When we were looking to replace our old oil furnace with a heat pump, we checked Angie's List. Our finalists were two Super Service winners, and Washington Energy Services, which was offering a strong discount. We don?t buy on price alone; in fact, we had had a good experience with one of the others, but still decided to follow the rule of getting at least three bids. We went with Washington Energy Services. The salesman for the company which we?d used before was late, having gone to the wrong address. Happens to us all?problem is, after that, we had to keep calling and writing him and his manager to get responses. Finally, after receiving a hastily put together bid, we dropped them?we?re spending over $10k, and we have to wait a week between responses? The other Super Service winner was good, very professional, but when their electrical contractor made his bid, it was over what we had been told. He was adding capacity for an extra heating strip, which we didn?t need, and a whole house surge protector, another extra. The salesman eliminated the extras, but it left a bad taste. Enter Washington Energy Services and J.J.Stefani. Right away, there was an amazing difference. I?d often get a call back within hours, or even on a weekend. He was very thorough in his presentation, explaining why a certain product was best for us, not just trying to sell the most expensive one. We signed up with them. Which is not to say that everything went perfectly. Some ducts had to be recleaned, and there was an issue with the noise of the system. At first, they readjusted the system--the next day--but it was still loud. They decided the old ducts were too small, and JJ took responsibility for underestimating the load. We worked out a deal where we got a new ducting and an enlarged air return at cost. It?s important to note that the salesman from the first company had said we needed larger ducts, but we never heard anything more about it again their communications, or in the bid. The second company, like Washington Energy Services, had thought a new air return would be enough. So we would have had the same problem with the Super Service award winners, and would have had to pay for ducting anyway; the difference here is how J.J. was communicating with us and making sure we were satisfied. It?s been almost a year now, and we?re very happy with the system. The oil heat was running about $225/mo in the winter, averaging $135/mo over the year. Our two-month electric bill for January to March, which coincided with the installation?and remember, 2012 had a record cold March?was $175. That was our entire electric bill, not just the heating. So pay attention to ducting if you?re updating from an old oil system?heat pumps blow more air at a higher pressure. Also, in Seattle, check out Community Power Works?they?re having a great energy incentives, including for switching from oil to heat pump. Unfortunately we just missed that one, but it would have easily paid for the ducting. Normally, I would reserve the 5 star rating for everything going right the first time, or nearly so, with no need for multiple adjustments. Putting a new system into an old house can be complex, and as far as I can tell, the two Super Service winners would have had the same problems, so I'm giving Washington Energy Services the top rating. I will say this?J. J. Stefani?s service is definitely 5 star?relentlessly accountable and responsive.
