Tips for Reducing Your Cooling Costs in Dixon, Woodland, and the Entire Bay Area
Keeping your home cool during a Vallejo summer doesn’t have to drain your wallet. With rising energy prices across the Bay Area, homeowners in Fairfield, Solano, and beyond are seeking innovative ways to reduce their cooling costs without compromising comfort.
How to Keep Cool and Save Money This Summer
Here are our top tips to help you save money and energy this summer:
- Adjust Your Thermostat
Set your thermostat as high as you’re comfortable with — ideally around 78°F when you’re home and even higher when you’re away. If you live in Napa or Martinez, where evenings can cool down significantly, consider turning the AC off at night and opening windows instead.
- Seal Up Your Home
Gaps and leaks around doors, windows, and ducts let cool air escape and hot air in. Weatherstripping and caulking are affordable ways to improve efficiency. In older homes, sealing up can save you quite a bit on monthly bills.
- Block Out the Sun
Keep blinds or curtains closed during the hottest parts of the day to reduce solar heat gain. In homes with large windows, investing in thermal curtains or window film can make a noticeable difference.
- Use Fans Strategically
Ceiling fans help circulate cool air, making your home feel up to 4 degrees cooler. Just remember to turn them off when you leave the room — they cool people, not air. You can also set your fan to rotate counterclockwise in the summer, which pushes cool air down into the room more effectively. In homes without ceiling fans, portable fans placed near windows in the evening can help draw in cooler Bay Area night air while exhausting warm air out.
- Keep Up With HVAC Maintenance
A dirty, neglected AC works harder and costs more to run. Changing your filters, cleaning around your outdoor unit, and scheduling a professional tune-up with A-1 Guaranteed Heating & Air, Inc. will help your system run more efficiently throughout the summer.
- Consider an Upgrade
If your system is more than 10–15 years old, it may be time to upgrade to a high-efficiency unit. Many Bay Area homeowners are surprised to learn how much they can save — and don’t forget to ask us about available energy rebates in Vallejo and surrounding areas to help offset the cost.

Your Summer HVAC Maintenance Checklist for Vallejo and the Bay Area
When summer arrives in Woodland, Fairfield, Benicia, and the rest of the Bay Area, your air conditioner becomes your best friend. However, to keep it running efficiently and avoid surprise breakdowns during a heatwave, it’s crucial to stay on top of HVAC maintenance.
At A-1 Guaranteed Heating & Air, Inc., we’ve put together a summer HVAC maintenance checklist tailored to Bay Area homeowners to help you keep your system in peak shape all season long and avoid emergency breakdowns.
Summer Maintenance Checklist for Cooling Systems
✔️Change or Clean Your Air Filters
The simplest — yet most often overlooked — task is replacing or cleaning your air filters. Dirty filters restrict airflow, causing your system to work harder and increasing energy costs. For homes in Vallejo or Martinez with higher levels of dust or pollen, you may need to replace your filter more frequently during the summer months.
✔️Clean Around Your Outdoor Unit
In places like Napa or American Canyon, where trees and shrubs abound, leaves, grass, and debris can quickly build up around your outdoor condenser unit. Ensure there are at least two feet of clear space around the unit to allow for proper airflow and reduce strain on the system.
✔️Check Your Thermostat
Verify that your thermostat is functioning correctly and programmed for summer efficiency. Upgrading to a smart thermostat can save you money by automatically adjusting temperatures when you’re away — a great option for tech-savvy Bay Area homeowners.
✔️Inspect Ductwork for Leaks
Leaky ducts can waste a significant amount of cooled air, especially in older homes found throughout Fairfield and Dixon. Look for visible gaps, or consider hiring a professional to inspect and seal your ductwork for improved efficiency.
✔️Schedule a Professional HVAC Tune-Up
While DIY steps are helpful, nothing replaces a professional HVAC maintenance service. Our technicians at A-1 Guaranteed Heating & Air, Inc. perform a comprehensive checkup that includes cleaning coils, checking refrigerant levels, tightening electrical connections, and other necessary maintenance tasks.
