What really stood out was how detailed and honest Tom was about the work. He explained everything clearly, didn't try to upsell me on anything unnecessary, and made sure I understood exactly what was done. I believe Tom is the kind of person you can genuinely trust. I'll definitely be reaching out to him for any future HVAC needs. If you're looking for someone reliable who actually cares about doing the job right, call this company!

Bill F Terell Sheaf…read moreand Jordan recently visited our home for the second time in one week. The first time was to install a whole-house surge protector, connect a new electrical connection from the outdoor overhead electrical lines down to our meter in the basement and move the electric meter from the inside of our house to the outside front wall of our 2-story rowhouse (an additional fire protection upgrade). A week later, they returned to do some finishing safety-focused touches that were difficult to integrate into the first visit. Specifically, they: - rewired a single outlet in the living room with older wiring that was apparently missed in the 1980's when the house underwent a comprehensive electrical upgrade. The upgrade included adding AFCI circuit protection and running a new circuit from the panel - added GFCI protection and replaced faulty tandem switches in basement for washer and dryer - added GFCI protection and replaced faulty tandem switches in 2nd floor bathroom to remediate faulty functioning of heat lamp and fan - replaced existing two 3-way switches for upstairs hallway and and one in bathroom - AFCI circuit protection for the Homeline circuit panel Terell and Jordan appeared to have done an excellent job. Their teamwork, professionalism and obvious technical knowledge, experience with older houses and confidence was, like in their first visit (but moreso), obvious and appreciated. Terell in particular has a great touch with the client, exuding confidence, a great sense of humor and a desire to provide superior service to the client. He and Jordan make a great team. The two of them powered through the entire job in less than 3 hours (versus the 4 + estimated time to complete). As far as cost, the entire job, including the cost to obtain and coordinate post-job City of Philadelphia permits, came in at a very reasonable $1,000. Perhaps because we'd already sunk several times that into the first, more significant upgrade a week earlier, several items on the bill were discounted. Given the hours of highly skilled labor by the team, a couple fairly expensive equipment items and the fact that (pending City inspections) a fully modernized electrical system, I'm satisfied with the value Gen 3 provided on these two jobs. My overall experience (including a conversation with Amy about the Gen3 maintenance plan which I am definitely getting after satisfactory City inspections) was a 5+ stars. Highly recommended. Good people.

I immediately called the gas company and they came and shut off the gas line. It's the dead of the winter and now I have no heat. I didn't know where to begin. I checked the internet but nothing jumped out at me. I went on yelp and began reading reviews and I ran across Lawrence heating & air. I called spoke to a woman who was very pleasant and told me a tech could come out to assess the boiler to see if it was still usable. Joe came and he looked at it and said it it's a hazard. With all the rust and corrosion and not to mention whatever was on fire. He said it needed replacing. He talked to me about the options and stated I would get an email from the owner of my options. 30 mins later the email was there and everything was included. All the info I needed to know about the unit, specs, warranty, parts/tubing for replacement, price. It was a proposal. I reached out to Lawrence with my questions and he answered right away. I also stated my elderly dad lives with me and elderly need service as soon as possible. That was no problem. He sent me payment options as well. Once I accepted the proposal and date was locked in and they techs came the next day on time. Randy showed up first, then Joe & Chaly. They immediately put down floor draping and loaded all of the supplies , pipes , boiler, etc. They opened all the radiators starting at the top. All of them were pleasant and very Knowledgeable about their job. Any questions I asked Randy explained. They cleaned up behind themselves and made sure everything was put back in place. Once they were done Randy told me about my new unit and what was removed and put in. This company made the entire stressful event so much more easier, like a weight had been lifted. My house is warm and cozy thanks to everyone involved .. Great teamwork ! I would definitely recommend !!! Thank you so much to everyone that played a part in getting me back up in running !!

I just paid and said goodbye to Alex, and I was so impressed with him and his work that I felt…read moreobligated to write a review right away. Last year, my heat stopped working. I called several places, but Alex was the first to respond. Over the coming days, as the callbacks came in, I was told that I'd need to schedule a consultation. In contrast, Alex asked if he could stop by that day or the next. Due to a hectic schedule, I asked a friend to be at the house. Alex was very flexible to coordinate with my stand-in. While I was away, knowing I was unable to talk, Alex texted me pictures of the problem and let me know he'd return shortly (something had frozen solid, so it needed t thaw). When he was done, he texted me that the unit was not leveled properly, and it would probably become a problem in the future. I opted not to have it fixed at that time. My bad. Jump ahead to this year... The AC stopped working again this summer. I called Alex on Sunday of Memorial Day weekend, and he got right back to me, offering to come Monday (Memorial Day) morning. Again, I scheduled for a stand in, and Alex made himself available right away. He observed something simple and fixed it right away. He also did a full system check up to make sure all levels were fine and everything was working properly. A few weeks later, there was a completely different problem. It related to the system sitting off-kilter. At this point, he offered a fairly expensive fix, but he said it may work or it may be more of a band aid, as the system will need to be replaced in the coming years anyway because 1) it's run its course, and 2) the type of system will become obsolete in 2020. I was skeptical, so I called my brother who is a contractor in Central PA and has a good HVAC guy. That HVAC guy does work all over the east coast, so he'd have some sense of what's what in Philadelphia. He gave some numbers and ideas, and said that Alex was spot-on with his estimate and the info about the system being obsolete in 2020. Alex was all booked up for the week, so he offered to make the quick fix Monday morning at no cost to hold the system over until he was available the following week to replace the unit. Due to a cancelation, he was able to come today. In addition to the normal work, he had to remove a banister to get the unit to the basement, then he found some 60 gallons of water had condensed and filled some part of the unit, and then he built up an area to make sure the new unit was balanced. He did so much extra work, and then he cleaned it all up. AND THEN, because I was at work, he was able to stop by my workplace on his way home for me to pay him. Really incredible work, incredible availability, and incredible communication. And my brother's guy said he was surprised that the price was as low as it was for being in the city. I expect Alex will get too busy for all of that in the near future, but he's my go to now, and I know I can trust him. Further, he's just really nice. I have enjoyed our communication, and I'm really happy to direct business his way.

Since then he has not replied to my texts or voicemails, nor has the company replied to me when I left a voicemail at their main number. I am baffled as to why they would have this guy come out and then just completely ghost me, but after experiencing this treatment, I wouldn't hire them anyway.
