I was at the heating and cooling store the other day looking for a part for my fireplace and I asked them to have someone come out and price a HVAC system for my home. I told them I wanted to get an idea on cost as the system is from 1984 (Van Halen anyone). I have a forced air nat gas system and A/C which is Heil. The guy came and looked at it and said $8,000 to change it to all electric system, heat pump and no gas back up. They would have to wire in 3, 60 amp breakers he said and our box had the room for it. I for sure want an all electric system as for the past 4 years we have not used the furnance much at all and it is my understanding heat pumps are cheaper to run for A/C. This seemed high to me but I have never dealt with a furnace,A/C replacement. He said of course to wait until this system fails. Our home is just shy of 1,500 sq ft. OUr current energy cost around $1K year and we use no gas other than for the furnace which is current turned off(gas meter). I suspect our biggest electric load is the water heater. Last months bill was $74 Is there a general place to find out more about the effeicency of different heating and cooling systems out their on the market? This place was selling Lennox. Maybe the price is not out of line but seemed high to me. He said something like 15 sear effeciency? Not sure about what all that means.
