"Charlie and his crew arrived promptly at the time he mentioned over the phone. He and his crew are quiet team but went to work immediately. After about 45 minutes Charlie came down from the attic and described what he thought was the problem. He provided me with a ballpark quote for parts and labor. He needed to drive back to an HVAC parts distributer for a gas valve and circuit board. He and crew left for an hour and half and arrived back with the new parts. An hour later, my heating was back to working. I am typically skeptical of small business owners on providing quotes but Charlie came across as a competent technician with years of experience. I did not feel I was overcharged or misled. I will do business with Charlie and his crew again. My advice is be understanding of him and his crew's language barrier. Carefully explain details of your project experience and expected outcomes. Charlie will see to it that you are satisfied with his crew's work. Thanks Charlie!"

Central a/c service or repairs FAQs

In most cases, you’ll never need a recharge unless the system develops a leak. If that happens, expect to top it off every two to three years—or sooner—until the leak is repaired. Keeping refrigerant at the right level lets your AC run efficiently and prevents extra wear on the compressor.

Plan on about 5 to 10 minutes per pound of refrigerant. Since each ton of cooling needs 2 to 4 pounds, a typical three-ton unit requires 6 to 12 pounds and roughly 30 minutes to 2 hours of work. Your tech will confirm the exact time once they know the size of your system and the amount of Freon it lost.

Skip the DIY. The EPA limits refrigerant sales and handling to certified technicians, and violators can face fines of up to $10,000. A licensed pro has the tools to find leaks, make repairs, and recharge the system safely. Hiring one keeps you on the right side of the law and protects your AC from costly mistakes.

Watch for ice on the evaporator coil, water pooling around the unit, frequent hissing, higher power bills, longer cooling cycles, or warm air from the vents. Spotting these red flags early lets you call a pro before efficiency drops and repair costs climb.

Coolant can escape when components crack or corrode, connectors loosen, factory defects slip through, or installation work leaves joints vulnerable. Years of vibration and wear also take a toll on seals and copper tubing. Because each cause calls for a different fix, let a licensed HVAC pro pin down the source and handle the repair.
