What People Say
Testimonials
Anthony arrived to the appointment exactly at the time we scheduled, listened to what I had to say and inspected the system. His feedback was exactly what my research had led me to expect and I could tell he was being honest. He offered 2 options in his quote and then provided a third at my request, which ended up improving the SEER rating for the system I wanted.
The pricing was within the range I expected and he guaranteed he could have his team out within a week if needed. He did exactly that.
We scheduled the service date for today between 8AM - 9AM. At 8AM I see 5 company vehicles pull up to the driveway, and begin to unload a ladder and equipment. They introduced all of the team and provided me with an explanation of what they planned to get started on. They quickly spread out drop cloths in all the areas they expected to need access to, ensuring they protected my carpet and stairs; they even brought their own shoe covers too.
I love tools and learning, so I hung out with the guys (Mike and Mac) working on the condensers outside and really had a wonderful time talking with them. I was out there for 5 hours but I had a fantastic experience and these guys are just really honest and down to Earth; nothing but good vibes!
Carl and Oscar (I hope I'm spelling it correctly) were also really great guys and did all the work replacing the evaporator coils in the hot attic; they offered to paint the attic entrance (I had damaged the day prior) and made sure to vacuum any bit of insulation that had found its way out during the installation.
Anthony made sure everything was done perfectly and that the show ran smoothly; we got a chance to speak some more and he answered a few more questions for me.
These guys were nothing short of fantastic!! I honestly had just the best experience with the entire team, and really appreciate the respect they showed my home and family.
Anthony, Mike, Mac, Carl, Oscar; you guys ROCK!!! I really appreciate your honesty, experience, and effort in completing a job originally scheduled for 2 days in only 1! My house is now ready for the summer and you turned an event I was dreading into a really positive experience!
I will happily recommend you guys to my family, friends, and neighbors!
Thanks for much for the service! Will definitely be going with this company again.
