Job Locations and Reviews
Amazing electrician - actually assessed where the power short circuit stopped and determined the solution quickly. Would highly recommend asking for Eric to help you out diagnosing electrical problems
Very impressed that Eric not only assessed the short circuit by actually checking whether a breaker needed to be replaced or there was a short. He assessed that the light switch was incorrectly installed and fixed it. Very impressed on how he was able to figure it out
Tim was so very helpful. He went above and beyond the call.
I needed 6 wall mounted outside porch and garage lights installed plus an entryway Chandelier. Made an appointment for an estimate which was quick and easy to understand. About a week later the work was done in about 3 hours. Looking forward to calling Five or Free back for my next project!
My entire experience with Five or Free was incredibly positive, starting with the estimate by Alex, through the email communication to finalize the job, and finally through the incredible installation work by Tim. This company just hires really well and sets very high standards for themselves. I appreciate people that are experts at what they do and I will gladly go back and use Five or Free again.
Five or Free did an excellent job of modernizing the entire electrical system for my home. The system was customized to allow for all electronic devices in use. All components used ensured the system was as safe as could be. If I had a question, concern or request, they were quick to address them.
Angel came out to do a free consultation for me and was great to work with! Very kind and on time. If we do decide to get the work done we know which company to choose.

The Story of Concord’s Heating and Cooling Expert
A Chance That Changed Everything
Our story begins with second chances and strong foundations. At just 18 years old, I stood outside a job interview, tears in my eyes, sharing my truth with a man named Scott. I told him I had not grown up with my father, that my high school sweetheart was pregnant with our first child—who I was going to marry—and that I desperately wanted my life to change. I had just started going to church and was finally ready for something better. Thankfully, Scott gave me a shot in the trades, and that moment marked the beginning of a new life.

🔧 Top 10 Reasons Why Homeowners Call an HVAC Contractor in Concord
❄️ 1. AC Not Blowing Cold Air
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.
🔥 2. Furnace Not Heating
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.
🔊 3. Strange Noises
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.
🌬️ 4. Weak or Uneven Airflow
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.
📉 5. Thermostat Not Working
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.
💧 6. Water Leaks Around Unit
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.
🔁 7. System Constantly Cycling
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.
👃 8. Bad Smells From Vents
Musty, burnt, or chemical smells might signal mold, electrical issues, or gas leaks. Clearly, unpleasant odors should never be ignored—safety comes first.
📈 9. Higher Than Normal Energy Bills
Sudden energy spikes usually point to aging or inefficient systems. Consequently, regular servicing helps lower utility bills and extend your system’s lifespan.
🧰 10. Regular Maintenance & Tune-Ups
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.
