Installers, Damon and Josh, were on time, courteous, and very professional. They tested everything numerous times to make sure everything was working correctly. I will recommend Holland Heating and Cooling, Inc. to everyone. I would also like to mention their Service employee, Jim ? and Sales employee, Chuck Hilscher, both very professional and informative. The price was very reasonable and the quality of their work was great. It has been a pleasure doing business with Holland.
