"Easy to schedule home repair. Trainee Siraj completed repairs and system is back up. Repair van did not have 7uF capacitor which seems short=sighted. Paid premium for their trip to wholesaler to buy correct part. I was not given receipts for replaced parts. Also wish I had seen before/after weights on the refrigerant. At $120/lb, I would have appreciated the open books. Aside from sticker shock, happy overall with the work and happy to have A/C back."

"I had 12 different companies provide quotes, and these guys were by far the most affordable.

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.
