Great and honest service. Our AC stopped working & upon assessing the situation it was observed that the drainage pan had filled too much so it shut off the AC. The rest of the system was checked out to be ok. Several other companies were called and messages left with no return calls at all. These are the big name guys who claim to have 24hr availability. The only thing they have is answering service but no return calls. Nascair is local, reliable and can be trusted to honestly tell you what's wrong. Glad to have found such a good company. No need to look any further.
