Customer Testimonials

Your commitment to excellence and doing the job right was stellar. These guys really know their stuff  too. From our own experience, they were definitely not your typical same day, out of box, basic, inexperienced HVAC company. We knew we could trust them right from the start of our project. Very knowledgeable as they knew immediately from decades of diverse experience what our concerns were with our new home.  By far, head and shoulders above all other HVAC companies.  Originally we had another large HVAC company bid our new home. After further review of our findings, the HVAC system by others was grossly undersized, would of never kept up during our extreme weather or performed properly. ENVIROWORLD USA "properly" sized the equipment capacity of our home with multiple HVAC Systems, added Floor by Floor Zoning which proved their own calculations to be right. It was a very easy choice. We were referred to ENVIROWORLD USA by our builder Carl M. Hansen Builders, whom gave rave reviews of their industry expertise and commitment to excellence. As well, also did extensive HVAC work in our own builders home too. Their leadership,  vast knowledge, compassion and  communication skills were outstanding. Our new home covers around 7,500 sq ft with an indoor basketball court. Tom not only designed an integrated and complete HVAC system with three separate heating and cooling systems that maintained even temperature year round, room by room, floor by floor, but kept his promise that our home would be very cool during the summer, warm and comfortable during the winter for many more decades to come.  Our Upper Level has many windows and covers 3,000 sq ft alone. Even on the hottest 110F and coldest -25F of days, ENVIROWORLD USA was able to provide even temperatures within 1 degree from end to end, corner to corner across this wide floor plan. Our indoor basketball court has 22 ft ceilings with large air vents from ceiling.  Our amazement was the superb movement of air coming down overhead from our 22 ft ceiling areas during heating and cooling season.  Our older home of 1800 sq ft, we could never feel air from our floor vents. What an amazing difference in overall comfort within our new home. This company designed and built a custom made indoor environment that is second to none. Having recently been diagnosed with lung cancer this year before we built, made our choice with this company a slam dunk. Dusting is less often and the air in our home is much fresher than ever before. Remarkable. We have seen a dramatic change in my personal health and my son with severe asthma. My son was using his inhaler several times a day in our previous older home.  Since living here, he virtually quit using his inhaler. Truly amazed with the detail and scientific knowledge that was applied to every facet of our Home Comfort Systems. Very impressed with our indoor healthy air system and overall results.  This includes our Hot Water Steam Humidifiers.  No winter maintenance which was a relief. Humidifiers made our home even more comfortable during winter. This company is the absolute, very best.

Beyond Five Star Service! In early spring, our family returned to our newly built home for the second time to find an extremely cold walk-out basement and continued breathing/health issues. As seen on television and the Chaska Herald. We received a referral from Reuben of Structure Tech inspection firm to contact Tom with ENVIROWORLD USA, turning out to be an absolute blessing for our family. Our home was impacted by the Weyerhaeuser toxic floor joists in our newly constructed home that required us to stay in a hotel for over four months due to extreme formaldehyde levels making the home uninhabitable.  The basement required complete renovation of the basement joists to fix the product omitting the lethal levels of formaldehyde. Once completed, our basement was 15-20F  degree difference from the other levels on the home. From ongoing Air Exchanger unit problems, HRV core missing, subcontractors not responding to our phone calls feeling hopeless with no-responses from our builder and suppliers who created the problem.  Additionally, the formaldehyde problem was "fixed", but my four-year-old daughter continued to battle with respiratory and otolaryngology issues daily inner ear infections/ongoing sinus drainage due to bad air quality in our new home as caused by our builder.  This fantastic company turned our basement and entirety of our home air quality into "hospital grade" levels with a large HEPA Home Filtration System and Steam Humidifier and delivered the experience of the exact same temperature across our entire three floors. Tom has always made us feel as his number one priority and have never experienced this level of customer commitment in my lifetime.  Not only is Tom the most experienced and most knowledgeable Indoor Air Quality and HVAC expert and is extremely passionate

for the work he does and delivers everything promised and more. I would highly recommend Tom from ENVIROWORLD USA to help with any home air flow or heating you may face and would graciously just like to say,  Thank You ENVIROWORLD USA for making our family happy and healthy again. 

This above and beyond service level should be recognized and acknowledged 

as the premiere, reliable, experienced, passionate experts this company delivers. 

Beyond 5-Star Service!

This HVAC company is the very best-- Replaced the builder grade junk in our house which was built in 2008. Tom has ran new gas line to my deck for grilling, radiant floor heating system and installed a whole house steam humidifier which we love.  Other industry professionals have witnessed their craftsmanship and made complimentary comments. Tom really knows his stuff.  This company is dedicated, compassionate and really cares about their customers. Provides world-class on the spot service, extremely knowledgeable and honest.  Old fashioned values. A hard find these days.  Highly recommend company.

★★★★★ Plymouth MN Timothy D. 2014/2018

We were referred to Tom by our Home Inspector, Reuben of Structure Tech. 

