Our heating and cooling system entirely needed to be replaced; We’d been researching the whole Heating and A/C thing for quite awhile and finally selected the company to do the task. They were great about giving us literature about what to expect before, during, and after the upgrade. First they commanded that my friend and I transfer anything away from the section where the work would be done. They had limited liability regarding homeowners’ possessions being harmd by the installers… And they knew that my friend and I have a cat, so they recommended that my friend and I keep him away from the workers during the process. They provided us the names and background of the three women that would be doing the upgrade, stating that all of their work would be warrantied. Of course the old system had to be detached first, so they would need access to all of the areas of the home where the Heating and A/C device was housed; My friend and I were told to expect additional time if the existing ductwork needed service and/or replacement, and that one or two of the workers would begin that process while the lead installer would be assembling the Heating and A/C equipment. The workers would install components such as the thermostat, drain lines, evaporator, compressors, and on and on the list went. The literature noted that there was regularly a chance of unforeseen circumstances, such as replacing rotten wall studs or drywall repairs. Finally, pressure and vacuum tests would be performed, along with many other mandated testing. At the completion of the upgrade, my friend and I should expect the companys to go over the complete operation of the system with us. At that point, my friend and I could prefer the benefits of a comfortable home for many years to come.
