His work and crew was top notch, he took the time to walk me through the whole system, things to look out for in the future. Did not try to upsell me on things I didn't need like the other three prior companies and took his time to do the job right and clean up after himself leaving my home looking better than it was before. Wayne is the man and I can't thank him enough he will get all my HVAC work moving forward!

I called and was told the plumber would call me back. Vernon called me back within 2 hours we set up for him to come the next day. He showed up as promised and replaced a kitchen faucet and reset a toilet that the flange had rusted out. Very reasonably priced. I had a water heater that was beyond it's expiration date. Set up a date for the following week. Vernon called me on Tuesday morning as promised. He was at my house on time. Had everything he needed for the job and did a great job. In my younger day I would have done this work myself. Nice to see a professional show up on time. Do quality work at a reasonable price. I now have a a new plumber for the next 30 years. Thanks Vernon.

We understood that we were working with a small family-owned company that did not operate 24/7, but after many calls over the course of a year, our calls have not been returned. Therefore, we were not able to use our service contract. Considering the great work they did when they did respond, this has been very disappointing.

Extremely disappointed with Blue Dot…read more About four years ago, I paid roughly $18,000 for a brand-new HVAC system expecting reliability and quality service. Instead, I've dealt with recurring issues over the years, including multiple problems within the last two weeks. Most recently, my AC stopped cooling properly during extremely hot weather. I scheduled service and was given a 2-6 PM arrival window for 5/20/26. No one showed up. I called multiple times that evening and was repeatedly told the issue was being "escalated" and that dispatch or management would contact me. No one ever did. I called again the this morning. The representative could see all prior escalations but could not explain why no technician showed up or why no supervisor contacted me. I was again promised service between 2-6 PM today. Again, no technician arrived. Meanwhile, my system began freezing over, with visible ice/frost on the indoor lines and outdoor unit. I ultimately had to shut the system down entirely to avoid possible further damage. I called once more and was told the local branch and management had already gone home for the evening, so no one could provide answers or assistance. At this point, this is heading into a third day with no service, no management follow-up, and no resolution. I understand HVAC companies get busy during extreme weather, but the lack of communication, accountability, and follow-through has been unacceptable, especially after investing so much money into a system that has had recurring problems since installation.

I saw several…read morepeople recommended Eco-Cool on another local persons request for HVAC recommendations as well as several other companies. I researched reviews on all and Eco-Cool was my initial top choice after the research. I called the office to schedule a routine servicing of our system on Friday, I spoke with Amy at the office, she offered several options for services including a simple one time service or an annual program. We were able to schedule a tech to come out on Tuesday morning. Our Tech, Craig, was prompt, courteous, and professional even through the multiple questions I asked. He took a look at our system and the area of concern we had and he gave us the news we were anticipating (that our system is running but might not have much time left in it....it's 26years old) he offered to have quote for replacement drawn up if we wanted. (I did) he left us set up for success and he told us his goal was to keep us running into springtime at least....we appreciated that! After he departed, I called Amy again to arrange payment for today. She was kind and professional and let us know she would have a quote to us by the end of the week and even provided insight to what pricing is doing now and anticipated to be after the new year so we could be able to make the decisions best for our family. We appreciated the prompt, professional, expert care we have received in our first few interactions with Eco-Cool and are looking forward to remaining customers for a long time!
