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.

"East Coast comfort did the most horrible thing to us, and they have treated us with utter contempt. We have been with East Coast Comfort since they began when Ed McCollum and Anthony Mongeluzi started the company in 2006. Both Ed and Anthony were to our home in the early years of their business, performing maintenance and repairs, and one of them was here when they installed our current unit. We gave them a favorable review on Angie’s List, and we have never had any complaints about them in almost 20 years, until Lisa Hawthorne. We schedule routing maintenance, so we do not have equipment failures and outages. We have repeatedly been asked by Ms. Hawthorne of East Coast Comfort to reschedule our maintenance appointments, and we have always acquiesced. This occurred again a few weeks ago, and we rescheduled for last week. Ms. Hawthorne again called the day before our scheduled maintenance appointment last week, asked again to change the appointment because of the volume of emergency calls they were receiving, and we agreed as long as Ms. Hawthorne promised we would be given priority scheduling if our system went down. The next day, our air conditioning failed, and I contacted Ms. Hawthorne. A technician came to our home on the afternoon of the next day, but he said parts had to be ordered, and it could be days before they would arrive. I have emails supporting that we requested Ms. Hawthorne to order the needed parts, and she emailed back that the parts would be $1500.00 and labor $500.00. Though we made it clear from our emails that we wanted to get the system repaired as quickly as possible, she did not order the parts and would not grant us priority scheduling. When we learned of this betrayal, we contacted William Henderson Heating, Cooling, Plumbing, and Electrical Services. They worked us into their schedule for same-day service. I have an email exchange that proves how disdainful Ms. Hawthorne was to longtime customers of East Coast Comfort, both of us senior citizens, and one with a cardiac condition. A request we made to Ms. Hawthorne to speak with Mr. McCollum or Mr. Mongeluzi was ignored. In other words, other people had their systems repaired because of our kindness, so we can swelter in the heat and humidity. I consider their behavior toward us to be elder abuse. Good riddance East Coast Comfort, we are now receiving our comfort from William Henderson."

"My wall gas heater one day just went out. I called several companies and was told they didn’t service that type of heater. One company gave me the number for Angi.

FAQs for heating and air conditioning service projects in Princeton, NJ
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
