"Sergio and team did a great job on our kitchen floor tile installation. From making recommendations on tile selection to meet our needs, to leveling our subfloor, to cleanup, they were professional and courteous. They provided excellent quality. We are happy to give them our highest reference."

"I was having trouble with one of the zones in my house with our alarm we purchased with ADT Premier Provider. Ryan came out and checked the system and the battery in the control box; and those were all good. He determined that the sensor on the slider door was the problem. He cleaned the track, reinstalled the sensor on the door and secured it. The last thing he did that put his service OVER THE TOP was that he knocked down a large wasp nest that was in an area I couldn't reach even with a ladder. This was the best customer service we’ve seen in a long time!!"

"Long, took 11 1/2 hours. They had warned me that it could though, and that there was no way to predict if this install would be a long one."

"Scott and his apprentice were excellent. I would highly recommend his service. He is very professional and punctual. They installed two ceiling fans in my bedrooms. My master bedroom didn’t have attic access and he was able to think outside the box and install the fan. His price was very reasonable and he did superb work. Thanks Scott!!! Any electrical work I will need in the future, I’ll be calling Scott!!!"

"Polar sets the standards for excellence. I could not be happier with my decision in hiring Polar to complete my new central air install. Everyone I spoke to was knowledgeable, professional, customer service oriented, and thoroughly answered all of my questions related to the different options that would best efficiently suit the needs of my home best. They did not try to push unnecessary equipment or sell me something that I did not need. The installers were professional, polite, punctual, respectful of my property, and cleaned up after themselves. After the install was complete, they thoroughly went over the system, all the paperwork, and answered all of my additional questions. I would definitely hire them again for any other heating/cooling/plumbing needs."
