HVAC Services

EMJAY’s service team is a highly technical group that goes beyond simply maintaining and servicing HVAC equipment. With our maintenance program, our highly-trained staff will invest into your facility by learning its operational patterns in order to help you find the most efficient and effective way to operate your building's largest consumer of energy. Our company culture of helping our clients creates a unique partnership in which our technicians have a vested interest in your facility’s success. This unique relationship is seen in countless facilities from school systems to hospital centers, and privately owned buildings where these partnership foundations are now decades old built on trust, dedication, and exemplary performance. EMJAY uses the latest in technology, not only for diagnostics and repair, but also for service reporting. By using a paperless reporting system, a service report will be provided complete with a signature while the technician is still on site. Our service begins and ends with care and trust, but our team will really win you over with our capabilities.

I want to let you know how great it is to work and have such a strong relationship with EMJAY. At the college today we had an issue with one of the rooftop units and I called the service team who jumped on finding a way to resolve the issue we were experiencing. Within 45 minutes service had contacted me to let me know they had a service tech on the way, and two hours after the original call the issue was resolved. This is an issue that was easily resolved with the help of EMJAY. The quick response time made on a cold day is much appreciated and as usual, you all went above and beyond. Thank you all for always being there for me and the college when we need your help!

I just wanted to thank you for the great job Matt and Kevin did completing all the PMs. They really helped me out working around all the tenant’s schedules. You have a great team and we are happy to be working with you. Thank you .

You guys are on “top” of my list and my radar. I am very pleased with the working relationship.

Since working with EMJAY going on two years, it has been an absolute pleasure. EMJAY is very attentive, informative and pro-active in their maintenance approach. Their techs are full of knowledge and bring a matter to engineering/management’s attention before it becomes a true problem. Looking forward to working with EMJAY for many years to come.

Hi Derek,
I would love to tell you about our experience with your service team. I switched all my Maryland properties to EMJAY after working with you and your team on our new building in Germantown. The service you provided in our new building was amazing, always responding immediately and very proactive. Since EMJAY has been maintaining our HVAC equipment we have not had one breakdown. Your technicians are well trained and thorough and the office staff always alerts us to when they will be onsite. When our hot water boiler failed in our Lanham building you personally helped us get our unit up and running in a fraction of the time our previous vender quoted. EMJAY has been the only vendor our corporate HVAC team has been satisfied with. I’m a very happy customer!
