After more than three years of annual contracts with Mann-in, I am convinced that they care little about customer satisfaction. Mann-in is a terrible company to do business with. There are plenty of good heating and air conditioning companies out there but Mann-in isn't one of them in my opinion.

We have been customers for 10 years! Without a doubt, they are the best HVAC contractors around. We bought a new Carrier system from them over a decade ago and via great service techs and a great product, they have kept our AC/heat running smoothly. The techs are highly qualified, courteous, trustworthy, professional. Jodie keeps things running from the office and is a pleasure to work with. If there was such a thing as a 10 star rating, this company would get 15 from us! Look no further.
Description of Work: Routine service. Maintainance contract which is worth every penny.

Phenomenal, can't recommend these people enough. From start to finish everyone from the office staff to the sales rep to the installers were a breeze to work with, friendly, professional, and punctual. Replaced an existing Trane system with a top of line Carrier system for $2000 less than the next best competing estimate, just got the first electric bill and it's already saving us money. Great job Mann-In!

I cannot say enough positive things about Mann-in. I called on a Saturday, after a gas leak at our meter, to have someone check out our 25-year-old furnace. Dan came out to look at the system just to be sure our family was safe, and offered some great advice. We had a new system installed first thing Monday morning. Mann-in offered low-pressure service, processed our rebates with Washington gas for the upgraded furnace, and even did extra work to get us a partial refund for our older furnace directly from Carrier. We could not be more impressed. I highly recommend.

Contacted Mann-In to get an estimate for a new system after our system shut off while the temperatures were in the upper 90s. They made it a priority to come out that day due to our situation, and unlike other companies, provided us with a 30 minute window. By the next day we had a proposal in place, and even though they needed 1-2 weeks for installation, they made sure that they did whatever it took to get our A/C working until the replacement was ready. The day of installation was seamless, and the technicians were all very friendly, professional, and efficient with their time. I was originally told it would wrap up around 5:30, then on arrival 3:30, but they were finished around 3. I have been extremely impressed with this company and I would recommend them to anyone in need of replacement or regular service. I've had more than five different contractors come into my house for HVAC services, but none compare to Mann-In.

I selected this small family owned contractor in a field dominated by much larger companies largely because of a similar project they recently completed for my neighbor. It's been one of the best decisions I've made. Everyone I met and dealt with was professional, efficient in their work, and proud of the role they played in providing a great product. While near the high end of the price range of quotations for similar installations, Mann-In provided a broad range of equipment options with different energy efficiencies and price levels and thoroughly explained the benefits and limitations of each option. I felt they gave me a better framework to decide upon the option I chose. The installation was flawless, on time, and I am delighted with everything about my experience with Mann-In.

I highly recommend Mann-In for any of your HVAC needs. We used them for reducting our entire home, as well as replacing our entire HVAC system and they certainly exceeded all of our expectations! Buck is one of the most knowledgable HVAC technicians I have ever met, and he carefully reviewed and explained everything to us to fully ensure of our comfort and satisfaction before any of the work was to be done. Buck performs the initial consultations and went out of his way to fully explain and resolve all questions and concerns. Chuck, the owner of the company, was fully involved throughout the entire process (from start to finish). Chuck came out to our house to perform a full inspection and came up with a very creative and well thought out design for rerouting the ducts in our home. Mann-In was able to accommodate reducting our home in ways several other highly-rated HVAC companies could not. They are true experts in HVAC and really care about the work they perform. The technicians that performed the reducting of our home and installation of the new HVAC system did a fantastic job. They were very courteous, thorough and clean (they even vacuumed the rooms they worked in daily). It has been several months with the new system and new ducts and we are beyond happy. The air is so much cleaner, temperature is fully regulated in every room, and we fully trust Mann-In to take care of us for all of our future servicing needs. Thank you Mann-In!

Our 18 year old builders grade HVAC system was approaching end of life. The unit was a Rheem that ran off propane gas. One of two original HVAC systems in our home. So, we proactively decided to retire the original system this spring. I have been a Mann-In customer now for around 10 years now. They already replaced one of my two HVAC system 7 years ago. Also hot water tank about 5 years ago. All in all very happy and familiar with them. Very professional proposal with half a dozen options both in terms of level of efficiency, upgrades such as humidifier and better air filtration, and warranty upgrade. Competitive pricing. Mann-In scheduled my install within a week. I made sure I got on their schedule before the spring. As always, Mark and the installation crew show up on time and hardly take a brake till job is done. Meticulous work. They put drop clothes everywhere. I've tried the other giant heating and cooling companies in past. But, I prefer the more personal, responsive, and nimble Mann-In. Still run like a family business. Although, I am seeing more of the owner's son ( Trevor), Chuck Brown still comes out to pre plan the major projects and make sure everything is engineered properly for install date. He often points out or fixes things from previous builder. Thanks guys. Keep up good work.

