We had used Mann-In for a maintenance program before and were impressed by their professionalism. The Mann-In sales rep was perfectly professional, on time, efficient, and clear about our choices. Unlike a previous provider who took nearly two hours (we compared three different offers), Mann-In's rep spent a reasonable amount of time assessing what we had, took measurements and gave us an estimate later on the same day. Their price was actually a little bit lower than our final choice. We deliberated our three choices carefully and probably would have chosen Mann-In, if it hadn't been for a three-year 0% financing offer from their competitor. Unfortunately, Mann-In was only able to offer us this option for one year. Considering the $10,000 price tag, this was an important factor.
Description of Work: We asked Mann-In for a quote on a new HVAC system. They did a very thorough assessment and gave a detailed, transparent description of the equipment choices.

Our natural gas conversion experience with Mann-In was great. Buck Bradley was our point-of-contact and Mark was the team lead on installation day. I'm not that great of a writer, but there's a few other good reviews here (review date of: Jan 30, 2015 and Jan 4, 2015) with experiences very similar to ours. A note for those also looking to convert to natural gas: we initially contacted Mann-In in February, signed our paperwork agreements & paid down-payment in May - and it wasn't until October that Washington Gas was able to come out and install the gas line from the street to our house. Mann-In then came in at the end of October to complete the appliance installation. So start the process way in advance of when you want to have natural gas running live at your house.
Description of Work: Natural gas conversion. Brought gas into our single-family house, replaced existing electric heat pump and water heater with gas furnace, water heater, and A/C. Also installed gas piping, humidifier, and new thermostat controller.

We decided to partner with Mann-In for our gas conversion and we could not have chosen a better more reliable company. Buck Bradley met with us in early July to review our wishlist of appliances to convert and then he came up with a plan to make it happen. There are a lot of details to consider when it comes to running the gas lines and how to run the pipes with the appropriate slope and Buck spent many hours at our house coming up with a workable solution. We appreciated the attention to detail and he even called two other gentlemen that worked at the company to come by the house to ensure everything was doable. Because we started this process in July we didn't refill our oil tank assuming everything would be in place by the time the cold weather hit. Unfortunately, working with Washington Gas was a nightmare because they were slow in processing all the necessary paperwork so we were without heat in October and November. To make matters worse we had a newborn and wanted a warm house for our new little girl! When we brought this to Mann-In's attention they went out of their way to bring us enough oil to tide us over until Washington Gas could confirm an installation date. Once the gas line was finally installed, Mann-In rearranged their schedules to get our furnace up and running immediately. I have NEVER worked with a company that cared so much about their customers. I cannot say enough good things about their customer service, attention to detail, and overall professionalism. My husband and I have worked with a lot of contractors over the last two years and Mann-In by far provided the best experience.
Description of Work: Assisted with gas conversion process. Installed lines for a new furnace, water heater and cook top.

After a spectacularly bad experience with another vendor, we were referred to Mann-Inn from a colleague who lives in the neighborhood. They came the next morning, and were able to get a replacement part sooner than promised. The technician was courteous and professional and was able to get our heater working within a couple hours of showing up with the replacement part. I've never been so relieved to deal with a company and technician who were simply honest and competent. We will definitely call them next time we need service on our heater.

In case there's an issue, they will not charge me labor per the agreement, as long as I pay market price for the parts. Last year I found a coil broken. They explained that I would have to pay $1000 for the coil alone. They force their customers to buy high priced items to cover the "free labor."

This fall Mann-In performed a natural gas conversion and replacement of our entire HVAC system. I was extremely pleased with the entire experience with Mann-In and all of their employees. The sales associate, Buck, was very thorough in his discussions regarding the possibilities of replacing the various components of our HVAC system (high-efficiency furnace, hybrid options, keep existing humidifier or replace, etc.) and the necessary installation of natural gas lines. Their staff also helped me to navigate the frustrating bureaucracy of Washington Gas helping to speed the process along. The installation of the natural gas lines and HVAC system went very well as Mark?s team worked with the care as if they were in their own home. I appreciated that at the end of walking through how to use the system Mark, the lead installer, reiterated that I should not hesitate to call with any further questions and their team would be more than willing to help. This further reiterated the dedication of the Mann-In corporation and all of its team members to the work they perform and the customers they serve. I would strongly recommend using Mann-In again and intend to use them in the future for additional work.

