New to the house, we had an annual service call 6 months prior from the company who installed the heat pump/air handler and since we didn't know anything about those systems, we got what I thought was standard. But I wasn't pleased with the performance/noise level of the units, so called WestIsle on the recommendation of a neighbour, David Shoop attended to the call and did an excellent job - took everything apart and cleaned, made adjustments, etc. Oh, and answered about 1,000 questions we threw at him during the call. Very informative. Very satisfied with the outcome and now feel like we got a proper, comprehensive annual service.
