Mann-In, Inc

I have had nothing but great experiences with this company. They always show when they say they will, very friendly staff that was more than helpful last time they checked my heater for winter check up and even went out of their way to do a little extra work for me when they weren’t required to. Plan on staying with them for a long.

Came on time. Found the problem in a few mins. Ordered a part for us, came back in a couple of days with the part. Part + labor was a bit steep but what else can you do when you need A/​C in 100 degree weather. We just have to suck it up I guess.
Folks were nice and I’m inclined to do business with them again. Thanks

Always honest service that is reasonable. We have used them for 2yrs now and will continue using them. They have always had the parts on their truck to fix any issue.

I’ve used this company for a few years. They have reasonable prices, they were able to get me an appointment on short notice, their work and equipment comes with warranties, and very prompt. Ron was my service technician and he was efficient with his time, very nice, communicated the problem well, and did a great job. I would definitely recommend this company and would use them again!

We originally worked with Mann-​in 20 years ago as a referral from friends. They did our yearly service checks on our heat pump system, which we were very satisfied with their service. Ten years ago we needed a new system. We spoke with several local companies, and chose Mann-​In due to their price quote and past service we had received. Today we woke to find our heat pump not working and experiencing the coldest temps thus far for the winter. After speaking with them, (on a Friday) we found they were solidly booked and did not have an opening appointment until Monday. They understood our need and they squeezed us in by 3pm the day we called. They took care of our problem and we felt extremely fortunate to know and work with Mann-​In, Inc. we highly recommend Mann-​In, Inc.

I was prepared to be wow’d given all the five star reviews on Unilocal but they were only ok. The gentleman’s English made it hard for me to understand what he was saying. I didn’t feel like he made the best use of the time spent — he adjusted the dampers for me — which would be fine except for the amount of time he took to TALK about it. He looked at the filter I had recently taken out to let me know if I’m taking too long to replace them — again, given that they charge by the hour, he was just slow in how he talked to me and in every action he took. That made me really nervous. Finally he started to DO something — he checked the pressure on the outside unit and did a freon boost. He didn’t really take a good look at anything to let me know what kind of shape my system is in but assured me everything was fine (how could he tell?) except that I had a leak and that it was probably the coil and that would mean I would probably have to replace the system. I really hoped I’d get a technician who could explain things better than he did and who made better use of the time at my home. Oh and I should say, I waited close to two months for this appointment.

So professional and timely! Will use them again and again! They don’t rip you off like other places and they tell you the honest to good truth!

Just replaced my entire HVAC system with the Carrier Infinity. Got 4 separate quotes and decided to go with Mann-​In for several reasons.
1. Price was competitive
2. Took time to understand your needs and genuinely seemed interested in selling you the right system
3. Seemed very knowledgeable
4. No negative ratings on various opinion sites including this site.
Those were the reasons we went with Mann-​In. Now, I will describe our experience with the actual work. The owner came to do final measurements and explained what he was planning to do beforehand. He also recommended some common sense solutions to issues we were having with our old system around clogged pipes that flooded our basement. He recommended adding a pan and raising the furnace on top of the pan and added an automatic shut off in case water reached a certain level. Who knew pipes from water condensation could clog. He did this at no additional charge. Not sure why all HVAC systems do not come with this prevention? Pipes from HVAC clogged at brother’s home as well causing serious damage to his wood floors… so beware.
The crew were very efficient, professional and knowledgeable. It seemed as if they were in and out. Knew exactly what they were doing and didn’t seem to lose a step. The owner stopped by near the end to do final inspection. So, if you are looking for a HVAC contractor, and you do not wish to gamble on several thousand $$$, Mann-​In should be on your short list.

I do not normally take the time to write reviews so trust me that this company is one of a kind. I own 4 homes so I really perform my due diligence by checking reviews on multiple sites, the Better Business Bureau, and by interviewing numerous businesses when looking for trust worthy and fairly priced contractors and repair companies. Prior to finding Mann-​In Air Conditioning and Heating, I thought I had found a good company. Well, read on.
I was ready to have my entire air conditioner replaced in one of my rental units due to another company’s suggestion that it was not worth repairing and who provided an extremely high quote to add some coolant and repair the core bolts outside. In addition to the service call charge, it would be $ 100 to fix the core bolts, and over $ 450 to add the very «scarce» coolant. Then he stated that even after adding the coolant, the AC would only last another year at most and would most likely keep leaking because there is most likely undetectable micro-​leaks too small to detect and repair (not sure how he knew they were there since they were too small to detect). His charge to do this temporary fix was over $ 600 which I almost paid. He of course explained the virtue of a newly installed unit.
To my rescue came Man-​In Air Conditioning and Heating who I found online. I expected the same answer as the first company. Colton was a breath of fresh air and everything about them seemed different than others I had called. You could tell that these people were hard working individuals, down to earth and trust worthy, cared about their job, and highly trained in their field. Colton quietly reviewed the system, used very advanced leak detection equipment which he explained, told me there were no leaks, and deduced that the system was just low on coolant most likely due to the core bolts outside missing rubber rings. He replenished the coolant (no excessive up charge for «scarcity» like the other company), replaced the rubber rings around the bolts at no charge, and said the system was only 9 years old and he did not see any reason to replace it. No sales pitch! He simply fixed my AC for charge of the service call and the cost of the coolant. I trust these people and will use them again for every home that I own, now and in the future.

