"Initially, working with Universe went very well when we replaced a central air unit and installed a single-head and triple-head ductless unit... for about 1 season. After that, numerous issues arose (under warranty) from full line-replacement on the ductless units to having to come back to repair a wired connection that was reversed. This caused the AC to not work and have lots of moisture leak through our units. Additionally, pretty much EVERY season we have had an issue with our "brand new efficient systems" not working or failing. We leveraged the warranty and figured all the "kinks" of the installation were worked out over the first few years. Now, with the warranty expired for a year, we have had to have them back to our house several times with a service charge with absolutely zero consideration for the large project we have done with them and our dedicated customer history. We paid for those, thinking we would be done with repairs, as the tech said... Two days ago, with one single-head unit not powering up, they wanted to charge $285 just to show up to take a look at the issue... couldn't even send someone over when convenient to take a quick look... Severely disappointed in this "family business" that treats loyal/dedicated customers as a number. Their installation of ductless systems seems mediocre at best."

When you need help with your heating, ventilation and air conditioning, you don’t want to hear that your technician is stuck in traffic. You won’t hear that excuse from us. We’re based in Brooklyn, at Sheepshead Bay road - in an office, not a phone drop or a postal address. It gives us quick access to many of our customers. But we also have workstations in Staten Island and Long Island. This way, our techs can quickly help you, whether you have an emergency or a routine call. They can rapidly fan out across Manhattan, Queens, Brooklyn and Long Island, ready to install mini-splits and portable AC units, clean chimneys, service residential and commercial HVAC systems, solve your radiant heat problem or get your furnace running more effectively. Our techs are experienced in all sorts of HVAC installation and repair, from heat pump systems and oil furnaces to air conditioner compressors and ac units. How we began As veterans of the industry for more than 10 years, we formed the company in Brooklyn in June 2016 with just one van and one technician. Fortunately, satisfied customers have rewarded us with many referrals and now we have seven vans and 15 people on our team, including office staff. We’re very proud and very grateful for our success. The team leader is Greg. He oversees all three locations and keeps us organized, making sure we respond to calls and we don’t leave until the customer is satisfied. Our techs are experienced, licensed and insured. We can help you, whether you want a new heat pump, a boiler repair, clean air ducts or a commercial HVAC overhaul.

"I called Premier HVAC Services for a routine check-up, and they never showed up. After waiting 3 hours, they rescheduled for a week later without any apologies. Completely unprofessional and unreliable. I wouldn’t trust them with my HVAC needs."

"NYC Sewers helped us do hydro-excavation around utility lines in a new development project we did. We also hired them to clean and later maintain dry wells in our strip center that were flooding with heavy rains. Each time they were professional and knowledgeable and their prices were great compared to other companies we contacted."

Install Boiler questions, answered by experts

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Fixing a radiator is worth it because it costs less than fully replacing it. Sometimes, a little troubleshooting can go a long way. The issue could be as simple as a blown fuse, a malfunctioning thermostat, or a loose valve. Plus, your daily life wouldn’t be too comfortable without a functioning radiator.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
