On time and easy to get in touch/communicate with. We haven't had any problems with the new units and we're so glad to be rid of the oil! I would definitely use them again.

WARNING: They are out to rip you off!!! I called Adam Mechanical/Adam Home Services when my hot…read morewater heater started leaking. I am a single woman, in a panic bc water was getting all over the floor! These were their prices: $3800 for a 50 gallon tank install and $6200 for an 80 gallon tank. But then they told me that I had to get the 80 gallon bc the wiring was not long enough for the 50. And I almost said yes bc I was desperate and didn't know any better. Yesterday I had a plumber install a 50 gallon hot water heater for $2100. There was no problem with the wiring. Adam Mechanical was just trying to take advantage of me and have me pay 3 times more than I should have! And so please be warned about what kind of company this is.

Downstairs, in the basement, there appeared to have been a mini-explosion, because the heater's damper had been blown into the next room, 15 feet away. (???)! We called Boyle (after hours) and got an immediate response. In about 2 hours a technician was here. It turns out, we ran out of heating oil! And the last gasp the heater made resulted in a type of backfire, which caused that odor. Anyway, the tech put 10 gallons in the tank, and the next day we got a full delivery and a further inspection to make sure everything was okay again. We were quite taken by surprise about running out of oil. But also very pleased with Boyle's prompt response. When they got the call, they were on it. Our experiences with Boyle Energy continue to be very good.

And within 24 hours a wonderful sales person stopped a promptly provided replacement options/recommendations. We accepted their recommendations and within 3-4 days the new system was up & running.....and all this during a tremendous heat wave. To squeeze us in like that is worth more than 5 stars. Unbelievable professional & personal follow-up & communication. And we had no history with them.....we were totally new customers. Stupid other company with lack of professional approach lost a large sale. We are so glad to have found Cermignano. I never write reviews but these people deserve one. They went above & beyond for us.

He asked me to email him the other company's quote with the financials redacted, which I did. He came out on 10/14/26 and I sent him that email, and then I was complete ghosted. 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.

I looked at their website, and saw that they do duct cleaning, and the reasons for doing it. I called on July 3rd and I said I would like to hire them for the service. I gave them the square footage and and overview. They said they could see me on July 5th at 9AM. At 8:59AM a serviceman arrived. He explained what he was going to do and then went about cleaning the ducts. He said there was a moderate amount of dirt, and that he has seen worse. After he cleaned the ducts he vacuumed the unit itself, and then blew a chemical into the ducts that would kill any bacteria that happened to be there. I thought it was good precaution to take. He also showed me a better way to put the filter in the unit. I gave them 5 stars -- only because they didn't have an option for 6 stars. It's great to know there's a company like this out there.

I had scheduled my day around them coming--they didn't know the employees didn't come to work until 1215? There was no way they could have let me know sooner and respected my time? They asked if I wanted to reschedule for the next day or wait until they knew whether they'd be able to make the appointment I made. Wait, what? They're offering to give me another appointment window that they don't think they can make? Why would I ever take that option? I've decided to go with someone else. I wonder if Kanze would charge me a no-show fee if I wasn't at my house at the designated time...

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.
