Had a very good and professional experience with Guaranteed changing out my evaporators. Showed up on time and were very thorough. Also helped that the price they quoted was the most competitive I received. They followed up to make sure everything was running smoothly and I’ll be using them going forward.

Great overall customer service. The technicians were very knowledgeable and professional. They explained things in a way that was easy to understand. They answered every question I asked, and even the questions I didn't ask. I highly recommend GUARANTEED AC for all of your ac needs..

This company is so cool! Corey treated us like family.. The quote was reasonable & we got it installed at the house in no time when the unit went out this summer. Fast, affordable & cold air!

Guaranteed Air is customer friendly and ensure they fully take care of the issue. From setting the appointment, pre-appointment confirmations, and follow up, they are very good communicators. My air conditioner was fixed correctly the first time and I have 100% confidence in Corey's diagnosis of my ac.
