After having what I thought would be a straightforward check of my gas boiler furnace to prepare for the winter, a local company advised me I would need additional replacement and repairs, resulting in a $3,000 project. Decided to contact additional companies who could work with older boiler systems and in addition to a much lower estimate, Mirko of PCK was able to schedule his service and it was done in good time. The upstairs heating is so much better now! At a significantly lower cost. I know this boiler will need to eventually have to be replaced, and I will count on Mirko for the work. read more

Mirko installed new Space Pack HVAC unit at my house. On time, without any trouble, clean job and efficient crew. I loved it. Five stars !!! Definitely worth the price given. read more

Mirko with PCK HVAC has helped me for years! He helped me install my new HVAC system in my house without any bulkheads and it's perfectly balanced on both floors (not hotter on one floor). He has also helped me with many client's HVAC systems; he is able to troubleshoot the most complex issues and explains the options very honestly; his prices are very fair! read more

Mirko is a godsend. He advised us about how to upgrade our home's heating and cooling systems, which hadn't been touched in decades. Then he put that advice into practice: he replaced our gas boiler with an electric heat pump and mini-splits and our gas-powered water heater with an electric one. The result has been better, and more consistent, heating around the house. Mirko was even able to remove the 100-year-old radiators and pipes from our home, freeing up valuable space. I'd unquestionably recommend Mirko for any HVAC needs. read more

Hard worker, honest, reliable, and a fair price. Put in a new boiler for me and installed some custom radiators.

Mirko recently replaced out failed mini-split. Our 7 year old Mitsubishi failed and Mirko replaced the unit with a new system. The problem was the new unit required some good-old-fashioned skills to make it fit in to the old lines and Mirko was innovative it fit the new neatly into the existing lines and space. Mirko clearly knew what needed to be done and went to the task. He didn't just do the minimum, but replaced a few parts that did not meet the new code standards with compliant parts. I have been a field service tech for over 40 years (not on HVACs) but I can tell a true, competent, and skilled technician when I see one and Mirko is exactly that! Without reservation, I recommend Mirko. Period. read more

I can't recommend PCK HVAC enough! Mirko came to our house after a recent purchase to service our HVAC. He spent several hours working on our unit and went above and beyond our expectations. He is prompt, professional, and a pleasure to talk to. We enjoyed his service so much that we used him the following week to work on our dryer connection that required several hours of work to bring everything up to code. He does not cut corners, charges a fair price, and I would highly recommend him to anyone. He is a skilled professional! read more

Mirko is awesome to work with! My wife and I discovered PCK a couple of years ago after having a large HVAC company come out to inspect our AC system, which was freezing up. The large company told us that our AC was shot, could not be fixed, and tried to sell us on a $36,000 lease for a new unit. We sought a second opinion from PCK and Mirko came out to look at our system. He took a look and let us know that, while our AC was old, he should be able to get it working again by adding some Freon. A few hundred bucks later and our AC system was cooling the house again! We've had Mirko come out to do work at our house a couple of times since and he's been punctual, professional, and reasonably priced each time. When our current system finally bites the dust, we will have PCK replace it! read more

Wednesday morning I had water all over the kitchen counters. At first I thought it was a leak coming from the upstairs bathroom so I reached out to a plumber to take a look at it. Plumber couldn't come out until Thursday afternoon. He confirmed that it was not a leak from the bathroom. Upon opening ceiling we found Hvac and he concluded it was coming from the air conditioning unit. I found Mirko on Yelp. I reached out Saturday morning and he was able to schedule me for Sunday afternoon. He was quick and timely to respond to my yelp inquiry and provided a fair and reasonable service call estimate. I truly appreciate his honesty and work ethic. He was able to correct the issue and offered advice on how to keep my PVC pipe clean. I also appreciate that he was able to fix the rattling from outside unit. We laughed about my "stone". Great guy I would definitely recommend him!!! read more

Mirko was one of three HVAC companies we met with about our system replacement. He was extremely thorough and professional and gave us a very reasonable quote. His work was great and he cut absolutely no corners. He noticed and fixed issues that I had to point out to the other potential companies. He worked very efficiently and even got the A/C working midway through the job, which was a huge help on a 95 degree day so we could be cool until he came to finish the job the next day. He made sure to get all the needed permits and scheduled the inspector for us. I highly recommend working with him, Mirko definitely takes pride in his work and does a really great job. read more

We have been working with Mirko at PCK HVAC and he has been amazing!! We are doing a full replacement of our AC unit and Furnace which are from 2003. He has been so responsive, helpful, great at explaining what needs to be done, on time, leaving the space clean, reasonable pricing and he works on Saturday's. I can't recommend him highly enough! read more