Easily the best HVAC people in the area.
I have the furnace replaced and new ducts put in the basement. Not only did three different people come in to complete the job in one while other companies quoted a two-​three day job completion date. They also extended a discount from the previous month in order to match the price of their competitor. Stan Lee is awesome as a salesman. He is never pushy, and he wants you to save as much money as possible. I had never had to replace a furnace before, so it was also nice to have somebody walk me through it in more simple language as well.
Two day after the install we replaced our thermostat with a learning one, and it wasn’t reading correctly. We called them up and they came out and fixed it within an hour of calling them for free even though they were not the ones who installed it in the first place.
Customer service and commitment like this just don’t exist around here anymore, and it is nice to find at least one company that knows how important it to treat customers well.

Mann-​In has been a part of the Virginia Run and Pleaseant Valley communities (Centreville) for over 20 years. They’ve serviced my HVAC systems over that time and have never let me down. On the sales side Buck tells it like it is and prices the work fairly. The technicians know their stuff and are courteous and friendly. As a long time customer I highly recommend these guys!

Our full AC and Heat system was replaced by Mann-​In on the day right after Labor Day. Out of the 6 estimates I had, Mann-In’s was competitive and sounded most dependable. Believe or not, a «Technician» from Company A even told me that I am having a Pump system (Called the manufacturer, Carrier, and found it is AC). The contract was detailed enough, including equipment number for AC, furnace, coil, Thermostat unit, and the size of supply trunk to facilitate the air flow required by the equipment (5 tons in my case). Best of all, the company president made an on-​site visit to finalize the work scope and installation specifications before I signed the contract. Three guys worked on the project for approximately 8 hours. The lead technician was patient in explaining to me everything I raised, from simple control unit menu questions to engineering work. I felt that the job was professionally done. I got the promised manufacturer rebate within 4 weeks without any hassle. I waited for nearly a month to write this review and you can tell that everything works great. The lessons I learned through this process were: (1) Do homework and research to get the initial list of companies, including checking manufacturer’s authorized dealer list, Unilocal review score and other comments; (2) Hold decision until when all visits by committed companies are completed and estimates are compared and verified, focusing on price, equipment quality, and potential installation work (better specified in the contract); (3) Review contract carefully before signing especially when several rounds of negotiations and revisions are made. (4) Be cautious if you sign up at Homedepot ‘s website for HVAC services. You never know who is going to show up at your door. Checking manufacturer’s dealer list turns out to be a better and cost-​efficient solution. Overall, I am very happy with my current system, its WIFI-​enabled thermostat control panel, and the overall look of the supply trunk, pipes and furnace in my basement.

As far as HVAC professionals in the Northern VA area these guys and girls are the best!
I had 8 estimates for a full system replacement and they came in very competitive and also really took the time to explain the pros and cons of the systems they recommended.
I cannot say enough great things about the installation process. They arrived on time and worked with German precision, they put drop cloths on EVERYTHING, my closet that has attic access was completely covered with drop cloths and they even protected my DRIVEWAY and yard. Yeah, you read that right… they covered my driveway with a drop cloth!
After the installation they made sure that I understood how the system worked and assured me that if I had any questions I could call and they would come back anytime.

Mann-​In replaced our HVAC a month ago.
Think in terms of Apple versus a PC. Six companies gave estimates. Some came with no explanation. Others tried to sell things we didn’t need.
After going over all the bids, we went with Mann-​In: the salesman was smooth, but explained the options well. A guy came ahead of time to measure and double check what equipment they would need. The installers showed up on time, were super neat and super polite, and finished on time. The foreman of the installation team ensured we understood exactly how the equipment works before he left.
And most importantly, the new HVAC works well, is quieter, and appears to be more efficient.
They’ll get the fifth star in 10 years — if the equipment is still working as well then as it does now.

Had my A/​C die on one of the hottest days of the year. Called Mann-​In and made an appointment for the following day. They came in the time frame they said they would. The technician took a look and said the blower motor had stopped working, but it might be just the solenoid, which would be a lot cheaper. He replaced the solenoid and the motor began working. Then he checked the freon and found it was a bit low, so serviced it. Didn’t try to sell me anything I didn’t need, was fast, professional. Highly recommend.

Well, the old AC finally died, and I decided to replace it with a hybrid energy efficient furnace and heat pump. I interviewed several contractors, and picked Mann-​In. (found Mann-​In from Consumer’s Checkbook.) Mann-​In is a small local firm that has been in business over 27 years. Their staff is extremely competent and professional. They really know what they are doing, and they delivered everything they promised, when they promised it. The quality of the workmanship was excellent. When the county inspector came to look at the final job, he even praised the quality of the work.
