Hear from our Happy Customers

Superior service! Had the office follow up on my Lennox rebates when they hadn’t gone through. Nice to see service past just the install of the equipment! Thanks!!

The team at Tartan were great to deal with. Would highly recommend to anyone requiring installations or service!
