My heat pump started blowing cool a few days ago. After another company came out and estimated it would take $2000 to repair my system (and recommended that I buy another one) I called Wolff for a second opinion. I was referred to them by one of my family members.
One of their guys came out today and spent quite a bit of time on my roof before coming down and telling me what the problem was. He said that aside from being an old system, the only thing wrong with it was that it was 4 pounds low on refrigerant. This was a stark contrast from the first company that came out, who said that I was out of refrigerant, there was a refrigerant leak needed to be fixed, and two other pieces were broken.
When I heard that the only issue was being low on refrigerant (and that the price they quoted me per pound was $30 cheaper) I was very relieved. The tech filled it up within 15 minutes and my house was warm again.
I'm really glad I called Wolff for a second opinion, and that I didn't get grifted (as it seemed the other company was certainly trying to do). I'll certainly be calling Wolff again in the future when things go wrong and recommend them to my friends and family as well.
