We're going to be getting some estimates for geothermal for our house and I
wondered if anyone here could give an estimate I could use for reference
against the quotes I'll be getting. Here's our info:
Location: Northern Virginia, just north of Manassas, about 30 miles west of DC.
Heat range: As low as 6 deg in winter, to about 95 in summer.
House: Two story colonial with about 2400 sq ft. No basement, just a crawl
Current hvac: Central heating/cooling. Fairly new oil furnace (Armstrong Air
Ultra 80) and aging Ruud A/C.
We don't use the A/C that much, because we have installed fans in the kitchen,
bedroom, etc. We keep the house at about 70 deg in the winter.
Last heating season, we used about 900 gallons of oil (it was colder than
We have an acre and a half, so there's plenty of room to drill or trench.
Local dealers sell Waterfurnace and Econar.
Our main motivation is the price of heating oil contracts which went from
$1.25/gallon last year to $2.00 for this year. Probably be $3/gallon next year.
Any thoughts, suggestions, or rough guesses about what it would cost to switch
