We have a maintenance contract for the year. They are very good. I think they have a good price. I have been with them for, probably, at least 15 years.

Excellent, as always. Over the last 5 years they have supplied a complete replacement HVAC system (Carrier), substantially replaced our attic HVAC supply line insulation, did the rough-in HVAC supply line work for a basement finishing project and supplied a replacement hot water heater. They accomplished all work in a timely manner and clearly demonstrated superior quality of equipment and materials as well as superb workmanship. Their careful attention to detail and precision is far above today's norm. Highest recommendation without reservation.

They were the only people who, when I described how hot it was upstairs, figured out a way to do dome heating and air conditioning. Everyone else who came in with the unit said they would put it in our place and tell me the extra stuff they needed to do to have it worked so they were great. The cost was higher but I got more from them than I did the other quote. They did more. They did the zoning and all that work so I thought it was completely justifiable. I can't compare them to the other quotes I got because the other people quoted 3 things and they quoted 8 things, and so they had more work scope so it cost more, but it was justifiable. The humidity was high and I called them and they sent a guy out twice in the last week because they put in an individual dehumidifier and they got the humidity down where it needs to be, and then the system was taken over. They have been creative and very, very customer service oriented. They were right on time. They said they would be there at 8 o'clock on a Thursday and they were. They said it would take 2 days and it did. Everything is efficient. I was asking for a lot of quotes. I asked a lot of questions and they explained things. Before I picked them, I did a lot of back and forth with them and the other people who gave me quotes, asking a lot of questions. They were very professional. I have already recommended them to 2 other people and somebody else is getting a quote from them right now.
Description of Work: I just had a new heating and air conditioning system put in by Mann-In Inc A/C & Heating. It was a complete system with the air conditioning, furnace, humidifier, and controllable-through-a-smartphone thermostat.

These guys are as good as it gets. First class. Carrier Presidential Award. Workmanship, equipment quality, are absolutely flawless. Owner typically does the estimates and he is no pressure. Company installs water heaters, HVAC. Pricing--very fair. You generally cannot hear the equipment running except the outside unit which is also very quiet (about the same loudness as a conversation). Our house is quiet, comfortable with even temperature on all three floors (within one degree) even though we only have one large unit. Owner came out and personally inspected every inch of the jobs. Another owner came to measure sheet metal. Installed extra return air ducts, reason given "it should have been there to begin with and will help the system work better". Water heater had expansion tank installed, reason given: "we do it on all of our water heater jobs, it is better for the tank and helps the water heater last longer". Company used tin plated evaporator coils rather than standard evaporator coils, reason given "more durable, higher quality, less chance of leaks". With the fresh air intake, drywall had to be cut in the ceiling--there was not one speck of drywall dust, dirt or any debris anywhere throughout the house. Cleanup work--looked better than when they started. Used drop cloths everywhere--even in the driveway. Personnel are extremely polite, hard working, well trained and wear shoe covers. Permits were pulled from Fairfax county. County came out and inspected the work and said--I am going to look at everything sir, but, Mann-in did the job, I have never had to call them to re-do something not in the 20 years I have worked for the county.
Description of Work: Total HVAC system replacement with super high efficiency Carrier Hybrid heat system (infinity gas furnace and 2 speed heat pump), large fan powered whole house humidifier, fresh outdoor air intake, carrier infinity air purifier and UV lights. Installed natural gas line for dryer. Another home--two carrier infinity hybrid heat systems, as above, installation of 75 gallon gas water heater.

Mann-In is awesome! I used them 7 years ago to install a new AC and heating system. They were great to work with, gave me a good deal, and helped me get additional rebates. The installation went smoothly and the system worked great. This summer, the outside unit went out (fun fact, dog urine is very bad for condenser coils). After trying to work with a different company (because they had a deal going), I called Mann-In back. They responded quickly, helped find an affordable solution, and my AC was back up and running fast! I will continue to work with them!

After the technician left I never heard back from the company, so I called Mann-in and spoke to Jody their service manager. She was very matter of fact about the delay and not apologetic at all. She promised to have the owner Chuck get in touch with me. 3 more days have passed and I haven't received a call nor a written opinion/quote. I called again to follow-up and was put in touch with Chuck (the owner) who was rude, unapologetic and dismissive. He said that I shouldn't expect to receive anything from them before another week and a half and said good-bye. I asked him if he could allow me to finish before he hung up and if they could send me the quote sooner as the weather would be changing soon leaving little time for a solution to be implemented. I also told him I would have expected a quote in a day or 2 after the visit like most other HVAC companies specially since I had paid $130 for the visit and received nothing for it. Chuck then rudely told me I could expect anything but they would provide the quote when they wanted to. I'm still in shock at how an owner of a business can be so disrespectful and rude to customers despite having charged them for nothing in return. I would not recommend this company to anyone as I found them to be very unprofessional and just in it for the money not customer satisfaction. I'm a year out from purchasing a new system and am also currently evaluating HVAC companies for my future purchase, but will certainly not be considering Mann-In.
Description of Work: I called the company and informed them that my HVAC ducts had to be evaluated for insulation. I also informed Mann-In before they sent someone and charged me $130 they needed to make sure a duct insulation specialist was coming out as I had already had another company evaluate the situation and was looking for a 2nd opinion. Mann-in sent a HVAC service technician who wasn't from the insulation department. He assessed the situation, charged me $130 and left saying Mann-In would send me the price for the ducts to be insulated and I received nothing from them afterwards.