Can't recommend Mirko enough. He was communicative, punctual, honest, friendly, fast, and did great work. After a different company recommended we replace our entire system, Mirko was able to fix it by just replacing the evaporator coil -- for $75 less than he quoted! He went over all our options and advantages and disadvantages of each and never tried to push anything on us. It's only been 1 day since the repair but everything looks well done. read more

Mirko is by far the most reliable, honest, and knowledgable HVAC contractor we have ever used (and we've used a LOT!). Specifically, Mirko helped to troubleshoot a persistent furnace issue we had at our rental home (when the heat keeps going out in the dead of winter, that's a biiiiiig problem!). After several other HVAC techs had us replace various parts in our fairly new (only 1 year old) gas furnace, Mirko was able to diagnose that the issue was from our gas supply, not the machinery. I won't go down the rabbit hole of what transpired afterwards, but he saved us a lot of money in unnecessary "fixes" while correctly finding that the issue was with our gas company supplier. He was on call several times afterwards to answer other questions and concerns and was always incredibly responsive. Unfortunately now Mirko does not service our part of DC, but we are so thankful for the times when we were able to hire his services. Can't recommend highly enough! read more

Mirko diagnosed and fixed my old old AC unit at the start of humid season when it inexplicably stopped working. He found some faulty wiring that a previous owner had DIYed wrong that could have led to serious electrical issues, not to mention unbearable heat in the house. He explained everything as he went and didn't stop until he figured it out. Outstanding knowledge and very polite and personable. Other companies would probably look at my old system and shrug and try to sell me all new stuff, but he saved me money and fixed it fast! Thanks! read more

We used Mirko for a recent install of a ductless minisplit system. I could go on and on, but to be clear, Mirko and PcK HVAC is a stand-up, professional service! We couldn't be more pleased! Some highlights: -Fantastic bid price...doesn't overcharge for high-quality, superior work -Responsive to questions/concerns -Follows-up and comes out almost immediately if there is a problem -Always timely -Not invasive (this work can be messy, etc., but the PcK staff is efficient, works quickly in the home, and leaves things how they found them) -Friendly! (can't really overstate how nice it is to have great customer service, which they do) read more

Mirko is always willing to work with me on the most complex heating and AC issues.

I got several quotes for a new heat pump system, and Mirko was the most prompt, the most honest, and the best value by about $1000. He actually offered to fix my existing system when others said it couldn't. After seeing the two quotes, I went with a new Bryant system, and he did it fast, he did it very professionally, and not one penny more than the quoted price. Every contractor should be Mirko. read more

Mirko was a lucky find last year when I needed my 30-yr old dual system a/c replaced. He came up with a creative solution for new duct work, and has followed up to fix small details. I was so pleased with his work on my home that I asked him to address major problems I was having with my finicky Raypac boilers in a rental property. He was knowledgeable about these fairly esoteric boilers, and solved a heating emergency for my tenants. All and all, a talented heating and a/c pro, and reasonably priced. read more

I'm always nervous about reviewing a contractor I like because they are SO hard to find and the good ones are always booked up. Mirko deserves it though, we've had service done by 3 different local HVAC companies and Mirko was the most straight forward and knowledgeable about his work. His prices were reasonable compared to others and he made recommendations that have helped us save money the past couple years. You can book him within a few days notice, he always comes on time and can be relied upon. I wholeheartedly recommend him, but please don't use him so much he's too busy when I need him. :) read more

We hired Mirko to replace our very old gas boiler and water heater and we couldn't be more pleased with the entire experience. From the initial meeting, it was very clear that he is extremely knowledgeable about his trade. Not only did the installation of the new boiler and water heater go smoothly, he was also able to suggest ways to remove redundant piping and he added separate zones so we could better control the heat in different parts of our house. The install passed inspection and the inspector even commented on the high quality of the work. We were also please with Mirko's communication (responsive), work ethic (even worked on Saturdays), price (competitive), and work habits (kept the workspace clean). He was very detail oriented and told us that he approached every job as if it were his own house. He will definitely be our go-to person in the future. read more

When our A/C unit went out on a 100+ degree day, I contacted Mirko from Pck HVAC. The first company I called said they were unable to repair my unit since it required a special level of training that they did not have. Mirko from Pck is a Master mechanic and has the certifications for advanced systems. When he came out, he noticed problems with the original installation, which caused the unit to fail. He ordered me a new compressor unit that was designed for our existing HVAC system and installed it. He then registered our unit for us with the manufacturer and sent us an email confirmation. His quoted price is what we paid, even though he spent a little more time fixing issues from the original installation. In summary, his price was good, he was thorough, and he was fast in his response time. He owns the company and takes a great deal of pride in his work. He truly loves his work and it shows. He is VERY knowledgeable and his prices are great. You won't be disappointed if you hire him. read more

