How to Maximize Your Air Conditioner’s Efficiency During Vacaville’s Hot Summers
Handling Your Home Comfort Needs in Winters, CA

Summers in Vacaville, CA bring the heat—and your air conditioner is working overtime to keep your home comfortable. But if your system isn’t running efficiently, you could be losing cool air and watching your energy bills climb.
The good news? You can improve performance and save money with a few smart adjustments. At Pearce Heating & Air Conditioning, we help Vacaville homeowners get the most out of their cooling systems. Here’s how you can keep your AC running strong all summer long.
Schedule Seasonal AC Maintenance
Before peak temperatures hit, schedule a professional Vacaville AC tune-up. A neglected system is more likely to break down, consume excess energy, and struggle to cool your home evenly.
At Pearce Heating & Air Conditioning, we perform a comprehensive inspection and service of your system, including:
- Checking refrigerant levels
- Cleaning condenser coils
- Testing airflow and thermostat function
- Inspecting and tightening electrical connections
Routine maintenance can extend the life of your unit and reduce the risk of costly repairs when you need cooling the most.
Replace or Clean Your Air Filters
Your HVAC filter traps dust, pollen, and other debris, but when it gets clogged, it can restrict airflow and make your system work harder. That means higher energy bills and a greater chance of wear and tear.
In Vacaville’s dry and dusty climate, filters should be checked monthly and replaced every 1–3 months depending on usage. A clean filter means better airflow, improved indoor air quality, and a more efficient air conditioner.
Seal and Insulate Your Home
Cooling your home is only half the battle, keeping the cool air inside is just as important. Poor insulation and leaky ductwork allow conditioned air to escape, making your system work harder to maintain a consistent temperature.
Sealing windows and doors, insulating attics, and having your ductwork inspected by a professional can dramatically improve efficiency. At Pearce, we help homeowners pinpoint trouble spots and offer recommendations that pay off in comfort and energy savings.
Optimize Your Thermostat Settings
A few simple thermostat adjustments can significantly reduce your cooling costs. Set your thermostat to 78°F when you’re home and raise it to 85°F when you’re away to save energy.
Better yet, upgrade to a programmable or smart thermostat. These devices let you control your HVAC remotely, create automated schedules, and adjust settings based on your routine. Pearce Heating & Air Conditioning offers expert installation and setup so you can take full advantage of this technology.
Use Ceiling Fans Strategically
Ceiling fans don’t lower the room temperature, but they do help circulate cool air, making your home feel more comfortable. This allows you to raise your thermostat setting by a few degrees without sacrificing comfort.
Just remember: fans cool people, not rooms. Turn them off when you leave the room to avoid unnecessary energy use.
Block Out the Heat
Direct sunlight streaming through windows can heat your home quickly. Use blackout curtains, blinds, or reflective window film to minimize heat gain, especially during peak afternoon hours.
You can also plant shade trees or install exterior awnings to help keep your home naturally cooler. These passive cooling techniques complement your AC and reduce overall energy demand.
Consider Upgrading to a High-Efficiency AC System
If your air conditioner is more than 10–15 years old, it may be time for an upgrade. Older units tend to be less efficient and more prone to breakdowns, especially during extreme weather.
Modern ENERGY STAR®-rated systems use less energy, cool more effectively, and qualify for rebates or financing. Pearce Heating & Air Conditioning can help you evaluate your current system and recommend an upgrade that fits your home, budget, and comfort needs.
