The technician Slade was very courteous and knowledgeable. Previous inspections by other HVAC contractors have been usually disheartening since they would come up with other items that needed attention for a newer furnace. I like these guy enough to enter into a service contract with them.

About five years ago I had a furnace problem and Precision fixed it at a fair price and did good…read morework so I've been using them for about five years now to come out and clean/tune my a/c and furnace every year and couldn't be happier with their service and professionalism. Sadly, because they are a smaller company they don't have after hours service but on the plus side they have a perpetual 10% off or $25 discount coupon on their website (I think there is a free hat coupon there too). My a/c unit is from 1998 and still running thanks to their great tune up and maintenance skills!

RE: Beyond 5-star service!…read more In early spring, our family returned to our newly build home for the second time to find an extremely cold walk-out basement and continued breathing/health issues. We received a referral from 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 a newly constructed home that required us to stay in a hotel for over four months due to formaldehyde levels making the home uninhabitable. The basement required complete renovation of the basement joists to fix the product omitting lethal levels of formaldehyde. Once completed, our basement was 15-20F degree difference from the other levels on the home, Air Exchanger 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 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 home. Tom from ENVIROWORLD USA not only fixed our cold basement but turned our homes air quality to hospital grade levels with HEPA Home Filtration System, delivered the experience of the exact same temperature across our entire three floors, and Steam Humidifier. 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 knowledgeable Indoor Air Quality and HVAC expert, he is extremely passionate for the work he does and delivers results with everything promised and more. I would highly recommend Tom from ENVIROWORLD USA to help with any home air or heating you may face and would graciously just like to say, Thank You to Tom and 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. Sincerely, The Lambert Family

Had an issue with another company that installed the unit and didn't trust them so looked on here…read moreand found Enviroworld. Called them on a Friday at 7 at night expecting to leave a message but the owner, Tom, was available and answered. Told him the issue and he took the time to talk with me and understood my concern. When he looked at the mini split unit, he diagnosed the Freon was low. The unit was installed in May and he said there was no way that it should have been gone by now. Thought that the company, who apparently has good reviews, put in a small amount to begin with. That company suggested that a part was the issue and that it would take hours to fix. It's hard to find honest contractors but feel Tom has the owners best interest at heart and will use them again.

We had a wonderful experience with JG Duct to have all our house vents/ducts cleaned out. We…read moreinitially put a request on Yelp to get quotes. JG was prompt on getting back to us right away with an estimate. We then spoke to Amanda who helped us figure what we needed and book us a time and day. The owner Jimmy arrived with Oscar to take care of us that day. They gave us a text about a 1/2 hr before that they were in route. Jimmy was very friendly and explained everything as he was working, showing us videos of the inside of the vents as he started cleaning them. They worked promptly to look around the house to start working. They first covered all the vents and brought in their equipment. Each Individual vent was cleaned. Th package included the dryer vent and furnace but we paid extra to get the bathroom fan cleaned inside and thru the outside. They cleaned up and were done in about 1.5 hrs for our 2600'sq ft house. I would definitely recommend them for any duct work you have. They were very prompt, professional and have great customer service!

We were recommended to contact DNA when our air conditioning unit started acting up and Dana answered right away and was able to come out to our place the same day to check out our concerns. Dana was kind and took the time to educate me on the air conditioning unit & furnace so that I could take the necessary steps to better ensure longevity of both units and reduce the need for future servicing of them. He was able to address our concerns quickly & informed us of future expectations for the unit and current anticipated costs associated with repairing / replacing it. Dana's prompt communication and expertise are invaluable and I cannot recommend DNA enough! We are so grateful to have a heating & cooling company that we can trust and rely on.

My AC stopped…read moreworking, and after texting multiple HVAC repair companies, Mario was the first to respond, which I appreciated. I mentioned that we didn't need an emergency visit and he fit me in his schedule for the next morning, quoting $175 for the service call. After diagnosing an electrical short in the contactor, he left to pick up a replacement part, and finished the job that same day. At no point, before or during the repair, was I given a total cost estimate outside of the initial $175 or a chance to approve the total job amount prior to completion. It was shocking, then, that the final invoice came out to $800: a $175 diagnostic fee, two hours of labor at $175/hour, and a $275 charge for a part (contactor) that retails for $50 or less. In addition, I wasn't given an invoice upon completion of the job, but rather I had to ask for it twice afterward. If any part of this review gives you pause, I'd consider taking your business elsewhere.
