The techs were on time, courteous, and knowledgeable of the system. The lead tech confirmed my suspicion that my builder's subcontractors were not familiar with the proper installation and adjustment of the Carrier Infinity HVAC system - which is why they improperly installed an extra humidistat for my humidifier (causing the humidifier to stop operating in the second year), and failed to adjust my system for most efficient operation. They fixed the humidifier problem quickly (removed the redundant humidistat, adjusted the humidifier for proper installation) and checked over the rest of the system, adjusting inefficiencies where they found them. They did not pressure me to sign a service contract or to buy any other products. Their quality can be attested to by their recent selection by my builder (Winchester Homes) as their HVAC warranty maintenance subcontractor.
Description of Work: Corrected a improperly-installed (by builder's HVAC subcontractor) humidifier by removing a redundant (and malfunctioning) humidistat. Adjusted the humidifier and the Carrier Infinity HVAC system settings for better efficiency (the builder's HVAC subcontractor had left them at the default settings). Performed a standard full-system check and confirmed proper operation of the system.

Great. We will call them again in the future. They were quick to come out which was greatly appreciated. The gentleman was professional and got the job done quickly. We like the fact he educated us as well.
Description of Work: Our a/c wasn't blowing cold. I call around Monday and I couldn't get an appt. anywhere till Wed. or Thurs. I got a return call on morning - Tues. from Mann-In whom I left a message for after hours, and it was around 8:30am to have the a/c serviced at 10am! Yes, they gave me a time...no window of time! He showed up and within a half hour we were as cool as a cucumber! Yea! Thank you Mann-in, Inc. for the speedy service. It was a minor part to be replaced and we were good to go. He did advise us the heat pump need to be replaced in 3-5yrs which as nice to know so we can plan financially for the replacement. Also my hubby is severely allergic to mold so he warned us the boxes in the attic look like they have mold on them would could come into the house through the vents.

They were fantastic. The person that came took a great deal of time to talk to us and answer our questions and educate us during the initial estimate call. He explained things in simple terms and did not rush us through. Their price was as competitive as any of the three companies we had contacted. Not only did they give us an HVAC system but also reworked the duct work and made our system more efficient. They said they could help our house cool better. They also ended up replacing our hot water heater. I can’t say enough good things about them. The team that came in on that day was on time and was clean. They finished quickly and answered all our questions. They educated us and made follow-up calls to make sure that we were pleased with their service. They were great. I will definitely use them again.

We contacted them for an estimate. They came on within a few days. Along with the estimate, they did a pitch for a new system. (ours is old, it works fine, and everyone tries to sell us a new one.) They then followed up later, to see if we wanted to do the work. We discussed it and agreed, and then they scheduled it and came out and did the work. Overall, they did good work, but the reason we would hesitate to use them again are a few. First, after I had spoken with Ron, the gentleman from the company that came and gave us the estimate, and I agreed to go ahead with the work, the next day, someone else (possibly named Dan?) called me and asked me if I had decided to go ahead with the work. This was really odd, and it seems they have some communication issues at their company. He should know we already agreed to the work, and not be confusing customers. Secondly, they did not provide us a time when the technician would come and do the work on the designated day. And, to add to that, the technician called and asked for our address. This was after the company had been out for an estimate, and we had already given them our address. Again, some serious communication issues need to be addressed here. They shouldn't need to ask us for an address that they already have. And finally, we were told that the work would take about 2 hours. The work took only one hour, so we feel that the price was a bit high for the time and small amout of labor involved in adding the return vent. This is why in general, we will not fail to consider other companies for future HVAC work. They were good, but they did not hold our confidence.
Description of Work: The added a return duct in the basement, to the HVAC system. This had been mentioned to us several times by other contractors as a way to help with A/C costs in the summer. Previously, we only had return vents on the top 2 levels of the home. The technician cut a hole in the wall from the room adjacent to the HVAC, put in a flexible tube, cut a hole in the HVAC to attach the tube to, and then patched up everything and put on a white grill vent.

