Ryan came to my home to evaluate our system and give an estimate for replacing a 16 year old heating/cooling system. We had agreed through communiques via Angie's List messaging that he would come between 1pm and 3pm. He called about 20 minutes before his arrival and did arrive within the arranged time at about 1:20. After examining the unit with me, he agreed that the system had exceeded its life expectancy and before he worked up a quote for replacing it Ryan offered to perform a test to determine if the system would qualify for Gulf Power's current rebate incentives. He offered to do this free of charge and began the test; however, after several minutes he informed me that the system was dangerously low on freon and that the test results were not acceptable unless the freon levels were raised. I balked because first of all I knew about the leaks and hesitated at charging a leak riddled unit and second, because I had heard quotes anywhere from $94 to $104 per pound for this older type freon. Ryan sympathized and offered to charge only 40 dollars per pound warning that without it the unit would be apt to freeze up. I consented, partly since there would be no one at home in the next 24 to 48 hours to notice if it were to freeze up and call for service, and partly because it seemed that the test for qualifying for rebates couldn't be completed otherwise. The test results did determine that the unit qualified for the Gulf Power rebate incentives and Ryan wrote up quotes for four different options, two being 13 SEER rated 5 ton heat pumps and two being 15 SEER rated 5 ton heat pumps. His quotes were significantly less expensive than competitors but we have not made a final decision on whom to use. I just want to remark that Ryan was courteous, professional, informative (answered my many questions knowledgeably and patiently and thoroughly) and respectful.
