Tim with Five or Free is amazing. He took the time to go over everything that he was doing and checked in through each phase of the project.

It's hard for me to summarize how great Tim is in a single review, so I'll probably send a letter later. Basically, he's an ACE and every encounter we have with him is top-notch. The level of service speaks to the culture of the company. Truly above and beyond. Gotta customer for life!

My old Juicebox charger gave out (and they are out of business). First, the response was fast! Carlos B (5 stars to him) carefully reviewed the charger setup, electrical panel, subpanel, and also checked some outlets in the house. They recommended a Grizzl-e, which I ordered. Once it arrived, I was able to get an install appointment within a few days. Then Damell K (5 stars to him!!) installed -- and discovered improper original installation and fixed it! Yes! 10 stars!!

SOLAR PROJECT HEROES We are trying to get Sunrun solar but we have to update our electric before Sunrun can proceed. We had Eric and Carlos come to our home today. They were one of 6 electricians that we had come look at our particular complex, 3 panel update. We knew is was a big job, and almost cancelled the appointment because everyone previous to them could not provide a written estimate, or could not properly identify the complete scope of the work. Eric pulled out a phone that had an application that allowed him to plug in all the parts and labor and we had an estimate for the work within 5 minutes. He then informed us that this estimate is their commitment to an accurate assessment, and should anything pop up along the way, they would take responsibility for that cost. The other piece to this project was that PG&E would need to be involved in approval and permitting. He said they handle all communication with PG&E and that the cost for permits was part of the estimate. This sweetened the deal because the estimate also came with zero interest financing. You can imagine the relief. Eric and Carlos were able to verbally paint a picture for us that they could handle the scope of the project from start to finish, with a dollar amount that wasn't going to get pushed, and the option for zero interest financing. We signed the contract on the spot. The contract gives us three days to pull out should our other parties decide they don't want to move forward. Conclusion, if you are trying to get solar before the end of the rebates and updating your system is required, Five or Free is fully prepared to make that project possible.

Why San Lorenzo Trusts Five or Free for Heating and Air Conditioning | Electrician Services

Is your AC struggling to keep up on warm afternoons? Lights flickering when you turn on appliances? When your home’s electrical or HVAC systems need attention, you want someone who knows San Lorenzo—not a random contractor sent from across the Bay.

Five or Free Electrical Heating & Air is your neighbor. We’ve been serving San Lorenzo and the surrounding East Bay communities for over 10 years, and we treat every home like it belongs to family.

We Know San Lorenzo—And We Know What Your Home Needs

San Lorenzo has a pioneering history that shaped American housing. Originally called “Squattersville” when settlers arrived during the Gold Rush in 1851, the community was renamed San Lorenzo—Spanish for “Saint Lawrence”—and became a thriving agricultural area with orchards and truck farms along San Lorenzo Creek.

Everything changed in 1944 when the David D. Bohannon Company, under contract with the U.S. Navy, began building San Lorenzo Village. This became one of the nation’s first planned communities—predating the more famous Levittown, Pennsylvania. Bohannon’s innovative pre-cutting techniques, called the “California method,” revolutionized home construction and were later used in developments across the country. The San Lorenzo Shopping Center was one of America’s first planned community shopping centers and became home to the very first Mervyn’s Department Store.

Today, San Lorenzo is home to nearly 30,000 residents. The homes here are largely from that historic 1940s and 1950s building boom—classic two and three-bedroom houses with character and charm. But those same homes often have electrical panels and HVAC systems that weren’t designed for modern demands. Between air conditioning, home offices, modern appliances, and the possibility of EV chargers, these older systems can struggle to keep up.

We’ve helped San Lorenzo homeowners upgrade their electrical panels, replace aging furnaces, and install efficient new AC systems. We understand what these mid-century homes need.

Your Local HVAC and Electrical Experts

We’re not some faceless corporation sending whoever’s available. When you call Five or Free, you get local technicians who know San Lorenzo’s neighborhoods and take pride in doing right by their neighbors.

Our team handles:

Panel upgrades for safer, more reliable power
AC repair, installation, and seasonal tune-ups
Furnace repair and heating system replacement
Ductwork installation and sealing
Smart thermostat setup
Indoor air quality solutions for healthier homes

Licensed, Insured, and Guaranteed

Every job we take on is backed by proper licensing, full insurance, and our “Five or Free” guarantee. We promise to do five things right on every service call. If we miss even one, your job is free.

That’s not a gimmick—it’s accountability. It’s how we’ve earned San Lorenzo’s trust for over a decade.