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. A couple gave estimates without even coming out to the house. 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. We went with a variable speed, high efficiency model. It is quieter, more comfortable (the A/C dehumidifies), and appears to be more efficient. Here's the problem as with most major home repairs: I won't know for at least five years how good this equipment is. Note: the price is after rebates.

They were very professional. They were very competent and spent over 2 hours when they were explaining what they would do for us. They looked good and the things they hadn't out were very informative. The gentlemen were always on time, as they promised. The gentleman we worked with was very competent. They took all the time in the world to explain it like we were the only people on the planet. Our A/C exploded, so then they came in and had everything set up and ready to do the job once we got back from our trip and they were very flexible with the schedule because of our traveling situation. They did the work all day, left it very tidy. They explained the thermostat and also gave us an upgrade on the original one we bought because it wasn't available. They also did some additional duct work at no extra charge. There were a lot of rebates that we will be able to get back. They made sure that we registered online with the state of Virginia for the rebate. I had complete faith in them to get the job done. It was just all around very professional and completely positive. I would definitely recommend them to others.

They seemed to be very involved in the work. They came out when we requested. They spent a lot of time with us talking about different features. One thing I remember is that they did not try to sell us the highest or greatest thing. He actually told us that the middle of the line unit was best for our house because we only have 2100 square feet house. It was very nice. He was very honest with us. I have already recommended them to my neighbors also to use their service. They have a good customer service and they followed up too. They called and asked us how everything was going. They are actually trying to set it like a service check with us since it has been a year. I was very pleased with them. The price was average. Quality was excellent. They are very responsive. I would use their service in the future too.

Like I told the owner, Chuck, 5 STARS....and more. Mann-In does outstanding work. From start to finish these guys are professional. These guys work like clockwork. You have my business. I know who I'll be calling when my second system needs to be replaced. THANKS Chuck, Drew, Cindy, Mark, and all.
Description of Work: I replaced one of my two split AC/furnace systems in Great Fall, VA. My upper level unit was 10 years old, and my "other" HVAC service company cautioned me about a costly coolant leak. So, after researching and obtaining 4 price proposals, I decided to go with Mann-In based on A+ reviews, professionalism, professionally prepared proposal, sales person's knowledge and responsiveness, and pricing. I decided to go with a 80% AFUE Carrier furnace and upgraded to an Infinity AC, Controller, and Aprilair 2210 medial air filter. You would not believe how much quitter the new high efficiency two stage systems are. I am hoping to save some big $$$$ with the SEER 18. I use propane for heating. Maybe someday I'll get natural gas up my street. The salesman, Drew, made sure all my choices complied with the Federal Energy Tax Credit guidelines. In my situation, with a SEER 10, I had to upgrade my furnace and coil to comply with the minimum SEER 16 requirement. The salesperson was very helpful bringing me up to speed with the different solutions, components, energy terms, and making sure I knew about the second launch of the Virginia Energy Efficient Tax Rebate. Thanks Drew. The day before installation, Chuck Brown (the principal) himself came out to measure the entire project. Just like the salesperson stated. He was not kidding. How refreshing. One of the biggest Carrier dealers in our region has principles who know what their doing. So, Mr. Brown measured everything including: attic entrance, pan, space for new unit, the flu, condition of duct work, and general access. This certainly helped insuring things worked like clockwork the next day. Mann-In even corrected a number of issues with the original duct work. Probably one of the BEST contractor experiences I have ever had. The next day, the project manager came by. The entire crew came in and started by laying down tarps on all floors. Amazing. Nothing damaged or left behind. I could hardly tell anyone was around after installation. No screws, sheet metal, tools, boxes, or other trash left behind. I was so comfortable with Mann-In, that I went about with my errands and left the house in the hands of the project manager. I strongly recommend Mann-In for your heating and cooling requirements. These guys are very customer facing and knowledgeable. 5 STARS.

