This was the BEST EXPERIENCE we've ever had WITH ANY CONTRACTOR of any type, EVER. I would recommend them to anyone for any of the services they offer. Initially, I chose Jack Lehr due to their response to a previous review. The fact that the president of the company would take the time to respond to the review meant he cares about the reputation of his company and the satisfaction of his customers. His assertion that they charge by the job and not by the hours spent at a site, and that they follow through with the job until it is completed to the reasonable satisfaction of the customer, demonstrated ethical business practices and integrity. From the moment I placed the call to request an evaluation of our furnace, I felt confident in my decision to employ Jack Lehr Heating Cooling & Electric. The receptionist was genial, polite, and accommodating. Other companies have implied that loyal or repeat customers receive better or more immediate service. Jack Lehr seemed to value my business with the same quick attention and excellent service that a loyal, repeat customer might otherwise receive. We called in the midst of sub-zero temperatures and with several feet of snow accumulated on the property. I imagine a heating company was rather busy amid such conditions, but we were able to get same-day service, and sub-sequent emergency installation of the requisite replacement furnace. We had 3 different service appointments and 1 sales appointment with Jack Lehr technicians, and every employee arrived immediately when they stated they would. The service appointments were quoted as beginning between 0730am and 0800am, and technicians arrived at 0730 on the dot. The salesman (for the replacement furnace) promised to arrive by 1430, and so he did. Extreme care was taken to protect our surfaces and furnishings, including boot covers and drop-cloths. I shamefully admit our basement is messy, and I think it was actually cleaner when the gentlemen left than when they arrived. Initial technician diagnosed malodor as result of cracked heat exchanger, resulting in dangerous Carbon Monoxide levels throughout the house. Thank goodness they perform Carbon Monoxide testing, as not all companies are equipped/certified to do so. I was instructed to open windows to vent the house, and he was forced to disable the furnace. He informed me that the heat exchanger was broken and that the furnace would require either a new heat exchanger or a replacement of the entire appliance. He stated that their salesman was available to speak to me regarding my options, and fortunately he could arrive within the hour. The salesman was wonderful. He was a former technician, thus he had the technical expertise to accompany his complete familiarity with the high quality products they carried. I was provided with several options at various price points, and additional a la carte upgrades were also offered. Moreover, he offered to remove the pesky, unused humidifier - a legacy from the previous homeowner - gratis. He left for about an hour to draw up contracts, and I was given time to do a little internet research on the products he had offered. When he returned, I felt confident in my decision to purchase certain products and refuse others which we couldn't immediately fit into our budget. I was especially happy to have modern, energy-efficient options, to which we did choose to upgrade. We were also loaned some space heaters to keep the house safe and comfortable until the new furnace could be installed. - a huge relief, as the temperature reached -1 that night! All employees whom we met were very friendly, seemed extremely knowledgeable and competent, and demonstrated high integrity. They all seemed to like their jobs and sincerely care about the quality of their work and the customers' comfort and satisfaction. The technicians took the time to completely review the work with me, even taking the time to show me the cracked heat exchanger. Numerous complimentary upgrades were thoughtfully included in the service, much to my delight: replacement of the original water hose (which was dirty and moldy, but still functional) and a complete replacement of the old exhaust pipe (an unattractive pipe, which was replaced by a modern, attractive combination exhaust/air-intake system). The gentleman who installed it had to repeatedly traipse through several feet of solid snow-pack, for which we are completely grateful and humbled. We are completely satisfied with the new furnace. It is quiet, efficient, and warm. The old furnace only heated the air to 90 degrees. If I remember correctly, the technician tested this one at 120 degrees. The humidifier was quickly removed and the area patched beautifully. Jack Lehr Heating Cooling & Electric will forever have our endorsement and gratitude.