Why Regular Maintenance Matters
Regular HVAC maintenance ensures your system operates efficiently, reduces your energy bills, and prolongs the life of your equipment. Plus, you’ll catch potential issues early before they turn into costly repairs on a scorching summer day.

6 Tips to Choose the Right HVAC System for Your Home: A Guide for Bay Area Homeowners
When it comes to comfort, few things matter more than your home’s HVAC system. Whether you’re building a new house or replacing an outdated unit, choosing the right heating and cooling system is one of the most important decisions you’ll make. At A-1 Guaranteed Heating & Air, Inc., we’ve helped thousands of families throughout Dixon, Woodland, and the Bay Area find the perfect HVAC systems for their homes—systems that are reliable, energy-efficient, and tailored to their needs.
If you’re not sure where to start, here’s a comprehensive guide to help you make the best choice.
1. Understand the Types of HVAC Systems
Before choosing a new HVAC system, it’s important to understand the main types available:
- Split Systems: These include an outdoor unit (air conditioner or heat pump) and an indoor unit (furnace or air handler). They are the most common option for homes in Solano County.
- Heat Pumps: Ideal for the Bay Area’s mild climate, heat pumps provide both heating and cooling in one energy-efficient unit.
- Ductless Mini-Splits: These systems are perfect for homes without ductwork or for adding HVAC to new additions or specific rooms.
- Packaged Systems: Best for homes with limited indoor space, all components are housed in a single outdoor unit.
If you’re unsure which type is right for you, our HVAC installation team in Vallejo can assess your home and offer personalized recommendations.
2. Evaluate Your Home’s Size and Layout
One size does not fit all when it comes to HVAC systems. A unit that’s too small will struggle to keep your home comfortable, while one that’s too large can lead to high energy bills and humidity problems.
A professional load calculation—available through A-1 Guaranteed Heating & Air, Inc.—takes into account your home’s square footage, insulation, window placement, ceiling height, and more. This ensures you get a system that’s properly sized for your home in the Bay Area.
3. Prioritize Energy Efficiency
California homeowners are always looking for ways to reduce energy consumption and save on utility bills. Choosing an energy-efficient HVAC system is a great place to start.
Look for systems with high SEER (Seasonal Energy Efficiency Ratio) and AFUE (Annual Fuel Utilization Efficiency) ratings. Energy Star® certified equipment can also offer long-term savings and may qualify for local rebates or tax incentives.
Need help navigating the best efficiency options? Our heating and cooling experts in Solano County will walk you through the benefits and potential savings of each system.
4. Consider Smart Technology
Modern HVAC systems come with a variety of smart features to enhance your comfort and convenience:
- Programmable thermostats allow you to set temperature schedules to save energy when you’re not home.
- Zoning systems enable different parts of your house to be heated or cooled independently.
- Wi-Fi control lets you manage your system remotely using your smartphone or tablet.
At A-1 Guaranteed, we specialize in installing smart HVAC systems throughout Vallejo and nearby areas, helping you stay connected to your home’s comfort, even when you’re away.
5. Think Long-Term Maintenance and Reliability
When investing in an HVAC system, think beyond the initial cost. Regular maintenance can extend the life of your system, improve its performance, and lower repair costs over time.
Choose a system from a trusted brand, and make sure you’re working with licensed HVAC contractors in the Bay Area who offer ongoing maintenance plans. A-1 Guaranteed Heating & Air, Inc. proudly offers HVAC service agreements to customers throughout Solano County, ensuring their systems stay in peak condition year-round.

Top 10 HVAC Myths Debunked: Insights for Bay Area Homeowners
From Vallejo to Dixon and all the areas in between, a misunderstanding of HVAC systems causes many homeowners in the Bay Area to waste energy, incur unnecessary expenses, or unintentionally reduce the lifespan of their equipment. At A-1 Guaranteed Heating & Air, Inc., we are committed to equipping customers with the proper knowledge they need to keep their homes as comfortable as possible without wasting energy or money.
