"Poor communication around the amount of dust that the installation would leave or that we would need to remove any belongings from the attic or most importantly the adjoining closet where my wife stored her wedding dress. The install crew was also careless, leaving very noticeable scratches and dings on window and door frames. Management promised to address these repairs and dry clean the wedding dress but gave us the run around for months without addressing any of the issues caused by their crew. What’s arguably worse is we haven’t seen anything close to the amount of savings on energy bills that was promised in our first summer with our new insulation."

"CMA came out to install two air conditioner units in my home in 2019. About a month ago, I the downstairs unit stopped working. I called them and they came out and told me to change the filters. Of course, that did not work. I called them back and told them that was not the issue, and they gave me a hard time about coming back. When they came back the second time, they found that the fan in the downstairs unit had stopped working. The parts are under warranty, and I paid roughly $400 for labor. Yesterday I called them because my upstairs unit was not working. The woman in the office said that they were booked out 3 weeks. I told her that since I had spent over $10K with them for the units in 2019, I think they need to come back and fix the issue. The woman then stated that the technicians did not want to come back. I nor my husband were rude to any technicians when they came to work on my units. However, my husband is black and I am white, so maybe the problem is that the family owned company are a bunch of racist. I would not use this company unless you enjoy throwing money away and horrible customer service for spending your money."

"A company like no other. That is the best way to describe my experience with McClintock Heating and Cooling. We have been with them for about 4 years now, 2 houses later, 5 units services, 2 units replaced (which were both 20+ years old), they have taken care of us time and time again. We most recently had an issue with our refrigerant line, which was condensing on our sheetrock in our bedroom and staining the wall. McClintock had Jason (shoutout to him- he rocked) at our house on the same day and addressed the issue. They, then, worked with us and had the wall repaired and restored to better than it was before within a few days. Baylee, Amber, and Larry were exceptionally kind and patient with me- answering my questions and restoring our home. I never thought that I could love my HVAC servicer, but they bring a little Heaven to Earth in their kindness, generosity, and humility. I wish all companies would follow their example. "

"Just cancelled service today. Have been a customer of McNeeley since 2014 and never experienced such terriible customer service until now. I don't know how BugOut expects to keep customers unless they are going for quantity to the point that it doesn't matter. Too much to even post here. Will find a local company who cares about their customers like McNeeley did instead."

"We had our whole house done in Hardiplank including all of the trim and soffits and had some gutters replaced. Lasting Impressions did a fantastic job. Our house was old so there needed to be some wood replaced but they always informed us and waited for our approval. Once we did approve they were quick, professional and high quality with all their work. Our house looks great. They were by far the best price for the work they did and Eric was great to work with. Very responsive and made sure it was done right."

From The Owner: I am a second generation contractor with over 15 years experience. Having grown up in a small family remodeling business household, I began honing my skills at a very young age. I truly enjoy helping homeowners with their home repairs. We specialize in roofing and exterior repair along with a wide variety of Handyman services.

"Not well!! Would NOT recommend Kevin with McToolman! He was hired on a sub-contractor basis to install crown molding and used wrong nails (too long) that punctured holes in my AC freon line and a waterline. These were expensive repairs and he is claiming "no fault". Contractor and several others surveyed damaged and confirm he is at fault, plus their are clear pictures proving so. For someone that guarantee's his work, he is running from this "at fault" claim. Can only wonder how many other times this has happened. Look elsewhere for your service needs."