We’re Just Minutes Away

Quick Homeowner Tip:

Check your air filters every month. A clogged filter makes your HVAC system work harder, drives up energy bills, and shortens equipment life. And if you notice electrical warning signs like flickering lights, warm outlets, or burning smells—call a licensed professional right away.

Your Local Heating and Air Conditioning | Electrician, Lighting Contractor & Air Conditioning Contractor Serving San Lorenzo

Proud to Serve San Lorenzo for All Your Heating and Air Conditioning | Electrician Needs

San Lorenzo is a community with deep roots and historic significance. From its early days as farmland along San Lorenzo Creek to its transformation into one of America’s first planned communities, San Lorenzo has always been a place where hardworking families put down roots and build their lives.

The San Lorenzo Pioneer Cemetery tells the story of the community’s earliest settlers, including Moses Wicks, who brought oysters to San Leandro Bay. The historic First Southern Baptist Church, originally the Christian Union Society Church dedicated on July 4, 1875, still stands across the street. The San Lorenzo Unified School District, established in 1865, continues to serve local families today.

At Five or Free Electrical Heating & Air, we’re proud to keep this historic community comfortable year-round.

San Lorenzo’s Climate and Your Home’s Systems

San Lorenzo enjoys a mild Mediterranean climate typical of the East Bay. Summer highs typically reach the mid-to-upper 70s, with July often being the warmest month—occasionally reaching around 79°F during warmer stretches. Unlike the hotter inland valleys, San Lorenzo’s proximity to the Bay keeps temperatures moderate.

Winters are cool and damp, with highs in the mid-to-upper 50s and lows in the low-to-mid 40s. Morning fog is common, rolling in from the Bay and keeping things cool until it burns off. The community receives about 18-19 inches of rain annually, mostly between October and April.

That moderate climate is relatively easy on your AC, but your heating system still puts in work during those cool, foggy mornings from fall through spring. And San Lorenzo’s historic housing stock—largely built during the 1940s and 1950s—often has electrical panels and HVAC systems that weren’t designed for today’s efficiency standards or modern electrical demands.

Your Neighbors in HVAC and Electrical Services

Whether you’re shopping at the San Lorenzo Village shopping center, enjoying one of the community’s parks, or simply relaxing at home in your classic mid-century house—you deserve a home that’s comfortable and safe.

That’s what Five or Free delivers. Reliable service from a local team that knows San Lorenzo and the entire East Bay.

Complete Heating and Air Conditioning | Electrician Services in San Lorenzo, CA

Why call three different companies when one team can handle it all? Five or Free Electrical Heating & Air delivers full-service HVAC and electrical solutions to San Lorenzo homeowners—all under one roof.

Electrical repairs and troubleshooting
Panel upgrades for San Lorenzo homes
Whole-home rewiring

Lighting consultant and lighting contractor services for indoor and outdoor projects
Electric vehicle charging station contractor—Level 2 home charger installation

San Lorenzo’s homes were largely built in the 1940s and 1950s during the Village development. That means most have older electrical systems—often 60-amp or 100-amp panels—that weren’t designed for today’s demands. Between air conditioning (which many original homes didn’t have), modern appliances, home offices, and EV chargers, these older panels often need upgrades. Our electricians specialize in bringing these classic homes up to modern safety standards.

Air conditioning repair service and AC installation
Furnace repair and heating system replacement

Many San Lorenzo homes weren’t originally built with central air conditioning—it simply wasn’t common in the 1940s. If your home has had AC added over the years, or if you’re still relying on window units, we can help you upgrade to a modern, efficient system that keeps your entire home comfortable.

Why Choose One Company for Everything?

Your home’s electrical and HVAC systems are connected. Your AC needs proper electrical support to run efficiently. Your furnace depends on safe wiring. When one team understands both sides, you get faster diagnostics, better repairs, and fewer headaches. That’s the Five or Free difference.

Frequently Asked Questions (FAQs) About Heating and Air, Electrician Services, Electrical Installation Service, and Heating contractor

Here are the answers to some of our customers’ most frequently asked questions (FAQs) about . If you can’t find the answer you’re looking for, please feel free to contact us.

Frequently Asked Questions About Appliance Wiring in San Lorenzo, CA

Here are the top questions our San Lorenzoneighbors ask about safely connecting their major household appliances.

