Some Of Our Testimonials

This is just to say how once again we are really impressed by our heating/AC contractor who’s taken care of our units (and replaced them when aged out) for many years.

We called this morning to say one thermostat was blinking: Call technician. The service rep came right out. Under warranty, so the new compressor was going to cost us $900 and it would be installed Monday or Tuesday. Fine, we thought.

Then they called back. A little research showed we would only have to pay $250 AND it was being installed today!

If your unit(s) stall, I think you’ll be happy with ADCO (of Manassas.)

I wanted to write and tell how much we are enjoying our new geothermal heat pump.  For the first time in the 17 years that we’ve lived here, it’s nice to finally have warm air coming out of the ducts.  We are also getting air from the upper level ducts, which we have never experienced before.  You and your engineers did an excellent job in determining the setup for the house.

I also wanted to let you know how smoothly the installation went. It’s hard to believe that in little more than a day, your crew removed the old unit, ran the new coolant lines, reconfigured the ductwork, installed the new unit, and put in a new thermostat.  We noticed a minor problem with the installation, but a crew came to the house and fixed it the very next day.

I’ve given numerous tours of the geothermal unit to family, friends, and neighbors (and our former heat pump guy!)  There is a huge interest in this technology, especially during this time of rising energy prices.

Dealing with you and adco has been such a pleasant experience that I have been recommending you to all of my friends.  Thank you again for a job well done!

I am writing to express my positive experience working with members of your organization. The entire process was extremely smooth, hassle-free and professional. It started with George in Sales who came to our house to discuss our options and provide a proposal. He followed up with me timely to see if I had additional questions and exhibited a sincere interest in our needs. Next, Kendra helped us in obtaining financing and scheduled our work according to our schedule and availability (which required a Saturday installation date). Finally, Mike and his installation team completed a professional job that exhibited care and attention to details. Mike was receptive to questions I had and showed us the operations and components of our new system.

Thank you for a a job very well done. I look forward to recommending your company to others who are in need of HVAC sales or services.

I have been with this dealer since 1984. In addition to regular service and maintenance, they have been there for me in emergencies. As my HVAC equipment aged/wore out, I purchased new from this dealer. They have always served me very well…the company and their staff. I highly recommend them.
