If you're looking for a business that strives for the best quality and customer service then L&S Heating & Cooling LLC is your best bet. My experience was absolutely amazing! I called on a Saturday to have my AC checked... Read More due to no cool air coming out and was originally quoted a 6pm appointment. To my surprise Lalo was able to stop by and diagnose my problem only 1 hour after I called L&S. Not even Door Dash is that fast! After diagnosing the issue he explained my options. Being that I had already passed 10 years with my old unit it was time for a replacement. We discussed different options and he explained the pros and cons of each one. I was going to be without AC for a couple days until the install date, no big deal since it hadn't been too hot yet. This is what sets L&S apart from other companies, Lalo messages me on Sunday that he found a part that could get my current system running temporarily until my new unit was installed. He went out of his way to make those days I originally was going to be without AC, comfortable. L&S has that personal customer connection that you don't find anymore. The professionals that installed my new system were absolutely incredible. they arrived right on time and cleaned up their work areas after they completed the job. Top notch professional service. I am forever a loyal customer after the experience I had.
Honest, reliable and quick! Lalo and his crew are knowledgeable, and always get the job done right the first time.
