"Contractor Recommendation: Norfolk County Heating & Cooling Our 1895 refurbished Victorian's 3rd-floor mini split unit needed repair. Leaking lines were replaced. A chemical reaction between the copper line and wrapped insulation caused pinhole leaks in the line set. Manufacturers recalled that the warranty had expired and the unit was cooling poorly. Four contractors were contacted for estimates. Owner Patrick and project supervisor Renato excelled. They quickly listened and explained the problem, process challenges, and possible solutions. The price given was accurate and a fraction of the others I received. That worried me until it became clear the other contractors had quoted outrageous pricesâ either their company was understaffed and didn't want the small project or thought the customer was ignorant. The other contractors pressured us to upgrade from line replacement to system overhaul. One refused to provide an itemized breakdown of the FIVE times Norfolk H&C estimate but continued contacting me to finalize the sale without changing the price or explanation. Renato visited the day before the appointment to take additional photographs and check his materials. On replacement/installation day, Renato and his assistant were punctual and polite, knocked and asked permission before entering the property, and were great to our small dog. They avoided disturbing a newly planted lawn and cleaned the house and area. Renato showed me the finished project, how he installed it, what he replaced, and its system testing. I highly recommend Norfolk County Heating & Cooling for any HVAC projectâ one of our most remarkable home contracting experiences."

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.