My furnace stopped working and PCK was able to make time in his busy schedule during a cold spell to repair it the next day. I would highly recommend this company as they are top notch. read more

I echo all the other positive reviews. Mirko is one of the most upstanding people, let alone tradesmen, I've ever met. I found out about him when we wanted to install a Nest thermostat. Since then we have signed up for bi-annual HVAC inspections, and just this past week had him install a new A/C, wanting to move away from our old, but still functional, Freon unit. He is totally thorough, and spends as much time as necessary to do the job to a degree that he sees fit, even if it's longer than he originally anticipated. And, he is true to his quoted price even if it takes longer. He's really interesting to talk to; I always look forward to his visits. read more

Both of our heating systems went down the day before Christmas! PCK HVAC responded promptly and were able to come in and fix both furnaces. Mirko, the technician that came in, was very courteous and was able to fix both units at a very reasonable price! He noticed our three kids and also made some kind recommendations to install carbon monoxide detectors and replace our very old fire detectors- he did this looking out for my family, not because he sold any of the detectors. I will definitely be calling PCK HVAC again for any of our heating/cooling needs. THANK YOU! read more

Mirko was a life saver. Another contractor failed to service the warranty on my HVAC system. Mirko was able to come in and save the day. He clearly has an expert understanding of HVAC systems, the parts, and the physics that go into them. He was able to diagnose and fix two independent issues in my system and I trusted him to do the work and keep the price low. He clearly laid out the options for me when the freon in my system was leaking so I could make an educated choice about what to do. He could have pushed me toward the more expensive route for fixing it, but instead gave an unbiased consultation that ended up saving me money. I'll certainly call him next time if anything else happens. read more

I love PCK HVAC. Recommended to us by our real-estate agent (who's dealt with all manner of house issues and repair companies) we've been relying on PCK HVAC to help us with our 12 year old auxiliary heat pump since 2019. PCK HVAC came out to trouble shoot our AC/Heating system and determined the fan motor on the outside unit needed replacing. Cost effective fix, and it continued to work. Over the years the same unit would have other problems related to the refrigerant but PCK HVAC would consult with us and help us troubleshoot it over the phone. Finally it came to replace the unit, and PCK HVAC informed us of pandemic scarcity and price increases but worked with us to lock in a competitive price. Replacement of the unit was quick, all permits handled, new system looks and sounds great, and has a great warranty. He fixed things I wasn't aware were broken as well, like a cracked drain pan under the inside unit, a condensation drain line that wasn't up to code, and all as a part of the existing replacement contract. I have absolutely no problem recommending PCK HVAC for your HVAC needs. Straight forward, hard working, honest, and reliable. read more

Mikro at PCK HVAC, LLC did GREAT GREAT GREATwork at my condo. I really think he is a honest, and detailed professional. Truly a blessing to find. I had an old terminal heating unit at my condo, that was not sealed off properly to the elements and basement. As a result, TONS of spiders had gotten in the unit, and started getting all over my home. After searching where they were coming from I found the source- my heading unit! I had taped off the whole unit with garbage bags until Mirko could inspect and give me an estimate. Even when he came for the estimate, he was careful not to remove all the tape I had put up as a temp. solution for the spider problem. He had to get to the unit to see the power source and unit ID number but he was great about being careful. I was out of town when he came to do the work, but was finished way before I expected and sent me very detailed information with photos on the status of the job. It was great. He really did a very detailed job to make sure the old frame was cleaned, sealed off PROPERLY THIS TIME and the unit was caulked off totally. I really appreciate the fact that he did such a truly PROFESSIONAL job with the installation. I plan to use him with any HVAC need in the future. Such a blessing!! read more

Mirko at PCK has worked on our house on three HVAC projects and each time, he is timely, professional, and does excellent work. It is in his nature to complete work to a high standard, which I've found to be a rare quality in the DC contractor world. Also unlike most DC contractors, you won't get an experienced person giving you a quote and then a teenager showing up to do the work; you will get Mirko and his experience. To be frank, if you're sick of the bs that is deaing with contractors in DC, go with Mirko. He is not a slick salesman, but a craftsman who will quote a fair price and do superb work. He understands how HVAC systems work, especially in the confines of older homes and how the quirks of old construction might affect the system's operations. Mirko is also an exceptionally decent human being and if you're around while he's doing the work, you may find him to be a "philosopher-craftsman" of sorts. I would highly recommend PCK HVAC for any heating or cooling project. read more

