Couldn't have been better unless it were free :-) Dave Hepner, the salesman, came by on Monday to give us a quote on the same day I called the office. He came later on in the day despite having worked all day in Fuquay (I'm in Durham) and clearly suffering from an injury he had sustained earlier in the week. He was personable, honest, knowledgable and no salesman-esque BS. I appreciated that he came at all so late in the day but when he gave me the quote and explained everything that it would cover I was stunned to see it came in $2,200 and $1,200 lower than the two previous estimates I had had done earlier that day. Sold! The work was scheduled for Wednesday, quick turnaround! The first team Richard and Adolpho (apologies if I butcher names or their spellings) arrived about 9:00 am as promised, and introduced themselves. They explained the process and what to expect, asked for access to the necessary areas of the house, and in return I begged for them to tread softly on my new grass planted in the installation area. They began to break down the old system and I returned to my work. An hour or so later the second team Brandon S. and Chuckie arrived and started work up in the attic removing the heat exchanger, flushing the refrigerant lines, and sealing the duct seams with goo. It turns out, one of the air handling manifolds was sub-standard and Brandon took it upon himself to replace it at no additional charge! They also cleaned out a return manifold for good measure, and I didn't even know I *HAD* a return manifold. Chuckie installed 2 carbon monoxide alarms that weren't even on the estimate, more freebies. Finally, they explained how I should maintain the HEPA air filtration system since I am new to this house and was unaware of how to do so. I went outside to check on their progress at around 3:00 pm and they were nearly finished; I was startled to see the new units operating already. They were were attentive, polite, professional, and light-hearted despite my clumsy request they take my junk lawnmower along with the hulking old HVAC units. Richard was all too happy to comply. The mower still works too, I hope he gets good use from it. Finally, Brandon walked me around the house and pointed out everything they had done and asked if there was anything else they could do before they finished. It took them another hour to button up the job, clean and police the area. They even trimmed around the units with fresh mulch. And just so you know, my new grass survived the ordeal and still looks great.
