We asked Westisle for a quote to replace our 23 year-old heat pump. They recommended a Mitsubishi variable speed 2 1/2 ton unit. The quote was reasonable and competitive. Installation was done in three days at the time promised. Bristol, the installation technician did a neat and tidy job and we are delighted with the results. The Mitsubishi unit is much more comfortable than the old unit was, providing a very steady room temperature with no cold drafts at start-up or shutdown.
