Report
I first came to know the people at Johnston furnace when they maintained the climate controls at the medical clinic I worked at. So I reached out to them for a quote for a new furnace. Their quote for a more efficient dual stage furnace was the same as others single stage. Plus they put me in contact with Veith duct cleaning who did a great job and they were $600 cheaper than wha the other furnace store wanted. They installed the furnace on time. They cleaned up after and I couldn't be happier.
