We have used Kerivan Lane for years. This winter, after several oil burning problems we opted to have a third party evaluate our burner. The third party spent hours cleaning the unit and stated that in his opinion the burner had not been cleaned in years even though that was part of our agreement with Kerivan Lane. It was well worth the money and the burner was given a good bill of health.
After telling Kerivan Lane about the issue they wanted to look at it as well. They came out and immediately tried selling me a new heating system. After about an hour in the basement they ended up leaving. Later that week when I was in the basement again I noticed a very strong smell of oil that wasn't there after my third party heating guy was there.
It turns out, Kerivan Lane had spilt a large amount of oil in the basement, never mentioned it to me and made no attempt to clean it up.
After reporting this to Jack Lane, he initially denied that anyone was even at my house and then asked how I could prove that one of his men cased the spill.
That was enough for me. We have since changed and have not had any burner problems since Kerivan Lane is no longer neglecting the unit.
