Blue Dot did a great job installing our new HVAC unit! Matt G.and Steve were excellent! They did a great job getting the old heating /AC unit out of our attic and put a new one in it's place. They setup my system, explained the operation and cleaned up. Every time we use blue dot we are happy!

Just had Keith K. and Jason A. from Blue Dot Servies install a new A/C and furnace in my home. Both did a great job getting the old heating/cooling system out of my house and installing the new one. They setup my system, explained its operation, and cleaned everything up wonderfully before leaving. Hope to have many years of continued great service from Blue Dot.

Thanks guys!

Ray and I have been customers from the previous company, Ridge Service, to Blue Dot Service. We have complete confidence in their service and they reply to our calls immediately and give us very professional information as well. Their Service Specialist is exactly that, a Specialist. If you want to be worry free for your HVAC Service call Blue Dot.

Problem with "dirty sox" smell and called Blue Dot.

Kevin L. came out within an hour of the call and he

quickly diagnosed the problem & fixed it. Additionally,

he installed an air scrubber in our AC system. The process

took less than a half hour and now our house smells

fresh and cool, too! Thank you Blue Dot for prompt service

and solution to the "dirty sox" smell!

Was having a problem with the outside pipes freezing over. Kevin L. arrived quickly, diagnosed the problem, and fixed it. Very fast, courteous, and professional, and gave the entire system a quick check, too. Outstanding service!

Keith R Outstanding Service

Keith R checked our heating and air conditioning for the spring review portion of our Blue Dot maintenance contract. He was both courteous and informative. Blue Dot is a great company. We've been with them for over a dozen years!

I want to say THANK YOU to Mark Bartholomew, Supervisor for working with me over a 4 month period to resolve the billing dispute I had due to a defective part in my Carrier Heat Pump. He sent several technicians to inspect the unit and always returned my calls. He was patient, courteous and professional throughout this "ordeal" (for me) and he sent me refunds to cover the excessive BGE charges.

I also want to thanbk Jeff Martin, specialist # HCC08, for coming back as soon as possible to add refrigerant after the last major repair. He was respectful of our property , courteous, and he answered all of my questions.

I will recommend Blue Dot to all of my neighbors and friends.

Darren R. is professional, knowledgeable and a down-right-nice person. Every season when we make our 'Blue Dot Maintenance' appointment, we always ask for Darren. I'm sure everyone who works for Blue Dot is great, but we will wait for an appointment just so we can have Darren come out to the house.

We were impressed by Thomas' professionalism and knowledge. He explained exactly what he did and answered our questions. He was most personable.
