Best Air Conditioner Tune Ups in Baltimore MD

didnt get a chance to write a review when Giovanni came out last Fall to tune up our heat pump and air handler for the winter but he is very knowledgeable and willing to answer any and all questions I have during the service. This time he came out to look at our heat pump which began clicking loudly for the past 3 days since we turned on the AC. Turns out the clicking was coming from the reversing valve because freon had leaked out to about 20% pressure when the norm should be 70%. He was patient to diagnose the problem and ultimately advised a new unit as the most cost effective solution since our unit used old R22 refrigerant so we'd have to replace in 2 years anyway. I was very satisfied with both service calls and would recommend Giovanni to anyone.My only annoyance is the inflated cost of parts Horizon is willing to charge, which is not a reflection on my review of Giovanni. However, to replace a capacitor for $266 when I can buy it on Amazon for $15 is outlandish
