Richard and Charles from the Gaithersburg office just installed a mini split system in my personal training studio. Both men went above and beyond to complete my job. In fact, they encountered a technical difficulty and remained on the job until it was completed. I would highly recommend you request Richard and Charles from the Gaithersburg office for your upcoming HVAC job. Overall, my wife and I have been customers of Mannix for five years. We have only used Steve Brimsfield, Mannix’s sales rep, for three jobs. Most importantly, purchase the service contract that entitles you to a spring and fall maintanence. Mannix’s customer service is over the top. Give them a call today.

Exceptional experience from Mannix in Gaithersburg!! We just put in a new system after working with Steve who did a fabulous job of educating us and helping us choose just the right HVAC for our home. Billy and Matt did the installation. They arrived precisely when promised, were efficient, friendly and respectfully put on shoe covers the moment they entered our home. We couldn't have asked for a better value (we did our homework on pricing and best equipment) or a smoother process. They turned a potentially daunting task and investment into one of our best home maintenance projects ever!

Can't say enough about Mannix and the entire team in Gaithersburg....Steve, Richard & Charles are top notch, professional and experts in what they do! They replaced my AC & Furnace in my attic almost two years ago and just finished installing the AC & Furnace in my basement. Will happily refer them to my friends and family! Thanks!