We were very impressed by Mann-In from start to finish! They provided excellent and professional service with an emphasis on customer satisfaction. The sales person was punctual and knowledgeable, and gave us a very competitive estimate with all available rebates for the different units we were considering, as well as a good warranty. On the day of installation, the technicians were punctual, professional, efficient, and knowledgeable. We were especially impressed that the owner of the company came out and reconfigured our air handler ducts to help them work more efficiently. We felt like everyone was working to provide the best customer service, and they did it at a reasonable price. I would highly recommend this company!!

He was on time and it was an "emergency" because our A/C wasn't working upstairs and it was like 105 degrees outside that week. He confirmed we had a leak... we had to have A/C repairmen come out each summer since I moved in 3 years prior to add coolant to our apparently leaky A/C unit which was costing us a bundle if you added it all up. The Mann-In guy explained he would refill the coolant for a nominal fee and he would give us an estimate to replace the unit. But he recommended we should wait a bit and see what happens. That was June of 2013. So summer 2014 I was expecting to have to call them out again to refill the coolant... only I didn't have to. Our A/C unit worked wonderfully all summer long two years in a row. They saved me money and that means they have earned a new customer for life. Thanks Mann-In! I am calling them to give me a free estimate for installing our home humidifier now.

I have been an A #1 fan of this company for YEARS- a loyal customer through two homes. I have been using them exclusively and referring them to anyone who may ask for the past six+ years. Today I had scheduled a regular maintenance appt. for my furnace like I do TWICE a year. The window was 12-4, so I took 1/2 day off of work and to make it worse, I rescheduled a real estate closing specifically around this appt (making it an evening closing- not super convenient). After sitting for two hours, I randomly check my home voicemail for other messages, and there's a message from Jody saying she's got "a lot of no-heat calls and is down one service tech" .... I'm slightly annoyed because I specifically gave them my cell phone to use, but called her back and tell her I've taken half a day off and scheduled a bank closing around this appt., I really need to keep it. I'm greatly sympathetic to the people who have no furnace, but I must admit, I've waited longer then a same day appt. in those same situations before, and it seems to me the scheduled appts. should take precedence unless someone is willing to reschedule. She says, and I quote, "The only way that's going to happen is if I cancel someone's appt. with no heat." So I ask when it can be rescheduled, as I can't take half days off work easily, and she says, "That's the thing, I don't even know exactly because I'm down one tech and I'd have to call you back with a date and time. I'd be willing to work around your schedule, but I don't know when it will be." I explain I'll just go with someone else "which I hate to do as I've been a loyal customer for many many years...." and her response? "Yeah. Okay, Sorry about that." So much for customer loyalty. We used this company to install a full HVAC system previously, top of the line, nearly 10K - and have used them religiously for service ever since- even after moving into another home across town. I completely understand the issue with same day appts., but I am fairly sure other companies work through the night on those emergency appts. and don't leave their regular customers behind to do so. Thanks for costing ME money today, and giving us nothing in return- I sure wish I could have those referrals back. Never again. I'm so disappointed.
Description of Work: After being a regular customer for many many years, stood us up with little to no concern, for an appt. scheduled for today.

From beginning to end, an amazing experience! After an initial call to schedule an estimate, the company's representative arrived on time and provided a detailed estimate and explanation of the procedures that would be performed. Following that, calls explaining the finer details and scheduling options were both professional and informative, never leaving me in doubt as to when or what would happen next. But what put them above all other contracts who do this work, in my opinion, was the speed they took in scheduling a "temporary" unit for me to use while waiting the 3 weeks for installation - truly saved me this summer! And when the day came for installation, the crew arrived early and prepared, finishing the entire job with an hour to spare. Truly, it doesn't get any better than this.

After speaking to the provider I realized I was going to have to do this project through my home warranty company first. I contacted Angie's List in order to get a refund of the Big Deal purchase.
