We had Comfort central install a new Mini-Split system in our cottage as well as service the existing unit in our house. On both occasions the workers were exactly on time despite the early hour. I am very technically minded so I could appreciate their professionalism, knowledge of the product (even before the sale was concluded) and neatness (shoe protectors, tarp on the ground, sweep after themselves and not a single scuff mark on the walls or the floor). In addition, they work very well as a team, even under very adverse conditions - South side in full sun on a 90 degree day - and they are every funny with each other yet most respectful with me, the client, answered every question thoroughly and knowledgeably. I recommend them without any reservation at all and, even though I could have possibly paid less elsewhere I am glad that I chose them.
