Precision Heating & Air installed my furnace and they did a really good job. They were very good. They replaced an old furnace and I thought they were very efficient and very professional- I couldn't have asked for more. They cleaned up after themselves and were very polite and respectful. The installers were knowledgeable and they seemed like nice people. They put in a new furnace and replaced a cruddy old furnace. It seems to work pretty well. They came out regularly to do check-ups and do regular maintenance, and their prices are reasonable. The first time I used them, I chose them because of the good prices they were offering and I liked what I saw, so I went with them.
