Glenn Burkett was over to the house 2 separate times; going over options for installation and possible combination of units. Mr. Burkett provided several estimates via email. We chose the one which had a lightly used heat pump and a 'scratch and dent' furnace. The heat pump is top of the line and the furnace is next one from the top. We saw it as a good value for our situation. From the time estimate was accepted until time of installation was approximately 2 weeks. It was 2 days for install. At the end of the first day, they left the furnace functional so we could use it over night. Final cost was exactly the estimate. Approximate cost of service does not include sales tax. Installers were courteous and professional. They were at my home between 8:10 am and 8:30 am both days. There were 3 installers the first day and 2 the next day. The 2nd day of installation, it was raining outside and we wanted to limit the mud tracking inside the house. They responded positively and laid down tarps to walk on from the kitchen entrance all the way down to the utility room in the basement. That was greatly appreciated. Installers had to cut 2 holes in the ceiling of the basement closet (dry wall) to install a new 3" exhaust for the furnace and a new refrigeration line. During the initial walk downs with Glenn Burkett, he mentioned that (2) 3" lines would have to be put in. One for exhaust and one for combustion air. The installers found that only one 3" line could be installed due to limited space in the overhead. I will have to revisit the combustion line with installers to ensure our furnace is performing at highest efficiency. We plan on using Burkett HVAC again for equipment maintenance and fireplace remodel.