Let’s clarify the top 10 HVAC misconceptions and set the record straight!
Myth 1: Bigger HVAC Systems Are Always Better
Truth:
Many think a bigger system will more effectively heat or cool their home. However, an oversized system is likely to short cycle (turn on and off quickly), leading to inconsistent temperatures and excessive wear on components. A properly sized system will function more efficiently, provide consistent comfort, and lower energy costs. At A-1 Guaranteed, we conduct precise load calculations to ensure that each system is sized and laid out to match the specific needs of your home.
Myth 2: Closing Vents in Unused Rooms Saves Energy
Truth:
This approach can negatively affect your HVAC system. Contemporary systems are engineered for optimal airflow distribution across the house. Shutting vents raises the air pressure in the ducts, potentially leading to leaks, ineffective functioning, and even damage to the equipment. Rather than closing vents, consider investing in a zoned HVAC system or a programmable thermostat that can adjust comfort levels without placing excessive strain on your system.
Myth 3: You Only Need to Change Your Filter Once a Year
Truth:
In the Bay Area, where wildfires and high pollen counts are seasonal concerns, filters often need to be changed far more frequently, sometimes monthly. A dirty filter restricts airflow, forcing the system to work harder and decreasing indoor air quality. We recommend checking your filters regularly and replacing them every 1 to 3 months, depending on your home’s air quality and usage levels.
Myth 4: Setting the Thermostat Lower Cools Your Home Faster
Truth:
Your HVAC system delivers air at a constant rate. Cranking the thermostat way down doesn’t speed up cooling; it only makes the system run longer. This drives up energy costs without added comfort. A programmable or smart thermostat, professionally installed by us, can help optimize temperature changes without wasting energy.
Myth 5: HVAC Maintenance Isn’t Necessary Unless Something’s Broken
Truth:
Waiting until your system breaks down can be costly and inconvenient, especially during peak summer or winter days. Preventive maintenance keeps your HVAC running efficiently, reduces breakdowns, and prolongs system life. A-1 Guaranteed offers affordable maintenance plans that include inspections, tune-ups, and early detection of issues.
Myth 6: Ceiling Fans Lower Room Temperature
Truth:
Ceiling fans don’t actually lower the temperature; they make you feel cooler by creating airflow over your skin. They’re a great supplement to your AC but shouldn’t be relied on alone. In Vallejo’s mild spring and fall seasons, using ceiling fans along with your HVAC system can help you set your thermostat a few degrees higher without sacrificing comfort.
Myth 7: Thermostat Placement Doesn’t Matter
Truth:
The placement of your thermostat has a huge impact on system performance. Installing it in direct sunlight, near a drafty window, or beside a kitchen can result in inaccurate readings and unnecessary system cycling. Our technicians at A-1 Guaranteed know where to position thermostats for maximum accuracy and comfort.
Myth 8: Duct Tape Is a Reliable Fix for Duct Leaks
Truth:
Despite the name, duct tape doesn’t hold up well on HVAC ductwork. Over time, it dries out and peels off. Instead, HVAC pros use specialized mastic sealant or UL-listed metal foil tape for long-term sealing. Our ductwork repair services in Vallejo use only code-compliant, durable materials that improve airflow and efficiency.
Myth 9: You Can Install Your Own HVAC System
Truth:
DIY installation may be cost-effective, but HVAC systems involve gas lines, electrical wiring, refrigerants, and precise airflow calculations. Improper installation can void warranties, decrease efficiency, and even become a safety hazard. At A-1 Guaranteed Heating & Air, Inc., our NATE-certified technicians ensure that every installation meets local codes and manufacturer specifications.
Myth 10: Running the HVAC Continuously Is Bad for the System
Truth:
Your HVAC system is designed to operate continuously for extended periods of time. It’s often more efficient to run longer cycles than to stop and start repeatedly. Short cycling puts more wear on parts and uses more energy. A properly sized and maintained unit should run steadily to maintain the desired temperature without harm. Ask us how to balance run-time with zoning and smart controls.
