My husband and I chose Bull Mountain after interviewing four contractors. The other three estimators did not ask any questions nor give much information and on average the visit to my home was around twenty minutes.
BMountain was at my home for 90 minute asking questions about existing furnace and A/C--insulation of home--measured windows and noted direction each was facing. Troubleshooting about reasons for poor air flow in parts of the home--explained how the new flue would be installed for furnace and water heater. The list goes on. Very thorough and knowledgeable.
The fellows came to the house at the appointed time. Worked non stop on the days of install. Very pleasant and knowledgeable. We chose York for the furnace and A/C. We noticed a difference in the house cooling when we turned on the A/C and we hope to notice the house staying warm during the cold winter months.
