Why Your Heating Bill Is Skyrocketing And What To Do About It

By Posted on

A heating bill that keeps climbing is more than an inconvenience—it’s a sign something isn’t right. Maybe your system is working harder than it should. Maybe your home isn’t holding heat the way it used to. Either way, no one should have to choose between staying warm and keeping costs under control.

1. Your Heating System Is Working Too Hard

A well-tuned system should heat your home without draining your wallet. If yours is constantly running, it’s burning through energy—and your budget. Older units lose efficiency over time, and even newer systems struggle if something’s off, like a clogged filter or leaky ductwork.

How to Fix It:

  • Schedule a winter HVAC checkup to ensure your system runs at peak efficiency.
  • If your system is over 12 years old, it might be time to upgrade to a high-efficiency Trane, Bosch, or Mitsubishi system.
  • Consider a geothermal system for long-term savings.

2. Heat Is Escaping Through Your Home

A drafty home forces your system to work overtime. Warm air escapes through gaps in doors, windows, and poorly insulated spaces, leaving your heating system to make up the difference.

What You Can Do:

  • Seal gaps around windows and doors to lock in warmth.
  • Add insulation in attics and crawl spaces for better heat retention.
  • Have us inspect your ductwork for leaks—losing warm air behind walls can be a hidden cost.

3. Your Thermostat Settings Are Costing You

Keeping your thermostat set too high means your system never gets a break. Small adjustments can make a big difference on your monthly bill.

Better Settings for Efficiency:

  • Set the temperature at 68°F during the day and lower at night.
  • Upgrade to a smart thermostat to automate adjustments.
  • Keep temperature changes minimal—constantly raising and lowering the heat forces your system to work harder.

4. Dirty Filters and Blocked Vents Are Restricting Airflow

A heating system needs proper airflow to function efficiently. When filters are clogged or vents are blocked, your furnace has to work harder to push warm air through your home.

What to Check:

  • Replace air filters every 1-3 months during heating season.
  • Make sure furniture or rugs aren’t blocking vents.
  • Schedule a system checkup to ensure everything is running as it should.

5. Your System Needs Regular Maintenance

Heating systems aren’t built to run indefinitely without attention. Even the best equipment needs seasonal maintenance to perform well and last longer. A neglected system works harder, runs longer, and costs more to operate.

How to Stay Ahead of Problems:

  • Book a winter heating checkup before the coldest months hit.
  • Join our maintenance plan to ensure year-round efficiency.
  • Let us handle the details—so you don’t have to worry about surprise breakdowns.

6. Dry Air Is Making Your Home Feel Colder

When indoor air is too dry, it makes your home feel chillier than it actually is. That often leads to cranking up the heat unnecessarily.

A Simple Fix:

  • Use a humidifier to keep indoor air at 30-50% humidity.
  • Have us assess your indoor air quality to find the right balance for your home.

7. Your System Might Be the Wrong Size

A heating system that’s too small for your home will run constantly, driving up energy costs. One that’s too large cycles on and off frequently, wasting energy.

How to Know If Your System Is the Right Fit:

  • If your heat never seems to reach the right temperature, your system may be undersized.
  • Frequent short cycling means your system may be too large.
  • We can perform a load calculation to determine the best system for your home.
