"Expertly. The latest ATL cold snap killed my decades old hot water pump when I merely switched my thermostat from Cool to Heat. Common sense drew me to search the internet's reviews for Plumbers near me with the highest rated reviews. Weather Masters was an obvious choice and I have been very impressed with how quickly I was made to feel that I was now their #1 priority. Recognizing my dilema, they worked fast, as we were mere hours before a busy holiday week. I then asked if they might also examine my old rusting A/C unit. At the time of this review, everything has been completed. I am so happy I called Weather Masters. Their work was expertly done, all was performed on my schedule, and most important, was reasonably priced. When working with Weather Masters it was quickly apparent that Jason and Robert's years of experience and practical know how unquestionably contributes daily to Weather Masters operation and outstanding professional results. Thank you so much Kristen*, James, Jason, Robert, Tony, Brian, Jose and Traci, to name a few.

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.