Mirko is definitely the expert to call for your HVAC needs. On a 95-degree day, one of our air conditioning units stopped working. We called Mirko based upon the positive reviews that we found online. He gave us an appointment time for early the next morning, which we greatly appreciated, and he was 15 minutes early! Mirko spent time diagnosing the problem, keeping me apprised throughout the process and physically showing me what was broken in the unit. He explained exactly what he needed to do to fix it and what it would cost. Mirko needed to go and get a specific part, which was quite a distance from our home in Potomac. He again kept me informed via text and returned faster than he had estimated. He also checked out our second unit, provided an honest assessment that it was in good shape, and gave advice on other things that we could do to improve heating and cooling in our home, prompted by my specific questions. Mirko is extremely professional, fair, reliable, and honest. We intend to have Mirko take care of all of our HVAC needs in the future and will recommend him to our friends with complete confidence that they will be delighted too. read more

Mirko has been servicing our aging central air unit for the last several years and has always responded quickly and been very professional and thorough. When the old unit finally died on Friday night, he came out on Saturday to assess. By Sunday afternoon, he was taking out the old unit. And on Monday, he installed the new system. I couldn't be more thankful for the speed of the work, or more impressed with the quality! I would recommend Mirko highly for any HVAC need! read more

Mirko is not going to waste your time or money. He knows HVAC inside and out and works to find solutions that are in your best interest. As an example, Mirko discovered that in our newly purchased home we have two air-handling units (one of which is handmade) running off a single condenser unit, something our inspector didn't catch. While an odd configuration and not ideal, the units were appropriately cooling their designated areas. Mirko suggested we monitor the cooling effects, noting any changes or issues, and he would do the same during his maintenance checks. Together we would decide what, if any, course of action to take. These units continues to operate just fine but when a third unit started to leak, we called Mirko. Only after thoroughly evaluating the unit and options we decided it was best to replace the unit and we hired Mirko to do so. The installation was done professionally, quickly and reasonably. Mirko is extremely reliable, trustworthy, and he really knows his stuff! We have now sought his services mulitple times for various issues and projects and will continue to do so. We hire him with complete confidence and you can too. read more

Mirko of PCK HVAC does a great job at a reasonable price. His estimate to repair my boiler was about half what a larger well-known HVAC company wanted, and Mirko used higher quality parts. PCK HVAC has also installed a new split system in my basement. The price was reasonable and the quality of work was excellent. The technician even took the care to route the condensation line into an existing drain pipe when I expressed concern about water pooling and leaking into the basement. I highly recommend this company. read more

I've been using Mirko for 5 years to take care of the heating/cooling and a few other things in my house. He is professional, honest, always on time, and very competitively priced. Hands down the best you could wish for. He comes on a moments notice, even if it is after hours to fix things. read more

Mirko, owner of PCK HCAV, has been servicing my air conditioning and heating systems for approximately 5 years. In that time, he replaced my old air conditioning compressors as well as changed out my thermostats for digital ones. He does annual checks of my systems. I have found him to be totally reliable, super well informed, and reasonably priced. He is very responsive to emergency situations. He comes when he says he is going to come and does the work thoroughly. It is not unusual for him to work on the weekends to best serve our work schedules. He is now doing the maintenance for a number of houses on our block. I highly recommend this company for service. read more

Had a great experience with Mirkos. Our AC broke and he returned my call within the hour and came to fix our AC the same (hot) day. He was on time and explained everything to me as he diagnosed and fixed the problem. I had him look at another few issues and he gave advice and we definitely plan on using him again. Really great, affordable service. Highly recommend. read more

My experience with Mirko mirrors that of others who have posted on Yelp. Simply excellent. He installed a new furnace and hot water heater for us. An old house, corroding pipes, inconvenient space. But Mirko made it all work and exactly within the very reasonable estimate that he provided in advance. He's quite obviously a master at his craft, extremely knowledgeable, a creative problem solver who takes enormous and justified pride in the superb work that he does. From my initial call for help, Mirko was extremely responsive throughout the entire process. He always showed up exactly when he said he would, worked continuously for hours on end until the job was finished, communicated exactly what he was doing and why, and went out of his way to accommodate our schedule. He exuded honesty, fairness and a total commitment to ensuring his customers are satisfied. I'll never have to look for an HVAC company again. Mirko is a keeper and I'd recommend him without reservation to anyone in need of HVAC services. read more