The odors and lingering smoke have been eliminated from within the home and are sleeping better with less fatigue.  Literally, within a few hours, I was breathing easier.  I can't say enough good things about Tom.  He is an IAQ (Indoor Air Quality) genius, with a deep commitment to customer service and follow-up support.  If you are having any issues regarding HVAC/IAQ, give this company, ENVIROWORLD USA a call.  You won't find a better service provider in the Twin Cities. 

 ★★★★★ Eden Prairie MN  John R. 2016

This note is to say thank you for all you have done for us way beyond the call 

of duty. How fortunate we were the day you walked into our lives. Previous contractors, and many over the years, told us we just had to live with all the frustrations of our geothermal heating and cooling system. Our air flow in home was inadequate as well. Always much too hot in our upper level during cooling season. Your multi-zone systems from floor to floor truly made a world of difference. Your ability to diagnose,  professionalism and resolve of our ongoing problems was immeasurable.  Good to have a real genius working in our home.   

★★★★★ Lake Elmo MN  Mary E. 2012

This letter is being written as a testimonial for your outstanding service. To 

say we are satisfied is an understatement. Your company is head and shoulders above any other HVAC contractors we have hired in previous years. I call you 

the Leonardo-DeVinci of my furnace room. Your company is prompt, friendly 

and honor your word.   

★★★★★ Edina MN  Joseph G. 2002

Tom is definitely the expert you need to get any HVAC situation in perfect order. I own a newer home 10 years old with very inconsistent heating/cooling and nuisance air flow problems since day one.  Tom very quickly and efficiently diagnosed the many problems and made corrections whereas other contractors had no clue. Due to very poor cooling in upper level. Tom diagnosed that we were lacking air flow by up to 60% in our upper level. Large upper area return air ducts were installed up through my hardwood floors from basement and with utmost precision. All seams were taped and sealed to prevent any air leakage. All blends in very nicely with my closet areas and surroundings. Night and day difference in the air freshness and even temperatures from room to room, floor to floor, truly amazing. Tom is the utmost professional and gets the highest of quality job done right at a very competitive price. 

★★★★★ Golden Valley MN Ed S. 2018

ENVIROWORLD USA really knows how to provide the type of Heating and Cooling system your home or business requires. After owning multiple homes 

have come to the conclusion that most HVAC systems that come with a house meet only the designed minimum requirements to save on money/budget. It is not until after the home is built that you truly are able to gauge your systems effectiveness and rarely do people make follow-up adjustments or investments. HVAC systems aren't pretty to look at, so people often spend their budget on hardwood floors, beautiful kitchens and more visual amenities. After living with these many frustrating comfort problems and without answers from other contractors, Tom clearly identified our problems and was able to make major improvements to our home. Tom is an absolute expert, perfectionist and was great at communicating and diagnosing our home. But really what sets this company apart from all other "broke/fix" out of box vendors that were unable 

to explain our situation was this company looks at the whole picture, whole house approach, based on your specific budget and comfort needs. 

★★★★★ Plymouth MN Matt E. 2016

I have a neighbor who is a chronic smoker. To make matters even worse, having COPD, I was getting a lot of residual smoke (carcinogens) second-hand cigarette smoke into my home. Tom completely overhauled my HVAC System with an emphasis on air quality improvements. Included special air purification systems, no cigarette smoke anymore. A large hepa system that connected to my house air ductwork, new central air conditioner, new aluminum indoor non corrosive cooling coil, no more refrigerant leaks and a customized air circulation system.  

I was truly amazed at the amount of scientific, detailed, knowledge that Tom has while explaining IAQ issues. Tom has a real passion for his work having lived his entire life with acute lung and breathing problems. Long story short, Tom solved all my IAQ problems. City inspector even praised the outstanding craftsmanship and quality of work. The other thing I really like about Tom is his commitment to customer service. I cannot say enough good things about Tom has a deep commitment towards customer service and follow up support. 

★★★★★  Eden Prairie MN John R. 2017

Would like to say Thank You to ENVIROWORLD USA. Grateful seems very inadequate to describe how much I truly appreciate all the hard work, compassion, dedication and scientific knowledge applied in my home.  

My trust was in your hands as you reached the very pinnacle of detail with 

my home. Your explanation of work performed throughout was an experience never seen before in my 35 years of home ownership. From relocation of air vents, air duct resizing, sealing of old air ducts, cleaning of debris even "after" 

I had my ducts cleaned, thinking they were cleaned by others was humiliating. Most of all you literally dropped my electrical usage with furnace motor and air exchanger  by over 75%.  New ECM motors did what you said they would do too. Most of all, you did show me the results before and after. My air flow in home has improved significantly. Even the noise from my furnace running all the time has stopped. You also  prevented my basement from flooding due to the lack of knowledge by other contractors. Truly amazing work. Also am very appreciative of your sensitivity to my budget restraints.
