I had Service Specialties Inc put in a furnace and air conditioner. Everything with the installation was fine and they have been running well. Their prices were reasonable and within market norms; they were neither cheap nor expensive and there was nothing unusual. The installers came on time, were clean and polite, and cleaned up after themselves. I had never used them before but a neighbor recommended them to me. I would go back to Service Specialties Inc again if I needed something in the future.
