We are very happy with the service we receive in relationship to the technicians. They are always courteous, respectful, knowledgeable, and thorough in when they service our home. However, we are not pleased with the increases in the cost of our services over the past 3 years. Rates are increased without our knowledge (or the technician's). We understand that related prices, such as gas, increase. That being said, our rates do not decrease when gas prices go down, as they have recently. If our rates are increased on a regular basis, we would like assurance that the people who make your business successful (your technicians), are also rewarded through these significant hikes in our bills.
