"Tom and Pouria represented the ethos Bob Jenson espoused when he started his business many years ago. He would be proud to know how well they represented the company. Not only the intelligent approach, but their humanity...you could sense it was not just a job-THEY CARED about the customer. -Carl Boucher"

"I have never in 40 years of purchasing services been more impressed by the level of service and professionalism exhibited by Ryan at Airtight. The installation was performed impeccably, with attention to detail. Ryan kept me informed throughout the installation process. The project was delivered on budget and on time. Airtight is truly ethical company. Ryan was great to work with -- completely trustworthy."

"Every year in Spring we have our air conditioner serviced. This last Spring, Anderson Plumbing came out and did the service. At the same time saying that our heater was needing a new part and shutting that system down. Last week Anderson came out to look at the heater. Said it needed a ?minor? repair for $700. We had someone else come out today for a second opinion. He was from Evo Air. He looked at everything, nothing wrong at all!! Turned the system back on and everything works fine. That is what honestly and integrity looks like! Completely a free visit. Again, NOTHING AT ALL wrong!! $700 could have been wasted on a scam by Anderson. "

"Carini installed my mini splits a few years ago and promised me the world with their warranties. Well, turns out they botched something during the install and all of the refrigerant leaked out. They want $2,200 to refill and re-pressurize the line. Since they cross-threaded the screw that led to the leak during installation, this should be covered under the "Lifetime Craftsmanship" guarantee. Instead, they're trying to charging me a full day of labor to fix their mistake. Support on this issue has been dismal. It's been 16 days since they first diagnosed the problem and I still don't have a timeline for when this will get fixed. I chose Carini because of their warranties and their service record, but its all smoke and mirrors. You've been warned."

"My AC's secondary drain was leaking due to a clogged primary line. Daryle from Cool Air quickly identified the issue and cleared the clog under the master bathroom sink — about a gallon of water came out instantly. The final charge was a bit more than quoted, but Daryle was honest, efficient, and didn’t try to upsell anything. After bad experiences with Service Champions — who I believe sabotaged my system — working with Cool Air was a relief. Vadim, the owner, was also great to talk to. I’ll be using them again."
