Not only did he show up on time but took his time to service and repair my unit. Greg is knowledgeable, efficient and thorough in handling the job.

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.

"HVAC service was amazing from Jones Service. From start to finish everything was perfect. The price was very competitive. Love their work."
