110% recommend! Throughout our A/C repair process with them they have been straight-forward, fair, communicated well, and provided top-notch service. We initially brought them in for a 2nd opinion, after being quoted almost $7k for a system replacement, which was recommended as the only solution. Marco came in, quickly gave us a much more thorough diagnosis of our HVAC issues system-wide - explaining how the problems we'd had tied into what he saw and the possible fixes, - a more reasonable solution along with an explanation as to why he recommended one course over the other - age of unit, resale value for home in future, performance, upkeep, etc. - and gave a very fair quote. Work was completed as promised, on time, and above expectations. He was pleasant yet professional, mindful of Covid measures despite the brutal heat, and took the time after to make sure we knew what had been done, what to expect going forward, and next steps to ensure the system is maintained and how he would communicate in the future. If you want an HVAC company that you can trust, these are the guys! read more

I have used Marco & Sons for both HVAC inspection, repair and replacement and in all instances they have provided the BEST service and "product". They are beyond knowledgeable, professional and trustworthy which is unfortunately hard to find in this day and age, and is something that sets them way above the rest in my opinion. I highly recommend them for all your HVAC needs! read more

The owner of Marco and Son did not lie to us, sat down and explained this issue with our current HVAC and offered options. We knew our systems were old and wouldn't last long. He didn't string us along with endless repairs leading to the costly demise and replacement of our system. He told us up front what could and couldn't be repaired and what the outcome and costs would be. He recommended a system (Goodman) and we agreed. The systems (2 separate HVAC) were installed over two days. The crew of technicians were professional, respectful and new what they were doing. We love our HVAC systems! They work well and are more energy and cost-efficient while actually doing the job. read more

As a realtor, property manager and contractor, I use to use Marco exclusively back in the day. His work is v good but his prices are in the Michael and Son and others that spend millions on advertising. His prices just got too high and ridiculous. A water heater that also supplies heat to a condo is about $4200-$4500 to replace. The same unit installed by Marco was quoted at some $6400. read more

I've continued to use Marco and Son since my original review, and they continue to offer fantastic service and an extremely reasonable price. From regular service to emergency calls, from broken water heaters to a full HVAC replacement, they've done a ton for me over the years, and they do a fantastic job each time. These guys are as fair and good as it gets. read more

Overall a good experience replacing our HVAC. We had a few issues post installation, but Marco stood by his company's work and fixed them. If they need to punch a hole in your foundation wall for the coolant lines, ask them in advance to use a drill with a masonry core bit, and not a hammer and cold chisel, particularly if going through cinder block. read more

Requested service, was told that service doesn't include Wv despite the shown range including my address. I told him that he should have his range changed on yelp to not include my address area, ya know so this doesn't happen and waste our time. Mr. Marco then reiterated that service doesn't include Wv and shows the service area clearly showing that indeed my address is still within service area. He is sure I will find a company nearby that will do this type of service which is such a duh no shit sherlock statement that he should be slapped. Happy Holiday and God bless to you. This is me fulfilling what I said about word of mouth. read more

Used for seasonal HVAC check ups at my condo. Very prompt, professional and fairly priced. They were also quickly helpful in a summer heat AC issue. read more

Marco & Sons is the real deal. I initially reached out to get an estimate for replacing my entire central AC system after my condenser unit stopped working--again. Another company had already been out, replaced the contactor, and recommended several expensive fixes. When the unit died a second time, I tried to handle some of the repairs myself (DIY-style), but still no luck. A friend suggested I look into just replacing the condenser motor instead of the whole system, so I contacted Marco & Sons. Marco came out the very next day, motor in hand, ready to go. But after taking a look, he found the real issue--ants had gotten into the contactor I had replaced, and to top it off, I had miswired the capacitor during my DIY attempt. Instead of upselling me or installing unnecessary parts, Marco fixed the actual problem, saving me from replacing a perfectly good unit. His honesty, skill, and quick response saved me thousands--and my AC is running great again. Highly recommend Marco & Sons for anyone looking for trustworthy, knowledgeable, and no-nonsense service. They've earned a customer for life! read more

Marco and his team are amazing! I needed the water heater replaced right away and they responded quickly and did a wonderful job. They're professional and efficient. Highly recommend. read more

Marco is a rare breed - honesty is the name of the game with him. Yesterday I had trouble with my furnace leaking a gas scent; within a week Marco diagnosed the issue to a simple fan speed adjustment, and tempered with the gas valve which fixed the problem. Other contractors would've immediately jumped to replacing the heat exchanger and/or valve. Folks like Marco do not come often in this industry - his work is solid, reliable, honest and excellent pricing and it's why I've been a loyal customer since 2009. FYI - it's his birthday today too - Happy Birthday and enjoy! read more