There really aren't enough superlatives to express my respect and affinity for this local, family owned HVAC company. We have been clients for years (water heater, new attic heat pump, twice yearly inspections for our two units). When our old gas furnace set off the CO alarm in the basement they responded immediately to my concerns. They evaluated the problem and offered a plan to repair. Given the age and lack of efficiency of the old unit, I asked their thoughts on replacing the system. They promptly provided a proposal with options and presented the information in a clear and easy to understand discussion. No pressure to buy the new unit, just the facts. This is absolutely consistent with prior experience in their replacing our water heater and heat pump in our large home. These people are consummate professionals who respect the client, know their products and deliver on their promises. This applies not only to the service personnel, but the office staff as well. Outstanding customer support and service. When is the last time you had the owner of the company come by to make the final measurements before approving the installation just to be sure everything is perfect? They managed the county permit and the inspector's visit, provided all the completed paperwork for the Washington Gas rebate, and gave us a discount as we are clients. Wow. The new unit was installed within a couple of days, even though I had to be out of town. They coordinated with my house sitter and got it completed so I returned to a warm and cozy home. I can confidently recommend this company.

Despite being a really bad cold snap, when they were surely inundated with calls, they got someone out quickly. He found the problem right away and fixed it quickly and pleasantly. I would definitely hire them again.

After getting quotes from several businesses, I decided to go with Mann-In. Why? Professionalism from top to bottom. No corners cut. They took the time to fully understand my needs and concerns, and they were the only ones to actually come out and take measurements for how to design the new system. They took the measurements once for the bid, and then again, in even more detail, after I accepted the bid. I would without hesitation recommend Mann-In for any HVAC work that is needed, although I believe they are specifically focused on Carrier systems (you'll need to verify that).

We have used Mann-In for over 20 years and they have always been professional, prompt and dependable. They are in line with prices and have never suggested anything that we really didn't need done. We have our yearly maintenance thru them and they notify us twice a year to schedule, show up on time and complete the checkup. We would highly recommend them.

We've used them for decades. They are beyond belief they are so good. This time, they had to order a part, but they came out as soon as it came in. This was covered under warranty, so there was no charge. Everything they get is an A. They are so good! We've had our whole house system replaced twice by them because we've been in our house for 26 years. They are just unbelievably good. Their people are very personable, helpful, professional. They're not enough superlatives for them. They're always so good and have been since we've been using them.

Everything that they get is an A. Always! They came prepared to do the replacement and finished it in one afternoon. It was lengthy. It took them about 4 hours worth. They replaced the unit as well as any internal parts that needed replaced due to new technology. We had a discussion with them about what we would replace or update before the installation. They came prepared and did it. Everything was working fine before they left.

We've used them for years. They installed our A/C years ago. We have a contract with them and they come out twice a year to check it and clean what needs cleaning and tell us what's going on. We love them, they are pretty far away from us but they always come in a real timely manner. They are very nice and very thorough. We always see the same 2 people, one or the other, so they know our air conditioner very well and know what to look for. They do a really thorough job both inside and outside, just awesome. If we have anything wrong we call them because certain things are covered in that contract. They never leave us in the lurch, ever. There are some that are cheaper but they don't include as much. I know we are pretty far out of their area but they always make an effort to meet our needs.
Description of Work: They come out every 6 months for to give us a checkup. This was the winter checkup.

We had an older A/C and everybody was telling us oh it's dead and you have to replace it. They came out and worked on it and we were able to use it another 4 or 5 years before we purchased the new system. They were so efficient and good, they were recommended by a friend. When we called them, we thought oh they will never want to come up here, I think they were in Sterling at that time. They said they had an worker that lived in our area and so they included it either when he was coming home or going to work so it worked out for both of us.

They did an excellent job on all of the tasks. The work was done soon after my old system failed, on time, with no problems. All of the workmen, staff, and the owner are very caring and professional. They showed me how to use the new, internet-connected thermostat, which provides a boatload of information about the system and weather and permits customization of many system parameters. They advised me on how to minimize temperature variations between floors. The servicemen performing the semi-annual service calls are very good too and they arrive as scheduled, with automated notices that they are on the way. I am very pleased with all aspects of Mann-In's operations over many years.
Description of Work: They replaced my gas furnace, A/C unit, humidifier, and thermostat with a Carrier Infinity system. They removed my old units, moved the location of the outdoor unit and added a basement return. I also have had a service contract with them for many years, including repairs.
