Queen City repaired our Geo Thermal unit which had a leak. The technician, Reece, was…read moreknowledgeable and professional. The repairs were completed in a timely manner and the work was thorough. He went above and beyond to make sure our unit was repaired properly with the highest quality parts. We were very impressed with this company. Previous, we had another company out for a diagnostic, but they were dishonest, charging us ridiculous amounts of money. Queen City was reasonable and fair. I would highly recommend them to anyone in need of HVAC maintenance or repair.

I purchased a 60 year old house in Springfield that hasn't had the air ducts cleaned in probably…read moreahem, 60 years. I mean they were nasty. On top of that there was a problem with mold under the house. Once I had that remediated Enviro-Air came out and got to work on the ducts. The job they did was amazing. It took them several hours and they were thorough both before and after the job as they cleaned up after themselves. They took plenty of before and after pictures of the ducts to show what they accomplished and it's a night and day difference in what the ducts looked like. To think we were breathing all of that stuff in. Yikes! I suffer terrible allergies as well, so all that dust couldn't have been good for them. People usually don't think about general home maintenance on things they don't see, such as water heaters and air ducts, but don't neglect these things because you'll be sorry if you do and the piece of mind you will have knowing you are sleeping in a safe environment is priceless! Thank you very much Enviro-Air. You guys did an awesome job!
