Helping this client with their main breaker
Chris Aguilar was personable, competent, and willing to answer questions. He changed our sub panel with no issues, and cleaned up well at the end of the job. Highly recommend the quality of work.
Good job
Love being in the meetings and learning something new everyday
Lack of communication between office and installers made for numerous visits with incorrect items for completion of the installation of fans and fire alarms. I am still waiting for the return of the spool of decorating chain that I purchased for the installation of the light fixture above the dining room table.
Alex did an amazing job explaining what went into the quote, showing where I needed things to be done, and made sure I understand every part of the project
Communications were excellent- from initial contact with the home office to scheduling and arrival of the technician. I was consistently notified via texts and emails. Eric was our tech for the first visit. He listened carefully to our issues, asked questions and explained what he was doing throughout the visit. A thorough circuit analysis suggested some significant issues that would indeed appear in the second visit. Eric suggested a plan for the second visit and again courteously explained all our options, and made it really easy to schedule the next visit. Very professional, efficient and patient with our questions.
Did great work and left a clean work area after. Very friendly group of people.

Whether you need AC repair, heating maintenance, or a brand-new system, we back every job with our Five Promise Guarantee. That means, if we don’t meet all five promises, your service is absolutely free. Thus, when Clayton homeowners search for reliable, honest, and high-quality HVAC service, they call us.
From that point on, I worked my way from digging trenches to running multimillion-dollar jobs and eventually leading entire departments. Over time, I came to realize that my deeper purpose wasn’t just about electrical work—it was about building lives. I began mentoring others who came from broken homes like mine, helping them become better people, stronger fathers, committed husbands, and effective leaders. In truth, that’s what continues to drive me: not just changing homes, but changing lives.
Meanwhile, the official brand was born through a partnership with Alexis and his father, Arturo—two men whose character and work ethic aligned perfectly with my vision for something greater than just another service company. Together, we laid the foundation for a values-driven business rooted in faith, family, and accountability. What started as a simple idea—do the job right and take care of people—evolved into 5 or Free Electrical Solutions, built on five non-negotiable promises to every customer. And most importantly, if we don’t keep all five, the job is free.
By 2025, our mission had grown—and so had our vision. 5 or Free Electrical Solutions officially expanded to become 5 or Free Electrical, Heating, and Air Solutions, offering the same values-driven service and bold guarantees to even more families across our region. More importantly, we made an even deeper promise to our team: to lead with consistency, offer second chances, and create an environment where people grow into who they were truly meant to be. In the end, we’re not just building a business—we’re building a brotherhood. Every job is an opportunity to serve, lead, and leave a legacy of trust and transformation.
Usually caused by low refrigerant, dirty coils, or clogged filters—getting your system diagnosed quickly can prevent long-term damage and restore comfort during summer months.
Faulty igniters, sensors, or burner problems are common winter emergencies for homeowners. Therefore, preventative maintenance and timely repairs reduce breakdown risk and keep your home safe and warm.
For example, banging, squealing, or rattling noises often indicate loose parts or motor failure. Ignoring these sounds can lead to costly repairs. Fortunately, a quick inspection often catches issues early.
Typically, this is caused by dirty filters, blocked vents, or a failing blower motor. As a result, you may experience uneven temperatures and increased energy bills. Technicians can help balance and restore airflow quickly.
If your system doesn’t respond to thermostat changes, it may be miscalibrated or have a dead battery. In many cases, a simple upgrade or reset restores control and improves efficiency.
Condensate drain clogs or cracked pans can cause pooling water. Left unchecked, this can lead to mold or water damage. Thankfully, it’s an easy fix when caught early.
Short cycling wears out your system and raises utility costs. Most often, it’s caused by dirty filters, refrigerant issues, or improperly sized systems. Proper diagnosis can resolve it quickly.
Musty, burnt, or chemical smells might signal mold, electrical issues, or gas leaks. Clearly, unpleasant odors should never be ignored—safety comes first.
Sudden energy spikes usually point to aging or inefficient systems. Consequently, regular servicing helps lower utility bills and extend your system’s lifespan.
Finally, this is the most proactive reason to call. Regular tune-ups help prevent breakdowns, preserve warranties, and ensure your system runs efficiently all year long.
We believe in clarity and transparency. Here are common HVAC repair and installation questions our Livermore customers ask. Backed by our 5-Promise Guarantee, you can count on honest answers and dependable service.
AC repairs typically range from $150–$600 depending on the part or issue. We provide honest, upfront pricing and no hidden fees.
Most companies charge a $75–$150 diagnostic fee, which may go toward the repair if you proceed. We’re transparent with all costs.
Repairs are often cheaper, but units over 10 years old may be more cost-effective to replace long-term. We help you weigh the options.
Refrigerant leaks and compressor issues are among the most common. Routine maintenance can help avoid major breakdowns.
The compressor can cost $1,000 or more to replace. We’ll help you determine whether repair or replacement is your best investment.
Most AC units last 10–15 years with regular tune-ups. We recommend annual maintenance to extend lifespan and performance.
Insurance typically doesn’t cover wear-and-tear. Damage from covered events like storms may qualify. We can help you evaluate coverage.
Costs range from $4,000–$7,000 depending on efficiency, brand, and complexity. We offer free estimates to help plan your budget.
Most repairs take 1–3 hours. Our technicians are equipped for fast, accurate repairs—often the same day you call.
Most do charge a service call fee. We always make sure you understand what’s included before any work begins.
Repairs in California generally range from $150–$1,000. We offer competitive rates and stand behind our 100% satisfaction guarantee.
