We Stand By Everything We Do, Read Our Reviews

On March 25, 2022, Clover Services installed a U/V air scrubber to purify the air in one of our HVAC systems (we have a 2-zone system in our DC rowhouse). They also did a thorough seasonal check of both systems. In addition, they strengthened the supports for the unit that sits on our roof to insure that strong winds won't move it around. Ryan and Brian completed with work--extremely professional, efficient, and easy to work with. Clover has installed and maintained our HVAC systems for the past 8 years, providing extraordinary service to us throughout that time period. Ryan, incidentally, has been the primary technician responsible for maintaining our system since 2014, a testament to Clover's commitment to retaining top talent and delivering consistent high-quality service. Ryan is a superb communicator. He takes his time explaining his work and walking through recommended repairs. He is transparent and patient. And, although our 110-year old row house can prove somewhat challenging for modern HVAC, his work has proven to be of the highest quality and reliability over the years. I would recommend Clover without hesitation to family, friends, and colleagues.

Clover was amazing from start to finish! Their customer service was great, they were prompt in coming out for the estimate and were on time. The plumber walked us through the work they would do and we received the quote almost immediately. They were able to schedule the work immediately as well. They were on time and were great at finding what they needed (without any assistance or guidance from our condo on where anything was located). The were right on with their estimated time of completion, and the work looks amazing! They had to replace a bunch of pipe, fix our main water valve and install a new water heater. Great job guys, I will definitely be recommending and using your company again!

Clover responded very quickly to our problem with our heat pump. They were accurate in notifying us about their arrival time so that we didn’t have to wait around all day. Brian and Austin were courteous and professional and repaired our system as they explained in clear and unhurried manner. We would hire them again based on this call.

We found Clover on Google this morning & needed them to come out before 4pm so that we could open. To the general public. They were very helpful over the phone, super responsive & professional! We really appreciate all their help today!

My tech was super. He diagnosed the problem, found the part, changed my filter in a timely and cost effective manor. He wore a mask and coverups over his shoes. I’ve used them before and will definitely use them again.

I had a couple of issues with the AC and Plumbing at our Condo in Reston. I have used Kiddco Plumbing in the past and was very disappointed with their service. Luckily I noticed the bright green Clover Truck in the community parking lot. When the AC went out yesterday, I called Clover and I was quickly able to get an appointment for the AC. I was impressed with the technicians and I signed up for the Gold service package. The AC was serviced, lines cleared, a new circuit board installed and the thermostat replaced. I then had the Clover Plumbing Specialist do a plumbing assessment for the condo and recommended new fixtures and even proposed design suggestions. I was extremely pleased with the service I received from Clover.

Ryan came out for a free estimate on zoning the HVAC on my floor so that I could have my own thermostat to control my suite independent from the rest of the floor. He took a generous amount of time diagnosing the problem, including climbing up a ladder and getting up on the roof to inspect the system in place. He diagnosed the problem and instead of pushing a much more costly, found the least expensive and most cost effective solution. His price estimate was given later the same day, and the quoted price was fair. Thank you, Ryan!

Clover Services have been great to me. Whenever I have a job I can't do on my own, I call them. Ronan has come out several times and done excellent work.

Clover has always been my go to. Great customer service and great technicians!! The technician that has been working with us is Ryan Kibler and Ryan is the best that I have worked with. Ryan takes his time to explain the issue and also makes sure you understand the issue. I would 100% recommend Clovet and I would also recommend that you request Ryan as he is some you can trust on what he tells you. Goes the extra mile!

Over the years Clover Services has proven to be the most reliable, professional, capable, and cost effective repair service we've ever used. The last time they came to fix a plumbing problem the technician went way above and beyond in ensuring the difficulty was resolved to our total satisfaction. I can't recommend these folks too highly !

Clover is our go to plumber. Many years ago they solved a plumbing / water issue numerous other plumbers couldn’t figure out. In this case they quickly and efficiently fixed a faucet for us.

Clover Services was great. They were referred to me by a neighbor who had used them before several times. The plumber, German, was timely and professional, patient in answering my questions, was able to diagnose the source of the leak quickly, and efficiently repair the issue. He also was able to take care of a few other minor plumbing tasks that I have been waiting to do during this same visit. I especially liked that the company sent me a picture of the plumber that was arriving so I knew who to expect. I will most definitely call Clover again for any future plumbing needs.

We love the guys from Clover - always efficient, detailed and NEVER try to up sell like so many other plumbing and HVAC companies around here. Highly recommend them

Clover Services is a local Fairfax company, small enough to be responsive and large enough to be able to cover every aspect of HVAC that I have needed. Their prices are fair, and they've stood behind work, coming back to check and fix things when original work needed it. Their technicians are polite, clean/tidy, and willing to explain the repairs at the level I need. I've had entire systems installed by them, and many small repairs. The annual HVAC contract has been worthwhile for getting the service we need prior to the cold and the heat.

Ryan was most professional. He made a quick diagnostic of the problem and gave me options to consider. He talked through his process and made sure that I understood the corrections and the expense. I will be calling Ryan from clover services again. Thank you!

Clover services are outstanding, and I highly recommend them. They did some work on a dryer gas line. All interactions with Clover were great, though the technician did not do a great job on the first pass. What is so impressive about Clover is that when I called them, they sent out a different tech who completely re-did the work to a really high quality level. Though the first pass wasn’t great, Clover’s approach to dealing with it demonstrated to me that they are a company to be trusted and we will work with them from now on.

Clover was recommended by a neighbor, and I was surprised that our technician Ryan new them by name, including what type of heating system they had. Our appointment was for second estimate, as another contractor recommended that we replace our furnace and hot water heater (turns out out water heater wasn’t permitted and wasn’t to code fir the space). Ryan corroborated the recommended water heater diagnosis, but reassured us that furnace was fine and likely to have more life in it. He explained things clearly, listened to us, and unlike our other estimate, wasn’t a hard sell.
