HVAC reviews in Colonia, New Jersey

The reviewer is very satisfied with the service they received.

Here's a rewritten version of the customer review:

We had issues with our air conditioning last September, which led us to contact Nowak Air Systems Inc. after getting a referral from a local contractor acquaintance. Mark showed up and fixed the problem, but since the system was nearly two decades old, he wasn't sure if it would make it through another season. We asked for quotes on replacing both the HVAC system and water heater, which ultimately prompted us to hire them. Despite some uncertainty about the age of our equipment, we're extremely satisfied with Mark and his team's professionalism and attention to detail. Their services are highly recommended, and we'll definitely reach out to them again when needed.

Great work done.

"Job well done."

He's very professional with fair prices and courteous service - I highly recommend him to anyone seeking top-notch work.

SOS saved us from a scorching hot apartment, literally. They were able to schedule a repair on short notice and Sergio showed up on time. He diagnosed the issue as a capacitor problem and had the necessary parts in his truck. Beyond the fix, Sergio offered practical advice on maintaining our aircon unit.

I'll definitely be reaching out to them for future tune-ups and repairs. Their professionalism and expertise earned my trust, and I appreciate their timely intervention during this sweltering week.

The technician from SOS tech did a thorough annual check on our old furnace and found it needed replacing due to a cracked heat exchanger. The unit was over 30 years old, so it's no surprise. They gave us some options with varying price points, which helped us make a decision. A new furnace and air were installed in just one day by their skilled team - we're extremely satisfied.

We've worked with Sergio for a few years and he's consistently reliable, addressing our HVAC concerns promptly whenever they arise. He's also thoughtful of our family situation with a young child, often prioritizing speedy solutions that suit our needs. A trustworthy professional with reasonable rates - we'd definitely recommend him.

Sergio is a trustworthy, expert technician who consistently delivers high-quality work. He thoroughly explains each step of the process and addresses all your concerns. His professionalism, courtesy, and attention to detail make him stand out - I wholeheartedly endorse his services.

He's always reliable, knows his stuff, and keeps you in the loop. Gets the job done to a high standard - no complaints here.

Sergio has helped me a few times already. First time was during a heat wave and my AC stopped working. He knew right away that it was a bad capacitor and happen to have one on his van. Second time was when my old Utica boiler stopped working and I ordered a new valve online. I couldn't get it to work so I gave him a call, he quickly came over and he found out the valve I bought just wasn't working... again, he had the correct part on his van and got my boiler running again.

I highly recommend Sergio (SOS Heating & Air Conditioning).

Sergio is the best in the business. He's helped us with so many different issues and needs throughout the years. His team installed a brand new boiler and heating system in my house and it works perfectly. We have a small child at home so it's important we maintain our systems properly and I can always rely on him to help us. I would highly recommend him for your heating and air conditioning.

Sergio installed central air in both of my houses. He did a great job! He maintains and does all repairs whether it's heating or air conditioning. He stands by his work.