Why do new appliances require specialized Appliance wiring in San Lorenzo, CA?New appliances like electric dryers, ovens, and cooktops draw significantly more power (often 240V and higher amperage) than standard outlets. Specialized Appliance wiring in San Lorenzo , CA, involves installing a dedicated circuit and the correct high-amperage receptacle to prevent dangerous overloads and potential fires.
My circuit breaker keeps tripping when I run the washing machine. Is this a sign I need new Appliance wiring?Yes, frequent tripping is a strong indication that the existing circuit is undersized or shared with too many other devices. Professional Appliance wiring will install a dedicated, appropriately sized circuit for the washer, resolving the overload issue.
Does Appliance wiring in San Lorenzo, CA, include installing the correct 240V outlet for an electric vehicle (EV) charger?While EV chargers are not typical kitchen/laundry appliances, the process is similar. Appliance wiring involves the necessary dedicated 240V circuit and connection for both kitchen/laundry equipment and high-power devices like EV chargers, which we regularly install.
How can I ensure my new kitchen appliances are covered by their warranty during Appliance wiring installation?Most appliance warranties require installation by a licensed professional. Using Five or Free for Appliance wiring in San Lorenzo, CA, ensures that your new oven, range, or cooktop is connected safely, correctly, and according to manufacturer specifications, protecting your warranty investment.
Is it safe to use an extension cord for a refrigerator or freezer if I don’t have the correct Appliance wiring?No. Extension cords are highly discouraged for major appliances as they can cause overheating, voltage drop, and fire hazards. We recommend upgrading your Appliance wiring to ensure a dedicated, correctly grounded outlet is installed for refrigerators and freezers.
Can you install a new GFCI outlet as part of the Appliance wiring for a dishwasher or disposal in my San Lorenzo kitchen?Yes. Code requires that electrical circuits serving dishwashers, garbage disposals, and counter-top appliances in proximity to water be protected by GFCI (Ground Fault Circuit Interrupter) outlets. We include this crucial safety feature in our Appliance wiring in San Lorenzo, CA, services.

Heating and Air Conditioning Questions

How often should I change my air filter?

For most San Lorenzo homes, we recommend checking your filter monthly and replacing it every 30 to 90 days. If you have pets or allergies, change it closer to every 30 days. A clogged filter restricts airflow, makes your system work harder, increases energy bills, and shortens equipment life.

Why is my AC running but not cooling my San Lorenzo home?

Several issues could cause this—low refrigerant, a dirty condenser coil, frozen evaporator coils, a failing compressor, or leaky ductwork. When summer temperatures climb into the upper 70s, your AC works to keep up. If your system is blowing warm air or can’t maintain comfortable temperatures, call Five or Free for a diagnosis before a small problem turns into a major repair.

How long do HVAC systems typically last?

Most air conditioners and furnaces last 15 to 20 years with proper maintenance. San Lorenzo’s mild, Bay-influenced climate is easier on equipment than extreme environments, which can help extend system life. However, age still takes its toll. If your system is over 10 to 15 years old and needing frequent repairs, it may be more cost-effective to replace it with a newer, energy-efficient model. Our team at Five or Free can help you weigh repair versus replacement options.

Should I repair or replace my HVAC system?

A common rule in the industry is the “$5,000 rule”—multiply the age of your system by the cost of the repair. If the total exceeds $5,000, replacement usually makes more sense. Other factors include how often it’s breaking down, rising energy bills, and whether your San Lorenzo home stays comfortable. At Five or Free, we give honest assessments—we won’t push a replacement if a repair makes more sense for your situation.

What temperature should I set my thermostat to save energy?

San Lorenzo’s mild climate means you won’t need extreme settings. During warmer months, setting your thermostat to 72-76 degrees when you’re home works well. In winter, 65-68 degrees is comfortable for most households. We also install programmable and smart thermostats that adjust automatically based on your schedule—a great way to save energy when you’re at work or away.

Why is my furnace making strange noises?

Different noises mean different problems. Banging or popping often indicates ductwork expanding and contracting. Squealing can signal a worn blower belt or motor issue. Rattling may mean loose components. And a grinding noise usually points to a serious motor problem. Don’t ignore unusual sounds—they typically get worse and more expensive to fix. Call Five or Free to have it inspected before you’re left without heat on a cool, foggy San Lorenzo morning.

How often should I have my HVAC system serviced?

We recommend twice a year—once in spring before warmer weather and once in fall before heating season. Regular maintenance keeps your system running efficiently, catches small problems before they become big repairs, and extends equipment life. Five or Free’s tune-ups include inspecting all components, cleaning coils, checking refrigerant, and testing system performance.

Still have questions about heating, cooling, or electrical services in San Lorenzo? Call Five or Free Electrical Heating & Air—we’re always happy to help.
