What our Customers are Saying

  • I called GLM Heating and Air Conditioning Inc, the person who answered the phone proved to be polite and efficient. A guy from the company came over the same day after my call and took a look at my HVAC. He fixed the problem right away. Definitely would call GLM Heating and Air Conditioning Inc again if I need a heating contractor!

  • My air conditioning broke down a last month. I called GLM and came Prompt, Professional, Thorough. I called for an appointment and was able to get someone out the next day even though we are at the beginning of the busy season. The technician quickly identified the problem, had the part, and fixed my air conditioning. He was also able to help complete the warranty paperwork. Great Service!

  • GLM were contracted out to install a 5-ton roof top combo unit in Beverly Hills. Gaul was very professional and took the time to answer all of the questions that I had about the unit and installation process. The installation went smoothly and Gaul returned over the course of the project to make sure the unit was operational. I'm very happy with the level of service and quality provided by GLM and would recommend them to anyone looking for affordable and high end HVAC work done.