Colt came out on time, the office e-mailed me a heads-up to let me know that he was enroute. He checked the refrigerant (non needed) and went on to discover that the capacitor was blown. This is fortunately a stock item on his truck. He swapped it out and we were back in action. My units needed a good cleaning (my fault). My vent filters are always checked. Two hours later and the house is almost there. $130.00 - service call $110.00 - part $240.00 Grand Total One always wishes to pay less, I just want it fixed. It will be 96 degrees today. Thanks to Colt and Mann-In.

We have a contract with them. They come out in spring to get us ready for the summer and in the fall to get us ready for the winter. If we have a problem they will come immediately and that is another feature of the contract. We have been happy with them, this has gone back years and years.

Russell Bradley provided second inspection and estimate after another company advised our AC was in need of replacement. After presenting us with our options and the corresponding estimates, we decided to use Mann In. Mann was not the cheapest nor the most expensive, but we have used Mann On prior occassions for servicing. After entering the contract, one of the co owners came to take measurements and offered to refill our freon free of charge to "carry us through the hot days" before the installation date. (Bradley also provided the same offer during intial discusions). A date for installation was set. On the day of the installation, Mark, Dan and their assistants showed up on time as promised. They provided a detailed description of the work and provided a estimated time of completion. No issues w the installation. They were efficient and professional during the entire process and finished 2 hours earlier than estimated. I highly recommend them.

Mann-In does a very professional job. Unlike many others, they focus on the job at hand. They do not spend the visit trying to "up-sell" you to other services. I have recommended them to others and I will continue to do so. I have searched long and hard for a vendor who focuses on the work and I am very happy with Mann-In.
Description of Work: Mann-In provides preventative maintenance to our home HVAC system. We have two zones. They provide fall and spring checks as part of the maintenance agreement.

I used Mann-In to replace my builder grade POS HVAC system with a new super high efficiency Carrier Infinity Hybrid heat system with humidifier, Infinity air purifier and ultraviolet lights. The quality of work and attention to detail was incredible. Even better, my home could not be more comfortable, the system more quiet nor could we be happier with our new system. Mann-In Owners Ron and Chuck are straight shooters, are honest and fair, their pricing is very reasonable and they stand behind their work 100 percent. Another plus--they don't try and sell you something you don't need or don't want. I recommended Mann In to my neighbor who replaced his system with Mann in and my parents who replaced two systems and a water heater with Mann In. Look no further. This is your new HVAC company. Kudos to the Mann In team for years of excellent service. thanks, Ken Little/Laura Pierce

I called Mann-In on October 9th to schedule an annual AC/Heating service checkup because they originally installed my /AC/heating system. I was told they had no openings until December 4th. I tried to get an earlier appointment, but was told they are on first come, first serve basis. So, I agreed to the December 4th appointment date. I was told the appointment would probably take only the minimum 30 minute charge. On December 4th, the service tech arrived on time and checked the heating unit in approximately 10-15 minutes. He said all was fine, but he couldn't check the A/C unit because it was too cold outside - 46 degrees F. Thus, I received only half the service I was being charged for. I called the Mann-In office and was basically told I was out of luck since it was too cold to check the A/C unit and there would be no adjustment in fee. It needed to be at least 60 degrees F to do an A/C check. I was NOT told this when I made the appointment in October. Thus, I would not recommend Mann-In for doing annual heating/AC checkups.

The work went very well. The technician knew exactly what he was doing, was very professional and courteous. And what was an added pleasant surprise was the cost came in lower than what they originally quoted. Nowadays, it very difficult to find a company like Mann-In - one that you can really trust and performs an outstanding job. I actually started with another vendor for the diagnosis, but really wish I went to Mann-In first. The other vendor didn't seem to know what he was doing and went through a lot of trial and error to figure out the problem. They later gave me a quote that seemed rather high based on what I knew of the repair process. I then contacted Mann-In, based on a friend's referral, and they provided a truly honest and much better price. Although I was out the diagnosis fee from the first vendor, I still saved overall and feel confident Mann-In did a better job than the other vendor would have done. I highly recommend Mann-In. Jodi, the service manager, is terrific.

Mann-In did an excellent job replacing my hot water heater. It started off with an issue where the drain pan was to big to fit in the space where the hot water heater goes. This is particularly important as it is located in our living area, not in a garage or basement. Even a small leak could cause big problems. This guys doing the work immediately figured out a solution and implemented it to my satisfaction. Just as important, I was at work at the time and they treated my wife with total respect and were very professional.

Mann-in gave me a very competitive offer on a quality unit and their sales staff was professional--no pressure sales tactics. Since our AC wasn't working at all, they came four days after I accepted their offer, 3 if you don't count Sunday--very responsive. This was an expensive install, and the work quality exceeded my expectations. The technicians arrived on time, were professional and friendly, even took their shoes off to come inside the house. The technicians were detail-oriented, all the ductwork was very well done, quality craftsmanship on the whole installation. Mann-in gave us a one year warranty and 0% financing. A month has passed and the AC is cooling great. Highly recommend these guys!

We had previously used another company to service our furnace for 10+ years, and were looking for a change. They had indicated that a furnace gas valve was faulty and it would cost $510 to fix. We had heard good feedback from friends that had used Mann-in, so we throught we would give them a try and get them to give us a second opinion.. The Mann-in representative was respectful and confirmed that a gas valve was not operable, and would cost $187 to fix. Since our system was already old, and we had done some previous repairs, we chose to replace our furnace and A/C systems. We got 3 quotes, and Mann-in was $1000 less than the closest competitor. In our experience, Mann-in is on-time, courteous, they do great work, and they charge reasonable prices. Definitely recommend them.
Description of Work: Mann-in serviced our furnace, which was 15 years old at the time.
