How to Lower Your Heating and Cooling Bills Without Sacrificing Comfort

How to Lower Your Heating and Cooling Bills Without Sacrificing Comfort

If you’re like most Chicago homeowners, you’re always looking for ways to save on energy costs—especially during our sub-zero winters and humid summer heatwaves. The good news? You don’t have to give up comfort to cut down your energy bills.

In this guide, Shavitz Heating and Air Conditioning shares simple, effective ways to reduce your heating and cooling expenses while keeping your home comfortable all year long.

1. Your Air Filter Might Be Working Against You

Your air filter is supposed to catch dust, dirt, and allergens before they spread through your home—but when it’s clogged or overdue for a change, it can actually make things worse. A dirty filter restricts airflow, reduces system efficiency, and can even cause dust to circulate more, not less.

Even worse? It forces your HVAC system to work harder, which means higher energy bills and more wear and tear over time.

HVAC Filter Tips

• Change your filter regularly—usually every 1 to 2 months, depending on usage, pets, and allergies.
• Choose the right filter for your system: one that balances filtration and airflow (not all filters are created equal!).
• Stay ahead with seasonal maintenance to keep everything clean and running smoothly.

Want better performance and cleaner air? Consider upgrading to a Dynamic electronic air cleaner—it captures smaller particles than standard filters and puts less strain on your system

2. Seasonal HVAC Tune-Ups: A Small Step That Saves Big

Just like your car needs oil changes, your HVAC system needs regular tune-ups to stay in top shape. Skipping seasonal maintenance can lead to lower efficiency, uneven temperatures, surprise breakdowns—and higher energy bills.

A well-maintained system runs smoother, lasts longer, and is far less likely to leave you sweating (or freezing) when you need it most.

What a Shavitz Tune-Up Includes

• Coil cleaning for better airflow and heat transfer.
• Thermostat calibration for accurate comfort and control.
• Airflow checks to spot blockages or duct issues early.
• System safety inspection to keep your home protected.

We’ll make sure everything is running as it should—and catch small issues before they turn into costly repairs.

3. Seal Air Leaks and Insulate to Keep Comfort In

Even the most efficient HVAC system can’t keep up if your home is leaking air. Gaps around windows, doors, attic hatches—even outlets and recessed lights—let your heated or cooled air escape and force your system to work harder to maintain the temperature.

How to Improve Insulation

• Use weatherstripping or caulk to seal around windows and doors.
• Add insulation to attics, crawlspaces, or exterior walls.
• Consider an energy audit to find hidden leaks you might miss.

This one-time investment pays off year-round—and keeps your comfort level steady in every season.

4. Upgrade to a Smart Thermostat

Smart thermostats are a small change with a big payoff. They automatically adjust your home’s temperature based on your routine—lowering heat at night, raising it when you’re away, and optimizing comfort without you lifting a finger.

Bonus Features of Smart Thermostats

• Control from your phone.
• Energy usage reports.
• Learning algorithms to fine-tune your comfort.
• Maintenance alerts and filter change reminders.

Already have a programmable thermostat? A smart upgrade could give you even more savings.

5. Don’t Let Ductwork Drain Your Energy

You could be losing up to 30% of your system’s energy through leaky or poorly insulated ducts—especially if they run through attics, basements, or crawlspaces.

If certain rooms always feel too warm or too cold, your ducts could be the reason.

Ductwork Energy Tips

• Schedule a duct inspection to look for leaks or airflow issues.
• Have ducts sealed and insulated to reduce energy loss.
• Consider airflow balancing or a zoning system for better temperature control.

6. Upgrade to a High-Efficiency HVAC System

If your system is 12–15 years old (or older), it may be costing you more than you think. Today’s high-efficiency furnaces and AC units use significantly less energy—and they’re better at maintaining even temperatures throughout your home.

Benefits of Upgrading Your HVAC Include:

• Lower energy bills.
• Quieter, more consistent comfort.
• Compatibility with smart thermostats and zoning.
• Improved airflow and humidity control.

We’ll help you determine if it’s time to upgrade—and find a system that fits your needs and budget.

7. Balance Indoor Humidity

Humidity plays a huge role in how warm or cool your home feels. Too much moisture in summer can make the air feel sticky and warm. Too little in winter makes the air feel colder than it is—and dries out your skin and sinuses, too.

How to Improve Humidity Control

• Keep indoor humidity between 40% and 60%.
• Use a whole-home humidifier in winter and a dehumidifier in summer.
• Check your system’s settings to make sure it’s managing humidity effectively.

8. Keep Vents and Registers Clear

It might sound basic, but blocked vents can throw off your whole system. Furniture, curtains, or rugs covering supply or return vents can restrict airflow, make your system work harder, and lead to uneven temps.

HVAC Vent Tips

• Keep vents open and uncovered.
• Vacuum vent covers regularly.
• Don’t close vents in unused rooms—it disrupts system balance and can increase pressure.

9. Set Smart Temperature Goals

Small thermostat changes can lead to noticeable savings over time. Instead of cranking the heat or AC, aim for reasonable, consistent settings.

Thermostat Energy Saving Tips

• 68°F in winter when you’re home.
• Set to 76°F in summer.
• Drop it a few degrees at night or when you’re away to save even more.

Even just 1–2 degrees can make a difference on your bill!

10. Join a Maintenance Plan

If you’re trying to get the most life and efficiency out of your HVAC system, a maintenance plan is the way to go.

Here’s what you get with a Shavitz Comfort Plan:

• Regular inspections
• Filter changes
• Priority scheduling
• Discounts on repairs
• Peace of mind, all year long
