Excellent and Considerate Service!




Jermaine did a fantastic job--he called to let me know he was on his way, was awfully nice, fixed the problem efficiently, and took the time to explain and show me how, where, and how often to replace the filters. Thank you!

Jermaine Allen is an asset to your company




He is thoughtful and well-spoken. These are qualities you might not look for in a HVAC guy, but I will tell you that when the technician has these qualities it makes a HUGE difference. Give this dude a raise or at least recognize him in some way. He showed up at 5 p.m. on Saturday, 1.7.17 to work on my 81 yr old uncle's heating unit but could not get anything done - he said he'd need another tech to come with him on Monday. He called back an hour later and said that he could probably get it all figured out Sunday morning in the daylight. He was back Sunday and got it up and running.

Jeremy is the only servicer that we trust!




Jeremy is customer focused; extremely knowledgeable and the best person to service our two HVAC Heat Pump units. He keeps our units working in top condition and makes sure that we don't run into any problems. He's been servicing our units for many years and we don't trust anyone else but him to do the work!

Great Service--Knowledgeable Technician!




We had a Parts & Labor Warranty with another company whose tech incorrectly diagnosed replacing our new Carrier compressor and wanted to charge for standard installation labor procedures. Jermaine immediately recognized the capacitor wasn't working so how could the compressor be bad? He was a total professional from start to finish!

HVAC Bi-annual Maintenance




Jeremy is a top-notch, totally excellent service technician. He is extremely knowledgeable about the HVAC systems that we have and is always polite and very neat. This is especially important because he has to climb into our attic space to service the attic HVAC unit. We don't have any problems because Jeremy makes sure that all of our components are running in tip-top shape. We only ask for Jeremy for servicing our units.


HVAC Installation




Randy and Joey are excellent installers: polite, knowledgeable, efficient, and extremely neat. During the installation, there was hardly any noise; and they finished up and tested the new system without any problems or re-do's. They installed/replaced all of the old components and put in all new hardware all of the necessary pieces. If you're planning to install/replace your HVAC make sure you ask for Randy and Joey.


Shawn was wonderful





Great service, always here speedily when we call.




I really appreciate the service that Ned and the others at HVAC have given us - we've had "odd" problems with our system, and they are always here quickly and handle our troubles with dispatch. Very polite and friendly as well.


Always reliable!




We have used HVAC Unlimited for several years and can always count on dependable service. Ned is our regular Technician and is always thoughtful, courteous and efficient! We will continue to use them for all of our HVAC needs.


Always Excellent Service!




We have used HVAC for many years now at our church - such dependable, efficient service with integrity - I now use them at my personal residence as well! Highly recommend this company!


he comes when you call them




Ned a very honest and great technician to wrk with


Quick Response




Thanks for getting the heat back up and running in the church's sanctuary. It was getting pretty cold. And the good news is -- it's still running and warm. Blessings!

Great Falls is one of the fastest-growing communities in the Washington, D.C. area. It boasts clusters of medium-density residential subdivisions as well as business parks that ring its major intersections. Undeveloped areas remain heavily forested, and a handful of marshy areas attract mammals and birds in impressive concentrations. At the moment, Great Falls’ population sits near the 15,000 mark. Its population is quite affluent, and CNN Money recently ranked it as the country’s “top earning town.”

Great Falls attracts visitors with sweeping views of the Potomac River’s valley and the beautiful Appalachian foothills. Although Great Falls has a largely pleasant climate, muggy ocean air masses can make outdoor activity uncomfortable during the summer. In the winter, chilly northwest winds have the opposite effect. Regardless of their heating and cooling requirements, Great Falls locals can count on HVAC Unlimited to handle their air conditioning repair and installation demands. With access to Carrier’s full product lineup, the company’s licensed, NATE-certified heating and air conditioning service professionals proudly perform all manner of HVAC-related tasks around the clock.
