Introduction
Heating and cooling account for nearly half of a typical home’s energy bill in the Dallas-Fort Worth area, and for commercial buildings, the percentage can be even higher. With North Texas weather swinging from scorching summers to unpredictable cold snaps, it’s no wonder that keeping your home or business comfortable can put a dent in your budget.
The good news? You don’t need to sacrifice comfort to save money. By making a few strategic changes, both in how you use your HVAC system and in maintaining it, you can lower your utility bills, extend your equipment’s lifespan, and improve overall comfort year-round.
Below are practical, proven strategies from the team at Spencer Air Conditioning & Heating, who have been helping DFW residents and businesses save money since 1960.
1. Schedule Regular HVAC Maintenance
Think of HVAC maintenance like an oil change for your car, it keeps things running smoothly and prevents costly breakdowns. When your system is tuned up regularly by a professional, it operates more efficiently, meaning it uses less energy to keep you comfortable.
For homeowners, maintenance means fewer surprise repairs and lower monthly bills. For business owners, it means avoiding downtime, maintaining consistent indoor comfort for employees and customers, and avoiding big repair costs that eat into your budget.
Our recommendation: Schedule maintenance twice a year, once in the spring for your cooling system and once in the fall for your heating system.
2. Seal and Insulate Your Space
Air leaks are silent money-drainers. If conditioned air escapes through cracks around windows, doors, and ductwork, your HVAC system works harder to compensate, driving up costs.
- Common leak points in North Texas homes: Attics, garage doors, recessed lighting, and poorly sealed duct joints.
- In commercial buildings: Gaps in rooftop units, unsealed windows, and doorways that see frequent use.
Adding insulation in your attic and sealing ductwork can dramatically reduce energy waste. The U.S. Department of Energy estimates that proper insulation and sealing can cut heating and cooling costs by up to 20%.
3. Upgrade to a Programmable or Smart Thermostat
A programmable thermostat lets you set different temperatures for different times of the day. A smart thermostat goes a step further, learning your habits and adjusting automatically for maximum efficiency.
For DFW’s climate:
- Summer: Set your thermostat to 78°F when you’re home and 85°F when you’re away.
- Winter: Set it to 68°F when you’re home and drop it to 60–62°F when away or asleep.
For businesses, programmable settings can ensure comfort during business hours while avoiding waste when the building is empty.
4. Change Air Filters Regularly
This simple step is often overlooked but has a big impact. A clogged air filter forces your system to work harder, increasing energy usage and reducing air quality.
In dusty Texas conditions, especially if you have pets or run a business in a high-traffic area, you may need to change filters every 1–2 months.
Pro tip: Keep a few spare filters on hand so you’re never tempted to put it off.
5. Improve Airflow and Zoning
Balanced airflow ensures that every room gets the right amount of heating or cooling. If some rooms are always too hot or too cold, your system may be struggling to distribute air evenly, wasting energy.
For larger homes or commercial buildings, a zoning system can be a game-changer. By dividing the property into zones with individual temperature control, you can heat or cool only the spaces in use, reducing waste.
6. Consider Energy-Efficient Equipment
If your system is more than 10–15 years old, it may be costing you more than you realize. Today’s high-efficiency HVAC units can reduce energy consumption by 20–40% compared to older systems.
While there’s an upfront investment, the long-term savings, combined with potential utility rebates, can make upgrading a smart financial decision. Plus, newer systems tend to run quieter and provide more consistent comfort.
7. Use Energy-Saving Habits
Small behavioral changes add up over time:
- Ceiling fans: In summer, run them counterclockwise to push cool air down; in winter, reverse to circulate warm air.
- Window treatments: Keep blinds closed on hot afternoons to block heat. In winter, open them during sunny days to let warmth in.
- Nighttime adjustments: Lower the heat slightly at night in winter or raise the cooling temperature at night in summer.
These habits cost nothing but can contribute to noticeable monthly savings.
Your Comfort and Your Budget Can Coexist
Cutting your heating and cooling costs isn’t about drastic sacrifices, it’s about making smart, strategic choices. By combining regular maintenance, smart technology, proper insulation, and a few habit changes, you can keep your space comfortable year-round without overspending.
