The A/C system is working well and keeping the house cool as the summer starts to heat up. Technician was knowledgeable, straightforward, and installed the unit with a great deal of care -- up to code, well-leveled etc. Why did I score them 9 and not 10? First, the scheduling was awful. I was supposed to get the unit installed on Monday. They showed up and said the work would require a pony panel (an extra circuit), which is what the estimator had told us, but that they couldn't do it and had no electrician available, so they'd come back Wednesday. They show up on Wednesday, and I get a call from the electrical sub contractor saying he can't show up because he didn't get enough notice from Reliance to do the two hour job. I tell the Reliance tech this, because for some reason their own sub didn't get in touch with them. The techs went ahead with the install (they just didn't tie it into the panel). It took the electrician til Friday to get in and do a simple tie-in (didn't actually require a sub-panel, by the way, it could be safely installed in the current 100 amp panel). The electrician was good, too, but Reliance needs to manage their subs better to reduce customers' headaches. The other reason they lost a point was because the estimator originally quoted me an obscenely overpriced amount. Like it was a bit insulting to my intelligence - 50% more than the initial quotes I got from other reputable dealers for the same equipment. The intent was obviously to sell me on renting instead of buying my unit (for $72 A MONTH FOR 7 YEARS, as if I can't do math). I called to give my regrets to the estimator and suddenly it was over a thousand cheaper to buy, which includes a five year parts and labour warranty. I know that Reliance stands behind installed products and has solid 24 hour service so I was willing to pay a couple hundred dollars more for their similar product than their competitors'. I would definitely recommend Reliance to family BUT I would make them promise that they'll get multiple quotes and haggle lest they pay way too much. (Price paid after taxes and energy rebate)
