Atlas provides great service and installation - start to finish. We had to replace our AC unit - it was 25 years old and a total energy hog. I asked Atlas, who does our regular furnace maintenance, to provide a quote for a new unit. They sent Matthew out to the house, we inspected the job - took some measurements - and he provided some options at various price and efficiency levels. The whole conversation was terrific. Great explanations, weighing the options and pluses of each unit. Totally no pressure - just a great commitment to get it right. We finally settled on a plan - the pricing was very competitive and arranging the installation was arranged. It went off without a hitch, the installers were very efficient, explained everything as they went, and the clean up and disposal was phenomenal - you would not even know they were there! Can't say enough about how committed this company is to service. Very rare in my experience (don't get me started on the fridge repair company which was just the worst!). and I would not hesitate to recommend them to anyone. Great service start to finish and Matthew is the best sales guy I've ever dealt with!
