We feel the job by Chris and Don was done well and professionally.They were efficient and helpful in answering our questions and concerns.Except for a couple of screws that were left on the floor and rug they,easy to miss, cleaned up the work area very well. Stu,the tech who came later to check everything out and make sure the job was done completely and properly was also professional,though he told us some things differently than Chris and Don. They told us to pour some vinegar into 2 of the pipes to clean them out after about a year,Stu said that was not necessary.Stu also removed the 2 batteries from the thermostat saying they were not needed since we were not going to program the thermostat.My wife and I thought that was just a bit confusing. Over all though,they all did a fine and professional job and made us feel good about our decusion to have Level replace our heating and AC units.The price was also as fair as could be expected. And,they showed up on time and when they said they would! Thank you!
