    Great experience with Meade's. They were professional with the winter check of the furnace and did…read morethe best job ever cleaning the 2 stage fan and cleaning the gas burners. In the spring they cleaned all the heat A/C heat exchangers by removing the skins, applying a cleaner, brushing away the dirt buildup and reassembly, My unit is 20 years old my bills are the lowest in my neighborhood. I was so satisfied I signed up for their priority program as additional response protection if there is a failure in the middle of the night or other nonworking time. https://www.yelp.com/biz/meades-heating-and-air-sterling

    I chose Meade's based on their strong reviews for installing a new attic HVAC unit, and the…read moreinstallation itself was smooth and professional. However, the system was not set up correctly from the start. It relied heavily on auxiliary heat during heating and failed to cool properly when tested at the start of summer. When I reached out to Meade's, their technician confirmed that the outdoor unit wasn't operating correctly and that the refrigerant was significantly out of specification. As a result, the system effectively ran in an incorrect configuration for nearly three months during peak winter, leading to significantly higher electricity bills (about 3x normal). Once corrected, the system behavior changed immediately. This was also clearly evidenced through Nest thermostat history, which showed auxiliary heat being used on nearly every heating cycle during that period. I understand that energy usage was higher for many homeowners during the colder months, but in this case the system behavior changed noticeably after the issue was fixed, which points to a setup issue rather than just weather. These were installation-related issues that should have been caught during initial setup. While Meade's was responsive in sending a technician after i reached out to them to get the system checked, there was no acknowledgment of the impact beyond that. Despite the elevated energy costs, no credits or accommodation were offered. Overall, good responsiveness, but disappointing quality control and follow-through after installation.

Everyone at this company is a pleasure to communicate with. They always promptly schedule my service appointments and communicate with me the day of to ensure expectations regarding timing are set. I always have the sense that they are looking out for me by providing feedback, offering suggestions, making any ask that I have a reality (i.e. finding an electrician to help install a new steam humidifier) and not pushing anything on me. Another company tempted me away from them as part of a membership package and failed miserably (i.e. 2.5+ months of waiting for an appointment, a prior day appointment cancellation by them and at least another month wait for the next available date). Promptly at 8 am this morning I called CARES to schedule my HVAC inspection. It was such a pleasure to speak to the staffing lady who so graciously offered me an appointment of TODAY. Wow! Such a treat! The team showed up a little earlier than planned with a pre-notification and quickly and efficiently made short work of my inspection. To top it off, their rates have not changed in 3+ years and was approximately 40% less than the other company's preferred membership rate. There is tremendous peace of mind with this company - timely scheduling, prompt appointment arrivals, friendly and efficient team members and seamless invoicing. Could not be happier to be a Client of CARES once again.

I had…read morefigured it was something simple with the error code I was getting with was 74 no 230v to compressor. I called several other AC repair places and it seemed like they wanted to come in and rip me off and do a bunch of things that weren't necessary, even after I told them the code they ignored me and told me what they thought a really expensive problem was. But with Connor Air, Both the technician on phone and the one who came out to site were very friendly, knowledgeable and honest. Feels like they do things the right way. They explained that the fuse was tripped and that I need to clean the outside of the thing with coil cleaner. Use these guys if you dont want to get raked.

Living in McLean, you always run into the issue that a company is going to come out and up-charge you because of where you live. But Air Control has never been like that, I have always felt that they charge me an great price for whatever issue I am having with my units. The owner, Fred, is the friendliest person I have met in NoVA and bends over backwards to meet your HVAC needs. Fred has done so much maintenance on two of my units that they run like new. We're in the process of having to replace my oldest unit, which is about 20 years old, and he has been very helpful and resourceful on how he will replace them, what he will replace them with, as well as everything you need to know when upgrading to a modern system. Fred is very prompt and hard working, which I find to be lacking trait in Northern Virginia, so when I found Air Control, it actually put my mind at ease when it comes to my HVAC units. Also, Jackie who runs the office, is just as knowledgable as anyone when it comes to HVAC, so it's nice that when I call the office I'm speaking to someone who knows more than just how to set up an appointment and who also does their due diligence on your paperwork and is up-to-date on the issues going on in your house.

    Fred has always been there for us whenever we needed help with our HVAC system. As the owner of an…read moreolder home it's important to keep systems properly maintained and there is no one I trust more than Fred, I recommend him to all of my neighbors.

He was just being helpful and pointed me in the right direction of a FREE repair which he didn't have to do.

Sean went above and beyond and I would highly recommend this company!!

I discovered the evaporation unit to the main floor was running continuously even when the system was turned off. I pulled the fuse and planned to make an appointment, but could not get past the blasted online not. I like to talk to a real person, so I stopped and started looking for a different company. My wife then made an appointment, but for a day I had to be at work. No problem, our college aged daughter was home for break so we kept the appointment. What a mistake! Of course my teenaged didn't know what the problem was. She said that the main unit "was making a noise." The tech checked it out and told her it was okay. I know he looked at it, because the fuse is back in, but dude didn't do anything, not only because the fan Continues to run all the time, but also because he told my daughter that it needed to be cleaned, but that he didn't bring anything to do it. The appointment included an annual service, so what the heck is he doing here without a way to complete a service? I keep a supply of filters in the closet with the main HVAC unit and they say that they changed the filters, but they must have done it at random because some intakes have new filters, some don't, and one upstairs they threw out the old one but didn't put in a replacement! And then they had this sales guy come out and try to sell us an entirely new system, telling my daughter who was there and my wife, who my daughter called on the phone, that the A/C unit only lasts ten years. All the while their own tech is telling us there's nothing wrong (even though he didn't do anything). They took my money for a service they didnt do and they wanted to sell me new systems! No way I would recommend them for anything. I think they behaved this way because they were dealing with women, a young gal at home and a mom on the phone. I hate to think what they're doing to old people and the handicapped. Don't use this company!
