E.N.Blue Ltd. last year was $220 + tax, on the agreement, there is a long list that mention what is cover and what is not include, we have their service over 10 years, they come to check and clean once a year, there was two times in the mid-night the furnace didn't work, they show up within two hours after our call. Also there was one time when they check the furnace, the motor had problem and they changed a new one for me without charge.
