"Best Air Quality and Restoration did a spectacular job! I can't say enough about the employees. They did an outstanding job! They were punctual,polite and followed social distancing protocols.They assessed the home and cleaned the air ducts quickly and efficiently. I am very pleased with their service and highly recommended this company. I purchased a new home and had them come clean the ducts to improve the homes environment. They showed me before and after pictures and I noticed a difference right away"

"The sales rep was very attentive when coming over and designing a solution to our heat and air needs. We were able to get a large team of workers here and knocked out an entire house install in one day. Some trash and miscellaneous items were left in our yard. When we needed additional items from the sales rep he will respond back saying he will take care of it but still has not. I have brought this up to him over 4 times and I still get nothing. The price seemed pretty high, and we had to shop the price around some but the company came with good financing options and some guarantees that others could not. The mini-split units work great."
