HVAC reviews in Philadelphia, Pennsylvania

Gen3 has done all of the major electrical work in my older home. I trust their work. Their response time is excellent, and they were able to handle all of my larger projects in a timely fashion. For my HVAC replacement, Luis Blazquez was super helpful in guiding me on my new systems.

I don't know if I've ever encountered a technician as determined as Brian. This was not an easy repair but he was persistent throughout the process and made a point of fixing parts as opposed to making me pay for a replacement. Throughout the process he was friendly and did a great job explaining what he was doing. Separately, the folks answering phones at GEN3 were great. This is the third time I've used their services and I wouldn't hesitate to call them again.

My experience with Gen3 and Pat Curran was absolutely the most professional, genuine, and utterly favorable that I ever had dealing with something as important as replacing a 74 year old heater with a new, state of the art Trane furnace.

Where to start? My daughter told me about this company with wonderful reviews, so I called to get one of their free estimates. Mr. Curran, Pat, reached out, and not only provided me with a fair stimate of the cost, but a compressive scope of work, including every detail of what I could expect to be done, from start to finish.

Neither he company nor Pat was pushy or aggressive. Rather, they waited for me to reach out with my decision, and upon acceptance, the wheels began turning consistently to provide me with the best possible service and communication throughout the process.

I simply cannot say enough great things about Gen3, the technicians at the site and Pat in particular.

By far the best.

Sincerely,
Dr. Cynthia Alease Smith

Robert and Chris from GEN3 were out today to update my electrical. After decades of a fuse box, our house now has a breaker box with 200 amp service! They are so professional, friendly, did excellent work, cleaned up meticulously and were extremely tolerant of (and amused by) our silly dog. I had the utmost trust and confidence in them and GEN3. Bonus..my son can now plug his guitar p in the basement without unplugging my dryer.

Highly recommend this thoughtful, thorough and highly competent company. Thank you!

Jordan is the best. He came by and fixed multiple issues in my home. He listened to all of my concerns and explained things in a way that I could understand and helped me prioritize what fixes were most important for safety. I’ve already recommended him to my friends.

Jerry Hines from Gen3 was very attentive, knowledgable, and professional! Jerry was able to diagnose the important electrical issue at my house and schedule a repair for the very next day! Griffin Bunn did a fantastic job! Same as Jerry, knowledgable, professional, and responsive! Came out early in the AM and performed the necessary large size exterior electrical repair with his colleague in 4F weather...for whomever lives in Philly and needs electrical repairs, GEN3 is a serious company, doing great work!

Jordan provided an excellent experience as he developed the estimate for the electrical work we wanted done. He listened to our desires and provided additional improvements to our requests. He was very knowledgeable and he has a friendly demeanor.

I've worked with Gen3 for many years now. They are exceptional because they show up when they say they will. Pricing is transparent. The communication around appointments is excellent. Every technician who has done work for us has been very professional, knowledgeable, and respectful of my home. Today we had an outlet replaced by Rob P, who was terrific. Kudos to the management team for hiring great employees/contractors and for running a tight ship.

My only gripe: Recently, I feel like they are constantly trying to upsell me on additional services and upgrades. I suspect it is built into the technicians' performance metrics to make sure they try to sell additional services to the homeowner. Perhaps they have been bought by, or are preparing to be sold to, a private equity company. Regardless, I value their services because they are dependable, punctual, and friendly.

Had an electrical service appointment done today with Gen3 and everything was checked and completed in a quick and timely manner. My electrician, Ed Callahan, was very informative and down to earth. He took the time to explain some aspects pertaining to my concerns with my outlets and breaker box. He also was honest and straight forward with pricing and didn't push to upsell me on anything, which I greatly appreciate.

His knowledge and expertise is top-tier.

10/10 will request Ed again if I am ever in need of future electrical work.

So I'm pretty late to the game because this work was done almost 2 months ago, but I just wanted to say Will did a good job Fixing my light in the garage and adding the extra plug so I have one in my garage because I did not have one before and he was super awesome polite, professional And got the job done.

Part 2: recently, Jeff came by to give me a quote on a mini split that I hope to do in the future, and he was also really awesome answered all my questions and just all around a awesome person looked into some things for me to make sure I had all of the correct and available information.

I have used this company twice now and I have not regretted it and I will continue to use them.

Also shout out to Cindy for always following up and checking and just all around being a sweet fun person in the office

I made a next day appointment for Electric Services for an electrical inspection and to replace a timer with a 120v switch, purchase and install outside lightbulbs, add a new GFCI outlet above the kitchen counter, and replace the vestibule light fixture.

Nell, the technician was prompt, respectful, thoroughly explained the work, and completed the tasks correctly and in a timely manner. He also used a mask that I supplied and his shoe covers.
The cost was somewhat high but was reduced, since I was signed up for the Gen3 monthly Home Protection plan.

