A single dad of three kids, I was stuck at home on a freezing Saturday with my unit shut off by four seasons. They told me it was beyond repair when it's only 3 years old. But Jeremy stepped in and fixed the ignition board and cleaned the flame rod - what a lifesaver! He saved me a significant amount of money. If you're struggling like I was, trust me and recommend Northside to anyone.

These guys are total pros. They know their stuff and deliver results that meet your needs. Their focus on customer satisfaction is spot on - they're trustworthy and do the job right. It's refreshing to find a company that backs up its claims with quality work. We recently had them install our AC system and it's performing flawlessly.

Jeremy and his team replaced our old furnace, AC, and humidifier in under a day. I was impressed by their organization, efficiency, and cleanliness. They also addressed all my concerns before leaving. Their professionalism earns them my strong recommendation.

I've never used a better HVAC service provider - they're honest and trustworthy, which is a rare find. They handled both our new AC system installation and boiler work with professionalism and a competitive price. I've already recommended them to several colleagues who had great experiences too. If you need any HVAC work done, they're definitely worth contacting for a quote.

Jeremy is fantastic - a reliable professional I've been sending my clients to for over two years, with consistently positive feedback. He's definitely worth recommending.

We've had nothing but excellent service from NorthSide Mechanical, particularly Jeremy. Our condo lost heat through the boiler in the middle of winter, and after contacting three separate HVAC companies, none could identify the cause, leaving us without heat for days. We were at our wit's end, and I was on the verge of tears.

That's when I found Jeremy, who was incredibly compassionate and dedicated to helping us. He arrived the next day, and within a few hours, the issue was resolved. What impressed me most was his determination - he wouldn't give up until he found the problem. His professionalism, ease of communication, and courtesy were top-notch.

Jeremy exceeded our expectations in every way. We're now officially hooked on NorthSide Mechanical. He recently installed our new hot water heater, and it's clear that he knows his stuff. The whole experience has been nothing short of amazing - we couldn't be happier with the service we received from Jeremy.

Jeremy called before arriving, which was frustrating since I needed help ASAP. What saved the day was his expertise - he quickly diagnosed the issue and walked me through the repair process. His assistance is invaluable, especially given my kids were stuck by a space heater due to frozen pipes. It's great that Jeremy is reliable, as he also did some additional work for me in the past, which turned out well.

Jeremy and his crew did a fantastic job - top-notch service from start to finish. When my furnace developed drainage problems, they walked me through simple fixes that got the heat back on within 30 minutes. They truly exceeded expectations, providing excellent support even after the project was complete.

I've had a consistently positive experience with Northside Mechanical. They always show up on time and their staff are courteous and professional. Jeremy, the guy you speak with when you call, has 20 years of experience in both commercial and residential HVAC and it shows. He knows what he's talking about and will give you tailored advice to get your home or business running smoothly. I trust him so much that I refer everyone I know - family, friends, coworkers - without hesitation.

We switched to NorthSide Mechanical after Jeremy installed our new HVAC system, which saved us around $600 compared to our previous provider. He's done a great job, and we're extremely satisfied with the work. His prompt response times are also a big plus - he always answers the phone quickly.

Jeremy fixed my furnace issues over the phone before coming out in person to fine-tune it, which is now working perfectly. He's extremely friendly and trustworthy - I'd highly recommend him to others for his expertise and integrity.

I was looking for a local heating service that didn't involve a big chain. Northside Mechanical fit the bill perfectly. Jeremy got back to me within hours after I reached out and arranged for Steve to come by despite it being peak season. Since I wasn't an existing customer, I shouldn't have expected priority but he still managed to get me fixed up quickly. Given that, I'll definitely be having them perform a seasonal boiler inspection every fall - you should consider doing the same.

Jeremy and his team were extremely responsive, professional, and knowledgeable about their craft. We were dealing with a major problem with our boiler, which kept getting airlocked. Jeremy knew exactly what was wrong and how to fix it, offering various options for updating the system. After the initial work, however, we encountered some issues - the system still wasn't perfectly balanced despite the heating working. Jeremy and his team returned to make adjustments, ensuring a seamless solution. Given the complexity of these systems, I wouldn't hesitate to trust anyone with our boiler except NorthSide. Highly recommend without reservation.

We returned from Thanksgiving to find our heat had stopped working. Jeremy was highly recommended by friends and family, which put us at ease.

He arrived promptly, got us running for a couple of days while we figured out what to do next. Easy to work with, he presented options without pressure. The price was reasonable too.

The installation team did an excellent job - professional-looking finish, quick and accurate execution, and no mess left behind. Overall, I'm confident in recommending them to others.

Jeremy and his team replaced our ancient AC system with a brand-new one. Their professionalism and efficiency were top-notch from start to finish. The job was completed quickly, and they double-checked everything before departing. The new unit is working flawlessly - we're extremely satisfied.
