Don't ! I was a loyal customer, but when something went wrong, the company addressed the situation poorly and unfairly. In the past, I received excellent service from their customer service representatives on the phone and with the technician (Don) that performed work at my house several times. But, the response (or lack of it) from their managers lost my business for good. <br /> Through all my interactions with them, I was calm and polite. Here's a summary of what happened: I arrived at my house early one evening and the furnace was not functioning. Temperatures outside were sub-zero, and it was barely above freezing in my house. I immediately called Spengler, and the customer service representative said she would have someone come out as soon as possible, but it may be several hours. The technician, who I had not met before, arrived as promised and tried to diagnose the problem and repair the furnace in the basement. During this process, he caused the thermostat upstairs to catch on fire. Luckily we discovered what happened before too much damage had been done. The fire destroyed the thermostat and charred the wall. It also filled the house with acrid smoke (think burning plastic), and I had to open the windows and doors to the cold to air house. I think the technician was as shocked about it as I was because he quickly wrote up an order identifying a bad control board and a bad thermostat (!) as the problem, and he tried to upsell me a $3200 service plan while standing in my hazy freezing house. He said he would get the parts ordered, and the furnace would be repaired as soon as possible. <br /> Obviously a mistake was made. When I called Spengler early the next morning about what had occurred, the customer service representative was helpful, as usual, and said the service manager would call me soon. My credit card was charged $500 for the new part. By that afternoon, she appeared to be as frustrated as I was that the service manager hadn't contacted me. When he <br /> finally contacted me, he was arrogant and rude. When I told him I already had the situation inspected by several professionals, he <br /> agreed to repair the wall, replace the thermostat and have his senior technician come out and install the new part at no additional charge to me. The senior technician did arrive later that afternoon, and he declared the furnace unsafe and beyond repair. He could not determine what damage had existed beforehand and what damage the previous technician may have caused. The new part was useless. He contacted the service manager and told him so, and he implored the manager to give me a break on a new system. We agreed that the $500 I was charged would be applied toward the new system. At this point, I'm still trusting Spengler. <br /> <br /> The sales guy arrived that evening and quoted a price of $10,713.65...that was giving me a break and applying all applicable discounts. The sales guy showed me all of this on a tablet, and I had to write down all the information myself. The next day, I got bids for comparable or better equipment from other companies that were $5350, $5632, $7522, and $7862. I called Spengler, told them I was not purchasing a system from them and to please refund my $500. The service manager contacted me and flat out refused to do so. <br /> My wall was repaired over the next several days. I sent a letter asking for the refund. Over the next several weeks, I was told the customer service manager would contact me, but he never did and he never returned my calls (the customer service manager!). The operations manager called once and left a message saying if I wanted to discuss the situation I had to call him back in the next 10 minutes. I contacted my credit card company, and they immediately initiated a charge back to refund my $500 and said a penalty would also be issued to Spengler. That was the last I heard from them.... until a month later when I received one of those automated "Thank You" cards in the mail, with a picture of the technician who caught the thermostat on fire, thanking me for my business. The reviews mentioning high pressure sales tactics and overpricing happened in my case, too. The arrogant and awful management was also exposed. I never received an explanation or apology, only grief. <br />