Worse fucking service call ever. Extremely unprofessional. Technician Richard forgets his tools several times and had to walk back and forth to his truck. He begins to get frustrated. Technician slams my AC unit and the power supply unit on the wall. Not able to drill screw into the unit, keep forcing and almost moved the condenser by force. Starts yelling at me (the customer) out of no where for asking if he can provide another strap to secure the cables. This is the third time I call these guy to fix HVAC issues. Will never call these guys again. PS. Marco himself was amazing, but his employee is total trash. read more

Marco & Son Ac & Heating - tried to force in a screw where no screw hold exist. - Heating & Air Conditioning/HVAC Near Me - Herndon, Virginia

ac was not cooling and called up Marco based on the good review and proximity...he's able to send a great tech out next day and get the issue fixed. Update: the tech sold me an annual main't plan on site, and confirmed with me solidly that it does include boiler cleaning up and filter change after I questioned serval times. It's about half what others charge, so I bought it but not fully convinced, a bit too good to be true. I later send message on Yelp to Marco to confirm the scope...no response...not feeling right, I called 2 days later, and Marco told me the cleaning up is not in the annual plan, but a separate charge. O.K., that's fine, but the tech should not told me that and I asked specifically several times! Marco agreed to cancel my purchase and refund me. so I am still upheld the good rating and hope things get corrected. read more

Husband had 5 different companies come over before deciding to go with Marco & Sons. Provided a fair assessment and replaced our AC unit quickly. read more

Quick, complete, & professional service. Highly recommend Marco for your HVAC needs. Reasonably priced & my AC was back in full operational order on same day! read more

Awesome communication, great service. I just had Marco complete a repair on my AC unit. I called on Sunday, we scheduled for Monday with a 3 hour window. Upon scheduling, I received a confirmation text message. Today, a half hour before hand I got the message that he was on the way. Marcos arrived as scheduled and got right to work. Man, diagnostic tools have changed a lot since I last had to have AC service. He had the right tools to diagnose the problem quickly and accurately. Within 30 minutes the problem was diagnosed and resolved. He was able to explain the issue and resolutions in a way that was easy to understand. The systems he uses for contracting/billing were as easy as it gets. I'll be using Marco for all of my (hopefully few) AC needs. read more

Great service. Very nice experience. Marco seemed to be very knowledgeable. They both were very courteous and polite. Got my HVAC checked and ready for winter and for next year. Pricing is very competitive. I was going to do a water boiler inspection but they told me it wasn't necessary, at this time. My AC Unit needed a part replaced so being very honest they have told me that the boiler doesn't red inspection at this time because it looks new, just to alienate the cost of the unforseen part replacement. Very nice of them. I would definitely hire them again. read more

Marco and Son replaced our home's failing HVAC system last month -- excellent service at a very competitive price. Marco came over within a few hours of my call to inspect our failing system and provide an estimate for replacement. He seemed very knowledgeable and went the extra mile to explain the problem and some options for replacement. The price was very competitive with other HVAC companies, especially the annual maintenance plan. He demonstrated professionalism and integrity and saved us thousands of dollars because recommended using a lower capacity system that was better matched to our home's ductwork. We sought estimates from several other companies. Nobody else volunteered that our current system was too oversized for the space, but when I asked them directly, they all agreed that it probably was. Marco saved us money when he could have sold us more than we needed. His crew came over on time for the installation and left no trace inside our outside our home. Great communication throughout -- regular email and text messages. One month on and everything is working great! read more

I bought a Groupon's deal for half the price and it worked very well. Richard came on time. He was professional and respectful of property. He was able to do 24 point inspection of my heating system and offered some insights! Thank you for being a great and reliable company ! I will definitely use your services in the future and recommend to others! read more

Showed up promptly the next day and quickly and accurately diagnosed that my compressor had failed. Mauricio The technician was very professional and wore a face mask and bottles inside the house. They were able to call Lennox and check the warranty and verify it was covered. Would use again and recommend to friends and family. read more

Our buyer opted to go with a credit, so I didn't need to replace the a/c myself. I did want to say here I had a good experience with Marco and Son. I received a call fairly quickly after submitting for a quote. He gave me a bit of info and options over the phone, spelling out what they would do when they came out to inspect. Their rep was very friendly and walked me though what he felt the issue was, and the possible remedies. Their pricing was competitive. If you're in the market for a new A/C, etc I'd give these guys a call! read more

Marco & Son had the most reasonable estimate for replacing our old heat pump, and we already knew that they were dependable. They installed it in one day and Marco came out toward the end to ensure everything was done right and working properly. Straight talk, reasonable prices and great customer service, that's what has sold us on Marco. read more

We needed duct work done for a range hood replacement. Marco promptly responded to Our request for an estimate which was very reasonable. He was extremely responsive to all of our requests and did a fantastic job connecting the internal exhaust duct and external vent. Highly recommend and will definitely use again for any HVAC work. read more

Marco, the owner is incredibly friendly, knowledgeable, honest, and helpful. He helped me diagnose my problem over the phone and saved me a ton of money. I will certainly be going back for all my HVAC needs read more

Marco came out to give us a quote for a new heat pump system. He was knowledgeable, professional, and helpful. If I need HVAC services again, I plan to contact Marco. We didn't end up hiring anyone to replace the system because we were able to resolve the issue another way, but this was a positive experience. read more

Marco is the man! Hands down the best at what he does.. he saved me from paying thousands in fees to fix my issue.

