"We have 2 heat pumps which we have serviced every 2 years. I was going to call the company that had installed our heat pumps until a friend told me that Daveâ s Mechanical Maintenance had installed his heat pump and had done a great job. I called Daveâ s and scheduled an appointment for service. Dave Curtis came to our house on the day scheduled and he arrived on time. He was very efficient and cleaned and service both units. One unit had not been functioning at full efficiency but Dave diagnosed and fixed the issue in no time. I highly recommend, if you need service or need a new heat pump installed, calling Daveâ s Mechanical Maintenance. They are efficient, friendly and provide exceptional customer service at a very reasonable price."
