How to Keep Your Heating System Running Efficiently All Winter

December 08, 2025

Winter in Howell Township, NJ, can bring crisp mornings, freezing nights, and long stretches of cold weather. To stay comfortable, your home’s heating system works overtime—but that constant demand can strain efficiency and increase your energy bills if your system isn’t properly maintained.

Fortunately, a few practical steps can help your furnace, boiler, or heat pump run efficiently all season long. Here’s a detailed guide for Howell Township homeowners on how to maximize heating performance, reduce energy costs, and extend the lifespan of your system.

1. Schedule a Professional Heating Tune-Up

The first and most important step is scheduling annual maintenance before or at the start of the heating season.

A professional tune-up includes:

Cleaning burners, heat exchangers, and blowers.
Lubricating moving parts.
Inspecting gas connections and electrical components.
Testing safety controls and system efficiency.

For Howell Township residents, it’s best to book service in the fall, before the first deep freeze. Regular maintenance ensures the system is operating at peak performance, reduces the risk of mid-winter breakdowns, and keeps energy costs under control.

2. Replace or Clean Air Filters Regularly

Your heating system’s air filter plays a major role in both efficiency and indoor air quality. When filters become clogged with dust and debris, airflow is restricted—forcing the system to work harder to circulate warm air.

Best practices:

Check filters monthly.
Replace disposable filters every 1–3 months.
Clean reusable filters according to manufacturer instructions.

This small maintenance task can improve efficiency by up to 15%, extend system life, and help reduce allergens in your home’s air.

3. Seal Air Leaks and Insulate Your Home

Even the most efficient heating system will waste energy if warm air escapes through leaks or poorly insulated areas.

Focus on sealing gaps and cracks in:

Window and door frames.
Attics and basements.
Around utility openings and plumbing.

Add weatherstripping or caulk to problem areas, and consider adding insulation in attics, crawl spaces, and walls if they’re under-insulated.

For older Howell Township homes—especially those built before modern energy codes—proper sealing can dramatically improve comfort and reduce heating costs.

4. Keep Vents and Registers Clear

Blocked vents make your system work harder than necessary. Ensure that furniture, curtains, and rugs aren’t covering supply or return vents.

When airflow is restricted, heat cannot circulate evenly, causing hot and cold spots throughout your home. Keeping vents clear allows your system to maintain a consistent temperature more efficiently.

If your home still experiences uneven heating after clearing vents, it may be a sign of duct leaks or improper system balancing—issues that should be checked by a professional.

5. Optimize Your Thermostat Settings

Your thermostat directly influences how much energy your heating system uses. Even small temperature adjustments can have a big impact.

Energy-saving thermostat tips:

Set the thermostat to 68°F during the day when you’re home.
Lower it by 5–7 degrees at night or when away.
Use a programmable or smart thermostat to automatically adjust temperatures based on your schedule.

For every degree you lower your thermostat, you can save up to 3% on heating costs—without sacrificing comfort.

Smart thermostats also help Howell Township homeowners monitor energy use and adjust settings remotely, ideal for managing costs during cold snaps.

6. Ensure Proper Humidity Levels

Winter air is naturally dry, and running your heating system makes it even drier. Low humidity makes your home feel cooler, causing you to turn up the heat unnecessarily.

Adding a whole-home humidifier or portable units helps retain heat more effectively. Balanced humidity also reduces static electricity, protects wood furniture and floors, and improves indoor comfort.

Aim for indoor humidity between 30–50% for optimal results.

7. Check and Seal Ductwork

Leaky ducts are one of the most common causes of energy loss in central heating systems. Warm air escaping through gaps or poorly connected duct joints can reduce system efficiency by as much as 20–30%.

To fix this:

Inspect ducts for visible gaps or holes.
Use foil tape or mastic sealant to close small leaks.
Have a professional perform a duct pressure test for hidden leaks.

In homes with ducts running through unconditioned areas like basements or attics, insulating ductwork helps keep warm air from cooling before it reaches your living spaces.

8. Bleed Radiators and Check Boiler Pressure (If Applicable)

If your Howell Township home uses a boiler or radiator system, maintenance steps differ slightly.

Bleed radiators to release trapped air, ensuring even heating.
Check boiler pressure regularly; low pressure can reduce efficiency.
Inspect valves and connections for leaks.

A well-maintained hydronic system provides consistent comfort with minimal energy waste.

9. Use Ceiling Fans Strategically

Ceiling fans aren’t just for summer. By reversing their direction (so blades turn clockwise), fans gently push warm air down from the ceiling, improving circulation without increasing thermostat settings.

Running ceiling fans on low speed in occupied rooms can make your space feel warmer, allowing you to lower the thermostat slightly.

10. Keep Outdoor Units Clean and Clear

If you have a heat pump or hybrid heating system, don’t forget the outdoor unit. During winter, snow, ice, and debris can accumulate around it, restricting airflow.

Gently remove snow and leaves.
Keep at least two feet of clearance around the unit.
Avoid using sharp tools or pouring hot water on ice buildup.

A clear, well-ventilated unit operates more efficiently and avoids unnecessary strain on components.

11. Upgrade to an Energy-Efficient System

If your furnace or heat pump is more than 15 years old, replacement might be more cost-effective than continuing repairs. Modern ENERGY STAR® systems offer improved efficiency, variable-speed motors, and advanced controls that help regulate temperature more precisely.

Replacing an older system can reduce heating costs by up to 30%, while providing better comfort and reliability for Howell Township’s cold winters.

12. Schedule Regular Maintenance and Inspections

Preventive maintenance is the cornerstone of heating efficiency. Partnering with a trusted local HVAC provider ensures your system stays in top condition.

Professional maintenance typically includes:

Cleaning and testing components.
Checking safety features.
Monitoring performance metrics.
Identifying issues before they become emergencies.

For coastal regions like Howell Township, annual service also helps combat humidity and salt corrosion that can affect metal components.

Keeping your heating system running efficiently all winter in Howell Township, NJ, doesn’t require expensive upgrades—it’s about consistent care, smart usage, and a little preparation.

By sealing air leaks, maintaining clean filters, optimizing thermostat settings, and scheduling regular inspections, you’ll improve energy efficiency, save money, and ensure dependable warmth all season long.

Whether you rely on a furnace, boiler, or heat pump, these practical steps help extend your system’s life and keep your home comfortable through even the coldest New Jersey nights.
