Testimonials
LMS has become more of a partnership in operating our facility in the best possible way for our customers, rather than just a vendor we call when we need something.
We value the responsiveness, knowledge, and personal connections LMS brings to the table. I would recommend LMS to any owner or property management company looking for a qualified HVAC company.
I can’t imagine not having LMS as part of the team. I tell my Board of Directors that the service provided over the last two years has save the building money. How often can you say that?”
Derek is always wonderful – you couldn’t have a better person – he always calls me – he is awesome.
Gene did wonderful. I emailed Jon and asked for him to schedule us for more services

It is with much enthusiasm that I am writing to commend the services of LMS and their staff. The Hospital has been using LMS to maintain critical hospital equipment of 10 years and we have always been completely satisfied with their performance. They do an excellent job, are always punctual, and offer the most competitive rates in town. I am happy to recommend their services and their staff to any company in need of great service.
LMS is our contracted and preferred company for installation, preventative maintenance and service for HVAC related items simply because of the customer service and knowledge of the parties within their company.
