Fast and efficient work. Open and honest about the work perform. Reasonable and knowledgeable

They did a great job and what I really like is they called the next week to make sure that Everything was still working fine

Marvin is very professional and does a thorough job. His service is highly admired and respected.

Marvin was very professional, on time and efficient. He reinstalled a wireless thermostat for me after the first professional (?) could not get it to work on both the air conditioner and furnace. It was a challenge for Marvin but he was tenacious and would not give up until the job was completed successfully. I'd call him back again. It's hard to find honest and professional technicians of any type these days. Once you find one you keep him/her around.

Prompt, explained problems and fixed them. Temperature presets maintain a comfortable home. Excellent service with bonus- no fan in ducts = no squirrels banging around making an Unholy racket and hideout removed.

Very professional. Marvin has good knownledge of air conditioning system. Besides doing a good job, he is a good consultant. Following his recommendations will ensure you a well functioning system

I will definitely hire Marvin again for HVAC service. Very professional and let me know about things to look out for before they become an issue.

The AC specialist (Marvin) was professional, honest, timely, well knowledgeable, provided important feedback, and offered options.

He knows his job and was very professional

Marvin called within minutes of my request for a service provider. He came out and cleaned the Furnace. He talked me through what he was doing and showed me the finished product. I would highly recommend that you contact NSB for your service needs. I will definitely be using them again! Thank you NSB Service Tech!

This was an excellent hire with outstanding work and professionalism.

Marvin was very professional. He explained everything and the cost was very reasonable.

Marvins team was great! They cleaned up well and everything went wonderful! also he called me the next day and checked in to make sure everything was working properly. I was very pleased and they did a great job!

My tech was great, super polite, super knowledgeable. Went above and beyond to complete the task without charging me more then we discussed. If needed I will only hire NSB Service Tech.

Marvin was very nice and very professional. He showed up the day I called him. Fixed the problem immediately. I definitely would recommend him !

Marvin offered Incredible service, with clear explanations as to the issues being addressed and repaired. Very generous pricing, and incredibly warm, positive, and engaging attitude working under incredibly unpleasant weather conditions. He was very responsive to questions and texts, and knows the meaning of customer service. I could not recommend more highly for any HVAC repair job.

Did not follow up on additional work that was requested.
