We researched 3 companies, including our current provider A1 Air Conditioning & Heating, and obtained quotes to replace our ancient air conditioning unit and old furnace. In the end, we stayed with A1. Their quote fell in the middle, but their equipment warranty and ongoing maintenance package were superior, as was the professionalism and expertise shown by their senior consultant, Jeff Smith.
Yesterday, we had the our old equipment removed and new reconfigured and streamlined equipment installed ... all up and running smoothly in half a day. Before the installers left, the equipment was successfully tested and we were given a tutorial on our new toy, the Nest thermostat.
This was not a cheap home improvement project, but one that will reduce our energy costs over the years to come ... a worthwhile investment.
We recommend A1 Air Conditioning & Heating, the Daikin equipment they sell, and their maintenance package, highly to anyone considering making a change. You will receive quality products and excellent customer service.
