Spring's Servicing & Heating Ltd

my furnace was not running normally in October; I called a small work shop I knew,I paid $330,but the result was the same as what I had tried;Because he was not a specialist for Carrier furnace.
I searched and called Springs Heating to get a quote ,David the technician,came and checked that the secondary heat exchange had to be replaced, estimate cost was about $540. He was nice and skillful ,he spent 30 mins and made the furnace temporary working costed $136.
3 days later,Jeff came with the new part,he spent 2½hr taking every things apart,well done! costed $600.fair price.I highly recommend Springs Heating for the team service ! They are the Professional!
