    Quality of work was terrific and Moe even worked closely with me as I was out of town and in need of immediate service.

    Earlier this week, my hot water heater failed (significant leaking) and it needed to be replaced…read moreasap. I reached out via Yelp to five different plumbing companies in the NoVa area for quotes and an idea of when they could help me out. Arlington Plumbing Heating and Cooling replied to my inquiry within minutes. I received quotes from three companies and Arlington Plumbing's quote was competitive. I was sold by Arlington Plumbing's promptness to my request and their professionalism on the phone. It was 9am, and I was told I would have hot water by the end of the day. Arlington Plumbing Heating and Cooling delivered. I was given an estimate of the time they could do the work and over the course of the day I was contacted a number of times via phone that they were on track. Arlington Plumbing arrived at the agreed upon time, did the work with a professional manner, they did a great job of cleaning up, and I had hot water before my spouse arrived home from work. My spouse thought I was a hero, but it was really Arlington Plumbing Heating and Cooling that was the hero. Thank you. I will definitely use this company again when I have my next plumbing issue. I will absolutely provide their contact information to my friends and neighbors when they have an issue.

    I initially thought about taking off a star because John arrived outside of my appointment window,…read morea pet peeve of mine, but then I remembered a few things: he came on a Sunday, on less than a day's notice, Arlington is very far from Upper Marlboro, the appointment before me went over, which can happen to anyone, and most importantly, small businesses are the backbone of America. John was very polite and immediately told me my HVAC closet smelled because a mouse died in there. He also called a relative while at my place and on the way home to give me their suggestions on dealing with the smell, which has nothing to do with HVAC and is above and beyond in my opinion. Yes, I did have to pay the $100 fee to come out. I paid in cash to not have to pay the 10% processing fee. I was fine with paying this to have someone come out so quickly, and on a Sunday. Would call again. When my problem actually involves HVAC repair.

The only reason I wouldn't give it five stars is because whomever I booked with didn't properly explain how the pricing worked beforehand which would have influenced my decision to use this company or not. The overall total was pricier than expected due to this and the price of parts but well worth it as my AC is functioning better than ever. Other than that great work!

    23 May 2022: This entire team, the scheduler and those who arrive to service my home's equipment,…read moreis nothing short of fantastic. 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.

    My fuse was broken on my AC unit outside and they came and replaced it quick and easy. 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.
