The technician evaluated the problem and concluded the compressor was not working and provided a couple of options. We proceeded to replace the existing unit because it was near its end of life and replacing the compressor would not be cost effective in the long term. Air Treatment Heating & Cooling was able to replace the entire unit during the peak summer season within a couple of days. From start to finish, personnel was friendly, professional, and installed the new unit with no problems. We will definitely use Air Treatment Heating & Cooling in the future, and would recommend their services to others as well!

I cannot recommend this Installer highly enough! Do not waste your time with the other guys in…read moreNorthern Virginia. They installed two HVAC units in my home. Anytime I have a whisper of a problem they are there the next day to make sure everything is running smoothly. They never ever try to upsell you or make you buy something you don't need. They offer a full professional service and then after service that is beyond anything I have seen. Save yourself sometime don't bother with the others from the cost point of view they beat everybody I had. From a service point of view I couldn't ask for better so thats that! Like Nike said JUST DO IT!

I'm leaving a review based on my prior experiences with KCS (have used them since we purchased our…read morehome in 2020). We got their base maintenance plan with 2 inspection services each year, and used that for about 3 years (no real issues to fix.) During one inspection in 2024, the tech realized that our furnace water pan had filled (but not so high it shut off yet) and he helped identify the problem and luckily was able to fix it the same day (no parts/ charge.) He suggested in a non-pushy way that it really may benefit us to up our plan to the higher one (almost double the cost/yr, so a little scary) because we're probably entering the zone where larger repairs may start for our furnace and the plan covered most of the types of parts that would be in a significant repair. He seemed knowledgeable and trustworthy, so we decided to at least do it for a year. We were very lucky, because the next year was the epic winter - the furnace went out/ our YouTube tricks didn't get it running, and the red plan ($500/yr) meant we pushed to the top of the queue and got someone out when the temp was dropping in the whole house. Apparently the part needed to fix it was over $1,000 (not including install), and that was covered in our plan. So that proved the value for us! I know they were recently acquired/ merged with FH Furr, so it appeared that our online requests for service on the KCS site were not actually being seen/ addressed. When I got time to call over, the former red maintenance plan was unfortunately no longer sold by this new company. I got the "gold plan" which includes 2 HVAC inspections, a plumbing inspection, and an electrical inspection for honestly a price that is so cheap I'm worried it's going to be an upselling scam :/ so I'll update this as needed in the future to help others who may wondering if this new company will have the same service quality as pre-acquisition.

I am extremely disappointed with my experience with Mannix Heating & Cooling. I contacted the…read morecompany regarding an Aprilaire humidifier recall because my humidifier was not working. As a homeowner, I don't know whether the issue is the recalled electrode, the humidifier itself, the wiring, or the HVAC controls. That's exactly why I hired an HVAC company--to diagnose the problem. Instead, technician Silvio Guerrero immediately stated there would be two separate charges before inspecting a single component. I even suggested we set the recall aside and simply use the visit to diagnose why my humidifier wasn't working. Rather than inspecting anything or explaining what the charges covered, he repeatedly said, "It's two charges," stated he was very busy with other service calls and didn't have time to deal with this, told me to call the office, suggested I hire another company, and left. My HVAC system itself is brand new and working perfectly. My humidifier, however, is wired into the HVAC control board. I was not asking for an HVAC repair--I was asking for my humidifier to be diagnosed. If checking the HVAC control board as part of diagnosing the humidifier required an additional charge, that should have been explained after inspecting the system. Instead, the moment the discussion involved the HVAC control board, it seemed to automatically become a separate charge without anyone even looking at the equipment. What made the experience even worse was management's response. Instead of listening to my concerns, I was told I was "argumentative" and accused of "double dipping." That accusation was both unfair and insulting. I never asked for free work or refused to pay for legitimate diagnostics. I simply expected the technician to inspect the problem, explain what he found, identify what was covered by the recall, explain any additional charges, and then let me decide how to proceed. This entire experience reflected poor communication, impatience, and a lack of professionalism from both the technician and management. Customers deserve a proper diagnosis and a clear explanation before being asked to authorize additional charges--not assumptions, accusations, and a technician who walks away without inspecting the problem. I have completely lost confidence in Mannix Heating & Cooling and will never use this company again.

I got four bids on the replacement of my 2 residential HVAC units. Mannix's representative, Mr…read more Kapur, was the most impressive and well-informed among those coming to my home. He suggested a method that would save me cost and aggravation in the installation process (viz., the closet housing one of the units had a narrow opening and some other estimators wanted to rip out the door frame, which Mr. Kapur determined was unnecessary.) The pricing of replacement HVACs was competitive and the installation crew was respectful, hard-working and very competent, finishing all of the project in under one day. I am very satisfied with everything Mannix did on my property.
