I was very happy with Argent Heating & Cooling – call Ron Gallant – 703-398-7006 or 703-281-6300. They just installed a new gas furnace & did extensive duct re-routing for a 3 story row house for $3,900.00 I didn’t need the AC done, but that would have been another couple of thousand.
I also have a proposal for a whole new system for a rental apt. – heat pump & all AC plus a crane to haul it to the roof – for $4,900.00.
I had another quote around that price point, but Ron took exceptional care to explain everything, offer various options and I never felt the “hard sell” of some other companies.
