We have used this company for many years and have been so pleased with the level of service.  We bought a water cooled unit that is difficult to get parts for and needs a lot of TLC.  Paul and his crew always find a way to keep us up and running.  We have an ongoing maintenance agreement with them and they are great about reminding us twice a year to make an appointment to have heating/cooling inspected.  Service is great and prices are fair.  Nice to have a company we can trust.
