temperatures rarely dip below 45°F, you can safely set your thermostat to 62–65°F while sleeping or away. Programmable thermostats automate this process, but even a manual adjustment of turning the heat down before bed and back up in the morning can save 10% annually. Consider upgrading to a smart thermostat like the Nest or Ecobee, which learn your habits and adjust settings automatically based on occupancy and weather forecasts. These devices often provide usage reports and energy-saving tips tailored to your region.

5. Maintain and Upgrade Your Heating System

Heating systems in Long Beach homes typically include gas furnaces, heat pumps, or electric baseboard heaters. If your furnace is over 15 years old, it likely operates at 60–70% efficiency. Modern high-efficiency models can reach 95%+ AFUE (Annual Fuel Utilization Efficiency). Replacing an old furnace with a new ENERGY STAR-certified unit can cut heating costs by 20–30%. Even if replacement isn’t feasible, annual maintenance is critical. Change your air filter every 1–3 months—clogged filters force your system to work harder. Have a licensed technician inspect your ductwork for leaks, clean burners, and check for carbon monoxide risks. In coastal areas like Long Beach, salt air can corrode components faster, making regular servicing even more important.

6. Use Ceiling Fans to Circulate Warm Air

Warm air rises, which means your heating system may be warming the ceiling while your living space stays chilly. Most ceiling fans have a reverse setting (clockwise rotation) that gently pulls cool air upward and pushes warm air down along the walls. Run your ceiling fan on low speed in reverse during winter hours. This simple trick can make a room feel 3–4°F warmer without raising the thermostat. In Long Beach homes with high ceilings—common in mid-century modern and craftsman-style houses—this technique is especially effective.

7. Insulate Attics, Walls, and Floors

Proper insulation is the backbone of energy efficiency. The U.S. Department of Energy recommends R-30 to R-60 insulation levels for attics in California’s climate zones, which includes Long Beach (Zone 3). If your attic has less than 12 inches of insulation, adding more can significantly reduce heat loss. Blown-in cellulose or fiberglass is cost-effective and can be installed over existing material. For walls, consider spray foam or blown-in insulation if you’re doing renovations. In homes with raised foundations, insulating the underside of the floor with rigid foam boards or fiberglass batts prevents cold air from seeping up from crawl spaces. Many California residents qualify for rebates through the California Energy Commission’s Home Energy Renovation Opportunity (HERO) program or local utility incentives.

8. Reduce Phantom Loads and Use Efficient Lighting

While not directly related to heating, reducing overall energy consumption helps lower utility bills. Incandescent and halogen bulbs generate heat, but they’re inefficient and contribute to unnecessary energy use. Replace them with LED bulbs, which use 75% less energy and last 25 times longer. Unplug devices like TVs, chargers, and coffee makers when not in use—“phantom loads” can account for up to 10% of household electricity use. Smart power strips automatically cut power to idle devices, making this process effortless. Lowering your total energy demand reduces strain on your heating system and may even lower your gas bill if you’re on a bundled utility plan.

9. Utilize Zone Heating Strategically

Instead of heating your entire home, focus warmth on occupied rooms. Close doors to unused bedrooms, offices, or guest rooms. Use portable space heaters only in frequently used areas like the living room or home office—but never as a primary heat source. Choose models with thermostats, tip-over protection, and automatic shutoff features. In Long Beach, where winters are short and mild, zone heating allows you to keep your main living areas cozy while letting less-used spaces cool down naturally. This approach can reduce heating costs by 25% or more, especially in larger homes.

10. Take Advantage of Natural Heat Sources

Long Beach enjoys over 280 sunny days per year, even in winter. Use sunlight to your advantage. Open curtains on south-facing windows between 9 a.m. and 3 p.m. to capture free solar heat. Dark-colored floors or rugs absorb and retain heat better than light-colored ones. Avoid placing furniture or drapes in front of windows that receive direct sunlight. If you have a fireplace, ensure it’s properly sealed when not in use—open chimneys can draw warm air out of your home. Consider installing glass fireplace doors to retain heat while still enjoying the ambiance.

Best Practices

1. Avoid Cranking the Heat Too High

Many people believe turning the thermostat way up will heat the house faster. It doesn’t. Your furnace delivers heat at a fixed rate. Setting it to 78°F won’t warm your home quicker than 68°F—it will just run longer and waste energy. Resist the urge to overheat. In Long Beach, 68–70°F is more than sufficient for comfort during the day.

2. Don’t Turn Off Heat Completely

While lowering the thermostat saves money, turning it off entirely can cause pipes to freeze in rare cold snaps or promote mold growth from condensation. Maintain a minimum of 60°F in unoccupied rooms to protect your home’s structure and air quality.

3. Keep Vents and Registers Clear

Blocking vents with furniture, rugs, or curtains restricts airflow and forces your system to work harder. Ensure at least 12 inches of clearance around all heating registers. In older homes, some vents may be closed off due to renovations—reopening them can improve system balance and efficiency.

4. Monitor Humidity Levels

Dry air feels colder than moist air. In winter, indoor humidity often drops below 30%, making you feel chilly even at 68°F. Use a hygrometer to track humidity and aim for 40–50%. Adding a humidifier—especially a whole-house model integrated with your HVAC system—can make you feel warmer without raising the thermostat. Humid air also reduces static electricity and improves respiratory comfort.

5. Use Cooking and Showering Wisely

Leaving the oven door open after baking, running the dishwasher, or taking hot showers releases heat into your home. These activities can supplement your heating system during mild winter days. Open kitchen and bathroom doors after cooking or bathing to let warm, moist air circulate. Just be sure to use exhaust fans to prevent excess moisture buildup, which can lead to mold.

