"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!"

We did not want to replace it and he had the parts with him and was able to repair! Amazing! (He also serviced our Sub-zero fridge!) We will definitely use them in the future and highly recommend!"

Customers say: True professional
"Home A/C went out while I was out of town and my son was sweltering at home. Local guy I have used for years diagnosed it over the phone as needing an expensive repair. Contacted Home Advisor for second opinion. Ocasitas Comfort responded to email immediately and was onsite quicker than Jimmy Johns. Pointed out that problem was incorrectly diagnosed and took time to go over everything. Had my A/C up and running in no time for a fraction of what I thought I was going to spend. Very friendly. Could have stuck me up and I would not been none the wiser."
