I had HHC install a fireplace for me in 2018. Brendan was very knowledgable and helped us select a fireplace that would meet our needs. The installation crew were awesome and left the house (interior/exterior) tidy.
Flash forward, and I had Brendan provide me a quote for an ac relocation. He provided a very competitive quote, but unfortunately the job could not be completed due bylaw concerns. Overall, I recommend HHC.
