After phone call Edward came next day and gave me quotation for equipment I needed, no gimmick just right for my house. I decided to go with AS because of the best warranty (10 year parts) including 5 years labour from CEM. Equipment was installed promptly 1 week after signing the contract. They even installed my smart thermostat I purchased earlier, free of charge. I am very satisfied from professional service CEM provided and would recommend them to all in HVAC need.
