Allied delivers quality through training and experience. Our commitment to training runs through all parts of the organization and it allows us to reliably deliver the latest technological advancements to our customers.

Backed by over 100 years of collective experience, the company was formed with a singular commitment to provide our customers with high quality, cost effective, on-time construction services.

A few reviews for this pro...


We used ALLIED since we purchase our home over 3 years ago because their information was on our HVAC system. On our first call we wanted to take a look at the system and make sure everything was up to par and let us know if anything needed attention. Allied sent us John Martin and he took the time not only to explain what kind of HVAC system we have but also to show me how it all worked. From the ...

The original install went fairly well. The system did in fact save me money on my bills. Where they truly went wrong is with the service aspect. You must work really **** ** your end to get them out to fix a problem under Warranty. I have not had working heat for a month and a half during winter time. The most recent tech visit, was a no show and never called. This company clearly only cares about...

Allied completed the work on my house in Jan. 2020. I was pleased with the work they had done. I awoke to the sound of gushing water around 11:15 p.m. Water was coming from the shark bite value, which connects the water heater to the water source. The water heater is in the laundry closet outside my bedroom. There was water everywhere: in the laundry room, seeping under the hardwood floor in the h...

Description of Work
Allied was listed on the South Jersey Gas website as a company that does energy audits. I bought a home in summer of 2019 and wanted to lower my utility bills. They completed an audit, sealed my attic, and add more insulation. They also installed a high efficiency hot water heater.

We purchased a “fixer-upper” and gutted it to the studs. We’ve been trying to do at least some of the work ourselves, so it’s been a crazy process. Allied’s scope-of-work with us included the following: (1) the insulation of the entire house; (2) the installation of a ductless Mitsubishi mini-split heat-pump system that included two outdoor condensers (a 2-1/2 ton and a 3 ton) and seven indoor wal...

I had a good experience. They're very professional, arrive on time, they did what they promised and they come back promptly to fix any difficulties.

Description of Work
They put in two new furnaces, two air conditioners, attic insulation, and a water heater.

The whole process was great until after the install was done and we realized there were two issues that needed to be addressed. We had to chase after the company (multiple emails and phone calls to many different people) to get them to come correct the first issue, which again was done well (the people who do the actual work are professional, courteous and skilled). After fixing the first issue, the electrician said they'd have to come back and re-lay the insulation. We waited a week, didn't hear from them. Sent an email after a week, no reply. We are now going on 2.5 weeks, after the electrician said they would contact us in a few days, without even an acknowledgement to our email. We understand completely if they are busy and can't do the work yet, but at least acknowledge that you know there is still work to be done. That's all we expect, and maybe without us having to call and email them multiple times to get even the slightest response. They had no issue sending us multiple emails and calling us prior to the work being done, but be aware that if you have any type of issue after the onus will be on you to chase them down to get it fixed. In the meantime, we have received several emails from them asking us to recommend them and to also schedule follow up service visits for our heating system (which they didn't install) but no acknowledgement that an issue still exists with their installation. It's a shame because the people who do the work are great, but with such poor followup resolution we will no longer recommend them.

We did the energy audit and had insulation and a hot water heater installed

Great. Guys did an excellent job, professional, courteous, just the best. One MINOR problem later, upper management was cooperative and the gentleman sent out to correct the issue nailed it. Exhaust pipe they added a screen to to keep critters out, was a little too restricted by silicone glue used to hold screen in place. This guy fixed it by removing the silicon and using instead a screw on the outside of the pipe. Perfect!

We are so pleased with the work done by Allied Energy Efficiency Experts. Their professionalism and expertise resulted in a great install of numerous pieces of equipment. They were respectful of our property and explained everything in detail. I would certainly recommend Allied to friends and family.

They were very extremely professional, came right on time, worked all day. Anything they moved or had to take down (shelving) they put everything back exactly the way they found it. We were extremely satisfied with the full installation. They even changed the dryer vent, re-vented our bathroom vents and added an additional carbon monoxide detector all included in the price. Would definitely use them / recommend them to others.