6. Plant Windbreaks and Use Landscaping Strategically

Outdoor elements affect indoor temperatures. Plant evergreen trees or shrubs on the north and northwest sides of your home to block cold winter winds. In Long Beach, native species like Coast Live Oak, Toyon, or Manzanita provide natural wind protection while enhancing curb appeal. Avoid planting tall trees directly in front of south-facing windows—they’ll block winter sun. Mulching around foundation plants also helps insulate the ground and reduce cold air infiltration.

7. Educate Household Members

Energy savings require consistent behavior. Teach children and roommates to close doors behind them, turn off lights, and avoid leaving windows open on cool days. Create a simple “Winter Energy Tips” chart and post it near the thermostat. When everyone participates, savings compound.

8. Schedule Seasonal Checkups

Treat your heating system like a car—regular maintenance prevents costly breakdowns. Schedule a professional inspection every fall before the cold season begins. Clean or replace filters, check for gas leaks, and ensure vents are clear. In coastal Long Beach, salt corrosion and humidity can degrade components faster than in inland areas, making seasonal tune-ups even more vital.

Real Examples

Example 1: The 1950s Ranch House

A homeowner in the Naples neighborhood of Long Beach lived in a 1,400-square-foot ranch home built in 1953. The house had single-pane windows, no attic insulation, and a 20-year-old furnace. Annual heating costs averaged $1,200. After conducting a free SoCalGas audit, they: sealed all window and door gaps ($75), added R-38 blown-in attic insulation ($1,200 with a $400 rebate), installed a programmable thermostat ($150), and replaced curtains with thermal-lined ones ($200). Within one winter, their heating bill dropped to $680—a 43% reduction. The insulation payback period was under two years.

Example 2: The Condo with Electric Baseboard Heat

A resident in a downtown Long Beach condominium relied on electric baseboard heaters, which cost $1,500 annually to operate. They couldn’t replace the system due to HOA rules. Instead, they: installed thick thermal curtains on all windows, used a smart plug to turn off heaters in unused rooms, placed rugs over cold tile floors, and used a small, efficient oil-filled radiator in the bedroom only. They also set their thermostat to 65°F at night. Their annual heating cost fell to $820—a 45% savings—without any major renovations.

Example 3: The Multi-Generational Home

A family in the Los Altos area owned a 2,800-square-foot home with an old gas furnace and poor duct sealing. They had elderly parents who preferred higher temperatures. To balance comfort and cost, they: sealed ducts with mastic sealant ($300), added a smart thermostat with zoning capabilities ($700), installed ceiling fans in all bedrooms, and used space heaters only in the parents’ room. They also set the main thermostat to 66°F and kept the guest wing at 62°F. Their annual heating bill dropped from $2,100 to $1,300, and the elderly family members reported improved comfort due to more even heat distribution.

Example 4: The Coastal Bungalow with Salt Air Damage

A homeowner in the Bluff Park area noticed their furnace was cycling more frequently and making strange noises. A technician found corroded burners and leaky ducts due to salt-laden air. They replaced the furnace with a high-efficiency model and sealed all ducts with aluminum tape and mastic. They also installed a whole-house humidifier to counteract dry air from the heater. Their energy bill dropped 32%, and the furnace has run reliably for three winters since.

FAQs

Is it cheaper to leave the heat on all day in Long Beach?

No. It’s more efficient to lower the thermostat when you’re asleep or away. Modern heating systems are designed to reheat spaces quickly without excessive energy use. In Long Beach’s mild winters, the temperature drop overnight rarely exceeds 10–15°F, so your system won’t need to work overtime to recover.

Do I need to replace my windows to save on heating?

Not necessarily. While new double-pane windows improve efficiency, sealing leaks and adding thermal curtains can achieve 70–80% of the same benefit at a fraction of the cost. Replace windows only if they’re cracked, fogged, or drafty despite weatherstripping.

Can I use a space heater instead of turning up the furnace?

Yes—but only as a supplement. Space heaters are efficient for heating small, occupied spaces but are expensive to run as a primary heat source. Use them in one room while keeping the rest of the house cooler. Always choose models with safety certifications and never leave them unattended.

Why is my heating bill high even though Long Beach winters are mild?

High bills usually stem from poor insulation, air leaks, or an inefficient system. Even in mild climates, heat escapes quickly through windows, walls, and ducts. Many homes in Long Beach were built before modern energy codes, so retrofitting is often necessary.

Are there rebates for installing insulation in Long Beach?

Yes. California offers rebates through the California Energy Commission and local utilities. SoCalGas and LADWP may provide up to $1,000 for attic, wall, or floor insulation depending on your home’s size and current R-value.

How often should I change my furnace filter?

Every 1–3 months, depending on usage and air quality. In coastal areas, dust and salt can clog filters faster. Check monthly and replace when visibly dirty.

Does closing vents in unused rooms save money?

It can, but only if your system is properly balanced. Closing too many vents increases pressure in ducts, which can cause leaks or strain the blower motor. Use zoning systems or smart thermostats instead for better control.

Can solar panels help reduce heating costs?

Not directly, but they can reduce your overall electricity bill, which may include heating if you use electric heat pumps or baseboard heaters. Solar also increases your home’s value and may qualify for state tax credits.

Should I use a humidifier in winter?

Yes. Dry air makes you feel colder, so adding moisture can allow you to lower your thermostat by 1–2°F without discomfort. A humidifier also helps with skin and respiratory health during winter.

What’s the most effective single action to reduce heating costs?

Sealing air leaks and upgrading your thermostat. These two steps together typically deliver the fastest payback and highest savings for Long Beach homeowners.
