Description of Work: An air conditioner that I had purchased only 7 years earlier from Bob Hamilton failed this summer, which I found quite disappointing. Nonetheless, I decided to purchase a new one when the cost of repairing a compressor leak seemed quite high, and I had out of town company arriving that week and the house was 85-90 degrees inside so I needed a quick solution. When I met with the salesman, he assured me there would be no problems servicing the new Ruud I selected. The installation seemed to go well and they were very polite and cleaned up, etc., but they could not install the thermostat that was to go with my system because my wiring was not compatible with it (which I found out after the HVAC had already been installed.) The installer said he would return the next day with the new thermostat which would be a higher-end model. I waited at home that Friday afternoon but heard nothing and no one showed up. I called Monday and was told the part had not come in yet. It took multiple phone calls, each initiated by me, to nail them down on when someone would show up to install the thermostat. I felt that the office did not understand the difficulties in missing work to try to be home to meet a repairman without enough notice about when they might/might not come. Finally, the thermostat was installed and the system seemed to be working fine--but only for just a couple of days. The A/C failed over that weekend, seemingly related to the new thermostat. The saleman who had sold me the unit had told me to call him directly if there were any after hours problems, and not deal with the office, which I thought was odd, but I did so. The technician that came to my home that Sunday afternoon was very polite and tried hard, but he lacked the expertise and experience to correct the problem-- even after installing a simpler, more straightforward thermostat at my request when it had become clear he could not fix the more complicated one. I gathered he was very new on the job. He even called the more expert technician over the phone to get guidance, but, in the end, he could not fix it. After communicating with the dispatcher and other technicians, it seemed that no one else was willing to come try to repair it on that Sunday afternoon. I was told the best they could do was send someone else the following day. By evening, my house was nearly 90 degrees, with out of town company that had to be taken elsewhere to sleep. I was very disappointed that Bob Hamilton was willing to sell me a pricey and supposedly highly reliable brand, but not willing to service it to get it working within just days of cashing my check. The following morning (a regular working weeday), a more qualified technician came and identified the problem very quickly and fixed it. He also was polite and helpful. When I indicated that I was angry enough to plan to subsequently seek A/C repair service from a different company that would be more responsive and send appropriately experienced after-hours technicians, he warned me that Bob Hamilton would not honor the 10 year parts and labor warranty that I had been promised, if I were to get it serviced by any other company. No one had told me this at the time of the purchase. The high pressure salesman had only told me that the warranty required that I have the annual fall and spring routine service check, but nothing was said about any other limitations to a warranty that I thought sounded quite appealing at the time of purchase. In summary, the inidividual technicians were polite and professional in their interactions, but the company as a whole has let me down. I have had one A/C fail in 7 years, a furnace fail in 5 years, and now this recent problem with no one being willing to step up on a Sunday afternoon to effectively service a brand new purchase that cost me $8000. Now, I feel trapped because of the warranty issue and plan to discuss it directly with Bob Hamilton to complain. Finally, I would comment that on the morning the first salesman arrived and promoted the Ruud A/C, a second salesman showed up just after the first one had left. I think that, overall, something seems awry within the company on the HVAC issues in terms of internal communications, relationship among salespersons, coordination between the dispatchers and technicians regarding customer's needs to know when to expect the technician, and then lack of adequately experienced technicians to make repair calls. I have stuck with Bob Hamilton for the last 16 years since moving into this home, and for plumbing, have no particular concerns other than the prices seem on the high side. So my comments here are specific to HVAC sales/service.
