What an incredible experience! Our AC went out during a record heat wave, and after contacting several AC companies, I was getting nowhere. Some never even returned my calls, and the ones who did were booked for months. Then I called Lambert. I left a message on Sunday, and Alan the owner called me back Monday morning! Manuel came out the very next day, diagnosed the problem, ordered the part, and had everything repaired in less than a week. He showed up on time, gave us a courtesy call before arriving, and provided an estimate upfront. Even better, the final cost was actually LESS than the estimate! Manuel was one of the nicest and most professional repairmen we’ve ever met. He was transparent and even took time to explain and show me what the problem was. I was dreading the diagnosis thinking we would have to splurge for a new AC system. Turns out it was the motor. The entire experience was refreshing, especially after the frustration of trying to find someone who could help us during a heat wave and not rip us off based on experiences I've heard from friends. I don’t usually go out of my way to write reviews, but this experience really impressed me. It’s not often you find a company that’s this responsive, honest, and professional. I’m so glad I found Lambert Heating & AC and I wouldn’t hesitate to call them again! We will definitely call them for our next maintenance check.Posted on Google![]()

When one of their technicians was sick, the owner came out to inspect my AC. An owner that can perform every job well, is a rarity. Communication was prompt and professional. The technicians were knowledgeable and polite. Even when they encountered a defective part, they made sure I was taken care of the same day.Posted on Google![]()

This is my first time that I employed Lambert Heat/AC. Manuel (the technician) was through and explained the various services he was performing. I highly recommend this business and, on a yearly basis, will continue my relationship with them!!! 🙂😂Posted on Google![]()

I called Alan from Lambert heating and Air. He was able to come out the next morning and look at our system. I own a bakery so keeping it cool is a necessity. He was able to find that there was a Freon leak in the main unit. Also, the air filter on the roof was very dirty. He gave his recommendations, and was approved by our landlord to do the service, because he came in underbid and was able to do the service the same day. I am very happy with his service and attention to detail. If you are in need of any air conditioning services don't hesitate to give them a call.Posted on Google![]()

We just had a new HVAC system installed by Lambert Air & Heating and had such a great experience with them. Alan and everyone we dealt with was friendly, professional, knowledgeable, and incredibly helpful. They showed up when they said they would, communicated with us throughout the process, and left everything clean when they were finished. You can tell they genuinely care about their customers and take pride in doing quality work. We’re so happy we chose Lambert Air & Heating and would absolutely recommend them to anyone!