I love supporting privately owned businesses. Marco was very responsive, punctual and fixed our AC. Very patient too. A bit pricey, but what else do we expect in NoVA. read more

I would definitely recommend macro and son. We had a new carrier air-conditioning installed today. Communication was great with Marco and son. The technicians arrived on time. They were very thorough through the install. I thought the price for the install was honest. Very pleased. read more

Update: Work Complete Was able to get the preparations done and Marco came back out with his team. The move went pretty easy from what I can tell (although with the heat I'm sure it was a little harder on them. 'Feels like' temp is at 102 degrees at the time of this writing) The original quote included the cost of rewiring the power to the new location, however since Marco was able to reuse the existing wiring, he was able to pass on the savings to me. TL:DR - Awesome Service, No upselling, Price came in lower than original quote. read more

My hot water heater wasn't working, so I had no heat either. Marco was here the same day that I called him and in about half an hour he fixed the problem, without having to replace any parts. Hopefully I won't need his services anytime again in the near future, but I would definitely recommend Marco and Son to anyone who needs HVAC service or repairs. read more

I found Marco on Groupon, and scheduled a time for him to come out and respond to an issue I was having with my heat pump. Marco quickly diagnosed this problem and fixed the issue (with replacement parts he had in his truck!). I dread the day I will have to replace my HVAC unit, but I know I will be calling him as he is honest and dependable. Side note: I signed up for his service agreement after he came out to diagnose my original problem. I found this service agreement extremely competitive in terms of service and pricing. read more

I reached out to Marco & Son AC & Heating Company based on reviews which noted that Marco was an expert in servicing Heat Pumps. My system is older and even though parts are no longer made for the unit, Marco researched and was able to locate and install universal parts which saved me from having to purchase a completely new HVAC unit. He changed out a bad defrost board, installed a new fan and A WiFi thermostat which I can regulate from my phone. This is very handy as I have a renter and I can confirm at any time and in any place when I travel, that the heating/cooling system is functioning well. I also appreciate how Marco kept me informed of the options available during this process and I felt that I was able to make an informed choice which was best for me and I also received a 10% discount on the new parts. His outstanding knowledge, expertise and customer service were major factors helping me to decide to purchase a very reasonable yearly contract for service along with preferred appointment scheduling. When it comes time to purchase another HVAC system, I feel confident that Marco and Son AC & Heating will assist me in making a great choice. Thanks Marco and Son AC & Heating! read more

Just had my two week check on the heat pump/furnace coil replacement. Everything was working as expected; Marco and his crew did a great job on the installation--I wouldn't hesitate for a minute to recommend his company to anyone. Just check out his reviews! read more

Called them out for an estimate on replacement of gas water heater, gas furnace, and air conditioner. First the AC; they were honest and pointed out that it wouldn't be that much money to replace the evaporator coil on my 4 year old system because it was still under warranty, rather than trying to sell me a new system. Another HVAC company gave me a high price for the evap coil replacement in an attempt to push me towards a full system replacement. I appreciated their honesty. Now for the gas water heater, and the reason they still get a single star. They told me that for an in-place replacement where gas lines are not being moved, there is no need for a permit or an inspection. I've had a few estimates at this point and every other company mentioned needing permit/inspection, so I was skeptical and pressed them on this. They said if they would be adding more than a few feet of pipe they'd need it, but not for a replacement where the location of the water heater wasn't being moved. I called Fairfax County Building Permits number and posed the same question, and they immediately shot that info down. You need a permit for anything having to do with gas. Either Marco & Son wasn't aware of this which makes them incompetent as a contractor doing this kind of work, or they were lying to cut corners/costs. I'm not sure which is worse, but I absolutely wouldn't use them for any work on my home because of this. If there ever were some kind of accident involving the install and a permit/inspection were not done, homeowner's insurance could deny the claim. It's not something to skip out on for the liability reasons alone. read more

Had furnace inspected last Fall 2018. The tech was on-time, professional, and courteous. She explained the issues clearly.

We have had this company do our heating and ac inspections for several years at two different properties. Their technicians are always knowledgeable and give excellent service. When we have had problems with our systems, they have always come quickly and repaired immediately. Our systems are old and they are always able to explain how it works, what it needs and what we should plan for in the future. I could not recommend them more highly. read more

Professional, on time and saved us a lot of money by being honest about work that didn't need to be done. With that kind of integrity we signed up for biannual service and trust Marco to take good care of all of HVAC needs. read more
