3-2015:  The M.S. Johnston staff, with whom we had contact, were courteous, professional and knowledgeable.  They answered any questions that we asked and offered suggestions as to the best system for our home.  The technicians who removed our old HVAC and installed the new system worked with attention to details.  They left a clean work site at their completion of the project.

The purpose of this email is to let you know how much Myrna and I are enjoying the heat pump/ac system you provided for our home.  The system maintains comfortable temperatures throughout our home in both the heating and cooling modes.  Since the installation in February this year, the system has performed quietly and efficiently, beyond our expectations.

I would also like to commend the installation team.  You may recall there was several inches of melting snow on the ground at the time of installation.  The team was very respectful of the interior of our home and did an excellent job, both inside and outside.

Thank you for your excellent engineering and professional -installation.
