The copper Freon lines were purged and filled with chlorine-free Freon. Additional attic insulation was brought to 10+ inches. As a part of the purchase, a three year preventive maintenance agreement was concluded.. The agreement includes 2 complete inspections per year. We received a product registration confirmation originally submitted to Maytag by Bayside Heating and Air Conditioning. All necessary work permits were obtained by Hillsborough Building Services Division. County inspection occurred 3/12/2014 and was approved at time of inspection. The entire process was conducted with professionalism, competency and outstanding customer service. The company called 8/2014 and scheduled the first detailed inspection. The outdoor condenser unit, indoor unit/blower, surge protection, air purifier, attic insulation and ducts overall condition was good. The system was operating within manufacture specs. The system is very quiet and runs less often than the old system. The air purification system works well. The company and product are both the best!