Very happy with our new mini split that was installed! It's provided so much relief to my third floor office already. Eric and Luis were exceptional technicians. They were professional, knowledgeable, efficient and clean. Couldn't ask for more! Pat came to review the job initially and was very helpful in answering all my questions to put me at ease for this semi large project. I'm a repeat Gen3 customer and will continue to be!

From the initial estimate for knob & tube remediation through project completion, the level of communication was truly exceptional. The follow-up after the estimate was prompt and thorough, and I appreciated the daily messages confirming when the technicians would be arriving. The photo and introduction of the lead technician ahead of time was a thoughtful touch that made me feel comfortable knowing who would be in my home.

Everyone on the team was professional, friendly, and respectful. They cleaned up at the end of each day and took the time to walk me through what had been completed, as well as what to expect next. All of my questions were answered clearly and patiently.

The project stayed on schedule and was even completed a day earlier than expected. I truly appreciate the team’s hard work and am extremely happy with the final result. Shout out to Rob T. and Alex P. who were on-site every day. Couldn't have asked for a better team. Franklin (my pup) already misses them.

I used Gen3 for an electrification project above $50k and would recommend finding someone else. I have found that they seem to let details slip, miss manufacturer installation instructions, and may break multiple items.

The electrification project required upgrading the electrical service, adding outlets for electric appliances, and replacing a water heater and HVAC system. We initially chose Gen3 as they were listed by an equipment manufacturer as a premier installer and reviews online seemed positive.

Through the project the installation teams seemed to change frequently resulting in overlooked details. Multiple holes were left in the sides of my house that were not air sealed. A humidifier installation was "done" but it didn't work. The installer didn't seem to test it before leaving. On several visits the installers broke items and did not mention it until I found the damage later on.

The installers were always nice and wanted to do a great job. With the frequent changing of technicians though details were lost on every switch. Communications through the company, specifically regarding project management, may be the issue. I found out that staff turnover at the company complicated the project.

Some of the equipment seems to work fine but I spent the summer with an AC system that couldn't cool my house sufficiently. The service tech said this system was more complicated than they usually install. Twice in 6 months there were refrigerant leaks requiring days to find and seal. It seems to be they installed a system so complex that they couldn't figure out how to get everything working well. I'm looking now at other contractors to fix these issues.

Update 10/29/2025 -------------

Debbie from Gen3 reached out after my initial review looking for more information about my experience. She was looking to have a manager come out with an equipment expert to diagnose my problems. After 2 months with no manager or equipment expert coming out she said my installation was unique and it was hard to get someone out to work on it. This is a system that Gen3 installed. The Gen3 salesperson at the time worked with an equipment expert on the configuration.

Debbie recommended another company come out to service my system. Inspection by another company pointed out a code issue and a few installation concerns. I'm having much of the work from Gen3 removed and replaced by another company.

Gen3 was great from start to finish. I cannot say enough good things about Pat Curran who came out to do the estimate for our mini split install. He was professional, kind, patient, and did not try to upsell us on anything - he offered different sizes and models/brands making sure we were comfortable with our selection. Other companies only gave us 1 option (the most expensive brand). Pat’s the reason we chose Gen3. We ended up needing to upgrade our electric, so we worked with both the HVAC and electrical teams at Gen3. Evan, Griffin, and Luis were terrific. Cindy and Andrea in the office were also very nice. Andrea scheduled a few phone calls with us to make sure we got the best possible price for this large project. Many other companies we reached out to were unsure how to deal with the layout of a Philly row home, particularly for the electric wiring, but Gen3 found a way! During the install, Luis (HVAC) and Griffin (electric) checked in with us throughout the day to make sure we were happy with placement and overall processes. I’m very happy with how everything turned out. House projects are always daunting but Gen3 made it as easy as possible!

Got a new unit installed and from start to finish, HVAC Central was very responsive and answered any questions I had. It was fast but the line of work is very detailed. Would recommend.

Fast, yet meticulous and experienced.

We called HVAC Central to upgrade our old unit to a high energy efficient one. On installation day, they arrived on the estimated time window, prepped and ready to start within minutes.

After installation, they walked me through all the functionality and upgrades, and even showed me how to change the filter when it comes time. Everything was put back to where it was and cleaned up. It was as if they weren’t even there, and a new unit just magically appeared after a few hours. Absolutely recommend!

I will be sure to tell everyone I know who to use as a heating and air-conditioning company. AJM HVAC BEST IN TOWN. I am so proud of this company. I am so blessed to have them service my heater, and with the level of professionalism cannot be matched. Check.

I wouldn't recommend that company

Great service, good people.

Good Quick Service-
Got the Parts & Job done Quickly.
Thanks!
