I initially chose EM Energy & Air bc I liked the straight-forward approach that the owner, Eilon, took when meeting with us for our free consultation for our HVAC installation. I also liked that he had all 5 stars on Yelp.
However, now that the job is complete, I have multiple concerns I'd like to warn future clients about.
Pros -
Eilon, the owner, is responsive and he seems to know what he's doing. Defensive of his company.
Cons -
When the job was "complete" by other people in the company, we noticed extremely low air flow from our vents. Eilon did not come by for a final check or run-through to inspect their work until we provided unsatisfactory statistics (it took 2 hours to heat our home 1 degree) and asked him to. After he came, an additional $2000-$3000 scope of work needed to be done for the HVAC system to fully work, which had we known initially, we would have chosen a different vendor.
After the additional work was done, an inspector came by so we could get the work permitted. The inspector said, and I quote, that the job reeked of "poor workmanship." Mind you, I don't know anything about HVAC installations - I just trusted Eilon to do the job well - so as you can imagine, I was livid that we paid over $20K for "poor workmanship."
Obviously, the job did not pass inspection. We did not get the permit. There were multiple areas that needed to be improved or fixed before we could get a permit. Of the 6 areas the inspector pointed out to me that were done poorly, some included major safety concerns like the gas line not being capped. This is a major safety hazard as children/pets/people could accidentally knock into or turn the gas knob. See photo.
Another area the inspector raised as a concern was that an old vent pipe needed to be removed and the ceiling sealed. The inspector said that the current setup woud allow for rats, bugs, and birds to come through. He also labeled this "poor workmanship." When we brought this up with Eilon, he responded with, and I quote, "outside of the scope of work in my opinion but we will do them anyways."
Excuse me, "outside of the scope of your work" but yet it is required to get a permit for the work you did?! And wow, "we will do them anyways" is just terrific customer service (do you hear the sarcasm in my voice?).
It took another round of fixes and another round of inspections until it ultimately passed. Which is why I'm giving my review 2 stars and not 1 star.
Summary:
If you understand the world of HVAC installations, have a lot of spare money/time/energy, and can advocate for yourself, go with EM Energy & Air. If you, like me, know little to nothing about HVAC's and care about spending your money/time/energy wisely, I recommend you go elsewhere.

We used EM to add insulation in our attic and crawlspace, to replace our ductwork, and to install attic stairs. They were easy to work with, the price was good, they did the work as they promised. The only thing that wasn't ideal is that I paid them extra to pain the ceiling and the new attic door. They brought in another guy to do that and the quality was not great. However, when I spoke with Eilon about it, he refunded the amount I paid and I just did the work myself.

I had started doing some remodel work and crawled into the attic to install some canless lights. I was met with an area covered in rat feces and urine. Additionally the insulation looked extremely old and in some parts was scattered haphazardly around. I decided it was time to get it done right and quickly knowing what was sitting above me while I slept. I reached out to a number of companies on Yelp to get some quotes and their expert opinions.
Eilon responded to my request for quote within a few hours and arrived exactly on time a few days later. He masked up and did an extremely thorough inspection on both sides of my attic, identifying issues that other companies missed such as holes in the exhaust on one of my bathroom vents and more importantly that one of my HVAC runs terminated nowhere and we had been pumping delicious heat/AC into the attic the last 3 years.
After he was done with his inspection, Eilon sat down with me and went through all the problems he identified with pictures to back it up. He then went through the quote process pen-to-paper (literally) and gave me different price points depending on the type and R value of insulation. Additionally he broke down the cost of fixing the other items he identified.
What I appreciated the most from him is there was never any sales pressure - he presented his findings, the cost with options, and answered my questions without any tone of FUD.
I decided to go with EM Energy&Air after getting 4 other quotes -- his pricing was very competitive with the others for approximately 800 sq ft. His team was able to come out the very next day.
Elmer arrived with his team a little before 9:30AM. We first walked the house so I could show them the accesses and decided the best way to run their equipment. The 3 of them then spent almost 30 minutes taping down plastic and soft materials around the house as to not cause any damage and prevent materials from circulating while they did their work. The crew worked nonstop for almost 6 hours, taking out all the old insulation and other materials (including some large rolled up carpet that was thrown up there -_- which they offered to dispose for us), sanitizing the space, rodent proofing, sealing holes/cracks between the house and attic, and blowing the new insulation in. This is back breaking and I fully appreciate the work they did for us. After they finished Elmer showed me pictures of the before and after, specifically showing me points of entry and how they closed it up, and then asked me to take a walk through the house to make sure there wasn't any damage. The crew cleaned up quickly while this was happening and were gone by 2:30.
This was a great experience from beginning to end and I would highly recommend EM Energy&Air.
