Jones Services is now a NO CONTACT service company. Our plumbers, electricians and HVAC technicians are running NO CONTACT service calls. We literally stand in different rooms than our customers, emailing or reading out loud our findings. No handshakes, no paperwork, not even allowing customers to touch iPads. Our technicians wear disinfected gloves, use disinfected tools and whip down anything their gloves and tools touch after servicing equipment. We practice NO CONTACT at work now too. Technicians are not allowed in the office, equipment and parts are delivered to their trucks in the parking lot. Only one employee per vehicle. All company meetings are conducted via Zoom. Most office personal are working from home. Those in the office work apart from each other. No one wants to be quarantined with their toilets backing up, without water or electricity or heat or hot water and now without air conditioning or air filtration or air purification. We are doing everything we can to help all our employees stay health to protect ourselves and our customers.

"Val S did a fantastic job. He quite me on several options and decided to go with what suited me best. He was professional and courteous."

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.
