They were super patient with my stubborn old painted over air vents. My house feels like a new home now that we are breathing fresh air.

He walked us through the process, so we would know exactly what to expect. He was very knowledgeable, and answered all our concerns.

I reached out to Jason to test and remove mold in a home I was trying to purchase. He confirmed…read morethat he was licensed to test mold with my realtor and broker on the phone. I should Have known he was not legit when the receipt and estimate he handed me was not for mold testing but for carpet cleaning. My bank questioned if he was licensed. When I asked him to provide the info to the bank he replied that he was not actually licensed to test mold. I asked him for my money back. No reply. I left a 1 star review and he called me to yell at me and cuss me out. I have a pending claim with better business bureau. When better business bureau reached out to him, he said he would give my money back, only after I removed my honest reviewHe has since stopped replying and has not returned my money.

The results were great. Jason is flexible about quoting to meet your needs. I hired him again to clean our hvac ducts. 1/16/19: Jason came back and cleaned our dusty ducts. We have a former duplex with two separate hvac systems, and he gave us a package price along with UV sanitizer lights. Again, fast, efficient, and professional. By the way, after posting this review I saw a couple of older negative reviews. I found Jason through A's List, which has overwhelmingly positive reviews going back at least a couple of years. My experience with Jason was that he was easy to deal with and very responsive to my calls.

Thielmann: I'll try to give a brief background. The furnace (unit also has AC component) in my…read morecondo was having white smoke/steam come out of the external vent during some of the extremely cold weather we were having. Even though my furnace was not making any unusual noises, smells, or setting off my carbon monoxide detector, I was still concerned as no other condos in my building or nearby buildings were having the smoke/steam. The employee that initially inspected by furnace (Carlos?) informed me that the heat exchange was clogged and would require me to repair the furnace or purchase a whole new unit (I opted for a whole new unit based on its age). Carlos gave me the impression there was no rush and that it was not something that necessarily needed to be done immediately. When the second employee (Dave?) came later that day to take measurements and verify the replacement unit needed, he made it seem almost emergent and began to wonder aloud if he needed to shut my furnace off that day. The stark contrast between the two was alarming and created a bit of a trust issue on who to believe. Carlos seemed a little green and Dave seemed like more of a veteran. Dave eventually determined it did not need to be shut off as no carbon monoxide was entering my condo. The whole experience did create a bit of a panic for me though, so I quickly accepted the only available appointment within the following two weeks. It was convenient that they could get it replaced just five days later, but if it truly wasn't an emergency then I would have liked a little more time to verify I was getting the best price as it wasn't cheap (to give you an idea this is the largest purchase I've ever made behind my home, education, and car). They do offer payment plans that were easy to enroll in, one of which has 0% interest if paid off within a year. I'm not trying to throw anyone under the bus, but I can tell they really want an honest review as I've received multiple texts and emails asking to leave one. The crew that showed up on the morning of 12/24 to install the new unit were quick and efficient. They were respectful of my property and explained the new thermostat to me. All the employees were friendly, including the ones running the office over the phone (Micah?).
