Furnace Repair Lowell

Very professional and great service. My heating stopped working and my neighbor suggested I call Alex. I called him for an emergency situation, and he came in no time. He did a great job fixing it. He is very knowledgeable, and I highly recommend him.

When our heater broke down in the middle of winter, I was worried. But Greater Boston HVAC was at our door within hours, and they fixed the issue seamlessly. Truly professional and efficient!

I've been using their maintenance service on a yearly basis for many years. Each inspection is thorough, and they take the time to explain everything. It's rare to find such a dedicated team these days.

During the scorching summer, our AC unit gave out. Not only did Alex provide a speedy repair, but he also gave us tips on keeping our system running smoothly. Exceptional service!

I was initially skeptical about switching to a new service provider, but their Greater Boston HVAC proved me wrong. Their attention to detail and customer-first approach have made me a loyal customer. Highly recommend!

I just have to express how wonderful this company is. They are contracted with my property management. My AC went out this past weekend on the extreme heat. They scheduled me the earliest they could, and were very friendly. They were on time and able to quickly fix the problem. I am so grateful for their quick response. I would recommend them to anyone.

National Heating and Air is a top notch business! The estimator Rick was thorough and gave me several options, no pressure and really listened to my needs! The installers Dustin, Greg and Tim we so efficient, polite, respectful and did a great job. They left my house neat and tidy with only minor disruption. They were great to work with! My new system works great, quiet and very even heat throughout the house!

I have been a customer of National Heating and Air Conditioning for several years. One of their technicians, Jeff, has done most of my routine maintenance and is always professional, very knowledgeable, personable and usually arrives early! He recently installed a new motor in my Heat pump and did a great job. This was during a period of 100 degree weather. He identified the trouble, ordered the motor, and arranged delivery during the time he was working on the unit the next day. I had not expected to find relief from the heat so quickly. Thanks, Jeff! This is a honest company with qualified technicians. You can count on them to do their best for you.

From beginning to end this company did an amazing job! They are very professional, yet so kind and friendly. Even let us borrow heaters to help keep our house warm until we could get the new heating system installed. Use excellent products and everyone from repairer, estimator, office staff and the installers were all awesome. Really appreciated when they came to the house they always wore masks without being asked. A huge bonus! I would not hesitate to recommend them.

I have had National Heating and Air Conditioning technicians out to my home in Ashland, OR twice this summer. First to do an initial inspection and service on my air conditioner. A couple of months later my HVAC fan motor needed replacement. Both times they responded promptly and they were knowledgeable. Each time they understood what I wanted and took care of it quickly. I found their charges for parts & services quite affordable. I am happy to depend on their services again for any of my HVAC needs in the future. I can recommend them highly!
