They took the time to thoroughly clean the condenser and ran multiple tests on the attic unit to make sure everything was operating as it should. What really stood out was how they walked me through the entire process at the end, showing photos and explaining each step. It gave me a lot of confidence in their work and attention to detail. I'm very happy with this company and would highly recommend them.

Good move! 1) Making maintenance appointments is easy, but it is even easier to make an appointment when there's a problem with one of our systems. They really are there for us when we need them. 2) From the moment they arrive until they depart, it's service with a smile. Check out my photo of Diego and his special carpet arrival! They keep their booties on in the house, too. 3) Our systems are running well. Poor installation problems caused by previous vendors have been corrected. 4) Pricing has been fair.

The owner of the company provided our estimate, the team arrived within the time windows predicted, they were competent and courteous, and they did a *fantastic* job modernizing our system to heat quietly and evenly throughout. They added a vent to a bathroom that had been inexplicably left without one, improved the insulation throughout, and added an attic walkway for safety. We've been tolerating very uneven temps and noisy vents for the past 10 years, and I wish we would have discovered Green Collar sooner! It is *NICE* in here. I have no reservations about recommending Green Collar's services. Stay warm, y'all!

We had these guys come out last weekend to look at our AC unit that was making noise. They happened…read moreto have availability the following morning, so out of convenience, we went with it. The guy who came out was super nice. He diagnosed a bad compressor (in our 2 year old system) within minutes. Obviously parts are covered under manuf warranty, but we were on the hook for labor and somehow also the cost of freon (not unique to this company, but what a sham). Where it gets interesting: We were initially told it was $1600. Somehow after I had said yes, the estimate jumped to $2600. Supposedly this was due to the size of the unit and the amount of freon - our system requires 8lbs 2oz. Sticker shock on sticker shock...but whatever. We were just hoping to get out closer to the first estimate and moved forward with the appointment while the weather was nice. On the day they were scheduled to come, we were given a window of 8-12AM but told it would likely be around 10AM. We obviously made arrangements to be home. By 1PM, we had still not heard from them. My partner called to check in, and he was told by the office that they were running late on a job but would be there shortly. By 3:30PM, we had still not heard from their office. We ended up just canceling the appointment... These days, there's just no excuse for poor communication. It's super freaking rude to leave people waiting - people who have taken time off work to make sure they're there for the appointment window you provided to us. It's not that hard to keep people posted if things change. I fully respect the fact that other jobs can run late, etc. But to miss a 4 hour window by 3.5 hours without even a call to us is beyond ridiculous.
