"These guys did a great job! I was called within 1 minute of requesting quotes for this job. I was given a reasonable quote promptly. Within a few days the unit was installed and is working wonderfully. I have to point out the technician that did the install. Josh was courteous and professional at all times. He stayed in contact with me thru the whole process. I would absolutely recommend this company and will to any of my neighbors that have such needs."

"The tech came out and spent a lot of time trouble shooting my HVAC issues. When the thermostat was determined to be the problem, he left a temp until Nest could mail me a replacement. After leaving a 4 star for quality I was called and harrassed why I didnt leave a 5 star review. I explained my reasoning, but the man on the phone wanted to argue and was obviously perturbed by the 4 star in that area. When I tried to get them to complete the work needed, he generated a quote that was 4x what I ended up paying from another company to avoid coming back out to the house. I didnt appreciate the way the phone calls were handled. The tech who came to the house was very polite, and explained everything to my wife so there was no misunderstandings."

"Fantastic! We had hired a handyman from SMAP ( send me a pro ) to install a new bathroom door for us and he did such a terrible job that the door would not even close. Hg came out and corrected the situation so we now have a perfectly functioning door. We now know who to recommend , and who not to recommend, when work needs to be done."
