Very professional, polite and knowledgeable
A very pleasant experience
Tommy,Matt, and Isiah let me know they were on the way, and arrived on time. They greeted me in a friendly and professional manner and introduced themselves. They put covers on their shoes before entering the house and put drop cloths on the floors and over the furniture. Tommy went over every detail of the installation, and discussed options. They kept me informed and involved every step of the way.
The work was completed in a professional manner. They kept the work areas clean, and put everything back in its place.
This is the second large job Universe has done for us. I HIGHLY recommend this company !
Competitive pricing with the absolute best service! Extremely responsive and accommodating. Everyone super nice and easy to work with. Would give 6 stars if possible!
Detailed and knowledgeable explanation of options to repair an older AC unit versus full replacement
I’m an NYC contractor, and I don’t typically call companies like this unless I’m out of options—but I’m glad I did in this case.

I had a sink issue where the garbage disposal needed replacing and the drain kept flooding my kitchen. I actually replaced the disposal myself, but I couldn’t get the drain to stop leaking. What should’ve been a simple fix turned into a week of frustration trying to find someone reliable—nothing but excuses and half-finished work from others.

I called Universe this morning, and they had someone out by noon. Everything was completed by 2 PM.

The dispatcher was extremely professional and empathetic, and even removed the dispatcher fee after I explained that I normally wouldn’t use services like this unless I had no other option. That alone went a long way.

Jeff Madonia did the work—he was efficient, professional, and got everything done in about 2 hours. He treated me like a fellow professional, but also had that easy, down-to-earth energy like an old college roommate you haven’t seen in years.

No headaches. No babysitting the job. No back-and-forth over pricing. Just clean, straightforward work.

Honestly, for something that should’ve been simple but turned into a hassle with other contractors, this was the complete opposite experience.

10/10.

If you don’t want to deal with the stress of chasing down unreliable handymen who might have to come back three times to fix the same issue, call these guys. They give you an honest price, get it done right the first time, and back their work with a warranty.
The service guy was very professional and fixed my issue quickly with no issues.
We had substantial electrical work done by Keith and a wonderful team of Trevor and Ryan. The three worked straight for almost 9 hours, and always with a smile and receptive to answering questions. They could be heard laughing with each other, too … a true collegial team. The work was done beautifully, and clean-up was thorough. Thank you, men.
The technician was very nice made sure everything was put back correctly and neatly and he reviewed my whole system. I’d like to thank him.

Nick S. came to do the yearly service for my air conditioning. Nick is great and very up front which I like. After almost 17 years I need a new system. Ugh! He brought me outside and showed me all the reasons why it should be replaced. I could wait & see but didn’t want to risk it so Saturday I’ll be getting a new system. It just needs to be done. I was very happy Mick explained everything to me. He’s very knowledgeable & friendly.
NICK was truly professional and very friendly. Diagnosed the problem immediately. Very grateful for his service.

We get many questions throughout the day regarding household systems. Below, we’ll answer these to give you more insight into yours.

How often do you need HVAC maintenance?

We recommend AC maintenance in the spring and heater maintenance in the fall to preserve the warranty coverage on your appliances and prep them for their upcoming seasons.

Does your older home need a new panel box?

Houses built before 1980 typically have between 60 and 100 amps of power going to them. Modern homes have between 200 and 250. If you’re experiencing constantly tripping circuit breakers or flickering lights, your older home may need a panel box that accommodates more power for your devices and appliances.

Can you switch from a tank to a tankless water heater?

You certainly can. In fact, many homeowners are making the switch because tankless water heaters can provide up to 30% energy savings on the cost of heating water for your house.
