Dear Neighbors, Thank you for the Central AC Recommendations. So many people asked me to share the information I received. So here it is: *METRO HEATING & COOLING* · Metro heating and cooling carries Carrier products and we just got ac two weeks ago. Great experience. We have heard that Beam is the cheapest option but they didn't carry Carrier product. I think Lennox only. · Metro is great. May be a bit more but worth it. Call Mark. · Try Metro Heating-- they did a great job on my house · Metro Heating and Cooling. Excellent. *ROMEA & SON HEATING & AIR CON* · I have used Romea & Son Heating and Air conditioning and have been very pleased with them. They replaced my AC compressor (the unit outside) when it died a couple of summers ago, and I've also had them to the house to service the furnace in the winter. They are located in Glenshaw, just a few miles north of Highland Park. http://www.romeahvac.com/ *TUDI* · We used Tudi and had a good experience. · We've had good experiences with Tudi Mechanical for HVAC systems. *Dongilli Heating and Air Conditioning* - dongilliheating@gmail.com · Lisa his wife will likely respond. They are amazing. Very clean, polite, and attentive. *Economy H&C* · I used Economy H&C, and I would use them again. *Diggins Heating & A/C* · I have a GREAT recommendation for you. His name / company is Jack Diggins. Diggins Heating & A/C, 5150 Baptist Road, Pgh, 15236. (412) - 882 – 4428. He put central air in my Highland Park home in the early 2000s and his work is the best in the business. He works also with lots of contractors who have him work in their own home! The wife of one of them recommended him to me. My home has radiator heat & it was a real project for me to find someone who could do properly this type of installation. He is a very, very nice man -- extremely competent along with any crew and reasonably priced. You'll not find better. *Arch Moore HVAC* · Gary Moore, of Arch Moore HVAC, did the installation and excellent maintenance for 2 of my homes. High integrity, high competence. He now works with another company on installations but does the all important maintenance himself. *Tedesco heating & cooling* · Tedesco heating & cooling. Local family business 412-441-7747 *Wade Heating & Cooling* · did a good job for me, about a dozen years ago now. *RESTANO* · Restano and were very happy with them. *Alpha to Omega HVAC* · We used Alpha to Omega HVAC and Building SolutionsAnthony is meticulous and INCREDIBLY detailed. *NOT RECOMMENDED*: Sullivan