The sales pitch - Mann-In provided excellent information during the quote process. Later they matched another contractors price on some specific components. They also credited us $126 spent on a service call the previous month. The information provided was thorough and the salesman knew his and his competitors products well. I checked around on price, features and options - everything checked out and was competitive. The install - We had experienced multiple snow storms with over 20 inches on the ground in the Wash DC metro area. We had concerns Mann-In would reschedule, but they arrived as scheduled. For the outside unit it only took them a few minutes to dig a path 25-30 feet through 2 feet of snow to the old compressor. Indoors they put down tarps from the front door all the way down to the basement utility room to keep things clean. They started around 9 AM and were done by about 1 PM. One of the technicians explained all the features of the air handler and humidifier, then explained the sophisticated Infinity thermostat. These guys did what they said they would do, even in 20+ inches of snow. They got things done in a timely manner, they were polite and professional, they encouraged us to contact them free of charge during the warranty period if there are any issues at all. So far the unit is running great, the heat works great. The new compressor is a 2 stage reciprocating piston model. I was concerned it would be loud, but it's quieter than the old unit and barely noticeable from the sidewalk (25-30 feet). It will take another year to know how well the AC works and how much we're saving with this more efficient system.

I got several quotes to replace old poorly functioning heating system. The estimator, Buck Bradley, was by far the most professional, carefully explaining the system he proposed, it's benefits, and the installation process. I was very pleasantly surprised to learn they would be able to install the system within one week. Today, the crew arrived right on time and in only four hours they had installed a shiny new furnace and heat pump. The installer Colt did a great job explaining how the system works, troubleshooting, and how to use the thermostat. The owner Chuck Brown even came over to make sure everything was going okay. Everyone at the company was thoroughly professional. Gold standard service. I am impressed.

The workman arrived within the time period specified. He serviced the unit to ensure it would be safe to run during the winter. I moved into this house in February 2008, and the unit had not been serviced in a while. He replaced the filter and cleaned the gunk that had built up in the duct. The unit includes a non-operational humidifier; he was upfront about the cost to repair this unit and did not pressure me into making the repair that day. I'll be scheduling a summer tune-up with this same company sometime this spring.

The salesman presented six options, plus three add-ons and explained the benefits of each. Within a couple of days of making my selection, the owner took the measurements and explained what the workmen would be doing and how they could improve my a/c, heat pump, and existing oil furnace configuration. A date was set for installation, a crew of 4 arrived on time, and I was very satisfied with the work. My only request was that they redirect a drain pipe so it was out of the way. They took care of it promptly. They explained the new thermostat and offered to return if I had any problems.

I cannot recommend this company highly enough. When our system went down, we knew we were going to be in for a significant investment, so we took the time to get several estimates and educate ourselves on the options so we didn't feel so "educationally disadvantaged" when the estimates started coming in. From the estimate (Thanks Mr. Gardner) to the time the owner took to come measure personally and really listen to what we needed and changes we were hoping to make, to the installation crew (Thanks, Colt- and the rest of the crew!), this company was EXCEPTIONAL. Seriously, it stinks to have to spend that much money on something not so fun, but this experience was A+++ b/c of the professional and knowledgeable employees within the entire company (Thanks, Cindy!) The financial piece was a value as well thanks to their attentiveness to what we wanted as well as letting us know of many options and rebates being offered by Carrier. I will never use another HVAC company again- EVER. On time- super clean- totally not creepy (females will get what I mean!) - JUST EXCEPTIONAL.

It went well. We were really impressed with the guy who came out to give the estimate. He was very patient and knowledgeable. They honored the original estimate. There was a little confusion on how the duct work would go in but they figured it out and made it even better. They were efficient and did a really good job. We had five different estimates and their's was the most informative and they came up with the best plan for installing duct work.
